Description

Technical Field

[0001] The present invention relates to the technical field of projector heat dissipation, and more particularly to a heat dissipation device for a laser projector. Background Art

[0002] A laser projector heat sink is designed to address the heat generated during operation, improve power generation efficiency, and extend the life of the device. Laser projectors generate a significant amount of heat during extended operation. If this heat is not dissipated promptly, it can affect the projector's performance and stability.

[0003] In existing technologies, firstly, some devices cannot effectively direct heat in a specific direction, which may cause heat to accumulate inside the laser projector, affecting the working efficiency and lifespan of the laser projector. The heat cannot be discharged through accelerated rotational motion, resulting in reduced heat dissipation efficiency, especially under high temperature or high load conditions. Secondly, some devices cannot adjust the rotation speed of the heat diversion mechanism as needed, which may lead to poor heat dissipation or excessive heat dissipation. The rotation of the heat diversion function may not be stable and is greatly affected by external conditions. Finally, some devices will become more difficult to operate, increasing the complexity and time cost of maintenance. The lack of precise adjustment may make it impossible to achieve precise control of the heat diversion function, reducing the adaptability and flexibility of the device. Summary of the Invention
