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
