Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a hot water panel, which melts snow by circulating hot water by installing it on a roof, for example.
Or it relates to a hot water panel that can be used for a wide range of purposes such as heating.

(Prior Art) Conventionally, a snow melting device for melting snow accumulated on a roof involves circulating hot water in a hot water pipe, as described in, for example, Japanese Utility Model Application Publication No. 19369/1983.
The structure is such that the snow that accumulates on the roof is melted by heating the hot water pipes.

(Problems to be solved by the invention) However, the above-mentioned conventional hot water pipes use steel pipes, and these steel pipes are prone to adhesion of scales such as calcium, magnesium compounds, and silicates, and only the hot water pipe portion It has the problem of being easily melted and requiring a high piping density.

Therefore, it is possible to use copper pipes as hot water pipes, which are less likely to attract scale, have high thermal conductivity, and are easy to work with. However, copper pipes are soft and have good electrical conductivity, so they are susceptible to electrolytic corrosion and have poor durability. It has inferior problems. Furthermore, in the method of melting snow by installing hot water pipes and forming a hot water circulation path in the hot water pipes, only the pipe portion melts, resulting in poor snow melting efficiency and the problem of having to increase the density of the pipes. There is.

This invention was devised in view of the above problems, and has high thermal efficiency, high durability, and good workability.
The objective is to provide highly versatile hot water panels, such as snow melting panels and heating panels.

[Structure of the idea]

(Means for Solving the Problems) The hot water panel of the present invention has a copper pipe forming a hot water flow path covered with a sheet of glass fiber reinforced plastic from both sides, and at least one side of this sheet is shaped like a flat plate. It was formed in

(Function) The hot water panel of the present invention circulates hot water through a circulation path formed of copper pipes, heats the copper pipes, and conducts heat to the glass fiber reinforced plastic sheet that clamps and covers the copper pipes. The flat plate-shaped portion of this sheet is heated to a substantially uniform temperature to melt snow on the roof where the panel is installed, or to heat the room.

(Example) Hereinafter, an example of the hot water panel of the present invention will be described with reference to the drawings.

1 is a hot water panel body, and this hot water panel body 1 is composed of a copper pipe 2 and a pair of sheets 3 and 4.
A plurality of copper pipes 2 are connected in parallel between a hot water inlet 5 and a hot water outlet 6, and joints 7 and 8 are provided in the hot water inlet 5 and hot water outlet 6, respectively. In the flow path 9 formed by the copper tube 2, warm water heated by a boiler (not shown), such as water mixed with antifreeze, is circulated.

The sheets 3 and 4 are made of glass fiber reinforced plastic, and the copper tube 2 forming the flow path 9 is tightly covered between the sheets 3 and 4, and the lower sheet 4 is made of copper. The tube 2 is bulged in a substantially arc shape along the outer periphery to form a heat exchange surface, and the upper sheet 3 is formed in a flat shape.

When this hot water panel is used as a snow melting device for a roof, as shown in FIG. It is attached between the straw bars 15 provided on the heat insulating material 13 via the stoppers 14.

Further, the arc-shaped bulge portion 4a of the lower sheet 4 is brought into contact with the heat insulating material 13, and the bulge portion 4a of the lower sheet 4 is
A cavity 17 is formed in the gap between and the heat insulating material 13.

For example, a flap plate 16 is stretched over the upper surface of the upper sheet 3 to cover the hot water panel body 1.

Next, the operation of this embodiment will be explained.

First, hot water sent from a boiler or the like is introduced into the copper pipe 2 from the hot water introduction part 5 located on the eaves side of the copper pipe 2.
The hot water is led out through the flow path 9 to the hot water outlet section 6 on the ridge side and circulated to the boiler. At this time, the heat of the hot water is conducted from the copper pipe 2 to the dam plate 16 via the sheets 3 and 4, and heats the dam plate 16. The hot water introduction part 5 of the copper pipe 2 is located on the side of the eaves, and the hot water in this hot water introduction part 5 has a high temperature, and the high temperature air rises toward the ridge side along the sheet 4 on the lower side of the cavity 17. Heating is performed via the sheets 3 and 4, and the plate 16
Warm up.

According to the above embodiment, the copper tube 2 is tightly covered with the sheets 3 and 4, and at least one surface is made flat, so that a heating element close to the surface can be obtained, and the electric contact of the copper tube 2 can be made flat. It is possible to prevent deterioration due to corrosion and improve durability.

Furthermore, by disposing the copper pipe 2 along the slope of the roof, a cavity 17 is formed in the bulging part 4a of the sheet 4, and heated air flows through this cavity 17 from the bottom to the top through thermal convection. Snow melts efficiently because it rises due to

Furthermore, if a non-flammable board such as a mat is placed on the top surface of the hot water panel body 1 to form an exposed type hot water panel body 1, durability can be increased. In addition, it can be applied not only to roofs made of flat boards but also to straw roofs.

Furthermore, the hot water panel body 1 is not limited to the method of attaching it to the upper surface of the shedding board 12 via the heat insulating material 13 as shown in the above embodiment, but the hot water panel body 1 can also be installed on an existing roof.

Further, when used as a snow melting panel for a steel frame or RC structure building, the hot water panel body 1 is laid flat on a flat roof to serve as a waterproof layer if necessary.

In addition, when this hot water panel is used as a floor heating device, for example, a heat insulating material is attached to the upper side of the joist rafters of the floor base via the floorboard with the flat sheet 3 of the hot water panel body 1 facing upward. Attach between the stoppers provided above. Then, a surface material such as a carpet is stretched over the upper surface of the upper sheet 3 via a base plate.

By using the hot water panel of the above example on the floor surface, the thickness of the hot water panel body 1 is about 17 mm, which is thinner than a conventional floor heating panel, so construction is easy for the floor surface of a wooden building. Moreover, even if it is installed on an existing floor surface, problems with height are unlikely to occur.

Further, when this hot water panel is used as a wall heating device, the planar sheet of the hot water panel body 1 is placed on the indoor side, and the panel is attached from the wall surface through the cavity, and the surface material is attached to the sheet 3.

By circulating hot water in the copper pipe 2 from the floor side to the ceiling side, the floor side has high temperature hot water and the ceiling side has relatively low temperature hot water, so air convection occurs in the cavity. The entire room can be heated using convection air and radiant heat from the walls.

Further, for example, hot water can be maintained by disposing the hot water panel body 1 on the bottom or side wall of a water storage such as a fish farm.

Since no electricity is used, there is no risk of electrical leakage, and since the hot water panel body 1 is formed of the copper pipes 2 and the sheets 3 and 4 of glass fiber reinforced plastic, there is no risk of electrolytic corrosion of the copper pipes 2. There is no.

[Effect of idea]

According to the present invention, a glass fiber-reinforced plastic sheet is closely attached to a copper tube and covered with a clamp, and at least one surface is made flat, so a heating element close to the surface can be obtained, and deterioration due to electric contact can be prevented, which can be efficiently scaled. Even if copper pipes are used, which have less adhesion and are easy to install, they are electrically insulated with glass fiber-reinforced plastic sheets, eliminating the risk of electrical contact and improving durability.
