Description

Technical Field

[0002] The air conditioner compressor driver board will generate a certain amount of heat when working, especially under high load or high temperature environment. If this heat cannot be effectively dissipated, it will cause electronic components to overheat and even damage the circuit board. A common solution is to install a heat sink or radiator on the compressor driver board. The heat sink is usually made of metal and is directly installed on components with more concentrated heat, such as power transistors or integrated circuits. The radiator conducts heat to a larger surface area through thermal conductive materials to improve the heat dissipation efficiency.
