Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] The core of the present application is to provide an air-cooled heat dissipation system, which can drive the shaft wheel by airflow to further drive the heat dissipation piece to rotate, thereby improving the air flow rate on the surface of the photovoltaic module, improving the heat dissipation efficiency, and ensuring the power generation efficiency of the photovoltaic module. Another core of the present application is to provide a photovoltaic system comprising the above-mentioned air-cooled heat dissipation system.

[0038] The air-cooled heat dissipation system provided by the present application comprises an air supply device 1, a gas conveying pipeline 5, a shaft wheel 6 and a heat dissipation piece 4. Please refer to Figure 1 , Figure 2 .

[0039] The air supply device 1 can provide airflow, which can be a blower, an electric air pushing device, a fan, a compressor or other devices capable of providing airflow at a certain speed or high pressure.

[0040] If the air supply device 1 is a blower, the outlet of the blower is connected to the gas conveying pipeline 5, so that high-speed airflow can be introduced into the gas conveying pipeline 5 to drive the shaft wheel 6. If the air supply device 1 is a compressor, the airflow can be pressurized and sent into the gas conveying pipeline 5 to provide high-pressure airflow to drive the shaft wheel 6. The above-mentioned mode is only an example and does not limit the specific type of the air supply device 1. As long as it can provide stable airflow.

[0041] In this application, please refer to Figure 5 The air-cooled heat dissipation system is used for heat dissipation of the photovoltaic module 13. If the air supply device 1 is a blower, the number of blowers and the gas conveying pipelines 5 connected thereto can be increased adaptively according to the volume and model of the photovoltaic module 13. The model of the blower, the shape and length of the gas conveying pipeline 5, etc. can also be changed adaptively according to the volume and model of the photovoltaic module 13, so as to ensure full coverage of the photovoltaic module 13 and ensure the heat dissipation effect.

[0042] In an embodiment, the inner side of the air conveying pipeline 5 is provided with an axle wheel 6, and the airflow provided by the air supply device 1 to the air conveying pipeline 5 can drive the rotation of the axle wheel 6, specifically, the airflow can drive the rotation of the axle wheel 6. Specifically, the axle wheel 6 can be at least one, that is, one, two, three or more.

[0043] The heat dissipation member 4 is arranged on the outer side of the air conveying pipeline 5 and is connected to the axle wheel 6. Here, the outer side is relative to the inner side of the air conveying pipeline 5. One end of the air conveying pipeline 5 is connected to the air supply device 1 to obtain the airflow, and the other end is used to communicate with the atmosphere. The air supply device 1 continuously provides the airflow to the air conveying pipeline 5, so as to continuously drive the rotation of the axle wheel 6, that is, to continuously rotate the heat dissipation member 4. After the heat dissipation operation is completed, the air supply device 1 is closed.

[0044] Here, the end of the heat dissipation operation corresponds to the surface temperature of the photovoltaic module 13 being reduced to a reasonable range, and the heat dissipation operation does not need to be continued. Specifically, the temperature of the surface of the photovoltaic module 13 can be obtained by a temperature detection element.

[0045] In the embodiment, the heat dissipation member 4 is located on the outer side of the air conveying pipeline 5 and on the lower side of the photovoltaic module 13. When the photovoltaic module 13 operates at a high temperature, the rotation of the heat dissipation member 4 can accelerate the airflow, so as to ensure the reliable heat dissipation effect of the photovoltaic module 13.

[0047] In an embodiment, one axle wheel 6 corresponds to three heat dissipation members 4. The three heat dissipation members 4 are arranged along the surface of the photovoltaic module 13. When the axle wheel 6 rotates under the action of the airflow, the three heat dissipation members 4 can rotate synchronously, so as to blow the air at different positions on the surface of the photovoltaic module 13, to accelerate the airflow rate and improve the heat dissipation efficiency of the photovoltaic module 13.

[0048] If two heat dissipation members 4 are arranged, the two heat dissipation members 4 can be arranged on both sides of the axle wheel 6 to ensure the balance and stability. When the axle wheel 6 rotates under the action of the airflow, the two heat dissipation members 4 can rotate synchronously, so as to blow the air at different positions on the surface of the photovoltaic module 13, to accelerate the airflow rate and improve the heat dissipation efficiency of the photovoltaic module 13.

[0050] In the embodiment, the gas pipeline 5 can be straight, U-shaped, serpentine, or the like, and can be flexibly designed according to the size of the photovoltaic module 13.

