[0033] In view of the problems of the above related technologies, the present embodiment provides a photovoltaic module and a photovoltaic system.

[0034] As shown in Figure 1 and Figure 2 A photovoltaic module 100 provided by the present embodiment includes a carrier 2, a ventilation structure 1, and a photovoltaic cell 3. The carrier 2 is provided with a first mounting hole 21, the ventilation structure 1 is embedded in the first mounting hole 21, and the photovoltaic cell 3 is arranged around the first mounting hole 21 on the carrier 2.

[0035] Specifically, the diameter of the first mounting hole 21 is greater than or equal to the diameter of the ventilation structure 1, so that the ventilation structure 1 can be smoothly installed in the first mounting hole 21.

[0036] The photovoltaic cell 3 is arranged around the ventilation structure 1, that is, the ventilation structure 1 can be arranged in the area within the four peripheral edges of the photovoltaic cell 3, so that the ventilation structure 1 can be arranged through the carrier 2 and the photovoltaic cell 3.

[0037] The entire photovoltaic module can be directly or indirectly installed on the roof of a building through a photovoltaic support.

[0038] The photovoltaic cell and the carrier can adopt the following two positional relationships. For example, the first kind, combined with Figure 1 If the carrier 2 is arranged above the photovoltaic cell 3, the carrier 2 can protect the photovoltaic cell 3 from the outside, and the carrier can be made of a light-transmitting material, so that sunlight can pass through the carrier 2 and irradiate the photovoltaic cell 3, realizing photovoltaic power generation. The second kind, combined with Figure 2As shown, if the carrier 2 is arranged below the photovoltaic cell 3, the carrier 2 can support the photovoltaic cell 3 from below, realizing the installation of the photovoltaic cell 3 on the carrier 2. The material of the carrier 2 can be transparent glass, and can also be other materials, which are not specifically limited here.

[0039] In the photovoltaic module 100 and photovoltaic system of the present disclosure, the photovoltaic module 100 mainly comprises a carrier 2, a ventilation structure 1 and a photovoltaic cell 3. The ventilation structure 1 can be embedded and installed in the first mounting hole 21 of the carrier 2, and the ventilation structure 1 and the carrier 2 are quickly assembled by the way of opening holes on the carrier 2. The photovoltaic cell 3 can be arranged around the ventilation structure 1 on the carrier 2, and the photovoltaic cell 3 realizes the power generation function. In addition, through the ventilation structure 1 penetrating the carrier 2 and the photovoltaic cell 3, the air flow between the lower and upper parts of the photovoltaic cell 3 is accelerated during the rotation of the ventilation structure 1 to generate air flow turbulence. Under the action of the air flow turbulence, the air flow on the surface of the photovoltaic module is accelerated, and the heat at the bottom of the photovoltaic module is taken away, realizing the high-efficiency heat dissipation of the photovoltaic module.

[0040] Optionally, in combination with Figure 3 As shown, the ventilation structure 1 comprises a base 11 and a cooling device 12. The base 11 is embedded in the first mounting hole 21, and the base 11 is provided with a second mounting hole 111. The cooling device 12 is embedded in the second mounting hole 111.

[0041] Specifically, the size of the first mounting hole 21 is greater than or equal to the size of the base 11, so that the base 11 can be smoothly embedded in the first mounting hole 21. The shape of the first mounting hole 21 matches the shape of the base 11. For example, if the end face of the base 11 is rectangular, the first mounting hole 21 can be a rectangular hole (see Figure 1 As shown). If the end face of the base 11 is circular, the first mounting hole 21 can be a circular hole.

[0042] The size of the second mounting hole 111 is greater than or equal to the size of the cooling device 12. The shape of the second mounting hole 111 matches the shape of the cooling device 12. For example, if the cooling device 12 is a cylindrical structure, the second mounting hole 111 is a circular hole (see Figure 3 As shown).

