Thermoelectric generator using superconducting fluid for heat transfer

Abstract

The invention provides a thermoelectric generator using superconducting fluid for heat transfer, and belongs to the field of development and utilization of new energy techniques. The thermoelectric generator using superconducting fluid for heat transfer is characterized in that hot fluid flow into a hot fluid inlet pipe (1), is diverted to enter branch pipes and then is diverted to enter a hot fluid heat exchanger module (5a), in the hot fluid heat exchanger module (5a), heat is transferred to the two planes of the hot heat exchanger module (5a) through the superconducting fluid, semiconductor thermoelectric generating sheets are placed in parallel or in series on the planes to form high-temperature end surfaces, the heat of the high-temperature end surfaces is transferred to low-temperature end surfaces through the thermoelectric generating sheets, and the low-temperature end surfaces are in contact with cold ends for heat dissipation; the hot fluid which flows through the hot fluid heat exchanger module (5a) flows out of a hot fluid outlet pipe (2); cold fluid flows into a cold fluid inlet pipe (3) and flows out of a cold fluid outlet pipe (4) to form the cold ends on the surfaces of a cold fluid heat exchanger module (5b); and the semiconductor thermoelectric generating sheets (9) and the cold and hot end surfaces of the heat exchanger module (5) are alternately arranged to generate temperature difference to generate power. The invention provides a method for generating power in a large scale by using steam, flue gas, industrial waste gas, terrestrial heat, solar energy and the like. The method is not only energy-saving, but also environmental-friendly.

AI Technical Summary

Problems solved by technology

The thermal conductivity of the gas medium is very small, and the thermal conductivity is low

Although the thermal conductivity of the oil medium is slightly larger, the cost is relatively high, and it is not suitable for wide use.

The most widely used is the water medium, its disadvantage is that the thermal conductivity is small and the heat transfer is slow

In addition, the water medium often contains impurities, which are easy to scale and corrode metal pipes, especially after the formation of scale seriously affects heat transfer.
