Abstract

PURPOSE:To enhance thermal energy utilizing efficiency, and an efficiency in converting thermal energy into electrical energy, by a method wherein a space between light-transmitting outer and inner pipes is used as a vacuum heat- insulating layer, while a substantially atmospheric gas layer is provided inside the inner pipe, a heat-collecting part is provided in the gas layer, and a solar cell is fitted in the heat-collecting part. CONSTITUTION:The space between the light-transmitting outer pipe 1 and the light-transmitting inner pipe 3 is maintained in a vacuum condition to constitute the heat-insulating layer 4. A heat-transmitting medium pipe 5 is supported at the center of the inner pipe 3 by a support 6 and an end plate 7. The pipe 5 has a double-pipe construction consisting of an inner pipe 5a and an outer pipe 5b. A flat plate form heat-collecting plate 9 is fitted above the pipe 5, and the solar cell 10 is provided above the plate 9. The energy of the solar cell 10 is taken out through a lead 10a and an electrode 10b. The interior of the inner pipe 3 is set at a gas pressure approximate to the atmospheric pressure. Since the heat absorbed by the solar cell 10 is released into the heat-collecting plate 9, the temperature of the cell itself can be prevented from rising.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a solar heating system in which a heat collector S for absorbing water heat energy is enclosed in a translucent glass tube, and a solar cell is attached to the heat collector part. It is designed to convert energy into thermal energy 2 and electrical energy.

A solar heating system that converts solar energy into direct vapor energy and a solar heating system that converts solar energy into thermal energy have already been independently developed. The power generation efficiency of this Sugi solar cell is at most 10%ii&,
When a solar cell receives solar radiation, part of it is reflected from the TM steel, but most of the rest is emitted as thermal energy. The power generation efficiency of a solar cell is greatly influenced by the ambient temperature in the usage state, and if the solar cell is exposed to high temperatures, the output becomes unstable and the efficiency decreases. Therefore, it is preferable to reduce the temperature rise of the solar cells as much as possible. The present invention has been made in consideration of the above points, and converts solar energy into electrical energy using solar cells. The purpose is to effectively utilize the heat absorbed by solar cells, and this purpose is based on the original F! According to 4, a gas layer with a pressure approximately equal to atmospheric pressure is formed in a vacuum-insulated translucent tube with a dual structure inside and outside, and a heat collecting S is formed to absorb heat by depositing solar cells in this gas layer. This is achieved by storing.

Examples of the present invention will be described below based on the wJ plane. J

A translucent inner tube 3 made of glass or the like bonded to the inner tube 3 is provided, and the space between the outer tube 1 and the inner tube 3 forms a heat insulating layer 4 layered with a vacuum cliff. The part indicated by 1m is the empty sealed part. A heat medium pipe 5 is installed at the axial center of the inner f3 ξ7
One end of this heat medium pipe 5 is connected to a heat medium telegram 6.

The other end is supported by an end plate 7. As is clear from FIG. 2, the JIlII pipe 5 consists of an inner pipe 5a and an outer pipe 5b. A gas layer 11 close to atmospheric pressure is formed inside the inner tube 3. The salt mountain in which this gas layer 11 is provided is expected to have a heat insulating property similar to that of the heat insulating layer 4 described above. This is provided in order to simplify the structure by eliminating segregation that passes through 7 and a portion where an electrode 10b (to be described later) passes through end fj7.

A flat system heating plate 9 is attached to the outer periphery of the heat medium pipe 5 in an S conductive manner to constitute a solar heating system heating section. The solar cell 10 is arranged on a flat plate-shaped portion of the system heating plate 9. The solar cell mlo can be singular or compound.

The electrical energy of the solar cell is led out to the outside via the beam mlom by the end 1j76c*girder electrode 10b supporting the heat medium tube sf.

The heat collected on the solar panel ak is transferred to the heat medium pipe 5 via the heat collecting plate 9. The heat transferred to the heat medium pipe 5 is transferred from the outer pipe 5b of the heat medium pipe 5 to the inner pipe sa. #cfIL is absorbed by the heating medium P, so that the temperature rise of the solar cell 1o can be suppressed, and furthermore, the energy can be used more effectively by the heating medium P.

It is configured as follows. In the case of what is shown in Figure 3, the installation of a solar heating system becomes a burden.

According to the present invention described above, sunlight that enters through the vacuum insulation layer formed at the threshold between the transparent outer tube and the transparent inner tube is absorbed by the solar cells provided in the transparent inner tube.

It can increase the efficiency of thermal energy accumulation.

2) Heat can be used effectively by integrating a thick m battery and a solar S& system heater.

3) Since the heat generated in the solar cell can be suppressed by the heat medium, the temperature rise of the solar cell can be suppressed to a low level, and the conversion efficiency into -air energy can be increased.
