What Is An Aluminum Heat Sink?

Whether for a large number of industrial equipment or for the personal computers used in our study, in order to enable them to work normally in the hot summer, aluminum heat sinkreally plays an important role. First of all, aluminum heat sinkis also called radiator aluminum profile or sunflower aluminum profile. Aluminum heat sink has the characteristics of beautiful appearance, light weight, good heat dissipation performance, good energy saving effect and so on. The surface of the processed aluminum heat sinkis treated by anodizing, which can increase the corrosion resistance, wear resistance and appearance of aluminum. At present, the types of aluminum heat sinkcommonly used in China are as below: electronic aluminum heat sink, electrical aluminum heat sink, computeraluminum heat sink, sunflower aluminum heat sink, power semiconductor aluminum heat sinkand so on. Aluminum heat sinkis widely used in machinery, automobile, wind power generation, construction machinery, air compressor, railway locomotive, household appliances and other industries because of its superior performance.


There are two kinds of aluminum heat sink: high pressure cast aluminum and tensile aluminum alloy welding. The main advantages of aluminum heat sinkare as follows: firstly, the heat dissipation of aluminum heat sinkis good, and the characteristics of energy saving are very obvious. In the same room, if you use the same size of aluminum heat sink, the number of aluminum sheets is less than that of steel. Aluminum heat sinkhas good oxidation corrosion resistance and does not need to add any additives. The principle is that once aluminum encounters oxygen in air, it forms an oxide film, which is tough and compact, which prevents further corrosion of bulk materials. As to select aluminum heat sink, it is best to select high pressure cast aluminum module combined heat sink. The aluminum heat sinkis molded by integral die casting, so there is no weld leakage problem. And its biggest advantage is that the product is not limited by the district heating system. Even in an open boiler system, it is free from oxygen corrosion. Because it adopts module combination design, if it is found that the indoor temperature is not enough after a heating season, one or two more pieces can be installed in the second year to meet their own needs, without having to replace the whole set of heating as a steel radiator. In addition, because the water quality requirements of aluminum heat sinkare different from those of steel, the mixed installation of aluminum heat sinkand other materials should be avoided.


It is well known that aluminum, as the most abundant metal element in the earth’s crust, has amazing reserves on Earth. In recent years, with the continuous progress of metallurgical technology, the development and utilization of aluminum is constantly improving. As a kind of device for heat dissipation, the application range and scene of aluminum heat sinkare extensive at present. Behind the popularity, it highlights the natural advantages of aluminum heat sink. For your information, at present, in the cooling types of equipment, the most common heat dissipation scheme is to adopt the aluminum heat sinkfor air-cooled solution.
