Problems solved by technology

[0002] For high-power electronic control devices, key components such as the inverter module and rectifier module of the electronic control device will generate a lot of heat during operation, and effective cooling is required to ensure the stability of the electronic control device. In related technologies, refrigeration systems are used The refrigerant cooling method in the system cools the electronic control device. The low-temperature and low-pressure refrigerant passes through the cooling device connected to the electronic control device and returns directly to the compressor. The cooling effect is good, but there is condensation when the electronic control device generates less heat. risk, additional dehumidification device is required, which complicates the structure of the electric control device, thereby increasing the cost of the electric control device

Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger, an outer machine throttle valve, an inner machine throttle valve, a first throttle valve, a second throttle valve, a cooling device and a heat exchanger assembly, wherein the compressor is provided with an exhausting port and an air return port; the first throttle valve is connected with the second end of the outer machine throttle valve and the second throttle valve; the second throttle valve is connected with the air return port; the cooling device is used for cooling an electrical controlling device and is in series connection between the first throttle valve and the second throttle valve; and the heat exchanger assembly comprises a first part and a second part, wherein the first part is in series connection between the cooling device and the second throttle valve, and the second part is in series connection between the second throttle valve and the air return port. According to the air conditioner, not only is the cooling requirement of the electric controlling device guaranteed, but also the condensation phenomenon on the surface of the cooling device is avoided, the structure of the electric controlling device is simplified, and cost is reduced.
