- connection member 300 is coupled to the end plate 200 corresponding to the opposite side where the receiver dryer 1200 is installed so that the external structure connected to the water-cooled condensing tooth does not interfere with the receiver dryer 1200. do.
- the heat exchanger core 1100 may include a flow path through which the cooling water flows and a flow path through which a fluid other than the cooling water flows, that is, a flow path through which a refrigerant flows, and the water-cooled condenser 1000 exchanges heat with the refrigerant and the cooling water to generate the refrigerant. It further includes a condensation region for condensing, in this case, the receiver dryer 1200 can separate the gas-liquid from the condensed refrigerant.
- the water-cooled condenser 1000 may further include a supercooling region for supercooling the refrigerant by exchanging heat with the refrigerant that has passed through the receiver dryer 1200 .
- the connector 1300 connects and fixes the heat exchanger core 1100 and the receiver dryer 1200 forming the condensing region and the subcooling region to each other.
- connection member for connecting the heat exchanger to the external part or fixing the external part to the heat exchanger without a separate welding process, thereby reducing the number of manufacturing processes in the production of the heat exchanger, thereby improving productivity and economic efficiency.
