The aluminum profile radiator is also called the radiator aluminum profile or the sunflower profile aluminum profile. The aluminum profile radiator has the characteristics of beautiful appearance, light weight, good heat dissipation performance and good energy saving effect. At present, the types of radiator industrial aluminum profile commonly used in China are: electronics, electrical appliances, computer radiator industrial aluminum profile, sunflower aluminum profile radiators, and power semiconductor radiator profiles. Aluminum profile radiators are widely used for their superior performance: machinery, automotive, wind power, construction machinery, air compressors, railway locomotives, household appliances and other industries. Now extruded aluminium sections is very common. Include aluminum framing system and aluminum curtain wall.The surface of the processed aluminum profile heat sink is anodized for surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum.

Aluminum profile radiators are widely used in industries such as machinery, automobiles, wind power, construction machinery, air compressors, railway locomotives, and household appliances. Aluminum processing, the aluminum ingot is processed into a material by a plastic processing method, and the main methods are rolling, extrusion, drawing and forging. We are also an aluminium extrusion suppliers. Aluminum processing began in the early 20th century in industrial production. Before the 1930s, it basically used copper processing equipment, which was mainly used in aircraft manufacturing. Now extruded aluminium sections is very common. After the 1960s, aluminum production developed rapidly, growing by about 4 to 8% per year. The products are widely used in aviation, construction, transportation, electrical, chemical, packaging and commodity industries. The output is second only to steel and ranks second in metal materials. In the mid-1950s, China built a larger aluminum processing plant and formed a production system. The products have been serialized and the varieties have seven alloy systems, which can produce plates, strips, foils, pipes, bars, profiles, wires and forgings. (Free forgings, die forgings) eight types of products. Electronic radiator, aluminum radiator, insert radiator, fork finger radiator, chassis integrated radiator, inverter radiator, lighting radiator, solar radiator, resistance radiator, comb radiator, industrial radiator And other products. Aluminum profile radiators are mainly made of high pressure cast aluminum and tensile aluminum alloy. Include aluminum framing system and aluminum curtain wall.
1 The heat dissipation of the aluminum profile heat sink is good, and the energy-saving features are very obvious. In the same room, if the same size radiator is used, the number of aluminum casts is less than that of steel.
2 Aluminum profile heat sink has good oxidation and corrosion resistance without adding any additives. The principle is that once aluminum encounters oxygen in the air, it will form an oxide film. This film is tough and dense, preventing further on the bulk material. Corrosion.
The pure aluminum heat sink is made of pure aluminum. Aluminum is the highest content metal on the earth. Its low cost and low heat capacity are its main features. Although it absorbs slowly, it radiates heat quickly, and the heat dissipation effect is proportional to its structure and workmanship. The more the number of sheets, the better the bottom polishing, the better the heat dissipation effect. The heat dissipation principle is very simple: use the heat sink on the heat sink to increase the contact area with the air, and then use the fan to accelerate the air flow and take away the heat sink. Heat. The heat sink made of pure aluminum is cheap, and the low-end CPU is cost-effective. We are also an aluminium extrusion suppliers.
The aluminum radiator profile is easy to process, and can be extruded into various tubular shapes with new appearance, which is in line with the current civil building decoration and decoration function; plus, the aluminum radiator has light weight and low metal consumption (metal heat strength can be Up to 2.0 to 3. 0 W /kg• °C), with energy-saving materials and other characteristics. Now extruded aluminium sections is very common.
In this respect alone, the aluminum radiator is one of the most suitable radiators for civil buildings. But the deadliest weakness of aluminum radiators is their severe alkali corrosion. Relevant research has proved that the aluminum alloy radiator without internal anti-corrosion treatment has a pH value of 5.0 to 8. 5, while the ordinary steel boiler requires a pH of 10 to 12, so there is no anti-corrosion treatment aluminum. The radiator can’t be used for the heating system directly supplied by the regional boiler room. For the central heating system of the district heat exchange station, the pH value of the water quality requirement is 8.5, which can be used, but it is necessary to pay attention to improve the system operation management level and ensure the pH value is not high. Include aluminum framing system and aluminum curtain wall. For single-family small systems that are self-heating, such as the use of gas-fired water heaters or electric boilers for each household, there is no such problem.
The conditions of use are relatively best. The most reliable way to solve the internal corrosion problem is to use aluminum-copper composite materials. Include aluminum framing system and aluminum curtain wall. The aluminum radiator should solve the connection problem between the nozzle and the steel pipe regardless of whether it is treated with internal anti-corrosion treatment. It can be solved by plastic joints or other methods. At present, the anti-corrosion technology of aluminum radiator has made breakthrough progress. We are also an aluminium extrusion suppliers.
