A heat exchanger includes a first part made of metallic core material and having a first connecting portion, and a second part made of metallic core material and having a second connecting portion for connection to the first connecting portion. At least one of the first part and second parts is covered with a brazing layer, and the first and second parts are connected to one another by melting the brazing layer after the first part and the second part are assembled. The first connecting portion includes a fitting concave portion, and the second connecting portion includes a fitting convex portion which is press fitted into the fitting concave portion. The first connecting portion and the second connecting portion have the metallic core material exposed to each surface thereof so that each metallic core material directly contacts with one another when the convex portion is fitted in the concave portion. In this way, it is possible to fix the first part with the second part temporarily with a simple method and without more time and expense than needed.
A heat exchanger comprising:
A connecting structure for connecting first and second parts each made of metallic core material and having respective first and second connecting portions for connection to each other, at least one of said first and second parts being partially covered with a brazing layer, said first connecting portion and said second connecting portion being connected to one another by melting said brazing layer after said first part and said second part are assembled, said connecting structure comprising:
