Abstract: In a fin forming step, fins of heat exchangers are formed into a connected state where the fins are connected to each other via a parting portion. In a fin attaching step, the fins in the connected state are temporarily attached to the respective heat exchangers. In a fin fixing step, an integrated heat exchanger in which the fins are temporarily attached is passed through a heating oven to braze the fins to the respective heat exchangers.

Therefore, each of the heat exchangers can independently perform a heat exchanging operation without being affected by heat conduction from the other heat exchanger via the fins.

Abstract: In a heat exchanging apparatus for a vapor compression refrigerant cycle, an internal heat exchanger is attached to an end of a radiator. The internal heat exchanger is arranged such that high-pressure refrigerant passages are closer to the radiator than low-pressure refrigerant passages. The heat exchanging apparatus can be mounted on a vehicle such that the radiator receives cooling air more than the internal heat exchanger. Because the internal heat exchanger performs heat exchange between high-pressure refrigerant and low-pressure refrigerant, performance of the internal heat exchanger is not degraded even if it is located at a part receiving less cooling air. Thus, the heat exchanging apparatus is easily mounted on a vehicle by integrating the internal heat exchanger with the radiator, without reducing a cooling capacity of the radiator.
