Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Embodiment one: as shown in Figs. 1-2, a kind of moisture-proof three-phase imbalance regulating device, including IGBT substrate 5, cabinet 1,
The upper end of the cabinet 1 is equipped with upper fan group 2, and lower end is equipped with lower fan group 3, and upper fan group 2 includes two upper 21 Hes of extraction fan
Two up-draught fans 22, lower fan group 3 include two lower extraction fans 32 and two lower blower fans 31, the extraction fan and blowing
Fan is spaced apart；The inside of cabinet is equipped with the master controller (not shown) being made of one chip microcomputer, the lower fan
Drier 4 is equipped between group 3 and IGBT substrate 5；Electric thermo-couple temperature inductor is provided with (in figure not in the IGBT substrate 5
Display)；Temperature inductor, upper fan group 2 and the lower fan group 3 is connected with master controller.The cabinet 1 it is left and right
Narrow bar is equipped on side wall, and upper end has the heat release hole of the dust-proof the brim of a hat, further includes a V-arrangement water fender (not shown),
The V-arrangement water fender is connected by several columns with the upper surface of cabinet 1, the air inlet/outlet of the extraction fan and blower fan
Filter screen (not shown) is equipped at mouthful.
Working condition:
When the temperature of temperature sensor senses to each IGBT substrate 5 is lower, the moisture contained in humid air at this time holds
Easily liquefy on IGBT substrate surface, so main controller issues signal at this time, the work of upper extraction fan 21 in upper fan group 2, on blow
Fan 22 stops, and the lower blower fan 31 in lower fan group 3 works, and lower extraction fan 32 stops, i.e., humid air first passes around drying
The moisture carried in air is transferred to the active carbon in drier 4 to fully absorb by the drying process of device 4, then will be dry empty
Gas flows into inside cabinet 1, and radiates to IGBT substrate 5.The flow direction of air is as indicated by the arrows in fig. 3 at this time.
And when the temperature of temperature sensor senses to each IGBT substrate 5 is higher, temperature sensor transmits signal at this time
To master controller, the upper extraction fan 21 in main controller controls in fan group 2 stops, up-draught fan 22 works, in lower fan group 3
Lower blower fan 31 stop, lower extraction fan 32 works, i.e., outside air contacts each IGBT substrate first, and absorbs its surface heat
Amount, is converted to hot-air, drying device 4, and be finally expelled to outside cabinet 1 by fan 3.Hot-air can take away drying at this time
In device 4 active carbon last stage in the portion of water that absorbs, and convenient for the absorption of next time.The flow direction of air is such as at this time
Shown in arrow in Fig. 4.
Wherein, working condition shown in Fig. 4 is main operating mode, reason are as follows: on the one hand meet activated carbon adsorption it is fast,
Slow feature is desorbed, the air-cooled radiating mode of another aspect mainstream is also based on being vented to cabinet lower end, because arranging to lower end
The radiating mode of gas can take away more heats.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
