Heat dissipating device of air conditioner frequency converter and frequency-conversion air conditioner

Abstract

The present invention provides a heat dissipating device of an air conditioner frequency converter and a frequency-conversion air conditioner. The heat dissipating device of the air conditioner frequency converter comprises: a vapor chamber which has a first surface embedded with a sintering heat pipe, wherein a vapor chamber area where part of pipe sections of the sintering heat pipe is laminatedwith a heating area on an electric control board of the air conditioner frequency converter to conduct heat generated by the heating area to the whole vapor chamber; and a cooling plate which has atleast partial areas being laminated with the second surface of the vapor chamber and is provided with a refrigerant pipe for refrigerant flow to employ the refrigerant and the vapor chamber for heat exchange. According to the scheme, the vapor chamber is employed to conduct high heat of the heating area on the electric control board to the whole vapor chamber, and low temperature of the cooling plate is employed to perform heat exchange with the vapor chamber to realize rapid temperature uniformity and effective heat dissipation of the frequency converter and allow the frequency-conversion airconditioner to be operated in a high-frequency mode in a condition of a very high environment temperature so as to improve a rapid refrigeration capacity in a high-temperature weather.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a cooling device for an air conditioner inverter and an inverter air conditioner. Background technique [0002] With the development of society and the improvement of people's living standards, air conditioners are more and more regarded as indispensable household appliances in life. Inverter air conditioners have gradually been widely promoted in the market due to their advantages of energy saving and low noise. [0003] The frequency converter installed on the outdoor unit is the core of the frequency conversion air conditioner. It operates at high frequency, cooling and heating up quickly; works at low frequency, maintains a constant temperature and realizes energy saving. However, there is a technical problem of heat dissipation in existing inverter air conditioners. Air conditioner inverters generally use Intelligent Power Modules (IPM for short) as inverter drive powe...

AI Technical Summary

Problems solved by technology

Due to the existence of high heat flux density, the conventional aluminum-fin radiator cannot effectively solve the heat dissipation, and the temperature on the surface of the heat source can reach 105°C. Affects the temperature of the surface of the heat source

The high temperature of the inverter limits its high-frequency operation, which makes the cooling capacity of the air conditioner insufficient, seriously affecting the performance of the air conditioner
