The present invention relates to a process for forming a metal component (20), the process comprising the steps of heating a metal blank (20) coated with a protective layer; cooling said metal blank (20) in a confined space (14), said cooling involving cooling by means of a gas, the gas being cooled by heat exchange with a cooling surface of a heat sink (22) inside said confined space (14), wherein a low frequency sound wave is provided into said confined space (14) in order to improve heat exchange both between the gas and a cooling surface of the at least one heat sink (22), and between the gas and the metal component (20), wherein the heated coated blank is cooled to a temperature below the melting point of the protective layer, and forming the coated blank to a component. The invention also relates to a production line for performing the process.

A heat exchanger device for a motor vehicle includes a main body, through which a temperature-control medium can flow, and a media-conveying device which passes through the main body and by which a medium to be temperature-controlled can be conveyed through the main body. As a result, the temperature of the medium to be temperature-controlled can be controlled by heat exchange with the temperature-control medium. The main body is produced in an integral injection molding process, as a result of which the main body is closed on the periphery and open-pored in the interior.

High heat flux furnace cooler comprise CuNi pipe coils cast inside pours of high purity (99%-Wt) copper. The depth of front copper cover over the pipe coils in the hot face to manufacture into the casting is derived from a projection of the thermal and stress conditions existing at the cooler's end-of-campaign-life. CFD and/or FEA analyses and modeling is used for a trial-and-error zeroing in of the optimum geometries to employ in the original casting of CuNi pipe coils in high purity copper casting. Individual pipe coil positions to cast inside a copper casting mold are secured with devices that will not melt, cause thermal shear stresses, or be the source of contaminations or copper defects. Pipe bonding to the casting results because the differential coefficient of expansions of the pipes' and the casting's copper alloys involved do not exceed the yield strength of the casting copper during operational thermal cycling.

A method of cooling a liner in a plasma chamber. A recycle gas is contacted with or passed through the liner to cool the liner and pre-heat the recycle gas. The pre-heated gas is then recycled through the plasma chamber to become part of the plasma forming process. The method further comprises the liner is graphite, the recycle gas passes through at least one cooling channel present in the liner, at least one of the cooling channels are covered with at least one removable liner/channel cover, carbon deposits are formed from the presence of hydrocarbons in the recycle gas, at least one channel is formed in a spiral cooling channel pattern, at least one channel is formed in a substantially straight cooling channel pattern, and a plenum to aid in the production of an even distribution of cooling gas in the channels.

Heat exchanger assemblies for electronic devices are disclosed. A heat exchanger assembly may include a heat transfer body that has a face that forms open passageways. A cover structure may be attached to the heat transfer body in a manner to enclose the open passageways, thereby forming a heat exchanger assembly that includes enclosed fluid conduits. In this regard, the enclosed fluid conduits may form complex and intricate patterns within the heat exchanger assembly that are tailored to the heat requirements of a particular application. Heat exchanger assemblies as described herein may be thermally coupled to a center waveguide section of a spatial power-combining device. The enclosed fluid conduits may be tailored based on locations of amplifiers within the center waveguide section to provide improved thermal operation of the spatial power-combining device.
