will be buried. A heat transfer liquid having a high boiling point, low freezing point, and low specific heat, such as ethylene glycol, is circulated through the cooling pipe 12 . This heat transfer liquid may be an aqueous solution, but it is advantageous to use a 100% liquid such as ethylene glycol because it can fully exhibit the properties of the heat transfer liquid, such as endothermic properties. Of course, the heat medium liquid may be water.

冷媒のフレオンは吸熱して蒸発するのである。As the cooling unit 14, various known units can be employed. For example, one in which Freon is circulated as a refrigerant between an evaporator with a heat exchange function and a condenser with a compressor can be used. The heat medium liquid circulating through the cooling vibe 12 passes through the evaporator of the cooling unit 14 and exchanges heat with the refrigerant, whereby the heat medium liquid radiates heat and is cooled, while the refrigerant Freon absorbs heat and evaporates. It is.
