Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a snow melting device for a roof that incorporates a heat pipe and melts snow by installing a snow melting panel on the roof surface.

PRIOR ART Snow accumulation on roofs in cold regions can cause houses to collapse, so after a certain amount of snow has fallen, it is necessary to remove the snow, which poses a heavy financial and physical burden. For this reason, there has been a desire for devices that can easily and automatically remove snow from roofs, such as electric snow melting devices that use planar heating elements, and roofs that have a two-layered structure (upper and lower) and hot water in the space. Hot water circulation type snow melting equipment has been proposed. However, electric snow melting equipment has drawbacks in terms of durability and energy cost, and hot water circulation snow melting equipment requires fundamental changes to the structure of the roof, and the hot water temperature is uneven, making it difficult to melt snow uniformly. There were problems such as not being able to do it.

Therefore, the present applicant has already proposed a snow melting panel that can be installed on an existing roof and can melt snow uniformly (Japanese Patent Application No. 122774/1983;
(See No. 280462). In this method, a heat pipe and a heat insulating material are sandwiched between steel plates with the heat insulating material on the bottom side to form a plate shape, and one end of the heat pipe is connected to a high temperature fluid pipe to heat the snow through the heat pipe. It is designed to convey the following. According to this snow melting panel, heat can be applied to the snow accumulated on it via a heat pipe, and the heat can be supplied by, for example, flowing hot water as residual heat from a bath through a high-temperature fluid pipe. , it is possible to easily and easily melt snow from a roof.

Problems to be Solved by the Invention The snow melting panel described above generates a large amount of snow melt water in order to melt the snow that is in contact with its upper surface. Most of this snowmelt water flows toward the eaves, but since the high-temperature fluid pipe is installed at the eaves to provide bottom heat to the heat pipe, the snowmelt water receives heat from the high-temperature fluid pipe at the eaves, causing This prevents icicles from forming on the eaves due to melting snow.
However, when the above-mentioned conventional snow melting panels are placed on a roof with a gable structure, snowmelt water may also flow down to the gable side, and not only is it impossible to apply heat to the snowmelt water on the gable side. On the other hand, the snowmelt water was cooled by the outside air, resulting in the formation and growth of icicles on the gable side.

This invention was made against the background of the above-mentioned circumstances, and aims to provide a snow melting device for a roof that can suppress the formation of icicles on the gable side.

Means for Solving the Problems In order to achieve the above-mentioned purpose, this invention consists of a plurality of snow melting panels formed into a flat plate by sandwiching heat pipes with one end facing a high temperature source between plate materials. In a roof snow melting device in which the heat pipe is arranged on the roof surface along the slope direction of the roof, the heat from the heat pipe is transferred to the snow melting panel arranged on one side in the horizontal direction of the roof surface. A heat transfer plate that transmits heat is installed so that it hangs down from the gable side edge of the roof. Specifically, the snow melting panel is placed on one side of the roof surface in the horizontal direction, and the snow melting panel is in close contact with a portion corresponding to the heat pipe and extends laterally from the heat pipe corresponding portion. A heat exchanger plate extending downward from the side edge of the roof is characterized in that the heat exchanger plate is attached so that the extending portion thereof hangs down from the side edge on the gable side of the roof.

Function In this design, the heat for snow melting is applied to one end of the heat pipe, and the heat is carried along the length of the heat pipe to melt the snow. The resulting snowmelt water mainly flows along the slope, but snowmelt water that flows toward the side edges due to the presence of obstacles or a large amount of water flows down from the gable side. In that case, the snowmelt water that flows down from the gable side flows down the heat exchanger plate that hangs down from the side edge, so it receives heat at that time, and the snowmelt water freezes and becomes icicles. There is no.

Embodiment Next, an embodiment of this invention will be described with reference to the drawings.

The apparatus shown in FIG. 1 and FIG.
It uses the snow melting panel 1 proposed in
The snow melting panel 1 has a flat plate shape as a whole by arranging heat pipes 3 above the heat insulating material 2 and sandwiching them between steel materials 4, and furthermore, ridges 5 serving as legs are provided on the bottom side of the heat pipes. The heat pipe 3 is formed along the longitudinal direction, and one end of the heat pipe 3 is connected to a high temperature fluid pipe 6 through which a high temperature fluid serving as a heat source such as hot water flows. This snow melting panel 1
In general, a heat pipe 3 is installed between tile rods 7 on a roof covered with steel plates or copper plates so that the heat pipe 3 is along the inclination direction and the high-temperature fluid pipe 6 is on the lower side. A heat transfer plate 8 is closely attached to the upper surface of the snow melting panel 1 disposed on the gable side so as to straddle the heat pipes 3. It is arranged in a state where it hangs down from the side edge parallel to the side edge 3 along the side edge 9 on the gable side of the roof. That is, the heat transfer plate 8 is configured to be in close contact with a portion of the snow melting panel 1 corresponding to the upper surface of the heat pipe 3, extend laterally from that portion, and further extend downward from the side edge of the snow melting panel 1. has been done. A portion of the heat transfer plate 8 extending from the side edge of the snow melting panel 1 is arranged so as to hang down along the side edge 9 on the gable side of the roof. Note that as the heat transfer plate 8, a plate material having good thermal conductivity such as copper or aluminum may be used.

Snow melting using the above device is carried out by flowing a high temperature fluid such as hot water through the high temperature fluid pipe 6. In other words, if, for example, hot water is flowed into the high-temperature fluid pipe 6 under snowy conditions, the temperature of the end of the heat pipe 3 on the high-temperature fluid pipe 6 side will become high, and the temperature of the end on the opposite side will become low. From there, the heat pipe 3 transports heat in its longitudinal direction, that is, throughout the snow melting panel 1, and as a result, the snow on the snow melting panel 1 is melted. As described above, the snowmelt water generated by melting snow flows along the slope of the upper surface of the snow melting panel 1 towards the eaves, but in the snow melting panel 1 on the gable side, the snowmelt water does not flow down to the gable side. be. In that case, since the heat exchanger plate 8 is provided hanging down on the gable side, the snowmelt water flows along the heat exchanger plate 8. This heat transfer plate 8 is in close contact with the top surface of the snow melting panel 1 so as to straddle the heat pipe 3, and receives heat from the heat pipe 3, increasing its temperature. Therefore, melted snow water does not freeze when it falls from the gable side of the roof. In other words, snowmelt water does not turn into icicles.

Effects of the invention As explained above, according to the snow melting device of this invention, a heat transfer plate that transmits heat from the heat pipe of the snow melting panel is provided on the gable side of the roof, so water flowing down to the gable side as snow melts is transferred. It is heated by the heat of the heat pipe via the hot plate, and therefore the melted snow water does not freeze when it falls from the roof, and it is possible to reliably prevent the formation of icicles on the gable side.
