PURPOSE:To enable to easily imbed the underground heat exchanger under the ground by a structure wherein the underground heat exchanger is formed to a flat body, the tip of which is sharp-edged. CONSTITUTION:A main body part 1a consists of a narrow flat form with its sharp-edged tip 1b and its heat-exchange parts 4a and 4b, in which flow passage 6 is constituted by being partitioned with flow guide plates 5 and provided an outflowing and an inflowing ports 2a and 2b at its opposite ends. Said main body part 1a is imbedded in a groove dug in the ground of a building 7 in order to serve as the heat exchanger A. The heat exchangers A thus imbedded under the ground are connected to a solar heat collector 10 and the like. |
