The heat dissipation method of an air cooler refers to the primary method by which the air cooler dissipates heat. In thermodynamics, heat dissipation is heat transfer, and there are three primary methods of heat transfer: thermal conduction, thermal convection, and thermal radiation. Matter itself or when matter comes into contact with matter.
The transfer of energy is called heat conduction, which is a common method of heat transfer. For example, the method of directly touching the CPU heat sink base and the CPU to remove heat belongs to thermal conduction. Thermal convection refers to the method of transferring heat from a moving fluid (gas or liquid) to a tropical zone.
A common method in the cooling system of computer cases is the "forced convection" cooling method, which uses a cooling fan to drive gas activity. Thermal radiation refers to the transfer of heat through radiation, with solar radiation being commonly seen in daily life. These three methods of heat dissipation are not isolated. In daily heat transfer, these three methods of heat dissipation work together.
In fact, almost all types of air heat exchangers will use the above three heat transfer methods together, with different emphasis. For example, in a typical CPU air heat exchanger, the CPU heat sink touches the surface of the CPU directly, and the heat from the surface of the CPU is transferred to the CPU heat sink through thermal conduction.
