20090260775 | HEAT EXCHANGER, IN PARTICULAR AN EXHAUST GAS EVAPORATOR OF A MOTOR VEHICLE - A heat exchanger is provided, in particular an exhaust gas evaporator of a motor vehicle, including a heat exchanger block, a first axial terminating device and a second axial terminating device, in which the heat exchanger block has axial inlet openings and axial outlet openings, and in which means for forming a positive fit with the axial terminating devices are situated on the heat exchanger block, the means for forming the positive fit projecting at least partially over the axial inlet openings and/or over the axial outlet openings in the heat exchanger block in the axial direction, such that they may be situated radially next to contact shoulders of the axial terminating devices, thereby providing a heat exchanger that is particularly pressure-resistant in the radial direction. | 10-22-2009 |
20100025023 | HEAT EXCHANGER, EXHAUST GAS RECIRCULATION SYSTEM, AND USE OF A HEAT EXCHANGER - A heat exchanger, particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid and a second and third fluid that have different temperatures is provided. The heat exchanger comprises a block for separately conducting the first as well as the second and third fluid in a heat transferring manner. The block encompasses a number of ducts through which the first fluid can flow, a first chamber of a high-temperature part, through which the second fluid can flow and which accommodates the ducts, a second chamber of a low-temperature part, through which the third fluid flows and which accommodates the ducts, and a housing in which the first and second chamber as well as the ducts are arranged. Thus, a two-stage heat exchanger is provided at a low cost and keeps leakage between the high-temperature part and the low-temperature part low. Whereby the first chamber and the second chamber are separated from one another by means of a separation area that is mounted in a groove. | 02-04-2010 |
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 |
20110000657 | EXTRUDED TUBE FOR A HEAT EXCHANGER - An extruded tube for a heat exchanger is provided that includes two at least approximately parallel outer side walls that extend in a longitudinal direction and a transverse direction of the extruded tube and that are connected by two outer narrow sides in a vertical direction of the extruded tube, wherein at least one continuous web extends between the side walls in the longitudinal direction and in the vertical direction and separates at least two ducts of the extruded tube, and wherein at least one of the outer side walls has embossings that serve to form both bulged portions that project into the ducts of the side walls and also bulged portions that extend substantially in the transverse direction of the web, wherein the bulged portions of the at least one web have a controlled orientation with respect to the transverse direction. | 01-06-2011 |
