Description

Technical Field

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

[0002] Axial flow fans are a common type of air-cooled heat dissipation fan in industrial applications. Due to their simple structure, light weight, low price, and good heat dissipation effect, they are widely used in automotive engine cooling, industrial ventilation and heat dissipation, and air conditioning cooling.

[0003] like Figure 1 As shown, the traditional installation method is to directly install the fan 300 into the radiator module 100, place the fan frame 200 on the fins of the radiator module 100, and then install a baffle 400 to fix the fan 300. In this installation method, the fan blades are close to the heat dissipation fins, which often puts the fan in a higher back pressure installation environment, causing the overall heat dissipation working point to move up, and the power consumption and noise will increase, which cannot meet the usage requirements. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to provide a radiator fan that is easy to install and reduces vibration and noise.

[0005] Based on the above problems, the technical solution provided by the present invention is:

[0006] A radiator fan is used to be installed on a radiator, wherein the radiator includes a radiator body and an installation cavity provided on the radiator body, comprising:

[0007] a bottom plate, which is detachably connected to the radiator body and covers the outside of the installation cavity;

[0008] A fan mechanism is installed on the bottom plate and accommodated in the installation cavity, with a distance between the fan mechanism and the bottom of the installation cavity.

[0009] In some embodiments, a fan mounting seat is provided in the middle of the base plate, and a plurality of guide holes are provided on the base plate at the periphery of the fan mounting seat.

[0010] In some embodiments, the fan mechanism includes a sleeve fixedly connected to the fan mounting base, a rotating shaft rotatably supported in the sleeve, a stator assembly installed outside the sleeve, and a fan blade assembly fixedly connected to the rotating shaft and located on the periphery of the stator assembly.

[0011] In some embodiments, the stator assembly includes a stator core fixed to the outer periphery of the sleeve and a stator winding disposed on the stator core.

[0012] In some embodiments, the fan blade assembly includes a magnetic sleeve fixedly connected to the rotating shaft, a fan sleeve fixed to the outer periphery of the magnetic sleeve, and a plurality of fan blades fixed to the outer periphery of the fan sleeve.

[0014] In some embodiments, the rotating shaft is supported in the sleeve via a bearing assembly.

[0015] In some embodiments, the fan mounting seat is provided with a mounting groove for the sleeve to be placed therein.

[0016] In some embodiments, a plurality of mounting screw holes are provided on the base plate.

[0017] In some embodiments, the bottom plate is provided with at least two positioning holes for the positioning posts to pass through.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) The radiator fan and the base plate are integrally mounted on the radiator body. There is a gap between the fan mechanism and the bottom of the mounting cavity, which increases the distance between the fan blades and the radiator fins, reducing noise while ensuring the heat dissipation effect;

[0020] (2) The fan mechanism is installed on the base plate, which reduces the number of connecting parts between the fan mechanism and the radiator body, reduces the thermal resistance during heat transfer, and enables heat to be transferred from the heat source to the heat dissipation module more quickly and efficiently, and then discharged through the fan, thereby improving the overall heat dissipation performance.

[0037] like Figure 2 As shown, it is a structural schematic diagram of an embodiment of the utility model, which provides a radiator fan for installation on a radiator. The radiator includes a radiator body 8 and an installation cavity 8-2 arranged on the radiator body 8-1. The radiator fan is installed in the installation cavity 8-2, and the outer periphery and bottom of the installation cavity 8-2 are the fins of the radiator.

[0038] Specifically, the radiator fan includes a base plate 1 and a fan mechanism installed on the base plate 1, and there is a distance between the fan mechanism and the bottom of the installation cavity 8-2.

[0039] like Figure 3 As shown, the base plate 1 is a rectangular plate structure, which is detachably connected to the radiator body 8-1 and covers the outside of the installation cavity 8-2. A fan mounting seat 1-1 is provided in the middle of the base plate 1, and a plurality of guide holes 1-2 are provided on the base plate 1 at the periphery of the fan mounting seat 1-1.

[0040] In order to facilitate the installation of the base plate 1 on the radiator body 8-1, a plurality of mounting screw holes 1-3 are provided on the base plate 1. Specifically, mounting screw holes 1-3 can be respectively provided on the four top corners of the base plate 1, and the base plate 1 is fixed to the radiator body 8-1 by a plurality of screws.

[0041] In order to facilitate the positioning of the base plate 1 during installation, at least two positioning holes 1-4 for the positioning columns to pass through are provided on the base plate 1. For example, two positioning holes can be set at the diagonal positions of the base plate 1, and corresponding positioning columns are set on the radiator body 8-1. The positioning of the base plate 1 is achieved through the cooperation between the positioning columns and the positioning holes 1-4.

[0042] The fan mechanism includes a sleeve 2 fixedly connected to the fan mounting base 1-1, a rotating shaft 4 rotatably supported within the sleeve 2, a stator assembly 3 mounted outside the sleeve 2, and a fan blade assembly 6 fixedly connected to the rotating shaft 4 and located on the periphery of the positioning assembly 3. The rotating shaft 4 is supported within the sleeve 2 via a bearing assembly. For example, the bearing assembly includes two bearings 5 ​​arranged one above the other. The rotating shaft 4 is tightly fitted with the inner rings of the bearings 5, and the outer rings of the bearings are tightly fitted with the sleeve 2, thereby stably supporting the rotating shaft 4 within the sleeve 2.

[0043] The stator assembly 3 includes a stator core 3 - 1 fixed to the outer periphery of the sleeve 2 and a stator winding 3 - 2 arranged on the stator core 3 - 1 .
