WIPO Patent Application WO/2012/091266
Kind Code:
A3
Abstract:
Provided are a geothermal exchanger including a capillary-type heat pipe, an apparatus for preventing icing on a road/bridge, and a geothermal cooling and heating apparatus. The geothermal exchanger includes: a heat exchange part disposed adjacent to the ground so as to absorb heat from the ground or discharge heat to the ground; and a capillary-type heat pipe for transferring heat, in which a working fluid is injected, one side of the heat pipe for transferring heat being disposed adjacent to the heat exchange part so as to transfer heat, and the other side thereof being buried underground. When the surface of the ground is warmer than below the ground, the heat pipe for transferring heat transfers heat from the heat exchange part to below the ground, thereby storing the heat. When the ground surface is cooler than below the ground, the heat pipe for transferring heat transfers the heat from below the ground to the heat exchange part. Thus, natural energy from the ground may be accumulated underground in the form of thermal energy so as to increase the available heat in the earth. Further, providing the capillary-type heat pipe, which has a wide heat-transfer area and high heat-transfer efficiency, enables a loss of energy to be minimized and the thermal energy efficiency of the earth to be improved. In addition, the capillary-type heat pipe may be used alone without an additional operational device, such as a pump, so as to easily store the thermal energy and enable the easy installation and repair/maintenance of the geothermal exchanger.
