Description
Technical field
The present invention relates to electrification to control, more particularly to a kind of switch board.
Background technology
With the development of economy and society, frequency converter is widely used in all trades and professions as a kind of energy-saving equipment, and not
Of the same trade and requirement of the different application field to frequency converter use environment is also inconsistent.As mine industry requires that frequency converter can be in ash
Dirt assemble and the stronger environment of corrosivity in use, air conditioner industry requires that frequency converter can make in the rainy environment of more dirt out of doors
With.Severe and changeable use environment requires frequency converter both with dust reduction capability again with water-proof function, and this requires frequency conversion
The degree of protection system of device or switch board can reach more than IP44 degree of protection.Degree of protection (INGRESS PROTECTION,
Referred to as " IP ") it is made up of (such as two numerals：IP ××s classification standard), the 1st numeral represents solid protective grade, prevents
The grade of the foreign objects such as dust intrusion, the 2nd numeral represent liquid-state protective grade, are blocks moisture, the tightness of waterproof intrusion, count
Word is bigger to represent that its degree of protection is higher；For example, IP44 degree of protection represents：First 4 expression, prevent diameter more than 1mm's
Line or tablet or diameter exceed 1mm solid；Second 4 expression, splashproof or any direction dabble should be without adverse effect.
Frequency converter or switch board are while IP44 degree of protection is reached, it is also necessary to the radiating of frequency converter or switch board
It is stable performance, reliable.Inventor has found that at least there are the following problems in the prior art：Entering in the frequency-conversion control cabinet used at present
Air outlet employs interior outer double-layer structure, wherein, it is interlayer cavity among bilayer, this structure one side windage is big, is unfavorable for
Radiating, it on the other hand can not reach IP44 high-protection level.Some frequency converters use layered shaping, and radiator layer is not done
Protection, and use the radiator fan of IP44 degree of protection；Electronic component layer is designed using airtight cavity, but in airtight cavity
Component temperature rise it is higher, it is unfavorable to the life-span.Some switch boards employ the processing of high-protection level, still, frequency converter work
When the hot blast of frequency converter unit is exhausted directly in switch board, influence the service life of other components cabinet Nei.
The content of the invention
It is an object of the invention to provide a kind of switch board so that switch board both has high-grade protection, and and can is realized
Stable heat dispersion, so as to improve the service life of switch board.
In order to solve the above technical problems, embodiments of the present invention provide a kind of switch board, including：Cabinet and frequency converter
Unit；Cabinet includes cabinet body and cabinet door, and the front portion of the cabinet body is detachably connected with the cabinet door, the back of the body of the cabinet body

Demarcation strip 204, rectification heat-sink unit 205, inversion heat-sink unit 206 and electrochemical capacitor unit 207 are arranged on frequency conversion
In the housing of device unit 20；Demarcation strip 204 is used to place space in the housing of frequency converter unit 20 being divided into frequency converter unit
Front end area 208 and frequency converter unit back-end region 209, frequency converter unit front end area 208 place electrochemical capacitor unit 207,
Frequency converter unit back-end region 209 places rectification heat-sink unit 205, inversion heat-sink unit 206, and the He of rectification heat-sink unit 205
Inversion heat-sink unit 206 is fixed on demarcation strip 204.
Specifically, demarcation strip 204 should have athermanous characteristic, prevent that rectification heat-sink unit 205, inversion radiating are single
The heat that member 206 distributes influences electrochemical capacitor unit.When frequency converter unit 20 is normally placed in cabinet body 101, separate
Place space in the housing of frequency converter unit 20 is divided into former and later two regions by plate 204, in frequency converter unit front end area 208
Electrochemical capacitor unit 207 is inside placed, as shown in Figure 9.Wherein electrochemical capacitor unit 207 includes：Electrochemical capacitor and electrolysis
Capacitance bracket, electrochemical capacitor are arranged on electrochemical capacitor support.Rectification heat-sink unit 205 includes：Rectification unit and radiator, it is whole
Flow unit installation on a heat sink, radiator is fixed on demarcation strip 204.Inversion heat-sink unit 206 includes：Inversion unit and dissipate
Hot device, inversion unit are installed on a heat sink, and radiator is fixed on demarcation strip 204.
In one possible embodiment, the housing bottom of frequency converter unit 20 sets the first ventilating opening 2021 and second logical
Air port 2022；First ventilating opening 2021 is located at frequency converter unit front end area 208, and the second ventilating opening 2022 is located at frequency converter unit
Back-end region 209.
Specifically, the first ventilating opening 2021 and the second ventilating opening 2022 are separated by demarcation strip 204, logical by first
The air intake of air port 2021 is used cooperatively with the first fan 201, contributes to the device positioned at frequency converter unit front end area to radiate；Pass through
The air intake of second ventilating opening 2022, it is used cooperatively with the first fan 201, contributes to the device positioned at frequency converter unit back-end region to dissipate
Heat.As shown in Figure 9, Fig. 9 overlooks for the bottom of frequency converter unit 20 for the position of first ventilating opening 2021 and the second ventilating opening 2022
Figure.The reasonable disposition of air quantity is realized by the first ventilating opening 2021 and the second ventilating opening 2022.
It is noted that frequency converter unit 20 also includes：Reactor 230；Before reactor 230 is placed on frequency converter unit
End regions 208, and the first ventilating opening of face 2021.Reactor 230 can also produce heat, and reactor 230 is placed on into frequency converter
Unit front end area 208.The process of radiating is in frequency converter：First ventilating opening 2021 and the second ventilating opening 2022 difference air intake,
First fan is arranged on the top position of the back surfaces in the housing of frequency converter unit 20, by the first fan, drives wind
Flowing, so as to realize the radiating to frequency converter front end area 208 and frequency converter back-end region 209.
The switch board provided in present embodiment, by setting demarcation strip, isolation rectification radiating list in frequency converter unit
The heat that member and inversion heat-sink unit distribute, avoiding the heat that rectification heat-sink unit and inversion heat-sink unit distribute makes electrolysis electric
Hold the electrochemical capacitor temperature rise in unit, so as to improve the service life of electrochemical capacitor unit.In addition, rectification heat-sink unit
It is separately positioned with inversion heat-sink unit, the direct superposition between inversion unit and rectification unit caloric value is avoided, influences to radiate
Effect.Coordinate the first ventilating opening and the second ventilating opening simultaneously, realize the reasonable disposition of air quantity；Further, since frequency converter unit
For main heat-sink unit, radiating effect is high, and heat caused by reactor is far smaller than rectification unit and inversion unit production
Raw heat, therefore, reactor is directly placed in frequency converter unit, effectively can be filled using the radiating of frequency converter unit
Put, improve the radiating effect of whole switch board.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific embodiment of the present invention,
And in actual applications, can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
