Description

A frame structure for a cooling fan Technical Field

[0001] This utility model relates to the field of air coolers, and more particularly to a frame structure for an air cooler. Background Technology

[0002] Traditional evaporator frame structures have several shortcomings. First, in terms of structural design, the front and rear frames of the evaporator may not be securely fixed. During prolonged high-speed rotation, the impeller is prone to loosening, affecting its rotational stability. This not only generates significant noise but may also cause the impeller to collide with other components, shortening the evaporator's lifespan. Furthermore, traditional impeller cover installation methods can be complex, hindering future maintenance and replacement.

[0003] Furthermore, in terms of dust prevention, the dust prevention measures at the air inlet of ordinary air coolers are relatively simple, possibly consisting of only a simple filter screen. The dust filtration effect is limited. After prolonged use, dust can easily enter the fan and accumulate on the fan assembly and other components, affecting the fan's heat dissipation performance and normal operation. It may also contaminate the water in the water tank, reducing the cooling efficiency of the air cooler. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a frame structure for a cooling fan, based on the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a frame structure of a cooling fan, including a fan body, the fan body including a fan frame, a fan device disposed in the fan frame, and a water tank disposed at the lower end of the fan frame. The fan frame has an air inlet and an air outlet respectively. The fan frame is circular. A connecting part for connecting with the water tank is extended at the lower end of the fan frame. An impeller assembly and a dust filter plate are disposed at the front and rear ends of the fan frame. An air inlet groove for arranging the dust filter plate is arranged along the air inlet of the fan frame. An air outlet groove for arranging the impeller is arranged along the air outlet of the fan frame.

[0006] The aforementioned components achieve the following effects: The circular fan frame, compared to traditional square or other shapes, offers superior aerodynamics, allowing for smoother airflow in and out, reducing turbulence at the frame's edges, and effectively improving airflow efficiency, thereby enhancing the overall cooling performance of the evaporator. The extended connection at the lower end of the fan frame ensures a tighter and more convenient connection between the frame and the water tank, preventing leaks due to loosening during movement and improving the user experience. The inlet and outlet grooves provide optimal space for the dust filter and impeller, optimizing the overall structural layout.

[0007] Preferably, the impeller assembly includes a fixed base, an impeller rotatably connected to the fixed base, a fixed sleeve bolted to the fixed base and passing through the impeller, and a protective cover covering the fixed sleeve.

[0008] The aforementioned components achieve the following effect: by assembling the impeller assembly, including a mounting base, impeller, mounting sleeve, and protective cover, the stability of the impeller during rotation is greatly improved. The mounting base provides stable support for the impeller, the bolted connection between the mounting sleeve and the mounting base further reinforces the impeller position, and the protective cover protects the impeller, effectively preventing noise and collision problems caused by impeller loosening, and extending the service life of the evaporator.

[0009] Preferably, the fixing sleeve has a plurality of fixing slots, and the protective cover extends to have an inner ring end that passes through the fixing sleeve. The inner ring end has a plurality of locking teeth corresponding to the fixing slots. The protective cover is mounted on the fixing sleeve by rotating and locking the fixing slots with the locking teeth.

[0010] The aforementioned components achieve the following effect: by creating several fixing slots within the fixed sleeve and setting corresponding locking teeth on the inner ring end of the protective cover, the protective cover is rotatably engaged with the fixing slots via the locking teeth, making installation and removal of the protective cover more convenient. Compared to traditional, complex installation methods, this facilitates later maintenance and replacement of the impeller assembly, reduces maintenance costs, and improves the maintainability of the evaporator fan.

[0011] Preferably, the fan frame is further provided with a reinforcing rib along the air inlet. The reinforcing rib is X-shaped and has a fixed end at its center. The fixed seat is bolted to the fixed end.

[0012] The aforementioned components achieve the following effects: by incorporating X-shaped reinforcing ribs along the air inlet within the fan frame, and arranging a fixed end at the center of the reinforcing ribs, the mounting base is bolted to the fixed end, thereby enhancing the overall structural strength of the frame. The X-shaped reinforcing ribs better distribute stress, providing more stable support for the mounting base, further ensuring the stability of components such as the impeller assembly, making the evaporator fan more reliable during operation, and reducing vibration and noise caused by structural instability.

[0013] Preferably, the air inlet groove is provided with a plurality of openings, and filter cotton is provided between the dust filter plate and the air inlet groove.

