2. Description of the Related Art Conventionally, a solar heat collecting method using solar heat has been proposed. For example, Japanese Patent No. 2649906
No. PR "Solar heat collector", Patent No. 2846913
A publicity bulletin “Method and Apparatus for Preheating Building Air” is known. The former is a heat collecting plate that collects heat on the roof without being affected by the solar altitude, but cannot cope with the solar azimuth. In the latter method, the heat collection panel is exposed to the outside world, a plurality of air intake holes are provided in the heat collection panel, and the heat collection panel is taken in behind the heat collection panel. An inlet is provided. In both cases, the heat collection temperature suddenly dropped due to the influence of wind and shade, and stable heat collection and a gradual temperature drop were not obtained.

[0003] However, in order to utilize solar heat with high efficiency all year round, there is no need to deal with the solar altitude and the solar azimuth without limiting the area. The roof or wall alone must be able to accommodate both the roof and the wall because the heat collection area is limited. Further, conventionally, since the heat collecting efficiency is poor, the cost tends to increase in order to increase the heat collecting area, and the cost must be reduced.

[0004]

The problem to be solved by the present invention is that solar radiation from the sun is efficiently collected throughout the year in a fixed state without being affected by the solar altitude and the solar azimuth,
It is an object of the present invention to provide an inexpensive solar heat collecting panel which can be used for the exterior of a building and a roof without enclosing the heat collecting panel in a case and which is hardly influenced by the shade and wind.

[0005]

SUMMARY OF THE INVENTION The present invention has been studied to solve the problems of the prior art, and in order to achieve the object, a flat and woven curved elongated metal plate having good thermal conductivity has been formed. An inexpensive and highly efficient heat collecting panel having a simple configuration and easy workability has been successfully obtained by using the heat collecting panel, as follows.

According to the first aspect of the present invention, there is provided a panel which collects solar heat without being affected by the time and season of solar radiation, wherein a metal plate for collecting heat having a good thermal conductivity is used.
The heat-collecting metal plate is plain-woven to make it a heat-collecting panel that can be used as a building exterior or roofing material, and the heat collected by the heat-collecting metal warms the surrounding air and is used for heat collection. A heat-collecting panel that can be used as an exterior or roofing material for buildings with the features of rising through the gaps in the metal, causing turbulence in the rising air, and the surface shape of the heat-collecting panel. And that the heat collection panel has an action of efficiently repeating heat collection, conduction, and radiation. According to the second aspect of the present invention, by receiving the solar radiation on a fixed horizontal, curved continuous surface with respect to the incident angle that varies depending on the season due to the solar altitude of the solar radiation, the solar radiation always has an appropriate angle with respect to the sunlight. Because it can collect heat more efficiently than a vertical plane, it has the feature that it can be installed without making an angle on the vertical plane regardless of the area. In addition, in order to receive the solar radiation with a fixed vertical, curved metal plate for the incident angle that changes depending on the time due to the solar azimuth of the solar radiation, the heat collection panel is installed facing the direction of the solar radiation. As a result, it is possible to have an appropriate angle with respect to the incident angle, and to obtain heat more efficiently than heat collection by a fixed vertical plane, so that heat is collected efficiently regardless of time. It has features that can do it. According to the third aspect of the present invention, each of the heat-collecting metal plates formed in a plain weave has a feature that it can be fixed and used as an exterior material of a building. According to the invention of claim 4, a gap is generated between the heat collecting metal plates by flat weaving the curved heat collecting metal plate, and heat flows from the higher side to the lower side. It has the feature that heated air moves and raises the surface of the heat collecting panel. According to the fifth aspect of the present invention, by forming irregularities on the surface of the heat collecting panel by forming a plain weave, turbulence is caused in the air to be raised around the panel, and the residence time of the air around the heat collecting panel is lengthened. It has the feature that heat can be efficiently transmitted to the surrounding air.

According to a sixth aspect of the present invention, the heat collecting panel has a feature of imitating a plain woven characteristic surface shape, and having functions as a heat collecting panel, a building exterior material and a roof material.

