The working principle of the cooling fan is achieved by energy conversion, that is, electric energy, electromagnetic energy, mechanical energy and kinetic energy. The circuit principle is generally divided into many forms, and the performance of the fan varies with different circuits. At the same time, the cooling fan has the characteristics of fast speed, convenient installation and good cooling effect, and has been widely applied. In order to make everyone have a better understanding of the cooling fan, what are the main cooling methods of the cooling fan introduced in today's small edition?

　　
　　The heat dissipation mode of the cooling fan is the main way to dissipate heat of the radiator. In thermodynamics, heat dissipation is heat transfer, and there are mainly three ways of heat transfer.　　
　　One、Thermal radiation：It refers to the transfer of heat by radiation. The most common form of solar radiation is solar radiation.　　
　　Two、Thermal convection：It refers to the flow of fluid (gas or liquid) to heat the heat transfer mode of the heat fan in the tropics, and in the cooling system of the chassis more common is the "forced heat convection" of the fan to drive the flow of the gas.　　
　　Three、Heat conduction：Thermal convection and thermal radiation. This is the most common heat transfer mode of the cooling fan, which is simply the matter itself or when the material is in contact with the substance, the transfer of energy is called heat conduction. For example, the way that CPU heat sink base contacts directly with CPU and takes away heat is heat conduction.
