Abstract: A heat releasing unit includes heat releasing constituents which are stacked and are joined together while heat releasing flow passages are formed in the heat releasing constituents, respectively. An evaporating unit includes evaporating constituents which are stacked and are joined together, while evaporating flow passages are formed in the evaporating constituents, respectively. The evaporating unit and the heat releasing unit are arranged one after another in a direction along a side plate portion. A heat releasing unit outlet is formed at an outlet-side heat releasing constituent that is one of the heat releasing constituents placed at an end thereof. An evaporating unit inlet is formed at an inlet-side evaporating constituent that is one of the evaporating constituents placed at an end thereof. All of the heat releasing flow passages are connected to the evaporating flow passages through the heat releasing unit outlet and the evaporating unit inlet.

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.
