[0037] In use, the rear door frame 1 and the closing plate 2 form the rear door assembly. The sound insulation plate 3 divides the space between the rear door frame 1 and the closing plate 2 into two parts and blocks the transmission of noise. Two sets of heat dissipation threaded frames 4 are fixed on both sides of the sound insulation plate 3, while also increasing the fixation between the rear door frame 1 and the closing plate 2. The two sets of heat dissipation threaded frames 4 allow the airflow in the space on both sides of the sound insulation plate 3 to flow towards the middle and into the fixed frame 5. The fixed frame 5 can be used to install and fix the fan motor 6. When the fan motor 6 is powered on, the output end drives the blades to rotate, thereby causing the airflow... The main protective net 7 can prevent foreign objects from entering the fixed frame 5. The four ventilation frames 8 can allow air to enter between the rear door frame 1 and the closing plate 2. The vent holes of the four ventilation frames 8 can allow air from one side of the closing plate 2 to enter both sides of the sound insulation plate 3.