[0051] In the embodiment, the airflow provided by the air supply device 1 to the gas pipeline 5 can drive the rotation of the shaft wheel 6 located in the gas pipeline 5, and further drive the rotation of the heat dissipation member 4 located outside the gas pipeline 5 through the shaft wheel 6. The rotation of the heat dissipation member 4 can drive the airflow on the surface of the photovoltaic module 13, so as to improve the airflow rate and the heat dissipation efficiency of the photovoltaic module 13.

[0052] Based on the above embodiment, please refer to Figure 3 The shaft wheel 6 includes a body 61 and a rotating blade 62 connected to the body 61. When the airflow flows into the gas pipeline 5, the rotating blade 62 can rotate to realize the rotation of the body 61. The rotating blade 62 can have a spiral shape or an arc surface structure or other forms, which can facilitate the airflow and be easily driven, so as to ensure the reliability of the rotation of the shaft wheel 6 as a whole when the high-speed or high-pressure airflow passes through the rotating blade 62.

[0053] As shown in Figure 3 The two rotating blades 62 are connected to the two sides of the body 61, and the rotation direction of the rotating blade 62 is toward the direction of the airflow, so as to ensure the reliability and stability of the driving of the heat dissipation member 4.

[0054] It should be noted that the rotation of the rotating blade 62 is related to the speed and airflow of the airflow provided by the air supply device 1, and the type, model, and power of the air supply device 1 can be selected according to different use scenarios or operation requirements.

[0055] The body 61 is connected to at least one heat dissipation member 4 through the output shaft 10. The airflow in the gas pipeline 5 can drive the rotating blade 62 to rotate the body 61 and the heat dissipation member 4. The rotation of the heat dissipation member 4 can drive the airflow on the surface of the photovoltaic module 13, so as to improve the airflow rate and the heat dissipation efficiency.

[0056] In the embodiment, the connection between the output shaft 10 and the body 61 can be achieved by a shaft sleeve, a shaft coupling, or the like, or the output shaft 10 and the body 61 can be integrated, which can be selected or designed according to actual operation requirements.

[0057] In the embodiment, the output shaft 10 can be located outside the gas pipeline 5, and the body 61 is connected to the output shaft 10 near the gas pipeline 5. The output shaft 10 can also be partially located in the gas pipeline 5 to connect the body 61, and partially located outside the gas pipeline 5 to connect the heat dissipation member 4.

[0058] On the basis of any of the above embodiments, the connection between the output shaft 10 and the gas conveying pipeline 5, and the connection between the air supply device 1 and the gas conveying pipeline 5 are both provided with a sealing member.

[0059] In order to ensure that the gas flow in the gas conveying pipeline 5 can flow to the shaft wheel 6 in sufficient amount, and to ensure the reliable driving of the gas flow to the shaft wheel 6, a sealing member is arranged at the connection between the air supply device 1 and the gas conveying pipeline 5, which is a static seal, and a sealing ring can be arranged at the outlet of the air supply device 1 to ensure the sealing effect; a sealing member is arranged at the connection between the output shaft 10 and the gas conveying pipeline 5, which can be arranged in the mounting hole of the output shaft 10 on the outer wall of the gas conveying pipeline 5, or can be arranged on the outer periphery of the output shaft 10, as long as the sealing effect can be ensured.

[0060] In the present embodiment, the number and shape of the sealing member are not limited, and can be set according to the actual operation situation and use requirements.

[0061] On the basis of any of the above embodiments, please refer to Figure 2 , Figure 5 , the gas conveying pipeline 5 is provided with a plurality of shaft wheels 6 arranged along the gas conveying path direction, and the gas conveying path is used to correspond to the transverse and / or longitudinal direction of the surface of the photovoltaic module 13.

[0062] In one embodiment, as shown in Figure 6 , the gas conveying pipeline 5 is in a U-shaped structure, and a plurality of shaft wheels 6 are arranged on both sides of the U-shaped structure. After the air supply device 1 introduces the gas flow into the gas conveying pipeline 5, the shaft wheels 6 on both sides can rotate, so that the plurality of heat dissipation members 4 connected to the shaft wheels 6 on both sides can rotate, so as to accelerate the gas flow on the longitudinal / transverse position of the surface of the photovoltaic module 13, and to ensure the heat dissipation effect of the photovoltaic module 13.

[0063] Among them, the bottom part of the U-shaped structure is not provided with a shaft wheel 6, which can facilitate the smooth flow of the gas flow along the gas conveying path from one side of the U-shaped structure to the other side, and ensure the reliable driving of the gas flow to the plurality of shaft wheels 6 on both sides.

