Description of the Related Art A general road on which vehicles pass has a structure in which a roadbed is formed on a hearth and further asphalt pavement or concrete pavement is further provided thereon. In particular, a roadway or a roadside zone is paved with asphalt. Is usually the case. This asphalt pavement is composed of a surface layer and a base layer mainly composed of a heated asphalt mixture, the surface layer functions to prevent abrasion and shearing by traffic vehicles, and also functions to prevent penetration of rainwater, and the base layer joins the surface layer It functions to transmit the load evenly to the roadbed.

が生じる。The above-mentioned asphalt pavement is softened by a rise in temperature due to the characteristics of its material. However, under conditions of high solar radiation and high temperatures, especially in summer, friction between the asphalt pavement and solar heat or wheels is high. The road surface temperature becomes considerably high due to heat or exhaust gas heat. As a result, it may eventually soften to such an extent that it cannot sufficiently withstand the weight of the vehicle or the shearing force received from the wheels. In such a case, there is a problem that the road must be repaired frequently because a rut is formed on the road.

One end of the heat pipe is disposed below the road surface, and the other end of the heat pipe is disposed at a cooling location.

When the road surface temperature becomes higher than the temperature of the cooling point, the end of the heat pipe buried below the road surface becomes an evaporating section, whereas the end of the heat pipe located at the cooling point becomes a condensing section. Becomes That is, the working fluid sealed in the heat pipe evaporates at the end disposed below the road surface due to heat transmitted from the road surface, turns into steam, and moves toward the end on the cooling point side where the internal pressure is low. Flow. At that time, the turbine is rotated by the steam flow, and the generator is driven to generate electric power.

As described above, the working fluid sealed in the heat pipe transports heat held on the road surface to the cooling location, thereby suppressing an increase in the road surface temperature.
Therefore, the road surface is hardly softened so as not to withstand the weight of the vehicle and the shearing force of the wheels, and rut hardly occurs.

This will be described with reference to a specific example shown in FIG. FIG. 1 is a diagram showing an example of a heat pipe according to the present invention. The container 2 of the heat pipe 1 shown here is formed of a metal pipe having a circular cross section whose both ends are closed by end plates, and has a substantially L-shape as a whole. Further, a fluid that evaporates and condenses within a target temperature range such as pure water or alcohol in a vacuum degassed state is sealed inside the container 2 as a working fluid 3.

A shaft 6 arranged along the center axis of the container 2 is connected to the upper side of the rotor 5 in FIG.

Also,
The cord 10 connected to the generator 8 extends through the wall surface of the container 2 to the outside. That is, the rotor 5 is rotated by the steam of the working fluid 3 flowing upward from below in FIG. 1, and the input shaft 9 of the generator 8 rotates with this rotation. .

境界部分が好ましい。As shown in FIGS. 2 and 3, the heat pipe 1 having the above structure is laid below a road surface 12 made of asphalt pavement of a roadway 11. As shown in FIG. More specifically, the end of the heat pipe 1 on the side where the rotor 5 is provided is:
The entire road surface 2 is buried along a running direction of the vehicle below a portion where a rut is particularly likely to occur, that is, below the wheel contact portion 13. In addition, as a burial depth of these, as an example, a boundary portion between the roadbed 15 and the road surface 12 formed above the hearth 14 is preferable.

１２から地上に引き延ばされている。A side groove 16 formed of a U-shaped groove provided with a lid is provided at one shoulder of the roadway 11, and a relatively low temperature drainage 17 is constantly flowing at the bottom.
The other end of the heat pipe 1, that is, the generator 8
The end on the side where is provided is disposed at the bottom through the side wall of the side groove 16. That is, in this specific example, the drainage 17 is a cooling location. Further, as the heat pipe 1, an end disposed below the wheel grounding portion 13 serves as an evaporator 18 which receives heat from the road surface 12, and the side groove 1
The end arranged inside 6 is a condensing section 19 to be water-cooled. The cord 10 of the generator 8 is extended from the road surface 12 to the ground at an appropriate place.

等に有効利用される。Next, the operation of the above configuration will be described. The temperature of the road surface 12 gradually rises due to solar heat, frictional heat with wheels, and the like. However, when the temperature rises to some extent, a temperature difference occurs at both ends of the heat pipe 1, so that the heat pipe 1 is automatically transported by heat. To start. That is,
When the temperature of the wheel ground portion 13 becomes higher than the temperature of the drainage 17 in the side groove 16, the working fluid 3 evaporates due to the heat of the road surface 2 inside the evaporator 18 of the heat pipe 1. The vapor flows to the condensing section 19 having a low internal pressure. At this time, the steam of the working fluid 3 is
Of the rotor 5, the rotor 5 rotates at high speed. Accordingly, the input shaft 9 of the generator 8 is driven to rotate at high speed. As a result, power is generated. This electric power is effectively used for various cogeneration systems, for example.

る。以降、前述のサイクルが継続される。On the other hand, the steam of the working fluid 3 that has reached the condensing section 19 is deprived of heat by the waste water 17 and condensed. That is,
The heat held by the road surface 2 is released into the drainage 17 by the heat transport of the working fluid 3. The condensed working fluid 3 returns to the evaporator 18 by gravity or the capillary pressure of the wick, and is heated again to evaporate. Thereafter, the above-described cycle is continued.

Further, electric power can be obtained from the retained heat of the road surface 2 which has not been used at all in the related art, and effective use of energy can be achieved.

However, the present invention is not limited to the above-described specific example, and the heat pipe may be any type. The road surface may be made of concrete. In addition, the drainage 17 inside the side groove 16 is used as the cooling point. Alternatively, for example, the condensing part side of the heat pipe may be inserted into a U-shaped header pipe connected to the cold water circulation path.

Further, instead of the single-pipe type heat pipe shown in the above specific example, a loop-type heat pipe in which the evaporating section and the condensing section are connected by the vapor flow path and the liquid flow path can be adopted.

One end is located below the road surface, and the other end is located at a cooling point, so that asphalt pavement on the road surface does not soften, preventing the occurrence of ruts, and thus extending the period of road renovation and maintaining costs Can be reduced. In addition, electric power can be obtained from the thermal energy possessed by the road surface, which has not been used conventionally, and the energy can be effectively used.
