Fig. 1 is through-flow fan blade one example structure schematic diagram of the present invention;
Fig. 2 is the generalized section of Fig. 1;
Fig. 3 is the cross-sectional structure schematic diagram of Fig. 2 Leaf;
Wherein: 1 through-flow fan blade; 2 motors; 3 refrigerant inlets; 4 blades; 5 refrigerant outlets; 6 circulation passages; 7 rotating seals; 8 stiffening rings; 9 left dishes; 10 right dishes.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, through-flow fan blade of the present invention and air conditioner are further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1 to Figure 3, a kind of through-flow fan blade 1, through-flow fan blade 1 is in transmission connection with motor 2, and rotate under the driving of motor 2, through-flow fan blade 1 comprises blade 4, and circulation passage 6 is set on blade 4, refrigeration agent flows through in circulation passage 6, and by blade 4 and blade 4 surface dielectric heat exchange.
By circulation passage 6 is set on blade 4, and refrigeration agent flows through in circulation passage 6, motor 2 drive vane 4 rotations, make the speed of medium on blade 4 surfaces very large, well with circulation passage 6 in refrigeration agent carry out heat exchange, so not only simple in structure, with low cost but also heat exchange efficiency is high.
The material of blade 4 can be metal, because metal is hot good conductor, the material of blade 4 be metal can make the medium on blade 4 surfaces can be better with circulation passage 6 in refrigeration agent carry out heat exchange, make heat exchange efficiency become higher.
As a kind of embodiment, also comprise refrigerant inlet 3, refrigerant outlet 5 and rotating seal 7, refrigerant inlet 3 and refrigerant outlet 5 are all communicated with circulation passage 6 by rotating seal 7.
Because blade 4 rotates, refrigerant inlet 3 and refrigerant outlet 5 are all communicated with circulation passage 6 by rotating seal 7, the sealability of the rotation junction plane that can improve circulation passage 6 respectively and between refrigerant inlet 3 and refrigerant outlet 5, avoids the leakage of refrigeration agent.
As a kind of embodiment, the quantity of circulation passage 6 is two or more.Can increase like this heat exchange area of refrigeration agent in circulation passage 6, heat exchange efficiency is protected.
As a kind of embodiment, the shape of the shape of circulation passage 6 and blade 4 is suitable.The sectional shape of circulation passage 6 can be the shapes such as square, circular, semicircle, oval, trapezoidal, triangle, annular, also can be above-mentioned difform combination, the shape of circulation passage 6 and the shape of blade are suitable, be that circulation passage 6 can be made according to the shape of blade 4, can increase the sectional area of circulation passage 6, can guarantee under the prerequisite of refrigerant flow like this, reduce the rotating speed of blade 4, reduce noise.
As a kind of embodiment, the quantity of blade 4 is 2 to 100, and is circumference.The quantity of blade 4 is 2 to 100, can be arranged on same circumference, can guarantee like this dynamic balancing of through-flow fan blade 1 in rotation, thereby guarantees operational effect.
As a kind of embodiment, also comprise stiffening ring 8, stiffening ring 8 is sleeved on blade 4, and is fixedly connected with blade 4.Can make like this blade 4 more be fixedly mounted on through-flow fan blade 1, thus the stability of blade 4 while having guaranteed through-flow fan blade 1 operation.
As a kind of embodiment, the quantity of stiffening ring 8 is two or more.
As a kind of embodiment, also comprise left dish 9 and right dish 10, blade 4 is fixedly connected with right dish 10 with left dish 9 respectively.So not only can make the installation of blade 4 more firm, can also guarantee the reliability that circulation passage 6 is communicated with refrigerant inlet 3 and refrigerant outlet 5 respectively simultaneously.
For realizing the object of the invention, a kind of air conditioner is also provided, comprise the through-flow fan blade of above any embodiment.
Through-flow fan blade in air conditioner of the present invention, identical with above-mentioned through-flow fan blade, and realize with identical technological scheme, therefore, in the present embodiment, no longer the through-flow fan blade in air conditioner is described in detail one by one.
