Conduction heat dissipation
It refers to a way in which the heat of a heat source is directly transmitted or transmitted through the thermal conductive medium in contact with it to achieve heat dissipation.
For example, CPU heat dissipation is achieved by fitting the CPU and heat dissipation module with a thermal conductive silicone gasket, thereby transferring heat from the CPU to the heat dissipation module more quickly and reducing CPU temperature.
Radiative heat dissipation
The dissipation of heat from the body in the form of thermal rays to objects with lower temperatures around it, i.e. in low-temperature air, is called radiative heat dissipation. This is the main cooling method in a quiet state, influenced by the ambient temperature.
For example, CPU heat dissipation, the CPU transfers heat to the heat dissipation module through a thermal conductive silicone gasket, and the heat dissipation module then carries the heat to the relatively low temperature air through radiation heat dissipation.
Convective heat dissipation
A heat dissipation method that achieves heat dissipation through the flow of air.
For example, the cooling fan in a computer blows out heat from the computer and brings in cold air, increasing air flow to achieve better heat dissipation.
Evaporative heat dissipation
A way for water to dissipate heat by evaporating at high temperatures.
For example, when a person is sweating and sweat evaporates, it absorbs heat from the skin to keep the body temperature from rising
