Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
A kind of inverter with radiating redundancy feature, including cabinet body frame 5, the lower floor of cabinet body frame 5 are controlled provided with input
Molding block 4 and output control module 9, reactor 10 are arranged on the rear side of output control module 9, middle level provided with power model 3,
Host computer control module 7 and power module 8, complete machine cooling fan 1 and inductance cooling fan 6, complete machine cooling fan 1 are provided with upper strata
Provided with air outlet 2, the heat dissipation channel of inductance cooling fan 6 is connected with air outlet 2, air outlet 2 opposite side lower floor and in
Layer is provided with air inlet 14, and refrigerating plant 13 is provided with the upper strata to side of air outlet 2, and power mould is provided with power model 3
Block heat sink 12, air inlet 14 and the constituting bar heat dissipation wind channel I 11 of air outlet 2；The refrigerating plant 13 is provided with air inlet and air-out
Mouthful, the heat dissipation wind channel II 15 of air inlet and air outlet composition, it passes through power model heat sink 12.
The power model 3, host computer control module 7 and power module 8 are provided with temperature sensor, temperature sensor and master
Machine control module 7 is connected.
It is provided between the heat dissipation wind channel II 15 and heat dissipation wind channel I 11 of refrigerating plant 13 between division board, division board provided with close
Adhesive layer.
Described at least two of power model heat sink 12, one connects with heat dissipation wind channel I 11, one and heat dissipation wind channel II
15 connections.
The bottom of cabinet body frame 5 is provided with screen pack.
Complete machine cooling fan 1 is automatic adjustable speed blower fan.
The present invention is in specific implementation process：
Equipment only starts complete machine cooling fan 1 under normal circumstances, and cold wind enters after inverter from the external world, passes through heat dissipation wind channel
I 11, it can directly pass through from the surface of power model heat sink 12, in the case where generation air quantity is certain, improve in heat dissipation channel
Ventilation, so as to improve radiating efficiency.Complete machine cooling fan 1 can system auto-control rotation speed of fan as needed, meet a variety of
In the case of radiating requirements, moreover it is possible to reduce energy consumption.Inductance cooling fan 6 can also be opened after temperature rise, and similarly complete machine dissipates
Air-heater 1, is radiated.
When ambient temperature is too high, complete machine cooling fan 1 it is air-cooled can not meet demand when, refrigerating plant 13 starts, refrigeration
Heat dissipation channel is that heat dissipation wind channel II 15 enters working condition, and the cold air that refrigerating plant 13 is produced passes through single heat dissipation channel
Cold air is directly sent to the surface of power model heat sink 12, and heat dissipation wind channel I 11 and heat dissipation wind channel II 15 are separately independent
's.The cold wind that refrigerating plant 13 is exported is less than 15-20 degrees Celsius of ambient temperature, and the cold wind of heat dissipation wind channel II 15 takes away power
The surface more heat transfer of module heat dissipating plate 12 so that the temperature difference occurs in whole inverter internal temperature；Power model heat sink 12 itself
Transmitted for heat transfer, conduction is very fast, so as to reduce the temperature of whole inverter quickly, reaches refrigeration, the fortune of extension device
The row time；Because the wind speed of refrigerating plant 13 is very fast, after the cold wind that refrigerating plant 13 is sent out is by power model heat sink 12, go out
The temperature in air port is still less than ambient temperature, so this partial air directly is transmitted back into refrigeration dress by heat dissipation wind channel II 15
Put 13 air inlet, realize refrigerating plant pass in and out air sealing and circulating, refrigeration wind recycle, increase refrigeration.
