[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the present application provides an air flow channel photovoltaic thermal device based on a vortex generator, comprising: at least one photovoltaic thermal component 1; wherein each photovoltaic thermal component 1 comprises: a solar panel 11, at least one first fixing component 12, at least one second fixing component 13 and at least one vortex generator 14. One end of the solar panel 11 is connected to the installation position 15 through the first fixing component 12, and the other end of the solar panel 11 is connected to the installation position 15 through the second fixing component 13. After the connection, a ventilation area is formed between the solar panel 11 and the installation position 15; the vortex generator 14 is arranged in the ventilation area and connected to the solar panel 11; when the operating temperature of the solar panel 11 exceeds a preset value, the solar panel 11 completes heat exchange through the vortex generator 14, thereby reducing the operating temperature of the solar panel 11.

[0025] Specifically, since the first fixing component 12 and the second fixing component 13 have their own heights, when the solar panel 11 is connected to the installation position 15 through the first fixing component 12 and the second fixing component 13, there is a gap between the solar panel 11 and the installation position 15, and the gap is the ventilation area.

[0026] The installation location 15 is a building roof, but is not limited to a building roof. The present application preferably uses a building roof.

[0027] The specific number of the first fixing components 12 depends on the actual situation, and one is preferred in the present application.

[0028] The specific number of the second fixing components 13 depends on the actual situation, and one is preferred in the present application.

[0029] The vortex generator 14 is located between the first fixing assembly 12 and the second fixing assembly 13. The specific number of the vortex generator 14 is determined according to the actual situation, and one is preferred in this application. The specific value of the preset value is set according to the actual situation.

[0030] Further, such as Figure 2 As shown, the structure of the first fixing component 12 is the same as that of the second fixing component 13, and both include at least: a fixing rod 121; wherein, at least one fixing piece 122 is provided at the bottom of the fixing rod 121, and is detachably connected to the installation position 15 through the fixing piece 122; and at least one buckle 123 is provided at the top of the fixing rod 121, and is buckled with the solar panel 11 through the buckle 123.

[0031] Specifically, the fixing member 122 is detachably connected to the installation position 15, but is not limited to detachable connection. The present application preferably uses detachable connection for easy installation and removal. The solar panel 11 is detachably connected to the installation position 15 through the first fixing component 12 and the second fixing component 13.

[0032] Further, as an embodiment, there are multiple fixing members 122 , and the multiple fixing members 122 are arranged at intervals at the bottom of the fixing rod 121 .

[0033] Specifically, a plurality of fixing members 122 are arranged at intervals at the bottom of the fixing rod 121. The specific number of the fixing members 122 is determined according to actual conditions, and two are preferred in this application.

[0034] Further, as another embodiment, a plurality of fixing members 122 are evenly spaced and arranged at the bottom of the fixing rod 121 .

[0035] Further, as an embodiment, there are multiple buckles 123 , and the multiple buckles 123 are arranged at intervals on the top of the fixing rod 121 .

[0036] Specifically, a plurality of buckles 123 are arranged at intervals on the top of the fixing rod 121. The specific number of the buckles 123 depends on the actual situation, and two buckles are preferred in this application.

[0037] Further, as another embodiment, a plurality of buckles 123 are evenly spaced and arranged on the top of the fixing rod 121.

[0038] Furthermore, a slide groove 1211 is provided at the top of the fixing rod 121 , one end of the buckle 123 is provided in the slide groove 1211 , and is slidably connected to the fixing rod 121 through the slide groove 1211 , and the other end of the buckle 123 is engaged with the solar panel 11 .

[0039] Specifically, the buckle 123 is slidably connected to the fixing rod 121 via the sliding groove 1211 , so that the clamping position of the buckle 123 can be adjusted easily.

[0040] Furthermore, the other end of the buckle 123 is snapped into the edge position of the outer side of the solar panel 11 , but is not limited to being snapped into the edge position of the outer side of the solar panel 11 . The present application preferably snaps into the edge position of the outer side of the solar panel 11 .

