Dongguan Xunwang Hardware Products Factory reminds you that the heat dissipation method refers to the main way of dissipating heat from the radiator. In thermodynamics, heat dissipation is heat transfer, and there are three main ways of heat transfer: heat conduction, heat convection, and heat radiation. When the substance itself or when it comes into contact with matter, the transfer of energy is called heat conduction, which is the most common form of heat transfer. For example, the way in which the CPU heat sink base is in direct contact with the CPU to remove heat is heat conduction. Heat convection refers to the heat transfer mode of the flowing fluid (gas or liquid) to the tropics. In the heat dissipation system of the computer case, the "forced heat convection" heat dissipation method that drives the gas flow is more common. Thermal radiation refers to the transfer of heat by ray radiation, the most common of which is solar radiation. These three heat dissipation methods are not isolated. In the daily heat transfer, these three heat dissipation methods are simultaneous and work together. -

In fact, any type of heat sink basically uses the above three heat transfer methods at the same time, but the focus is different. For example, an ordinary CPU air-cooled heat sink, the CPU heat sink is in direct contact with the CPU surface, and the heat of the CPU surface is transferred to the CPU heat sink through heat conduction; the heat-dissipating fan generates airflow to remove the heat of the CPU heat sink surface through heat convection; The flow of air is also carried away by the heat convection to remove the heat from the air around the CPU heat sink until the outside of the chassis; at the same time, all the high temperature parts will radiate heat to the low temperature part. -Dongguan Xunwang Hardware Products Factory

The heat dissipation efficiency of the heat sink is related to the thermal conductivity of the heat sink material, the heat capacity of the heat sink material and the heat sink medium, and the effective heat dissipation area of ​​the heat sink.

According to the way to remove heat from the heat sink, the heat sink can be divided into active heat dissipation and passive heat dissipation. The former is usually an air-cooled heat sink, while the latter is commonly used as a heat sink. Further subdivided heat dissipation methods can be divided into air cooling, heat pipe, liquid cooling, semiconductor refrigeration, compressor refrigeration and so on.
