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.

A cooling apparatus for a hydrostatic transmission includes a cooling body to be coupled with a hydrostatic transmission, a sidewall member protruding from the cooling body to surround a cooling flow path which cools a working fluid supplied from the hydrostatic transmission and discharges the working fluid into the hydrostatic transmission or a storage tank, an installing member protruding from the cooling body at a position spaced apart from the sidewall member to be disposed inside the sidewall member, a detour member connected to the installing member and protruding from the cooling body to extend in a first axial direction to allow the working fluid, which flows along the cooling flow path, to make a detour, and a plurality of protruding members protruding from the cooling body to be spaced apart from each of the sidewall member, the installing member, and the detour member in the cooling flow path.

A transfer tube for a thermal transfer device can include at least one wall having an inner surface and an outer surface, where the inner surface forms a cavity, where the at least one wall further has a first end and a second end. The first end can be configured to couple to a terminus of a heat exchanger of the thermal transfer device. The second end can be configured to couple to a collector box of the thermal transfer device. At least a portion of the at least one wall can be disposed in a vestibule of the thermal transfer device. The cavity can be configured to simultaneously receive a first fluid that flows from the first end to the second end and a second fluid that flows from the second end to the first end.

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.

Various embodiments of the present disclosure provide a heat sink for a plug-in storage card and a plug-in storage card including the heat sink. The heat sink comprises a first part secured to a surface of the plug-in storage card and a second part coupled to the first part and being movable relative to the first part in a first direction, wherein the first direction is perpendicular to the surface of the plug-in storage card. In this way, when the second part and the first part have a larger overlap in the first direction, the heat sink has a smaller first height and when the second part and the first part have a smaller overlap in the first direction, the heat sink has a greater second height.

A heat exchanger assembly includes a frame; first and second heat exchanger panels configured for exchanging heat with air pulled into the heat exchanger assembly and disposed in a V-configuration; a fan for pulling air into an enclosed space of the heat exchanger assembly; a plurality of lateral enclosing panels and at least one middle enclosing panel. The at least one middle enclosing panel extends perpendicular to the lateral enclosing panels and is disposed between the heat exchanger panels. A U-shaped lower end of the at least one middle enclosing panel includes first and second wall portions opposite one another. The lower ends of the heat exchanger panels abut the wall portions such that the wall portions are deflected relative to one another by forces exerted thereon by the lower ends causing a first and second seals to form between the wall portions and the heat exchanger panels.

A heat exchanger assembly has a frame including: a plurality of legs; first and second lower transversal members extending perpendicular to and interconnecting the legs; a plurality of upstanding members extending upwardly from respective ones of the legs, a lower end of each upstanding member being connected to a corresponding leg at a junction therebetween; an upper transversal member interconnecting upper ends of the upstanding members; and an upper frame assembly. The frame components are weldlessly connected to one another. First and second heat exchanger panels exchange heat with air pulled into the heat exchanger assembly and are disposed in a V-configuration. An upper end of each heat exchanger panel is connected to upper retaining members of the upper frame assembly. A fan pulls air into the enclosed space of the heat exchanger assembly via at least one of the heat exchanger panels.
