Claims

[Claims for Utility Model Registration] (1) A heat exchanger body is formed by stacking tube elements and fins in an alternating arrangement, each having a communicating tank portion at the end, and the outer surface of the outermost tube element. In the laminated heat exchanger provided with a header that communicates the tank section and the refrigerant inlet pipe or the refrigerant outlet pipe, the connection part of the header with the tank part is formed with a rectangular cross section, while the refrigerant inlet pipe Alternatively, a stacked heat exchanger characterized in that a connecting portion with a refrigerant outlet pipe is formed with a circular cross-section and is offset toward the inside of the heat exchanger body with respect to the connecting portion having a rectangular cross-section. (2) The header is formed by deforming one end of a square pipe with a thick wall on one side into a circular cross section by stretching the thick wall in the pipe expansion direction. Stacked heat exchanger as described in section.
