  • Coaxial ground heat exchanger and ground heat exchange system including the same
    Patent number: 10088199
    Abstract: Disclosed is a ground heat exchange system including a heat exchange pipe including a borehole surface and an inner pipe to be inserted into the borehole surface, and installed to penetrate the ground, a circulation pump configured to inject a fluid between the borehole surface and the inner pipe and discharge a heated fluid from the inner pipe, a heat exchanger configured to exchange heat using the fluid discharged from the inner pipe, and at least one wing portion disposed between the borehole surface and the inner pipe and configured to reduce heat transfer between a fluid flowing between the borehole surface and the inner pipe and a fluid flowing in the inner pipe.
