[0002] The condenser and evaporator in the car air conditioner are collectively called heat exchangers. The evaporator is a heat exchanger. The high-pressure liquid refrigerant enters the evaporator through the expansion valve. Due to the atomization of the expansion valve, the liquid refrigerant becomes mist. The mist refrigerant is converted into gas under low pressure conditions. During the conversion process, it absorbs heat to achieve the result of refrigeration. The function of the condenser is to cool the high-temperature and high-pressure gas discharged from the compressor and convert it into high-pressure and low-temperature liquid.

In addition, the traditional clamp is inconsistent with the outer shell material of the drying bottle, and electrochemical corrosion will occur between them, affecting the service life of the condenser. The shell wall thickness of the integrated drying bottle is relatively thick, heavy, and inconvenient to use. For example, a Chinese patent discloses "a heat exchanger drying bottle connection structure", and its application number is: "CN202121661930.3", which includes: a drying bottle and a collecting pipe, the drying bottle and the collecting pipe are respectively fixed on the side end surface of the heat exchanger and are arranged perpendicular to each other, the drying bottle is connected to the collecting pipe through a liquid outlet pipe, and a connecting block is fixed at the end of the drying bottle, and a liquid inlet channel is formed on the end surface of the connecting block.
