The service life and performance of the cooling fan are closely related to the materials it uses.Materials directly affect the use effect of the cooling fan.Manufacturers pay special attention to the body materials and their performance when producing cooling fan products, among which, they pay special attention to three aspects:thermal conductivity, ductility and easy access.

First of all, the thermal conductivity, which is a particularly critical parameter of the cooling fan, is also one of the important bases that influence the selection of the body material of the fan.compared with other solid materials, the thermal conductivity of metal determines that it is more suitable for the manufacture of radiators.For example, aluminum dissipates heat faster and copper conducts heat faster.These characteristics are based on the characteristics of metal itself.

After all, the cooling fan is in contact with the high-temperature working environment, which requires sufficient cooling.Therefore, manufacturers will use materials with good thermal conductivity as much as possible when manufacturing cooling fans, which will help the cooling fans to work in high temperature environment.

Secondly, it is ductility, which refers to whether the material needed to manufacture the cooling fan can be processed into other shapes.Based on this consideration, the material needs to be relatively stable at high temperature and can be processed by various processing technologies.If it takes a lot of time and energy to melt and pour raw materials to manufacture a cooling fan, the result will not be worth the cost and increase the cost.Therefore, the materials selected by manufacturers for manufacturing cooling fans need to have good ductility and be conducive to manufacturing and processing.

Furthermore, materials are easily available, such as materials with good thermal conductivity.Some materials are rare, and some can be seen everywhere.Because manufacturers manufacture cooling fans on a large scale, the choice of required materials is concentrated in relatively common materials suppliers that do not need special processing procedures, so the price cost will be relatively lower, so that enterprises can reduce the cost.

According to the above three points, the material type of the heat sink can be determined.However, in addition to considering the thermal conductivity, it is also necessary to observe the mechanical properties and price cost of materials.

Gold and silver with high thermal conductivity can not be widely used because of their soft texture, too high density and too expensive price.After all, heat dissipation fans need mass production.Considering the cost and benefit, it is not realistic to use expensive metals.Because the thermal conductivity of iron is too low, it can't meet the performance requirements of high heat density occasions, and it is not suitable for making air cooling fins.The thermal conductivity coefficient of copper is also very high, which may be due to unfavorable conditions such as insufficient hardness, higher density, slightly higher cost and difficult processing.However, with the improvement of performance requirements of heat dissipation equipment in some fields, more and more radiator products are partially or completely made of copper.As a metal with higher content in the earth's crust, aluminum is favored because of its high thermal conductivity, low density and low price.However, the hardness of pure aluminum is relatively small, so it is obviously unrealistic to use it to make the body.

Therefore, in various application fields, manufacturers usually add other elements to make aluminum alloy.However, aluminum alloys with different element formulas have different characteristics, so they become the choice of processing materials for cooling fans.

After 33 years' deep cultivation of cooling fans, Taiwan Province Sanju Motor pays special attention to the performance of materials, product quality and service life in manufacturing.It doesn't cut corners and cost.Instead, it uses high-quality materials to ensure stable quality, strict inspection, and layer-by-layer checks, so that the cooling fans can truly exert their outstanding performance.
