摘要： To eliminate a fear of electrolytic corrosion even in the case where a heat exchanger to be connected to the outside of the plate-type heat exchanger has a copper piping, and to prevent any damage from being given to the brazed portions of the plate-type heat exchanger at the time of joining pipes and to prevent faults from being generated in joined portions. An intermediate pipe made of a material in which the value of polarization potential becomes lower than that generated between a body of the plate-type heat exchanger and the copper piping is interposed between the plate-type heat exchanger body and the copper piping. Further, the plate-type heat exchanger body is disposed in a position out of a vertical line of a joined portion between the copper piping and the intermediate pipe. Further, a joint constituted by an intermediate pipe and a copper pipe joined in advance through brazing or welding at a temperature higher than a temperature of brazing of the plate-type heat exchanger body is brazed at the same time of brazing of the plate-type heat exchanger body under the condition that the joint is arranged so that the intermediate pipe side of the joint is joined with the end plate of the heat exchanger body.
