There were two types of underground heat exchange devices (heat exchangers): the double cylindrical thermal well type shown in Figure 1, and the cool tube type shown in Figure 2. Since both are buried in the soil as they are, when the soil hardens due to rainwater or ground vibration after embedding, a space is created between the outer surface of the heat exchanger 1 and the soil 4 that can hold air, and this insulation space Therefore, there was a problem that the heat exchange efficiency of the heat exchanger 1 decreased. In other words, the line A shown in Figure 3 is a curve showing the change in heat exchange capacity over time in an ideal state with no space between the heat exchanger 1 and the soil 4, and the line B is a curve showing the change in the heat exchange capacity over time, and the line B is a curve from the demonstration experiment. This is a curve showing the change in heat exchange capacity over time when there is a space obtained in .

(Structure) In the present invention, a heat exchanger 1 whose outer surface is surrounded by a flexible surrounding body 2 is buried in the soil, and then a thermosetting film is formed between the outer surface of the heat exchanger 1 and the surrounding body 2. This method relates to a method for burying a subterranean heat exchange device characterized by injecting thermosetting synthetic resin 3 under pressure and curing it with heat. This increases the adhesion between the exchanger and the soil, improving heat exchange efficiency.

均一かつスムーズに行なわれるようになる。Embodiment 1 What is shown in FIGS. 4 and 5 is a thermal well type heat exchanger 1 formed into a double cylinder structure with an inner cylinder 5 and an outer cylinder 6 that communicate with each other, and is installed vertically in the soil. is buried, and water or air is supplied from the pipe port 7 of the outer cylinder 6, and the water or air and soil heat are exchanged in the heat exchanger 1. Water or air for heating can be taken out from the pipe port 8 of the inner cylinder 5. The outer surface of the heat exchanger 1 is surrounded by a flexible enclosure 2 made of rubber such as butyl rubber or ethylene propylene rubber, and during construction, the heat exchanger 1 is buried underground while being surrounded by the enclosure 2. Buried. After this (preferably after a certain amount of time has elapsed), uncured and fluid heat of phenolic resin, epoxy resin, etc. A curable synthetic resin 3 is injected under pressure, and a surrounding body 2 is formed.
The opening 9 is closed, and hot air (c) is blown into the heat exchanger 1 to forcibly harden the thermosetting synthetic resin 3. As a result, the space between the heat exchanger 1 and the soil 4 is filled with the hardened thermosetting synthetic resin 3, the thermal resistance is reduced, and the heat exchange between the soil and the heat exchanger 1 is uniform. It will be done smoothly.
