The inclined direction of plate 1262 is consistent.
Further, cowling panel 1264 is smoothly connected with centrifugation plate 1262 so that centrifugal step 1282 and rectification section 1284 it
Between smoothly transition from, contribute to reduce resistance, reduce windage loss, to increase the air quantity of blower fan apparatus 10.
In some embodiments, centrifugation plate 1262 is parallel to the central axis X of wheel hub 122, the bottom of cowling panel 1264
It is bent towards the direction opposite with centrifugation 1262 inclined direction of plate so that the flow direction of the air-flow flowed out from centrifugal step 1282 is whole
It is diverted under the action of flowing plate 1264 and wheel disc 124 consistent with flow direction when air-flow inflow stream entrance 1242.
In this way, make air-flow in centrifugal step 1282 by preferably CENTRIFUGAL ACCELERATING, and the air-flow that will be flowed out from centrifugal step 1282
It is turned in rectification section 1284.
Specifically, it can also be curved slab that centrifugation plate 1262, which can be surface plate, bent when it is curved slab to centrifuge plate 1262
The axis parallel of the busbar and wheel hub 122 of panel.In the utility model embodiment, centrifugation plate 1262 is surface plate, such as Fig. 4
And shown in Fig. 5, blade 126 is divided into centrifugation plate 1262 and cowling panel 1264 along AB.
