Abstract

A heat exchanger includes multiple aluminum heat transfer tubes through which a heat medium flows, and multiple aluminum connection pipes brazed to end portions of the heat transfer tubes. A heat equalizing member formed of a heat conductor is disposed to be in contact with at least two of the connection pipes and be capable of transferring heat therebetween. A method for producing the heat exchanger includes brazing the heat transfer tubes to the connection pipes in a state where the heat equalizing member is in contact with the at least two of the connection pipes.
