Abstract

This utility model discloses a high-efficiency heat dissipation set-top box, relating to the field of set-top box technology. The utility model includes a box body serving as a carrier for electronic components, and a heat dissipation mechanism disposed inside the box body. The heat dissipation mechanism achieves efficient heat dissipation from the inside of the box body through airflow, heat conduction, and dust prevention. The heat dissipation mechanism includes a heat-conducting component, which includes a heat dissipation fin assembly. Specifically, this utility model uses a heat-conducting component where a rotating impeller generates a strong airflow. During operation, the heat from the electronic components inside the box is transferred to the heat dissipation fin assembly via heat-conducting pads. An air guide shroud directs the airflow through the assembly, and the heat is discharged through heat dissipation holes, achieving efficient heat exchange and heat dissipation. Compared to traditional perforated heat dissipation, this design significantly improves heat dissipation efficiency, extends component lifespan, and enhances equipment stability. The dustproof mesh on the top cover reduces dust clogging of the heat dissipation fin assembly, lowering the cleaning frequency.
