Description

[Detailed description of the invention] The present invention relates to the invention of a solar heat collector, which makes it possible to effectively connect and arrange a plurality of solar heat collectors in a tiered manner for efficient heat collection. It also aims to make the connection structure more precise.

Various heat collectors have been proposed and put into practical use to collect and utilize solar heat, but in order to achieve efficient heat collection, the heat collecting plate installed inside the frame must be covered with a solar heat transmitting plate. Conventionally, such heat collectors are usually installed on a special pedestal on the roof, and the structure for setting it up is difficult. It is complicated and large, and the connection structure when connecting multiple heat collectors installed in this way with connecting pipes requires providing the connecting pipes by bypassing the solar heat transmitting plate part provided on the top surface. Therefore, it cannot help but become complicated.

The present invention eliminates the above-mentioned disadvantages of the conventional method, and also enables a new and advantageous connection of heat collectors. At the same time, a heat collecting plate in which both ends of the arrayed pipes are connected to a common pipe is installed in a frame body with a solar heat transmitting plate attached to the upper surface, and the above-mentioned common pipe part is attached to one side of the frame. A covering extension frame is provided, a first inlet/outlet is formed upward in the extension frame to connect with one common pipe line located at the lower part of the extension frame, and a first entrance/exit is formed upward to connect to the other common pipe line located on the other side of the frame body. proposes a solar heat collector characterized in that the second entrance and exit are connected downward, and a support portion for the solar heat transmitting plate is formed at the end of the extension frame.

That is, an embodiment of the present invention as shown in the attached drawings will be described. A parallel pipe line 2a through which a fluid to be heated such as water or air flows is arranged, and the parallel pipe line 2
A heat collecting plate 2 having both ends thereof connected to a common pipe line 5 is installed in the frame body 1, and an extension frame part 1e is provided on one side of the frame body 1 to cover one of the above-mentioned common pipe line parts. A first inlet/outlet 6 is provided upward in the extension frame portion 1e to connect with one common conduit located at the lower part of the extended frame portion 1e, and the other common conduit 5 located on the other side of the frame 1 is provided with a first inlet/outlet 6 facing upward. is the second entrance/exit 6a
is provided facing downward, and the support portion 31 for the solar heat transmitting plate described above is formed at the end of the extension frame 1e described above.

In the illustrated example, a heat insulating plate 4 is attached to the bottom surface of the frame 1, but such a heat insulating plate 4 and transparent plate 3 are attached to the second to second parts.
As shown in FIG. 5, the parallel pipe line 2a and the common pipe lines 5, 5
are attached to the bottom and top surfaces of the

Also, as shown in the figure, the heat collecting plate 2 and the solar heat ray transmitting plate 3 are attached to the frame 1 with backing materials 7 and 9 interposed at their edges, and the above-mentioned extension frame portion 1e is can be formed integrally with the frame 1 depending on the case, but since the inner hole of the common pipe line 5 as described above is larger than the parallel pipe line 2a, it is formed into an elliptical shape as shown in FIGS. 2 to 4. It is formed in the shape of an ellipse so that its top or bottom surface is located in the same plane as the conduit 2a.

The heat insulating board 4 described above is made of a heat insulating material having appropriate strength, such as a hard urethane foam board, an asbestos calcium silicate board, an asbestos slate board, or a composite material of a soft heat insulating material and a strength material.

Further, the heat collecting plate 2 described above is coated with a black color or a similar coating or film, but is preferably treated with a selective absorption film to obtain a sufficient heat collecting effect and to reduce the amount of heat dissipated as much as possible. The material used is synthetic resin, aluminum, stainless steel plate, etc., and the pipes 2a and 5 as described above are formed on the plate material and then overlapped and glued together, or separate pieces. For example, an aluminum plate electrolytically colored black may be used.

The material of the concrete prototype made by the present inventors is a synthetic resin for the heat collecting plate 2, and a reinforcing plate 4b is used as the heat insulating material 4 on the back side of the soft urethane foam as shown in FIG.
We were able to obtain a product that was relatively thin and had appropriate strength, making it suitable for handling and construction.

In view of the purpose of construction, the mounting seat 21 is integrally formed in a part of the frame 1, and the mounting seat 21 is fixed to a desired setting surface using a stopper 19, as shown in FIG. Regarding the configuration of the overlapping part as shown in FIG. 3, the frame 1 of the heat collector located at the lower stage is separately shown in FIG. 4.
A support seat 21a is formed to support the bottom surface of the upper heat collector, and in this state, the entrances and exits 6, 6a are connected.

This connection may be made by inserting one entrance/exit 6 into the other entrance/exit 6a as shown in FIG. A joint body 24 is used as shown in FIG.

One example of concrete connection construction using the heat collector of the present invention as described above is as shown in Figure 6 and below.A tank 10 is installed at the ridge of the roof of a building such as a house, and the direction of the roof is adjusted. In consideration of this, on both sides of the roof surface 11, the heat collectors according to the present invention are connected and arranged in rows as shown in FIGS. 6 and 7 in the same way as for roof tiles. The inlet/outlet 6 provided on the upper surface is connected to the inlet/outlet 6a of the tank 10 or the upper heat collector with a structure as shown in FIG. 3 or FIG.
0, a roof 11 (thereby piping 12 is provided).

Regarding the horizontal connection of each heat collector, see Figures 8 and 9.
As shown in the figure, locking portions 13 are provided oppositely on the outside of the frame 1, and nuts 15 and locking plates that are appropriately engaged with the backing material 14 and the groove portion 18 are attached to these locking portions 13, 13. 1
6, the upper side frame of each heat collector can be fixed to the roof with the stopper 19 of the mounting seat 21 as shown in Fig. 3. In this way, the device according to the present invention can be used as a substitute for tiles or similar exterior roofing materials, and at least as a support stand or other support when a heat collector is installed on the roof as in the past. A stable installation can be obtained by completely eliminating the need for setting members.

It is clear that a similar relationship to the above can be obtained even when it is attached to a side wall surface or the like.

According to the present invention as explained above, conduits for circulating fluid are arranged in a row, and both ends of the arranged conduits are connected to a common conduit, respectively, and a heat collecting plate is provided with a solar heat transmitting plate on the top surface. It is clear that efficient heat collection can be achieved by the heat collecting plate because it is provided inside the attached frame, and one of the common pipe sections mentioned above is attached to one side of the frame as described above. An extension frame is provided to cover the extension frame, and a first inlet/outlet is provided in the extension frame to connect with one of the common pipes located at the lower part of the extension frame, so that the first inlet/outlet is properly attached to the frame, and the second for the other common conduit located on the other side;
Together with the inlets and outlets of the pipes, the fluid can flow smoothly through the lined pipes as described above, and the heat collectors are arranged in stages and connected to each other as shown in Fig. 3 or 4. It has the effect of achieving a stable and strong connection and installation by using the extension frame part even when it is used, and is a highly effective idea in practical terms.
