[0002] A concealed energy power generation equipment refers to a power generation equipment that can perform infrared shielding function, reducing the risk of the equipment being detected. It is usually used in scenarios with strict concealment requirements such as military and aerospace, taking into account power generation efficiency and environmental adaptability. This type of power generation equipment mainly uses solar energy for power generation, such as solar panels. Since traditional solar panels mainly absorb visible light, while infrared rays are reflected by the solar panels, and the reflected infrared rays have high heat energy and are easily detected. Therefore, this application proposes a concealed energy power generation equipment. Content of the Utility Model

[0003] In view of the above situation, to overcome the defects of the prior art, the utility model provides a concealed energy power generation equipment, effectively solving the problem that the existing solar power generation equipment is prone to reflect infrared rays and cause poor concealment.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A concealed energy power generation equipment, including a support frame and a plurality of photovoltaic power generation board units. The photovoltaic power generation board units are connected inside the support frame. The photovoltaic power generation board unit is composed of an aluminum alloy square frame, an energy absorption and heat dissipation layer, a TPT backplane, an EVA layer 1, battery cells, an EVA layer 2, and a double-layer vacuum high-transparency glass layer. The energy absorption and heat dissipation layer is connected to the bottom end of the TPT backplane, the EVA layer 1 is connected to the top end of the TPT backplane, the battery cells are connected to the top end of the EVA layer 1, the EVA layer 2 is connected to the top end of the battery cells, and the double-layer vacuum high-transparency glass layer is connected to the top end of the EVA layer 2;

[0005] An indium tin oxide coating is provided on the top surface of the double-layer vacuum high-transparency glass layer, and a cesium-doped tungsten oxide coating is provided on the bottom surface of the double-layer vacuum high-transparency glass layer;

[0006] The energy absorption and heat dissipation layer is composed of a graphene heat conduction layer, an aluminum heat dissipation plate, and a plurality of aluminum heat dissipation fins. The aluminum heat dissipation plate is located at the bottom surface of the graphene heat conduction layer, and the aluminum heat dissipation fins are welded to the bottom end of the aluminum heat dissipation plate.

[0007] Preferably, the double-layer vacuum high-transparency glass layer is composed of a first high-transparency glass plate and a second high-transparency glass plate, and a vacuum chamber is formed between the first high-transparency glass plate and the second high-transparency glass plate.

[0008] Preferably, the edge of the connection between the first high-transparency glass plate and the second high-transparency glass plate is hermetically sealed at high temperature by indium tin alloy solder, and a silicone rubber sealing strip is provided on the outer side wall of the connection between the first high-transparency glass plate and the second high-transparency glass plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

By providing a cesium-doped tungsten oxide coating, the doping of cesium ions changes the electronic structure of tungsten oxide, which has strong absorption characteristics in the near-infrared band (780 - 2500 nm), while maintaining a high light transmittance (>70%) in the visible light region.

[0023] As given by Figures 1 to 4 A stealth power generation device of the present utility model includes a support frame 1 and a plurality of photovoltaic power generation panel units 2. The photovoltaic power generation panel units 2 are connected inside the support frame 1. The photovoltaic power generation panel unit 2 is composed of an aluminum alloy square frame 3, an energy - absorbing and heat - dissipating layer 4, a TPT backplane 5, a first EVA layer 6, a battery cell 7, a second EVA layer 8, and a double - layer vacuum high - light - transmission glass layer 9.

[0024] The aluminum alloy square frame 3 realizes the functions of support and encapsulation. The energy - absorbing and heat - dissipating layer 4 can dissipate heat energy from the back of the photovoltaic panel. The double - layer vacuum high - light - transmission glass layer 9 can reduce heat radiation by using the vacuum heat - insulation effect and improve the stealth performance;

[0025] An indium tin oxide coating 10 is provided on the top surface of the double - layer vacuum high - light - transmission glass layer 9, and a cesium - doped tungsten oxide coating 11 is provided on the bottom surface of the double - layer vacuum high - light - transmission glass layer 9;

[0026] The indium tin oxide coating can reflect infrared rays before they reach the battery cell. Since the indium tin oxide coating has a low infrared absorption rate, the temperature rise on its surface due to light energy is small. Therefore, the reflected infrared rays are very similar to the infrared rays in the light and do not have thermal energy. Thus, heat insulation can be indirectly achieved by blocking infrared radiation. Cesium ion doping changes the electronic structure of tungsten oxide, which has strong absorption characteristics in the near-infrared band (780 - 2500 nm), while maintaining a high light transmittance (>70%) in the visible light region. Its lattice vibration and electron transition can absorb heat in the mid- and far-infrared band (3 - 15 μm), reducing the infrared radiation transmittance and further reducing the thermal radiation of infrared rays, thereby improving the concealment effect;

[0029] The double-layer vacuum high-light-transmittance glass layer 9 is composed of a first high-light-transmittance glass plate 15 and a second high-light-transmittance glass plate 16. A vacuum chamber 17 is formed between the first high-light-transmittance glass plate 15 and the second high-light-transmittance glass plate 16, which can utilize the vacuum effect to improve the heat insulation effect and reduce the thermal radiation;

[0030] The edge of the connection between the first high-light-transmittance glass plate 15 and the second high-light-transmittance glass plate 16 is hermetically sealed by an indium tin alloy solder 18 at high temperature. A silicone rubber seal strip 19 is provided on the outer side wall of the connection between the first high-light-transmittance glass plate 15 and the second high-light-transmittance glass plate 16, which can improve the sealing performance of the connection between the first high-light-transmittance glass plate 15 and the second high-light-transmittance glass plate 16;

[0032] A first heat-conducting silicone grease layer 20 is provided between the graphene heat-conducting layer 12 and the TPT backplane 5, and a second heat-conducting silicone grease layer 21 is provided between the graphene heat-conducting layer 12 and the aluminum heat-dissipating plate 13, which can fill the contact gap and improve the heat conduction and heat dissipation effects.

[0033] During operation, by providing an indium tin oxide coating, infrared rays can be reflected before reaching the cell. Since the indium tin oxide coating has a low infrared absorption rate, the temperature rise on its surface due to light energy is small. Therefore, the reflected infrared rays are very similar to the infrared rays in the light and do not have thermal energy. As a result, heat insulation can be indirectly achieved by blocking infrared radiation. By providing a cesium-doped tungsten oxide coating, the doping of cesium ions changes the electronic structure of tungsten oxide, which has strong absorption characteristics in the near-infrared band (780 - 2500 nm) while maintaining a high light transmittance (>70%) in the visible light region. Its lattice vibration and electron transition can absorb heat in the mid- and far-infrared band (3 - 15 μm), reducing the infrared radiation transmittance and further reducing the occurrence of infrared thermal radiation, thereby improving the concealment effect; by providing a double-layer vacuum high-transparency glass layer composed of a first high-transparency glass plate and a second high-transparency glass plate, heat insulation can be achieved using a vacuum, reducing the possibility of thermal radiation occurring; by providing indium tin alloy solder and silicone rubber sealing strips, the sealing performance between the first high-transparency glass plate and the second high-transparency glass plate can be improved; by providing an energy-absorbing and heat-dissipating layer composed of a graphene heat-conducting layer, an aluminum heat-dissipating plate, and several aluminum heat-dissipating fins, the heat dissipation efficiency of the TPT backplane can be improved, and the thermal energy is dissipated from the back of the photovoltaic panel, thereby reducing the risk of being exposed.
