20130312803 | THERMO-ELECTRIC ARRANGEMENT - The invention relates to an arrangement comprising a thermo-electric generator having a hot side which absorbs heat from a heat source, a cold side which discharges heat to a heat sink, and electrical terminals for outputting electrical energy with an output voltage and an electric circuit with a maximum permissible input voltage, the inputs of which are connected to the electrical terminals of the thermo-electric generator. Such arrangements may be used, for example, in exhaust systems of motor vehicles for more efficient use of the energy. In order to provide such an arrangement, which can be connected to a heat source, in particular an exhaust system of an internal combustion engine, largely independently of the magnitude of the temperature difference between the hot and cold sides of the thermo-electric generator, it is proposed that the thermo-electric generator be configured in such a way that saturation of the output voltage occurs below the maximum permissible input voltage of the electric circuit, or when said maximum permissible input voltage is reached. | 11-28-2013 |
20130081665 | THERMOELECTRIC ELEMENT - A thermoelectric element includes at least one thermocouple comprising an n-doped and a p-doped thermal leg made of semiconductor material, wherein the thermal legs extend between a hot and a cold side of the thermoelectric element and different temperatures can applied and tapped between the hot and the cold side. In order to create a thermoelectric element haying a high thermal power density that nevertheless ensures sufficient mechanical stability using less semiconductor material, the thermoelectric effect and the support function of the block between two components is split. The support function is performed by a multipart support, while the thermoelectric effect is initiated by thermal legs disposed on the support, in particular designed as a thin film | 04-04-2013 |
20120152729 | Method for Producing Thermoelectric Layers - The invention relates to a method for producing thermoelectric layers by depositing thermoelectric material on a substrate by means of sputter deposition. In order to create a method for producing thermoelectric layers that are better suited for use in thermogenerators, and in particular have higher Seebeck coefficients, the production of a target made of thermoelectric material is proposed by mixing at least two powdered starting materials having a particle size from 0.01 μm-5000 μm, while coupling in energy and depositing the thermoelectric material from the target on the substrate by way of magnetron sputter deposition. | 06-21-2012 |
20110174351 | Module Having A Plurality of Thermoelectric Elements - A module having a plurality of thermoelectric elements electrically connected in series, each being made of at least one n-layer and at least one p-layer made of thermoelectric material with a pn-transition implemented along a boundary layer. A temperature gradient parallel to the boundary layer between a hot and a cold side of each thermoelectric element can be applied or detected. Resistances of the electrical contacts of the individual thermoelectric elements are reduced and the thermal connection to a heat sink or heat source is improved for generating a temperature gradient along the boundary layer. The substrate and the thermoelectric elements are produced in separate processes, and the thermoelectric elements are adhered to previously structured, thermally and electrically conductive regions of the substrate using different adhesives for the cold and hot side of each thermoelectric element. | 07-21-2011 |
20110005563 | Thermal Solar System - A thermal solar system including a collector that is connected to a heat sink, in particular a heat storage medium, by way of a solar circuit containing a heat exchange medium. To reduce overheating of the system during idling and to improve the efficiency of the solar system, the solar circuit is connected temporarily to at least one heat exchanger by way of a valve control unit disposed at a hot side of a thermogenerator receiving an inflowing heat flow. A thermal insulation reduces the exchange of thermal energy between the collector of a thermal solar system and the heat exchanger. | 01-13-2011 |
20110005562 | Thermogenerator - A thermogenerator including several thermocouples that are electrically connected together. The thermocouples are arranged between one hot side of the thermogenerator receiving a thermal flow and a cold side that is arranged at a distance from the hot side. The thermoelectric generator that at least temporarily uses the fed thermal energy efficiently. The thermoelectric generator can be designed as a module including a collector for a thermal solar system and the thermal carrier medium flowing through the collector is guided, at least temporarily, to a thermoelectric generator by a heat exchanger. | 01-13-2011 |
