With the increasing tension of energy and environment situation, renewable energy utilization is an effective way to solve relative problems. Shallow underground is considered as one of the most clean and environmentally friendly green energy technologies which can be used combination with underground thermal energy storage （UTES） and ground source heat pump （ GSHP）. In the paper, heat transfer characteristics and performance of coaxial tubes underground heat exchanger were analyzed. A heat transfer mode coupling heat transfer of flow in pipe with soil is advanced. Under the condition of no groundwater seepage flow in saturated soil, the outlet temperature of fluid and soil temperature are analyzed to explore the varying -time characteristics.
