Heat dissipation module, electric appliance heat dissipation assembly and air conditioner

Abstract

The invention discloses a heat dissipation module, an electric appliance heat dissipation assembly and an air conditioner. The heat dissipation module is composed of a fixing plate, a multiphase heat transfer assembly and a packaging layer. A first multiphase heat transfer piece is bent to form an evaporation section and a condensation section, and the evaporation section and the condensation section are fixed to the fixing plate in a penetrating mode, so that the evaporation section and the condensation section are attached to the two side faces of the fixing plate correspondingly. A second multiphase heat transfer piece is fixed on the second side surface of the fixing plate and is arranged opposite to the evaporation section. When the heat dissipation module is applied to heat dissipation, an evaporation side is connected with a power element, heat dissipated by the power element enables the temperature of the evaporation section to rise, the temperature of the initial condensation section is low, the heat resistance of the multiphase heat transfer assembly is large, the heat transfer efficiency is low, the temperature can be controlled above the dew point temperature, and condensed water is avoided. As the temperature rises, the heat resistance of the multiphase heat transfer assembly is reduced, and the multiphase heat transfer assembly and the fixing plate transfer heat simultaneously, so that it is effectively ensured that the heat of the power element is quickly dissipated, it is ensured that the temperature of the power element meets the design requirement all the time, and the reliability of a refrigerant heat dissipation mode is improved.

However, with the continuous development of component integration, power consumption has increased significantly, and air-cooled heat dissipation can no longer meet the temperature rise and life requirements of electrical boxes. At the same time, efficient and reliable air-cooled Road design will also be limited by space. The principle of the refrig...
