Description

[Detailed Description of the Invention] This invention relates to an improvement of a solar collector frame used when installing a solar collector.

Conventional frames for solar heat collectors of this type are generally constructed by combining steel materials into one shape, for example, and connecting the joints by screws or by welding.

In other words, the solar collector frame is made of pipe materials, H steel, ■ steel, etc., which are combined into a trapezoidal shape, and the solar collector is installed on the slope of this trapezoid, and the slope is inclined with respect to the horizontal plane. The angle is set to an angle value that optimizes heat collection depending on the application, such as heating, cooling, or hot water supply.

Therefore, the above-mentioned inclination angle, that is, the optimal inclination angle for heat collection depending on the application, is 20° to 40° for cooling, 45° to 65° for heating, and 30° for hot water supply in Japan. It is well known that the angle ranges from 50° to 50°.

Therefore, the slope at such an optimal slope angle for heat collection,
In other words, the solar collector is installed at an angle.

However, since the frame uses thick material such as an angle or a channel, it generally has a drawback that its overall weight is heavy.

In addition, since they are often assembled by welding, they have the drawback of not only increasing costs but also being susceptible to corrosion and fatigue, resulting in a lack of durability.

Furthermore, unless a special configuration is used, a single mount can -
The drawback was that only the angle of inclination could be taken.

The purpose of this invention was to eliminate the above-mentioned drawbacks, and to reduce weight, improve durability and reliability, and reduce cost. To provide a mount for a solar collector, which can obtain the optimum inclination angle for heat with a single unit.

In order to achieve this purpose, this invention forms a triangular shape with a plate of a predetermined width, and at least two of its interior angles are set at angles that provide the optimum heat collection angle according to the application. and at least a predetermined side thereof is the installation surface of the solar collector.

An embodiment of this invention will be described below based on the drawings.

FIG. 1 is a perspective view of an embodiment of the solar collector mount according to this invention, and FIG. 2 is a perspective view of the oblique side of FIG. 1.
FIG. 2 is a cross-sectional view taken along line II.

In addition, FIG. 3 is a front view showing the embodiment shown in FIG.
The figure is a side view showing the same embodiment, and FIG. 5 is a plan view showing the same embodiment.

As shown in these figures, the solar collector mount 1 has a predetermined width, and as shown in FIG. shape, and at least two of the internal angles α, β, and γ are set at the optimal inclination angle for heat collection depending on the application such as heating and cooling, i.e., α = 20 to 40° for cooling, and α = 20 to 40° for heating. In this case, β is set in the range of 45 to 65°, and the predetermined side C is configured to be used as the installation surface of the solar collector.

More specifically, the plate 2 has a T-shaped cross section as shown in FIG. 2, and the protrusion 3 is for reinforcing the strength of the plate 1.

This plate body 2 is formed into a triangular shape as shown in the figure to constitute the solar collector frame 1.

A predetermined number of through holes 4A, 4B, and 4C (four on each side in this embodiment) are drilled in each side A, B, and C of the pedestal 1, into which screws are inserted during installation. ing.

The method of using the solar collector frame constructed in this way is explained in the sixth section.
This will be explained with reference to FIGS. 9 to 9.

FIG. 6 is a perspective view showing the arrangement when the solar collector is installed on one side of the mount.

Moreover, FIG. 7 is a partial sectional view showing the arrangement when two solar collectors are installed on one side of the mount.

As is clear from these figures, the solar collector 5 is installed on one side C of the pedestal 1, and one side A or B is used as a ground plane.

Furthermore, when two solar heat collectors are installed, the solar heat collectors 5 are installed on both sides of the center of one side C, as shown in FIG.

When one solar collector 5 is installed, two frames 1 are used as shown in FIG. 8, and when three solar collectors 5 are installed, for example, as shown in FIG. As shown, four frames 1 may be used.

That is, n = 1.2.3......, this n
If is the number of solar heat collectors 5, then the required number N of frames 1 is given by: N=n+1 (1).

In other words, when installing three solar collectors as in the case of Figure 9, n=3, so from equation (1), N=3+
1=4 pieces.

In this way, when 1'l=3, if two frames are required for each frame, the number N' of frames 1 is N'=2n, so N'=6 is required.

However, since it is installed as described above, N=4
become individual.

In other words, the relationship is N'-N=2n-(n+1)=n-1.

How to determine the angle of inclination will be explained below with reference to FIGS. 10 to 12.

FIG. 10 is an explanatory diagram showing an example of use that provides an optimal inclination angle for collecting heat for cooling, and FIG. 11 is an explanatory diagram showing an example of usage that provides an optimal inclination angle for collecting heat for heating.

Moreover, FIG. 12 is an explanatory diagram showing an example of use in which a solar collector is installed vertically.

In the example shown in these figures, α=35°, β=5
5°, γ-90°, and the reference numeral 5 designates a solar collector.

First, regarding heat collection for use in cooling, as shown in Fig. 10, one side B of the triangular frame 1 is used as the ground plane.
If the solar collector 5 is installed on one side C, the solar collector 5 can have an inclination angle of 35°, which is optimal for collecting heat for cooling.

Next, regarding heat collection for heating, as shown in FIG. 11, one side A of the triangular frame 1 is the ground plane, and one side C
If the solar heat collector 5 is installed in the solar heat collector 5, the inclination angle of the solar heat collector 5 can be set to 55°, which is optimal for collecting heat for heating.

In addition, FIG. 12 shows one side A of the triangular frame 1 as the ground plane and a solar collector 5 installed on one side B, and is an installation example when the solar collector 5 is used vertically. .

As described above, since the embodiment of this invention can be used, the number of parts can be significantly reduced, the weight can be reduced, and furthermore, mass production can be achieved, so that costs can be reduced.

Although the plate 2 has a T-shaped cross section as shown in FIG. 2, it may have a T-shaped cross section as shown in FIG.

In short, since the plate is made thin to reduce weight, its cross-sectional shape does not matter as long as it can provide the reinforcing effect.

FIG. 14 is an explanatory diagram of a case where pipe shafts for holding solar collector pipes are provided at each corner of a triangular frame.

In the figure, each corner of the projecting piece 3 of the frame 1 has through holes 6A and B.
and 6C are drilled, for example, one side B is the ground plane,
When the solar collector 5 is installed on one side C, the inflow pipe 7 can be inserted into the through hole 6A, and the outflow pipe 8 can be inserted into the through hole 6B.

In the case of the plate body 2 having a T-shaped cross section, the through hole 6 may be formed by simply drilling the through hole 6 as shown in FIG. It is constructed as if it were provided with a shaped portion 6M.

Further, in the case where the through hole 6 has a shape in cross section, a cylindrical portion 6M having the through hole 6 may be provided as shown in FIG. 17.

The through holes 6A and 6B can be used as pipe shafts, and the through holes 6C can be used for reverse return.

In this embodiment, the shape of the pedestal 1 has been described as a right triangle, but it goes without saying that other triangular shapes may be used.

In short, it is sufficient that the optimum inclination angle values are set for at least two of the interior angles of the triangle.

As described above, according to this invention, a solar collector is formed into a triangular shape with a plate of a predetermined width, and at least two of the interior angles are set at an angle of inclination that is optimal for heat collection depending on the application. The solar collector is set on each side, and the designated side serves as the installation surface for the solar collector, which reduces weight, improves durability and reliability, and reduces cost, creating the optimal slope for heat collection according to the application. This has the effect that it is possible to obtain a stand for a solar collector in which the corners can be obtained with one unit.
