The coaxial two-stage cross flow fan that axis is overlapped with internal lobe wheel axis.
Background technique
Common blower type has axial flow blower, cross flow fan, centrifugal blower in household appliances.Its typical application product
Example is respectively, using the vertical fan of axial flow blower, using the kitchen ventilator of centrifugal blower, using the air conditioner chamber of cross flow fan
Interior machine.The characteristics of axial flow blower is that flow is higher, pressure is lower, noise is larger.The structure of axial flow blower is simple.
The characteristics of cross flow fan is that moderate flow, moderate pressure, noise are smaller.Cross flow fan axial length is unrestricted,
Air outlet air-flow along cross flow fan axial distribution uniform.Compared with axial flow blower, the air-flow of cross flow fan runs through impeller
Air-flow can be transported to larger distance under low noise conditions by the effect of blade power twice by flowing, air-flow.Cross flow fan
Air-flow force to turn back in impeller, therefore the pressure loss is larger, efficiency is lower.Cross-flow fan impeller uses forward-type blade.
The characteristics of centrifugal blower is that flow is lower, pressure is higher, noise is smaller.The air inlet of centrifugal blower is along centrifugation wind

Fan efficiency is higher.Centrifugal blower fan blade wheel has forward-type blade, radial vane, backward type blade three types.
In conclusion the pressure of cross flow fan is up for improving, two-stage cross flow fan is a kind of technology option.Applied to combustion
For the axial-flow compressor of gas-turbine using multistage, every level-one axial-flow compressor includes that row's rotor blade and a subsequent row are quiet
Blades.Air-flow is accelerated by rotor blade first, then slows down in gap passage of the air-flow between stator blade, rotor leaf
The kinetic energy that piece passes to air-flow is converted into potential energy, which is repeated in the multistage blade of axial-flow compressor, Zhi Daozong
Until pressure ratio reaches requirement.Every level-one axial-flow compressor is compared with axial flow blower, more row's stator blades, rotor blade with
There is relative motion between stator blade, air-flow slows down pressurization in the gap passage between stator blade, makes every level-one axial-flow type
The stream pressure of compressor output is far longer than the stream pressure of axial flow blower output.If the air-flow of axial-flow compressor is existed
Slow down in gap passage between stator blade pressurization technology be applied to two-stage cross flow fan, then can be improved two-stage through-flow wind
The stream pressure of machine output.

The cross flow fan run when, air-flow from air inlet 16 enter air inlet Inner chamber 79, enter the wind Inner chamber 79 in air-flow according to
The secondary gap passage flowed through between the siphonal lobe impeller blade 39 of air inlet Inner chamber 79, and the internal lobe wheel blade close to air inlet Inner chamber 79
Gap passage between piece 43 enters inner impeller Inner chamber 78, and the air-flow in inner impeller Inner chamber 78 is flowed successively through close to spiral case Inner chamber 36
Internal lobe impeller blade 43 between gap passage, and close to spiral case Inner chamber 36 siphonal lobe impeller blade 39 between gap passage into
Enter spiral case Inner chamber 36, the air-flow in spiral case Inner chamber 36 is discharged along air outlet airflow direction 25 from air outlet 24.
When the cross flow fan is using two motors driving operation, i.e., when B-mode coaxial two-stage cross flow fan is run, electricity
Motivation one drives out rotor 2 to rotate along out rotor direction of rotation 80 by shaft 1, out rotor end plate 1.It is same with this
When, motor two drives inner impeller 3 to rotate along inner impeller direction of rotation 81 by shaft 29, inner impeller end plate 24.
When the cross flow fan is run, out rotor 2 rotates in the opposite direction with inner impeller 3.In air flow path 82, position
Accelerated first by the siphonal lobe impeller blade 39 close to air inlet Inner chamber 79 in the air-flow of air inlet Inner chamber 79, then air-flow is close to air inlet Inner
Slow down in gap passage between the internal lobe impeller blade 43 of chamber 79 and be pressurized, the kinetic energy that siphonal lobe impeller blade 39 passes to air-flow is changed
For potential energy, siphonal lobe impeller blade 39 and internal lobe impeller blade 43 carry out one stage of compression to air-flow.Air-flow positioned at air inlet Inner chamber 79 enters
Inner impeller Inner chamber 78.Air-flow in inner impeller Inner chamber 78 is accelerated by the internal lobe impeller blade 43 close to spiral case Inner chamber 36, then air-flow
Slow down in gap passage between the siphonal lobe impeller blade 39 close to spiral case Inner chamber 36 and be pressurized, internal lobe impeller blade 43 is passed to gas
The kinetic energy of stream is changed into potential energy, internal lobe impeller blade 43 and siphonal lobe impeller blade 39 and carries out two-stage compression to air-flow.Positioned at inner impeller Inner
The air-flow of chamber 78 enters spiral case Inner chamber 36.When the cross flow fan is run, air-flow passes through two stages of compression, and air-flow is successively by siphonal lobe
The effect of the power twice of impeller blade 39, and by the effect of the power twice of internal lobe impeller blade 43, improving 24 stream pressure of air outlet
While, also improve the working efficiency of the cross flow fan.When the cross flow fan is using two motors driving operation, respectively
The revolving speed for adjusting motor one and motor two, can be such that the cross flow fan runs under optimal parameter.