[0041] Further, such as Figure 4 As shown, the vortex generator 14 at least includes: a top plate 141 and a bottom plate 142; wherein, a plurality of blades 143 are spaced apart between the top plate 141 and the bottom plate 142, and an air duct is formed between two adjacent blades 143, and the air duct is connected to the ventilation area; the top of the top plate 141 contacts the bottom of the solar panel 11; and the bottom of the bottom plate 142 contacts the installation position 15.

[0042] Furthermore, a plurality of blades 143 are evenly spaced apart and arranged between the top plate 141 and the bottom plate 142 .

[0043] Specifically, the specific number of blades 143 is determined according to actual conditions. When the operating temperature of the solar panel 11 is too high (i.e., the operating temperature of the solar panel 11 is greater than a preset value), the solar panel 11 transfers its own high temperature to the vortex generator 14 located at the bottom of the solar panel 11, and cold air enters from the ventilation area on one side of the solar panel 11. The cold air passes through the air duct of the vortex generator 14 and simultaneously exchanges heat with the vortex generator 14, thereby reducing the temperature of the vortex generator 14. The vortex generator 14 then exchanges heat with the solar panel 11, thereby reducing the operating temperature of the solar panel 11, thereby preventing the operating efficiency of the solar panel 11 from being reduced due to its own excessively high operating temperature. After heat exchange with the vortex generator 14, the cold air is converted into hot air, and the hot air is discharged through the ventilation area on the other side of the solar panel 11. The discharged hot air can be used for low-temperature waste heat utilization in the later stage.

[0044] Furthermore, each blade 143 is arranged to be inclined, and the sum of the inclination angles between any two adjacent blades 143 is N degrees.

[0045] Specifically, the contact area between the vortex generator 14 and the cold air is increased by the blades 143 , thereby improving the efficiency of heat exchange between the vortex generator 14 and the cold air.

[0046] Furthermore, the specific value of N degrees is set according to actual conditions, and the preferred value in this application is N degrees = 180 degrees.

[0047] Specifically, the sum of the inclination angle a of one blade 143 between two adjacent blades 143 and the inclination angle b of the other blade 143 between the two adjacent blades 143 is equal to 180 degrees.

[0048] Further, such as Figure 3 As shown, each photovoltaic thermal assembly 1 also includes: at least one first partition 16 and at least one second partition; wherein the top of the first partition 16 contacts the bottom of one end of the solar panel 11, the bottom of the first partition 16 contacts the installation position 15, and the first partition 16 is located between the first fixed assembly 12 and one end of the vortex generator 14; the top of the second partition contacts the bottom of the other end of the solar panel 11, the bottom of the second partition contacts the installation position 15, and the second partition is located between the second fixed assembly 13 and the other end of the vortex generator 14.

[0049] Specifically, the specific number of the first partition 16 is determined according to the actual situation, and the preferred number in this application is one. The specific number of the second partition is determined according to the actual situation, and the preferred number in this application is one.

[0050] Furthermore, the ventilation area is located between the first partition 16 and the second partition, and the cold air is restricted to flow through the ventilation area through the first partition 16 and the second partition. The cold air enters the ventilation area on one side of the solar panel 11 and is discharged from the ventilation area on the other side of the solar panel 11, which can prevent the cold air from leaking from both ends of the solar panel 11 and improve the flow efficiency of the cold air in the ventilation area.

[0051] Furthermore, there are multiple photovoltaic thermal components 1, and the multiple photovoltaic thermal components 1 are installed at the installation position 15 in a rectangular matrix arrangement, but are not limited to being installed at the installation position 15 in a rectangular matrix arrangement. The present application preferably installs them at the installation position 15 in a rectangular matrix arrangement.

[0052] Further, such as Figure 1 As shown, a baffle 17 is provided between the solar panels 11 of two adjacent photovoltaic thermal assemblies 1. The baffle 17 seals the gap between the solar panels 11 of the two adjacent photovoltaic thermal assemblies 1 to prevent rainwater from penetrating.

[0053] The air flow channel photovoltaic thermal device based on the vortex generator of the present application can cool the solar panel, thereby preventing the solar panel from operating at too high a temperature and affecting the power generation efficiency.

[0054] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the scope of protection of the present application is intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application. Obviously, those skilled in the art may make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the protection scope of the present application and its equivalent technology, the present application is also intended to include these modifications and variations.
