A heat exchanger for a motor vehicle includes a seal and a core. The core includes a first groove formed in a first side and a second groove formed in an opposing second side. The first groove and the second groove are each configured to receive a portion of the seal to secure the seal to the core. The seal includes a cross member and a pair of uprights extending from opposing ends of the cross member, wherein the cross member and the uprights each include a sealing element. The uprights further include a rail extending from the upright and configured to be received in the groove of the core. The core further includes an integrated shear panel formed at opposing ends thereof.

Plate (110) for a heat exchanger (100) between a first medium and a second medium, the plate comprising a first heat transfer surface (114) on a first side (113) of the plate, arranged to be in contact with the first medium; a second heat transfer surface (116) on a second side (115) of the plate, arranged to be in contact with the second medium; a plurality of indentations (120, 130, 140) in the plate (110; 210; 310), bulging out locally in a plate height direction (H), which plate is arranged to be stacked together with similar plates to form a heat exchanger heat plate stack. The invention is characterised in that the plate comprises a ridge-shaped indentation, arranged to form, together with a corresponding ridge-shaped indentation of an adjacent plate in said stack, a closed flow channel (105′, 105″) for the first medium with a general flow direction, in that the said closed channel comprises a floor (105a) and a ceiling (105b), as viewed in the height direction, and comprises a step (105c) in the height direction along said general flow direction by the said floor and said ceiling both being offset in same height direction.

A structure of a drawn cup-type heat exchanger of improved pressure tightness is provided. A drawn cup-type heat exchanger is configured by stacking in plural number a long and thin tube element containing an inner fin inside a pair of cup plates. The cup plates have a flat containing portion containing the inner fin and a pair of cup portions communicating with both end portions of the containing portion; a circulation hole for communicating fluid into each of tube elements to be stacked is formed in the cup portions; and, to position both end portions in a longitudinal direction of the inner fin to be contained in front of the circulation hole of the cup portions, a corner portion is formed at at least one end portion in a width direction at both extremities in a longitudinal direction of the containing portion.

A liquid panel assembly configured to be used with an energy exchanger may include a support frame having one or more fluid circuits and at least one membrane secured to the support frame. Each of the fluid circuits may include an inlet channel connected to an outlet channel through one or more flow passages. A liquid is configured to flow through the fluid circuits and contact interior surfaces of the membrane(s). The fluid circuits are configured to at least partially offset liquid hydrostatic pressure with friction loss of the liquid flowing within the fluid circuits to minimize, eliminate, or otherwise reduce pressure within the liquid panel assembly.

This air distributor (1) has an exterior casing defining an interior volume, an air inlet (4) opening into this interior volume, several air outlets (4) intended to convey air from the interior volume towards the cylinders of an engine, and a heat exchanger (8) arranged in the interior volume. The heat exchanger (8) comprises a stack of plates (10) of plastic material where adjacent plates (10) are arranged so as to define a set of intermediate spaces comprising closed intermediate spaces (12) in fluid communication to enable circulation of fluid through the stack of plates (10), and open intermediate spaces (14) configured to enable a passage of air through the stack of plates (10) from the air inlet (4) to the air outlets (6).

The invention relates to a brazed heat exchanger incorporating an aluminium alloy baseplate and wherein the baseplate is made from an aluminium alloy having a composition, in wt. %, of: Mn 0.8-1.8, Cu 0.15-1.20, Si 0.25-1.30, Mg 0.10-0.60, Fe≤0.8, Zn≤0.3, Ti≤0.20, Cr≤0.25, Zr≤0.25, balance aluminium and impurities.

A plate stack includes a plurality of plates, each including corrugated portions formed on front and back surfaces thereof. First and second heat exchange flow passages are formed between plates, arranged alternately along stacking direction of the plates. Each plate has two through holes penetrating the front and back surfaces, through which the first heat exchange fluid is introduced and derived. The plate stack includes first partition weirs formed on at least one of two plate surfaces, the two plate surfaces forming a corresponding one of the first heat exchange flow passages therebetween. First partition weirs are symmetrically and obliquely arranged with respect to a center line connecting centers of two through holes as viewed from the stacking direction. A flow passage is formed along the center line on a side of at least one of the two through holes, from which first heat exchange fluid is introduced.
