Patent number: 9748465Abstract: A thermoelectric module (13), for converting thermal energy into electric energy, includes a plurality of leg pairs (26), which have each a p-doped semiconductor leg (27) and an n-doped semiconductor leg (28), which are contacted with one another electrically via metal bridges (29). At least one electrically insulating ceramic plate (30), which is arranged on a hot side (18) of the thermoelectric module (13) or on a cold side (19) of the thermoelectric module (13) and is flatly in contact with metal bridges (29) associated with this side (18, 19) and is fastened thereto. The pressure stability of the thermoelectric module (13) can be improved if the respective ceramic plate (30) is segmented, so that a plurality of ceramic plate segments (31) are arranged next to each other, which are each flatly in contact with a plurality of metal bridges (29) and are fastened thereto.Type: GrantFiled: June 21, 2013Date of Patent: August 29, 2017Assignee: EBERSPAECHER EXHAUST TECHNOLOGY GMBH & CO.

Patent number: 9574481Abstract: A heat exchanger (7) for an exhaust gas system (5) of an internal combustion engine (1) includes a thermoelectric generator (13) with plural thermoelectric elements (15) that each have a hot side (16) and a cold side (17). A heating channel (18) conducts a heating medium on the hot sides and a cooling channel (19) conducts cooling medium on the cold sides (17). The thermoelectric generator (13), the heating channel (18), and the cooling channel (19) are arranged adjacent in a stacking direction (20) and form a channel stack (21). A housing (8) that encloses an interior (22) accommodates the channel stack (21) and has medium inlets (9, 11), outlets (10, 12) and electrical connections (14). The thermoelectric elements are arranged in a double-walled intermediate bottom (15) that separates the cooling channel (19) from the heating channel (18), adjacent to said cooling channel, in regard to fluid flow.Type: GrantFiled: May 6, 2013Date of Patent: February 21, 2017Assignee: EBERSPÄCHER EXHAUST TECHNOLOGY GMBH & CO.

Patent number: 9416712Abstract: A heat exchanger, for an exhaust gas system (5) of an internal combustion engine (1), includes a thermoelectric module (13), converting thermal energy into electrical energy, having a hot side (17) and a cold side (18). A cooling pipe (15), for a cooling fluid, is arranged on the cold side (18) and a heating pipe (16) for a heating fluid, is arranged on the hot side (17). The cooling pipe (15) and the heating pipe (16) are stacked with the thermoelectric module (13) in a stacking direction (19) and form a stack (20). The heat transfer within the stack (20) is improved with at least one of the pipes (15, 16) being curved toward the thermoelectric module (13) at an outer pipe face (26) and with the thermoelectric module (13) curved toward the pipe (15, 16) at an outer module face (27) facing the particular pipe (15, 16).Type: GrantFiled: June 21, 2013Date of Patent: August 16, 2016Assignee: EBERSPÄCHER EXHAUST TECHNOLOGY GMBH & CO.

Publication number: 20160017785Abstract: A static mixer (12) for an exhaust system (7) for mixing a reducing agents with an exhaust gas flow (8). The static mixer (12) has a plurality of guide blades (14) for deflecting the exhaust gas flow (8). A reduced flow resistance is obtained when at least one of the guide blades (14) has a perforation (25) through which the exhaust gas flow (8) can flow.Type: ApplicationFiled: July 14, 2015Publication date: January 21, 2016Inventors: Andreas RESCH, Silvia CALVO

Patent number: 9163545Abstract: A heat exchanger (9), of e.g. an exhaust gas system (5) for an internal combustion engine (1), includes a thermoelectric generator (12) having a hot side (13) and a cold side (14) and including a heating tube (15) on a hot side of a heating device (10), and a cooling tube (16) on a cold side of a cooling device (11). The heating tube and the cooling tube are stacked on one another and form a tube stack (18), with the heating tube and the cooling tube extending parallel to one another in a longitudinal direction (19) of the tube stack. For energy efficiency, a housing (21) of the heat exchanger has a jacket (23) with an integral re-tensioning section (25) that is resiliently adjustable between a relaxed state and a tensioned state. The pre-tensioning section generates a pre-tensioning force (26) pressing the tube stack in a stacking direction (17).Type: GrantFiled: April 10, 2013Date of Patent: October 20, 2015Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Andreas Resch, Sebastian Leicht, Jörg Oesterle
