Further, the fan assembly includes two groups of blower fans of A and B, and two groups of blower fans have its independent ventiduct；
A groups blower fan sets right side heel row, the radiating for reactor；
B group blower fans are arranged on right side front row, the radiating for the IGBT and filtering unit of power unit assembly.
Further, described device also includes radiator, and the radiator is arranged among stratum, nearest from A group blower fans
Position, to meet the radiating of heat generating component.
Further, the housing unit includes air-out cover plate, and the air-out cover plate is arranged on the left side of device.
Further, the class of insulation of the reactor assemblies is F levels.
Further, the air channel of described device is divided into upper, middle and lower-ranking；
Upper strata is Natural Heat Convection layer, in, be air blast cooling layer lower two layers, each layer is independent ventiduct design.
Further, air-out on the left of air intake on the right side of described device, waterproof air channel and the device air channel of left and right are directly connected to shape
Integral air channel.
The beneficial effects of the utility model are：
The utility model is compact-sized, good heat dissipation, air inlet/outlet are novel, easy to maintenance, specific as follows：
1st, the utility model air channel is divided into upper, middle and lower-ranking.Upper strata is Natural Heat Convection layer, this layer assembly, caloric value
Small, free convection can meet its radiating requirements.In, be air blast cooling layer lower two layers, be independent ventiduct design.
2nd, the utility model wind direction is air-out on the left of air intake on the right side of device, is positioned over outdoor JP cabinets, only needs above smaller
Installing space, the waterproof air channel of left and right is directly connected to form overall air channel with device air channel.
3rd, panel of the present utility model is separated with switch, indicator lamp, and device indicator lamp and switch need not be removed by removing panel
Line.
4th, the utility model program of device upgrading need not remove panel, as long as backing out the bolt of wicket on panel and exempting to use
