Description

[Detailed description of the invention] This invention is a solar heat treatment system that prevents the collector stored in the collector case from expanding or contracting due to solar heat, or from deformation of the collector or damage to piping connections due to impact during transportation. Regarding a heat collection device.

In recent years, solar energy has been reconsidered as oil prices have gone up, but rather than focusing on energy efficiency and exergy efficiency, there has been a demand for the development of inexpensive solar systems.

In this respect, resin collectors are not only inexpensive, but also have superior properties compared to metal collectors in terms of corrosion resistance against water.

However, resin collectors have a larger coefficient of linear expansion than metals (for example, 1 to 2.5X 10-', which is very large; for example, in a collector with a size of l x 2 (rrL), it has a coefficient of linear expansion of 32.5 The expansion and contraction of stiffness can be considered.

), its expansion and contraction structure becomes complicated, and the structure of the water inlet and outlet also becomes complicated.

That is, in the conventional solar heat collecting device shown in FIG. 1, a rectangular collector 1 is placed in the center of a collector case 2, the periphery of the collector 1 is separated from the sides of the collector case 2, and collector holders 3, 3, The collector 1 is fixed to the collector case 2 at....

4.4 is a waterway formed in the collector 1, which communicates the inlet vibe 5 and the outlet vibe 6 of the collector 1.

When the collector 1 is exposed to the blazing sun, the collector 1 expands and becomes larger due to thermal expansion.

Therefore, the positions of the inlet vibrator 5 and the outlet vibrator 6 change depending on the temperature.

Therefore, it is necessary to make an elliptical hole or the like in the collector case 2, and to create a structure in which the collector holder 3 can be moved in the direction of expansion and contraction as the collector 1 expands and contracts, making these structures complicated and reducing reliability. It was something lacking.

The present invention eliminates the above-mentioned drawbacks and provides a solar heat collecting device which has a simple structure, maintains the normal condition of the collector, and withstands temperature.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.

In FIG. 2, a collector 1 made of resin is provided in contact with the right side and lower side of a collector case 2, and its corners 7 are fixed to the collector case 2 by fixing screws 8, 8.

Reference numeral 9 denotes a flow pipe protruding from the corner 7 of the collector case 2.
It protrudes through an insertion hole 2a bored on the right side.

The collector 1 has a space 10.10 between the left side and the upper side of the collector case 2, and the collector presser 3.3... allows for upward and downward movements (perpendicular to the plane of the paper). direction) is regulated.

Reference numerals 4 and 4 denote water channels of the collector 1, which are combined into one water channel 11 and connected to an outlet vibe 13 provided at a corner 12 of the collector 1.

14 is a hole 14a formed on the right side of the collector case 2.
A hot water supply pipe is fixed to the outlet pipe 13, and is connected to the outlet vibe 13 through an expandable, loose flow pipe 15.

16 and 17 are hose bands for fixing both ends of the flow pipe 15.

The above-mentioned flow pipe 15 has a notch 1 formed on the right side of the collector 1.
8, there is no need to enlarge the collector case 2.

That is, if such a notch 18 is not provided, the flow pipe 15 must be provided between the left side (upper side) of the collector 1 and the left side (upper side) of the collector case 2.
Since a space 10 that is at least longer than the length of the flow pipe 15 is required, if the size of the collector 1 is kept constant, the size of the collector case 2 must be increased.

Reference numeral 19 denotes a repair window drilled from the upper side to the bottom of the collector case 2 corresponding to the notch 18, and is usually closed by an L-shaped cover 20 that is detachably attached to prevent heat from passing through. This prevents water from escaping and rainwater from entering.

Reference numeral 20a indicates a screw hole for attaching the cover 20, and reference numeral 20b indicates a clamping piece for fitting onto the bottom surface of the collector case 2.

21, 21. ... is a reinforcing angle screwed to the inside of the triangular part of the collector case 2.

Reference numeral 22 is a holding metal fitting that serves as a corner reinforcing angle and a receiver for the flow pipe 9, and is screwed into one corner of the collector case 2.

Since the flow pipe 9 is held by this holding fitting 22,
Even if the collector 1, collector case 2, etc. vibrate or fall during transportation, the flow pipe 9 remains stable and will not be damaged.

In such a solar heat collecting device, when one collector is heated by radiation, the left side and the upper side that are not in contact with the collector case 2 expand toward the space 10.10.

As a result, the outlet vibrator 13 of the corner 12 is also displaced upward and to the left, but this displacement is absorbed by the elasticity of the flow pipe 15, so the hot water supply pipe 14 can be fixed to the collector case 2. .

In addition, since the collector 1 is fixed to the collector case 2 at least near the corner 7 and the two sides forming the corner 7 are in contact with the collector case 2, the fixing state is also comparable to the conventional one. .

In other words, although the fixing structure of the collector 1 is very simple compared to the conventional one, it is possible to obtain the same fixing state as the conventional one.

Furthermore, there is no need to provide a structure (for example, providing an elliptical hole) to accommodate changes in the position of the tube in the collector case 2, which is also advantageous.

In addition, in the case of the heat collector of the present invention, if the flow pipe 15, hose bands 16, 17, and their connecting parts deteriorate due to changes over time due to long-term use, and phenomena such as water leakage occur, the cover 20 can be removed. These parts can be easily replaced.

If the cover 20 or the like is not provided, all the sashes attached to the collector case 2 and the tempered glass covering the surface will have to be removed at the time of repair as described above, resulting in a difficult work.

Therefore, providing the cover 20 and the repair window 19 may seem like a cost reduction at first glance, but when the above-mentioned circumstances are taken into account, it is actually extremely useful and has the same value as the cost reduction. It is something to give.

Moreover, if the metal fittings 22 are provided to hold the flow pipe 9 in surface contact,
Damage caused by collision between the flow pipe 9 and the collector case 2 that would otherwise occur can be prevented.

As shown above, according to the solar heat collecting device of the present invention, the mounting structure of the collector to the collector case is extremely simple, and it also sufficiently absorbs the expansion and contraction of the collector to prevent damage to the connecting parts, etc. can do.

Furthermore, by removing the cover, the expandable and retractable flow pipe etc. can be easily replaced and repaired.
