産業上の利用分野
本発明は、ヒートパイプを埋設した地面温度制御装置の
改良に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a ground temperature control device in which a heat pipe is embedded.
従来の技術
道路面に降る雪を融かすために、一端に加熱部を有する
ヒートパイプを埋設することが提案された。しかしヒー
トパイプは道路面から１０〜３゜Ｃ１下方に埋設され、
アスファルトなどの道路材は熱伝導性があまり良くない
ので、加熱部で消費する熱エネルギーは少なくなかった
。BACKGROUND OF THE INVENTION In order to melt snow falling on roads, it has been proposed to bury a heat pipe having a heating section at one end. However, the heat pipe is buried 10 to 3 degrees C1 below the road surface.
Road materials such as asphalt do not have very good thermal conductivity, so a considerable amount of thermal energy is consumed in the heating section.

１力によって加熱部へもどる。In the working heating section, the working fluid in the heat pipe evaporates, and the vapor flows through the heat pipe as a high-speed vapor flow due to the vapor pressure difference, releasing latent heat of condensation. As a result, road materials such as asphalt around the heat pipe are heated or cooled, and a good thermal conductor such as a metal mesh plate or Kinkure powder is also heated or cooled. Since thermal conductors have better thermal conductivity than road materials such as asphalt, they can be heated or cooled faster than road materials, and the road materials surrounding the thermal conductors can be further warmed or cooled through the heated or cooled thermal conductors. This increases the temperature of the ground surface, melting snow that falls on the ground surface, and preventing asphalt from melting on the ground surface. After releasing the latent heat of condensation, the steam liquefies and returns to the heating section due to the capillary force and force of the wick provided in the heat pipe.
