Description

Solar panel with optical concentration of sandwich design

Technical field

Obtaining thermal energy from a solar source.

BACKGROUND OF THE INVENTION

Several design solutions for solar panels are currently being used that use solar energy to obtain thermal energy. Although the current design attempts to prevent energy leakage into the environment through the various insulation of individual parts of the solar panels, it is precisely through the front of the panel that is irradiated by the sun's rays that a large percentage of the energy recovered escapes into the surrounding space. This drawback was attempted to eliminate the solar panel with optical concentration and transmission bodies (utility model CZ 19748). His design was conceived as a self-supporting device of a classical compact body. In the implementation according to this design, it has been found that such an embodiment does not suit large-scale solar panels of approximately 1 m x 2 m, since the panel bodies of the heat-insulating material bend and must be built into the supporting frames. Problems are also caused by impurities coming from the surroundings to the exposed optical lenses.

The essence of the technical solution

The newly designed solution consists in creating the construction of the panel on the principle of sandwich arrangement in the following layers:

- A layer of transparent material covering the lenses in their carrier.

- Reinforcing steel sheet.

- Convex optical lens carrier.

- Panel body made of insulating material, which gills as much as possible the heat loss of the obtained thermal energy with the transmission bodies with high thermal conductivity for the transfer of thermal energy. In the transfer of thermal energy, there is minimal loss to the surroundings of the solar panel, i

- Bottom reinforcing steel sheet.

The sandwich panel thus arranged exhibits high rigidity even with larger dimensions.

To increase strength, cylindrical placement of the transmission bodies so that the bodies touch the bottom of the panel body and are adhered to the bottom helps. Moreover, the heat transfer is more favorable due to the flow of liquid over the respective cylindrical surface of the transmission body, which is thus simpler to manufacture than the original transmission bodies with a flat shoulder shaft.

The problems associated with manufacturing inaccuracies and the inability to focus each lens as needed are eliminated by placing the lenses in their carrier so that the optical lenses are seated in their carrier in a spherical cavity that allows them to rotate each optical lens so that a concentrated beam of sunlight fell exactly on the portable body. The newly designed sandwich-type solar panel structure with an optical concentration of sunlight is original compared to conventional solar panels where the liquid is routed in a duct within an enclosed space and utilizes a greenhouse effect or simple panel panels.

Example of technical solution

The cylindrical-shaped transfer bodies 6 of highly thermally conductive material are firmly inserted into the panel body 5 of the thermally insulating material. Above the upper part of the thermal insulating panel body 5 there is an optical assembly carrier 3 having an array of convex optical lenses 4 spaced therefrom from the upper surface of the thermal insulating panel body 5 such as equal to the focal length of the convex optical assembly used. 4. The circulating medium 8 flows through the interior of the thermally insulating panel body 5 and bypasses the cylindrical-shaped transfer bodies 6 of highly thermally conductive material adhered by the bottom surface to the bottom of the thermally insulating panel body 5 to receive thermal energy. The convex optical lenses 4 are embedded in spherical cavities in a spherical shape in the carrier 3 of the optical system.
