As improvement, arranging of fin is herringbone, and the fin that herringbone is arranged comprises upper end, left extension and right extension; The fin of upper end is provided with described groove, and the groove that is positioned on the fin of upper end is interconnected; The fin of left side extension is provided with described groove, and the groove that is positioned on the left extension is interconnected; The fin of right extension is provided with described groove, and the groove that is positioned on the right extension is interconnected.The fin that herringbone is arranged is set, is convenient to the moulding fin on the one hand, be convenient to the wind groove of wind Slot shaping for connecting, the appearance looks elegant of whole on the other hand lamp pearl radiating seat.Because the wind groove is longer, on fin on upper end fin, the left extension and the fin on the right extension, groove is set all, is convenient to reduce windage, to improve radiating effect.
As improvement, a side that is positioned at fin on the lamp pearl installing plate is provided with jut, is formed with containing cavity in the jut, and lamp pearl installing plate is provided with through wires hole that is connected with containing cavity and the through hole that supplies motor output shaft to pass.Described containing cavity is convenient to ccontaining CD-ROM drive motor, to save the installing space of CD-ROM drive motor.
As improvement, the outer wall of jut is provided with radiating ribs.Radiating ribs is set, improves the radiating rate of lamp pearl installing plate on the one hand, improve the radiating rate of jut itself on the other hand, thus the service life of improving CD-ROM drive motor.
As improvement, lamp pearl installing plate is provided with upwardly extending flange with the relative side of fin is installed, and is formed with spatial accommodation in the flange.Described spatial accommodation is used for installation base plate and led chip, flange is set helps water proof and dust proof.
As improvement, described flange outer sides is provided with the muscle sheet, is provided with reinforcement between flange outer sides and the lamp pearl installing plate.The bonding strength that reinforcement can improve flange and lamp pearl installing plate is set, and the muscle sheet can improve radiating effect.
As improvement, lamp pearl installing plate is provided with the installation position, and the installation position is provided with installing hole.Installation position and installing hole are set to be convenient to lamp pearl plate radiating seat is installed on the support.
