    The present invention is direct buried underground heat exchanger formed through reforming used engineering precipitating well. While the engineering precipitating well after completing normal precipitating task is refilled, U-pipe heat exchanger, spiral pipe heat exchanger or other tubular heat exchanger is inserted, well closing material is filled between the well wall and the heat exchanger, heat insulating material is filled near the well top, and the heat exchanger is connected to ground pipeline. By means of pumping out water and refilling water and the underground heat exchange, a closed geothermal heat pump type underground heat exchanger is formed.
