The snowfall in the snowy areas of Japan (mainly on the Sea of Japan side) is
Due to the nature of snow, it has a high density, and depending on the outside temperature near the ground surface, it may turn into snow or sleet, and the density of snowfall is 0.3 t/m 3 ~
It reaches as much as 0.5t/ m3 . As a result, many houses are damaged, and people have to find some way to move the snow. These operations are often done manually, but they may be impossible depending on conditions such as climate and location, and are also dangerous. For this reason, hot water panel snow melting, electric heater snow melting, etc. are beginning to be used, but these types of snow melting conventionally have a surface structure with high emissivity in the infrared region, such as a black surface, or was not being used. However, with such a conventional snow melting surface, when the snow is partially melted during snow melting (for example, due to the quality of the snow or the position of the snow melting surface), the surface is covered with snow. In the areas where it is not used, thermal energy does not contribute to snow melting, but instead begins to radiate toward the sky, resulting in large heat losses and extremely low snow melting efficiency.

A heating means is disposed between the snow melting surface and the snow melting surface, which has a low emissivity in the infrared region.

次に、本実施例の作用について説明する。 Next, the operation of this embodiment will be explained.

パネル板は、放射率が低いため、雪がなく、空気

られ、その反面、放熱しなかつた分の熱が熱伝導
され、積雪を融解することになる。 First, when snow is accumulated on a snow melting panel and snow is melted, the entire surface of the panel is covered with snow at the beginning of the snow melting, so the entire surface of the panel is in contact with snow or a mixture of snow and water. In such a case, there is no difference in the snow melting effect between the snow melting panel of this embodiment and the conventional one with a black surface coating, for example. However, the amount of snowfall varies depending on the location of the roof, etc.
There are often differences in the speed of snow melting due to the influence of the outside world and the nature of the snowpack (expressed by density, etc.). If the snow does not melt uniformly over the entire snow melting surface, as shown in Figure 1, the snow 5
However, even after some of the snow has melted, some snow remains. In such a case, in the case of a conventional snow melting surface, radiation is generated from the snow-free surface toward the outside world (sky), increasing heat loss due to radiation, whereas in this example, Since the surface of the snow melting panel has a low emissivity, there is very little heat radiation from this area where there is no snow.
Therefore, heat is conducted toward the snowpack, which has a large heat capacity and a large temperature difference, and heats the snowpack, contributing to snow melting. In other words, since the snow melting panel board of this example has a low emissivity, heat radiation from the surface that is free of snow and in contact with the air is suppressed, and on the other hand, the heat that is not radiated is transferred through thermal conduction. This will cause the snow to melt.
したがつて、本実施例によれば、融雪面の雪が
融けてしまつて外界と接すると、この面からの放
熱を抑えることができる。 Therefore, according to this embodiment, when the snow on the snow melting surface melts and comes into contact with the outside world, heat radiation from this surface can be suppressed.
また、本実施例によれば、放熱の抑えられた熱
が付近の積雪の融解に作用するため、熱損失の少
ない効率の良の融雪を行うことができる。 Furthermore, according to this embodiment, since the heat whose radiation is suppressed acts on the melting of snow in the vicinity, highly efficient snow melting with less heat loss can be achieved.
