Specifically, the roller 2 is used for conveying solar cells, and the fan main body 6 located below the roller 2 can perform air cooling and heat dissipation on the solar cells on the roller 2. The wind blown out from the fan main body 6 enters the flow dividing box 7 through the fan housing 702 and the first through hole 701, the fan port 601 is located in the fan housing 702, and the fan housing 702 can allow all the wind generated from the fan main body 6 to enter the flow dividing box 7. Then, the air is split through the second splitter plate 704, flows out through the first ventilation holes 705, flows out through the second ventilation holes 706, and then the air generated by the fan main body 6 is uniformly blown to the solar cell, so that the heat dissipation effect is improved.

The support frame 1, the support legs 3, the first fixing frame 4 and the second fixing frame 5 mainly play a role in supporting and fixing, and the shunt box 7 is fixed on the support legs 3.

Further, a first splitter plate 703 matched with the second splitter plate 704 is further disposed in the splitter box 7, and a third ventilation hole 707 intersecting with the first ventilation hole 705 is formed in the first splitter plate 703.

Specifically, when the wind generated by the fan main body 6 enters the lower portion of the first flow dividing plate 703 through the first ventilation hole 705, the third ventilation holes 707 intersecting with the first ventilation holes 705 are formed in the first flow dividing plate 703. That is, when the wind generated from the fan main body 6 flows out through the first ventilation hole 705, it is blocked by the upper first flow dividing plate 703, and then flows out through the third ventilation hole 707. That is, the wind generated by the fan main body 6 is further split, so that the wind is uniformly blown out through the second ventilation holes 706, and a better heat dissipation effect is achieved.

Further, the second ventilation hole 706 is an inclined hole, the inclination angle is 20 degrees to 30 degrees, and the inclination direction of the second ventilation hole 706 is opposite to the rotation direction of the roller 2.
