The top defines at least one opening, on which at least one silicon dioxide layer is provided. The chamber is in a vacuum-tight state or maintains a positive pressure inert gas atmosphere therein. The jig structure for manufacturing heat dissipation unit can be used with a laser machining tool to provide a better environment and increased flexibility for laser machining or laser welding in manufacturing a heat dissipation unit.

The present industrial property right relates to a method for producing a cooling plate, to the cooling plate as such and to a battery system and an electric vehicle. According the method for the production of the cooling plate at least two flat metal sections are interconnected by laser beam welding.

To provide a vapor chamber with which distortion of a container is reduced regardless of the kind of the material of the container and generation of pin-holes in a melted part of the container is prevented. The vapor chamber includes a container having a hollow cavity part, the container being formed by laminating one tabular member and another tabular member facing the one tabular member; a working fluid enclosed in the cavity part; and a wick structure provided in the cavity part. An outer peripheral part of the cavity part is sealed by welding. A melted part formed by the welding runs through the one tabular member, while the melted part does not run through the other tabular member.

A method for producing a heat exchange tube having an inner turbulence insert for a heat exchanger may include providing an austenitic heat exchange tube and the turbulence insert. The method may also include inserting the turbulence insert into the austenitic heat exchange tube, brazing the turbulence insert and the austenitic heat exchange tube via induction brazing, and pressing the austenitic heat exchange tube onto the turbulence insert at least one of during the brazing and after the brazing.

A method of manufacturing a heat exchanger includes providing a first plurality of micro-tubes, wherein each micro-tube has a first side and a second side extending along a first axis, and providing a first plurality of fins, wherein each fin having a first base having a first face and a second face disposed opposite the first face. The method further includes disposing the first side of each micro-tube of the first plurality of micro-tubes on the first face of the first base of the first plurality of fins and joining an entire length of the first side of each micro-tube of the first plurality of micro-tubes to the first face of the first base of the first plurality of fins to define a first heat exchanger layer.

A method for producing a flat tube for a heat exchanger, in particular for a motor vehicle, having a first wall, a second wall opposite to the first wall, having a third wall connecting the first and second wall, having a fourth wall connecting the second and first wall, wherein the first and second wall are longer than the third and fourth wall, having an interior for a medium to flow through, wherein a turbulence insert is arranged in the interior, wherein the method comprises at least the following process steps: providing a plate materialforming the plate material into an intermediate tube in such a way that the plate material is crowned in at least two sections and the sections at least partially form the first and second wall of the flat tube and the intermediate tube forms an opening in the area one of the two third or fourth wallsproviding and inserting a turbulence insert into the interiorclosing the opening by means of a welding method.

A vapor chamber with a support structure and its manufacturing method are provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

A heat recovery device comprises a body inwardly delimiting an exhaust gas circulation passage and a heat exchanger. The heat exchanger includes a casing, a plurality of exhaust gas circulation tubes and at least one grate arranged in the proximal opening of the casing. The grate comprises a wall in which orifices are arranged for receiving tubes. The grate also has an upright edge protruding toward an inside of the heat exchanger, the upright edge being rigidly attached to the casing. The wall of the grate has, around the orifices, a planar surface turned toward the body. The body has an opening delimited by a flat edge pressed against the planar surface. The planar surface and the flat edge are rigidly attached to one another to be tight with respect to exhaust gases.

The present application discloses two-phase cooling devices that may include at least three substrates: a metal with a wicking structure, an intermediate substrate and a backplane. The titanium thermal module may be adapted for use in a mobile device, such as a portable device or smartphone, where it may offer compelling performance advantages. The thermal module may also have a metal layer which may act as a shield for radiation or an antenna for radiation, or may add mechanical strength to the thermal module.

This heat exchanger includes fluid circulation channels extending lengthwise along a first axis, and layers that are flat and superposed on one another along a second axis. To improve performance, each layer is made up of metal strips so the strips a layer all extend lengthwise perpendicular to the second axis and adjacent one another, without necessarily touching. Each channel is jointly defined by first through third layers, the second being intercalated, along the second axis, directly between the first and third layers so each channel is delimited by a face of the first and third layers and edges of the second layer running parallel to the first axis and transversely to the second layer, these edges being formed by strips of this second layer fusion-welded to the first and third layers in zones extending along the length of the channel and situated on either side of the channel.
