Abstract
The utility model relates to a solar energy technology, and discloses a solar energy photovoltaic device which comprises a photovoltaic panel; the lower part of the photovoltaic panel is provided with an aluminium base plate; an insulation heat conduction layer is arranged between the photovoltaic panel and the aluminium base plate; the bottom surface of the aluminium base plate is provided with a circuit board layer; the heat generated by the direct radiation of sunlight for the photovoltaic panel is accumulated and then is transmitted to the aluminium base plate by the insulation heat conduction layer, and the heat generated by energy consumption of electronic components in the circuit board layer is also diffused by the aluminium base plate; and due to high coefficient of heat conductivity of the aluminium base plate, the heat dispersion performance of the photovoltaic panel and the circuit board layer is greatly improved, and the work stability of the circuit board layer is improved.
Description
Technical field
The utility model relates to heliotechnics, particularly a kind of photovoltaic device.
Background technology
Solar energy is green energy resource, and photovoltaic panel is the Important Components that converts solar energy into electrical energy.But at the big-power solar photo-voltaic power generation station, sunlight can't effectively derive and eliminate the heat energy that photovoltaic panel produces, thereby causes affecting the stability of its normal operation and the life-span of circuit board original paper at the PCB at photovoltaic panel back side circuit board excess Temperature.
In addition, in the big-power solar power station, the heat that the electronic devices and components power consumption self produces in the heat history that sunlight produces the photovoltaic panel direct irradiation and the photovoltaic panel back side circuit board mainly adopts fan or water-cooling method, and its cost is higher, and poor stability.
Summary of the invention
The purpose of this utility model is to provide a kind of photovoltaic device, can significantly increase the heat dispersion of photovoltaic panel and circuit board, improves the stability of circuit board work.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of photovoltaic device is characterized in that, comprises photovoltaic panel, and the photovoltaic panel bottom is provided with aluminium base, is provided with thermal insulation layer between photovoltaic panel and the aluminium base, and the bottom surface of aluminium base has board layer.
Characteristics of the present utility model and further the improvement are:
Described photovoltaic panel, thermal insulation layer, aluminium base are hot-forming structure once.
The contact-making surface of described thermal insulation layer scribbles heat-conducting silicone grease.
Described thermal insulation layer, photovoltaic panel embed the upper surface of aluminium base successively.
Photovoltaic device of the present utility model, comprise photovoltaic panel, the photovoltaic panel bottom is provided with aluminium base, be provided with thermal insulation layer between photovoltaic panel and the aluminium base, the bottom surface of aluminium base has board layer, and sunlight passes to aluminium base to the heat history that the photovoltaic panel direct irradiation produces by thermal insulation layer, and the heat that the electronic devices and components power consumption self produces in the board layer also dispels the heat by aluminium base, thereby, improve the stability of board layer work.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a photovoltaic device of the present utility model;
Among the figure: 1, photovoltaic panel; 2, thermal insulation layer; 3, aluminium base; 4, board layer.
Embodiment
With reference to Fig. 1, be a kind of photovoltaic device of the present utility model.Wherein, photovoltaic panel 1 bottom is provided with aluminium base 3, is provided with thermal insulation layer 2 between photovoltaic panel 1 and the aluminium base 3, and the material of thermal insulation layer 2 is polytetrafluoroethylene film, and the lower plane of aluminium base 3 has board layer 4.Photovoltaic panel 1, thermal insulation layer 2, aluminium base 3 are hot-forming structure once, and thermal insulation layer 2, photovoltaic panel 1 embed the upper surface of aluminium base 3 successively, and the contact-making surface of thermal insulation layer 2 scribbles heat-conducting silicone grease.
When this photovoltaic device uses, sunlight passes to aluminium base 3 to the heat history that photovoltaic panel 1 direct irradiation produces by thermal insulation layer 2, the heat that the electronic devices and components power consumption self produces in the board layer 4 also dispels the heat by aluminium base 3, the conventional PCB that uses is the circuit board of substrate, its conductive coefficient is 0.15-0.25W/m ℃, and the conductive coefficient of aluminium base is 50-60W/m ℃, both conductive coefficients differ more than 300 times, so adopt aluminium base can significantly increase the heat dispersion of photovoltaic panel and board layer, thereby improve the stability of board layer 4 work, especially be suitable in the high power station.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
