In FIG. 2, 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.

Working fluid is stored inside. 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.

や雪氷の融解処理が行われる。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.

低いものとなる。[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.

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 condensing 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.

度か低いなどの問題がある。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 efficiency of heat conduction from the heat transfer plate 1b to the heat transfer plate 3 is poor, and the temperature distribution of the heat transfer plate 3 has problems such that the temperature is low in the portion of the heat transfer body 1 between the condensing portions 1b.

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 steam of the working fluid that has moved to the condensing section 1b of the heat transfer body 1 is condensed and liquefied because the temperature of the heat transfer plate 3 and the heat transfer layer 4 is lower than that of the hot water, and the latent heat of condensation is transferred from the condensation section 1b of the heat transfer body 1. The heat is released and transported to the heat transfer plate 3 through the heat transfer layer 4. The heat transfer plate 3 and the heat transfer layer 4 are heated by this condensed latent heat, and their temperature increases. The condensed and liquefied working fluid flows along the inner wall surface of the condensing section 1b of the heat transfer body 1 and flows back into 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 condensing section 1b of the heat transfer body 1, and further from the condensing section 1b of the heat transfer body 1. Heat is transported to the heat transfer plate 3 and the heat transfer layer 4. At this time, the entire heat transfer plate 3 is heated uniformly by the heat transfer layer 4 having good thermal conductivity, so that snow and snow and ice accumulated on the upper surfaces of the heat transfer plate 3 and the heat transfer layer 4 can be efficiently melted. Moreover, it can be carried out effectively and uniformly.