[0014] The aforementioned components achieve the following effect: by setting several openings in the air inlet groove and placing filter cotton between the dust filter plate and the air inlet groove, this multi-layer dustproof structure design significantly improves the dustproof effect compared to the traditional single-filter dustproof method. The openings facilitate airflow, and the filter cotton further adsorbs fine dust, reducing the possibility of dust entering the fan's interior. This ensures normal heat dissipation and operation of the fan unit, extends the cleaning cycle and lifespan of the air cooler, and reduces the impact of dust accumulation on the air cooler's performance.

[0015] Preferably, the dust filter plate is square or round, and the dust filter plate is installed in the air inlet groove by bolt connection.

[0016] The aforementioned components achieve the following effects: by setting the dust filter plate to be square or round and using bolt connections within the air inlet groove, a variety of shape options are available to adapt to different design requirements, increasing design flexibility. The bolt connection method ensures secure installation of the dust filter plate and facilitates easy disassembly, allowing for convenient cleaning or replacement of the dust filter plate and filter cotton when needed, further improving the practicality and maintainability of the air cooler's dustproof structure.

[0017] Compared with existing technologies, the advantages of this utility model are as follows: By setting up a fan body, fan frame, fan assembly, and water tank, the fan frame effectively improves air circulation efficiency and enhances cooling effect. Furthermore, the lower connection of the fan frame ensures a tight and convenient connection with the water tank, preventing leakage and improving user experience. The impeller assembly adopts a structure of fixed base, rotating impeller, fixed sleeve, and protective cover, greatly improving impeller rotation stability, reducing noise and impact, and extending service life. The protective cover is engaged with the fixed slot via locking teeth, facilitating installation and disassembly, and aiding in later maintenance and replacement. The air inlet groove has openings, and filter cotton is added between it and the dust filter plate, significantly improving dust prevention, reducing dust entry, ensuring normal fan operation, and extending cleaning cycles and service life. X-shaped reinforcing ribs enhance the structural strength of the frame, providing stable support for the impeller assembly. The choice of square or round dust filter plates and the bolt connection method increases design flexibility and maintainability. Attached Figure Description

[0027] In this embodiment 1,

[0028] As shown in Figures 1 to 3, this utility model provides a frame structure for a cooling fan, including a fan body. The fan body includes a fan frame 1, a fan device 2 disposed within the fan frame 1, and a water tank 3 disposed at the lower end of the fan frame 1. The fan frame 1 has an air inlet 4 and an air outlet 5. The fan frame 1 is circular. A connecting part 6 for connecting to the water tank 3 extends from the lower end of the fan frame 1. An impeller assembly 7 and a dust filter plate 8 are disposed at the front and rear ends of the fan frame 1. An air inlet groove 9 for arranging the dust filter plate 8 is arranged along the air inlet 4 on the upper side of the fan frame 1. An air outlet groove 10 for arranging the impeller 12 is arranged along the air outlet 5 on the upper side of the fan frame 1.

[0029] By designing the fan frame 1 in a circular shape, it offers aerodynamic advantages compared to traditional square or other shapes. This allows for smoother airflow in and out, reduces turbulence at the frame's edges, and effectively improves air circulation efficiency, thereby enhancing the overall cooling performance of the evaporator. The connecting part 6 extending from the lower end of the fan frame 1 ensures a tighter and more convenient connection between the frame and the water tank 3, preventing leaks caused by loose connections during movement and improving the user experience. The air inlet groove 9 and air outlet groove 10 provide reasonable space for the dust filter plate 8 and impeller 12, respectively, optimizing the overall structural layout.

[0030] The impeller assembly 7 includes a fixed base 11, an impeller 12 rotatably connected to the fixed base 11, a fixed sleeve 13 bolted to the fixed base 11 and passing through the impeller 12, and a protective cover 14 covering the fixed sleeve 13.

[0031] By configuring the impeller assembly 7, which includes a mounting base 11, an impeller 12, a mounting sleeve 13, and a protective cover 14, the stability of the impeller 12 during rotation is greatly improved. The mounting base 11 provides stable support for the impeller 12, the bolted connection between the mounting sleeve 13 and the mounting base 11 further reinforces the position of the impeller 12, and the protective cover 14 protects the impeller 12, effectively preventing noise and collision problems caused by the impeller 12 becoming loose, and extending the service life of the evaporator.

[0032] The fixed sleeve 13 has a plurality of fixed slots 15, and the protective cover 14 extends to have an inner ring end 16 that passes through the fixed sleeve 13. The inner ring end 16 has a plurality of teeth 17 corresponding to the fixed slots 15. The protective cover 14 is rotated and locked onto the fixed sleeve 13 by the teeth 17 and the fixed slots 15.

