Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat generating panel that is used as a roof base material or as a direct N rooting material and exhibits a high level of snow melting ability.

[Conventional technology]

Conventional roofs intended for snow melting, whether panels or non-panels, have heating elements 6, such as hot water pipes, arranged at regular intervals directly under the roofing material 14, as shown in Fig. 5, and around them. It is filled with insulation material lO. 11 is a field board, and 11' is a rafter.

(Problem to be solved by the invention) In this case, the snow melts well near the heating element 6, but the snow melts well near the heating element 6.
The snow melting effect is reduced in the middle part of the heating element 6, and a cavity 13 is formed in the roof snow 12 directly above the heating element 6. When a cavity is formed, the air inside acts as an insulator, making it even more difficult for the surrounding lightning 12 to melt, resulting in a problem that the snow melting effect on the roof is significantly degraded.

The present invention aims to solve this problem and provide a heat generating panel that can melt roof snow uniformly and powerfully.

[Means for solving problems]

The features of the heat generating panel of the present invention will be described based on the embodiment shown in FIG. It is divided into multiple directions.

In each space, a heating element 6 is arranged in the longitudinal direction with a gap around the periphery.

[For production]

If such a heat generating panel is used as a roof base material or directly as a roof material and the heat generating element 6 is made to generate heat, the heat generating element 6
The convection generated by the partition plate 5 that partitions the space inside the box l
Since the interference between convection currents is avoided,
The heat transfer effect by convection is promoted. As a result, each space is heated efficiently as a whole, and this heat is dissipated upward through the heat transfer plate 2, resulting in a uniform temperature distribution on the roof surface and a strong, even snow melting effect. It will be done.

〔Example〕

FIG. 1 is a plan view and a sectional view of a heat generating panel according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view showing details of an end portion, and FIG. 3 is a schematic diagram showing an example of installation.

In FIG. 1, the L-shaped deck plate constituting the box l has its open surface facing upward, and a heat exchanger plate 2 is fixed to the upper surface, and an internal space is formed by ribs as a partition plate 5 to form a plurality of internal spaces in the width direction. It is divided into two parts.

In addition to using an L-shaped deck plate as in the embodiment, this box l may be made by welding iron plates as shown in FIG. The C-shaped steel 4 may be fixed in parallel on top of the plate, or it may be made of a non-ferrous metal such as aluminum or a synthetic resin. However, the heat transfer plate 2 may be made of a material with good thermal conductivity Therefore, metals, especially aluminum and stainless steel, are recommended over synthetic resins.

Alternatively, the heat transfer plate 2 may be a heat generating panel to which a roofing material with good thermal conductivity is directly attached.

Note that, as shown in FIG. 4(b), if a heat insulating material 1O is provided on the lower surface of the heat generating panel, the snow melting effect will be further improved.

Heating elements 6 arranged longitudinally within individual spaces of the box body 1
is a hot water pipe, which is fixed to the heat exchanger plate 2 by one vertical fin 7 which also serves as a heat exchanger plate, and is supported in the space.

In addition to a hot water pipe, the heating element 6 may be a heating medium supply pipe such as a heating gas pipe, an electric heating element such as an electric heater or a ceramic heater, or a heat pipe, and the heating elements 6 may be provided in multiple rows within the space. is also possible.

The heating element 6 is supported by the fins 7 as shown in the illustrated example.
The fins 7 not only serve as a heat transfer plate but also have a rectifying effect like the partition plate 5, thereby further improving the convection and rectifying effects in the space. The number of fins 7 may be one as shown in the illustrated example, but they may also be arranged one each on the top and bottom, or they may be combined in a large shape as shown in FIG. 4 (b). For example, the fins 7 further promote convection within the space.

81 and 8! are injection pipes and discharge pipes for hot water, etc. connected to the heating element 6 at both longitudinal ends of the box l, and supply hot water etc. from the injection pipe 8I to each heating element 6゜6... in the box l. and each heating element 6,600. The hot water and the like that have exchanged heat with the surrounding space etc. are discharged to the outside of the box l through a discharge pipe 8t.

When multiple boxes L are arranged in parallel, the injection pipe 8. and the injection pipe 81 and the discharge pipe 83 of the panel where the drain pipe 88 is adjacent.
connected to.

As shown in FIG. 3, the injection tube 8. If hot water or the like is passed through the panel, the heat will heat the interior space of the panel.

In that case, each space partitioned by the partition plate 5 is heated independently, and there is no interference of convection between adjacent spaces.
Convection is promoted to heat the space efficiently and evenly, and this heat is radiated upward through the heat exchanger plate 2 on the top surface. According to the test results, the heating panel with the structure shown in Figure 1 has a temperature of 50℃.
16 hot water! / minute, when there is only one fin 7, the temperature variation on the two sides of the heat transfer plate is at most 3°C, which eliminates uneven snow melting and effectively prevents the formation of cavities in roof snow. Prevented.

In addition, according to the vertical fins 7 combined in the "large shape" shown in FIG. As a result, an excellent snow melting effect can be obtained, and the heating element 6 can be supported more reliably.

In addition, in the summer, the injection tube 8. Alternatively, if water is passed into the panel from the discharge pipe 8□, the temperature of the space inside the panel heated by solar energy is transmitted to the water passing through the heating element 6, and the discharge pipe 8! Alternatively, hot water for hot water supply can be obtained from the injection pipe 8I.

〔Effect of the invention〕

As is clear from the above explanation, the heat generating panel of the present invention heats the space inside the panel and heats the top surface as uniformly as possible, and at the same time, divides the space inside the panel into a plurality of areas to generate heat throughout the panel. This increases the efficiency and significantly increases the efficiency of melting roof snow as a whole. Furthermore, the corner plates for partitioning the space inside the panel increase the strength of the panel, making the panel suitable for use as a roofing material or a roof base material.

Further, as described in the embodiment, it can be used not only for snow melting but also for hot water supply, and can be said to be a panel with extremely high utility and practical value as a uniform heat radiator.
