Heating pipe for preventing freezing of road using geothermal heat {HEATING PIPE FOR PROHIBIT ROAD FREEZING}

The present invention relates to a heating pipe for preventing road icing using geothermal heat, and more specifically, to prevent freezing of the road surface using ground heat in the ground, to prevent freezing of slopes and corners, and to promote safe operation in winter. It relates to a heating pipe for preventing road surface freezing.

Heating pipes for preventing road freezing have been developed to prevent freezing of winter roads and promote safe driving. As an example, Korean Laid-Open Patent Publication No. 2000-30642 discloses a road surface freezing prevention system and its construction method. The road surface frost prevention system includes an internal heating element and an external heating element with a built-in heating wire, an artificial intelligence sensor connected to these internal and external heating elements by connecting wires, and sensing the environment of the road and transmitting it to the central computer, and by the instructions of the central computer. It is composed of a central voltage regulator for automatically adjusting the heating wire.

Such a heating method takes a lot of installation and maintenance costs, and in particular has a drawback of high power consumption.

In addition, Japanese Patent Laid-Open No. 56-77405 discloses an apparatus for preventing road freezing using geothermal heat. The apparatus described in this publication embeds a heating pipe in which the upper end is disposed near the road surface. Moreover, the radiator fin which is wider than this heating pipe was connected to the lower end part of the heating pipe located in the ground. And, even in winter, the ground is maintained at a somewhat high temperature, but the heat in the ground is transferred to the road surface by a heating pipe, thereby preventing snow from accumulating on the road surface. However, the apparatus described in this publication requires a large number of radiator pins, and the overall structure is complicated and maintenance costs are high.

In addition, Japanese Patent Application Laid-Open No. 6-16700 discloses a heating pipe for preventing road freezing using antifreeze. This is to circulate the antifreeze by natural convection to collect geothermal heat to prevent freezing of the road surface, and has a complex structure consisting of a heat exchanger buried in the present, a heat storage tank or a heat pipe bent along the road surface. In addition, since the system itself needs to be assembled on site at the time of construction, a lot of work time is required and maintenance costs are increased.

The present invention for solving the above problems is to provide a heating pipe for preventing road ice freezing using a simple geometries, low construction and maintenance costs, economical geothermal.

The heating pipe for preventing road surface freezing using geothermal heat of the present invention for achieving the above object is a body which is buried vertically in the ground layer of the road and a hollow portion in which a heat transfer medium flows is formed, and a heat transfer medium heated through the hollow portion. Is provided with a heat dissipation unit is radiated heat is introduced, characterized in that consisting of a plurality of heat dissipation fins arranged horizontally below the pavement layer, such as concrete and asphalt.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the heating pipe for preventing road ice using geothermal heat according to a preferred embodiment of the present invention.

1 is a perspective view showing the configuration of the road surface anti-freezing heating pipe according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing the installation state of the road surface anti-freezing heating pipe shown in FIG.

First, as shown in Figure 1, in the preferred embodiment of the present invention as an example of the heating pipe for preventing the road surface freezing, a plurality of heat dissipation fins 16 are formed on the top of the 'b' shaped heating pipe 10 Is illustrated. The heating pipe 10 has a hollow portion formed therein, and the hollow portion is a vacuum tube type in which a heat transfer medium is contained. The heat transfer medium uses a liquid having a high thermal conductivity such as water or alcohol, and a gas such as ammonia or a refrigerant. Can also be used. On one side of each of the heat radiation fins 16, a plurality of projections 16a are formed to increase the heat radiation area.

Here, the radiating fins 16 have a structure in which a plurality of radiating fins 16 are disposed radially on the upper circumferential surface of the main body 12. By arranging the heat dissipation fins 16 in this way, the heat introduced from the main body 12 can be intensively dispersed in the heat of the heat exchange medium to the concrete or asphalt pavement layer 20 above.

2 is a view showing a state in which the heating pipe 10 according to the present invention is installed on the road, a plurality of heating pipe 10 is buried at a suitable interval on the road is expected to freeze. With reference to this will be described the process of freezing the road surface using the heating pipe 10 according to the present invention.

