摘要： A method of using a thermoelectric generator for warming a transmission on a vehicle having an internal combustion engine is provided. The method includes starting the internal combustion engine, thereby generating a hot exhaust gas; circulating coolant through a heating loop in fluid communication with the internal combustion engine and the thermoelectric generator; passing the hot exhaust gas through a hot-side of the thermoelectric generator and circulating the coolant through the cold-side of the thermoelectric generator, thereby transferring heat from the hot exhaust gas to the coolant and generating an electric current; and selectively powering an electric heating element with the electric current. The electric heating element is in thermal communication with a transmission fluid of the transmission. The coolant is circulated through the thermoelectric generator, by an auxiliary coolant pump powered by the electrical current, for a predetermined length of time after shutdown of the internal combustion engine.

摘要： A system for recovering electrical energy and water from exhaust gasses. The system includes a thermoelectric generator to produce electricity from the waste heat of the exhaust gasses of internal combustion engines and the like. The exhaust is cooled by the thermoelectric generator, air cycle machine and other heat absorbing devise which, through work, reduce the exhaust gas temperature and promote condensation of the water.

摘要： The invention relates to an energy recovering assembly (1) and a method of providing the same for extraction of electric power. The assembly comprises a first array (2) of tubes (6) and a second array (3) of tubes (13). The tubes (6) of the first array (2) are interdigitated with the tubes (13) of the second array (3), such that two tubes (13) of the second array (3) are arranged between two successive tubes (6) of the first array (2), or such that two tubes (6) of the first array (2) are arranged between two successive tubes (13) of the second array (3). Thermo electric modules (4) are received in gaps (7) between adjacent tubes (6; 13) of the first (2) and second arrays (3). Fixation arrangements (5) are received in interspaces (X) between two tubes (6; 13). The fixation arrangements (5) are operable between a first state in which the fixation arrangement (5) is insertable in the associated interspace (X), and a second state in which the fixation arrangement (5) is adapted to exert a pressure on the two tubes (6; 13) in the associated interspace (X), forcing each of the two tubes (6; 13) towards the thermo electric modules (4) and towards the successive tubes (6; 13) adjacent the thermoelectric modules (4).

摘要： The present disclosure relates to thermoelectric devices useful for a range of thermoelectric applications (e.g., high temperature thermoelectric generation, fluid conditioning). Thermoelectric devices may include one or more heat exchangers (e.g., coolant heat exchanger(s)) and one or more thermoelectric layers adjacent to the heat exchanger(s). An enclosure may surround the thermoelectric layer(s) and heat exchanger(s), providing a barrier from outside fluid (e.g., hot fluid flow). The enclosure may conduct heat between the outside surroundings and the thermoelectric layer(s). The heat exchanger(s) may be spaced from and movable or slidable relative to the enclosure, which may accommodate for certain thermal expansion effects. The enclosure may include a conformable surface adapted to conform substantially to the shape of the thermoelectric layer(s) (e.g., when a vacuum is applied). One or more thermally conductive members (e.g., fins) may extend from the conformable enclosure. Various embodiments of a thermal switch are also described.

摘要： A thermoelectric generator for a motor vehicle may include a plurality of first stacking disks and a plurality of second stacking disks. The plurality of first stacking disks and the plurality of second stacking disks may be alternately stacked in a stacking direction and may each be shell shaped. The alternately stacked plurality of first stacking disks and second stacking disks may form a plurality of stacking disk pairs. The plurality of stacking disk pairs may each include a first stacking disk and a second stacking disk adjacent to the first stacking disk in the stacking direction. The first stacking disk and the second stacking disk may define a gas path. At least one intermediate space may be defined between adjacent stacking disk pairs. At least one tubular body may be disposed within the at least one intermediate space and may define at least one coolant path. The gas path may be traversed by a gas having a first temperature higher than a second temperature of a coolant flow through the at least one coolant path. At least one thermoelectric module having at least one thermoelectrically active element may be interposed within the at least one intermediate space between the gas path and the at least one coolant path. The thermoelectric module may include a hot side in thermal contact with the gas path, and a cold side in thermal contact with the coolant path.