According to the invention of claim 7, air is stored at the place where the concave surface of the heat collecting metal plate overlaps with the concave surface of the heat collecting panel, and at the place where the convex surface overlaps with the convex surface, the heat collecting metal contacts each other to conduct heat. At the place where the concave surface and the convex surface overlap, the air that has been radiated from the heat collecting plate and heated is moved upward and to the left and right.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. The present invention uses curved horizontal and vertical metal plates for heat collection to increase the heat collection efficiency by plain weaving, and also responds to seasonal and time changes with the heat collection panel fixed, and achieves stable and high efficiency. It is a solar heat collection panel that can collect heat and has a dual effect as a heat collection panel and as exterior and roofing materials. FIG. 3 is a perspective view of the present invention. In the figure, the metal plates for heat collection in the horizontal direction are arranged alternately with concavities and convexities, and the metal plates for heat collection in the vertical direction are arranged alternately with concavities and convexities to form a plain weave. 1 and 2 are horizontal solar heat collecting metal plates,
Reference numerals 3 and 4 denote vertical solar heat collecting plates. Reference numeral 9 denotes a gap between the heat collecting metal plates which occurs at a minimum due to the property of plain weaving the metal. A, B, C, and D are overlapping patterns of the heat collecting metal plates that are generated when the heat collecting metal plates are plain-woven. FIG. 5 shows the shape formed in FIG. 3 with the horizontal heat collecting metal plates spaced apart so as to pass through a gentle curve to facilitate weaving of the vertical heat collecting metal plates. The gap 8 is larger than the gap 7 in FIG. FIG. 8 shows an overlapping state of the heat collecting metal. The metal plate for vertical heat collection receives sunlight and collects heat when it is exposed to the panel surface, and conducts heat collected on the front side when it is on the back surface,
Dissipates conducted heat. Similarly to the horizontal direction, the metal plate for heat collection in the horizontal direction also collects heat when exposed to the front, conducts the collected heat while entering the back surface, and radiates the conducted heat. Further, at the place where the heat collecting metal plate comes into contact, the heat collected on the front surface is conducted to the back surface, and the heat is repeatedly radiated on the back surface. As a result, heat collection, conduction, and heat dissipation can be performed efficiently.
In addition, the heat collecting metal plate that is double-layered in a plain weave has the effect of storing more heat than a single heat collecting plate. FIG. 6 and FIG. 8 show changes in the solar radiation depending on the solar radiation state and time during the summer solstice mid-south and the winter solstice mid-south, and illustrate how heat and air generated by the solar radiation move around the heat collecting panel. In FIG. 7, a heat storage material is fitted into the metal collecting metal overlapping pattern A generated in FIGS. 3 and 5 in order to cope with a rapid temperature change due to a change in solar radiation and a temperature change due to wind. The thermal panel also has a function of storing heat, and is designed to have a gradual temperature change. The heat collection panel efficiently collects heat, conducts
If radiation does not occur, heat cannot be obtained efficiently. Aluminum has the best heat collection result as a metal plate for heat collection.

FIG. 9, FIG. 10, FIG. 11, and FIG. 12 show a solar heat collecting panel having the surface shape and characteristics of the solar heat collecting panel shown in FIG. 2 and FIG. is there. Solar panels must be inexpensive, high-performance and suitable for mass production. The features that produce the high-efficiency heat collection effect shown in FIG. 3 and FIG. 5 are changed from the plain weave form to the seasonal and time-dependent form, assuming that the form is inexpensive and suitable for mass production. It is shown as a form changed to a heat collecting panel shape. The horizontal heat collecting metal plates 12 curved in FIG. 10 are arranged in one direction. The curved metal plate for heat collection in the vertical direction passes in one direction, and the shape of the gap formed between the metal plates for heat collection shown in FIGS. Open to the top. This is because the heat collected by the curved horizontal heat collecting metal plate dissipates heat because the heat flows from the higher side to the lower side. It is devised to move through the opening from the bottom to the lower temperature back surface. 9 and 1
The solar heat collecting panel indicated by 0 is a solar heat collecting panel capable of collecting heat efficiently throughout the year, and the solar heat collecting panel shown in FIGS. 11 and 12 can collect heat most efficiently in winter, and radiates and radiates heat. The heated air on the heat collection panel surface
In order to increase the temperature, the residence time is devised to be longer, and in the summer, the solar heat collecting panel shape is formed on the eaves on the curved surface so that the heat absorption efficiency is significantly reduced . FIG. 13 and FIG. 14 show an example in which a C channel 21 is attached to an outer wall of a building, and a solar heat collecting panel is attached to the attached C channel using tapping screws or bolts. Although the duct and the fan are not shown, a horizontal duct is arranged on the upper part of the solar heat collecting panel, and the suction fan is attached to the duct portion, so that the heat in the air space 22 caused by the solar heat collecting panel is generated. Air can be sent out into the building. Due to the rise of the heated air around the solar heat collecting panel and the solar heat collecting panel installed outside the building, the air inside the air space is produced outside and the air inside the air space is replaced by the outside air Thus, the walls of the building will not be heated. In summer, solar thermal panels will play the role of insulation. The shape of the solar panel shown in the cross-sectional view of FIG. 14 requires heat in winter,
In summer, when heat is not collected, the upper part 19 of the horizontal heat collecting shape is made to protrude so that most of the solar radiation in the middle and south of the summer is shadow 23, and it is shaped like an eave. The shape is designed so as to be orthogonal to the solar altitude during mid-south so that the amount of heat collected is maximized. Further, at the 19 points in FIG. 14, the shape is devised so that the ascending air causes convection and stays to be heated further.

[0011]

As described above, when the solar heat collecting panel of the present invention is installed on a vertical surface facing south or on a roof surface, it is possible to enhance the heat collecting effect regardless of the season and time. Because it does not require a special case for solar panels, it can be easily installed on buildings and structures to be installed. In addition, since the construction can be performed without breaking, the construction cost can be greatly reduced, and the double effect of obtaining thermal energy for heating can be obtained. In summer, when installed on an existing wall, it has an energy-saving effect that plays the role of heat insulation. In order to maximize the use of solar heat without using fossil fuels, it is necessary to efficiently use the most environmentally friendly, clean and environmentally friendly solar energy that does not emit carbon dioxide, which causes global warming. Will be possible.