As shown here, the main body 12 constituting the heating pipe 10 is formed of a long cylindrical shape of the 'b' shape extending up and down, the hollow portion 14 containing a heat transfer medium therein Is formed. The hollow part 14 communicates with the heat radiating part 18 formed inside the heat radiating fin 16 of the upper portion, thereby enabling movement of the heat transfer medium. In the present embodiment, the plurality of heat dissipation fins 16 forming the upper portion of the heating pipe 10 is disposed at a position adjacent to the concrete or asphalt pavement layer 20. Although not shown, it is also possible to embed the heat radiation fin 16 in the concrete or asphalt pavement layer 20 according to the road conditions. In addition, the lower end of the heating pipe 10 is mainly buried in the ground it is preferable to make a cone shape of the pointed shape in order to facilitate the buried work.

In general, in the cold winter, even though the temperature of the atmosphere is low, the temperature of the strata 22 is always maintained at a certain level or higher. Therefore, the heat of the ground layer 22 is transferred to the lower part of the main body 12 which forms the heating pipe 10, so that the heat transfer medium contained in the hollow part 14 of the main body 12 is heated warmly. The heated heat transfer medium is raised by natural convection in the main body 12, as shown by the arrow P, and diffuses into the heat dissipation unit 18 formed on the upper part of the main body 12.

As such, the heat transferred to the heat dissipation unit 18 is transferred to the lower portion of the concrete or asphalt pavement layer 20 through the heat dissipation fins 16, thereby accumulating snow or water on the road surface above the pavement layer 20. Even if there is a freezing phenomenon is prevented.

On the other hand, the heat transfer medium that radiates heat from the heat dissipation unit 18 and descends along the arrow Q returns to the lower part of the main body 12. In this way, the convection inside the main body 12 continues, and the heat dissipation through the heat dissipation fin 16 is continuously performed, thereby allowing the paving layer 20 to be continuously heated, thereby preventing freezing of the road surface.

Next, Figure 3 is a cross-sectional view showing the installation state of the road surface anti-freezing heating pipe according to another embodiment of the present invention, in the present embodiment, the heat radiation fin (16 ') has a structure that extends vertically in succession have. As described above, the plurality of heat dissipation fins 16 ′ are continuously arranged at equal intervals vertically along the longitudinal direction of the main body 12, so that a wider area can be continuously heated.

The alternative structure and principle of operation are almost the same as described in FIG. That is, the heat of the ground layer 22 'is transferred to the lower part of the main body 12' which forms the heating pipe 10 ', so that the heat transfer medium contained in the hollow portion 14' of the main body 12 'is heated warmly. do. The heated heat transfer medium is raised by natural convection in the body 12 ', as shown by arrow P', and diffuses into the heat dissipating portion 18 'formed on the top of the body 12'.

As such, the heat transferred to the heat dissipation unit 18 'is transferred to the lower portion of the concrete or asphalt pavement layer 20' through the heat dissipation fins 16 'extending vertically at equal intervals, thereby paving the layer 20 ') This prevents freezing even if snow or water accumulates on the upper road surface.

Since the heating pipes 10 and 10 'of the present invention having such a configuration do not need to be used in combination with other complicated devices, the construction can be simply performed at low cost.

In the preferred embodiment of the present invention described so far, as a heating pipe for preventing frost on the road exemplified a circular heating pipe that is arranged radially with a plurality of heat dissipation fins at the top, but those skilled in the art It will be understood that various modifications, changes, additions, and the like can be made without departing from the spirit of the invention. For example, it is also possible to configure the heating pipe or the heat radiation fin into a polygonal shape such as a circle or a square to increase the heat transfer efficiency.

According to the present invention described above, the construction and the overall structure is simpler than the conventional apparatus, and the maintenance cost is low, and by providing a heating pipe for preventing the freezing of the road using geothermal heat, there is an advantage to promote the safe operation in winter.
