Abstract
An underground heat exchanger has a bottomed tubular flexible bag body accommodated in an accommodation hole portion in the ground, and an outer tube accommodated in the accommodation hole portion, vertically extending along an outer surface portion of the bag body and communicating in its lower end with a lower end of the bag body. The outer surface portion of the hardening resin bag body can cover an inner wall portion of the accommodation hole portion in a closely contact state with the bag body being inflated. The bag body is hardened in the covering state, a lining tubular body formed by the hardening can form a liquid storage tank for storing a heat medium liquid in its internal space, and the outer tube is pinched between the outer surface portion of the bag body and the inner wall portion.
Claims7
An underground heat exchanger comprising:
- a bottomed tubular flexible bag body which is accommodated in an accommodation hole portion disposed in the ground in a vertical direction, and extends in the vertical direction;
- and
- an outer tube which is accommodated in the accommodation hole portion, extends in the vertical direction along an outer surface portion of the bag body and is communicated in its lower end with a lower end of the bag body,
- wherein the bag body is made of a hardening resin, the outer surface portion of the bag body can cover an inner wall portion of the accommodation hole portion in a closely contact state in a state in which the bag body is inflated, the bag body is structured such as to be hardened in the covering state, and a lining tubular body formed by the hardening is capable of forming a liquid storage tank for storing a heat medium liquid in its internal space, and
- wherein the outer tube is structured such as to be pinched between the outer surface portion of the bag body and the inner wall portion.

An underground heat exchanger comprising:
- a bag body having a bottomed tubular flexibility and made of a hardening resin, the bag body being accommodated in an accommodation hole portion which is provided on the ground in a vertical direction;
- and
- an outer tube extending along an outer surface portion of the bag body in the vertical direction and communicated its lower end with a lower end of the bag body, the outer tube being accommodated in the accommodation hole portion,
- wherein the outer tube is in a state of being pinched between a desired width portion of the outer surface portion of the bag body as seen from a circumferential direction and an inner wall portion of the accommodation hole portion, and the other portion than the desired width portion of the outer surface portion is in a state of covering the inner wall portion in a closely contact state,
- wherein the bag body is structured such as to be hardened in the covering state, and a lining tubular body formed by the hardening is structured such as to form a liquid storage tank which can store a heat medium liquid in its internal space,
- wherein an inner tube is structured such as to be arranged in an upper portion of the liquid storage tank in a state of sinking its lower end portion into the heat medium liquid within the liquid storage tank,
- wherein an upper end of the outer tube is structured such as to be connected to one end of a heat absorbing and radiating tube portion which is capable of radiating heat in an area where heat radiation is required and can absorb heat in an area where heat absorption is required, and an upper end of the inner tube is structured such as to be connected to the other end of the heat absorbing and radiating tube portion, and
- wherein a pump for circulating the heat medium liquid is interposed.
