The method of doing so has already been proposed.
しかし、このような方法によるときは、多量積雪や異常

ある。FIG. 5 is an explanatory diagram of an example of a snow melting device proposed as a means for solving such a problem. As shown in the drawing, the heat collecting and evaporating part (1a) of the heat pipe (1) is buried in the soil (10), and the heat radiating and condensing part (1b) of the heat pipe (1) is located on the pavement part (1b) of the road. It is arranged along the road surface. Further, a heater wire (20) is provided on the outer periphery of the heat collecting / evaporating portion (1a) of the heat pipe (1) as a means for compensating for the lack of heat quantity of geothermal heat. However, in such a snow melting device, the heater wire (20) is provided at the lower end of the heat pipe (1) as a means for heating the working fluid, so that heat is not radiated at a heat insulating part other than the part where heat is expected to be radiated. Inevitably, there is a problem of wasteful use of electric power and a problem that the heater wire cannot be easily replaced if it deteriorates.

Leave it at F. In this case, the heat collecting and evaporating section (1a) of the heat pipe (1) is heated by only the geothermal heat to evaporate the working liquid, and the heat radiating and condensing section (1b) radiates heat to be liquefied. This liquefied working fluid is transmitted through the inner wall of the heat pipe (1) and is accumulated in the intermediate liquid reservoir (2). By filling the amount of the working fluid so that the intermediate fluid (2) always overflows, the working fluid that overflows the intermediate fluid (2) is collected in the heat collecting evaporator (1a) of the heat pipe (1). Bring to reflux.

In this case, the flow of the working fluid in the heat collecting / evaporating section (1a) is the same as the case of the above-mentioned OFF, but the working fluid accumulated in the intermediate liquid reservoir (2) is heated by the heater wire (3). Evaporates,
The heat radiation amount in the heat radiation condensation section (1b) increases.

It stays only in the hydraulic fluid that flows down the inner wall, and it is easy to cause dryout of the part heated by the heater wire,
The heater wire is less effective.