[0043] The cooling device 12 can adopt a fan structure. The fan can adopt a ventilation fan structure without power supply, that is, it can rely on natural wind to rotate. The fan can also adopt a ventilation fan structure with power supply, that is, the power supply of the fan can be electrically connected with the junction box of the photovoltaic system, so as to supply power to the cooling device 12 by the electric energy generated by the photovoltaic system.

[0044] In the related art, a wind cooling device can be installed below the photovoltaic module to achieve heat dissipation of the photovoltaic module by blowing wind to the photovoltaic module by the wind cooling device. However, for the wind cooling device arranged in a narrow space between the photovoltaic module and the building roof of the photovoltaic module 100, there is a problem of inconvenient maintenance.

[0045] In this optional embodiment, the base 11 can be embeddedly installed in the first mounting hole 21 of the carrier 2, and the wind cooling device 12 can be embeddedly installed in the second mounting hole 111 of the base 11. This not only realizes convenient assembly of the base 11 and the first mounting hole 21 of the carrier 2, and the wind cooling device 12 and the second mounting hole 111 of the base 11, but also enables the worker to remove the wind cooling device 12 from above the photovoltaic module 100 to realize convenient maintenance of the wind cooling device 12 in the narrow space between the photovoltaic module 100 and the building roof when the wind cooling device 12 needs to be repaired later.

[0046] Optionally, in combination with Figure 3 As shown in the figure, the second mounting hole 111 is provided with a first threaded layer 1111, and the outer wall of the wind cooling device 12 is provided with a second threaded layer 121 matched with the first threaded layer 1111, and the second threaded layer 121 of the wind cooling device 12 is adaptively connected with the first threaded layer 1111 of the second mounting hole 111. The second threaded layer 121 and the first threaded layer 1111 are adaptively connected, which means that they are connected by threads.

[0047] Specifically, the first threaded layer 1111 of the second mounting hole 111 matches the second threaded layer 121 of the wind cooling device 12.

[0048] If the first threaded layer 1111 is an internal thread, the second threaded layer 121 is an external thread; if the first threaded layer 1111 is an external thread, the second threaded layer 121 is an internal thread.

[0049] In this optional embodiment, the wind cooling device 12 is threadedly connected with the first threaded layer 1111 of the second mounting hole 111 through the second threaded layer 121, so that the wind cooling device 12 is embeddedly installed in the second mounting hole 111 in a rotating manner. This not only realizes quick disassembly and assembly of the wind cooling device 12 and the second mounting hole 111, but also realizes multi-point distributed force through threaded connection between the two, effectively disperses the vibration load generated by the wind cooling device 12 during operation, and reduces the risk of local stress concentration. Furthermore, the cooperation of the second threaded layer 121 and the first threaded layer 1111 can also automatically correct assembly eccentricity and ensure the coaxiality precision of the wind cooling device 12.

[0050] Optionally, in combination with Figures 4 to 6As shown, the base 11 includes a base body 112 and a sealing structure 113. The sealing structure 113 is provided on the outer periphery of the base body 112, and the edge of the bearing member 2 is sealed to the sealing structure 113.

[0051] Specifically, the base body 112 and the sealing structure 113 can be constructed as an integral structure, which can improve the mechanical strength of the base 11 and extend its service life.

[0052] The base body 112 is provided with a second mounting hole 111 for mounting the air-cooled device 12.

[0053] The sealing structure 113 can be sealed to the carrier 2 in the following way: for example, the sealing structure 113 has a groove 1131 on the part facing the carrier 2. The width of the groove 1131 can be greater than or equal to the thickness of the carrier 2. The edge of the carrier 2 can be inserted into (or embedded in) the groove 1131 of the sealing structure 113.

[0054] Among them, the card slot 1131 along Figure 4 and Figure 6 The dimension along the Z-axis in the coordinate system is the width of the slot 1131, and the bearing 2 is along... Figure 6 The dimension along the Z-axis in the coordinate system is the thickness of the bearing 2.

[0055] If the surface of the base 11 is a rectangular structure, a sealing structure 113 is provided around the outer edge of the base body 112 so that the bearing member 2 is sealed to the sealing structure 113 on the base body 112.

