A cooling system for a wind tunnel is disclosed. The heat exchanger of the present disclosure is formed as a turning vane in an airflow duct of a re-circulating wind tunnels. The individual vanes are formed from extruded aluminum with coolant fluid channels running continually down the length of the vane. One or more channels can be used, depending on the application of vane and the cooling capacity needed. The exterior of the vanes are formed in an airfoil shape to efficiently turn the air flow the desired amount in a manner well known in the art. The turning vanes are connected to a fluid supply with single piece connectors that removably attach to the turning vanes. In the depicted embodiment the connectors are attached with screws. In the depicted embodiment the connectors are formed as a single piece in a two-piece injection mold.

The disclosure relates to a plate heat exchanger in a sealed design, with a stacked arrangement comprising a front-side and a rear-side end plate, wherein at least one end plate is constituted as a connection plate, heat exchanger plates which are arranged and stacked between the front-side and the rear-side end plate, in such a way that cavities for accommodating a plurality of heat exchanger media are formed between the heat exchanger plates, and sealing elements which are disposed to seal the cavities, and a clamping device, configured to exert an external clamping pressure on the stacked arrangement for the tensioning, wherein the clamping device is formed to encompass the stacked arrangement in a form-fit manner at least in sections, namely at least in a corner region of the stacked arrangement.

A heat exchanger fixing structure, for two or more heat exchangers bent in multiple layers, includes two or more plates respectively fixed to one ends of the two or more heat exchangers, wherein portions of the two or more plates may overlap each other, and the two or more heat exchangers are connected and fixed to each other by fastening a fastening member to the overlapping portions.

A liquid cooling apparatus has a chassis, a cover mounted on the chassis, and a dividing structure disposed in an inner chamber defined between the chassis and the cover. The dividing structure divides the inner chamber into a liquid inlet compartment and a liquid outlet compartment. The liquid inlet compartment communicates with the liquid outlet compartment via the recess. The liquid cooling apparatus can be installed on a first panel with the boss of the chassis mounted through a through hole of the first panel and thermally attached to a heat source on a second panel. A working fluid that flows into the liquid inlet compartment is forced to flow into the recess before flowing to the liquid outlet compartment by the dividing structure. Accordingly, heat generated by the heat source can be effectively dissipated.

Vessel assemblies, heat transfer units for prefabricated vessels, and methods for heat transfer prefabricated vessel are provided. A heat transfer unit includes a central rod, and a plurality of peripheral rods surrounding the central rod and connected to the central rod. The plurality of peripheral rods are movable between a first collapsed position and a second bowed position, wherein in the second bowed position a midpoint of each of the plurality of peripheral rods is spaced from the central rod relative to in the first position. The heat transfer unit further includes a heat transfer element connected to one of the plurality of peripheral rods.

A heat exchanger for a motor vehicle may include a tube block and a flange. The tube block may multiple first medium channels and multiple second medium channels. The first and the second medium channels may extend from an inlet of the tube block to an outlet of the tube block. A medium to be cooled may flow through the first medium channels. A cooling medium may flow through the second medium channels. The flange may be configured to receive the tube block about the outlet in a fluid-tight manner. The flange may be plate-like and may have a surrounding bolting region that may be formed about the tube block.

A support and connection device is for an operating group of a vehicle. The support and connection device is configured for supporting and for fluidic connection with an operating device in turn included in the operating group. The support and connection device identifies a vertical axis and two longitudinal axes and includes at least one plate-shaped unit in which, in the vertical direction, there is at least one mouth for the passage of a working fluid. The plate-shaped unit includes an upper laminar element, a lower laminar element reciprocally stacked along the vertical axis and a hollow space between them. The at least one mouth for fluid passage is defined laterally by a fluid mouth wall constituted by the reciprocal engagement of an upper mouth rim included in the upper laminar element and by a lower mouth rim included in the lower laminar element.

Heat exchanger, in particular for cooling power electronics, comprising an insulating element which separates a first fluid medium, which is in contact with a heat source, from a second fluid medium, which differs in at least one property from the first fluid medium and which is in fluid connection with a heat sink or is itself a heat sink, and a heat transfer element which has a higher thermal conductivity than the insulating element, wherein the insulating element comprises at least a first passage opening in which a first heat transfer element is arranged, wherein the heat transfer element is thermally connected both to the first fluid medium and/or the heat source, and to the second fluid medium and is fluidically sealed with respect to the insulating element by means of a sealing element.

A fluid flow channel device includes a main body and a non-ceramic sub-body. The main body has a plurality of internal flow channels, and inlets and outlets thereof are arranged so as to be exposed on an outer side surface. The sub-body has a fluid supply path and a fluid recovery path. A supply port of the fluid supply path is arranged to face the inlets of the plurality of internal flow channels. A recovery port of the fluid recovery path is arranged to face the outlets of the plurality of internal flow channels. By disposing the supply port and the recovery port for transferring the fluid to and from the plurality of internal flow channels in the sub-body, it is possible to prevent a large thermal stress from being applied to the main body.

A port connection includes a first element, a second element, and a seal. The first element has a first sleeve and a first flange. The first sleeve is configured to slide into a port disposed through a pressure plate of the plate heat exchanger and the first flange having a first bearing surface to bear upon a first face of the pressure plate. The second element has a second sleeve and a second flange. The second sleeve is configured to slide into the port and the second flange having a second bearing surface to bear upon a second face of the pressure plate. The seal is generated in response to the first sleeve telescoping into the second sleeve.
