Abstract: A flow path tube of a heat exchanger includes an inner fin having a meander shape in which a one-side top part and an other-side top part are alternately arranged via an intermediate part. The intermediate part includes a communication part with a communication port that communicates the adjacent fine flow paths. A one-side wall part is extended from the one-side top part, which is adjacent on one side, to the communication part and separates the adjacent fine flow paths. An other-side wall part is extended from the other-side top part, which is adjacent on the other side, to the communication part and separates the adjacent fine flow paths. An edge of the one-side wall part is formed such that an edge of the other-side wall part is shifted in parallel in the longitudinal direction of the flat cross sectional shape of the flow path tube.

Abstract: A stacked heat exchanger includes: passage tubes stacked with each other to support a heat exchange object, a passage being defined in the passage tube for a heat medium to exchange heat with the heat exchange object; and a pipe connected to one of the passage tubes located at one end in a stacking direction of the plurality of passage tubes. Each of the passage tubes has a protruding pipe portion protruding in the stacking direction and communicating with the adjacent passage tube in the stacking direction. The one of the passage tubes located at the one end in the stacking direction is an in/out passage tube. The pipe has a surface at one end in a longitudinal direction of the pipe, and the surface intersects the longitudinal direction of the pipe and is joined to the in/out passage tube.

Abstract: A stacked heat exchanger includes a first passage tube and a second passage tube that are included in a plurality of passage tubes stacked in a stacking direction. The first passage tube has a first projecting pipe, and the second passage tube has a second projecting pipe. The second projecting pipe has a fitted portion fitted into an inner side of the first projecting pipe, and is connected to the first projecting pipe such that the refrigerant can flow therethrough. The first projecting pipe has a joined portion joined to the fitted portion on a radially outer side of the fitted portion. The joined portion has an outer circumferential surface and an end of the first projecting pipe. The outer circumferential surface of the joined portion extends in the stacking direction to the end along an outer circumferential surface of the fitted portion.

Abstract: A cooling module has a heat generating body, a heat exchanger made of metal, and an insulating plate. The heat generating body has a heat dissipating surface. The heat exchanger has cooling surface facing the heat dissipating surface. The insulating plate has a first surface and a second surface. The insulating plate is interposed between the heat dissipating surface and the cooling surface on a condition that the insulating plate faces the heat dissipating surface and that the second surface faces the cooling surface. The insulating plate and the cooling surface are joined to be one body by a joining material. The heat dissipating surface and the insulating plate are in close contact with each other through an elastic member. The heat dissipating surface and the cooling surface are thermally connected to each other through the joining material, the insulating plate, and the elastic member.

Abstract: A cooler module has a cooling tube and a support member. The cooling tube has a first protruding tube portion and a second protruding tube portion. The first protruding tube portion is provided with a first flexible portion formed in an annular shape. The second protruding tube portion is provided with a second flexible portion formed in an annular shape. The support member has a first fitting portion fitted to the first protruding tube portion and a second fitting portion fitted to the second protruding tube portion. The support member supports a longitudinal center portion of the cooling tube on a condition that the first protruding tube portion and the first fitting portion are fitted together, the second protruding tube portion and the second fitting portion are fitted together, and the first flexible portion and the second flexible portion are recessed toward an inside of the cooling tube.
