| 20100199650 | DEVICE FOR EXHAUST GAS RECIRCULATION FOR A COMBUSTION ENGINE - A device for exhaust gas recirculation for a combustion engine is provided that includes an exhaust gas pipe configured to conduct exhaust gas and a channel configured to conduct air to the combustion engine. The exhaust gas pipe terminates in the channel, wherein the exhaust gas pipe, in an area of insertion in the channel exhaust, is in thermal exchange with a coolant from a coolant circuit. | 08-12-2010 |
| 20100218914 | EXHAUST GAS COOLER FOR A MOTOR VEHICLE - An exhaust gas cooler for a motor vehicle is provided that includes a first collector box on an inlet side and a second collector box on an outlet side, and a plurality of exchanger tubes extending between the collector boxes for exhaust gas to flow through. Air can flow around the exchanger tubes so as to cool the exhaust gas. At least one supporting member is attached to at least one of the collector boxes, a force produced by the thermal expansion of the exchanger tubes being passed into the supporting member. | 09-02-2010 |
| 20100282452 | DEVICE FOR THE EXCHANGE OF HEAT AND MOTOR VEHICLE - 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. | 11-11-2010 |
| 20100319887 | HEAT-EXCHANGING DEVICE AND MOTOR VEHICLE - An exhaust gas installation is provided that comprises an exhaust gas evaporator mounted downstream of an internal combustion engine of a motor vehicle. The exhaust gas evaporator has a sandwich-type structure wherein exhaust gas planes and coolant planes are alternately directly adjacently arranged, providing a very compact while very efficient exhaust gas evaporator. | 12-23-2010 |
