Description
Technical field
The present invention relates to a kind of power device radiators being mounted in elevator control cabinet.
Background technique
As shown in Figure 1, the elevator control cabinet of existing tool power device radiator, the air inlet 21 of its underpart and top
Air outlet 22 be all provided on the back plate 20a of control cabinet 20；Radiator 24 is vertically-mounted inwardly by fin；Cooling fan 23
In the top of radiator 24；Power device 25 is attached to the back side of radiator 24.
Obviously, which can not form independent air duct in control cabinet 20, and the stroke in entire air duct is longer；Again
In addition the wind speed of the air intake surface side of cooling fan 23 is lower, keep the heat dissipation effect of package unit very poor.To ensure elevator controlling
Temperature in cabinet is unlikely to just use larger sized radiator 24 and greater number of cooling fan beyond safety value
23, this not only adds costs, also make the volume of entire control cabinet 20 bigger than normal.In addition, the mode of air inlet/outlet limits control after cabinet
The installation site of cabinet 20 processed installs it from being close to computer room or well enclosure, brings inconvenience to the civil engineering arrangement of elevator.
As shown in Fig. 2, the existing air blast type of cooling, cooling fan 31 is located at the radiator 32 equipped with power device 33
Lower section, and close to the end face of radiator 32.This type of cooling, cold air are blown into the fin of radiator 32 via cooling fan 31
Between, although making which give higher speed, because the air-flow of outflow cooling fan 31 causes entry into heat dissipation in vortex shape
Air-flow uneven distribution between 32 fin of device, it is suppressed that radiator 32 plays optimal cooling effect.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of power device radiators, it may be implemented to radiate excellent
Good, low-cost goal of the invention, and make to realize thin design using the elevator control cabinet of this device, it is arranged convenient for civil engineering.
In order to solve the above technical problems, the technical solution of power device radiator of the present invention are as follows:
Including air inlet duct 11, exhaust passage 12, exhaust passage 12 is located at the top of air inlet duct 11, exhaust passage 12 and air inlet duct 11 it
Between be provided with radiator 14；The air inlet 11a of the air inlet duct 11 and air outlet 12a of exhaust passage 12 is opened in the front cover of control cabinet 10
On plate 10a, air outlet 12a is located at the top of air inlet 11a；The outlet end of air inlet duct 11 is provided with cooling fan 13, cooling wind
Fan 13 connects the radiator 14 by deflector 15；The mounting means of cooling fan 13 makes that its outlet air is face-up and outlet air surface hangs down
Directly in control cabinet rear plate 10b；The fin 14a of radiator 14 is vertically-mounted towards the control direction cabinet rear plate 10b；If deflector 15 by
Dry rectangular plate-like flow deflector is arranged by certain interval；Power device 16 is directly attached to the radiator base plate of radiator 14
14b without fin side.
On the length direction of control cabinet 10, the spacing between the air outlet 12a and air inlet 11a is no more than radiator
14 with the total length of deflector 15.
The cooling fan 13 is the more axial-flow type cooling fans being set side by side.
The radiator 14 is rectangular ribbed.
The radiator base plate 14b has the one side 14c of fin, and the position in control cabinet 10 on depth direction is located at cold
But between the middle line 13b of fan 13 and the outer 13c of separate control cabinet rear plate side.
The synthesis drafting efficiency of air inlet 11a on the control cabinet front shroud 10a is 25%；The control cabinet front shroud
The synthesis drafting efficiency of air outlet 12a on 10a is 50%.
The installation site of the cooling fan 13 makes its fan outer 13a and control cabinet rear plate close to control cabinet rear plate side
The distance between 10b is no more than 5mm.
The installation site of the deflector 15 keeps it orthogonal with the outlet air surface of radiator fin 14a and cooling fan 13.
The power device 16 is made of rectifier bridge module, IPM module and attached printing forme.
After cold air outside the control cabinet 10 is sucked by the air inlet 11a of lower part, by cooling fan 13 by it through leading
Flowing plate 15 blows to radiator 14, after the heat that cold air absorption dynamometer part 16 is distributed becomes hot-air, by the outlet air on top
Control cabinet 10 is discharged in mouth 12b；Deflector 15 between cooling fan 13 and radiator 14 makes the gas being blown between radiator fin 14a
It flows more uniform.
What the present invention can achieve has the technical effect that
The present invention possesses independent air duct, the influence of other heater elements in uncontrolled cabinet；Air inlet of the invention and
Air outlet configures on control cabinet length direction in radiator two sides, is formed by the uncontrolled cabinet effect length in air duct, stroke
Short, air-flow frictional head loss is small；Deflector between fan and radiator of the invention can make the gas between radiator fin
Flow distribution is uniform；Therefore, the present invention can be realized more preferably heat dissipation effect.
In the case where being no more than the permission temperature rise of control cabinet and its internal components, the present invention can use the smaller radiator of volume
And the less fan of quantity, while reducing installation cost, the more conducively thin design of control cabinet.
The front that control cabinet is set into and out of air port of the invention keeps cabinet body unrestricted and arranges according to wall (wall),
It can even be placed at wall (wall) angle.So elevator obtains greater flexibility in civil engineering arrangement.
