What is the main cooling method of micro cooling fan?
There are two types of heat dissipation: passive cooling and active cooling. In active cooling, it can be divided into air-cooled heat dissipation, water-cooled heat dissipation, liquid-cooled heat dissipation, heat pipe radiator heat dissipation, semiconductor refrigeration chip heat dissipation, compressor auxiliary heat dissipation, and liquid nitrogen heat dissipation according to the adopted heat dissipation method. The working principle of the cooling fan is realized based on energy conversion, that is, electrical energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit principle is generally divided into various forms, and the performance of the fan will vary according to the circuit used. At the same time, cooling fans are widely used due to their fast speed, easy installation and good cooling effect.
The heat dissipation method of the micro cooling fan refers to the main way for the heat sink to dissipate heat. In thermodynamics, heat dissipation is heat transfer. There are three main ways of heat transfer:
1. thermal radiation: refers to the transfer of heat through radiation, the most common is solar radiation.
2. Thermal convection: Refers to the heat transfer method of a cooling fan that is used by a flowing fluid (gas or liquid) to transfer heat to a tropical area. The "forced convection" cooling mode used by cooling fans to drive airflow is more common in chassis cooling systems.
3. heat conduction: heat convection and heat radiation. This is the most common heat transfer method for cooling fans. In short, when a substance itself or a substance comes in contact with it, the transfer of energy is called heat transfer. For example, the way in which the CPU heat sink base directly contacts the CPU to take away heat is heat conduction.