[0033] By creating several fixing slots 15 within the fixing sleeve 13 and setting corresponding locking teeth 17 on the inner ring end 16 of the protective cover 14, the protective cover 14 is rotatably engaged with the fixing slots 15 via the locking teeth 17, making the installation and removal of the protective cover 14 more convenient. Compared to traditional, complex installation methods, this facilitates later maintenance and replacement of the impeller assembly 7, reduces maintenance costs, and improves the maintainability of the evaporator fan.

[0034] The fan frame 1 is also provided with a reinforcing rib 18 along the air inlet 4. The reinforcing rib 18 is arranged in an X shape, and a fixed end 19 is arranged at the center of the reinforcing rib 18. The fixed seat 11 is installed on the fixed end 19 by bolt connection.

[0035] By setting X-shaped reinforcing ribs 18 along the air inlet 4 inside the fan frame 1, and arranging a fixed end 19 at the center of the reinforcing ribs 18, the fixing seat 11 is bolted to the fixed end 19, thus enhancing the overall structural strength of the frame. The X-shaped reinforcing ribs 18 can better distribute stress, provide more stable support for the fixing seat 11, further ensure the stability of the impeller assembly 7 and other components, making the evaporator fan more reliable during operation and reducing vibration and noise caused by structural instability.

[0036] The air inlet groove 9 is provided with several openings, and a filter cotton 20 is provided between the dust filter plate 8 and the air inlet groove 9.

[0037] By setting several openings in the air inlet groove 9 and placing filter cotton 20 between the dust filter plate 8 and the air inlet groove 9, this multi-layer dustproof structure design greatly improves the dustproof effect compared to the traditional single-filter dustproof method. The openings facilitate air circulation, and the filter cotton 20 can further adsorb fine dust, reducing the possibility of dust entering the fan, ensuring the normal heat dissipation and operation of the fan device 2, extending the cleaning cycle and service life of the air cooler, and reducing the impact of dust accumulation on the performance of the air cooler.

[0038] The dust filter plate 8 is square or round, and is installed in the air inlet groove 9 by bolt connection.

[0039] By setting the dust filter plate 8 to be square or round and bolting it into the air inlet groove 9, a variety of shape options are provided to adapt to different design requirements, increasing design flexibility. The bolted connection method makes the dust filter plate 8 securely installed and easy to disassemble, facilitating the cleaning or replacement of the dust filter plate 8 and filter cotton 20 when needed, further improving the practicality and maintainability of the air cooler dustproof structure.

[0040] In this embodiment 2,

[0041] As shown in Figures 1 to 3, by setting up the fan body, fan frame 1, fan assembly 2, and water tank 3, the fan frame 1 effectively improves air circulation efficiency and enhances cooling effect. The lower end connection 6 of the frame ensures a tight and convenient connection with the water tank 3, preventing leakage and improving user experience. The impeller assembly 7 adopts a structure of fixed base 11, rotating impeller 12, fixed sleeve 13, and protective cover 14, greatly improving the rotational stability of the impeller 12, reducing noise and impact, and extending service life. The protective cover 14 is rotatably engaged with the fixed slot 15 via clips 17, facilitating installation and disassembly, and aiding in later maintenance and replacement. The air inlet groove 9 has openings, and filter cotton 20 is added between it and the dust filter plate 8, significantly improving dust prevention, reducing dust entry, ensuring normal fan operation, and extending cleaning cycles and service life. X-shaped reinforcing ribs 18 enhance the structural strength of the frame, providing stable support for the impeller assembly 7. The choice of square or round shape for the dust filter plate 8 and the bolt connection method increase design flexibility and maintainability.

[0042] In this embodiment 3,

[0043] As shown in Figures 1 to 3, when the evaporator is running, air enters through the air inlet 4 of the fan frame 1. The dust filter plate 8 at the air inlet 4 first filters and intercepts larger dust particles in the air, while the filter cotton 20 located between the dust filter plate 8 and the air inlet groove 9 further adsorbs fine dust. After these two layers of filtration, the possibility of dust entering the fan is effectively reduced. At the same time, air enters the fan frame 1 through the opening on the air inlet groove 9. The X-shaped reinforcing ribs 18 arranged along the air inlet 4 inside the frame not only enhance the overall structural strength of the frame, but the fixed end 19 arranged in the center is also firmly connected to the fixing seat 11 of the impeller assembly 7 by bolts, ensuring the stability of the impeller assembly 7 installation. In the impeller assembly 7, the impeller 12 is rotatably connected to the fixing seat 11, and the fixing sleeve 13 passing through the impeller 12 is bolted to the fixing seat 11, further reinforcing the position of the impeller 12.
