The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention is described.
As shown in Figure 1-Figure 3, the fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention, comprising: the first wind
Take turns the 21, second wind wheel 22 and driving assembly 3.
Wherein, the first wind wheel 21 includes multiple the first blades 211 being spaced apart in its circumferential direction, the second wind wheel 22
Including multiple the second blades 221 being spaced apart in its circumferential direction.On the circulating direction of air draught, the second wind wheel 22
The downstream of the first wind wheel 21 can be located at and the second wind wheel 22 can be spaced with the first wind wheel 21 and be arranged.Driving assembly 3 can divide
Do not cooperate with the first wind wheel 21 and the second wind wheel 22 to drive the first wind wheel 21 and the second wind wheel 22 to rotate.
Specifically, since the first wind wheel 21 and the second wind wheel 22 can be oppositely arranged on the direction of airflow, the
One wind wheel 21 and the second wind wheel 22 can organize pairs of whirlwind wheel, and the first wind wheel 21 and the second wind wheel 22 all can be axial-flow windwheels.
When fan assembly 2 works, driving assembly 3 can respectively drive the first wind wheel 21 and the rotation of the second wind wheel 22, the first wind wheel 21
Direction of rotation with the second wind wheel 22 can be opposite.The air-flow circumference of the blade exit of multiple first blades 211 is tangentially fast as a result,
It spends opposite with the air-flow circumference tangential velocity of blade exit of multiple second blades 221 and can partly or entirely cancel out each other,
It is hereby achieved that the straight air-flow of approximate pure " axial direction ", i.e., most of or even whole air draughts can be along fan assembly 2
Axial direction blowout, it is possible thereby to increase the air output and air supplying distance of fan assembly 2, and then can promote fan assembly 2
Air supply efficiency.
It is understood that compared to single tubular wine wheel, axial-flow windwheel or oblique flow wind wheel, to first in whirlwind wheel
Wind wheel 21 and the second wind wheel 22 can rotate simultaneously, it is possible thereby under the premise of driving assembly 3 consumes identical power, to whirlwind
Air output maximum, the air supply efficiency highest of wheel.Therefore, under the premise of meeting identical air output requirement, to the consumption of whirlwind wheel
Electricity is also minimum.Therefore, the fan assembly 2 in the present invention has the advantages that low energy consumption, greatly improves the practical of fan assembly 2
Performance.
Wherein, the rotating ratio between the first wind wheel 21 and the second wind wheel 22 can be 0.8~1.25.Specifically, working as wind
When being equipped in thermomechanical components 2 to whirlwind wheel, the operating noise that fan assembly 2 generates, which depends primarily on, generates the maximum wind wheel of noise.
Moreover, the revolving speed of noise level and the first wind wheel 21 and the second wind wheel 22 that fan assembly 2 generates is positive correlation.When first
When rotating ratio between wind wheel 21 and the second wind wheel 22 is 0.8~1.25, the revolving speed between the first wind wheel 21 and the second wind wheel 22
Difference is smaller, the equal very little of noise that the first wind wheel 21 and the second wind wheel 22 generate at this time, and the work noise of fan assembly 2 is the at this time
Noise that one wind wheel 21 and the second wind wheel 22 generate and.Conversely, when the rotating ratio between the first wind wheel 21 and the second wind wheel 22 is small
In 0.8 or be greater than 1.25 when, the rotational speed difference between the first wind wheel 21 and the second wind wheel 22 is larger, at this time the first wind wheel 21 and second
The biggish wind wheel of revolving speed in wind wheel 22 can become main noise source and generate very big noise, and fan assembly 2 generates at this time
Noise depend mainly on the size of dominant noise source generation noise.Therefore, the premise of identical air quantity is generated in fan assembly 2
Under, the noise that the rotational speed difference between the first wind wheel 21 and the second wind wheel 22 generates when larger is far longer than the first wind wheel 21 and second
The noise that 22 rotational speed difference of wind wheel generates when smaller.Pass through the rotating ratio between the first wind wheel 21 of control and the second wind wheel 22 as a result,
It is 0.8~1.25, the noise of the generation of fan assembly 2 can be substantially reduced, the usage comfort of user can be promoted.
