[0028] Embodiment 1: This embodiment is a photovoltaic module cooling device, including a water tank and a water diversion cotton core, wherein the water tank is used to store water, the water diversion cotton core adopts a cotton core with a thickness of 10 mm, and the water diversion cotton core is divided into a water absorption section, a water delivery section and a cooling section from one end to the other end, wherein the water absorption section of the water diversion cotton core is immersed in the water tank, and the cooling section of the water diversion cotton core is glued to the back of the photovoltaic module, and the cooling section is spirally attached to the back of the photovoltaic module.

[0029] In this example, the water absorption section immersed in the water tank will drive the water in the water tank to flow to the cooling section on the back of the photovoltaic module through the water delivery section due to the capillary action of the cotton core. The water absorbs heat in the cooling section to reduce the photovoltaic temperature.

[0030] Example 2: This example is basically the same in structure as Example 1, the only difference being that in this example the water sink is equipped with a water replenishing mechanism, which can obtain the water level information in the water sink through a water level sensor, and when the water level information shows that it is lower than a preset low water level, the water replenishing mechanism automatically fills water into the water sink through a water pump until the water level information shows that it reaches a preset high water level.

[0031] Embodiment 3: This embodiment is a support system, including: a bracket body, a water tank and a water diversion cotton core, etc., wherein the top of the bracket body is used to install photovoltaic components, and the bracket body has four columns located at four corners, including two front columns and two rear columns.

[0032] In this example, the water tank is installed on the bracket body below the photovoltaic module via a vertical support assembly and a horizontal support assembly. The vertical support assembly is used to limit the vertical displacement of the water tank, and the horizontal support assembly is used to limit the horizontal displacement of the water tank.

[0033] In this embodiment, the vertical support assembly has a tray arranged at the bottom of the water tank, the tray is connected to the front column of the bracket body via a horizontal support rod, one end of the horizontal support rod is connected to the front column via a clamp, and the other end of the horizontal support rod is connected to the tray by a bolt. An oblique support rod is arranged between the horizontal support rod and the front column, one end of the oblique support rod is connected to the front column via a clamp, and the other end is connected to the middle of the horizontal support rod via a bolt.

[0034] In this example, the horizontal support assembly has a clamp fixed to the upper part of the water tank, and the clamp is connected to the front column and the rear column of the bracket body through two horizontal support rods. One end of the horizontal support rod is connected to the corresponding front and rear columns through the clamp, and the other end of the horizontal support rod is connected to the clamp on the water tank. An oblique support rod is provided between the horizontal support rod and the column, and one end of the oblique support rod is connected to the column through the clamp, and the other end is connected to the middle of the horizontal support rod through a bolt.

[0035] In this embodiment, the water diversion cotton core adopts a cotton core with a thickness of 10 mm.

The water absorption section of the water diversion cotton core is immersed in the water tank, and the cooling section of the water diversion cotton core is glued to the back of the photovoltaic module. The cooling section is spirally attached to the back of the photovoltaic module.

[0036] In this example, the water absorption section immersed in the water tank has capillary action on the cotton core, which drives the water in the water tank to flow through the water delivery section to the cooling section on the back of the photovoltaic module. The water absorbs heat in the cooling section to reduce the photovoltaic temperature.
