The flow speed distribution of a refrigerant in a cooling apparatus is made uniform. A cooling apparatus provided includes: a top plate; a casing portion having a base plate facing the top plate, and a refrigerant delivery portion arranged between the top plate and the base plate, the casing portion provided with two opening portions to function as an inlet port through which a refrigerant is let into the refrigerant delivery portion and an outlet port through which the refrigerant is let out; a cooling fin portion arranged in the refrigerant delivery portion of the casing portion and between the two opening portions; and a loss adding portion arranged in the refrigerant delivery portion of the casing portion and between the cooling fin portion and at least one of the two opening portions, the loss adding portion generating pressure loss in the refrigerant passing therethrough.

A tube for a heat exchanger includes a tube outer body enclosing a tube inner volume, and a corrugated insert received within the tube inner volume. The tube outer body has a pair of broad planar walls joined by arcuate end walls. The corrugated insert defines flow channels through the tube, with opening in flanks of the insert allowing for flow communication between adjacent flow channels. Bypass channels adjacent the arcuate end walls are fluidly isolated from the adjacent flow channels by the absence of such openings in the end flanks. Flow through the bypass channels is obstructed by flow blocks at one or both ends of the bypass channels.

A plate heat exchanger includes a plurality of first heat transfer plates, a plurality of first inner fins, a plurality of second heat transfer plates, and a plurality of second inner fins. A space is formed between each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates. The plate heat exchanger includes, in the space, a plurality of heat transfer components connecting each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates, the plurality of heat transfer components being interspersed between each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates. A recess-and-projection pitch section in each of the plurality of first inner fins includes first pitch sections and one or more of second pitch sections, a width of each of the second pitch sections being wider than a width of each of the first pitch sections. The plurality of heat transfer components are disposed in regions of the first pitch sections when the plurality of heat transfer components are projected in a direction in which the plurality of first heat transfer plates and the plurality of second heat transfer plates are stacked.

A heat exchanger is provided and includes parting sheets flat along a first axis and curved along a second axis perpendicular to the first axis, a fin sheet interposed between the parting sheets and corrugated along the first axis to form fins that are curved along the second axis and diffusion bonds formed along an entire length of a fin to diffusion bond the entire length of the fin to the parting sheets.

A battery module or battery pack is provided having a serpentine counter flow cold plate with improved dissipation of heat from individual battery cells, wherein the cold plate provides a more uniform temperature gradient across the cold plate to more evenly transfer heat from the battery cells to liquid coolant circulating through the cold plate. The cold plate selectively omits turbulator material upstream of turbulators to control and govern the coolant fed into and through the turbulators to provide a more uniform temperature gradient across the cooling surfaces.

A heat sink structure with heat pipe includes at least one aluminum fin assembly and at least one copper heat pipe, which are made of dissimilar metal materials. The aluminum fin assembly includes at least one through hole and al least one groove, in which a copper embedding layer is provided for contacting with and connected to the copper heat pipe. By providing the copper embedding layer, the connection between the aluminum fin assembly and the copper heat pipe made of dissimilar metal materials is improved, and the problems of eutectic grains formed on the surface of the aluminum fin assembly and environmental pollution caused by electroless nickel plating are eliminated.

A heat exchanger includes a plurality of plate fins. At least one plate fin has a plurality of holes arranged in one or more rows and a contoured region formed adjacent one of the plurality of holes having a sinusoidal corrugation. The contoured region includes a plurality of elongate adjustable lance elements. The plurality of elongate adjustable lance elements are lowered relative to a central plane arranged at a midpoint of an amplitude of the sinusoidal corrugation.

A cooler, having individual cooling elements (1) of stacked construction having ducts (25) extending in parallel to one another, each of which delimits a flow chamber (29) for the throughflow of a liquid medium to be cooled, between which at least two layers (3, 5) of individual rows of meandering fins (34) extend, which for the throughflow of air jointly delimit a further flow chamber (26, 28) each, is characterized in that the respective one flow chamber (29), free of obstacles, permits a laminar flow of the liquid medium through the assignable duct (25) in one throughflow direction, in that the height (H1) of each fin (34), viewed transversely to the direction of throughflow of the liquid medium, has at least the same height as the free throughflow cross section of the flow chamber (29) of the adjacently arranged duct (25), viewed in parallel to the extension of the respective fin (34), and in that in every layer (3, 5), a plurality of rows (36) of several fins (34) are arranged in succession, which each viewed in the direction of throughflow of the duct (25) are offset from each other.

A heat exchanger includes a fin arranged in a first passage and a tubular tank portion formed so as to penetrate plate members stacked in a stacking direction. An inflow port is formed in a peripheral wall of the tank portion to allow a refrigerant to flow into the first passage. When the fin is arranged in a fin installation portion in the first passage, a passage reduction portion is formed at the inflow port and is narrower than a width of the fin installation portion in the stacking direction.

A battery module or battery pack is provided having a serpentine counter flow cold plate with improved dissipation of heat from individual battery cells, wherein the cold plate provides a more uniform temperature gradient across the cold plate to more evenly transfer heat from the battery cells to liquid coolant circulating through the cold plate. The cold plate selectively omits turbulator material upstream of turbulators to control and govern the coolant fed into and through the turbulators to provide a more uniform temperature gradient across the cooling surfaces.
