From figs. 3 and 4 it can be seen that the inner side that the upper part in front storehouse 1 is positioned at upper left door cover plate 7 is additionally provided with one for installing the inner plating 9 of pcb board, inner plating 9 panel is provided with the air inlet leading to front storehouse by apical position. The left side of inner plating 9 is provided with a boss, and boss surface is connected with casing by hinge, upper left door cover plate 7 pass on left the position of close boss on the left of the inner plating 9 being hingedly coupled to, leave one end distance between inner plating 9 and upper left door cover plate 7. The left side of inner plating 9 and the right side of upper right door cover plate 8 are connected with casing respectively through hinge so that it is all can hinge through around this.
In the present embodiment, the air inlet on front door 5 is provided with ventilation filter assembly, and bottom cabinet, the air inlet of surrounding is provided with fly net, and the Rear Door of cabinet is provided with the air inlet leading to rear storehouse. The upper plate body 31 of interlayer 3, middle plate body 32, lower body 33 adopt panel beating to make.
Below in conjunction with accompanying drawing, the radiating mode of this cabinet is elaborated:
First being provided with the electronic devices and components such as direct current branch switch, direct current main switch, alternating-current switch, copper bar, binding post, miniature circuit breaker, communication lightning-protection device, DC lightning prevention device in the bottom in the front storehouse 1 of cabinet, upper space is provided with wire capacitance, wire capacitance copper bar and IGBT power tube; After cabinet in storehouse 2, the electronic devices and components such as reactor, ac capacitor, catalyst, copper bar are installed.
In front storehouse 1, after the first fan group 10 is opened, the air in front storehouse is carried out convulsion by the first fan group 10, and outside air enters from the air inlet front door 5, most air can enter in front storehouse 1 lower space of cabinet through baffle plate 6, to the cooling electronic component that bottom, front storehouse 1 is installed. Extremely least a portion of air can be entered top, front storehouse 1 by left and right upper door cover plate 7,8, and the air inlet of upper right door cover plate 8 is in upside, and air can dispel the heat directly to the bus capacitor top that top, front storehouse 1 is installed after entering; Due in the present embodiment, the inner side of upper left door cover plate 7 is also equipped with inner plating 9, air is after the air inlet on the downside of upper left door cover plate 7 enters, flow through inner plating 9 surface, dispel the heat to the pcb board installed on it, entered top, front storehouse 1 by the air inlet on the upside of inner plating 9 again, dispel the heat to the bus capacitor top installed.
In front storehouse 1, the panel of the upper plate body 31 of interlayer, installing plate and cabinet both sides surrounds the first heat dissipation wind channel, the cooling electronic component amount installed due to bottom, front storehouse 1 is extremely low, by bottom, front storehouse 1 enter air themperature promote negligible, by the first fan group 10, air is pumped in the first heat dissipation wind channel again, it is positioned at, by the first heat dissipation wind channel, the louvre 11 that cabinet top board is provided with to discharge, thus dispelling the heat to the IGBT power tube being arranged on fixing plate 4 in air channel. Due to the blast that the first fan group 10 convulsion produces, flowing to the top, front storehouse 1 air after bus capacitor dispels the heat can flow as the first fan group 10, with bottom, front storehouse 1 enter air converge and sent in the first heat dissipation wind channel by the first fan group 10.
In rear storehouse 2, interlayer 2, the both sides panel of cabinet and rear board surround the louvre that the second heat dissipation wind channel, chassis backplane and bottom surrounding sidewall arrange and constitute the air inlet of this second heat dissipation wind channel, and the second fan group 20 that top board is installed constitutes air outlet. After the second fan group 20 starts, air in rear storehouse 2 is retracted to outside cabinet through the second fan group 20 being arranged on cabinet top board, rear storehouse 2 produces pressure, after outside air enters from the air inlet 22 surrounding sidewall bottom cabinet, it is provided with in the rear storehouse 2 that air inlet 21 enters cabinet by chassis backplane again, the air inlet 21 that air is provided with from chassis backplane flows to the second fan group 20 being arranged on cabinet top board straight, and the heat distributed by electronic devices and components takes cabinet out of.
After the middle plate body 32 of interlayer 3 adopts inclined design, be conducive to air flowing in this second heat dissipation wind channel, it is to avoid because of horizontally disposed the phenomenon producing backflow.
The present invention compared with prior art, it is an advantage of the current invention that:
One, double; two air duct radiation is adopted, reactor, transformator and IGBT power tube are in independent air channel, heat radiation independently, so that the temperature at the fast IGBT place of reactor, transformator and power mould greatly reduces, thus improving its efficiency, extend the service life of machine, the life-span of fan also can be made to be greatly improved simultaneously, reduce the cost of fan.
Two, simple in construction, easy to maintenance.
Three, Qian Cang and rear storehouse are independent of one another, and when reducing IGBT power tube aircraft bombing, its fragment can cause the risk that reactor, transformer secondary explode.
Four, Qian Cang and rear storehouse shield completely, sine wave that reactor produces and the rectangular wave that IGBT produces can be made mutually to shield, will not influence each other, the performance of machine can be made to improve.
Five, the Duct design in this cabinet, can effectively give the heat radiations such as the pcb plate of control chamber, the power module of power supply, bus capacitor, switch, bus bar copper row, copper bar, make machine efficiency and performance be greatly improved.
Six, adopting double duct system, transformator, reactor air channel adopt from bottom surrounding air intake; IGBT constant power module adopts from above air intake. Like this, the dust of interior of equipment cabinet will being made greatly to reduce, reduce some risks, and windage is protected, improving the heat radiation of machine, thus improving performance and the efficiency of machine. Be far longer than (PCC) power and circuit board due to the ability of reactor and transformator anti-dust, so can do dust guard to respectively the air inlet in storehouse, front and back, or only the air inlet on front panel does dust guard.