The fan assembly 2 of air-conditioner outdoor unit 100 according to an embodiment of the present invention, by being arranged in air draught circulating direction
On the first wind wheel 21 and the second wind wheel 22 that are spaced apart, the air supply efficiency of fan assembly 2 can be promoted, so as to reduce energy
Consumption, greatly improves the practical performance of fan assembly 2.It is by the rotating ratio between the first wind wheel 21 of control and the second wind wheel 22
0.8~1.25, the noise of the generation of fan assembly 2 can be substantially reduced, so as to promote the usage comfort of user.
According to some embodiments of the present invention, the rotating ratio between the first wind wheel 21 and the second wind wheel 22 can for 0.9~
1.1, it is possible thereby to the rotational speed difference between the first wind wheel 21 and the second wind wheel 22 be further reduced, so as to further decrease wind
The noise that thermomechanical components 2 generate.Optionally, the rotating ratio between the first wind wheel 21 and the second wind wheel 22 can be 1.0, i.e. the first wind
Wheel 21 is identical with the revolving speed of the second wind wheel 22, and thus the first wind wheel 21 and the second wind wheel 22 can keep rotating at the same speed, Ke Yi great
The big work noise for reducing fan assembly 2.
As shown in Fig. 2, according to some embodiments of the present invention, the first wind wheel 21 is along its axial direction (before as shown in Figure 2
Rear direction) development length can be L1, the second wind wheel 22 can be L along the development length of its axial direction2, the first wind wheel 21
With the spacing L between the second wind wheel 220It can satisfy relational expression: 0.2 (L1+L2)≤L0≤1.5(L1+L2).Specifically, working as wind
When thermomechanical components 2 are rotated, whirlpool is revealed since rotation swing flap will form leaf top in the tail portion of the first blade 211 and the second blade 221,
Wherein the tail portion of the first blade 211 can be understood as the part close to the second blade 221 of the first blade 211, the second blade 221
Tail portion can be understood as part of second blade 221 far from the first blade 211.Reveal whirlpool in the leaf top that first blade 211 generates
By that can collide with the second blade 221 when the second wind wheel 22, bigger noise thus can be generated.
It is understood that working as L00.2 (L of <1+L2) when, the spacing between the first wind wheel 21 and the second wind wheel 22 is smaller,
Leaf top leakage whirlpool can be circulated to the second wind wheel 22 after generating in a short period of time, thus act on the second blade 221
Impact force is larger, to generate biggish noise.Work as L01.5 (L of >1+L2) when, between the first wind wheel 21 and the second wind wheel 22
Spacing is excessive, and the velocity of liquid assets loss for the air-flow that the first wind wheel 21 generates is larger, to reduce the air-supply effect of fan assembly 2
Rate.As 0.2 (L1+L2)≤L0≤1.5(L1+L2), the spacing setting between the first wind wheel 21 and the second wind wheel 22 is more reasonable, the
The intensity in the leaf top leakage whirlpool that one blade 211 generates can reduce during being circulated to the second wind wheel 22 from the first wind wheel 21,
It is possible thereby to reduce the impact force acted on the second blade 221, the noise of the generation of fan assembly 2 can be reduced.Moreover, at this time
Spacing between first wind wheel 21 and the second wind wheel 22 is smaller on the influence of the air supply velocity of fan assembly 2, so as to ensure wind
The air supply efficiency of thermomechanical components 2.
In specific example as shown in fig. 8, the development length L along its axial direction of the first wind wheel 211=60mm, the
The development length L along its axial direction of two wind wheels 222=40mm is controlled respectively between the first wind wheel 21 and the second wind wheel 22
Spacing size (L0=20mm, L0=30mm, L0=40mm) and detect the noise content that fan assembly 2 generates under different spacing.From
In chart shown in fig. 8 as can be seen that under the premise of fan assembly 2 generates identical air quantity, L0=20mm, that is, L0=0.2
(L1+L2) when the noise that generates of fan assembly 2 it is maximum, L0=30mm, that is, L0=0.3 (L1+L2) when fan assembly 2 generate noise
Compared to L0=0.2 (L1+L2) when the noise that generates have and significantly reduce, lower noise about 2.0dB (A).L0=40mm, that is, L0
=0.4 (L1+L2) when the noise that generates of fan assembly 2 it is minimum, L0=0.3 (L1+L2) arrive L0=0.4 (L1+L2) between noise drop
Low amplitude is far smaller than L0=0.2 (L1+L2) arrive L0=0.3 (L1+L2) between lower noise amplitude.
