Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a melting device used for melting snow and preventing freezing of roofs, roads, etc. in cold regions, for example.

[Conventional technology]

As a conventional device of this kind, for example, the Japanese Patent Publication No. 60-5027
There is one disclosed in Japanese Patent No. 6, and the one shown in FIG. 2 can be considered as an improved example of this. In Figure 2, (1
) has an evaporating section (la) and a plurality of condensing sections (lb) extending from the evaporating section (1a) to the heat transfer target section, and a working fluid such as water or ammonia is sealed inside. The working fluid is stored in the evaporation part (la) of the heat transfer body (1).

Further, the condensing part (1b) of the heat transfer body (1) is
) are arranged at intervals along the longitudinal direction of the evaporation section (la), and are located above the evaporation section (1a).

(2) is a hot water pipe that extends 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 evaporator (la) of the heat transfer body (1) is heated and vaporized, and the heat amount of the hot water is taken away as latent heat of vaporization, and the heat transfer body ( 1) to the condensing part (1b) of the heat transfer body (1). Condensation part of heat transfer body (1) (
The vapor of the working fluid that has moved to the condensation section (1b)
It is cooled by snow and ice that has accumulated nearby, condenses and liquefies, and releases the latent heat of condensation into the snow and snow water. The liquefied working fluid travels along the inner wall surface of the heat transfer body (1) and returns to the evaporation section (la) of the heat transfer body (1). By repeating the above operations naturally, the amount of heat in the hot water is transferred to the heat transfer body (
1) from the evaporating section (1a) of the heat transfer tube (1) to the condensing section (1) of the heat transfer tube (1).
The heat is transported to b), and the snow and snow and ice accumulated near the condensing part (lb) of the heat transfer body (1) are melted.

However, in this conventional example, the melting process for snow and snow ice is only by releasing the latent heat of condensation from the condensing part (1b) of the heat transfer body (1), and the ability to melt snow and snow ice is extremely low. Moreover, since the condensing parts (1b) of the heat transfer body (1) are arranged at intervals, the ability to melt snow and ice becomes even lower.

As an improved version of this, the ones shown in FIGS. 3 and 4 can be considered. A flat heat transfer plate (3) is placed above the condensation part (tb) of the heat transfer body (1), and the condensation part (lb) of the heat transfer body (1) and the heat transfer plate (3) are welded. They are integrally connected and fixed. In this case, snow and snow and ice accumulate on the flat heat transfer plate (3). Therefore, the amount of heat possessed by the hot water flowing through the hot water pipe (2) is transferred from the evaporating part (la) of the heat transfer body (1) to the condensation part (1b) of the heat transfer body (1), and then further to the heat transfer body. The accumulated snow and snow ice is melted in step (1), and the ability to melt the snow and snow ice is improved compared to the conventional example shown in FIG.

[Problem to be solved by the invention]

However, in the conventional device described above, only a part of the tube wall of the condensing part (lb) of the heat transfer body (1) is joined to the heat exchanger plate (3). ) to the heat exchanger plate (3) is extremely poor, and there is a problem in that the heat of the hot water is exhausted without being effectively used for melting snow and ice. Furthermore, since the plurality of condensing parts (1b) of the heat transfer body (1) are joined to the heat transfer plate (3), there is a problem that the manufacturing cost is high.

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

[Means for Solving the Problems] A melting treatment apparatus according to the present invention has a housing groove bent into a semicircular shape for housing the condensing part of the heat transfer body, and the condensing part of the heat transfer body is placed in the housing groove. A pair of heat exchanger plates are provided to accommodate and sandwich the heat exchanger.

[Effect]

In the melting treatment apparatus according to the present invention, heat from the condensing portion of the heat transfer body is efficiently conducted from the peripheral wall of the M arm portion to the pair of heat transfer plates.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. In Fig. 1, (1) is a heat transfer tube, (1b) is a condensing section of the heat transfer tube (1), and (4a) and (4b> are condensing sections (1b) of a heat transfer body (1) on opposing surfaces. 〉Accommodation groove (
4C) and its accommodation! (4C) is a pair of heat transfer plates that accommodate and sandwich the condensation part (1b) of the heat transfer body (1). (not shown). In addition, if there is a gap between the heat transfer plates (4a), (4b) of the accommodation groove (4C) and the condensation part (1b) of the heat transfer body (1), or if you want to further increase the heat transfer efficiency, , 1m ('IC) heat exchanger plate (4a), (4b
) and the condensing part (1b) of the heat transfer body (1) may be loaded with a thermally conductive material such as heat transfer cement. Further, for example, a heat conductive tape or the like may be wrapped around the condensing portion (1b) of the heat transfer body (1). Further, although not shown, heat leakage from the heat exchanger plate (4b) can be prevented by arranging a heat insulating material on the lower surface side of the heat exchanger plate (4b).

Next, the operation will be explained. When hot water is passed through the hot water pipe (2), the working fluid inside the evaporation part (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 transfer (1 ) to the condensing part (1b) of the heat transfer body (1). Condensation part (l) of heat transfer body (1)
The steam of the working fluid that has moved to b) is transferred to a pair of heat exchanger plates (4a).
, (4b) is at a lower temperature than hot water, so it condenses and liquefies, and the latent heat of condensation is released from the entire surface of the peripheral wall of the condensing part (1b) of the heat transfer body (1) to the pair of heat exchanger plates (4a) and (4b). . This latent heat of condensation causes a pair of heat exchanger plates (4a),
(4b) is heated and its temperature increases. The liquefied working fluid is transmitted along the inner wall surface of the heat transfer body (1) and is transferred to the heat transfer body (1).
The mixture is refluxed to the evaporation section (1a) of 1). By repeating the above operations naturally, the heat of the hot water is transferred from the evaporating part (la) of the heat transfer body (1) to the condensation part (lb) of the heat transfer body (1), and further heat is transferred. A pair of heat exchanger plates (4a), (4b) from the condensing part (1b) of the transmitter (1)
Heat is efficiently and effectively transported throughout the heat exchanger plate (4a) through the pair of heat exchanger plates (4a) and (4b).
It is possible to efficiently and effectively melt the accumulated snow and snow and ice.

Furthermore, since the condensing part (1b) of the heat transfer body (1) is sandwiched between the pair of heat transfer plates (4a) and (4b) and integrally connected by bolts or the like, the conventional device described above is This is easier than fixing by welding, and manufacturing costs can be reduced.

〔Effect of the invention〕
