Second heat dissipation windows 3 are provided in the middle of the other two side walls of the set-top box housing 1. An indicator light 4 is provided on one side of the upper end of the set-top box housing 1. A switch 5 is provided on the side wall of the set-top box housing 1 on one side of the first heat dissipation window 2. A front support plate 6 is provided on one side of the lower end of the set-top box housing 1. A rear support plate 7 is provided on the side of the lower end of the set-top box housing 1 far from the front support plate 6. A heat dissipation plate 8 is provided in the middle of the lower end of the set-top box housing 1 between the front support plate 6 and the rear support plate 7. Heat sinks 9 are provided at the lower end of the heat dissipation plate 8. Heat dissipation arc surfaces 10 are provided on both side walls of the heat sinks 9. A first dust-proof net 11 is provided on the inner wall of the set-top box housing 1 close to the first heat dissipation window 2. A second dust-proof net 12 is provided on the inner wall of the set-top box housing 1 close to the second heat dissipation window 3. A heat dissipation fan 13 is provided in the middle of the inner top end of the set-top box housing 1.
[0023] Among them, both the first heat dissipation window 2 and the second heat dissipation window 3 are formed on the side wall of the set-top box housing 1. The indicator light 4 is embedded in the upper end of the set-top box housing 1. The switch 5 is embedded in the side wall of the set-top box housing 1. The front support plate 6 is formed at the lower end of the set-top box housing 1. The indicator light 4 can display the working state of the set-top box. The first heat dissipation window 2 and the second heat dissipation window 3 contribute to the heat dissipation of the set-top box.
[0024] Among them, the rear support plate 7 is formed at the lower end of the set-top box housing 1. The heat dissipation plate 8 is connected to the lower end of the set-top box housing 1 by screws. The front support plate 6 and the rear support plate 7 can support the set-top box housing 1 at the lower end of the set-top box housing 1. The upper end of the heat sink 9 is welded to the lower end of the heat dissipation plate 8. The heat dissipation arc surface 10 is formed on the side wall of the heat sink 9. The components inside the set-top box can be installed on the heat dissipation plate 8. The heat dissipation plate 8 can conduct the heat of the components inside the set-top box to the heat sink 9 during the operation of the set-top box. The heat dissipation arc surface 10 can greatly increase the contact area between the heat sink 9 and the air, so that the heat sink 9 has better heat dissipation performance.

During operation, it can promote the air circulation inside and outside the set-top box through the first heat dissipation window 2, the second heat dissipation window 3 and the heat dissipation plate 8 to dissipate heat from the inside of the set-top box. The heat dissipation plate 8 is of a mesh structure, having good air permeability and heat dissipation effect.

The heat dissipation plate 8 can conduct the heat of the components inside the set-top box to the heat sink 9 during the operation of the set-top box. The heat dissipation arc surface 10 can greatly increase the contact area between the heat sink 9 and the air, making the heat sink 9 have better heat dissipation performance. Since the lower end of the set-top box is supported by the front support plate 6 and the rear support plate 7, it can make the lower part and the surrounding of the heat sink 9 have good contact with the air, having an excellent heat dissipation effect on the set-top box.
