In above-mentioned auxiliary power box, unsteady flow device assembly and charging thermomechanical components are fixed on the skeleton within casing 1
On 2, thus having saved installing space and the machine volume of auxiliary power box, also convenient development is installed simultaneously
And maintenance work.This auxiliary power box in radiation processes, electric operation ordering about outside casing 1 on blower fan 29
The air in portion sucks within casing 1 from air inlet 15, and moving air flows through dissipating of charger power cell 20
The radiator of hot device and converter module 25 simultaneously takes away heat produced by the two, in the effect of blower fan 29
Under, moving air passes sequentially through two fans entrances 292, blower fan 29 and air channel 19 and blows to direct current reactor
31 and isolating transformer 30, and by transformator 30 lower section and the air outlet blowout that is located on base plate 14,
Wherein, the caloric value of charger power cell 20 and converter module 25 is higher, direct current reactor 31
Take second place with the caloric value of isolating transformer 30, therefore by charger power cell 20 and converter module 25
The updrift side being arranged on moving air to make the two preferentially be radiated, because the radiator of the two is right respectively
Accurate two fans entrances 292, so charger power cell 20 and converter module 25 can obtain simultaneously
To radiating, finally by the two, the moving air after radiating blows to direct current reactor 31 and isolating transformer 30.
In said process, in conjunction with the heat grade of each building block in casing 1, and by the conjunction to each building block
Removing the work office is so that this auxiliary power box, on the basis improving whole machine integrated level, achieves more excellent radiating
Effect.Further, since only a blower fan 29 need to be arranged, so the present invention compares existing adopting within casing 1
For auxiliary power box with multiple heat abstractors, further reduce small product size, save product cost,
And control circuit is simpler.
