Document Type and Number:
Japanese Patent JP2015034664
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an underground installation type heat exchanger capable of carrying out attachment work and detachment work for a helical air guide member quite easily and promptly.SOLUTION: The present invention provides an underground installation type heat exchanger buried in the ground for implementing heat exchange between a heat medium and earth thermal, including: an air circulation duct in which air as the heat medium circulates; an air flow inlet that opens on one end of the air circulation duct; an air flow outlet that opens on the other end of the air circulation duct; and a helical air guide member provided at least in a part of an interior of the air circulation duct, the helical air guide member being formed out of a rubber tube expandable/contractible in response to a quantity of gas filled inside.
