Embodiment
As shown in Figure 2, the present invention includes blower fan 40, also comprise the collecting region 10, amplification region 20 and the output area 30 that communicate successively, collecting region 10 is arranged in the cabinet, a zone that communicates is formed in above-mentioned three layers of air channel, the major part of described blower fan 40 is positioned at this zone, described amplification region 20 perpendicular to the axial area of section of blower fan 40 big than collecting region 10.
The major part of blower fan is arranged in the zone that communicates of forming in collecting region 10, amplification region 20 and output area 30, has reduced the volume of cabinet on the whole, be beneficial to installation and maintenance.Adopt the design in three layers of air channel, the air channel length of the collecting region 10 that the cross section is less relatively diminishes, amplification region 20 bigger than the area of section of collecting region 10 perpendicular to the axial area of section of blower fan, wind is discharged through the output area then through expanding to the amplification region rapidly behind the collecting region like this, on the whole, shorten in the air channel, and windage diminishes, good heat dissipation effect.
Single relatively air channel, stratified like this air channel also is easy to dodge layout with other components and parts in cabinet, thereby has also reached the purpose that reduces the cabinet volume.Output area 30 is generally positioned at outside the cabinet, be more conducive to wind output like this, and amplification region 20 can be arranged at and also can be arranged at outside the cabinet in the cabinet, as preferred scheme, amplification region 20 is arranged in the cabinet, most of volume of blower fan 40 is hidden in rack inside like this, has reduced the volume of whole device, makes outward appearance more attractive in appearance.
Shown in Fig. 2,3,4, described collecting region 10 is a rectangular configuration, be provided with collecting region wind-collecting cover 11, one side of the close radiator of collecting region wind-collecting cover 11 is provided with some air inlets 12, amplification region wind-collecting cover 21 is fixed in the opposite side of collecting region wind-collecting cover 11, output area wind-collecting cover 31 is fixed in the opposite side of amplification region wind-collecting cover 21, and the rear end of blower fan 40 is fixed on the side away from amplification region 20 of output area wind-collecting cover 31.
Collecting region 10 is made as rectangular configuration, helps hygral equilibrium.Especially be applied to the occasion of photovoltaic/wind-force parallel network reverse device, help the hygral equilibrium between the three-phase module.
Shown in Fig. 2,3, this device also comprises baffle liner mounting panel 61, baffle liner mounting panel 61 is fixed on the collecting region 10, join with baffle liner 60, baffle liner 60 joins with the air inlet of blower fan 40, the major part of the air outlet of blower fan 40 is positioned at amplification region 20 and output area 30, amplification region 20 and output area 30 suitable perpendicular to the axial area of section of blower fan 40.
Baffle liner 60 is arranged at collecting region, helps the collection of wind, because of the cross-sectional area of amplification region 20 and output area 30 is bigger than the cross-sectional area of collecting region 10, so the major part at least of air outlet is arranged at the discharge that above-mentioned two zones more help wind.When blower fan carries the occasion of baffle liner, described baffle liner 60 can save.
Described blower fan 40 is that the back is to centrifugal blower.Described blower fan 40 can be selected various types for use, and for example axial flow blower etc. adopts the back to centrifugal blower as preferred version of the present invention.The back is little, in light weight to the centrifugal blower volume, power consumption is little, has saved the energy, but the air outlet four sides air-out, the rotating speed height of fan, air quantity is big, efficient is high.Adopt the back to centrifugal blower, can further reduce the cabinet volume, make radiating effect better.
Shown in Fig. 2,4, amplification region 20 be the trend of even increase perpendicular to blower fan 40 axial areas of section, can reduce the resistance of gas like this, be beneficial to the gas that blower fan 40 is screwed out and be forced into output area 30, and then discharge outside the cabinet.As preferred version of the present invention, the structure that wind-collecting cover 21 upper and lower surfaces in amplification region are designed to the inclined-plane increases the cross-sectional area of amplification region 20, and this mode is more conducive to the wind of amplification region is forced into the output area.
As shown in Figure 3, described three layers of air channel can be made as a plurality of, are provided with dividing plate 50 between each three layers of air channel.
When the present invention is a plurality of module heat dissipating, a plurality of three layers of air channel can be set, in order to prevent the phase mutual interference of heat between each module, between each three layers of air channel, dividing plate 50 is set, can form separation, air channel independently like this, avoid interference.
