Patent number: 9145802Abstract: A heat exchanger (7) for an exhaust system (5) of an internal combustion engine (1), includes a heating tube (16) for carrying hot exhaust gas and a cooling tube (17) for carrying a liquid cooling agent. A thermoelectric generator (13) generates an electric voltage from a temperature difference and is arranged with the adjacent tubes in a stacking direction (18) to form a stack (21). A support tube (28) is supported in the stacking direction on wall sections (29) of the respective tube (16, 17), which wall sections mutually face each other, and is arranged in the respective heating tube (16) and/or cooling tube (17). Increased energy efficiency is achieved if at least two support tubes (28), which differ from one another by tube length and/or tube end (30) and/or by tube cross sections, are arranged in the respective tube (16, 17) at right angles to a longitudinal direction (31).Type: GrantFiled: August 19, 2013Date of Patent: September 29, 2015Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Jörg Oesterle, Angela Hettel, Ming Dong, Enver Kurpejovic, Anika Bürkle

Patent number: 9021795Abstract: The present invention relates to a heat transfer device, more preferably for an exhaust system of a combustion engine, preferentially of a motor vehicle, with at least one warm tube for conducting a fluid emitting heat, with at least one cold tube for conducting a fluid absorbing heat and with at least one thermoelectric generator for generating electric energy from a temperature difference, wherein a thermoelectric generator each is arranged between a warm tube and a cold tube. The efficiency of the heat transfer device is improved if the respective thermoelectric generator is in contact with the respective tube via a heat conducting material and if the respective heat conducting material is configured as shaped body.Type: GrantFiled: April 15, 2011Date of Patent: May 5, 2015Assignee: Eberspaecher Exhaust Technology GmbH & Co. KGInventors: Arnulf Spieth, Anika Bürkle, Ming Dong, Jörg Oesterle, Angela Hettel

Patent number: 8661802Abstract: The present invention relates to a flange plate for connecting exhaust pipes to a combustion engine, with at least two connecting sockets integrally moulded on the flange plate, on each of which an exhaust pipe can be fastened, and with a plurality of through openings for fixing the flange plate to the combustion engine. Thermal expansion effects can be better compensated if at least one of the connecting sockets is formed in a connecting region, which is surrounded by a slit penetrating the flange plate, wherein the respective slit comprises at least one interruption and the respective connecting region in the region of the respective interruption is connected to the remaining flange plate.Type: GrantFiled: July 8, 2011Date of Patent: March 4, 2014Assignee: J. Eberspaecher GmbH & Co. KGInventors: Ralf Riekers, Angela Hettel
