Embodiment Construction

[0013] attached figure 1 The exhaust gas cooler shown is designed as a shell-and-tube heat exchanger, in which a plurality of parallel heat-exchange tubes 1 each configured as a flow path 1a are arranged in a housing or in other words through which the coolant flows. Inside the water jacket 3. The heat exchange tube 1 is passed by the exhaust gas of the internal combustion engine of the vehicle, and is used to transfer the heat of the exhaust gas to the coolant through the wall of the heat exchange tube 1 . The cooled exhaust gas is then fed at least partially on the inlet side to the internal combustion engine, for example in order to reduce nitrogen oxide emissions in a diesel engine.

[0014] A flexible thermoelectric film 2 is applied to the exhaust-gas-side inner side of the heat exchange tubes 1 in each case. In this case, the film 2 is in the best possible thermal contact with the wall of the heat exchange tube. Depending on the design of the foils, thermal and mecha...

Abstract

The invention relates to an exhaust cooler for a combustion motor, comprising a flow path (1a) for guidance of the exhaust from a combustion motor, wherein the flow path has a wall (1) to separate the exhaust gas flow from a cooling fluid and wherein heat is exchangeable via the wall (1) between the exhaust and the cooling fluid, wherein the wall (1) is covered at least partially by a flexible thermoelectric film.

Description

technical field [0001] The invention relates to an exhaust gas cooler for an internal combustion engine according to the preamble of claim 1 . Background technique [0002] Essentially what is being discussed is the use of waste heat from the internal combustion engine to operate thermoelectric elements, such as Seebeck elements. As a result, the overall efficiency of the internal combustion engine can be improved. In particular, the cost and structural complexity of the thermoelectric elements provided have hitherto prevented a range of solutions. [0003] DE 10 2006 055 120 describes a thermoelectric film which, due to its properties, can be maintained at high temperatures and, moreover, has sufficient mechanical flexibility for application to curved or angled surfaces. A thermoelectric film according to the invention is defined as a film according to DE 10 2006 055 120 A1. At least in suitable embodiments, the membrane has sufficient heat resistance for operation with ...
