Abstract: In a heat exchanger for a vehicle, a cover member covers an upstream side end that is a part of an outer peripheral surface of a tube in which a heat medium flows, on the upstream side of the air flow. Further, the cover member is fixed to the upstream side end of the tube. For example, a width of the cover member is equal to or less than that of the tube in a direction perpendicular to the air flow direction and a flow direction of the heat medium. Thus, the heat exchanger can prevent the misalignment of the cover member with respect to the tube, thereby protecting the tube by the cover member at the front side of the vehicle. Therefore, the tube can be protected from chipping.

Abstract: A heat exchanger has a core plate connected to a tank member by clamping claws. The tank member has a waved outer surface including outer ridge portions and outer valley portions which are disposed alternately. The tank member also has a waved inner surface including inner ridge portions and inner valley portions which are disposed alternately. The outer valley portions are capable of receiving the claws. The inner ridge portion is positioned inside the outer valley portion in a width direction. The inner ridge portion is positioned between the adjacent tubes and/or between extensions of the tubes in a height direction. An inner width of the tank member regulated by the inner ridge portions is narrower than a width of the tube.

Abstract: A reserve tank includes a vapor-liquid separator, an inlet portion, an outlet portion, and a protrusion. The vapor-liquid separator defines an inner space for separating a vapor phase and a liquid phase of a cooling water. The inlet portion defines a first opening through which the cooling water is supplied into the inner space and the outlet portion defines a second opening through which the cooling water is discharged from the inner space. The protrusion protrudes upward from a bottom surface of the vapor-liquid separator. An inner circumferential surface of the vapor-liquid separator and an outer circumferential surface of the protrusion are coaxially provided to define an annular passage in the inner space. The cooling water introduced from the first opening flows spirally in the annular passage.

Abstract: A stiffener for a heat exchanger includes a top plate and at least two legs extending from opposing sides of the top plate. Each of the at least two legs includes a bent portion, an angled portion, and a straight portion. The bent portion attaches the leg to the top plate. The angled portion increases a width of the stiffener from a width of the top plate. The straight portion extends perpendicular to a plane of the top plate.

Abstract: The heat exchanger has tubes and a header tank that is located at an end of the tubes in a longitudinal direction and communicates with the tubes. The header tank has a core plate that connects to the tubes and a tank body that is fixed to the core plate. The core plate has a tube connection surface, a sealing surface, and an inclined surface that connects the tube connection surface and the sealing surface with each other. A distance between the tube connection surface and an end surface of the tubes in the longitudinal direction is different from a distance between the sealing surface and the end surface in the longitudinal direction by disposing the inclined surface to incline with respect to the longitudinal direction. The tubes connect to the tube connection surface and the inclined surface in a condition of being inserted to the tube connection surface and the inclined surface.

Abstract: A reserve tank includes a gas-liquid separator, a flow inlet portion, a flow outlet portion, and a projection shaped in a tubular form. The gas-liquid separator is shaped in a bottomed tubular form and is centered on a predetermined axis. The flow inlet portion is configured to conduct coolant into an inside of the gas-liquid separator. The flow outlet portion is configured to discharge the coolant from the inside of the gas-liquid separator. The projection extends along the predetermined axis from a bottom wall at the inside of the gas-liquid separator. An inner space of the projection opens to an inner space of the gas-liquid separator at a distal end portion of the projection.

Abstract: A side slit of a core plate of a heat exchanger reaches a sealing surface. The core plate has a rib which is formed on a bottom plate across a protruding portion. The rib communicates to a cavity above the sealing surface. An end slit formed on an end wall of the core plate reaches the sealing surface. A first joining tab is formed between two end slits. The first joining tab is joined to a second joining tab on a reinforce plate. The side slit and the rib enable deformation of the core plate. The end slit enables deformation of the first joining tab in a tilting manner.
