Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] To better describe and illustrate the embodiments of the present application, one or more accompanying drawings may be referred to, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of any of the utility models, embodiments currently described, or preferred modes of the present application.

It is only for the convenience of describing the present utility model and does not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] The axial-flow centrifugal fan bracket is a part of the fan, used to connect the fan and the panel and fix the fan on the panel. In the existing axial-flow centrifugal fan brackets, they often have a complex structure, a large volume, and are inconvenient to install. This not only occupies valuable space inside the freezer but also results in a high manufacturing cost. Therefore, developing a more compact, lightweight, and cost-effective fan bracket has become an important direction in the industry.

[0030] In view of this, the present utility model proposes an axial-flow centrifugal fan bracket. Figures 1-4 For an embodiment of the axial-flow centrifugal fan bracket provided by the present utility model, please refer to Figures 1-4 , the axial-flow centrifugal fan bracket 100 includes a first bracket 1 for connecting the motor and a second bracket 2 for connecting the panel.

[0031] Specifically, the first bracket 1 extends along the radial direction of the fan, its length is greater than the maximum diameter of the fan, and its two ends extend beyond the outer peripheral edge of the fan; the two second brackets 2 are respectively connected to the two ends of the first bracket 1 and extend along the axial direction of the fan. Among them, a positioning pin 211 is provided at the end of the second bracket 2 for positioning and cooperating with the shaped hole of the panel.

[0032] In the technical solution of the present utility model, the first bracket 1 and the second bracket 2 are respectively connected to the fan and the panel. The first bracket 1 extending radially along the fan and the second bracket 2 extending axially along the fan are connected to each other to form an L-shaped structure, and are positioned by the positioning pin 211 at the end of the second bracket 2 to fix the axial flow fan. This bracket structure is simple, can be quickly disassembled, and its volume is greatly reduced compared with the frame-type bracket, occupying less installation space.

[0033] To connect the fan to the bracket, please refer to Figures 1-4 , in an embodiment of the present utility model, a through hole 11 is provided in the middle of the first bracket 1, and its inner contour is adapted to the outer contour of the motor controller 3 of the fan, so that the first bracket 1 is sleeved on the outer periphery of the motor controller 3 of the fan.

[0034] Furthermore, please refer to Figure 1 、 2 and 4, in an embodiment of the present utility model, the first bracket 1 is provided with a first mounting hole 12 and a first bolt along the outer periphery of the through hole 11 for threaded connection with the shaped hole of the motor. The connection part between the first bracket 1 and the motor is simple, and it is connected to the motor base through bolts, without any restrictions on the motor controller 3. Therefore, when a problem occurs in the motor controller 3 part, only the motor controller 3 needs to be disassembled and replaced.

[0035] To improve the strength of the bracket, in an embodiment of the present utility model, the whole bracket is made of nylon plus glass fiber PA66+GF30, that is, the first bracket 1 and the second bracket 2 are integrally injection molded. PA66 reinforced with 30% glass fiber generally has characteristics such as high hardness, wear resistance, high temperature resistance, tensile resistance, and aging resistance, and can be used for the covers of mechanical parts that require high rigidity and dimensional stability.

[0036] To improve the support strength of the bracket, please refer to Figures 1-4 , in an embodiment of the present utility model, both the first bracket 1 and the second bracket 2 are plate-shaped, and their compressive strength is greatly improved compared with the rod-shaped ones.

[0037] In an embodiment of the present utility model, the thickness of the plate-shaped first bracket 1 and the second bracket 2 is 3mm. Compared with the traditional metal bracket, this thickness of the bracket reduces the weight of the bracket after injection molding, reduces the surface spraying cost, is convenient for opening internal threads, and is convenient for disassembly and assembly.

[0038] In an embodiment of the present utility model, please refer to Figure 1 、 2With respect to 4, a plurality of waist-shaped holes 13 for ventilation are provided at the air outlet position of the plate-shaped second bracket 2, and the waist-shaped holes 13 are subjected to arc transition treatment, which can reduce air flow interference and noise. It should be noted that the waist-shaped holes 13 are of the same size and are arranged in a matrix, which has a small impact on the strength of the bracket and can reduce the influence of the bracket on the air outlet during the operation of the fan.

[0039] For the convenience of connecting the bracket to the panel, please refer to Figures 1-4 In an embodiment of the present invention, the end of the second bracket 2 is a mounting plate 21 extending along the radial direction of the fan, and a positioning pin 211 is provided on the mounting plate 21.

[0040] Furthermore, please refer to Figure 3 The positioning pin 211 extends along the axial direction, and the mounting plate 21 is provided with a second mounting hole 212 and a second bolt along the outer periphery of the positioning pin 211. By providing the positioning pin 211, the second mounting hole 212 can be aligned with the shaped hole of the panel, which is convenient for the bolt to perform threaded connection and facilitates the workers to perform loading, unloading and subsequent maintenance work. It should be noted that when the air outlet is on the side, the mounting plate 21 is fixed to the wall panel; when the air outlet is on the top, the mounting plate 21 is fixed to the top plate of the cabinet.

[0041] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0042] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
