Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an axial magnetic fan. Background Art

[0002] Traditional motors are radial flux motors. As Figure 1 shown, the power of the motor is proportional to the axial length. The axial length of the motor is restricted by the space of the winding end and the installation structure, and it is very difficult to make it relatively short. Generally, it has a slender structure. The diameter of the rotor 20 is small and the moment of inertia is small, which can achieve a relatively high rotational speed. However, the torque of the motor is small, it is very difficult to output a large torque and the power density is low. If a large torque needs to be output, the volume of the motor will be very large. In some scenarios, the fan needs to be very thin to meet the installation requirements. At this time, if a traditional radial flux motor is used in the fan, it will inevitably cause the fan to be unable to be installed.

[0003] There are also some fans using axial flux motors in the existing published patents. For example, the application number is 201610303997.7, which includes a moving impeller hood, a moving impeller, a fixed impeller, an axial flux brushless motor, a motor hood, and a motor drive board arranged in the motor hood. The axial flux brushless motor includes a motor stator, a first motor rotor, a second motor rotor, and a motor shaft. The second motor rotor is arranged between the moving impeller and the motor stator and is fixedly connected to the moving impeller. The first motor rotor is arranged between the motor drive board and the motor stator, and the motor stator is arranged between the first motor rotor and the second motor rotor. Although this scheme adopts the axial flux scheme, the structural layout of this scheme is unreasonable and still cannot reduce the size of the fan.

[0004] In summary, the technical problem to be solved by this application is: how to optimize the structure of the fan to meet the purpose of reducing the size of the fan. Content of the Utility Model

[0039] The technical solutions of the present application will be further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0040] As Figures 2 to 9 shown, this embodiment provides an axial magnetic ventilator, including:

[0041] An air hood 11, one end of the air hood 11 along its own axis is provided with an air inlet 12, and an air outlet 13 is provided on the circumferential surface of the air hood 11;

[0042] The stator base 14 is disposed at one end of the wind cover 11 away from the air inlet 12, and a bearing chamber 15 is provided on the stator base 14;

[0043] The bearing assembly 16 is installed in the bearing chamber 15;

[0044] The fan 17 is disposed in the wind cover 11, and the fan 17 is installed in the bearing assembly 16 through the mounting shaft 18;

[0045] The stator assembly is installed on the stator base 14;

[0046] The rotor assembly is installed on the fan 17.

[0047] The technical effect of this solution is that the blower of this solution adopts the form of an axial flux motor and is installed at the open end of the wind cover 11 through the stator base 14, so that the size of the blower can be made very thin, effectively reducing the size of the blower.

[0048] The stator base 14 in this solution has a mounting plate, the mounting plate is directly fixed on the wind cover 11, and the bearing chamber 15 is disposed at the center of the mounting plate.

[0049] When the stator assembly is energized, the rotor assembly drives the fan 17 to rotate under the action of electromagnetic force, the air flow flows into the wind cover 11 through the air inlet 12, and is discharged at high speed through the air outlet 13.

[0050] This solution also has other advantages. For example, by designing an axial flux motor and increasing the diameter of the rotor, the radial dimension of the mounting shaft 18 can be reduced, making full use of the radial dimension space.

[0051] Furthermore, the fan 11 has centrifugal, axial flow, and mixed flow impellers; and it can be a single impeller or a double impeller, or a combination of both.

[0052] Figure 2 and Figure 6 The blower in Figure 2 and Figure 6 has a different structure from the wind cover 11 in

[0053] Figure 4 and Figure 8 The blower in Figure 4 and Figure 8 has a different structure from the wind cover 11 in

[0054] Furthermore, as Figure 10 shown, the stator assembly includes a plurality of stators 19.

[0055] Furthermore, as Figure 3 shown, the rotor assembly includes:

[0056] The rotor housing 21 is mounted on the base portion 22 of the fan 17;

[0057] The rotor 20 is disposed on the rotor housing 21.

[0058] As Figure 10 and Figure 11 shown, the stator 19 and / or the rotor 20 is / are fan-shaped. Among them, the stator 19 includes a coil 25, and the current direction of the coil 25 is arranged in a fan-shaped surrounding manner.

[0059] Furthermore, as Figure 11 shown, the number of rotors 20 is multiple, and the rotor 20 includes magnets.

[0060] As an implementation manner of this embodiment, as Figure 3 shown, the fan 17 includes:

[0061] The base portion 22, and a rotor assembly is mounted on one side of the base portion 22 facing the bearing assembly 16;

[0062] The blades 23 are disposed on the base portion 22.

[0063] The wind hood 11 in this solution can be set to one or two. The technical terms "thick" and "thin" involved in this article refer to the length along the axial direction of the fan.

[0064] When the number of wind hoods 11 is one, as Figure 3 and Figure 7 shown, this installation method can make the entire fan very thin.

[0065] When the number of wind hoods 11 is two, the two wind hoods 11 are respectively disposed on both sides of the stator base 14, and fans 17 are respectively provided in the two wind hoods 11. At this time, the thickness of the fan will increase, but this method is still much thinner than the traditional radial magnetic fan, and the air outlet efficiency of the fan can be increased. In this arrangement, there are also two forms of setting the rotor assembly.

[0066] The first method is that only one of the two fans 17 is mounted with a rotor assembly. The second method, as Figure 5 and Figure 9 shown, the number of rotor assemblies is two, and each fan 17 is mounted with a rotor assembly. The second method can significantly improve the energy efficiency of the fan 17 during operation.

[0067] As an implementation manner of this embodiment, as Figure 3 shown, the bearing assembly 16 includes two bearings 24, and the two bearings 24 are respectively disposed at both ends of the bearing chamber 15. This method can effectively ensure the stable and efficient operation of the mounting shaft 18.

[0068] For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
