BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar heat collector header box.

[0002]

2. Description of the Related Art A conventional solar hot water supply system (10) comprises:
As shown in FIG. 7, a plurality of solar heat collectors (1) arranged in parallel with each other in the axial direction are arranged so that their axial directions are substantially perpendicular to each other, and a header pipe for water supply (2) and a header pipe for hot water (3). And connecting the base end of the inner pipe (4) projecting from one end of each solar heat collector (1) to the water supply header pipe (2) in the header box (6); The base end of the outer tube (5), which concentrically surrounds the inner tube (4) and protrudes from one end of the solar heat collector (1), is connected to the header tube (3) for tapping in the header box (6). )
By connecting the base ends of the water supply header pipe (2) and the tapping header pipe (3), and the inner pipe (4) and the outer pipe (5) in the header box (6). It is configured in a switching system. The inside of the header box (6) is filled with a heat insulating material (7) such as glass fiber or rock wool to keep the water supply header tube (2) and the tap water header tube (3) warm. The solar heat collector (1) is connected to the water supply header pipe (2) and the hot water header pipe (3) in each header box (6) as a set of three or four, and is required. A solar hot water supply system (10) is configured by connecting two or more sets of solar heat collecting devices (8) in series via a relay header box (6a) in accordance with the hot water supply capacity. still,
FIG. 7 illustrates a solar hot water supply system (10) including two sets of solar heat collectors (8) each including four solar heat collectors (1), but viewed upstream from the water supply direction. On the back side of the header box (6) of the solar heat collector (1) located on the side, a cistern (9) for water storage is connected via a water supply pipe (9a).

When two or more sets of solar heat collecting apparatuses (8) are connected in series to constitute a solar hot water supply system (10),
Each solar heat collector (8) connects the proximal end of the inner pipe (4) to the water supply header pipe (2) in a separate header box (6) and the proximal end of the outer pipe (5). The section is connected to a tapping header pipe (3). Then, a relay header box (6a) is disposed between the two header boxes (6) and separated from each other, and the inside thereof is filled with a heat insulating material (7), so that the left and right solar heat collectors are disposed. (8) The header pipe (2) for water supply and the header pipe (3) for tapping in (8) are insulated and protected.

[0004]

When the header box (6) and the relay header box (6a) as described above are used together, three header boxes separated from each other in a hexahedral structure are required. Is complicated and the number of assembling steps is increased, and the manufacturing cost is also increased. Further, since the relay header box (6a) whose side wall surface is similarly closed is disposed between the two header boxes (6) and (6) whose side wall surface is closed, In the facing area, not only is the side wall doubled, so that waste is increased, but also since the formation of a curved surface is difficult, design restrictions are increased.

[0005]

As a means for solving the above-mentioned problems, the present invention is characterized in that both sides are formed in an opening surface, and an insertion hole is provided at the front side of the solar heat collector at the header side end. The upper and lower body unit head covers of the upper and lower two-part structure having rainwater return protrusions formed over the entire length of the edge, and between the adjacent main body unit head covers, both sides are overlapped and connected and arranged. Over and over the entire length of the upper and lower two-part structure of the intermediate cover and the outer opening of the main body unit head cover, the rain cover is formed on the main unit unit head cover. A sun cover having a non-divided structure in which a rainwater return ridge overlapping with the rainwater return ridge of the main unit unit head cover is formed on the upper edge of the sun cover over its entire length. There is provided a heat collector header box.

[0006]

The header box of the solar heat collector is composed of a main body unit head cover and an intermediate cover having a vertically divided structure and a side cover having a non-divided structure. After wrapping a heat insulating material around the water supply header pipe and the hot water supply header pipe, fit the header side end of the solar heat collector into the insertion hole provided on the front side of the main unit unit head cover, and fix the solar heat collector. , Ie, the base end of the solar heat collector, the water supply header tube, and the hot water supply header tube, are gripped from above and below by the main unit unit head cover. Next, in a state in which the rainwater return ridge is superimposed on the rainwater return ridge provided on the upper inner edge of the main body unit head cover, a pair of upper and lower splicing is provided between two adjacent main body unit head covers. Attach the cover. Finally,
With the rainwater return ridge superimposed on the rainwater return ridge provided on the outer upper edge of the main unit head cover, the side cover is fitted from the side into the outer opening of the main unit unit head cover, The assembly work of the combined header box is completed by screwing the overlapping portions of the head cover, the relay cover, and the side cover. In the above-described example, two main unit head covers are used. However, the present invention is also used when only one or two or more head covers are used.
