Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Industrial Field of Application This invention relates to a snow melting panel for melting snow accumulated on a roof, and particularly relates to a snow melting panel that is formed into a unit so as to be attached to the roof of an existing house. This relates to snow melting panels.

Conventional technology It is well known that large amounts of snowfall in cold regions have a major impact on social life. For example, snow on roofs can cause houses to collapse, so it is important to avoid snowfall exceeding a certain level. When this happens, it becomes necessary to remove snow, and the accompanying financial and physical burden increases. Conventionally, in order to solve this problem, electric snow melting equipment that melts snow by energizing a planar heating element installed on the roof to generate heat, and hot water pipes installed on the existing roof. A hot water circulation type snow melting device has been devised in which a new roof is constructed to cover the hot water pipes and the snow accumulated on the new roof is melted by the heat of the hot water flowing through the hot water pipes. It has also been considered to change the structure of the house itself without using any special equipment, to guide indoor heat to the backside of the roof through natural convection, and to melt snow using the so-called domestic waste heat.

Problems to be Solved by the Invention However, although it is easy to supply and control energy with electric snow melting equipment, there is a high risk of electrical leakage because it is placed directly in the natural environment, and it is difficult to use. The problem was that running costs were high because the unit cost of energy was high.

On the other hand, hot water circulation type snow melting equipment requires construction of an FR roof, which requires large-scale construction work and increases equipment costs.In addition, the temperature of the hot water is lowered due to heat being taken away by the snow. Since the temperature gradually decreases and the temperature becomes lower on the downstream side, the snow melting ability gradually decreases in the flow direction of the hot water, causing a problem in which uniform snow melting cannot be performed.

The above-mentioned method, which uses household waste heat, often has insufficient snow melting capacity, and the structure of the house is unique, so it is difficult to apply it to existing houses. However, there is a problem in that the equipment cost increases, and in particular, there is a problem in that it is not effective in melting snow at the eaves because heat cannot be supplied to the eaves.

The object of the present invention is to solve the above-mentioned problems and provide a snow melting panel that has excellent snow melting ability and can be easily attached to an existing roof without damaging its appearance.

Means for Solving the Problems In order to achieve the above object, the present invention attaches a heat pipe arranged substantially along the inclination direction of the roof surface to a board fixed to the roof surface, and The lower end of the installed state is connected to a high-temperature fluid pipe having a length equal to or less than the width of the plate material, and threaded portions for connection are formed at both ends of the high-temperature fluid pipe. It is characterized by:

Function: The snow melting panel of the present invention integrates a plate material fixed to the roof surface, a heat pipe, and a high-temperature fluid pipe that is a heating source for the heat pipe, and the heat pipe is arranged approximately in the direction of inclination of the roof surface. The high temperature fluid pipe is fixed on the roof surface along the roof so that the high temperature fluid pipe is located at the lower end thereof, and high temperature fluid such as hot water is flowed through the pipe connected to the high temperature fluid pipe. As a result, the part of the heat pipe that is in contact with the high-temperature fluid pipe becomes a heating part, and the part above it becomes a heat dissipation part, and the working fluid inside transports heat as latent heat, which melts snow. It will be done. This invention again! ! ! The snow layer can be set to any width, for example, by setting it to a width that is less than the spacing between the tile rods of a steel plate roof such as colored iron plates, it can be placed between the tile rods on the roof surface and the tile rods can be It can be fixed as a supporting member, and by doing so, it can be easily installed with a good appearance.

Example Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a plan view showing one embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view taken along the line ■-■ in FIG. 1, and as shown in these figures, the snow melting panel 1 is It has a structure in which a heat insulating material 2 and two heat pipes 3 are sandwiched and fixed between upper plate 4 and lower plate 5. That is, the heat insulating material 2 is a rectangular flat plate made of glass wool, expanded polystyrene, or the like, and two heat pipes 3 are arranged on the top surface thereof at a constant interval along the longitudinal direction. The upper plate 4 and the lower plate 5 are made of a metal plate such as a galvanized steel plate or a galvanized steel plate, and the upper plate 4 has a substantially semicircular cross section that wraps around and fixes the heat pipe 3. A protrusion 6 is formed. Further, a pair of protrusions 7 serving as supporting legs are formed on the lower plate 5 at substantially the same intervals as the intervals between the heat pipes 3 and along the longitudinal direction of the lower plate 5. And these upper plate 4 and lower plate 5 are
The heat insulating material 2 and the heat pipe 3 are sandwiched in close contact with each other, and the left and right edges of each are joined by a seam-folding process to be integrated. The edge-folded portion serves as a flange 8.

Furthermore, an end plate 9 having a U-shaped cross section is attached from the outside to one end in the longitudinal direction of the upper plate 4 and the lower plate 5 (the upper end in FIG. 1), while the other end ( An end plate 10 having a U-shaped cross section is inserted and attached to the lower end in FIG. Therefore, the heat insulating material 2 is sealed by the upper plate 4, the lower plate 5 and each end plate 9,10.

