Document Type and Number:
WIPO Patent Application WO/2018/014608
Kind Code:
A1
Abstract:
A novel steel-tube energy-pile for improving the utilization efficiency of shallow geothermal energy, and a manufacturing method therefor. The novel steel-tube energy-pile for improving the utilization efficiency of shallow geothermal energy comprises a steel-tube pile (1), a heat transfer pipe (2), a heat transfer pipe sleeve tube (3), an air conditioning system, a semiconductor thermoelectric power-generating system and a semiconductor thermoelectric heat dissipation and power generating system (22); the air conditioning system comprises a heat exchanger (10); the liquid in the heat transfer pipe (2) first exchanges heat with the soil, then regulates, by means of the heat exchanger (10) provided above the heat transfer pipe (2), the indoor air temperature in a building; the power energy generated by the semiconductor thermoelectric power-generating system and generated by the semiconductor thermoelectric heat dissipation and power generating system (22) is supplied to a electrical device above the surface of the earth. This system, using semiconductor thermoelectric power generation technology, generates power by means of a temperature difference between the liquid in the heat transfer pipe (2) and the soil; the energy generated by the thermoelectric heat dissipation and power-generating system (22) supplies a driving force to an underground heat dissipation pipe, the energy generated by the thermoelectric power generating system supplies a driving force to a low-power water pump in the air conditioning system, thereby increasing the cycle flow speed of the liquid in the heat transfer pipe, improving the heat cycle efficiency and heat exchange efficiency of the heat transfer pipe of the energy pile.
