Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a thermoelectric power generation device, including a heat insulation board 1 and a heat conduction assembly 2 installed on the heat insulation board 1 . The heat insulation board 1 is a square plate made of heat insulation material, and four assembly holes 11 are opened on the upper surface of the heat insulation board 1, wherein the four assembly holes all pass through the heat insulation board 1 and are distributed in a rectangular array, and the four Each assembly hole 11 divides the upper surface of the heat insulation board 1 into a "Tian" shape. A piece of temperature difference sheet 12 is installed in the four assembly holes 11, and an annular support sheet 5 for placing the temperature difference sheet 12 is fixed on the inner wall of the groove of each assembly hole 11, so that the upper surface of the temperature difference sheet 12 serves as a heat conduction surface...

Embodiment 2

[0037] The embodiment of the present invention also provides an electric storage system, such as Figure 5 As shown, it includes a thermoelectric power generation device, wherein the thermoelectric power generation device adopts the thermoelectric power generation device provided by Embodiment 1 of the present invention, and the thermoelectric power generation device provides a stable output voltage. The power storage system also includes a battery. A booster module is connected to the output end of the thermoelectric power generation device, and the output end of the booster module is connected to the battery. Since the voltage directly generated by the thermoelectric sheet is usually relatively low, even if the integrated four-chip temperature difference Compared with the commercial voltage available for home appliances, the voltage generated by the thermoelectric power generation device is boosted by the booster module, and the boosted current is transmitted to the battery f...

Abstract

The embodiment of the invention discloses a thermoelectric generation device comprising a heat insulation board and a heat conduction assembly mounted on the heat insulation board. Four assembling holes are formed in the upper surface of the heat insulation board; and a thermoelectric piece is installed in each of the four assembling holes. The heat conduction assembly includes a plurality of heatconducting sheets that are connected in series to form a crawler belt shape; one end of the heat conduction assembly is connected to a heat generating source and the other end is connected with heatconducting surfaces of the four thermoelectric pieces so as to transfer the heat from the heat generating source to the heat insulation board. Besides, cold conducting surfaces of the four thermoelectric pieces are connected with a water cooling device externally, so that the temperatures of the heat conducting surfaces of the four thermoelectric pieces are higher than those of the cold conductingsurfaces and thus obvious and stable temperature differences are formed between the two sides of the four thermoelectric pieces. In addition, the embodiment of the invention also provides a power storage system comprising the thermoelectric generation device, a boosting module, a storage battery and an inverter; and the boosting module carries out boosting on the voltage generated by the thermoelectric generation device and the boosted power is stored into the storage battery, so that power supply of some electric appliances at home is realized conveniently.

Description

technical field [0001] The invention relates to the technical field of thermoelectric power generation, in particular to a thermoelectric power generation device and a power storage system. Background technique [0002] If two different metals in contact are kept at different temperatures, an electromotive force will be generated between the two different metals, and a current will be generated in the circuit composed of the two different metals. This is the Seebeck effect. The electromotive force generated by the Seebeck effect is a thermoelectromotive force, and the generated current is a thermoelectric current. The two different metals that are connected together and can generate thermoelectric force are called thermocouples, and thermocouples made of semiconductor materials have larger thermoelectromotive forces. Multiple thermocouples with large thermoelectromotive force can be connected in series to form a thermopile that can obtain a sufficiently high voltage. The th...
