A diode lighting module comprising both a diode matrix mounted on a support plate and heat dissipator means for dissipating the heat given off by the diode matrix, includes a metal plate having an outside face in contact with the support plate and an inside face supporting a cellular metal foam including a plurality of calibrated holes passing through each cell in two perpendicular directions, and a vessel-forming box filled with the cellular metal foam and for which the metal plate constitutes a lid. The box has inlet and outlet orifices passing through the box to receive a cooling liquid, and a separator defining two separate cooling fluid flow zones in the cellular metal foam, a cooling fluid feed zone and a cooling fluid discharge zone, with passage from one of the zones to the other taking place through a cutout in the separator.

A heat exchanger for battery cooling is provided to improve an efficiency of cooling of the current heat exchangers. The heat exchanger for battery cooling comprises an upper housing with a fluid inlet and a fluid outlet, a lower housing capable of hermetically connecting with the upper housing to form a chamber for accommodating fluid. The fluid flows into the chamber through the fluid inlet and then exits through the fluid outlet. The fluid chamber is provided with at least one S-shaped fluid directing element with several through holes. With the S-shape directing elements within the fluid chamber and the through holes formed on the directing elements, fluid can flow in an injecting manner within the chamber to realize effective cooling of the upper housing.

A liquid cooling jacket is produced by forming a first butted portion where a step side face of a peripheral wall portion and an outer peripheral side face of a sealing body butt each other and a third butted portion where a step side face of a support pillar portion and a hole wall of the hole portion of the sealing body portion butt each other with a gap, and friction-stirring by inserting a tip side pin and a base side pin of a primary joining rotary tool that is rotating into the sealing body and moving the primary joining rotary tool along the third butted portion with an outer circumferential face of the tip side pin being kept off the step side face while having a second aluminum alloy of the sealing body flow into the gap.

A thermal management system for an electric component has a housing for the electric component and a heat exchange plate extending over the surface of the lateral face of the housing. The plate has a fluid channel between a fluid inlet and a fluid outlet, a supply duct to supply the plate with fluid and a discharge duct, a casing defining the housing(s) and receiving the heat exchange plate and the supply and discharge ducts. The system includes a fluid collecting box arranged to collect fluid from a possible fluid leakage at the junction between the fluid inlet and the fluid outlet of the plate and the associated supply and discharge ducts, so as to prevent said leaked fluid from dripping into a bottom of the casing.

A vapor chamber that includes a housing having a first sheet and a second sheet that oppose each other and that are joined to each other in a peripheral region of the housing; a working liquid enclosed within the housing; and a wick structure on an inside surface of the first sheet or the second sheet. In the vapor chamber, the wick structure includes multiple protruding portions and a grid portion integral with the protruding portions. In addition, surfaces of the protruding portions and a surface of the grid portion opposite the inside surface of the first sheet or the second sheet are positioned on a same flat surface.

A fluid control device includes a housing having plural surfaces defining a cavity within the housing. The housing includes an inlet to receive a fluid mixture and an outlet to direct the fluid mixture out of the housing. The fluid mixture includes a fluid combined with debris. A structure array is disposed within the cavity and includes plural structures. Each of the plural structures includes a first surface coupled with an internal surface of the housing and a second surface disposed a distance away from the internal surface of the housing. The structure array includes a first portion and a second portion. The first portion is configured to interfere with the fluid mixture to separate at least some of the debris from the fluid, and the second portion is configured to direct the fluid and at least some of the debris toward the outlet.

An evaporator includes a cold plate configured to extract heat from one or more heat loads in proximity to the evaporator. The cold plate includes a housing, and a plurality of channels disposed through the housing, with at least one of the plurality of channels being a meandered channel.