[0056] exist Figure 6 In the middle, base 11 is Figure 6 In the coordinate system, the end opposite to the X-axis is the left end of base 11, and base 11 is... Figure 6 The positive X-axis end in the coordinate system is the right end of base 11.

[0057] A gap is left between the left end of the base 11 and the left-side support member 2 to facilitate the demonstration of… Figure 6 The sealing structure 113 of the base 11 has a groove 1131, and the right end of the base 11 is sealed to the right side of the support member 2, so as to reflect the sealing connection relationship between the edge of the support member 2 and the sealing structure 113 of the base 11.

[0058] Figure 6 The curve with arrows at the base 11 represents the flow direction and path of hot air around the photovoltaic module under the rotation of the ventilation structure 1.

[0059] In the optional embodiment, the edge of the carrier 2 is sealingly connected with the sealing structure 113 at the edge of the base body 112, so as to ensure the sealing connection between the carrier 2 and the base 11, reduce the possibility of external dust entering between the carrier 2 and the photovoltaic cell 3 from the connection between the carrier 2 and the base 11, and accordingly ensure the power generation effect of the photovoltaic module 100, and also reduce the maintenance frequency of the photovoltaic module 100.

[0060] Further, by providing the clamping groove 1131 on the sealing structure 113, the edge of the carrier 2 is embedded in the clamping groove 1131 of the sealing structure 113, so as to realize the quick and sealing connection operation between the edge of the carrier 2 and the base 11.

[0061] Optionally, in combination with Figure 4 As shown, the end face shape of the sealing structure 113 is at least one of a C-shaped structure, a stepped structure, and a pleated structure.

[0062] Specifically, the end face shape of the sealing structure 113 is at least one of a C-shaped structure, a stepped structure, and a pleated structure, which means that the end face shape of the sealing structure 113 is any one of a C-shaped structure, a stepped structure, and a pleated structure, or at least two of a C-shaped structure, a stepped structure, and a pleated structure.

[0063] If the end face shape of the sealing structure 113 is a C-shaped structure, the edge of the sealing structure 113 can be embedded in the opening groove of the C-shaped structure, so as to limit the carrier 2 from above and below by the upper and lower parts of the opening groove of the sealing structure 113, and accordingly improve the assembly stability of the base 11 and the carrier 2. Further, the sealing connection between the sealing structure 113 of the base 11 and the carrier 2 can also provide a sealing and reliable edge support for the photovoltaic cell 3, so that a certain gap is maintained between the carrier 2 and the photovoltaic cell 3, avoiding the hard contact between the carrier 2 and the photovoltaic cell 3, which can cause wear of the photovoltaic cell 3 by the carrier 2, and accordingly prolong the service life of the photovoltaic module.

[0064] If the sealing structure 113 is a stepped structure, the carrier 2 can be placed on a certain step of the sealing structure 113 of the base 11, and carriers 2 of different sizes can be installed on the photovoltaic cell 3, which can improve the assembly flexibility of the carrier 2 and the sealing structure 113.

[0065] If the sealing structure 113 is a pleated structure, the pleated structure can be understood as a wavy structure with concave-convex alternation from top to bottom at the edge of the base body 112. The pleated structure is sealingly connected with the edge of the carrier 2 at different positions in the vertical direction, which can adjust the connection position of the base 11 relative to the carrier 2, and correspondingly realize the adjustment of the height of the ventilation structure 1 in the vertical direction, so that the top end of the ventilation structure 1 can protrude from the upper surface of the carrier 2, or the bottom end of the ventilation structure 1 protrudes from the lower surface of the carrier 2, further improving the assembly flexibility of the ventilation structure 1 relative to the carrier 2.

[0066] Optionally, in combination with Figure 4 and Figure 5 As shown in the figure, the base 11 further comprises a support portion 114, which is arranged at the bottom end of the base body 112, and the support portion 114 is in contact with the support surface.

