Abstract: Device for heat transfer and method for making it, the device having a housing with a heat exchanger disposed within and completely enclosed by the housing having a receiving element and cover element integrated within receiving element. First fluid flows through heat exchanger to be cooled; another fluid flows around heat exchanger. Heat transfer elements are shaped as a plate of a first jacket element and a second jacket element as well as a fin element; each includes a throughflow sector for inflow and outflow of first fluid. Each throughflow sector is developed on a front face of heat transfer element. Fin element has a lesser dimension in a longitudinal direction than jacket elements and is disposed therebetween such that in the proximity of a second front face, located distally to first front face, a free region is developed for deflecting direction of flow of first fluid.

Abstract: An exhaust gas cooler (10) comprises at least one exhaust gas channel (16) defined by at least one wall that, at the inlet (12), comprises at least one edge substantially perpendicular to the direction of flow, and is distinguished thereby that at least one edge is covered by a cap (22) defining an air gap toward the edge. An exhaust gas recirculation system comprises at least one such exhaust gas cooler.

Abstract: A heat exchanger is disclosed for the exhaust gas train of a motor vehicle. The heat exchanger includes a bundle of separately formed exhaust gas carrying exchanger tubes that is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outside of the exchanger tubes. A bandage is disposed on the bundle of exchanger tubes mechanically connecting a plurality of the exchanger tubes to militate against an oscillation of the exchanger tubes.

Abstract: A heat exchanger for an exhaust gas train of a motor vehicle with an exhaust gas carrying exchanger tube that is formed separately and is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outer surface of the exchanger tube. The housing includes a housing portion that forms one common mechanical interface for connecting the heat exchanger to the exhaust gas train and a coolant circuit of the motor vehicle.

Abstract: A heat exchanger is disclosed for the exhaust gas line of a motor vehicle including at least one exchanger tube that is formed separately and disposed in a closed housing formed separately, a coolant flowing through the housing and around the outside of the exchanger tube. An inlet and/or an outlet of the exchanger tube are located outside the housing, wherein the exchanger tube is guided through a wall of the housing at a feed-through point in a coolant- and/or exhaust gas-tight manner. Additionally, a manufacturing method for the heat exchanger and an assembly tool which can be advantageously used in the method are disclosed.
