Variable frequency air conditioner and air conditioner outdoor unit radiator

Abstract

The invention provides an air conditioner outdoor unit radiator. The air conditioner outdoor unit radiator comprises a condenser, an outdoor electronic expansion valve, an outdoor unit liquid side stop valve, an evaporator set and an air-liquid separator which are sequentially communicated through an air conditioner pipeline, and an electronic control box for electronically controlling an outdoor unit. A heat radiation pipeline communicated with the inlet end of the air-liquid separator is arranged at the portion, between the outdoor electronic expansion valve and the outdoor unit liquid side stop valve, of the air conditioner pipeline, a module heat radiation device installed in the electronic control box is arranged on the heat radiation pipeline and comprises a heat radiation structure and a refrigerant pipeline communicated with the heat radiation pipeline, and the input end of the refrigerant pipeline is provided with a single-pass electromagnetic valve for controlling the refrigerant flow. The single-pass electromagnetic valve at the input end of the refrigerant pipeline controls the flow of refrigerant in the refrigerant pipeline, part of the refrigerant flows to the refrigerant pipeline to conduct heat radiation on the electronic control box, and the working stability of a compressor in a variable frequency air conditioner is guaranteed. The invention further provides the variable frequency air conditioner.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, and more specifically, relates to an inverter air conditioner and a cooling device for an outdoor unit of the air conditioner. Background technique [0002] There are a large number of electronic heating elements in the electric control box of the inverter air conditioner outdoor unit, and the inverter compressor drive module is the core and most important element in the electric control box of the inverter outdoor unit, and it is also the largest heating element. The module generates a lot of heat when the compressor is working. If the heat is not dissipated in time and kept within a reasonable range, the variable frequency drive module will usually be burned out. [0003] The electric control box of the traditional inverter air conditioner outdoor unit generally uses the negative pressure generated when the fan running on the outdoor unit rotates to flow the wind from the ins...

Problems solved by technology

The module generates a lot of heat when the compressor is working. If the heat is not dissipated in time and kept within a reasonable range, the variable frequency drive module will usually be burned out.

[0003] The electric control box of the traditional inverter air conditioner outdoor unit generally uses the negative pressure generated when the fan running on the outdoor unit rotates to flow the wind from the inside of the electric control box to take away the heat emitted by various electronic components, but this method is limited by The working environment of the outdoor unit of the inverter air conditioner and the influence of the outdoor ambient temperature, in some harsh environments, this heat dissipation method is not enough to take away the heat so that the most important heating element of the inverter air conditioner - the inverter drive module is maintained at a safe working temperature
