The invention relates to a plate-type heat exchanger having a plate block comprising partition plates which delimit flow channel layers between the plates. According to the invention, the partition plates have a solid or folded edge, which projects out of the plane of at least one main side of the partition plates at the edge side, along closed-edge regions which are spaced apart from one another in the peripheral direction by means of intervening open-edge regions. In the plate block, this solid or folded edge is joined in a fluid-tight manner to the opposite edge region of an adjoining partition plate and functions as a lateral boundary for the associated flow channel layer. Such heat exchangers may be used, for example, in automobiles and reactors of fuel cell systems.

The invention relates to a heat exchanger, particularly of cross-current design, through which at least two separate media can flow. It comprises plates which are stacked on one another and which are spaced apart from one another in some areas and are in contact with one another in other areas, so that flow paths are formed between respectively adjacent plates in a heat exchange region. The plates have apertures adjacent to the heat exchange region, and the plates are spaced apart from one another by means of shaped-out portions of the plates. Areas succeeding one another about the circumference of the plates have apertures, and these areas are alternately shaped out in opposite directions from the plane of the plates.

The device is used to cool a vehicle appliance, in particular a battery or a fuel cell, by means of a coolant. It has a plurality of identically designed cooling elements, through which coolant can flow, which can be brought into bearing contact to cool at least one component of the vehicle appliance. It includes a first cooling-element side and a second cooling-element side which is on the opposite side from the first cooling-element side. The cooling-element sides have connection openings, which form inlet and outlet openings for the coolant and are in communication with the interior space of the cooling element. In this arrangement, it is provided for the first and second cooling-element sides each to have at least two connection openings.

The invention relates to a heat exchanger of the crosscurrent type, through which at least two fluids flow, consisting of plates which are stacked one on the other between two cover plates and which are spaced from one another in regions and are in contact in regions, so that fluid paths are formed between them in a heat transfer region, and of inlet ducts and outlet ducts which are arranged laterally in duct regions and which are formed from inlet duct openings and outlet duct openings in the plates, at least one inlet duct and one outlet duct being fluidically connected to a group of fluid paths which are next but one. The object of the invention is to develop a heat exchanger of the type initially mentioned, in such a way that, while having at least the same operating reliability, it can be produced more efficiently and more cost-effectively and has a lower weight. In order to achieve this object, there is provision for the spacing of the plates to be carried out by means of shaped-out portions of the plates.

Heat transfer device of a stacked plate construction has a stacked plate construction consisting of alternately stacked flow duct plate units with flow duct openings and connection duct openings as well as connection cover plate units with connection duct openings provided such that two separate fluid flow systems are formed. The equal-sided connection duct openings overlap only by means of an interior portion with the equal-sided ends of the flow duct openings, whereas, by means of an exterior portion, while forming a respective connection conduit, they extend in the area outside the flow duct openings. This implements a compact plate stack construction with an optimal connection geometry for very low pressure losses.
