Abstract: The invention relates to a thermoelectric module comprising a metal housing element and a ceramic layer that is applied to the metal housing element. The thermoelectric module further comprises an additional housing element arranged on the side of the metal housing element which is provided with the ceramic layer, the additional housing element and the metal housing element being joined to form a fluid-tight housing. The thermoelectric module finally comprises at least one thermoelectrically active material which is arranged inside the fluid-tight housing.

Abstract: A thermoelectric heat exchanger for heating or cooling a medium, that includes at least one first tube for carrying a first medium and at least one second tube for carrying the first medium. The second tube being arranged substantially parallel to the first tube. The thermoelectric heat exchanger also has a casing element that is interposed between the first and the second tube, the casing element comprising a first casing part that is connectable to the first tube and at least one second casing part that forms a fluid channel for a second medium. A thermoelectric element for heating or cooling the first or second medium is interposed between the first and second casing part, the thermoelectric element being closed relative to the first and/or the second medium in a fluid-tight manner via the casing element.

Abstract: A heat exchanger for exchanging heat between two media in a vehicle is provided. The heat exchanger includes at least one tube, especially a double-walled tube for carrying a first medium of a first temperature, a thermoelectric material being disposed on an inner wall of the tube, and at least one guide sheet, connected to the at least one tube, for carrying a second medium of a second temperature. The at least one guide sheet is designed to carry the second medium to the outer wall of the at least one tube to allow the exchange of heat between the first and the second medium.

Abstract: A thermoelectric unit for electrically interconnecting a plurality of thermoelectric modules. The thermoelectric unit includes a first thermoelectric module having a plurality of interconnected thermoelectric elements, the first thermoelectric module being interposed between a main surface of an inner flat tube and a main surface of an outer flat tube of a double-walled cooling tube, a second thermoelectric module being interposed between a second main surface of the inner flat tube and a second main surface of the outer flat tube of the double-walled cooling tube and/or between a main surface of an inner flat tube and a main surface of an outer flat tube of a second double-walled cooling tube, and an electrical connector designed to connect the first thermoelectric module to the second thermoelectric module in an electrically conducting manner.

Abstract: An exhaust cooler for a combustion motor is provided that includes a flow path for guidance of the exhaust from a combustion motor, wherein the flow path has a wall to separate the exhaust gas flow from a cooling fluid and wherein heat is exchangeable via the wall between the exhaust and the cooling fluid, wherein the wall is covered at least partially by a flexible thermoelectric film.
