Fan Plug-in Box
ZXR10 GER heat dissipation mode is left dissipation mode. Two
parallel fans from the left side of the chassis (view from the front)
are there to blow air into the chassis. These fans make an air
exhaust vent, at the right side to form a left-to-right air duct.
Cool air-flow generated by the fan exchanges with the hot air-
flow, generated by the board assembly and power supply board.
Main chips generated heat are cooled by means of an aluminum
radiator. Both the air filter of the fan and that of the air intake
vent are installed in the fan plug-in box. Fan plug-in box is
designed with the modular structure, which facilitates
disassembling for maintenance and cleaning. Panel of the fan
plug-in box of ZXR10 GER is shown in
Figure 34.
