Abstract
The invention relates to the technical field of an air conditioner, and discloses an axial-flow fan blade of a double-blade structure. The axial-flow fan blade comprises an inner circle of fan blade and an outer circle of fan blade, and the diameter of the inner circle of fan blade is smaller than that of the outer circle of fan blade; the blade number of the inner circle of fan blade is smaller than that of the outer circle of fan blade. The invention also discloses an air conditioner outdoor machine utilizing the axial-flow fan blade. The airflow in different intensity is produced through two complicated structural fan blades, so that air pressure difference is formed, the air can be concentrated in front of the fan blades and then be dispersed, and a purpose of increasing the air supply amount can be realized; the heat exchanging effect of an outdoor heat exchanger is better, and not only can more efficient energy conservation of the air conditioner system be realized, but also the noise of the outdoor machine can be lowered.
Description
Technical field
The present invention relates to air-conditioner technical field, particularly a kind of dual blade structure axial-flow leaf and apply the air-conditioner outdoor unit of this axial-flow leaf.
Background technology
See accompanying drawing 3, the air-conditioner used in household room and in working environment, the axial-flow leaf of its off-premises station is substantially all substance structure, generally there are 2,3 or 4 fan blades, wind inside during running is very weak, and crosswind is stronger more outward, and linearly blows out, can be formed like this and comprise swirl component " mechanical blowing ", cause noise larger.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above, a kind of air conditioner outdoor machine axial-flow leaf of dual blade structure is provided, producing the different air-flow of intensity by the fan blade of the double labyrinth of size makes air form draught head, strengthen the wind inside fan blade, thus spread blowout again after wind can be made to concentrate before fan blade, reach the object strengthening air output, make outdoor heat exchanger heat transfer effect better, not only realize the more energy-efficient of air-conditioning system, and off-premises station noise can also be reduced.
To achieve these goals, the invention provides following technical scheme:
An axial-flow leaf for dual blade structure, is characterized in that, described axial-flow leaf comprises inner ring fan blade and outer ring fan blade double structure, and described inner ring fan blade diameter is less than described outer ring fan blade diameter; The fan blade number of described inner ring fan blade is less than the fan blade number of described outer ring fan blade.
Further, described inner ring fan blade is 2, and described outer ring fan blade is 3 or 4.
Further, described inner ring fan blade is 3, and described outer ring fan blade is 4 or 5.
Further, described inner ring fan blade is 1: 2 with the diameter ratio of outer ring fan blade.
Further, the material of described axial-flow leaf can be the compound of plastics and glass.
Apply an air-conditioner outdoor unit for above-mentioned axial-flow leaf, it is characterized in that, comprise outdoor motor, described axial-flow leaf is arranged on described outdoor motor by the axle sleeve in described axial-flow leaf, drives running by described outdoor motor.
Further, the axle sleeve of described axial-flow leaf is aluminum axle sleeve.
Further, the wind path of described air-conditioner outdoor unit comprises inlet scoop, outdoor heat exchanger, outdoor motor, described axial-flow leaf and air outlet; The wind that described axial-flow leaf running is formed is entered by described inlet scoop, after described outdoor heat exchanger and described outdoor motor, is blown out by described air outlet.
The invention has the beneficial effects as follows:
The axial-flow leaf of dual blade structure, producing the different air-flow of intensity by the fan blade of the double labyrinth of size makes air form draught head, thus wind spreads blowout again after can be made to concentrate before fan blade, reach the object strengthening air output, air output can be made to increase 30%, make outdoor heat exchanger heat transfer effect better, not only realize the more energy-efficient of air-conditioning system, but also reduce off-premises station noise by reducing outdoor motor rotating speed.

In figure: 1 be inner ring fan blade, 2 be outer ring fan blade, 3 be axle sleeve, 4 be off-premises station, 5 be inlet scoop, 6 be outdoor heat exchanger, 7 be outdoor motor, 8 be axial-flow leaf, 9 for air outlet.
Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the axial-flow leaf of the dual blade structure of the present invention and the air-conditioner outdoor unit of applying this axial-flow leaf.
See accompanying drawing 1-2, air-conditioner outdoor unit 4 axial-flow leaf 8 comprises inner ring fan blade 1 and outer ring fan blade 2 double structure, and inner ring fan blade 1 diameter is less, and fan blade number is less; Outer ring fan blade 2 diameter is comparatively large, and fan blade number is more; The wind path of off-premises station 4 comprises inlet scoop 5, outdoor heat exchanger 6, outdoor motor 7, axial-flow leaf 8 and air outlet 9; Axial-flow leaf 8 is arranged on outdoor motor 7 by the axle sleeve 3 in fan blade, drives running by outdoor motor 7; The wind that axial-flow leaf 8 running is formed is entered by inlet scoop 5, after outdoor heat exchanger 6 and outdoor motor 7, blown out by air outlet 9, thus the heat produced that operated by air-conditioner is taken away.
The material of axial-flow leaf can be the compound of plastics and glass.The axle sleeve of axial-flow leaf can be aluminum.
Axial-flow leaf can be applied to the off-premises station of multiple air-conditioning.
The operation principle of the air-conditioner outdoor unit of application axial-flow leaf 8 is as follows: axial-flow leaf 8 comprises inner ring fan blade 1 and outer ring fan blade 2 double structure, and inner ring fan blade 1 diameter is less, and fan blade number is less, and outer ring fan blade 2 diameter is comparatively large, and fan blade number is more.Inner ring fan blade 1 is generally 1: 2 with the diameter ratio of outer ring fan blade 2, and the fan blade number of inner ring fan blade 1 is generally 2 or 3, and the fan blade number of outer ring fan blade 2 is generally 3 to 6.Wind inside when axial-flow leaf 8 operates is slightly weak, and the wind in outside is slightly strong, can produce the different air-flow of intensity by the fan blade of the double labyrinth of size like this makes air form draught head, strengthen the wind inside axial-flow leaf 8, thus spread blowout again after wind can be made to concentrate before axial-flow leaf 8, just can reach the object strengthening air output, air output can be made to increase 30%, make outdoor heat exchanger 6 heat transfer effect better, realize the more energy-efficient of air-conditioning system.Can reduce axial-flow leaf 8 winding number simultaneously, air output and existing axial-flow leaf air output are consistent, making to reduce outdoor motor 7 rotating speed like this becomes possibility, just can reduce off-premises station 4 noise.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
