Further, a receiver drier for temporarily storing the refrigerant liquefied in the condenser and supplying the refrigerant to the evaporator as needed according to the refrigeration load is provided in the condenser. When the load of the evaporator is changed, the flow of the refrigerant is required to be changed correspondingly; when there is a small amount of refrigerant leakage, make-up refrigerant is required.

Specifically, the receiver-drier includes a barrel and a bottom cover disposed at the bottom of the barrel, wherein the bottom cover is used for sealing the bottom of the barrel. For the existing receiver-drier, the bottom cover is generally made of a double-faced composite board. When the bottom cover is installed, the bottom cover is usually inserted into the cylinder through an opening at the side part of the cylinder, and then is contacted with the inner wall of the cylinder and is connected with the inner wall of the cylinder through brazing. However, in this structure, since the composite material in the bottom cover is used as a solder for connecting the bottom cover and the inner wall of the cylinder, the molten composite material is required to enter between the bottom cover and the inner wall of the cylinder by capillary action during soldering, so that cold joint is easily caused. As a result, it affects the function of the product and the first pass rate of the product, requires rework of the product and even direct scrapping, and increases the actual manufacturing cost of the product.
