Abstract: A cooling plate for the battery cooling of a motor vehicle has a plate body including two plate elements, joined together by soldering and at least one cooling channel for the passage of a cooling fluid as well as a stiffening molding. The cooling channel and the stiffening molding are initially formed together continuously during the manufacture of the plate body by forming a channel in a plate element, by internal high pressure forming. In the soldering process, a channel portion of the channel sealed fluid-tight by a closing element in the form of a press soldering joint. This separates the channel into a cooling channel and a stiffening molding.

Abstract: A heat exchanger plate which has a plate body formed from at least two plate elements and at least one connecting piece for a cooling fluid. Plate body and connecting piece are joined together using soldering. The connecting piece has a joining portion which is joined in a receiving portion of the plate body formed between the plate elements. A solder resist limits the flow of solder when producing the solder connection. The solder resist is able to be formed by a sealing metal, which is arranged on the joining portion of the connecting piece in front of and/behind a solder material applied to the joining portion. The solder resist is able to be formed by an annular bead resting on the end face of the receiving portion.

Abstract: A cooling plate for battery cooling has a plate body formed from two plate elements and a connecting piece for a cooling fluid. The connecting piece has a connection section which is joined in a receiving section of the plate body formed between the plate elements. The connection section has two arcuate wall sections in cross section and two opposing, outwardly directed longitudinal webs. The receiving section has longitudinal grooves extending between the plate elements in the area of the joining plane. The longitudinal webs run in the longitudinal grooves.

Abstract: In order to produce a battery carrier which has a battery tray with a cooling plate, a tray plate and a cooling plate are joined to one another, wherein the cooling plate has at least one preshaped cooling duct. The tray plate jointly with the cooling plate is then formed by folding to produce the battery tray. During the folding of the tray plate and the cooling plate, a cooling duct section is bent around a bottom edge of the battery tray. The cooling duct is provided with connection elements via which a cooling fluid is supplied and discharged. During the course of the finishing, end shape-producing shaping of the cooling duct can also be performed. Internal pressure is applied to the cooling duct in order to restore the shape of the cooling duct which collapsed due to the forming.

Abstract: The disclosure relates to a battery holder for the receiving of a plurality of battery modules in an electrically driven vehicle. The battery holder may include a plurality of juxtaposed module receptacles, wherein each module receptacle is configured to receive the battery module, and a profile wall that defines the plurality of module receptacles, wherein a heat exchanger is configured to temper the battery modules is formed in the side wall, wherein the heat exchanger comprises a plurality of hollow channels that extend along the module receptacles.

Abstract: A method for producing a thermoelectric generator configured to be used in an exhaust system of a motor vehicle. The thermoelectric generator includes a plurality of tubular thermoelectric modules arranged in a housing and including external pipes, internal pipes, p-doped and n-doped thermoelectric elements, and external rings. The thermoelectric modules are separated from one another on a face side by pipe bottoms. The method steps include connecting, by a gas-tight connection, the external pipes with the housing and the pipe bottoms; applying an electrically insulating coating onto inside surface of the external pipes; sliding the internal pipes including the p-doped and n-doped thermoelectric elements, and the external rings into the external pipes; shrinking the external pipes and fitting the external pipes into the internal pipes.
