When the solar photovoltaic panel is working, the output power of the photovoltaic panel will decrease with the increase of temperature, and usually the efficiency will decrease by about 0.5% per 1℃ increase. In addition, high temperature will also accelerate the aging of materials and shorten the service life of the photovoltaic panel. Therefore, it is necessary to carry out thermal management on the photovoltaic panel to ensure the high performance output of the photovoltaic panel.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] The present invention provides a solar photovoltaic thermal management system with organic wastewater degradation function, which is implemented as follows: Figure 1 As shown, it includes a water storage unit 10 , a sewage degradation unit 20 and a clean water storage unit 30 .

[0029] Regarding the water storage unit 10, Figure 1 As shown, the water storage unit 10 is used to input the stored sewage into the sewage degradation unit 20 for degradation treatment, that is, the main function of the water storage unit 10 is to store and transport sewage. Therefore, in order to achieve this purpose, this embodiment first uses aluminum alloy to make a water storage unit 10 with a sewage storage cavity, which is not only low in cost but also has high corrosion resistance, thereby being able to meet the storage function of various sewage. Secondly, when transporting sewage, this embodiment uses a water pump to pump the sewage from the inside of the water storage unit 10 to the sewage degradation unit 20, thereby realizing the transportation of sewage.

[0030] Regarding the sewage degradation unit 20, Figures 1 to 5 As shown, the sewage degradation unit 20 includes a heat dissipation frame 21 , a solar photovoltaic panel 22 , a glass plate 23 and photothermal microcapsules 24 .

[0031] The heat dissipation frame 21 has a rectangular shape, and a degradation chamber 211 is provided inside the heat dissipation frame 21. In the direction shown in the figure, the degradation chamber 211 penetrates the left and right sides of the heat dissipation frame 21, so that the degradation chamber 211 can be connected and communicated with the water storage unit 10 and the purified water storage unit 30 respectively; and because the heat dissipation frame 21 is arranged tilted with the left lower and the right higher in the direction shown in the figure, the degradation chamber 211 is also arranged tilted. At this time, the upper part of the degradation chamber 211 will be connected and communicated with the water storage unit 10, and the lower part of the degradation chamber 211 will be connected and communicated with the purified water storage unit 30.

[0032] In addition, the heat dissipation frame 21 is provided with a photolysis groove 212 and a plurality of mounting cavities 213 above the degradation cavity 211; the photolysis groove 212 penetrates from the top surface of the heat dissipation frame 21 to the inside of the degradation cavity 211, so that the photolysis groove 212 is in communication with the degradation cavity 211; and the mounting cavity 213 is a cavity structure formed by recessing inward from the top surface of the heat dissipation frame 21, and the plurality of mounting cavities 213 are arranged separately from each other, so that the area where the plurality of mounting cavities 213 are separated from each other can be provided with the photolysis groove 212; for example, the total number of mounting cavities 213 in this embodiment is four, and after arranging the four mounting cavities 213 in a matrix form, the photolysis groove 212 can be arranged in a cross shape, so that the photolysis groove 212 can realize the separation of the four mounting cavities 213.

[0033] Further, since the heat dissipation frame 21 needs to be used for mounting the solar photovoltaic panel 22 and the photo-thermal microcapsule 24, in order to facilitate efficient heat transfer of the solar photovoltaic panel 22 and prevent the photo-thermal microcapsule 24 from corroding the heat dissipation frame 21, this embodiment sets the heat dissipation frame 21 as an aluminum alloy frame, so as to utilize the excellent heat conduction performance of aluminum alloy to improve the heat transfer efficiency of the solar photovoltaic panel 22, and utilize the stable chemical properties of aluminum alloy to improve the corrosion resistance of the heat dissipation frame 21.

[0034] Obviously, after the heat dissipation frame 21 is arranged in the above manner, a plurality of solar photovoltaic panels 22 can be arranged in the plurality of mounting cavities 213 respectively, so as to realize the separate mounting and fixing of the plurality of solar photovoltaic panels 22; wherein the solar photovoltaic panel 22 in this embodiment is a photovoltaic panel made of silicon.

[0035] In order to avoid the photo-thermal microcapsule 24 in the photolysis groove 212 from corroding the solar photovoltaic panel 22, this embodiment uses the glass plate 23 to cover and seal the photolysis groove 212 and the plurality of mounting cavities 213, so that the photolysis groove 212 and the plurality of mounting cavities 213 form independent sealed spaces, thereby providing good mounting protection for the solar photovoltaic panel 22.

[0036] Finally, in order to realize the degradation effect on sewage, this embodiment fills the photo-thermal microcapsule 24 in the degradation cavity 211 and the photolysis groove 212.

[0037] Specifically, the photo-thermal microcapsule 24 in this embodiment includes a core layer material and a shell layer material, and the shell layer material is wrapped outside the core layer material; the core layer material is one or more of C14-C22 alkane or C14-C22 fatty alcohol; the shell layer material is silicon dioxide; and the plasmonic material ion compound is chloroauric acid, copper nitrate or silver nitrate.

[0038] The preparation method of the photo-thermal microcapsule 24 is as follows:

[0039] S1. Ultrasonic stirring of core-shell phase change microcapsules in an n-type semiconductor precursor is performed to obtain semiconductor-encapsulated double-shell phase change energy storage microcapsules by a hydrothermal method;

[0040] S2. Dispersing the double-shell structure phase change energy storage microcapsules into an aqueous solution containing a plasmon material ionic compound, and stirring under light conditions to obtain the photothermal microcapsules 24.

[0041] The photothermal microcapsules 24 of this embodiment include exposed microcapsules 241 and internal microcapsules 242 . The exposed microcapsules 241 are disposed in the photolysis tank 212 , and the internal microcapsules 242 are disposed in the degradation chamber 211 , and the exposed microcapsules 241 and the internal microcapsules 242 are in contact with each other.

[0042] The exposed microcapsules 241 can be more fully exposed to sunlight, so that after absorbing solar energy, the catalytic properties of themselves and the internal microcapsules 242 can be stimulated. During this process, the shell material of the photothermal microcapsules 24 will absorb and store the excess heat energy after the catalysis and part of the heat of the solar photovoltaic panel 22. The photothermal microcapsules 24 with stimulated catalytic ability will react with the organic matter in the sewage to achieve the degradation of the sewage. During this process, the flow of sewage under the solar photovoltaic panel 22 further reduces the temperature of the solar photovoltaic panel 22. After two heat absorptions, the temperature of the solar photovoltaic panel 22 can be maintained in a suitable range, so that it can maintain high performance output; the treated water finally flows into the clean water storage unit 30 for storage.

[0043] In addition, in order to increase the contact area between the photothermal microcapsules 24 and the sewage, this embodiment also compresses the internal microcapsules 242 into a tube shape, so that the internal microcapsules 242 can undergo a more complete degradation reaction with the sewage, greatly improving the degradation treatment efficiency of the sewage.

[0044] Regarding the clean water storage unit 30, Figure 1 As shown, the clean water storage unit 30 is used to store the clean water treated by the sewage degradation unit 20. Therefore, in order to achieve this purpose, this embodiment uses aluminum alloy material to make the corresponding liquid storage tank, which can complete the storage and collection of clean water.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