As is well known, the heat pipe 3 substantially encloses only a condensable fluid and is provided with a wick inside which generates capillary pressure, and the condensable fluid transports heat as its latent heat. One end of the heat pipe 3 protrudes toward one end in the longitudinal direction of the upper plate 4 and the lower plate 5 (lower side in FIG. 1), and is a high-temperature fluid pipe whose protruding end faces in the width direction of the plate material. 11. The connection structure is shown in FIG. 5 (A>). That is, the high-temperature fluid pipe 11 is for flowing high-temperature fluid such as hot water, and a jacket 12 having the same structure as the heat pipe 3 is provided on the outer periphery of the middle part. They are attached concentrically, and each heat pipe 3 is communicated with this jacket 12.The connection structure between the heat pipe 3 and the high-temperature fluid pipe 11 is shown in FIG. In addition to the structure, for example, as shown in FIG. 5(B), a structure in which the end of the heat pipe 3 is inserted and fixed inside the high-temperature fluid pipe 11 can also be adopted.

The spacing between the flanges 8, that is, the width of the snow melting panel 1, is set to be equal to or less than the spacing between the tile rods on the target roof, and the length of the high temperature fluid pipe 11 is set to less than that width, and the high temperature fluid ! ! Threaded portions 13 for connection are formed at both ends of 11.

Next, the function of the above-mentioned snow melting panel 1 will be explained together with how to use it. Figures 6 and 7 are schematic diagrams showing the installation on a steel plate roof, and as shown in these figures,
The snow melting panel 1 is installed between the tile rods 16 so that the high temperature fluid pipe 11 thereof is located near the eaves 14 and the heat pipe 3 substantially follows the inclination direction of the roof surface 15. In that case, the protrusion 7 formed on the lower plate 5! ! ! Since the panel 1 is supported, a gap C is formed between the roof surface 15 and the snow melting panel 1 (see FIG. 2). In this state, each snow melting panel 1 is fixed to the roof, and adjacent high temperature fluid pipes 11 are connected to each other. Various structures can be adopted as the fixing structure of the snow melting panel 1, examples of which are shown in FIGS. 8 and 9. 8th
The figure shows an example where the width of the flange 8 is sufficiently wide,
A connecting plate 17 having a concave cross section and having a length extending over the entire length of the tile rod 16 is fixed on the tile rod 16, and the side edge of the connecting plate 17 and the flange 8 of the snow melting panel 1 are folded. The structure is connected and integrated. With such a fixed structure, by adjusting the bending allowance of the flange 8, the substantial width of the snow melting panel 1 can be adjusted to easily match the spacing between the tile rods 17. The example shown in FIG. 9 is an example in which the width of the snow melting panel 1 almost matches the interval between the tile bars 16, and the middle part of the band-shaped fixing fitting 18 is fixed to the upper surface of the tile bar 16. At the same time, both ends of the fixing fittings 18 are fixed to the upper surface of the snow melting panel 1, and a plurality of such fixing fittings 18 are provided at regular intervals in the longitudinal direction of the tile rod 17.

The high-temperature fluid pipes 11 are interconnected by connecting both ends of a U-bent pipe 19 that straddles the tile rod 16 to the threaded portion 13 via an elbow 20, as shown in FIG.

With the installation as described above, when it snows, the high temperature fluid pipe 11
If a high-temperature fluid such as hot water, steam, or high-temperature exhaust gas is allowed to flow inside the heat pipe 3, the part of the heat pipe 3 that is in contact with the high-temperature fluid pipe 11 becomes a heating part, and the part sandwiched between the plates is cooled by snow. It becomes a heat dissipation part. In other words, the condensable fluid in the heat pipe 3 receives heat from the high vortex fluid in the heating section and evaporates, the vapor gives heat to the snow in the heat dissipation section and condenses, and the liquefied condensable fluid returns to the heating section. Reflux. Therefore, the heat possessed by the high-temperature fluid is carried by the heat pipe 3 and applied to the snow, and as a result, the snow is melted. In that case, the temperature of the entire heat pipe 3 is equalized due to its characteristics, so snow melting occurs uniformly in the axial direction of the heat pipe 3, and since the heat insulating material 2 is provided below the heat pipe 3, the temperature is uniform throughout the heat pipe 3. can be effectively used for snow melting. Furthermore, the snowmelt water flows through the upper surface of the upper plate 4 and the gap C between the snowmelt panel 1 and the roof surface 15, but since the gap C is formed sufficiently wide by the ridges 7, the snowmelt water and dirt can flow. It is possible to prevent the particles from accumulating in the gap C, thereby reducing damage such as corrosion to the roof surface 15.

Effects of the Invention As is clear from the above explanation, the snow melting panel of the present invention integrates a heat pipe that transports heat, a board fixed to cover the roof surface, and a high-temperature fluid pipe that transports heat to the heat pipe. Because it has a unitized structure, it can be easily and inexpensively installed on an existing roof without making major modifications.Furthermore, it can be made into almost the same form as the roof shingle, so it has a good appearance. can be kept. In particular, by making the width less than the interval between the tile rods, it can be accommodated between the tile rods, so the appearance of the house can be maintained as before. Also, by using a heat pipe, uniform snow melting becomes possible. Furthermore, by providing protrusions that serve as supporting legs, a gap can be created between the roof and the roof to improve ventilation, thereby preventing corrosion and dirt accumulation on the existing roof.
