    摘要: A thermoelectric conversion unit includes: a first fluid passage that has a first main surface and a second main surface and through which a first fluid flows; a second fluid passage through which a second fluid having a higher temperature than the first fluid flows; a pair of thermoelectric modules including a first thermoelectric module and a second thermoelectric module; and a pair of magnetic body portions disposed inside of or on a surface of the first fluid passage along a predetermined direction from the first main surface toward the second main surface. Each of the first and second thermoelectric modules generates an electromotive force based on a temperature difference between the first fluid and the second fluid. Magnetic bodies of the pair of magnetic body portions are disposed so that the same magnetic poles thereof face each other, and generate magnetic forces that repel each other.

    摘要: Integrated cooling device based on Peltier effect and manufacturing method thereof are provided. The device comprises one or more first heat dissipation structures around a device area. Each first heat dissipation structure comprises first N-type deep doped regions and first P-type deep doped regions arranged alternately, first vias, and first metal interconnection layers. The first vias are respectively located on two ends of each first N-type and each first P-type deep doped region. The first metal interconnect layers connect the first vias and such that the first heat dissipation structures are connected as a first S-shaped structure. When the first S-shaped structure is turned on, heat in the first N-type deep doped regions and the first P-type deep doped regions flows from a side close to the device area to its other side away from the device area, so as to realize heat dissipation in the device area.

    摘要: A metal junction thermoelectric device includes at least one thermoelectric element. The thermoelectric element has first and second opposite sides, and a first conductor made from a first metal, and a second conductor made from a second metal. The first and second conductors are electrically interconnected in series, and the first and second conductors are arranged to conduct heat in parallel between the first and second sides. The first metal has a first occupancy state, and the second metal has a second occupancy state that is lower than the first occupancy state. A temperature difference between the first and second sides of the thermoelectric element causes a charge potential due to the difference in occupancy states of the first and second metals. The charge potential generates electrical power.

    摘要: A transition dichalcogenide homojunction structure may include a lower high resistance layer including a plurality of PtX2 layers and an upper low resistance layer which includes the plurality of PtX2 layers and has different thickness and number of growth layers from the lower high resistance layer. And the lower high resistance layer and the upper low resistance layer may form a homojunction. The heat transfer characteristic of the lower high resistance layer may increase by the interface induced Seebeck effect with the upper low resistance layer. The transition dichalcogenide homojunction structure may generate the interface induced Seebeck effect at the interface of the homojunction to generate a thermal voltage. Further, the transition metal dichalcogenide homojunction structure may measure the Seebeck effect of the lower high resistance layer using the upper low resistance layer without separate measurement equipment.
