In this way, as downward, the radial center of air-supply region is increasingly towards radial outside deviation.Especially sent at this
In wind apparatus 1, with downward and air-supply region gradually increases.Thus, it is quiet in axial gap 400 with downward
Pressure improves.
Downward by the air-flow of air entry 202 and multiple passages 60 in each axial gap 400 by radially
Outside attracts.Therefore, with being weakened by the air-flow of passage 60 downward.In the present embodiment, with
Just increase the air-supply region of each flat board 410, with the caused air-flow enhancing in axial gap 400 downward.Cause
This, the air-flow by passage 60 is attracted downwards.Thus, also supplied enough to the axial gap 400 for being configured at bottom
The gas of amount.As a result, more improve the air-supply efficiency in air supplying part 40.
In the impeller rotation for making to have multiple blades produces the conventional air-supply arrangement of air-flow, by caused by impeller
Air-flow leaks in the upper and lower end parts of impeller.Also, the axial length regardless of air-supply arrangement, it can all produce letting out for the air-flow
Leakage.Therefore, if being thinned air-supply arrangement, influence of the leakage in air-supply arrangement entirety can become big, therefore efficiency of blowing
Decline.On the other hand, in the air-supply arrangement 1 of present embodiment, because the near surface in flat board 410 produces air-flow, therefore
The air-flow is not easy to leak along above-below direction.Therefore, even in the situation for the axial length for reducing the air supplying part 40 for producing air-flow
Under, it is not easy to produce the decline of air-supply efficiency because of the leakage of air-flow.That is, even in the situation for being thinned air-supply arrangement 1
Under, it is not easy to cause efficiency decline of blowing.
Also, in the air-supply arrangement with impeller, produce and periodically make an uproar because of the shape of blade, piece number, configuration etc.
Sound.However, the air-supply arrangement 1 produces air-flow by the viscous drag and centrifugal force on the surface of flat board 410, thus with impeller
Air-supply arrangement compare, quietness is excellent.
In addition, in the air-supply arrangement 1, the respective external diameter of each flat board 410 is more than the outer of up adjacent flat board 410
Footpath.However, the external diameter of a part of flat board 410 can also be identical with the external diameter of up adjacent flat board 410.Even in this feelings
Under condition, as long as the external diameter of lower flat 412 is more than the external diameter of upside flat board 411, and the external diameter of a part of flat board 410 is more than
The external diameter of the adjacent flat board 410 in top, then can also obtain same effect.
Also, from the viewpoint of PQ characteristics (air volume-static pressure characteristic), compared with the air-supply arrangement with impeller, have
Static pressure of the air-supply arrangement 1 of multiple flat boards 410 in low air quantity region is big.Therefore, air-supply arrangement 1 is adapted to compare can only discharge
Used in high density housing of the air-supply arrangement with impeller than relatively low air quantity.As such housing, such as enumerate individual
