GEOTHERMAL POWER GENERATOR Russian patent published in 2024 - IPC F24T50/00 F03G4/00 F03C2/02 

FIELD: renewable energy.

SUBSTANCE: invention relates namely to the devices designed to convert low-grade heat into electrical energy. A geothermal electric generator contains a circulation pump and an electric generator. A geothermal electric generator includes at least two high-pressure vessels, each of which is placed in a separate thermal jacket and equipped with a valve system. The thermal jackets of each vessel are equipped with three-way hydraulic switches, through which the high-pressure vessels are connected to two thermal circuits - lower and upper, equipped with circulation pumps. The valve system of each cylinder includes a three-way valve and an exhaust gas pressure reducer. The valve system is connected to the piston group with an electric generator.

EFFECT: ensuring a stable flow of working gas into the piston group (engine) of the generator, with the ability to adjust the power taken and eliminate the need for additional cooling of the working fluid after the phase of transfer of thermal energy to mechanical (electrical).
