Description
Technical Field
The invention relates to the field of new energy, in particular to a point-to-point condensation system of a solar light collector.
Background
Conventional photovoltaic panels are directly exposed to the external environment, and generate electric energy by direct irradiation of sunlight. However, the power generation efficiency of the method is affected by weather, environment, even different time within a day, and other factors, and in addition, the method is directly exposed to the air, so that a large amount of dust is accumulated on the surface, and the power generation efficiency is low. Therefore, the solar light collector is developed and applied in a large amount at present, and a large amount of sunlight is collected and irradiated on the photovoltaic panel in a concentrated manner, so that the power generation efficiency and the service life of the photovoltaic panel can be greatly improved.
However, due to the application of the focusing optical element, the local temperature of the solar collector is increased sharply, which is not only a challenge for the lifetime of the device, but even causes a fire disaster in severe cases. Therefore, the solar collector is subjected to local cooling, and a key technology is formed.
Disclosure of Invention
In order to solve the technical problems, the invention provides a point-to-point condensation system of a solar light collector.
The technical scheme provided by the invention is as follows:
the point-to-point condensing system of the solar energy light collector comprises a focusing lens array, a grating cavity array and a mirror surface chassis, wherein an arc-shaped corner mirror surface is arranged at the lower side of a gap of the grating cavity array, and a nucleating film piece, an absorption core, a radiating fin, a supporting spring, a cavity upper cover, a substrate, a hollow conduit and a steam cavity around the hollow conduit are arranged in the grating cavity array; the nucleating film piece is of a double-concave mirror structure, one surface of the nucleating film piece is tightly attached to the inner side of the corner mirror surface, and the other surface of the nucleating film piece is tightly attached to the surface of the absorption core; one surface of the radiating fin is connected with a supporting spring fixed on the substrate, and the other surface of the radiating fin is attached to the absorption core, so that heat energy of the absorption core is volatilized and the absorption core is fixed. A plurality of hollow conduits penetrate through the grating cavity array.
The focusing lens array concentrates sunlight at the gap of the grating cavity array, part of light passes through the gap, and part of light is concentrated on the corner mirror surface, so that the local temperature is increased. A condensing system located inside the grating cavity array will transfer this part of the thermal energy out. The structure can solve the problem of overhigh local temperature of the device caused by the focusing optical element, prolongs the service life of the device, and ensures normal and safe use of the device.
Further, all openings of the hollow conduits are arranged on the outer side of the light collector, so that air can flow directly.
Furthermore, the nucleated film material is copper or aluminum or other metal which is extremely easy to conduct heat.
Further, the side surfaces of the absorbent core are designed to be oval.
Further, the material of the absorption core is a compound ceramic material doped with aluminum nitride, aluminum oxide, nickel or copper, and the main purpose is to quickly absorb and volatilize heat from the corner mirror surface.
Further, the hollow conduit is a non-closed tube made of copper or aluminum.
The condensation principle is as follows:
under the action of the focusing lens, part of sunlight is converged on the corner mirror surface, and the local temperature can be increased. The nucleated film elements located inside the vapor chamber rapidly transfer thermal energy into the absorbent core and onto the heat sink. Due to the relatively large area of the absorbent core and the heat sink, the air inside the vapor chamber can be heated quickly. Because the cavity is internally provided with a plurality of copper or aluminum hollow conduits and communicated with the outside air, the heat in the steam cavity can be dissipated along with the reasons of air convection of the hollow conduits, metal heat conduction and the like, thereby achieving the purpose of cooling.
Compared with the prior art, the invention has the remarkable advantages that:
1. the hollow conduit of the invention is directly communicated with the outside, and the design structure does not need any external energy to be connected, thereby greatly improving the power generation efficiency and the applicable environment of the equipment.
2. The invention adopts the double-concave surface nucleated film structure, and can transfer heat energy of the corner mirror surface higher.
3. The invention adopts the structure of the spring and the radiating fin, not only can fix the absorption core and quicken the radiation, but also is very convenient for the device assembly, does not need more and more complicated operations in a narrow space, and is simple and effective.

Detailed Description
The invention will be further illustrated with reference to specific examples.
The point-to-point condensing system of the solar energy collector comprises a focusing lens array 1, a grating cavity array 2 and a mirror surface chassis 3, wherein an arc-shaped corner mirror surface 20 is arranged on the lower side of a gap of the grating cavity array 2.
As shown in fig. 2, the grating cavity array 2 is internally provided with a nucleating film 21, an absorption core 22, a heat sink 23, a supporting spring 24, a cavity upper cover 26, a base 27, a hollow conduit 28 and a steam cavity 25 around the hollow conduit 28; the nucleating film piece 21 is of a biconcave mirror structure, one surface of the nucleating film piece is tightly attached to the inner side of the corner mirror surface 20, and the other surface of the nucleating film piece is tightly attached to the surface of the absorption core 22; the heat sink 23 is connected to the support springs 24 fixed to the base 27 on one side and is attached to the absorbent core 22 on the other side.
A plurality of hollow conduits 28 pass through the grating cavity array 2. The focusing lens array 1 concentrates sunlight at the gaps of the grating cavity array 2, part of the light passes through the gaps, and part of the light is concentrated on the corner mirror surface 20, so that the local temperature is increased. All the openings of the hollow conduits 28 are outside the collector, facilitating the direct circulation of air, as shown in fig. 3.
The nucleating film 21 is made of copper or aluminum or other metal which is extremely easy to conduct heat. The side of the absorbent core 22 is designed in an oval shape. The material of the absorbent core 22 is a composite ceramic material doped with aluminum nitride, aluminum oxide, nickel or copper, which rapidly absorbs and volatilizes heat from the corner mirrors. The hollow conduit 28 is a non-closed tube made of copper or aluminum.
Under the action of the focusing lens, part of the sunlight is concentrated on the corner mirror surface 20, and the local temperature is raised. The nucleated film located inside the vapor chamber 25 will rapidly transfer thermal energy into the absorbent core 22 and onto the heat sink 23. Due to the relatively large area of the absorbent core 22 and the heat sink 23, the air inside the steam chamber 25 can be heated quickly. Because the steam cavity 25 is internally provided with the copper or aluminum hollow guide pipes 28 and is communicated with the outside air, the heat in the steam cavity 25 can be dissipated along with the reasons of air convection of the hollow guide pipes 28, metal heat conduction and the like, thereby achieving the purpose of cooling.
The present invention is not limited to the preferred embodiments, and any simple modification, equivalent replacement, and improvement made to the above embodiments by those skilled in the art without departing from the technical scope of the present invention, will fall within the scope of the present invention.