Now extruded aluminium sections is very common.The anti-corrosion material and coating process show good corrosion resistance in short-term engineering practice. It is believed that with the improvement of scientific research level and the accumulation of practical experience, China will make great progress in anti-corrosion technology in radiators. The aluminum resources are much richer than copper and the cost is much lower than that of copper. Although the thermal conductivity of aluminum is lower than that of copper. It is only 60% of copper, but due to the existence of a tin protective layer with a lower thermal conductivity in the copper heat sink, the thermal efficiency of the aluminum heat sink is higher than that of the copper heat sink. In addition, aluminum has good casting processability. Include aluminum framing system and aluminum curtain wall. Although the aluminum heat sink has the advantages of light weight, low raw material cost, and good heat dissipation performance, the poor welding process and large investment in production equipment are difficult to solve for a long time, which limits the wide application of the aluminum heat sink. It was not until the mid-1980s that the United States succeeded in manufacturing aluminum radiators using brazing processes, which enabled the modular production and application of aluminum radiators.
However, the poor corrosion resistance of aluminum radiators makes aluminum radiators difficult to use on heavy-duty trucks, construction vehicles and military vehicles that are in poor condition. Now extruded aluminium sections is very common.Domestic car radiators are still dominated by copper radiators, which are widely used only in small engines such as cars. We are also an aluminium extrusion suppliers. Since the introduction of the first aluminum water tank production line in 1992, China has introduced a number of production lines, starting with mechanical assembly and later introducing a brazing process line. However, compared with foreign countries, the overall production process is backward and production efficiency is low. Include aluminum framing system and aluminum curtain wall.
The aluminum profile has a density of only 2.7 g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83 g/cm3, 8.93 g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemicals, and many chemical systems.
Industrial aluminum profile are often chosen for their excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly twice that of copper.
Thermal conductivity rate
Aluminum alloys have a thermal conductivity of about 50-60% of copper, which is advantageous for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automotive cylinder heads and radiators.
Industrial aluminum profile are non-ferromagnetic, which is an important feature for the electrical and electronics industries. Industrial aluminum profile are not self-ignitable, which is important for applications involving handling or contact with flammable and explosive materials.
The machinability of the aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, and in various states after the production of these alloys, the machining characteristics vary considerably, which requires special machine tools or techniques.
The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the variation in allowable deformation.
Aluminum is extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from that of primary aluminum.
Q: What features Aluminum radiators have?
A: 1. Corrosion resistance: Aluminum alloy radiator on material surface can produce thick film solid oxide, which can be heated to pH < 9 in water or used in automobile water tank for a long time, and can be specially treated by using aluminum radiator surface. We are also an aluminium extrusion suppliers. It can be used for a long time in materials with pH < 12 and has a longer shelf life.
2. Beautiful and generous: Radiator aluminum can be used for various surface treatments, various colors and seamless, decoration, beautiful and durable, selective, can meet people's personalized needs. Now extruded aluminium sections is very common.
3. Safety: The bigger the specific resistance of aluminum alloy radiator is, the higher the specific stiffness is than that of copper and steel cast iron. Even in the case of thinner thickness, it can withstand enough pressure without handling, damage bending strength, tensile strength and impact strength during installation and use. Include aluminum framing system and aluminum curtain wall.
4. Light weight: The weight of aluminum alloy radiator is one tenth of that of cast iron radiator. The sixth steel radiator and the third copper radiator can greatly reduce transportation costs, labor intensity and installation time. We are also an aluminium extrusion suppliers.
5. Easy to install and maintain: Low density of aluminum alloy radiator can be processed in various shapes and specifications of components, so that aluminum radiator has a large cross-section, and a conventional assembly, product, treatment surface can be a step, construction site can be installed directly, saving a lot of installation costs. Maintenance is also convenient and cheap. Now extruded aluminium sections is very common.
6. Energy saving: When the distance between the input and output aluminum alloy radiators is the same heat conduction temperature, the aluminum radiator is 2.5 times as large as the cast iron radiator. Because of its beauty, the heating cover can be omitted and the heat loss can be reduced. Over 30%, cost reduction more than 10%. Although the heat dissipation effect of aluminum radiator is slightly worse than that of copper radiator, the weight of aluminum radiator can be greatly reduced. Include aluminum framing system and aluminum curtain wall.
Q: What are the advantages of aluminum radiators?
A: The main advantages of the aluminum profile heat sink: good heat dissipation performance, low cost, easy processing, high power resistance to oxidation and corrosion, so the application is very extensive. Especially in the field of industrial electronics, many high-power devices will choose aluminum radiators. Now extruded aluminium sections is very common. Some special requirements can use heat pipe radiators, copper composite liquid cooling radiators, etc., but the two main bodies are aluminum radiators.
Q: What is the future development trend of profile radiators?
