Problems solved by technology

[0014] Therefore, among the components of the optical disc drive, the parts that dissipate more heat often have component damage due to heat dissipation.
Especially, above-mentioned optical pick-up part 9 dissipates heat a lot during operation, because do not arrange heat dissipation device, so will cause the damage of above-mentioned optical pick-up part 9
[0015] In addition, if the above-mentioned optical pickup part 9 dissipates heat, the light output will decrease, so in order to increase the light output again, it is necessary to increase the current of the ALPC IC.
However, if the current of the above-mentioned ALPC IC increases, there will be damage and wear of components such as LDs constituting the optical pickup unit 9.

Abstract

A cooling device of light picking up component on light driver consists of rotation shaft motor set light picker base plate for providing drive force to drive disc for rotating, light picking up component set on light picker base plate for being able to carry out reciprocal movement along radius direction as using said motor as centre and to record or fetch signal from optical disc, wind blade rotated in one body with said motor for sending partial air stream onto light picking up component.

Description

(1) Technical field [0001] The present invention relates to an optical pickup unit cooling device for an optical disc drive, and more particularly to an optical pickup unit cooling device for an optical disc drive that dissipates heat generated by the optical pickup unit of the optical disc drive. (2) Background technology [0002] figure 1 It is a structural plan view of an optical disc drive in the prior art. As shown in the figure, the main substrate 1 constitutes the skeleton structure of the optical disk drive. A substantially quadrangular through-hole is provided in the center of the main substrate 1, and an optical pickup substrate 3 is provided in the through-hole. [0003] The rear end portion of the above-mentioned optical pickup substrate 3 is connected to the above-mentioned main substrate 1 through a shock-proof component 5. Noise transmission. [0004] The optical pickup substrate 3 is provided with a shaft motor 7 for rotating the optical disc. A turntabl...
