A heat exchanger module unit that provides heat exchange between a fluid and a heat medium by indirect heat exchange through a phase-change material disposed between movement paths of the fluid and the heat medium movement paths, includes: a multiple number of plates having a partition, which is formed with a through-hole through which the fluid and the heat medium move, are stacked with a spacing gap, through which the fluid and the heat medium move, at one side of the partition; the spacing gaps are selectively connected through a connector connecting the respective through-holes so as to form a fluid passage and a heat medium passage through which the fluid and the heat medium move independently respectively; the spacing gap, in which the phase-change material is received, is located and disposed between the spacing gaps forming the fluid passage and the heat medium passage through which the fluid and the heat medium move respectively such that heat exchange is made between the fluid and the heat medium through the phase-change material. One of the fluid and the heat medium is disposed at one side of the phase-change material and another phase-change material is disposed at the opposite side thereof.

A heat exchange spacer is for assembly with a heat exchange core. The heat exchange spacer has a unitary body including a first elongate portion and a second elongate portion. The first elongate portion and the second elongate portion define an angle therebetween.

A heat exchanger, particularly a charge-air cooler, in which heated air is cooled by a cooling fluid, is constructed from stacked pairs of plates with air flow passages arranged between adjacent ones of the plate pairs. Each of the pairs of plates includes an inlet and an outlet for the cooling fluid flow arranged within an inlet and outlet region and aligned with the direction of the air flow through the heat exchanger. A flow barrier formed by beads of the plates is arranged between the inlet and outlet region and a heat exchange section of the plate pair. A flow of cooling fluid is directed through a coolant flow path extending through the plate pair between the cooling fluid inlet and the cooling fluid outlet, with the cooling fluid flow path having a first portion along one longitudinal edge of the plates, a second portion along an opposing longitudinal edge of the plates, and a third portion extending through the heat exchange section between the first and second portions. The flow of cooling fluid through the third portion is in a direction counter to the flow of air.

A heat exchanger comprises a stack of flat tubes defining first and second fluid flow passages, and a housing having side covers over the sides of the core, and being spaced from the sides of the core. The heat exchanger further comprises a bypass seal comprising a pair of side seals and a pair of clip members. The side seals are received between the sides of the core and the housing. Each side seal has an inner surface engaging the first side of the core and an outer surface engaging the first side wall of the housing. Each clip member has a middle portion to which a side seal is connected, as well as opposed first and second end portions which engage inwardly extending surfaces of the core.

A channel forming body for mounting semiconductor power modules or a heat sink for power modules has a heat-transfer portion having a very complicated construction in order to increase the heat-transfer coefficient, leading to need for extremely high techniques and high cost for manufacturing. By arranging an expanded metal 13 in a channel 12 formed to lie between two planes 11 and 11 placed face-to-face, local fluid flows 16 guided by the expanded metal 13 are allowed to act on various boundary layers 15 formed between these two planes 11 and 11 and a fluid so as to improve fluid flow characteristics concerning heat transfer and/or mass transfer through a local turbulent flow acceleration effect.

A high gravimetric and volumetric power density heat exchanger is provided for high-temperature and high-pressure applications with counter-flowing hot and cold agents that enter via respective inlet headers, transit parallel and adjacent flow passages, and exit via respective outlet headers. One or more headers for conveying one of the substances may be situated within the flow of the other substance. Structures within the flow passages promote the transfer of heat while limiting pressure drop on one or both sides. The structures may include microscale pins, an array of pins (with specified aspect ratios and spacing), a lattice of interconnected pins, parallel ridges, and/or other features. Through an additive manufacturing process, the headers are monolithically integrated into the heat exchanger instead of being separately constructed and attached.

A heat exchanger (1) includes a top plate (2) and a bottom plate (3), wherein between the top plate (2) and the bottom plate (3) two heat exchanger stacks (4,7) are provided, wherein the heat exchanger stacks (4,7) are separated by a separating plate (6). The underlying problem of the present disclosure is to provide a heat exchanger (1) which can be adapted easily. This problem is solved by a heat exchanger (1), wherein first heat exchanger plates (5) forming the first heat exchanger stack (4) differ from second heat exchanger plates (8) forming the second heat exchanger stack (7).

A heat exchanger includes: the pair of the oil holes being positioned on an outer edge of one of the core plates, being positioned at symmetrical positions with respect to the center of the one of the core plates to sandwich the center of the one of the core plates, and being positioned to sandwich one of the fin plates along the first reference line, and the pair of the coolant holes being positioned on the outer edge of the one of the core plates, being positioned at symmetrical positions with respect to the center of the one of the core plates to sandwich the center of the one of the core plates, and being positioned to sandwich the one of the fin plates along the first reference line.

A heat exchanger includes: each of the fin plates having a V shaped or trapezoid corrugated shape, and including top walls positioned at top portions of the corrugated shape, bottom walls positioned at bottom portions of the corrugated shape, and foot portions each connecting one of the top walls and one of the bottom walls, each of the foot portions having a rectangular corrugated shape along one of the top walls and one of the bottom walls, and including stepped walls formed at a predetermined interval along the one of the top walls and the one of the bottom walls, and opening portions each formed in one of the stepped walls, and being an elongated through holes having a width equal to or smaller than a thickness of one of the fin plates.

The disclosure relates to a heat exchanger, for example an indirect air cooler, in which the air, for example compressed charge air for an internal combustion engine, is cooled, for example by a fluid, wherein the heat exchanger is constructed from stacked pairs of plates. The exemplary fluid can be conducted into an inlet region and/or outlet region of the plate pairs in at least one flow path approximately in the direction of the common edge, and further through at least a first duct approximately in cross current with respect to the exemplary air, and passes further through the plate pairs over the largest heat exchange area of the plate pairs approximately in countercurrent with respect to the air, in order to flow through at least one second duct, approximately in cross current with respect to the exemplary air, and back to the outlet.
