Summary:The utility model relates to a closed-loop heat pipe type underground heat exchanger, which is characterized in that a plurality of closed-loop heat pipes are embedded on the circumferential pipe wall of an overground circulating water inlet pipe, and one part of each closed-loop heat pipe is arranged in a circulating water main flow space formed by the overground circulating water inlet pipe and an overground circulating water outlet pipe. And the other part is arranged in a space formed by the geothermal water rising sleeve of the heat exchanger and the overground circulating water outer side water inlet pipe. According to the utility model, heat exchange between geothermal water and overground circulating water is realized by using the closed-loop heat pipe, and heat exchange of fluid in a mainstream space is realized by the closed-loop heat pipe on the basis of heat exchange only on a near wall surface originally through fluid circulation phase change in the closed-loop heat pipe. The heat exchange area i
