Automatic reversing device suitable for liquid cooling module of air conditioner and air conditioner comprising same

Abstract

The invention provides an automatic reversing device suitable for a liquid cooling module of an air conditioner and the air conditioner comprising the same. The automatic reversing device comprises a main valve body (1) provided with an internal cavity. A plurality of pipelines communicating with the internal cavity are formed on the main valve body (1). The automatic reversing device further comprises a switching device allowing the multiple pipelines to communicate with one other and enabling the pipelines to be automatically switched in different communicating modes, so that one pipeline of the multiple pipelines is located at the fluid upstream end of the main valve body (1) all the time, and another pipeline is located at the fluid downstream end of the main valve body (1) all the time. The function of automatically reversing airflow flowing through the automatic reversing device can be achieved, the device can be effectively applied to the part of the liquid cooling module of the air conditioner, and the liquid cooling module can further be made to be located on the upstream of a throttling device all the time, so that the conditions that liquid cooling module is cooled by a low-temperature coolant to be lower than the environment dew point temperature and consequently condensation of the liquid cooling module is caused and condensation of the cooling part is also caused are avoided.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an automatic reversing device suitable for a liquid cooling module of an air conditioner and an air conditioner with the same. Background technique [0002] The air conditioner in the prior art requires a dedicated drive controller to drive the operation of the compressor or motor. When the compressor or motor is running, the module of the drive controller will generate heat. If this part of the heat cannot be dissipated in time, it will cause The temperature of the module continues to rise, causing damage to the module. At present, there are two cooling methods for the air conditioner on the drive controller (or drive board), which are air cooling and liquid cooling. When choosing a cooling method, the cooling load of the drive board and the structure of the whole machine are mainly considered. The air-cooled module uses the outdoor air flow for cooling. Th...
