The present invention relates to a connection structure between a receiver dryer tank for an air conditioner and a condenser header to further improve connection workability.

In general, a cooling system used in automobiles is a compressor that compresses a gaseous refrigerant to high temperature and high pressure by using an engine power, and is connected to the outlet of the compressor to discharge heat of the refrigerant to the outside while passing the refrigerant at high temperature and high pressure. A condenser, a receiver dryer connected to the condenser to temporarily store and circulate the refrigerant, an expansion valve connected to the receiver dryer, and a refrigerant dryer connected to the expansion valve to cool the air in the vehicle while circulating the refrigerant therein. It consists of an evaporator.

The reason why the receiver temporarily stores and supplies the refrigerant is that the amount of refrigerant evaporated from the evaporator varies depending on the room temperature of the vehicle, so that the refrigerant supplied from the condenser is not supplied directly to the evaporator through the expansion valve. In order to respond flexibly to changes in situation, the tank is stored in a tank and supplied as needed.

On the other hand, the receiver dryer tank as described above is made by cutting the aluminum pipe that is extruded into a cylindrical shape to a certain length, the one side is sealed and the other side is fastened by the cap is configured to maintain the inside of the tank airtight.
