[0001] The present application relates to the technical field of automobile air conditioners, and in particular to an impeller for an automobile air conditioner and an automobile air conditioner. Background Art
[0002] Currently, automotive air conditioning blowers on the market generally use traditional multi-blade centrifugal impellers. However, due to space constraints and the limitations of the blower itself, it is difficult to further increase the air volume without changing the existing size.
[0003] New energy vehicles currently require 20% to 40% higher air volume than traditional air conditioning units. To meet this demand, existing blower speeds exceed 4,000 rpm, resulting in noise levels that fall short of customer expectations. Furthermore, high blower speeds increase the requirements for dynamic balance and material strength, increasing manufacturing complexity and costs. Utility Model Content
[0004] In view of this, the purpose of the present application is to provide an impeller for a car air conditioner and a car air conditioner, so as to solve the problem that the air volume of the existing car air conditioner is difficult to further increase.
[0005] According to a first aspect of the present invention, an impeller for an automobile air conditioner is provided, wherein the impeller for an automobile air conditioner comprises: an impeller body; a first blade, wherein a plurality of the first blades are arranged at intervals along the circumferential direction of the impeller body; and a second blade, which is arranged between two adjacent first blades, wherein the height of the second blade is less than the height of the first blade.
[0006] Preferably, there are a plurality of the second blades, and at least one second blade is provided between every two adjacent first blades.
[0007] Preferably, the number of the second blades is equal to the number of the first blades, and the second blades and the first blades are arranged alternately.
[0008] Preferably, the number of the first blades is 41 to 47.
[0009] Preferably, the impeller for the automobile air conditioner further comprises an impeller guard ring, which is arranged on the upper part of the impeller body, and the tops of the plurality of first blades are connected through the impeller guard ring.
[0010] Preferably, the first blade and the second blade are formed in an arc shape, and the bending direction of the first blade and the second blade is the same.
[0011] Preferably, one end of the second blade close to the middle of the impeller body is formed as a first curved portion, and one end of the second blade away from the middle of the impeller body is formed as a second curved portion, and the thickness of the first curved portion is greater than that of the second curved portion.

[0031] like Figures 1 to 3 As shown, according to a first aspect of the present invention, an impeller for an automobile air conditioner is provided. The impeller for an automobile air conditioner includes an impeller body 3 , a first blade 1 and a second blade 2 .
[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the above components of the impeller for automobile air conditioner and the connection relationship of the above components are described in detail.
[0033] like Figures 1 to 3As shown, in this embodiment, multiple first blades 1 can be spaced apart along the circumference of the impeller body 3. The second blades 2 can be positioned between two adjacent first blades 1. The height of the second blades 2 is less than that of the first blades 1. In a multi-blade centrifugal impeller, the effective working area of the blades is the lower two-thirds. This arrangement significantly improves the working capacity of the lower portion of the impeller for automotive air conditioning without changing the original dimensions, and reduces manufacturing costs.
[0034] Preferably, Figures 1 to 3 As shown, in the embodiment, the first blade 1 can be formed as a strip plate, and the length (ie, height) direction of the first blade 1 can be as follows: Figure 1 The first blade 1 is arranged along the axial direction of the impeller for the automobile air conditioner. The plate surface of the first blade 1 can be formed into an arc shape, the curvature of each first blade 1 can be equal, and the first blades 1 can be arranged at equal intervals.
[0035] Preferably, Figures 1 to 3 As shown, in the embodiment, the second blade 2 can be formed as a strip-shaped plate with a smaller length, and the length (ie, height) direction of the second blade 2 can also be as follows: Figure 1 The second blades 2 are arranged in the vertical direction as shown, that is, along the axial direction of the impeller for the automobile air conditioner. The plate surface of the second blades 2 can also be formed into an arc shape, so that the second blades 2 can be inserted between the first blades 1.
[0036] Preferably, Figures 1 to 3 As shown, in the embodiment, the number of second blades 2 can be multiple, so that a second blade 2 can be provided between multiple first blades 1, thereby increasing the air volume. Furthermore, preferably, at least one second blade 2 can be provided between each two adjacent first blades 1 (that is, multiple second blades can also be provided between two adjacent second blades), so that the air volume can be further increased.
[0037] More preferably, Figures 1 to 3 As shown, in this embodiment, the number of first blades 1 and second blades 2 can be equal. In this case, only one second blade 2 is provided between each two adjacent first blades 1, i.e., the second blades 2 are arranged alternately with the first blades 1. This arrangement ensures that the impeller for the automotive air conditioner can increase the air volume while ensuring a relatively uniform air distribution.
[0038] Preferably, Figures 1 to 3As shown, in the embodiment, the number of the first blades 1 can be 41 to 47, and the number of the second blades 2 is the same as the number of the first blades 1. This arrangement can reduce the required manufacturing cost while ensuring that the impeller for the automotive air conditioner has sufficient air volume.
[0039] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the impeller for an automotive air conditioner may further include an impeller guard ring 4. The impeller guard ring 4 may be disposed above the impeller body 3 (i.e., disposed axially). The bottoms of the plurality of first blades 1 may be connected to the impeller body 3, while the tops of the plurality of first blades 1 may be connected via the impeller guard ring 4 to ensure the overall strength of the impeller for an automotive air conditioner. Preferably, the first blades 1 may be integrally formed with the impeller guard ring 4 and the impeller body 3.
[0040] More preferably, Figure 1 and Figure 3 As shown, in this embodiment, the bottom of the second blade 2 can be connected to the impeller body 3. Because the height of the second blade 2 is less than that of the first blade 1, no connecting structure is provided between the second blades 2. In this case, the height of the second blade 2 can be 10 mm to 15 mm, ensuring the structural strength of the second blade 2 while still being able to perform its function.
[0041] Preferably, Figure 3 As shown, in this embodiment, one end of the second blade 2 near the middle of the impeller body 3 can be formed into a first curved portion 21. The end of the second blade 2 away from the middle of the impeller body 3 can be formed into a second curved portion 22. Preferably, the thickness of the first curved portion 21 can be greater than the thickness of the second curved portion 22. This arrangement can further increase the airflow of the impeller for the automotive air conditioner.
[0042] In addition, preferably, Figures 1 to 3 As shown, in an embodiment, the first blade 1 and the second blade 2 can be arranged on the periphery of the impeller body 3. Specifically, the impeller body 3 can be formed into a disc shape, and the thickness of the periphery of the impeller body 3 is relatively thin. The first blade 1 and the second blade 2 can extend from the periphery of the impeller body 3 in the width direction (i.e., the extension direction of the arc surface of the first blade 1 and the second blade 2), and the first blade 1 and the second blade 2 can be passed through the periphery of the impeller body 3 in the vertical direction to achieve the function of airflow guidance. Preferably, the bending directions of the first blade 1 and the second blade 2 can be the same, that is, the concave surface of the first blade 1 and the convex surface of the second blade 2 are arranged opposite to each other.
[0043] In addition, according to a second aspect of the present invention, an automobile air conditioner is provided, which includes the impeller for automobile air conditioner as described above. The impeller for automobile air conditioner can be the impeller for automobile air conditioner in the above embodiment.
[0044] During use, multiple first blades 1 and multiple second blades 2 are alternately arranged along the circumferential direction of the impeller body 3, so that the working capacity of the impeller for the automobile air conditioner is significantly improved without changing the original size, and the noise generated is small and the manufacturing cost is low.
[0045] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto.
