Title:
The manufacturing method of a subterranean heat exchanger, and a subterranean heat exchanger
Document Type and Number:
Japanese Patent JP5962232
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an underground heat exchanger which can suppress degradation of efficiency of heat exchange.SOLUTION: An underground heat exchanger 10, which is buried in the ground and is used, includes: circulating water piping 40 having a going pipe 31 which flows circulating water from a pile head side to a pile tip end side of a steel pipe pile 11, a return pipe 32 which flows the circulating water reaching the pile tip end side through the going pipe 31 from the pile tip end side to the pile head side, and a folding part 33 which connects the going pipe 31 and the return pipe 32 deep in the ground; and a pile head cap 15 which separates a part 32a on the pile head side of the return pipe 32 and a part 31a on the pile head side of the going pipe 31. Direct contact of the part 32a on the pile head side of the return pipe 32 and the part 31a on the pile head side of the going pipe 31 can be prevented, and mutual thermal interference between the parts 31a, 32a can be suppressed. A temperature change of the circulating water exiting from the underground heat exchanger 10 by an effect of the circulating water entering the underground heat exchanger 10 can be suppressed.
