Digital TV has entered thousands of households, and the demand for wireless digital TV receiving devices as a necessary accessory is also increasing.

[0003] The main circuit board of a wireless mobile digital TV receiver will generate a lot of heat when working at a high load for a long time. In addition, the internal space of the wireless mobile digital TV receiver is small. In order to dissipate the heat of the main circuit board of the receiver, usually only heat dissipation holes are opened on the side of the shell. The heat dissipation effect of this design is poor. When the main circuit board of the TV receiver fails, the circuit main board needs to be disassembled and assembled. The disassembly and assembly steps of the circuit main board are cumbersome, which makes the maintenance efficiency low. Therefore, we propose a wireless mobile digital TV receiver.
