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 lubricant filter housing comprises a top plate defining a first opening. A base plate is positioned opposite the top plate. The lubricant filter housing further comprises at least one sidewall which cooperatively with the top plate and the base plate defines an internal volume. A plurality of plates are axially positioned in the internal volume between the top plate and the base plate. Each plate defines a plate opening axially aligned with the first opening which cooperatively with the first opening and a portion of the base plate, defines an internal cavity for housing a filter element. The plates define a first set of fluid channels structured to deliver a lubricant to the internal cavity, and a second set of fluid channels structured to provide a coolant around the first set of fluid channels.

The invention relates to a plate (105) forming part of a heat exchanger and intended to delimit at least one channel (111a, 111b) for circulation of a fluid. The plate (105) comprises a bottom (106), and at least one raised edge (107) which surrounds the bottom (106). The plate (105) comprises at least one opening (110) configured to supply the channel (111a, 111b) with fluid. The opening (110) is shaped according to an opening profile (X1). The plate (105) is equipped with a fluid distribution means (300) shaped according to a distribution means profile (X2) which is homothetic with the opening profile (X1) of the opening (110).

The present invention relates to a heat exchanger. The purpose of the present invention is to provide a heat exchanger formed to enable two different types of fluids and one other type of fluid to undergo heat exchange with each other, that is, formed to resultingly enable three types of fluids to undergo heat exchange with each other. More specifically, provided is a heat exchanger formed so that two types of coolants having different temperature ranges, such as a coolant for cooling a battery and a coolant for cooling a motor, and one type of refrigerant in an electric vehicle may undergo heat exchange by means of one heat exchanger.

An air fin for a heat exchanger has air channels defined by corrugations, the corrugations having generally planar flanks joined by alternating crests and troughs. Perforations extend through portions of at least some of the flanks and are aligned within two spaced apart planes. A rectangular aperture extends through at least two consecutive ones of the corrugations, and is bounded by the two planes. A method of making the air fin includes forming perforations into a continuous strip of metal sheet at regular intervals, corrugating the strip to form crests and troughs between the perforations, and punching out a portion of the strip at regular intervals. The punching out includes shearing webs between the perforations, and results in the formation of the rectangular aperture.

A stacked plate heat exchanger for a motor vehicle may include a plurality of elongated plates stacked on one another between which a plurality of cavities are disposed alternately for two media. The plurality of cavities may be respectively delimited by a respective plate of the plurality of plates zonally by a plate surface and a surrounding wall. The respective plate may include two flow openings, two passage openings, and two domes respectively arranged around one of the two passage openings. At least of one of the plurality of plates may further include an elongated separation shaping arranged on the plate surface, projecting into the respective cavity, and extending from the first short side between the two flow openings in a direction of the second short side. The separation shaping may adjoin the first short side at an angle α of 45° to 90°.

Heat-energy exchange device having a first and a second plat heat exchanger, each plate heat exchanger being configured to allow exchanges of heat energy between at least two heat-transfer fluids at different temperatures. The exchange device further includes a distribution member sandwiched between the first and second plate heat exchangers, said distribution member including a series of channels made within it, said channels connecting inlets and outlets of heat-transfer fluid of the first and second plate heat exchangers to connection orifices positioned on said distribution member.

A heat exchanger is provided with a unitary, single-piece structure that can be formed via 3D printing, for example. The heat exchanger includes a main body a plurality of plates stacked and integrally formed with the body. First fluid channels are defined by gaps in the material of the main body, and second fluid channels are defined by gaps in the material of the main body and are stacked with the first fluid channels in alternating fashion, separated by the plates. Each of the first fluid channels define a first flow path, and each of the second fluid channels define a second flow path. A portion of the first flow paths overlap, and are oriented opposite to, a portion of the second flow paths. Another portion of the first flow paths overlap, and are oriented transverse to, another portion of the second flow paths.

A plate-stacked heat exchanger is proposed which exchanges heat with high heat exchange efficiency in flow paths each including an internal space bulging outward between two heat transfer plates. A flow path forming portion includes a plurality of flow path bulging portions that bulges outward of a heat exchanger plate and forms heat exchange flow paths of a first heating medium therein, and a header portion includes a communication hole communicating with the header portion of an adjacent heat exchanger plate, and a flow path forming portion-side expanded portion expanding from the communication hole toward the flow path forming portion, and the flow path forming portion-side expanded portion communicates with the plurality of heat exchange flow paths. Consequently, heat can be exchanged in a greater width. Therefore, a high heat exchange rate can be obtained.

A pin for a core layer of a heat exchanger, the pin extending from a first pin end to a second pin end and having an outer surface between the first and second pin ends, wherein the pin comprises a plurality of surface features protruding from the outer surface.
