Heat dissipation device for air conditioner, air conditioner and control method of air conditioner

Abstract

The invention discloses a heat dissipation device for an air conditioner, the air conditioner and a control method of the air conditioner. The air conditioner is provided with an electric control device. At least one part of a heat dissipation device is located at the electric control device to dissipate the heat of the electric control device. The heat dissipation device comprises a heat pipe. The heat pipe is provided with an evaporation section and a condensation section. At least one part of the evaporation section is located at the electric control device. A cooling assembly comprises a liquid cooling assembly and / or an air cooling assembly. The liquid cooling assembly is located at the condensation section and conducts heat exchange with the heat pipe through the cooling liquid. Theair cooling assembly is located at the condensation section and conducts heat exchange with the heat pipe through the air flowing. According to the heat dissipation device, the heat dissipation efficiency of the heat dissipation device on the electric control device can be improved. The heat dissipation and the cooling of the electric control device are accelerated. The reliability of the air conditioner is improved, and the service life of the air conditioner is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cooling device for an air conditioner, an air conditioner and a control method thereof. Background technique [0002] In related technologies, for a heat pump air-conditioning system, as the power load increases, the core electronic control components of the system generate more heat, while the electronically controlled heating components of the air-conditioning system are relatively concentrated. For example, the power module of the compressor as the main heating element Increased compressor frequency increases heat generation. Under high ambient temperature, the traditional air-cooled heat dissipation is often not enough to remove this part of the heat, causing the temperature of the electronic control device of the air conditioning system to rise continuously and exceed the normal operating range, which is not conducive to the efficient work of the electronic contro...

Problems solved by technology

Under high ambient temperature, the traditional air-cooled heat dissipation is often not enough to remove this part of the heat, causing the temperature of the electronic control device of the air conditioning system to rise continuously and exceed the normal operating range, which is not conducive to the efficient work of the electronic control device. It may even cause damage to electronic control components, which will affect the service life of the air conditioning system to a certain extent
