  • Patent number: 10355331
    Abstract: A heat exchanger panel has a heat transfer surface with first and second heat transfer zones of different cooling capacities. Each zone has a subgroup of fluid flow passages having a flow capacity, each extending between a fluid inlet passage and a fluid outlet passage. Where one of the zones is adapted for cooling the tabs of a battery cell, the heat exchanger panel comprises at least one first header located at an end of the panel, including a fluid inlet header and/or a fluid outlet header, a second header at the opposite end of the panel, and a plurality of flow passages extending between the headers. At least one header has a height which is greater than the height of the flow passages, and is substantially the same as a spacing between tabs of adjacent batteries when separated by one of said heat exchanger panels.

  • Patent number: 10295282
    Abstract: A heat exchanger has at least one plate pair comprising first and second plates with a fluid flow passage defined between the first plate and second plates. The inlet opening and the outlet opening in each plate pair are proximate to a first end and an elongate flow barrier separates the fluid flow passage into inlet and outlet portions, wherein a gap through and the flow barrier is provided proximate to the second end of each plate pair. A flow obstruction is located in the gap of each plate pair, the flow obstruction having first and second arcuate sides and being spaced from the terminal end of the flow barrier. The flow obstruction is substantially crescent-shaped, such that a middle portion of the flow obstruction is wider than the opposed ends.

  • Patent number: 10274259
    Abstract: A heat exchanger for a battery has fluid-carrying panels and defines a multi-sided enclosure for enclosing at least two sides of the battery. The heat exchanger has first and second fluid-carrying panels defining first and second flow channels, where the first and second fluid-carrying panels are arranged at an angle to another. The heat exchanger may also include a third fluid-carrying panel defining a third flow channel, and being arranged at an angle to the second fluid-carrying panel. The heat exchanger has first and second plates sealingly joined together along their peripheries and defining a fluid flow passageway between their central fluid flow areas. The second plate may be compliant, its central fluid flow area being deformable away from the central fluid flow area of the first plate in response to a pressure of a fluid inside the fluid flow passageway.

  • Patent number: 9121316
    Abstract: A device for recovering heat from a hot gas stream comprises a gas diverter valve and a gas/liquid heat exchanger. The diverter valve comprises a valve body; a valve element movable between a bypass position and a heat exchange position; and a gas inlet and a gas outlet formed in the valve body. The heat exchanger comprises a heat exchanger core comprised of a stack of core plates arranged parallel to the exhaust gas flow path, and the heat exchanger is located outside the exhaust gas flow path and may be spaced therefrom so as to avoid unwanted heat transfer with the valve in bypass mode. The heat exchanger may include a bottom-most gas flow path adjacent to the bottom plate, and may include a mounting plate which is mechanically secured to the valve body, with a thermally insulating gasket provided between the mounting plate and the valve body.

  • Patent number: 6976531
    Abstract: A heat exchanger in which a heat exchanger core is disposed within a casing which includes a side wall formed by bending a plate into the form of a sleeve in which edges of the plate are in adjacent, confronting relationship with an inwardly projecting, transversely extending deformation, the deformation being disposed between a pair of press members with one of the press members being transversely inserted within the sleeve. The press members are moved together to remove the deformation with resultant pivoting of the edges into abutting contact or overlapping relationship. The heat exchanger core is formed of a plurality of stacked plate pairs each having a plate in inverted orientation. Outwardly projecting ribs of anticlastic form are so formed in each plate that the ribs on each plate of each plate pair are interengagingly intersect with the ribs on the adjacent plate of the adjacent plate pair accurately to align the plate pairs in the heat exchanger core.