[0067] Specifically, the support portion 114 can adopt the following structure, for example, the periphery of the bottom end of the base body 112 extends outward to form the support portion 114, in other words, the support portion 114 extends outward along the periphery of the bottom end of the base body 112. Figure 4 The size of the base body 112 along the X-axis direction of the coordinate system is greater than the size of the base body 112 along the Y-axis direction of the coordinate system. Figure 4 The size of the base body 112 along the X-axis direction of the coordinate system is greater than the size of the base body 112 along the Y-axis direction of the coordinate system.

[0068] The support surface can be the position where the photovoltaic module is installed, for example, the support surface refers to the top surface of the building roof.

[0069] In this optional embodiment, when the photovoltaic module 100 is installed on the support surface of the building roof, the support portion 114 at the bottom end of the base body 112 can be in contact with the support surface directly or through a photovoltaic support, so that the ventilation structure 1 is parallel to the support surface through the support portion 114, and the installation work of the ventilation structure 1 relative to the carrier 2 and the support surface is leveled, so as to improve the installation quality of the photovoltaic module.

[0070] Optionally, in combination with Figure 7 As shown in the figure, the photovoltaic module 100 further comprises a mounting plate 4, and the photovoltaic cell 3 is arranged between the carrier 2 and the mounting plate 4; the mounting plate 4 is provided with a third mounting hole 41 corresponding to the position of the first mounting hole 21, and the air cooling device 12 is embedded in the first mounting hole 21, the second mounting hole 111 and the third mounting hole 41.

[0071] Specifically, the photovoltaic module 100 further comprises a mounting plate 4;

[0072] In combination with Figure 7As shown, if the support member 2 is located above the photovoltaic cell 3, the support member 2 is made of a transparent material that allows sunlight to pass through. The mounting plate 4 can be located at the bottom of the photovoltaic cell 3 so that the support member 2 can protect the photovoltaic cell 3 from above, while the mounting plate 4 can provide support and fixation for the photovoltaic cell 3 from below.

[0073] Combination Figure 8 As shown, if the support member 2 is located below the photovoltaic cell 3, the mounting plate 4 can be located above the photovoltaic cell 3. The mounting plate 4 is made of a transparent material that allows sunlight to pass through, so as to protect the photovoltaic cell 3 from above, while the support member 2 can provide support and fixation for the photovoltaic cell 3 from below.

[0074] Combination Figure 7 and Figure 8 As shown, the first mounting hole 21 of the carrier 2, the second mounting hole 111 of the base 11 and the third mounting hole 41 of the mounting plate 4 are vertically aligned and connected.

[0075] In this optional embodiment, by opening a third mounting hole 41 on the mounting plate 4 corresponding to the position of the first mounting hole 21 of the carrier 2, the two ends of the air-cooling device 12 of the ventilation structure 1 in the vertical direction pass through the first mounting hole 21 of the carrier 2 and the third mounting hole 41 of the mounting plate 4, respectively, and the middle part of the air-cooling device 12 passes through the second mounting hole 111 of the base 11, so that under the rotation of the air-cooling device 12, the air flow between the upper and lower surfaces of the photovoltaic module 100 can be accelerated (see...). Figure 6 As shown, the heat from the bottom of the photovoltaic module 100 is extracted and flows upward through the ventilation structure 1, which in turn causes the cool air below the photovoltaic module 100 to rise naturally, forming a circulation, which can improve the heat dissipation effect of the photovoltaic module.

[0076] Optionally, combined Figure 3 and Figure 7 As shown, the diameters of the second mounting hole 111 at both ends along the thickness direction of the support member 2 are the same.

[0077] Specifically, the thickness direction of the bearing 2 can be parallel to... Figure 3 or Figure 7 The Z-axis direction is parallel.

[0078] The fact that the diameters of the two ends of the second mounting hole 111 along the thickness direction of the support member 2 are the same means that the diameters of the top and bottom ends of the second mounting hole 111 are the same. In other words, the second mounting hole 111 can be a circular hole structure with a first threaded layer 1111 inside.

