Abstract: A heat exchanger includes tubes and a header tank. The tubes are arranged in parallel with each other, and fluid flows in the tubes. The header tank is disposed at end portions of the tubes in a longitudinal direction of the tubes and extends in a direction in which the tubes are arranged in parallel with each other to communicate with the tubes. The header tank includes a core plate, a resin tank main body part, and a resiliently-deformable sealing member. The tubes are joined to the core plate. The tank main body part is fixed to the core plate. The core plate includes a receiving part at which the sealing member is disposed. The tank main body part is fixed to the core plate with the sealing member clamped between an end part of the tank main body part on the core plate-side and the receiving part. The receiving part is disposed on a farther side from the tubes in the longitudinal direction of the tubes than the end portions of the tubes in the longitudinal direction of the tubes.

Abstract: A heat exchanger includes a plurality of cooling plates, a duct plate disposed around the cooling plates and a spacer plate fixed to both the duct plate and the cooling plate to prevent supercharged air from flowing into a gap between the duct plate and the cooling plate. The cooling plate includes cup portions allowing cooling water flow paths of the corresponding two cooling plates to be in communication with each other when the cooling plate is fixed to the adjacent cooling plate. The cooling water flow path formed in the cooling plate includes flow path portions and formed extending in a direction perpendicular to a flow direction of supercharged air from the corresponding cup portions. The cup portions are each formed in a tubular shape having a central axis at a position offset along the flow direction of the supercharged air from a center of the corresponding one of the flow path portions in a flow path width direction.

Abstract: A fin according to the present disclosure is a corrugated fin formed of a metal plate by bending into a corrugated shape, and the corrugated fin includes peak portions extending in a first direction, valley portions extending in the first direction, and inclined portions connecting the peak portions and the valley portions adjacent to each other. The peak portions and the valley portions are alternately arranged in a second direction perpendicular to the first direction, and a thickness of the metal plate at each apex of the peak portions and the valley portions is larger than a thickness of the inclined portions of the metal plate.

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.

Abstract: A heat exchanger includes a duct, a stacked core, and a coupling plate. The duct includes a first plate that is disposed to face at least one of end faces of the stacked core in a core width direction, and a second plate that is disposed to face at least one of the end faces of the stacked core in a tube stacking direction. The second plate includes a second-plate end plate portion disposed to face the end face of the stacked core in the core width direction and brazed to a wall surface of the first plate, a second-plate center plate portion that is disposed to face the end face of the stacked core in the tube stacking direction, and a flange portion that extends in the tube stacking direction and is brazed to a bottom wall surface of a groove portion of the coupling plate.

Abstract: A heat exchanger includes a duct, a core accommodated in the duct and exchanging heat between a first fluid and a second fluid, a tank having a protrusion protruding outward from an edge portion, and a crimping plate. The crimping plate includes an opposing wall facing an edge of the tank adjacent to the duct, and an outer wall extending from an outer circumference of the opposing wall. The opposing wall or an inner circumference of the opposing wall is joined to the duct and fixes the tank. The protrusion includes a surface facing in a direction angled toward the inner space from a direction in which the outer wall extends from the opposing wall.
