HEAT EXCHANGER AND REFRIGERATING CIRCUIT USING THE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger and a refrigerating circuit using the heat exchanger excelling in productivity and heat exchange performance with extremely simple countermeasures for preventing electric erosion caused by dissimilar metal contact. SOLUTION: This heat exchanger 1 is constituted by joining a first pipe member 2 (e.g. a capillary tube) and a second pipe member 3 (e.g. a suction pipe) formed of adjoining dissimilar metal by a brazing filler metal 4 and covering outer peripheries of the first pipe member 2 and the second pipe member 3 continuously with the brazing filler metal.