[0079] In the optional embodiment, the second mounting hole 111 has the same hole diameter at both ends along the thickness direction of the carrier 2, so that the air-cooled device 12 can be mounted into the second mounting hole 111 of the base 11 from above or below the carrier 2, improving the installation flexibility of the air-cooled device 12.

[0080] The photovoltaic system provided by the embodiment of the present disclosure comprises the photovoltaic assembly 100 as described in the above embodiment, and a plurality of photovoltaic assemblies 100 are arranged in an array.

[0081] Specifically, the photovoltaic system can be built in the following manner, for example, the photovoltaic system comprises a plurality of photovoltaic assemblies, each of which can have the ventilation structure 1 described above;

[0082] Alternatively, the photovoltaic system comprises a plurality of photovoltaic assemblies, and a part of the photovoltaic assemblies 100 can have the ventilation structure 1 described above, and another part of the photovoltaic assemblies can not be provided with the ventilation structure 1 described above. The photovoltaic assembly without the ventilation structure 1 can be defined as a conventional assembly 200.

[0083] The photovoltaic system of the embodiment has the same beneficial effects as the photovoltaic assembly 100 described above, which will not be described here again.

[0084] Optionally, in combination with Figure 9 As shown in the figure, the photovoltaic system further comprises a photovoltaic support 300, and the photovoltaic assembly is arranged on the photovoltaic support 300.

[0085] Specifically, in the Figure 9 embodiment, the photovoltaic system comprises a plurality of photovoltaic assemblies 100 and a plurality of conventional assemblies 200, and the plurality of photovoltaic assemblies 100 can be arranged along the Y-axis direction in the coordinate system, and the plurality of conventional assemblies 200 can be arranged along the Y-axis direction in the coordinate system. Figure 9 Figure 9 Specifically, in the

[0086] In the embodiment, the conventional assembly 200 and the photovoltaic assembly 100 can be alternately arranged along the X-axis direction in the coordinate system, in other words, at least one conventional assembly 200 can be arranged between two adjacent photovoltaic assemblies 100, Figure 9 Figure 9 In the embodiment, four conventional assemblies 200 can be arranged between two photovoltaic assemblies 100.

[0087] The photovoltaic support 300 can be used as an intermediate support structure of the photovoltaic assembly 100 and the conventional assembly 200 arranged on the roof of a building, so as to support and fix the photovoltaic assembly 100 and the conventional assembly 200.

[0088] ​​In the related art, in order to realize the ventilation function in a building, for example, a factory building, a plurality of fans are usually arranged on the roof of the building at intervals. Since the photovoltaic assembly is also arranged on the roof of the building, the plurality of fans will affect the laying rate of the photovoltaic assembly in the entire photovoltaic system, thereby affecting the installation capacity of the photovoltaic system.

[0089] In the present disclosure, a ventilation opening can be formed on the roof of a building, for example, the roof of a factory building. When the photovoltaic system is installed on the roof of the building, the ventilation structure 1 of the photovoltaic assembly 100 in the photovoltaic system corresponds to the position of the corresponding ventilation opening of the roof of the building. By the rotating action of the ventilation structure 1 in the photovoltaic assembly 100, the hot air in the building can be extracted. Not only the building can be cooled, but also the air flow around the conventional assembly 200 and the surface of the photovoltaic assembly 100 can be accelerated, so as to quickly cool the conventional assembly 200 and the photovoltaic assembly 100. In short, compared with the plurality of fans arranged on the roof of the building in the related art, which affect the laying rate of the photovoltaic system, the ventilation structure 1 is directly integrated into the photovoltaic assembly in the present disclosure. Not only the cooling operation of the factory building, the conventional assembly 200 and the photovoltaic assembly 100 can be realized, but also the laying rate of the photovoltaic assembly arranged on the factory building can be improved, and the installation capacity and the power generation benefit of the photovoltaic system can be improved.

[0090] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
