Patent number: 10502111Abstract: An exhaust system for an internal combustion engine, especially for a vehicle, includes an exhaust gas-carrying pipe (12) and a reactant release unit (14) for releasing reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying pipe (12). The reactant release unit (14) includes a reactant injection unit (20), a reactant delivery unit (18) delivering reactant (R) from a reactant reservoir to the reactant injection unit (20) and a heating unit (24) for heating reactant (R) being delivered to the reactant injection unit (20). The heating unit (24) includes an exhaust gas/reactant heat exchanger unit (26) for transferring heat, being transported in the exhaust gas (A), to the reactant (R).Type: GrantFiled: January 10, 2017Date of Patent: December 10, 2019Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Gerd Gaiser, Fabian Frobenius, Bernd Weller

Patent number: 9954157Abstract: A thermoelectric generator includes a first channel for passing a warm fluid along a direction of flow, a second channel for passing a cold fluid, a plurality of thermocouple elements disposed along the direction of flow between the first and second channels, a first member includes portions disposed between the elements and the first channel and associated with the individual elements for providing a heat coupling between the associated element and the first channel, and a second member including portions disposed between the elements and the second channel and associated with the individual elements for providing a heat coupling between the associated element and the second channel. The sum of the thermal resistances of those portions that are associated with a first element positioned upstream of a second element is bigger than the sum of the thermal resistances of those portions that are associated with the second element.Type: GrantFiled: June 8, 2017Date of Patent: April 24, 2018Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Gerd Gaiser, Fabian Frobenius, Matthias Hense

Patent number: 9709350Abstract: A heat exchanger (5) includes a housing (31), which contains a tube (32) and has a jacket (33), which surrounds the tube (32) while forming a ring channel (34). A primary inlet (35) and a primary outlet (36) are connected to one another fluidically via a primary path (37) carrying a primary medium through ring channel (34) and via a bypass path (38) carrying the primary medium through the tube (32). A control device (39) controls the flow of the primary medium through the primary path (37) and the bypass path (38). A secondary inlet (42) and a secondary outlet (43) are connected to one another fluidically via at least two secondary paths (44) for carrying a secondary medium. The primary path (37) is coupled with the secondary paths (44) in a heat-transferring manner with the media separated from one another.Type: GrantFiled: September 13, 2013Date of Patent: July 18, 2017Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Gerd Gaiser, Markus Birgler, Matthias Feuerbach, Marc Hartmann, Jürgen Schweizer, Rouven Egger, Dimitri Penner, Fabian Frobenius
