Title:
LARGE CAPACITY GEOTHERMAL HEAT EXCHANGE WELL
Document Type and Number:
WIPO Patent Application WO/2015/016143
Kind Code:
A1
Abstract:
[Problem] To provide a large capacity geothermal heat exchange well for which the capacity as a geothermal heat exchange well is increased and that has a structure that does not require a deep well. [Solution] A large capacity geothermal heat exchange well is characterized in that: a porous sleeve pipe is placed in a vertical hole opened in the ground with a fixed gap from the inner wall of a vertical hole; the gap region is made to be a permeable structure by way of filling the gap between the pipe and the inner wall of the vertical hole with a material, such as gravel, having good permeability; a heat exchange duct for allowing a heat exchange medium to flow is inserted into the pipe and then is connected to an inlet and a discharge port of equipment to be used; the ground water in the pipe is heated and caused to flow up by way of heat radiated by the heat exchange medium in the pipe by causing heat exchange medium to circulate between the duct and the equipment to be used; in addition, a convective flow occurs around the pipe by new ground water from the periphery flowing in the lower section of the pipe; and the radiated heat is widely dispersed to the surroundings by the occurrence of such convective flows, thereby significantly increasing the capacity as a geothermal heat exchange well.
