Embodiment
Below by drawings and examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the structure diagram of the embodiment for the utility model air-conditioning internal machine.In the present embodiment, it is empty
Machine includes in tune：Internal air passage 11 and counter-rotating fan 2.Internal air passage 11 and the air inlet 12 and exhaust outlet 13 of air-conditioning internal machine connect
Logical, counter-rotating fan 2 is arranged in internal air passage 11, for guiding air-flow to flow to exhaust outlet from air inlet 12 along internal air passage 11
13。
Internal air passage 11 can be formed in inside the body 1 of air-conditioning internal machine, and air inlet 12 and exhaust outlet 13 may be referred to
The both ends in internal air passage 11 are separately positioned on shown in Fig. 1.In another embodiment, the setting position of air inlet 12 and exhaust outlet 13
The other positions that end is removed in internal air passage 11 can also be arranged on by putting.Internal air passage 11 may be referred to shown in Fig. 1 vertically
Set, and air inlet 12 is arranged on to the lower position of body 1, exhaust outlet 13 is arranged on to the upper position of body 1.At other
In embodiment, the inside air passage of horizontal direction or incline direction can also be used, air inlet and gas outlet can also be relative to machines
Body 1 is arranged in other positions.
Counter-rotating fan 2 is optional including the first axial flow blower 21 and the second axial flow blower 22, the first axial flow blower 21 and second
22 axially adjacent arrangement of axial flow blower, and the first axial flow blower 21 and the second axial flow blower 22 is oppositely oriented.That is,
If the first axial flow blower 21 rotates clockwise, the second axial flow blower 22 rotates counterclockwise；It can also be the first axial flow blower
21 rotations counterclockwise, then the second axial flow blower 22 rotates clockwise.Can be arranged in internal air passage 11 more than one group to rotation
Wind turbine 2, oppositely oriented two axial flow blowers, which can provide, solves the problems, such as that single axial flow blower static pressure is less, and compared to
It is limited less centrifugal blower on installation direction and position, freer in design.
With reference to figure 1 and Fig. 2, the first axial flow blower 21 can include axial-flow leaf 211 and motor 212, the second axis galvanic electricity machine
22 can include axial-flow leaf 221 and motor 222.Motor 212 and 222 is separate, and spatially adjacent, 212 He of motor
222 motor output shaft can be stretched out to the opposite direction of same axis.Axial-flow leaf 211 and 221 may be mounted at motor output
On axis, it can also be installed on motor housing.
In one embodiment, with reference to figure 3, the axial-flow leaf 2a in the first axial flow blower 21 and the second axial flow blower 22 is equal
Using external rotor electric machine provide driving force, that is to say, that motor 212 and 222 is external rotor electric machine, the shell of this motor with
The inner ring 2b fixed settings of axial-flow leaf 2a, the output shaft of external rotor electric machine are fixed relative to internal air passage 11.Another
Any one in a embodiment or in the first axial flow blower 21 and the second axial flow blower 22 uses external rotor electric machine, separately
One uses inner rotor motor.
In order to facilitate the fixation of the output shaft of external rotor electric machine, can be set in internal air passage 11 and 11 phase of internal air passage
To fixed stent, output shaft and the stent of external rotor electric machine are fixed.Such as cross branch is set in internal air passage 11
Frame, the center of stent and the output shaft of external rotor electric machine are fixed.This external rotor electric machine is since output shaft is fixed, axial-flow leaf 2a
Inner ring 2b and the shell of external rotor electric machine fix, therefore the jib-length of corresponding axial flow blower is 1/2 outer cover length+output
Shaft length, it is shorter than the jib-length (being equal to outer cover length+output shaft length) of inner rotor motor, therefore bending load is more
It is low.
With reference to figure 2, the quantity of the axial blade of the axial blade of the first axial flow blower 21 and the second axial flow blower 22 is preferred
Prime number each other, the covibration that may occur when being run with eliminating.For example, axial-flow leaf 211 includes 6 fan blades, axial-flow leaf
221 include 7 fan blades.In addition, the first axial flow blower 21 and the second axial flow blower 22 can be exchanged relative to air motion direction
Position, can adjust blade angle and rotation direction accordingly as the case may be.
If by the above-mentioned air-conditioning internal machine embodiment using counter-rotating fan 2 of the utility model with using single axial flow blower
Air-conditioning internal machine is in same design air quantity (such as 1200m3/ h) and rotating speed (N=960rad/min) under be compared, this practicality is new
Type air-conditioning internal machine embodiment will be reduced by about on the outer diameter of counter-rotating fan compared to the outer diameter of single axial flow blower
20%, increase by 18% on static pressure, increase by 10% in efficiency.
In order to further reduce the installation space of air-conditioning internal machine, with reference to figure 1, the air-conditioning internal machine embodiment of the utility model is also
It may further include the heat exchanger 3 for being arranged on V-shaped layout in internal air passage 11.The heat exchanger of this V-type layout compared to
The heat exchanger of existing yi word pattern layout adds heat exchange area by about one time, and simultaneously unobvious on the arrangement space in body 1
Increase.
In Fig. 1, heat exchanger 3 is optional is arranged in internal air passage 11 relative to 12 inner side of air inlet, so as into
Gas position is just more fully exchanged heat, and the temperature difference between exhaust outlet air-flow and the external world can be reduced compared to other positions,
To reduce or eliminate the dew condensation phenomenon of exhaust outlet.Specifically, heat exchanger 3 is preferably located to the lower section of counter-rotating fan 2.In addition,
Drip tray 4 can also be set below heat exchanger 3, so as to which the water droplet of confluence can be accepted in condensation on heat exchanger 3, avoid dirt
Dye or corrosion body 1.
Above-mentioned each air-conditioning internal machine is applicable to all kinds of apparatuses of air conditioning, is particularly suitable for application to air conditioner.Therefore, this reality
A kind of air conditioner, including foregoing air-conditioning internal machine are additionally provided with new, can reach and reduce the technology effect that installation space takes
Fruit.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it should all cover in the claimed technical solution of the utility model
Among scope.
