Problems solved by technology

Existing power communication management machines generally adopt a passive heat dissipation method, that is, heat dissipation holes are provided on the casing, and heat dissipation is realized through natural convection of the air. This heat dissipation method has low heat dissipation efficiency. When the temperature inside the casing is high, the To ensure rapid heat dissipation, it is necessary to open a large area of ​​heat dissipation holes on the shell. Although the heat dissipation performance is ensured, the probability of dust entering the shell is increased. The accumulation of dust inside the management machine will adversely affect its normal operation. Moreover, after the dust covers the motherboard, the heat dissipation performance of the management machine will be gradually lost.
