3 Heat-dissipating Methods of DC Cooling Fan
Because the factory needs to increase equipment, it is necessary to purchase various types of machinery. Extending the service life of machinery and equipment has become a key issue. The technology and performance of cooling fans have fully reached the mature stage. It can effectively reduce the working environment temperature and prolong the life of the equipment.
The working principle of cooling fans is realized through energy conversion, namely electrical energy, electromagnetic energy, mechanical energy and kinetic energy. The circuit principle is generally divided into various forms, and the performance of the fan varies with the circuit. At the same time, the cooling fan has the characteristics of fast speed, good cooling effect and convenient installation, and has also been widely used. In order to give everyone a better understanding of cooling fans, what are the main cooling methods of cooling fans? In this article, we will introduce in detail.
The heat dissipation mode of the cooling fan in ATO store 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.
- Thermal radiation. It refers to the transfer of heat by radiation. The most common form of solar radiation is solar radiation.
- 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.
- 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.
