Description

[Detailed Description of the Invention] The present invention relates to a solar heat collector in which a heat collecting plate and a box body are integrally molded from synthetic resin.

As one type of solar heat collector, there is a synthetic resin collector integrally molded by, for example, a clam shell molding method. This has many advantages such as being easier to manufacture, lower cost, superior corrosion resistance, and lighter weight than other collectors in which the metal heat collecting plate and box body are manufactured separately and assembled together. It has the following advantages.

However, as shown in Figure 1, solar collectors made using the conventional clam shell molding method have a vertical shape, so when installing multiple solar collectors in parallel to obtain higher temperature water supply, the following methods are recommended: There were some problems.

(1) Connection piping like the one shown in Figure 2a is vertically long and cannot be installed on the roof of an ordinary house.

(2) If they are arranged horizontally in parallel so that they can be mounted on the roof, it will be difficult to drain water from pipes as shown in Figure 2b when they freeze.

(3) Alternatively, as shown in Figure 2c, piping using a header will make draining easier, but will complicate the construction and increase the cost of piping materials.

In the present invention, the above problem has been solved by making the solar collector horizontal, but the following problems still remain.

That is, if the collector inlet 2 and collector outlet 3 are provided in the center so as to easily connect a plurality of solar collectors in series as shown in FIG. 3a, water will not flow uniformly. Also, to prevent this,
To create a connection piping as shown in Figure 3b, two types of solar collectors, A and B, are required, and two types of molds are also required.
This would be a huge economic disadvantage.

The present invention provides a solar heat collector that solves the above problems, and the structure, operation, etc. will be explained below based on one embodiment shown in the drawings.

FIG. 4 is a perspective view of a solar collector according to the present invention, in which 1 is a transparent body, 2 is a collector inlet, and 3 is a collector outlet. FIG. 5 is a sectional view of the solar collector shown in FIG. 4, where 4 is a fluid passage, 5 is a side wall body, 6a is a bottom member with a heat insulating material 6 provided on the front, 7 is a sealing member for the inlet/outlet pipe part, 8 is the collector body,
9 is the greenhouse section.

The solar heat that passes through the transparent body 1 reaches the heat collection surface and heats the liquid flowing in the fluid passage 4. in this case,
Dissipation of heat upward is suppressed to a minimum by the greenhouse section 9 constituted by the transmitting body 1, the side wall body 5, and the heat collecting surface. The sealing member 7 has the effect of sealing the recesses at the collector inlet 2 and collector outlet 3 that are created when the solar collector is made by clam shell molding, thereby improving the greenhouse effect. on the other hand,
Dissipation of heat downwards is reduced by a heat insulating material 6 mounted below the heat collecting plate.

As described above, in the solar heat collector, the greenhouse section 9 on the heat collecting surface plays a major role in heat retention. In the solar heat collector according to the present invention shown in FIGS. 4 and 5, the line C-C connecting the centers of the fluid passages 4 is made to be approximately at the center of the height H of the collector, so that It can be used as a heat collecting surface by pasting the transparent body 1, or as a heat collecting surface by pasting the transparent body 1 on the B side.
An effective greenhouse effect can be obtained.

As shown in FIG. 6, when a plurality of collectors 1 and 2 are connected in succession in a plane, the first collector has the transparent body 1 disposed on the B side and the bottom member 6a on the A side. On the other hand, in the second collector body, the transparent body 1 is placed on the side A, and the bottom member 6a is placed on the side B, so that both the first and second collector bodies have the transparent body 1 side placed on the side B. Place it facing the top side.

In this way, the first and second collectors will be
The collector main body 8 is in a reversed relationship, so that the inlet 2 and the outlet 3 of the collector are provided diagonally on the long side of the collector main body 8.
However, the relationship between the first collector and the second collector is such that the left and right sides are reversed.

Therefore, as shown in FIG. 6, when collectors A and D are connected by a short straight pipe 10, two types of collectors with the inlet and outlet positions interchanged on the left and right are required. By swapping the positions of the inlet 2 and outlet 3 of the collectors C and D to the left and right, it becomes possible to connect the piping 10 continuously in a plane with one type of collector, as shown in FIG. 6. .

As described above, the present invention is a rectangular solar heat collector in which a transparent body is provided on one of the upper and lower surfaces of the collector body, and a bottom member is provided on the other side, and a plurality of solar heat collectors are connected in succession in a plane. In this case, the transmitting body and the bottom member are provided to be replaceable with respect to the collector body, the collector inlet and the collector outlet are provided on both long sides of the collector body, and the relationship between the collector inlet and the collector outlet is diagonal to each other. , is a solar heat collector characterized in that the shape of the collector body is formed to be approximately vertically symmetrical with respect to a line connecting the centers of the fluid passages.

Therefore, when installing a plurality of solar heat collectors, the collector body of the first solar heat collector is inverted, and the collector body of the first solar heat collector is inverted, and the collector body of the first solar heat collector is inverted. A second collector can be formed by providing a transparent body on the upper surface side of the main body and a bottom member on the lower surface side.

As a result, in comparison with the first solar collector, the second solar collector is formed as a collector in which the collector inlet and outlet provided on the long side of the collector body are swapped between the left and right sides,
By connecting the first and second solar heat collectors in a continuous manner in a plane, the following effects can be achieved.

a Since the positions of the outlet and inlet on the long sides of the first solar heat collector and the second solar heat collector are swapped left and right, the first and second solar heat collectors are in a state facing
By connecting the outlet of the first solar collector and the inlet of the second solar collector, the short sides of the first and second solar collectors coincide in the longitudinal direction, and as a result, in the lateral direction The increase in installation space can be suppressed.

b In the case of connecting the first and second solar heat collectors, the outlet of the first solar heat collector and the inlet of the first solar heat collector coincide, so the inlet,
The piping connecting the outlet should be short and straight. Therefore, the space between the first and second solar collectors is small, and as a result, it is possible to suppress an increase in vertical installation space.

c As mentioned above, the first and second solar collectors can be connected in a continuous manner in a plane, and the piping material connecting the collectors can be made short and straight, so it is possible to install multiple solar collectors. Draining water from the collector is extremely easy.

d As mentioned above, since the collector body can be used by inverting it, only one type of collector is manufactured even though two types of collectors are required for connection. This makes it possible to reduce manufacturing costs, such as saving mold costs.

e) The piping connecting the inlets and outlets of the first and second solar heat collectors can be made short and straight, making piping work simple.
