Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved technique for a conventionally well-known heat collector, particularly a flowing-down heat collector.

1 and 2 of the accompanying drawings illustrate an embodiment of a heat collector according to the present invention. The heat collector according to the present invention includes a box-shaped heat receiving space 3 whose upper part is covered with a transparent plate 1 and whose lower part is covered with a heat insulating material 2, and a water supply means 4 (in the illustrated example, Although the water supply means 4 is shown as a pipe inserted into the heat receiving space 3, any other means such as a spray nozzle, gutter, etc. can be used) and the heat receiving space 3.
Hot water collection means (not shown) located below the space and collecting the hot water that has flowed down the front wall 3a of the space.
and a water sprinkling device 6 for receiving and sprinkling water supplied from the water supply means. The water sprinkling device consists of one end 6a for scooping out water that is in close contact with the rear wall 3b of the heat receiving space, and the other end 6b in contact with the front wall 3a of the heat receiving space 3,
The other end portion alternately includes portions 7a that contact the front wall of the heat receiving space and recessed portions 7b with a slight gap between the front wall and the front wall.

By configuring as described above, a part of the water supplied from the water supply means 4 comes into direct contact with the front wall 3a, and the remaining part is temporarily sent to one end 6a of the water sprinkler 6 in contact with the rear wall 3b. The water is collected and flows down through a recess 7b set between the other end 6b and the front wall 3a, forming a plurality of water columns that adhere to the front wall surface and flow at intervals. Therefore, even if the amount of water discharged from the water supply means is relatively small, water columns are formed at approximately equal intervals on the front wall surface, and a small amount of supplied water can be spread over a wide area on the front wall surface. According to the configuration of the present invention, in which the water supplied from the water supply means is rectified and deposited on the front wall, even if the supplied water is relatively small, heat exchange is made uniform over the entire front wall, Even if the wall has a wide area, it is possible to construct a heat collector at an extremely low cost compared to a conventional water pipe system.

Incidentally, the recess 7b of the other end 6b of the sprinkler device 6 described above may be formed by bending the tip into a branch shape as shown in FIGS. 1 and 2, or into a groove shape as shown in FIG. It can be manufactured by press molding. However, the shape of the recess may be any shape other than the one shown. Further, the water sprinkler is provided with a side edge and configured in the form of a gutter, and the water collected at one end 6a is temporarily collected in the gutter and then flows into the recess 7b at the other end 6b.
It may also be configured such that water overflows and adheres to the front wall. Furthermore, the water sprinkler can be installed at a position other than the one shown in the figure, for example, at the center of the heat receiving space as indicated by the two-dot chain line 8.

Claims (1)

[Scope of Claim for Utility Model Registration] A box-shaped heat receiving space whose upper part is covered with a transparent plate and whose lower part is covered with a heat insulating material, a water supply means provided above the heat receiving space, and a water supply means located below the heat receiving space. It has a hot water collecting means for collecting hot water flowing down on the front wall surface of the space, and a water sprinkling device that receives water supplied from the water supply means and sprinkles it, and the water sprinkling device is arranged in the heat receiving space. It consists of one end that scoops out water that is in close contact with the rear wall, and the other end that contacts the front wall of the heat receiving space, and the other end has a part that contacts the front wall of the heat receiving space and a part that contacts the front wall of the heat receiving space. A solar heat collector with alternating recesses and recesses with a slight gap between them.
