Carry out heat exchange is looked like in a kind of underground heat convertibility system, by bedrock underground water and underground heat or by forming drilling and ground horizon d or water-bearing layer, geothermal heat exchange systems of the invention include: that suction pipe is formed longitudinally in and penetrates into underground water in polar bear hole to pump underground water with the tool of carrying water last; The heat exchanger of formation carries out heat exchange and thermal energy possesses underground water by it and passes through suction pipe to absorb; With, discharge pipe discharge Groundwater formation, there is critical heat and heat exchange unit, pass through polar bear hole. Suction pipe include: filter have multiple perforations hole, and with implement pump and the external straw of carrying water; At a certain distance from form external component, and with one or more from suction pipe and implement pump of carrying water, to support the inner surface close to filter, and keep being far from filter and implement pump of carrying water between the state. The implement pump insertion ground of carrying water of durability can be improved in the present invention, and enhances product efficiency and working efficiency. ;The 2016 of copyright KIPO submissions
