Patent
Behr GmbH and Co. KG | Date: 2016-02-29

A heat exchanger for a motor vehicle is provided having at least one block formed by tubes arranged parallel to one another and by fins arranged between the tubes. The tubes form multiple first flow ducts through which a first fluid can flow. The regions between the tubes form multiple second flow ducts through which a second fluid can flow around the tubes. The heat exchanger also has a first collecting box with a first fluid port and a second collecting box with a second fluid port. The first flow ducts are in fluid communication with a first cooling circuit via the first fluid port, the second fluid port, and the collecting boxes. The first collecting box or the second collecting box also has a third fluid port that, together with its respective collecting box and further fluid port, are in fluid communication with a second cooling circuit.

A heating device is provided with plates stacked one on top of another. At least one first fluid channel is formed in a fluid-tight manner between a first plate package with a first and a second plate. An electrical heating element is arranged between a first plate of the first plate package and an additional plate. The electrical heating element is accommodated between the two plates in a sealed manner and is electrically insulated, wherein an inlet-side and an outlet side fluid connection of the first fluid channel is arranged on the second plate of the first plate package. The electrical heating element has a connection device for electrical contacting, which is connected to the electrical heating element and protrudes through a window in the second plate of the first plate package, wherein the fluid connections and the window are arranged adjacent to opposing lateral edges of the second plate.


A combined intake and exhaust manifold (1) for a thermoelectric temperature control device includes an outer manifold case (2) that partially encases a first case interior (3), and an inner manifold case (4) provided in the first case interior (3), which partially encases a second case interior (5). The outer and the inner manifold cases (2, 4) have a joint connection side (6) for connecting a fluid line (17a, 17b). The manifold further includes at least one first flow-through opening (7a, 7b) for introducing or discharging a fluid into or out of the first case interior (3) and at least one second flow-through opening (8a, 8b) for introducing or discharging the fluid into or out of the second case interior (5) on the connection side (6).


Patent
Behr GmbH and Co. KG | Date: 2015-07-24

An exhaust-gas heat exchange, in particular for use in the exhaust tract of a motor vehicle, having a housing and having a first flow duct through which a first fluid can flow and which is received at its end regions in tube plates, wherein the first flow duct and the tube plates are surrounded by the housing in such a way that the housing forms a second flow duct through which a second fluid can flow, which second fluid can flow around the first flow duct, having a first diffuser which conducts the first fluid into the first flow duct and having a second diffuser which conducts the first fluid out of the first flow duct, characterized in that the exhaust-gas heat exchanger has, at at least one of its end regions, an at least partially encircling first flange which is formed in one piece with the exhaust-gas heat exchanger.
