Abstract: A stacked-plate heat exchanger may include a first stacked-plate pack and a second stacked-plate pack. Each pack may have a plurality of stacked plates placed side by side and connected to one another, and a base plate via which at least one of inflow and outflow of a coolant may take place. The first and second stacked-plate packs may be connected to one another with the base plates lying against one another. The stacked-plate heat exchanger may also include a holder that holds the first and second stacked-plate packs exclusively on the two base plates. The first and second stacked-plate packs may each be directly connected to at least one of a coolant inlet and a coolant outlet via the respective base plates.

Abstract: An exhaust gas cooler may include a plurality of stacked disc pairs. A first flow chamber for a coolant flow may be disposed between two discs of at least a first disc pair of the plurality of disc pairs. A second flow chamber for an exhaust gas flow may be disposed between two second disc pairs of the plurality of disc pairs arranged mutually adjacent with respect to one another. The plurality of stacked disc pairs may include at least one coolant inlet and at least one coolant outlet. The first disc pair may include a plurality of coolant inlets and a plurality of coolant outlets surrounding an edge of the first disc pair to facilitate peripheral edge cooling.
