BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a melting device used for melting snow and preventing freezing of roofs, roads, etc. in cold regions.

2. Description of the Related Art A conventional device of this type is disclosed, for example, in Japanese Patent Publication No. 60-50276, and its outline is shown in FIG. In FIG. 4, reference numeral 1 denotes an evaporation section 1a and a plurality of condensation sections 1 extending from the evaporation section 1a to the section to be melted.
b, and a working fluid such as water or ammonia is sealed inside, and the evaporation part 1a of the heat transfer body 1 is
Working fluid is stored within. Further, a plurality of condensing portions 1b of the heat transfer body 1 are arranged at intervals along the longitudinal direction of the evaporation portion 1a of the heat transfer body 1, and are located above the evaporation portion 1a. Reference numeral 2 denotes a hot water pipe that passes through the evaporation section 1a of the heat transfer body 1 in its longitudinal direction and is immersed in the working fluid of the evaporation section 1a, through which hot water flows.

Next, the operation will be explained. When hot water is passed through the hot water pipe 2, the working fluid inside the evaporation section 1a of the heat transfer body 1 is heated and vaporized, and the amount of heat from the hot water is taken away as latent heat of evaporation and heat is transferred through the heat transfer body 1. condensation part 1 of body 1
Move to b. The vapor of the working fluid that has moved to the condensing section 1b of the heat transfer body 1 is cooled by the snow or snow and ice that has accumulated in the condensing section 1b, condenses and liquefies, and releases the latent heat of condensation into the snow or snow and ice. The liquefied working fluid flows along the inner wall surface of the heat transfer body 1 and returns to the evaporation section 1a of the heat transfer body 1. By repeating the above operations naturally, the heat of the hot water is transferred from the evaporating section 1a of the heat transfer body 1 to the condensation section 1b of the heat transfer body 1, and the heat is transferred to the vicinity of the condensation section 1b of the heat transfer body 1. Accumulated snow and ice will be melted.

[0004] However, in this conventional example, the melting process for snow and snow ice is performed only by releasing the latent heat of condensation from the condensing portion 1b of the heat transfer body 1, and the ability to melt the snow and snow ice is extremely low. Furthermore, since the condensing portions 1b of the heat transfer body 1 are arranged at intervals, the ability to melt snow and ice becomes even lower.

FIGS. 5 and 6 show improved versions of this.
The following are possible. A flat heat transfer plate 3 on which snow or snow and ice accumulates is arranged above the condensation part 1b of the heat transfer body 1, and the condensation part 1b of the heat transfer body 1 and the heat transfer plate 3 are integrated by, for example, welding. It is bonded and fixed to. In this case, snow and snow and ice accumulate on the flat heat transfer plate 3. Therefore, the amount of heat of the hot water flowing through the hot water pipe 2 is transferred from the evaporating section 1a of the heat transfer body 1 to the condensation section 1b of the heat transfer body 1, and is further transferred to the condensation section 1b of the heat transfer body 1.
The heat is transported from the condensation part 1b to the heat exchanger plate 3, and the snow and snow and ice accumulated on the heat exchanger plate 3 are melted through the heat exchanger plate 3. Compared to the conventional example shown in FIG. The melting processing capacity can be improved.

[0006]

However, in the conventional device described above, only a part of the tube wall of the condensing section 1b of the heat transfer body 1 is joined to the heat transfer plate 3. The heat conduction efficiency from 1b to the heat exchanger plate 3 is extremely poor, and there is a problem that the heat of the hot water is exhausted without being effectively used for melting snow and ice.

The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a melting apparatus that can efficiently melt snow and snow and ice.

[0008]

[Means for Solving the Problems] A melting processing apparatus according to the present invention includes a header in which a working fluid is sealed and constitutes an evaporation section, and a header that is provided through the header in the longitudinal direction and in which hot water is provided. A circulating hot water pipe, a plurality of angular pipe bodies that extend into the melting processing section apart from the header and have holes formed therein to form a condensation section, on which snow and snow and ice accumulate, and A conductor tube is provided which communicates with the hole of each square tube body.

[0009]

[Function] In the melting treatment apparatus of the present invention, the inside of the header through which the hot water pipe is penetrated is communicated with the hole of each square tube constituting the condensing section through the conduit pipe, so that the amount of heat of the hot water is transferred from the header to the conduit pipe. Heat is transported through the square tube to the square tube, and the snow and ice that accumulates on the square tube is directly melted.

[Example] Example 1. Embodiment 1 A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In each of these figures, 4 is a header in which a working fluid is sealed and constitutes an evaporation section, 5 is a hot water pipe that is provided to penetrate through the header 4 in the longitudinal direction and through which hot water flows, and 6 is a header 4. A plurality of angular tube bodies 7 are formed in the header 4 and in each angular tube body 6 to form a condensation section with holes 6a extending in the melting process area at a distance from the header 4 and on which snow and ice accumulate. These are conduction pipes that communicate with the holes 6a, and the respective communication portions are joined by brazing, for example. Further, the respective square tube bodies 6 are integrated with each other by, for example, brazing.

Next, the operation will be explained. When hot water is passed inside the hot water pipe 2, the working fluid inside the header 4 is heated and vaporized, and the heat of the hot water is taken away as latent heat of evaporation. It moves into the hole 6a of the body 6. The steam of the working fluid that has moved into the hole 6a of each square tube body 6 is condensed and liquefied because the temperature of the snow and ice that accumulates on each square tube body 6 is lower than that of hot water, and the latent heat of condensation is transferred to each square tube body 6. It is released from the pipe body 6 onto the snow and ice that accumulates thereon and melts it. The condensed and liquefied working fluid flows through the holes 6 of each square tube body 6.
The water flows back into the header 4 along the inner wall surface of a, passing through each of the conductive pipes 7. By naturally repeating the above operations, the heat of the hot water is transported from the header 4 through each conductive pipe 7 to each square tube body 6, and is deposited on the upper surface of each square tube body 6. It is possible to efficiently and effectively melt snow and snow and ice that has been melted evenly.

Example 2. In the above-described first embodiment, the case where the hole 6a of the square tube body 6 is circular is described, but the hole 6a may be a square shape similar to the square tube body 6, and the same as in the first embodiment. It has the effect of

Example 3. Furthermore, in the above-described first embodiment, a case has been described in which the respective square tube bodies 6 are integrated together by brazing, for example.
Of course, they may be integrated by soldering, welding, or joining with adhesive.

Example 4. Incidentally, in each of the above embodiments, a case has been described in which the respective angular tube bodies are integrated with each other, but they do not necessarily have to be integrated, and the intended purpose can also be achieved in this case.

[0015]

[Effects of the Invention] As explained above, the present invention communicates the inside of the header through which the hot water pipe has passed with the hole of each square tube constituting the condensing part through the conduit pipe, so that the amount of heat of the hot water is transferred from the header. This is a melting process that can efficiently melt snow and snow and ice, as heat is transported to the square tube through the conduction pipe, and the snow and snow and ice that accumulates on the square tube are directly melted. You can get the equipment.
