A header-tank assembly (100a) includes a tank (10a), a gasket (20a) and a header (30a). The tank (10a) includes a plurality of first engagement elements (12a) configured thereon. The gasket (20a) includes a plurality of second engagement elements (22a) configured thereon. The second engagement elements (22a) are complimentary to and engages with the first engagement elements (12a) to mount the gasket (20a) along a periphery of a foot portion (14a) of the tank. The header (30a) is crimped to the foot portion (14a) of the tank (10a) with the gasket (20a) disposed between the header (30a) and the foot portion (14a) of the tank (10a).

A heat exchanger includes: a heat exchange core portion; and a tank portion connected to the heat exchange core portion. The heat exchange core portion has a connection plate that surrounds a part of the tank portion from an outer peripheral side. The connection plate has slit-shaped openings arranged along an edge of the connection plate in a first direction. A part of the connection plate between each of the openings and the edge is deformable into a concave shape toward the tank portion. A part of the openings has a widened portion at both ends in the first direction. A width dimension of the widened portion in a second direction from the opening to the edge is larger than that of the other portion of the opening.

A heat exchanger in which a connecting part may be coupled to a header tank of the heat exchanger in the short term without using a separate coupling component before a brazing process is performed, and a coupling method of a connecting part thereof. The connecting part is coupled to a first header tank or a second header tank while surrounding a predetermined region of an outer peripheral surface of the first header tank or the second header tank, a region of the connecting part to which external force is locally applied being coupled to the first header tank or the second header tank while protruding together with the first header tank or the second header tank.

A liquid cooling radiator with impurities filtering includes a radiation fin module, a top cover and a bottom cover respectively enclosed at two opposite ends of the radiation fin module, liquid cooling heat dissipation pipes tightly inserted through the radiation fin module in communication between an enclosed top chamber in the top cover and an enclosed bottom chamber in the bottom cover for coolant circulation, and wire gauge filters individually mounted in the liquid cooling heat dissipation pipes for removing impurities from the circulating coolant and slowing down the flowing speed of the circulating coolant.

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.

A heat exchanger that performs heat exchange between a first fluid and a second fluid includes a first duct plate, a second duct plate, a flow path member, a caulking plate, an insertion projection, and a contact protrusion. The insertion protrusion protrudes from at least one of the first duct plate and the second duct plate toward the caulking plate, and is inserted into an insertion hole defined in the caulking plate. The contact protrusion protrudes from at least one of the first duct plate and the second duct plate toward the caulking plate, and is fixed to, and in contact with, a stopper wall of the caulking plate. A surface of the contact protrusion is in contact with a stopper plane wall when the contact protrusion is fixed to the frame member.

A heat exchanger for cooling intake air with a coolant is provided with a shell and first and second front faces, wherein one of the front faces is an inlet and the other an outlet for intake air. The shell has at least one coupling element disposed along a circumferential line of the shell that is spaced apart from the first front face by a predetermined distance. The shell has a port as an inlet or outlet for the coolant. The port is arranged at a spacing from the first front face. The spacing is larger than the predetermined distance. The shell has an insertion section between first front face and circumferential line. The shell has an internal duct system connected to the port for guiding the coolant into the insertion section. The coupling element can fixedly couple with at least one corresponding coupling element of an air duct.

A heat pipe structure includes a base block including a rear surface part thermally connectable to a heat generating body and a heat pipe fixed to a front surface part of the base block and including a heat receiving tubular portion disposed along an in-plane direction of the base block. The base block has a longitudinal direction and a width direction and includes a recessed part in which the heat receiving tubular portion is housed and a pair of wall parts projecting along an outer circumferential surface of the heat receiving tubular portion from width direction both sides of the recessed part, and a container of the heat pipe is caulked and fixed by the recessed part and the pair of wall parts and includes a projecting shape part projecting in a direction opposite to a direction of the caulking between distal end portions of the pair of wall parts.

An intercooler includes a cooling tube that defines therein a first coolant passage through which a first coolant flows, and a second coolant passage through which a second coolant flows. A pair of plate portions having a predetermined shape are bonded with each other by brazing in a condition where the pair of plate portions are superposed on each other such that the first coolant passage and the second coolant passage are defined between the pair of plate portions. The cooling tube includes a passage partition portion separating the first coolant passage from the second coolant passage at a part of the pair of plate portions between the first coolant passage and the second coolant passage, and at least one through-hole in the passage partition portion. At least one swaged portion that crimps the pair of plate portions is provided in a periphery of the through-hole.
