A cold layer adapted for use in a cross counter flow heat exchanger core includes a hot inlet tent for receiving hot flow and a hot outlet tent for discharging hot flow. The cold layer is configured to receive a cold inlet flow and discharge a cold outlet flow defining a main cold flow direction. The cold layer includes a first and second cold main closure bar, each parallel to the main cold flow direction and located near the respective hot inlet or outlet tent, cold main fins perpendicular to the direction of the hot inlet flow, and cold inlet corner fins near the hot inlet tent, configured to receive a portion of the cold inlet flow in a direction that forms an angle with the main cold flow that is greater than 5 degrees.

A heat exchanger may include a stacked plurality of plates and a fin plate brazed to each other. Each set of adj acent said plates of the plurality of the plates may define a flow path between plates. Each plurality of the plates may include a flow-through portion penetrating through the plates and through which a fluid is flowable. At least one set of the flow-through portions may be provided at one of the flow paths such that the fluid is flowable from one side of a flow-through portion to an other side of a flow-through portion. The flow-through portion may be disposed outside the fin plate. Each plurality of the plates may further include a through hole disposed outside the fin plate. Each plurality of the plates may further include a first boss portion formed in a substantially elliptical shape surrounding the flow-through portion and the through hole.

A heat exchanger can be configured to utilize multiple sections of hardway fins that can be configured so that an upper first section of the fins can build up liquid head and a second lower section of the fins can be configured to distribute liquid in an even, or uniform, manner. The first section of fins can utilize a different type of hole arrangement than the second section of fins. For instance, the diameter or width of the holes in the first section may differ from the diameter or width of the holes of the second section. In addition (or as an alternative), fin frequency and/or spacing between immediately adjacent holes in the first section of fins may be different from the spacing between immediately adjacent holes in the second section of fins.

Planar element adapted to form, when stacked with a plurality of other such elements, a heat exchanger, comprising an inlet region, a first zone adapted to direct flow from the inlet region towards a second zone, a second zone comprising at least one cutout in the plane of the planar element, adapted to accommodate a cooling core, a third zone, adapted to direct flow from the second zone towards an outlet region and an outlet region, the planar element comprising a first blockage protrusion disposed along a first group of said side edges, the first group comprising at least a side edge adjacent to said outlet region, and a second blockage protrusion disposed along a second group of said side edges, the second group comprising at least a side edge adjacent to said inlet region.

A compact heat exchanger is provided, in which multiple streams can flow within the same layer or layers, and different fluids may flow in alternating channels within the same layer as well as flowing in alternating layers. Having fluids in alternating channels—as compared to only alternating layers within the same layer—increases the direct surface area between the fluids (the primary surface area) for heat transfer, thereby increasing the rate and efficiency of heat transfer. Methods of making and using the heat exchanger are also provided.

A baffle support and a baffle for a block-type heat exchanger. The baffle support comprises a base plate extending in a first direction and a transverse second direction. The baffle support comprises a first pair and a second pair of projections extending from the front surface of the base plate to engage the baffle. The first pair of projections is located further in the first direction than the second pair of projections. The baffle comprises a mounting member at each transverse edge of a baffle plate. Each mounting member comprises at least one stop surface) facing a first longitudinal edge of the baffle plate. A baffle assembly comprising two baffle supports and a baffle.

A heat exchanger such as a cold plate or ICE plate has an integrated electric heating element provided on an external heater support surface of the heat exchanger. The external heater support surface is directly opposite to an internal surface of the heat exchanger which at least partly defines one or both of the inlet manifold and the outlet manifold. A thermal management system for a vehicle having a plurality of rechargeable battery units includes a circulation loop for circulating a first volume of the heat transfer fluid, and a plurality of battery heat exchangers, including a first heat exchanger with an integrated electric heating element. A sub-loop of the circulation loop includes the internal fluid flow passage of the first heat exchanger, and is adapted for a second, smaller volume of the heat transfer fluid.

Disclosed is a heat exchanger, including a plurality of adjacent sheets. An upper surface of each sheet is provided with a plurality of raised peak lines that are arranged in parallel and spaced rows and raised upward, and a lower surface of each sheet is provided with a plurality of raised contour lines that are arranged in parallel and spaced rows and raised downward. A first flow channel and a second flow channel are formed between adjacent three sheets. Fluid flows through the first flow channel along a first direction and a second direction, and fluid flows through the second flow channel along the first direction and a third direction. A convection is formed by the fluid flowing through the first flow channel and the second flow channel. The present disclosure can improve heat exchange efficiency and be easy to industrialize.

A heat exchange core according to one embodiment includes: a header flow path that extends in a first direction; and a plurality of branching flow paths that are connected to the header flow path and extend in a second direction intersecting with the first direction. A first angle formed by the header flow path with respect to a virtual connection plane between the header flow path and the plurality of branching flow paths is less than a second angle formed by the branching flow paths with respect to the connection plane.
