Description of drawings
The structural representation of the rectifier cabinet installing rack that Fig. 1 provides for the utility model one embodiment;
Fig. 2 is the plan structure schematic diagram of the base portion of bellows in Fig. 1;
The structural representation of a kind of bellows that Fig. 3 provides for the utility model one embodiment.
Embodiment
The structural representation of a kind of bellows that Fig. 3 provides for the utility model one embodiment, as shown in Figure 3, the utility model embodiment provides a kind of bellows 3, bellows 3 are the cuboid box body structure of hollow, the end face of bellows 3 is provided with air intake vent 31, and air intake vent 31 is used for being connected to the bottom heat radiation mouth of rectifier cabinet; First side 41 adjacent with end face on bellows 3 also is provided with air outlet 32, and air outlet 32 is used for being connected to the air draft pipe of ventilation blower; Be provided with arc wind waveguide plate 33 between the bottom surface of the second side 42 relative with the first side 41 and bellows 3 in bellows 3, the arc of arc wind waveguide plate 33 pushes up the base between the second side 42 and bottom surface.
This arc wind waveguide plate 33 can carry out guide effect to the air-flow in bellows 3, make bellows 3 identical with bending bellows function of the prior art, but compare straight line, the bellows that the present embodiment provides are made simpler and easy, only need to fix an arc wind waveguide plate 33 in bellows 3 inside of cuboid gets final product, concrete can be by welding, and clamping is fixed on arc wind waveguide plate 33 by fixed connecting piece perhaps that bellows 3 are inner to be got final product.Can be a flat board for arc wind waveguide plate 33, it is bent into arc gets final product in bellows 3.
Compare with bellows of the prior art, in conjunction with shown in Figure 2, it is large that the bellows 21 of this kind shape of the prior art take volume, as shown in Figure 2, the bellows 21 of this kind bending type are owing to being the bending formation, so its thickness is with highly basic identical, bellows 21 are blocked up, the volume of bellows 21 is large, thereby causes air channel 2 volumes large, further causes the volume of rectifier cabinet integral body to increase.In addition, as shown in fig. 1, air channel 2 also comprises the exhaust passage that enters the air channel and be connected with the air outlet of bellows 21 that is connected with the air intake vent of bellows 21, and the other end that enters the air channel is used for being connected with the bottom heat radiation mouth of rectifier cabinet, and the other end of exhaust passage is used for being connected with the air draft pipe of ventilation blower.The inlet air road specifically comprises the flexible pipe air channel 22 that is connected with the air intake vent of bellows 21, and the other end in flexible pipe air channel 22 connects the slope air course 23 of inverted trapezoidal platform structure, and slope air course 23 is used for being connected with the bottom heat radiation mouth of rectifier cabinet.Be fixed by circular, hoop between flexible pipe air channel 22 and bellows 21, and be fixed by square hoop between flexible pipe air channel 22 and slope air course 23.The square air vent hole of slope air course 23 other ends and the bottom heat radiation mouth of rectifier cabinet coupling.Said structure is complicated, and is bulky, causes rectifier cabinet installing rack volume excessive.And the bellows 3 in the present embodiment, by adding arc wind waveguide plate 33 in the casing bottom, its thickness bellows 21 overall dimensions of can comparing reduce greatly, have omitted simultaneously the exhaust passage and entered the air channel volume to reduce greatly.
Preferred as technique scheme, the fillet between the second side 42 and arc wind waveguide plate 33 is positioned at the middle part of the second side 42.For guaranteeing good ventilation effect, and make the size of final bellows 3 less, select the fillet between arc wind waveguide plate 33 and the second side 42 is arranged on the middle part of the second side 42.
The air quantity that needs under particular job situation due to ventilation blower is for certain, and the heat that rectifier cabinet produces under the low-power consumption operating state is few, can not be fully and the operating state of ventilation blower be complementary, so in order to satisfy the work requirements of ventilation blower in the course of work, also be provided with on the second side 42 for the volume adjusting apparatus of regulating bellows 3 interior air forces, volume adjusting apparatus is positioned at the top of the connecting portion of the second side 42 and arc wind waveguide plate 33, and volume adjusting apparatus is not shown in the accompanying drawings.The bellows structure that the present embodiment provides is simple, and ventilation quantity is adjustable.
Preferred as technique scheme, volume adjusting apparatus is sieve plate or a plurality of by-pass prot.For the demand of different ventilation blower air quantity, to sieve plate or by-pass prot is blocked or open, can reach the purpose of regulating bellows 3 whole ventilation quantitys.
The another embodiment of the utility model also provides a kind of rectifier cabinet installing rack, installing rack comprises as the bellows in above-mentioned embodiment, installing rack also comprises the bracing frame of frame structure, and bracing frame is positioned at rectifying cabinet air channel top, and the air intake vent top of height and bellows 3 adapts.Because the overall volume of bellows 3 diminishes, the overall volume in air channel reduces accordingly, and bracing frame is above the air channel, and overall width and bellows have substantial connection, the volume-diminished of bellows, the volume of bracing frame also can reduce accordingly.The rectifier cabinet installing rack that the present embodiment provides is fully saved installing space, is convenient to assembling and adjusts.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