[0064] In another embodiment, the gas conveying pipeline 5 can be arranged in the form of a cross structure, such as a cross shape, and a shaft wheel 6 can be arranged around the cross structure, so as to improve the coverage range of the heat dissipation member 4 connected to the shaft wheel 6, and to ensure the reliable heat dissipation of the photovoltaic module 13 in all directions on the surface of the photovoltaic module 13.

[0065] In the present embodiment, the transverse and longitudinal directions of the surface of the photovoltaic module 13 are only defined as the directions of the photovoltaic module 13 as a conventional cuboid structure, and are not limited to the shape of the gas conveying pipeline 5 of the present application.

[0066] On the basis of any of the above embodiments, please refer toFigure 3 The fixed plate 9 is connected with the supporting member 8, and the supporting member 8 is rotationally connected with the body 61 to form support for the shaft wheel 6.

[0067] In the embodiment, the fixed plate 9 can be detachably connected with the inner wall of the gas conveying pipeline 5, or can be welded to the inner wall of the gas conveying pipeline 5. It should be noted that, if the fixed plate 9 is detachably connected with the gas conveying pipeline 5, sealing measures need to be taken between the two to avoid gas leakage affecting the rotation effect of the shaft wheel 6; or the fixed plate 9 and the inner wall of the gas conveying pipeline 5 are connected by fasteners, but the fasteners do not penetrate the gas conveying pipeline 5, that is, no through holes are generated, and the leakage of gas at the connection can also be avoided.

[0068] In the embodiment, the supporting member 8 is specifically used to support the shaft wheel 6 in cooperation with the fixed plate 9. The supporting member 8 is fixed to the fixed plate 9, but the shaft wheel 6 can rotate relative to the supporting member 8. The rotational connection between the shaft wheel 6 and the supporting member 8 can be achieved by means of a shaft sleeve, a bearing or the like to ensure the reliable stability of the shaft wheel 6 during rotation.

[0069] On the basis of any of the above embodiments, please refer to Figure 2 , Figure 5 In the direction of the gas conveying path of the gas conveying pipeline 5, the front end of any shaft wheel 6 is provided with an inclined plate 7. One end of the inclined plate 7 is connected to the top or bottom of the inner wall of the gas conveying pipeline 5, and the other end of the inclined plate 7 is inclined towards the shaft wheel 6.

[0070] The inclined plate 7 can specifically provide a certain guiding effect while locally reducing the size of the pipe opening of the gas conveying pipeline 5 to compress the space and form a wind power "gorge" to increase the flow pressure of the gas flow, so that the gas flow can drive the shaft wheel 6 to rotate with greater power to ensure the reliable rotation effect of the shaft wheel 6.

[0072] In the embodiment, if the gas conveying pipeline 5 is a square structure, the two side portions of the square structure are used to connect with the side portions of the inclined plate 7 to ensure that the gas flow can only flow to the shaft wheel 6 from the smaller space formed by the inclined surface and the top / bottom of the square structure to effectively increase the pressure of the gas flow.

[0073] In the embodiment, the front end of any shaft wheel 6 is provided with an inclined plate 7, and the corresponding airflow is first lifted in pressure before passing each shaft wheel 6, thereby ensuring reliable driving of the shaft wheel 6. The angle of each inclined plate 7 can be consistent or inconsistent, for example, showing an increasing trend. If the local place needs to be highlighted for heat dissipation, the angle of the corresponding inclined plate 7 is larger, which can specifically increase the airflow pressure in the local part of the gas conveying pipeline 5, and increase the rotating speed of the corresponding heat dissipation member 4 to ensure the heat dissipation effect of the local place for heat dissipation.

[0074] In the embodiment, the inclined plate 7 can be first welded in the channel steel, and then the plate is welded on the channel steel to form the gas conveying pipeline 5 with an internal hollow after all the inclined plates 7 are welded. Of course, other processing methods can also be used, and no more limitations are made.

[0075] In the embodiment, the end of the inclined plate 7 inclined towards the shaft wheel 6 is arranged not to exceed the axis of the shaft wheel 6, thereby ensuring that the airflow can fully flow to the surface of the shaft wheel 6 and ensuring reliable driving of the shaft wheel 6.

[0076] On the basis of any of the above embodiments, please refer to Figure 2 The angle between the surface of the inclined plate 7 and the plane where the top or bottom of the inner wall of the gas conveying pipeline 5 is located is 30°-45°.
