A heat exchanger is provided that includes a first tube/fin block, first headers arranged on both sides of the first tube/fin block, which first headers communicate with the tubes of the first tube/fin block, and a second tube/fin block having second headers arranged on both sides of the second tube/fin block, which second headers communicate with the tubes of the second tube/fin block, wherein the first tube/fin block having the corresponding first headers is an air-cooled low-temperature coolant cooler and the second tube/fin block having the corresponding second headers is an air-cooled refrigerant cooler, wherein the headers of the first tube/fin block arranged on a respective side of the tube-fin block and a header of the second tube/fin block are connected to one another.

Heat exchanger

A device for the exchange of heat between a first and a second medium with pairs of trays stacked one on top of the other in a stacking direction is provided, wherein a first flow chamber that can be flowed through by a first medium is provided between the two trays of at least one pair of trays or several pairs of trays and a second flow chamber that can be flowed through by a second medium is provided between two pairs of trays adjacent to one another, wherein the first flow chamber has first flow path with flow path sections that can be flowed through consecutively in opposite directions for the first medium, which are separated from one another by a division wall arranged between the at least two trays of the at least one pair of trays, and wherein the second flow chamber has a second flow path for the second medium.

Device for the exchange of heat and motor vehicle

A charge air duct for an internal combustion engine includes a housing with at least one entrance and at least one exit for charge air. A heat exchanger is arranged inside the housing to cool the charge air, a bypass is arranged on the housing to at least partially circumvent the heat exchanger and an actuator is arranged on the housing to influence the charge air flow. The charge air is guided from the entrance to the heat exchanger in a first position of the actuator and from the entrance to the bypass in a second position of the actuator, and the actuator at least partially reduces a cross-section of the charge air in a third position.
