Description

[Detailed description of the invention] (Industrial field of application) The present invention is a technology for incorporating a heat collector into a structure using a roof surface such as a tile rod roof or other support surface of the structure, especially a long It relates to a built-in structure using a reusable solar collector that can be repaired and reused by removing the bottom sheet material after a period of use, cleaning the interior, making necessary repairs, and pasting the sheet material again.

(Prior art) Heat collectors that collect heat by forming bags of various structures using resin sheets and storing water in the bags are disclosed, for example, in Utility Model Application Publication No. 114364/1983 and Publication of Utility Model Publication No. 39/1989.
It is well known from No. 28993. These heat collectors belong to the disposable plastic bag type heat collectors, and are virtually impossible to repair and have to be discarded after being used for a relatively short period of time. Although various other bag-type heat collectors have been developed, these products are designed to be replaced periodically, and nothing that can be reused repeatedly for a long period of time has yet to be developed. do not have. When using a part of the roof as a roof with a built-in heat collector, if the service life of the heat collector can be extended at least as long as the period of use of the roof (for example, about 30 years) through repair/maintenance of the heat collector. Heat collectors are expected to become popular rapidly. In order to proactively incorporate this idea of repair/reuse into the structure of the heat collector, and at the same time to make it an inexpensive heat collector that can be used as a cost-saving facility, what kind of ingenuity should be put in place for flat-plate collectors? It is the applicant's understanding that this is a current issue with heating appliances.

(Means for solving the problem) In this invention, the part exposed to sunlight is made of a material with excellent weather resistance, and the casing part located on the back side of this exposed part is made of waterproof material, although it has relatively poor weather resistance. The above-mentioned problems are solved by using inexpensive materials that are easy to process/can be easily removed and reattached, and by incorporating a structure that takes advantage of the characteristics of each material.

According to the present invention, a recess into which the heat collector is inserted is formed by a support surface such as a roof on which the heat collector is placed, and holding members protruding from the support surface and arranged on both sides of the heat collector. In this recess, there is an opening in the bottom with a heat receiving body for heat exchange that receives solar heat on the outer surface and transfers the heat to the heat medium flowing down the inner surface, and a side wall located around this heat receiving body. A heat collector consisting of a weatherproof case and a sheet material that closes the opening of the case and whose peripheral edge is pasted along the outer surface of the side wall of the case to form a waterproof tub is inserted, and the heat collector is removed from the holding member. A solar collector built-in structure that can be used repeatedly is obtained, which is characterized in that the housing is held down substantially from above by a holding member and fixed in a predetermined position with the heat receiving body of the housing exposed to the outside.

(Example) FIG. 1 is a perspective explanatory view showing an example of a reusable solar collector built-in structure according to the present invention. The illustrated flowing-down solar heat collector includes a housing 1 which is one element forming a substantially sealed space 5, and a housing 1 which is placed above the sealed space 5, and which supplies a heat medium to the back surface of a heat receiving body 2. It is provided with a liquid supply means 6 (indicated by dotted lines) for depositing and flowing down, and a suitable liquid drain port (not shown) for taking out the heating medium.

The housing 1 includes a side wall 3 that is continuous with a heat receiving body 2 facing the sun, and the side wall forms a downward opening. This opening forms the other element, the flexible sheet material 4, which forms a substantially sealed space 5.
covered by.

FIGS. 2 to 4 are explanatory diagrams showing the state of bonding between the side wall 3 of the heat receiving body and the peripheral edge of the sheet material.
The heat receiving body has rigidity against external loads, and the peripheral edge of the sheet material 4 is adhered to the side wall 3 of the heat receiving body to close the downward opening of the heat receiving body and form the bottom of the casing, creating a substantially sealed space. 5 is formed.

In the example of FIG. 2, the peripheral edge of the sheet material 4 is directly adhered to the side wall 3 of the heat receiving element with a single layer thickness, but in the example of FIG. 3, the sheet material 4 has a triple thickness and In the example shown in FIG. 4, a weather-resistant cover 7 further covers and protects the adhesive layer.

FIG. 5 is an explanatory diagram showing the above-mentioned heat collector installed in a recess of a tiled roof. The collector may be incorporated into the support surface, for example as shown, and held in place using fasteners such as those indicated by reference numeral 8.

(Effects of the invention) As described above, the flowing-down solar collector according to the invention takes advantage of the characteristics of the housing material, which is highly weather resistant, and the sheet material, which is not exposed to direct sunlight. be able to. It is possible to provide a heat collector that is extremely easy to process, easy to repair, lightweight, and inexpensive. If repairs are repeated appropriately, the service life of the heat collector is semi-permanent.

A heat collector can be easily incorporated into an existing facility, such as a tiled roof, making it possible to construct a highly economical solar system with significantly lower initial costs and lower maintenance and management costs.
