JPS5834380Y2 - Outline of solar heat collector - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to the outline of a solar heat collector that uses a residential fence, balcony, etc. as a solar heat collector, and aims to obtain the outline of the fence with increased strength.

Conventionally, when solar heat collectors are used on fences, balconies, etc., the main structure that holds the solar heat collector and the water pipes is to house the water pipes in a frame with a U-shaped cross section. A heat insulating material is filled around this water pipe, and the water is distributed to the solar heat collector.

The conventional skeleton with a U-shaped cross section has low strength. For example, when a fence is used as a solar heat collector and several solar heat collectors are connected, the whole structure is twisted, and the skeleton is weak against the solar heat collector. It had drawbacks such as misalignment and being weak against loads from the father.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a frame portion having a U-shaped cross section. On the inner lower surface of this frame portion 1, engaging portions 2, 2' are provided on both sides, and four portions 3, 3' are formed.

Reference numeral 4 denotes a water pipe, which is located at the center of the vessel, and is provided with holding pieces 5 and 5' for holding the water pipe 4. These water pipe 14 and the engaging parts 2 and 2' holding pieces 5.5 ’ is the frame part 1, respectively.
It is formed in one piece and manufactured by extrusion molding.

6 is a heat insulating material storage portion of the frame portion 1 formed integrally with these; 7
is a connection hole provided in the water pipe 4, and is connected to the heat collection pipe 1 of the heat collector.
8 is a bushing connected to 7, and a groove 9 that engages with the connection hole 7 is provided approximately at the center of the outer periphery.

10 is a through hole provided in the bushing 8, which is a through hole provided in the bushing 8,
7 is provided so as to penetrate therethrough.

Also, the bushing 8 is inserted from the groove 9, and the upper part is inside the water pipe 4.
The lower part is located outside the water pipe 4.

13 is a reinforcing plate, which has an engaging protrusion 15°1 with respect to the flat part 14.
5' is provided, and these protrusions 15, 15' are provided with recesses 3, 3'.
By engaging, even when a load is applied from above the frame 1, it spreads outward and does not come off the convex part 15 of the reinforcing plate 13, and even in the inward direction, the convex It is made so that it does not deviate from part 15.

Reference numeral 16 denotes a through hole, which is formed in a size large enough for the heat collecting tube 17 and the nut 20 to pass through.

A widening section 18 is machined at the tip of the heat collecting tube body 17, and it is made to widen like a flare, and is made slightly larger than the inner diameter of the through hole 10 of the bushing 8, so that it can be inserted by pushing firmly. .

19 is a threaded portion into which the nut 20 is screwed;
are provided only near the upper and lower ends 22 of the heat collector frame 21, and are formed so that the nuts 20 are screwed together.

23 is a heat insulating material, 24 is a heat collecting plate, and 25 is a transparent body, which becomes a surface that receives solar heat.

26 is the solar heat collector main body 27 is the insulation material storage part 6 of the frame part 1
28 is a lid that covers the openings made at the top and bottom of the back side of the solar heat collector 26 for tightening the nuts 20, and is attached to the back side of the solar heat collector 26 with screws 29. ing.

Reference numeral 30 denotes a heat insulating material that is filled into an opening opened to tighten the nut 20.

In the above configuration, when assembling the fence, the heat collecting pipe 17 of the solar heat collector 26 is passed through the through hole 16 of the reinforcing plate 13, and is further attached to the connecting hole 7 provided in the water pipe 4 of the frame part 1. The bushing 8 is inserted into the through hole 10 of the bushing 8, and then tightened with a nut 20 from the opening provided on the back side of the solar heat collector 26. The heat collecting pipe 17 and the water pipe 4 are connected while being compressed and deformed.

After tightening the screws 20, the insulation material 30 is filled, and the lid 28 is attached with the screws 29, completing the fence assembly.

As described above, according to the present invention, there is provided an engaging portion that engages with a protrusion formed on the reinforcing plate toward the inside of the lower surface of the frame, and a water pipe held by a holding piece in the center portion. Because there are
The strength is increased by the holding pieces, and the frame body is prevented from deforming inwardly and outwardly by being secured to the reinforcing plate, so that the fence will not be deformed even when used as a drying area.

Furthermore, since the water pipe is integrally provided in the frame, there is an advantage that there is no need to provide separate piping.
