ABSTRACT:
A heat exchanger reduces a production of scrap portions and does not use a claw bending process at a time of forming a tank and a base plate. Each of the tank and the base plate is formed in a box shape having a U-shaped cross-section. The tank is joined to the base plate to close an end portion of an opening side of the tank using the base plate. A tube is inserted into a hole made at the base plate and fixed thereat in such a manner that the tube communicates with an inside of the tank. Each of the tank and the base plate is formed by folding an unfolded metal plate in which the box shape having the U-shaped cross section is in an unfolded state and joining a folded portion of the unfolded metal plate by brazing. According to the above configuration, the tank and the base plate can be structured by folding unfolded plates and by connecting the folded portions.
