WO_2021014205_A1

Absstract of: US2022263006A1

A thermoelectric generator consists of circuits arranged in parallel rows, in which thermocouples in adjacent rows are facing each other by the same-named junctions, forming alternating narrow zones of hot and cold junctions. At least one of the layers is a layer of thermal energy thermocouples, the repeatability of the rows of circuits of which is two times less than the repeatability of the rows of circuits of thermocouples generating electricity. Hot and cold zones between the rows of thermocouple circuits of all layers of thermocouples generating electricity and hot and cold junctions of the rows of thermocouple circuits of thermal energy are superimposed, respectively, by tight contact on each other by junctions and substrates, ensuring internal heat exchange between them. In addition, the generator is provided with an external heat supply circuit to the hot zone area and a heat removal circuit from the cold zone area.

By using the gas turbine and closed cycle gas/(air or nitrogen) turbine in cascade way we can get the required heat for the heat exchanger chamber (for adding heat) in the closed cycle gas turbine, by using the heat diverted with exhaust gases from the open cycle gas turbine. Also we can get the heat from nuclear plant instead the open cycle gas turbine if it is available. When we get the very hot air to the heat exchanger chamber (for cooling the air) after leave the turbine in the closed cycle gas/air turbine, we use the sea water in multi heat exchanger to cool the air and use the heat make desalination of the sea water, so at the end we can produce fresh water and electricity by the open and closed gas turbine same time.
