Document Type and Number:
WIPO Patent Application WO/2017/003239
Kind Code:
A1
Abstract:
The present invention relates to a geothermal well insulating pipe, a geothermal well pipe assembly, a geothermal well heat exchange system, and a construction method therefor. The geothermal well insulating pipe according to the present invention is formed so as to be inserted into a geothermal well such that a heat transfer medium flows along the geothermal well, and comprises: an outer pipe part extended to the lower part of the geothermal well from the ground, and formed with a diameter, which is relatively smaller than that of the geothermal well, such that the outer pipe part is disposed to be spaced from the inner surface of the geothermal well; an inner pipe part having a length corresponding to the length of the outer pipe part and a comparatively smaller diameter than same, such that the inner pipe part is disposed to be spaced from the inner surface of the outer pipe part; and an insulating part formed by providing at least one insulating material in a space between the outer pipe part and the inner pipe part.
