        For any electrical device, heat dissipation must be considered to ensure the good work of the equipment, and the TV box is no exception. As the weather gets hotter, the overheating problem of TV boxes will become more and more serious, and the heat source of the TV box mainly comes from the main board, and the CPU and WiFi module have the highest heat energy.

TV box cooling

     On the one hand, because the TV box generally adopts the chip scheme of the combination of CPU and GPU, the box will generate a lot of heat when working, especially when 4K decoding and games are carried out, the TV box will rise sharply, which we can feel by touching with our hands. On the other hand, the WiFi module needs to maintain signal coverage and data transmission at all times, which will also generate a lot of heat; However, compared with the CPU module, its temperature rise curve is much smoother, and some well optimized high-end TV box WiFi modules will not even rise significantly.

     As the chip module is the main heating component of the TV box, once overheating occurs, the chip and system bear the brunt. Users will obviously feel that the system is slow, stuck, blue screen and flash back; The overheating of WiFi module is reflected in the decline of network transmission speed and obvious network delay. In addition, the aging speed of the motherboard will be faster for TV boxes that have been overheated for a long time.

Pendinginan Pasif:

1.  Nowadays, the shape of TV box is generally miniaturized, and both chips and circuits in the limited body are highly integrated, and its heat dissipation performance is compressed to the extreme; In this case, the heat dissipation methods that can be adopted are very limited. Usually, a heat dissipation iron sheet is installed on the back of the motherboard to reduce the heat of the CPU by using the principle of metal heat conduction.

2. Due to the small body of the box, the heat after the heat dissipation of the iron sheet is still accumulated in the box. On this basis, some manufacturers began to reserve heat dissipation holes on the box shell, or use the metal body to speed up the heat dissipation speed.

 Active Cooling:

      An active heat dissipation module - axial flow exhaust fan (heat dissipation fan) is designed in the box. The heat dissipation performance of the TV box with this design is significantly higher than that of the TV box with passive heat dissipation, but the volume will be larger than that of the general box.
