The technical outcome of the proposed geothermal energy device is to increase its efficiency (CE), to simplify and cheapen the construction. The geothermal energy device contains downstream and upstream pipes, which are filled with fluid thermal agent and placed in the borehole, which is unilaterally closed from the ground surface; the pipes are connected to each other with a heat exchanger in the depth of the borehole. The downstream pipe is equipped with several mechanical non-return valves; on the same pipe there is also installed a down pushing pump of the thermal agent (e.g. isobutane). The end of the upstream pipe on the ground surface is directed towards the condensation type steam turbine, equipped with the controlled (e.g. electromagnetic) valve, and turned towards the mentioned turbine by the Laval nozzle. The energy device additionally contains the device of the frequency/duration control to lock and unlock the mentioned controlled valve.
A geothermal energy device comprises a downward and an upward pipe placed in a borehole, unilaterally closed only from the ground surface that are filled with a fluid thermal agent and connected to each other with a heat exchanger in the depth of the borehole, the downward pipe is equipped with at least one, or several sequential mechanical non-return valves, and on the downward pipe on the ground surface there is also installed a down pushing pump for the thermal agent and its steam condensate, and the end of the upward pipe on the ground surface is connected with a steam turbine, which is connected to the pump by means of a pipeline and a steam condenser for condensation and delivery to the pump of exhaust steam passed through the turbine, characterized by that the ending of the upward pipe is connected with the turbine by means of an impulse accelerator consisting of a controlled valve provided to convert the thermal agent from liquid to gaseous phase, a control device which manages the valve open-close duration and frequency in order to oscillate steam of the thermal agent at a resonant frequency, and a turbine-directed nozzle that accelerates steam of the thermal agent that is sprayed through the valve.
