1. "Small Cooling Fan" heat conduction, convection and thermal radiation. When the substance itself or the substance in contact with the material, the transfer of energy is called the heat conduction, which is the most common form of heat transfer. For example, CPU heat sink base in direct contact with the CPU heat away way belongs to the heat conduction.
2. "Small Cooling Fan" thermal convection: refers to the flow of fluid (gas or liquid) heat transfer method tropical walking in the computer chassis cooling system is more common cooling fan driven by the flow of gas, "Forced convection "cooling mode.
3. "Small Cooling Fan" thermal radiation: Refers to rely ray radiation heat transfer, the most common is the daily solar radiation. The three cooling methods are not isolated, in the daily heat transfer in the heat of these three ways are simultaneously, work jointly.
