A temperature control device for a gaseous media. The temperature control device includes a first heat exchanger layer in which a medium channel for a gas to be temperature-controlled is formed, a second heat exchanger layer which extracts heat from and/or supplies heat to the first heat exchanger layer, and a diffusion layer which is arranged between the first heat exchanger layer and the second heat exchanger layer. The diffusion layer is open to the gas to be temperature-controlled.

A heat exchanger having a heat exchanger core which is configured as a plate stack has a flange plate including at least one upper partial plate facing the heat exchanger core and at least one lower partial plate facing away from the heat exchanger core. The flange plate can include a supercooling passage which is bounded by at least one partial plate in the stacking direction of the partial plates and which receives a flow of refrigerant during the operation of the heat exchanger. A high variability can be provided thanks to the compact and flexible design, by means of which the most diverse of requirements can be achieved with no major design changes.

Examples of a cooling system include a flow channel through which a cooling medium flows, a valve that is provided in the flow channel and configured to adjusts a flow rate of the cooling medium, a thermometer for measuring temperature of the cooling medium, a flowmeter for measuring a flow rate of the cooling medium passing through the valve, and a controller for determining cooling capacity of the cooling medium from measurement results of the thermometer and the flowmeter, and adjusting the valve so that the cooling capacity of the cooling medium approaches to a target value when the determined cooling capacity is different from the target value.

A heat exchanger for a vehicle includes: a housing having an interior space; a header installed at one end of the housing and having a first fluid inlet manifold; a second fluid inlet manifold; and a second fluid outlet manifold; and a heat exchange core installed in the interior of the housing and having a plurality of core elements spaced apart from each other. The plurality of core elements are coupled to the header, and a plurality of first fluid passage, through which the first fluid passes, is respectively formed between the adjacent core elements. Each of the core elements has a second fluid passage, through which the second fluid flows, an inlet of the second fluid passage communicates with the second fluid inlet manifold, and an outlet of the second fluid passage communicates with the second fluid outlet manifold.

Heat exchanger assemblies and methods are provided for cooling the interior of an enclosure (e.g., electrical cabinets, computer server racks, chemical chambers, and animal cages). Heat is transferred via thermal conduction from a first plurality of surfaces positioned inside the enclosure to a second plurality of surfaces positioned outside the enclosure. The first and second plurality of surfaces remain in thermal contact with one another during use. Heat is dissipated from the second plurality of surfaces to the ambient air outside the isolated environment without the ambient outside air mixing together with the air inside the enclosure. This, in turn, inexpensively removes heat from the air inside the enclosure and prevents contaminants from entering the enclosure.

An additively manufactured heat exchanger can include a plurality of vertically built fins, and a plurality of non-horizontally built parting sheets. The plurality of vertically built fins can extend between and connect to the plurality of parting sheets. The heat exchanger can include a plurality of layers of fins and parting sheets. The heat exchanger can include first and second flow circuits for allowing separate fluid flows to flow through the heat exchanger to exchange heat therebetween.

An assembly for transferring heat with respect to one or more components, such as for cooling power electronics, computer processors and other devices. Components may contact heat transfer surfaces which are heated or cooled by a heat transfer fluid. The heat transfer surfaces may be supported by a connecting portion which may allow the heat transfer surfaces to be movable relative to each other.

Examples of a cooling system include a flow channel through which a cooling medium flows, a valve that is provided in the flow channel and configured to adjusts a flow rate of the cooling medium, a thermometer for measuring temperature of the cooling medium, a flowmeter for measuring a flow rate of the cooling medium passing through the valve, and a controller for determining cooling capacity of the cooling medium from measurement results of the thermometer and the flowmeter, and adjusting the valve so that the cooling capacity of the cooling medium approaches to a target value when the determined cooling capacity is different from the target value.

Exchanger (1) of heat between a first fluid flowing in a longitudinal direction (X) and a second fluid, the said exchanger (1) comprising: two parallel plates (6) distant from one another; at least a first and second row (8a, 8b) of fins (9) arranged perpendicularly between the said plates (6), each fin (9) being delimited longitudinally by a first edge (10) and a second edge (11), the said first edge (10) comprising at each of its ends a region of connection with the corresponding plate (6);

characterised in that the said connection regions of the said first edge (10) are respectively inclined with respect to a normal to the plates (6) in a plane (P) perpendicular to the said plates (6) and parallel with the direction (X), the said first edge (10) and the said second edge (11) of each of the fins (9) having identical profiles in the said plane (P).

A method for producing heat exchangers having at least two fluid circuits each having channels, including the following steps: producing one or a plurality of elements of a first fluid circuit, each element having at least two metal plates, at least one of which has first grooves; stacking the at least two metal plates of each element in such a way that the first grooves form the channels of the first circuit; assembling each element of the first circuit by diffusion welding between the two stacked metal plates; producing one or a plurality of elements of at least one second fluid circuit, each element of the second circuit having at least a portion of the channels of the second circuit; assembling, either by diffusion welding, or by brazing, or by diffusion brazing between the element or elements of the first circuit and the element or elements of the second circuit.
