Description

[Detailed explanation of the idea] The present invention relates to a solar heat collector.

A solar heat collection device that is installed on the roof consists of a heat collection panel containing detour wood pipes housed in a flat case with a transparent top lid, and a water storage tank.The water storage tank is placed on the top side of the heat collection panel. has been done.

The water storage tank and the wood pipes in the heat collection panel are connected to each other so that water can circulate.

When the water in the water pipe is heated, this heated water rises into the water storage tank due to the decrease in water specific gravity and reaches the water surface in the water storage tank, while the cold water at the bottom of the water storage tank migrates into the water pipes.

In this way, the warmed water in the water pipes is replaced with cold water, natural circulation takes place, and the inside of the water storage tank is filled with warmed water.

When the hot water in the water tank is used for hot water supply and the water level in the tank drops, water is supplied into the tank from the pole tap water inlet, and the water level in the water tank returns to a predetermined steady water level. will be recovered.

This steady water level is higher than the location of the wood pipe detour in the heat collection panel that is closest to the water storage tank.

In the above, even if the roof slope is different, the heat collection panel is required to be attached to the water storage tank at an appropriate inclination via a connecting rod so that the heat collection panel can be maintained at an optimal angle for collecting solar heat. In this case, a flexible tube must be used for the tube that communicates the water storage tank and the water pipe of the heat collection panel so that the appropriate installation angle of the heat collection panel can be accommodated. If the tube is an exposed type, there will be problems such as premature damage due to UV deterioration and tube breakage due to freezing inside the tube in winter.

The solar heat collecting device according to the present invention was devised in view of the above points, and the upper end of the solar heat collecting panel containing the wood pipes is connected to the water storage tank by a connecting rod, and the upper end of the solar heat collecting panel containing the wood pipes is connected to the water storage tank by a connecting rod, and This structure is characterized by housing a tube for communicating between the water storage tank and the wood pipes in the heat collection panel.

The present invention will be explained below with reference to the drawings.

FIGS. 1 and 2 show a top view and a side view of the heat collecting device according to the present invention, and FIG. 3 shows III-II in FIG.
A cross-sectional view is shown in each case.

In FIGS. 1 to 3, reference numeral 1 designates a cylindrical water storage tank made of plastic, and protrusions 2a and 2b are provided on both ends thereof.

Holes 21 are provided through these protrusions 2a and 2b.

3 is a heat collecting panel, and a flat case 3 has a transparent top lid.
It has a structure in which the woodwinds are housed inside.

As shown in FIG. 4, this woodwind includes a vertical main metal pipe 41 attached to a metal plate 40. It is possible to use upper and lower horizontal main metal pipes 42, 43 and vertical metal pipe groups 44, 44 attached by welding.

5a and 5b are connecting rods.

These connecting rods are used to connect the tank and the heat collection panel, but their respective connecting structures are the same, and in the following, only the connecting structure of the connecting rod 5a is shown.

The connecting rod 5a is hollow, and has mouth pipes 51 at both ends.
, 52 are provided, and a tube 6 is housed inside.

The mouth pipes 51 at the upper ends of these connecting rods 5a are screwed to the perforated protrusions 2a on one end surface of the water storage tank 1, and the tubes 6
is drawn into the water storage tank 1.

The mouth pipe 52 at the lower end of the connecting rod 5a is inserted into the mouth pipe 32a provided on the upper end side of the case 31 of the heat collecting panel 3, and is inserted into the mouth pipe 32a provided at the upper end side of the case 31 of the heat collecting panel 3.
10 is inserted and connected to the tube 6 in the connecting rod 5a.

FIG. 5 shows this plug-in connection configuration, and 7 is a rubber ring.

53 is a collar provided on the mouth pipe 52 at the lower end of the connecting rod 5a;
7 connects this collar 53 to the mouth pipe 32 on the upper end side of the heat collecting panel 3.
A is a cap nut to be tied to a, and 8 is a connecting rod 5a and a tube 6.
This is an insulating material filled between the

In the above, when the water in the metal pipe of the heat collection panel is heated to a certain temperature by solar heat, the valve of the upper horizontal main pipe is opened, and the water level pressure in the water storage tank causes the water inside the metal pipe of the heat collection panel to be heated to a certain temperature. of water is forced out.

The solar heat collection device according to the present invention has the configuration as described above, and a tube that connects the water storage tank and the heat collection panel is housed in a mechanically strong connecting rod that connects the water storage tank and the heat collection panel. Therefore, the tube is mechanically protected by the connecting rod and is well insulated.

Therefore, mechanical damage to the tube and tube breakage due to freezing within the tube can be effectively prevented.
