ABSTRACT:
A heat exchanger includes a tank and a base plate, and each of the tank and the base plate is formed in a box shape having a U-shaped cross-section. The tank is connected to the base plate to close an end portion of an opening side of the tank using the base plate. Protrusion portions are provided inside a folded portion of the base plate in a lateral direction to be opposite to connection portions of first and second folded portions of the tank. Further, ribs are provided in the folded portion of the base plate in the lateral direction to increase stiffness of the base plate in a longitudinal direction thereof. Thus, connection portions of the tank and the base plate can be securely brazed.