A: Radiator development so far, has been developed from the original cast iron radiator for light profile radiator. Light profile radiator is made of non-iron materials, compared with the original cast iron radiator from the appearance or quality have a great improvement, to meet the needs of people to improve the taste of life, by the consumer's favor. Below we look at the development trend of profile radiator together! At present, radiator presents the development characteristic of brand, systematization and simplicity. The brand consciousness of radiator industry is strengthened gradually. But most manufacturers are small in scale, low in production capacity and poor in technical level. But passed the development of 10 years again, a batch of brand manufacturer that scale is large, capacity is high, craft level is more advanced, product quality has assurance appeared inside radiator industry. Now, the consciousness that domestic radiator manufacturer builds independent brand is strengthened gradually, the disorganized condition of radiator market in the past also gets improvement gradually. Now extruded aluminium sections is very common. The development of modern science and technology brings a lot of convenience to people's life and industrial production. Radiator in heating application, is not only a single individual, heating work should be systematic. With the scientific management mode of home life and industrial production becoming more and more popular, radiator also needs systematic control and management. Radiator industry in the continuous improvement of technological level, but also constantly research and development system control, improve the scientific and technological content of the radiator. The technical level of foreign radiator should far exceed the level of our country radiator industry, these gaps are the direction that frequency converter radiator industry should develop in the future. Some large domestic radiator enterprises are committed to quality stability, design process, production automation and other aspects, narrowing the gap with foreign enterprises. In recent years, the radiator industry has formed a multi-material, multi-variety comprehensive development, especially aluminum, steel, steel and aluminum composite, copper and aluminum composite light radiator products such as rapid development, production technology has tended to mature, reliable quality. At present, there are nearly 40 enterprises specializing in the production of light heating radiators in China. Now, in the residential buildings of large and medium-sized cities, most of them adopt light radiators to meet the needs of consumers for beautifying their homes. Most manufacturers of light radiator products, basically reached the "safe and reliable, light, thin, beautiful, new" requirements. Include aluminum framing system and aluminum curtain wall.
The radiator shown above is an electronic aluminum insert. Electronic aluminum insert radiator is suitable for body heat dissipation, such as machine, computer host, router, circuit board, assembly lamp, charger and other devices. Aluminum alloy is selected as the material, which has corrosion resistance, high temperature and pressure resistance, and is not easy to rust in wet environment. We are also an aluminium extrusion suppliers. Include aluminum framing system and aluminum curtain wall. The surface is lustrous and glittering, with quality assurance, durable, and can be customized according to needs. Now extruded aluminium sections is very common.
The picture above shows the cold extrusion integrated radiator Advantages of Cold Extrusion Integrated Radiator Products
1. Excellent heat dissipation performanceA. The material of cold extrusion radiator is 1070 pure aluminum, the thermal conductivity is 226 M. k, the blade can be 0.7 thickness, and the thermal radiation surface area of the product can be increased.
2. Save product cost and improve product life
A. The cost of a product is lower than that of aluminum profile automotive products when the quantity of a product is large. At the same time, the conventional aluminum profile automotive products are lamp cup and lamp cap split type, and the cost of assembly labor needs to be increased to assemble them. Include aluminum framing system and aluminum curtain wall. We are also an aluminium extrusion suppliers.
B. Compared with conventional automotive radiators made of industrial aluminum profile and die-casting radiators made of aluminum alloys:
(1) The integral radiator with the same volume and shape can be used for the heat dissipation of higher power products (e.g. a conventional aluminum automobile radiator cup can only be used for the heat dissipation of 3W bulbs, while the integral radiator cup with the same shape and size can be used for the heat dissipation of 5W bulbs; and if the conventional radiator is used for the heat dissipation of 5W bulbs, it can be used for the heat dissipation of 5W bulbs. The cost will be much higher than the one-piece radiator if the volume is increased.
(2) If two cold extrusion radiators with the same volume and shape are used on the same power bulb, the accumulated temperature in the product with the integrated radiator will be greatly reduced, and the service life of the product will be greatly improved.
3. Excellent appearance and texture The surface of one-piece radiator can be anodized. The surface of die-casting products can’t be anodized, but can only be painted. Include aluminum framing system and aluminum curtain wall. We are also an aluminium extrusion suppliers. The paint may drop after a period of time because of thermal expansion and contraction of products. At the same time, the paint can also inhibit the radiation diffusion of heat, which affects both the appearance texture and heat dissipation. Now extruded aluminium sections is very common.
The picture above shows the sunflower radiator Sunflower radiator is a type of radiator, which is named because of its divergence. We are also an aluminium extrusion suppliers. At present, most of the solar radiators on the market are made of aluminium and copper plated. Since most of the solar radiators are equipped with cooling fans, the copper plating design can be used to improve the cooling effect. In the case of a slightly faster wind speed, the effect of aluminium copper-plated radiator will be higher than that of pure aluminium radiator, and the increase of air volume will help to heat dissipation. Include aluminum framing system and aluminum curtain wall.
The picture above shows the radiator shell of the vehicle. The vehicle radiator is made of aluminium alloy, which can greatly reduce the weight of the vehicle and effectively reduce the braking distance, making the vehicle more flexible in the process of steering and turning, and reducing the risk of collision. The high strength weight ratio of aluminium makes automotive parts keep light weight while carrying high load, and absorbs a large amount of energy generated by collision when subjected to impact, thus ensuring passenger's personal safety. Now extruded aluminium sections is very common. In addition, the corrosion resistance of aluminium can also minimize the possible damage to the body structure in the life cycle of the vehicle, and maintain the ability of the body to absorb collision energy for a long time and steadily.
