On reduce space needed for whole machine installation, effectively control fan blade and spiral case gap, improve wind speed and pressure.Further, due to
Acceleration portion uses linear smooth side wall and causes, and the gap of acceleration portion side wall and centrifugation blade reduces, therefore by centrifugation blade
Fan blade center with respect to spiral case air inlet center far from acceleration portion eccentric setting, to compensate for the flow of fan outlet, increase
Add wind speed.In summary structure, which reduces space needed for whole machine installation, and wind speed and pressure is improved in performance.
Description of the drawings
Fig. 1 is the side structure schematic diagram of the utility model.
Fig. 2 is the dimensional structure diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings, the preferred embodiment of the utility model is described in further detail.
A kind of modified coiler fan as shown in Figure 1 and 2, including spiral case 1, and setting is in 1 inside of spiral case and by motor
The centrifugation blade 2 driven；There is air inlet 11 on 1 side of the spiral case, 1 end of spiral case is equipped with air outlet 12, inside spiral case 1
Air inlet 11 is constituted to the air duct of air outlet 12.
12 upstream end of air outlet of the spiral case 1 be acceleration portion 13, the spiral case side wall in acceleration portion 13, and with the acceleration
The spiral case side wall of portion 13 diametrically is linear smooth side wall 14.The air inlet 11 in spiral case 1 is arranged in the centrifugation blade 2
Interior, centrifugation blade 2 includes bottom plate 21, and is fixed on multiple blades 22 on 21 end face of bottom plate along 21 circumferential edge of bottom plate.Institute
It is axial corresponding with the air inlet 11 of spiral case 1 to state bottom plate 21, multiple blades 22 are along the circumferential regular arrangement of air inlet 11.The centrifugation wind
The fan blade center of leaf 2 with respect to spiral case 1 11 center of air inlet far from 13 eccentric setting of acceleration portion, eccentric distance is 1 diameter of spiral case
5% ~ 7%.1 diameter of the spiral case is 150mm, and the eccentric distance at fan blade center is 8 ~ 10mm, linear smooth side wall 14 and spiral case 1
The maximum distance of the outer circumference at place is 8 ~ 12mm.12 upstream end of air outlet in the coiler fan is acceleration portion 13, and
By the spiral case side wall in acceleration portion 13 in the program, and it is disposed as linearly with the spiral case side wall of the acceleration portion 13 diametrically
Smooth side wall 14, the setting compared to traditional arc-shaped side wall, the linear smooth side wall 14 reduce whole machine installation on the whole
Required space effectively controls the gap of fan blade and spiral case 1, improves wind speed and pressure.Further, since acceleration portion 13 uses line
Mild-natured whole side wall 14 and cause, the gap of 13 side wall of acceleration portion and centrifugation blade 2 reduces, therefore will be in the fan blade of centrifugation blade 2
The heart with respect to spiral case 1 11 center of air inlet far from 13 eccentric setting of acceleration portion, to compensate for the flow of fan outlet 12, increase
Wind speed.In summary structure, space needed for the whole machine installation which reduces, and improves wind speed and pressure in performance.
The spiral case side wall of the air outlet 12 extends along air-out direction is equipped with outlet section 15, the upper edge side wall 16 of outlet section 15
