[0086] When the PCB board 5 is in use, firstly, the two protective shells 6 are fixedly installed on the upper and lower sides of the PCB board 5 with fixing bolts. Then, the two negative pressure fans 9 are turned on. The two negative pressure fans 9 can discharge the hot air generated by the PCB board 5 and the moisture inside the PCB board 5 to the outside through the two activated carbon filters 8 at the top. At the same time, the outside air will also enter the PCB board 5 through the two activated carbon filters 8 at the bottom.
