Abstract: A heat exchanger includes a plate member, a fixation member, and a brazing material pathway. The plate member has a first side coated with a brazing material, and a second side which is an opposite side of the first side and is not coated with the brazing material. The fixation member is disposed on the second side and configured to fix a position of a pipe. The brazing material pathway extends from the first side to the second side. The brazing material coated on the plate member spreads into the brazing material pathway. The pipe is inserted into an insertion hole formed in the plate member. An entire outer circumference of the pipe is swaged and engaged with an inner side of the insertion hole. The brazing material pathway is formed on at least the outer circumference of the pipe or the inner side of the insertion hole.

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 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.

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 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 crimping plates fixed to an inlet and an outlet of a duct and having frame shapes corresponding to opening shapes of the inlet and the outlet. Each of the crimping plates includes a beam connecting two different positions on an inner periphery of the crimping plate. The beam has a rib.
