Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to I! The present invention relates to a snow roof, and particularly to a snow melting roof that melts snow by applying heat through a heat pipe.

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. In order to eliminate these inconveniences, various efforts have been made to date.
An example of an effective system is one that uses well water or hot water. This rice plant has a structure in which a water pipe is installed at the top of the tilt machine, and hot water obtained from well water or a solar collector is sprayed from the pipe onto the top of the roof to melt snow.

Conventionally, attempts have been made to melt snow on roads by burying heat pipes near the road surface and using the heat pipes to transport geothermal heat close to the road surface. Since it has the advantage that it does not require additional water, it could be used for melting snow on the roofs of houses.

Problems to be Solved by the Invention However, with conventional equipment equipped with water sprinkler pipes, maintenance and management are troublesome as there is a risk of water leakage or blockage of the water spout due to debris, etc. In addition to water! ! ! Because the water sprayed for snow becomes wastewater, the amount of water discharged increases significantly, and water used for melting snow is also wasted.

There were problems such as high running costs and the need to find other suitable water sources in areas where pumping of water from wells is regulated.

On the other hand, using a heat pipe transfers heat directly to the snow to melt the snow, which has the advantage of low running costs, but unlike roads, snow melting on roofs needs to be considered for general households. Therefore, special consideration is required in terms of equipment cost, appearance, etc., and in the past, sufficient research has not been made into these matters.

In view of the above circumstances, this hair growth is low and has excellent external appearance.
Furthermore, it is an object of the present invention to provide an R snow roof structure with good workability.

Means for Solving the Problems In order to achieve the above object, the present invention arranges flexible heat pipes with corrugated pipes as containers in a meandering manner on the roof surface between the tile rods, and The heat pipe is covered with a metal presser plate having a width that is approximately the same as the spacing between the tile rods, and one end of the heat pipe is attached in the axial direction to a header pipe for a% hot fluid arranged along the lower edge of the roof. It is characterized by being inserted along the line.

Function Therefore, according to the structure of the snow melting roof of the present invention, the end of the heat pipe inserted into the header pipe becomes the heating part, and the meandering part arranged along the roof surface becomes the heat radiation part. Therefore, the snow accumulated on l1ffl is melted by the heat carried from the hot fluid in the header tube by the heat pipe. In this case, since the heat pipes are arranged in a meandering manner and the full-gate tube is used as a container, the heat dissipation area becomes larger, and the number of heat pipes required can therefore be reduced. In addition, in this invention, the holding plate protects the heat pipe and improves the overall appearance of the roof, and in addition, the holding plate forms a flat surface, which helps snow fall.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of the partial element Is of an example in which this invention is applied to a tiled roof using metal plates such as colored iron plates.
Further, FIG. 2 is a view taken along the IF-'ff line in FIG.
A heat pipe 1 is arranged in a meandering manner on the root surface between the tile rods 2, and one end thereof is inserted along its axial direction into a header pipe 3 arranged horizontally at the lower edge of the roof, that is, at the eaves. ing.

Heat pipe 1 is a full gate tube (wavy tube) connected to a container (
It is flexible and can be laid in a meandering manner according to the pitch of the tile rods 2 at the construction site, making it easy to install and reducing the required heat dissipation area between the tiles 82. It is secured with one heat pipe. The meandering part along the open surface of the heat pipe 1 is covered by a holding plate 4, which protects the heat pipe 1 and improves its appearance. It is formed by a plate as a cover with almost the same height as the tile rod 2, and its both sides are bent into a V shape as shown in Fig. 2, and the cover is fitted between the tiles 12 by the elastic force of the bent portion 5 fixed in state. In addition,
Since both sides of the presser plate 4 are elastically deformable, the width of the presser plate 4 is variable, so that so-called □current bending is possible, which facilitates manufacturing and construction using the presser plate 4. becomes easier.

Further, the header pipe 3 is used to supply heat to one end of the heat pipe 1 by flowing a high-temperature fluid such as hot water as a heat source, and in the example shown in FIG. Therefore, the heat receiving area of the heat pipe 1 is increased relative to its length, and in other words, the header pipe 3 is made as short as possible.

Therefore, in the above-mentioned IPI structure, if high-temperature fluid such as hot water is allowed to flow through the header pipe 3 during the snowy season, the heat pipe 1
The end portion inserted into the header tube 3 serves as a heating portion, and the portion in contact with the snow via the presser plate 4 serves as a heat radiating portion to transport heat. As a result, the presser plate 4
The snow on the top will melt and be removed, or as the snow on the bottom melts, it will slide under its own weight and be removed. The snowmelt water generated in this way is discharged into rivers and sewers like normal rainwater, but although the high-temperature fluid that is the heat source gives heat to the snow and lowers its temperature, it can be collected via a designated piping route. Since there is no consumption of fluid used as a heat source such as hot water, running costs are low.

Effects of the Invention As is clear from the above explanation, in this invention, the heat pipes are arranged in a meandering manner on the roof surface, so a single heat pipe can cover a wide area, in other words, the number of beat pipes is small. Since the heat pipe is flexible and uses a full-gate pipe as a container, it is possible to install it in a meandering manner, making it possible to reduce costs. becomes good. Furthermore, since the heat pipe is covered by the holding plate, it is possible to protect the heat pipe and maintain the overall appearance of the roof.In addition, the flatness of the holding plate prevents snow from sliding and falling.・Can encourage removal. Furthermore, in this invention, one end of the heat pipe, which is the heating part, is inserted into the header pipe for high-temperature fluid along its axial direction. A short header pipe is sufficient to secure the heat exchange area, and in this respect, the appearance of the roof or the house as a whole can be maintained in good condition.
