Systems are provided for a heat exchanger assembly. In one example the system may include a top plate, a fluid inlet and a fluid outlet, a bottom plate coupled to the top plate, a perforated plate positioned between the top plate and the bottom plate having an underside facing the bottom plate and including perforations shaped to generate an impingement jet onto the bottom plate, and at least one of the following: the top plate comprising a portion being inclined with respect to a longitudinal axis of the heat exchanger assembly; the perforated plate being inclined with respect to the longitudinal axis or a lateral axis of the heat exchanger assembly; and the heat exchanger assembly further comprising a flow control plate.

Systems for a heat exchanger

A modular heat exchanger for battery thermal management having a plurality of similarly constructed heat exchange elements affixed to a cover plate and fluidly coupled with one another via a single external manifold structure that functions as both an inlet manifold and an outlet manifold for each of the heat exchange elements. Rigidity is improved with alternating tabs or overlapping tabs between adjacent elements, and/or side edges between adjacent elements having cutouts for receiving stiffening ribs formed in the cover plate. The external manifold structure provides additional stiffening for the interconnected heat exchange elements.

Modular heat exchangers for battery thermal modulation

A heat exchanger includes first and second plates joined together with portions of the inner surfaces spaced apart to define a plurality of fluid flow passages for flow of a heat transfer fluid. A dividing rib separates the heat exchanger into an inlet section and an outlet section, each of which includes a plurality of fluid flow passages. Inlet and outlet ports are located near a first end of the heat exchanger, on opposite sides of the dividing rib. The heat transfer surface area of the inlet section is less than that of the outlet section due to the presence of one or more flow obstructions between the inlet port and first ends of the fluid flow passages in the inlet section. Each flow obstruction may be a dead channel including a continuous outer rib completely surrounding a depressed middle region.

Utilization of dead channel to improve temperature uniformity on thermal interface material

A heat exchanger has a fluid flow passage having an inlet and an outlet, and with a first plate and a second plate in opposed facing relation to one another. The fluid flow passage is defined by a space between the inner surfaces of the first and second plates. An electrical heating element is outside the fluid flow passage and adjacent to the outer surface of the first plate, such that heat produced by the electrical heating element is transferred through the first plate to the fluid in the fluid flow passage during use of the heat exchanger. In an embodiment, the first plate has an opening to receive a heater plate component including a first plate portion having an inner surface bonded to a turbulence-enhancing insert and an outer surface bonded to the electrical heating element.

Heat exchanger with integrated electrical heating element

A heat exchanger having an integrated support structure particularly suited for thermal management of heat generating components such as battery thermal management applications or thermal management of other electronic components is disclosed. The heat exchanger includes a top plate and a base tray defining a plurality of fluid channels that extend between an inlet manifold area and an outlet manifold area. The top plate has a first side defining a primary heat transfer area and a second side for effecting a sealing relationship between the top plate and the base tray. In some instances, the top plate includes a thermally conductive material while the base tray includes a non-thermally conductive material. In some instances the base tray cooperates with a cover portion to define an enclosure for housing the heat generating components.

Heat exchanger with integrated support structure

A heat exchanger for thermal management of battery units made-up of a plurality of battery cells or battery cell containers housing one or more battery cells. The heat exchanger has a main body portion defining at least one primary heat transfer surface for surface-to-surface contact with a corresponding surface of at least one of the battery cells or containers. A plurality of alternating first and second fluid flow passages are formed within the main body portion each defining a flow direction, the flow direction through the first fluid flow passages being generally opposite to the flow direction through the second fluid flow passages. In some embodiments the heat exchanger has two pairs of inlet and outlet manifolds, providing a single-pass, counter-flow arrangement. In other embodiments the first and second fluid flow passages are interconnected by turn portions forming a U-flow, counter-flow heat exchanger.

Counter-flow heat exchanger for battery thermal management applications

Methods and systems are provided for heat exchangers including a first outer plate, a second outer plate, and an intermediate plate. The intermediate plate is positioned between the outer plates. Fluid flow passages are formed between the intermediate plate and each of the outer plates.

A heat transfer surface for use in conjunction with a heat exchanger is disclosed. The heat transfer surface a corrugated member where rows of corrugations that are offset relative to each other forming at least an alternating series of first and second rows or first, second and third rows. In some embodiments the heat transfer surface includes a heat transfer enhancement feature disposed within individual corrugations of the corrugated member to provide a more turbulent or tortuous fluid flow path through the heat transfer surface. In some example embodiments the heat transfer enhancement feature is a ridge disposed in the planar portions of at least some of the rows of corrugations. In other example embodiments the planar fin portions are porous fin surfaces. In other embodiments, the corrugated member cooperates with heat transfer enhancement features in the form of triangular protuberances disposed on their inner surfaces of spaced apart plates.

Enhanced heat transfer surface

A cold plate heat exchanger for battery thermal management has first and second plates defining a plurality of fluid flow passages, with inlet and outlet ports proximate to a first end thereof. Each fluid flow passage has first and second ends communicating with respective inlet and outlet ports. One or more portions of each fluid flow passage are immediately adjacent to and in close proximity to a portion of another fluid flow passage or channel, such that heat energy will be transferred by conduction through the first and second plates between the fluid flow passages or channels, thereby providing enhanced heat transfer. The fluid flow passages or channels may be separated by a distance which is less than a width of one of the fluid flow passages or channels, and may be separated by a single rib which partially defines each of the fluid flow passages or channels.
