Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a temporary or portable pumping type solar collector.

[Prior Art] A conventional pump collector type solar collector of this type has a structure in which water is stored in a vinyl resin bag and exposed to direct light.

[Problems to be solved by the invention] Such a water-filled bag has poor pressure resistance and has a drawback that water leakage occurs due to deterioration of the material and a relatively short use.
In addition, it is difficult to repair water leaks and the service life is generally short. Further, it is practically difficult to manufacture a large-sized one (a large-capacity one).

[Means for Solving the Problems] A solar collector according to the present invention uses a flexible sheet material and has an open container at the upper part for pumping and storing a heat carrier liquid, and a rear part of the container. A heat receiving surface that is continuous with the wall and extends substantially upward is formed to support an appropriate place so that the whole is self-supporting. The heat carrier liquid is sprinkled on the heat receiving surface,
The heat medium liquid that has absorbed the heat of the heat receiving surface is stored in the pump container. The front of the heat receiving surface and the opening of the container are covered with a transparent sheet to obtain the greenhouse effect, and a simple structure combining the features of the downflow collector and the pool collector is provided.

[Operation] According to the above-described structure, it is possible to obtain the pumping heat collector having an extremely simple structure in which the heat receiving surface and the storage tank are continuous. An extremely wide heat receiving surface is obtained as compared with the conventional pumping type, and the pumped heat carrier liquid is further heated by the greenhouse effect and / or direct solar radiation.

Absolutely watertight structure like the conventional water bag is unnecessary, and even if the material breaks, it can be easily repaired by adhering a reinforcing seal cloth, etc., and the inside can be easily cleaned regularly. be able to.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Example] In the example shown in FIG. 1, the solar collector 1 according to the present invention is used.
Comprises a container 2 having an upper opening for drawing and depositing a heat medium liquid by using a flexible sheet material, and a heat receiving surface 3 which is continuous with a rear wall of the container 2 and extends substantially upward, A transparent sheet 4 for obtaining a greenhouse effect is covered in front of the opening of the container 2 and the heat receiving surface 3, and a supply means 5 for spraying a heat medium liquid from a nozzle is arranged on the heat receiving surface in the greenhouse space. is there.

The heat medium liquid is sprinkled on the heat receiving surface 3 by using a heat medium liquid supply means 5 such as an injection nozzle or a nozzle pipe. In the illustrated example, the heat medium liquid is discharged from the injection nozzle in a fan shape toward the upper end of the heat receiving surface, and the heat medium liquid thus discharged flows down along the heat receiving surface while removing heat and collects in the container 2. .
The heat carrier liquid collected in the container 2 receives the direct light of the sun and further absorbs heat, and is pumped to the supply means 5 as necessary, and repeatedly dispersed on the heat receiving surface 3.

When tap water is used as the heat transfer fluid, a timer is used to open and close the solenoid valve intermittently, and tap water is used to regularly spray tap water onto the heat receiving surface, and the water is then stored in the container by the end of heat collection. It is also possible to operate so as to collect a predetermined amount of warm water, or in addition to such operation, or separately from such operation, water accumulated in the container may be repeatedly sprayed on the heat receiving surface.

In the example of FIG. 1, one sheet material having a rectangular shape is used, and the portion located at the side end of the container 2 is squeezed to form the side edge of the container without using the welding technique as much as possible. It is good to devise. In the illustrated example, the drawstring 6 is incorporated along the edge of the sheet material corresponding to the side edge of the container.

The embodiment shown in FIG. 2 shows a constitutional example in which the support layer 7 for reinforcement is applied along the heat receiving surface 3 and the back side of the container 2 so that a large tensile load is not applied to the sheet material. . When such a method is adopted, it is convenient that the sheet material can be attached to the surface of the support layer with one touch using a magic tape or the like.

As the sheet material, for example, various flexible sheet materials such as a fiber reinforced resin sheet and a rubber sheet are selectively used.

The sheet material preferably has sufficient heat insulating properties to reduce the amount of heat radiation from the lower surface. For example, a soft urethane foam layer may be adhered to the back side of the sheet material. It is of course possible to cover the upper side of the transparent sheet 4 with the heat insulating cover 8 in a necessary time period in order to suppress heat radiation after the heat collection is completed.

If the sheet material and the transparent sheet are devised so that they can be attached and detached as needed, the inside can be regularly cleaned, which is convenient.

The above-mentioned sheet material can be supported by using a suitable mount. The support structure for the sheet material can be arbitrarily selected.

[Advantages of the Invention] With the configuration as described above, it is possible to obtain temporary equipment which is excellent in portability and can be installed or assembled quickly.

Further, according to this structure, it is possible to obtain a pumping heat collector having an extremely simple structure in which the heat receiving surface and the storage tank are integrated regardless of the size of the sheet material. Moreover, since the heat receiving surface is practically made of a continuous sheet material, the area can be freely set. The hot water storage capacity can be freely selected as well.

Furthermore, an absolute watertight structure such as a conventional water bag is unnecessary, and even if the material is broken, it can be easily repaired by adhering a repair seal cloth.

According to the present invention, it is possible to obtain a very simple, yet low-priced heat collector with a large amount of heat collection, which can be used for accommodation facilities such as coastal resort areas and tourist areas in the mountains.
It is possible to provide temporary equipment for seasonal specifications except in winter.
