Abstract
A heat exchanger includes a duct, a core portion, and a caulking plate. The duct has an inlet and an outlet. The core portion is housed in the duct in a state where cooling plates and cooling fins are stacked in a stacking direction. The caulking plate has a frame shape corresponding to an opening shape of the inlet and the outlet and brazed to the inlet and the outlet. The caulking plate is interposed between the duct and a tank to fix the tank. A first joint between the duct and the core portion and a second joint between the duct and the caulking plate are distanced from each other in the stacking direction by a predetermined distance. The duct has a rib between the first joint and the second joint or at the second joint.
