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. In a fin separating step W4, the fins in the connected state of the respective heat exchangers are separated from each other in the parting portion. 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.
