Patent ID: 10837632

Abstract:
A helical airflow guide device and a stage light heat dissipation system provided with the helical airflow guide device are provided. The helical airflow guide device comprises an airflow guide main body. The airflow guide main body is provided with multiple protruding portions. The multiple protruding portions are helically arranged, and gaps between adjacent protruding portions form multiple funnel-shaped airflow intake passages. Sizes of openings of the multiple airflow intake passages are different and change gradually. The multiple protruding portions are helically arranged, and the gaps between adjacent protruding portions form the multiple funnel-shaped airflow intake passages, such that entering airflows are circumferentially helical. In addition, the sizes of the openings of the multiple airflow intake passages are different and change gradually, such that the sizes of the airflow intake passages change uniformly, and the helical airflow guide device enables the airflow to enter uniformly, thereby achieving uniform heat dissipation.
