The invention discloses a
loop heat pipe type terrestrial heat exploitation
system with adjustable and controllable working medium circular flow. The
loop heat pipe type terrestrial heat exploitation
system comprises a casing
pipe type
loop heat pipe, an
earth surface heat exchanger and a
liquid storage box. The
earth surface heat exchanger and the
liquid storage box are both located on the ground. The casing
pipe type loop
heat pipe comprises an
evaporation section, a heat insulation section and a
backflow section. The
evaporation section is located in a high temperature heat reservoir. The
earth surface heat exchanger is provided with a condensation section, and the condensation section and the outside carry out heat exchange. A one-way valve or a steam pump is arranged between the heat insulation section and the condensation section. A one-way
throttle valve is arranged between the
liquid storage box and the
backflow section. The
evaporation section, the heat insulation section, the condensation section, the liquid storage box and the
backflow section are communicated in sequence end to end. Working medium fluid of the liquid storage box enters the evaporation section through the backflow section, and the liquid working medium fluid entering the evaporation section generates film boiling after absorbing heat. According to the loop
heat pipe type terrestrial heat exploitation
system, the working medium fluid of the liquid storage box passes through the backflow section, the
liquid phase backflow mode and the boiling mode of the evaporation section are controlled, the effective
filling factor of the terrestrial
heat pipe can be adjusted in real time, and therefore terrestrial
heat energy is stably and efficiently extracted.
