[0002] A set-top box, also known as a digital video converter box, is a conversion device that converts digital television signals into analog signals. It is widely used in home and commercial environments to receive digital television signals and convert them into analog television signals for playback. When the set-top box is working, it usually requires a corresponding heat dissipation structure to dissipate heat.

This heat dissipation structure cannot effectively conduct and dissipate heat from the inside of the set-top box, resulting in excessively high temperature of the set-top box, affecting its performance and stability.
