[0025] Furthermore, the heat dissipation assembly includes a fixed plate 13 and a ventilation fan 14. The fixed plate 13 is fixedly connected in the movable groove 3. The bottom of the fixed plate 13 is fixedly connected to the support frame 1. Five groups of ventilation fans 14 are equidistantly arranged on the right side of the fixed plate 13. The diameters of the five groups of ventilation fans 14 are consistent with the heat dissipation groove 8.
