Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to an air-cooled impeller with a new structure. Background Art

[0002] The air-cooled impeller is a rotating device, usually composed of multiple blades. Its working principle is to transmit wind or airflow to the blades to make them rotate. When the wind or airflow passes through the air-cooled impeller, the airflow will exert force on the blades. The shape and angle of the blades can make the wind force produce a torque in a certain direction. When the torque exerted by the airflow on the blades is greater than the resistance torque of the blades, the blades will rotate.

[0003] At present, the known air-cooled impeller structure is composed of an end cover and blades. When the fan is running, electrical loss and mechanical loss will generate heat, which will cause the temperature of various parts of the fan to rise. Excessive temperature rise may cause the motor to burn out and the gas flow rate to fail to meet the requirements. Therefore, the heat dissipation of the air-cooled impeller plays a vital role in the stable and efficient operation of the fan.

[0004] However, the current air-cooled impeller structure is not reasonable enough. During the rotation of the impeller, higher power is required to produce the ideal air volume, which greatly reduces the efficiency, and the stability of the impeller is also insufficient. Therefore, a new type of air-cooled impeller with a new structure is proposed. Summary of the invention

[0005] In view of the deficiencies of the prior art, the utility model provides an air-cooled impeller with a new structure, which overcomes the deficiencies of the prior art and solves the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of air-cooled impeller, comprising a rear disc, a surface of which is fixedly connected with a plurality of blades 1, and the plurality of blades 1 are arranged circumferentially at equal intervals around the axis of the rear disc, a front disc is fixedly installed at one end of the plurality of blades 1 away from the rear disc, a guide sleeve is formed at the center of the rear disc, and a shaft connection sleeve is provided at the axis of the rear disc;

[0007] The shaft sleeve is provided with a wheel disc, and a plurality of blades 2 are fixedly installed on the wheel disc;

[0008] The end of the shaft connection sleeve away from the front disc is fixedly connected with a dynamic balance adjustment component.

[0009] It can be connected to the motor rotor structure through the shaft sleeve. As the motor rotor rotates, the rear disc can rotate synchronously. When the rear disc rotates, it can drive the surrounding air through blade one, and make the air flow inward along the air duct constructed by blade one. The symmetrical design of blade one can reduce the fluid resistance and energy loss. At the same time, blade two can further drive the air flow at the end of the rear disc, thereby increasing the air flow and improving the heat dissipation efficiency. The dynamic balancing adjustment component can be adjusted according to the operating conditions of the rear disc when it rotates synchronously on the rotor.

[0010] As a preferred technical solution of the utility model, the rear disc and the blade one are concentrically arranged, and an assembly positioning hole is opened on the rear disc.

[0011] The assembly positioning hole can be used for positioning when the shaft coupling sleeve and the motor rotor are docked and installed, which facilitates the installation and docking operation.

[0012] As a preferred technical solution of the utility model, a circular curved surface 1 is formed on the inner side of blade 1, a circular curved surface 2 is formed on the outer side of blade 1, and the curvature radius of circular curved surface 2 is greater than the curvature radius of circular curved surface 1. A blade blade is formed at one end of blade 1 close to the outer edge of the rear disc, and the transverse cross-section of the blade blade is a hemispherical structure. The guide sleeve is composed of an air inlet tube and a guide tube, and the inner diameter of the guide tube gradually decreases from the air inlet tube to the guide tube.

[0013] The flow resistance can be reduced by optimizing the surface finish of the blade and using fluid dynamics optimized blade surface treatment technology. By optimizing the flow channel shape, the turbulence and resistance in the flow channel can be reduced, thereby increasing the fluid throughput.

[0014] As an optimal technical solution of the utility model, the wheel disc and the shaft connecting sleeve are concentrically arranged, and a plurality of blades are arranged circumferentially with equal intervals around the axis of the wheel disc. The wheel disc is located on the inner side of the guide sleeve, and the structural dimensions of the blades are matched with those of the guide sleeve.

[0015] The rotation of blade 2 drives the air flow to flow along the air duct constructed by the guide sleeve. During the air flow flowing along the guide sleeve, the inner diameter of the guide tube gradually decreases, so that the flow velocity of the air flow gradually increases, thereby improving the heat dissipation rate.

[0016] As a preferred technical solution of the utility model, the dynamic balancing adjustment assembly includes a dynamic balancing frame and a counterweight plate. The dynamic balancing frame is an arc-shaped structure. An adjustment slot is provided on the dynamic balancing frame. The counterweight plate is slidably connected to the adjustment slot via a slider. The counterweight plate is provided with fastening bolts.

[0017] By adjusting the position of the counterweight plate on the adjusting slot, the center of gravity of the impeller can be made to coincide with the main axis, thereby achieving the purpose of balance.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] It can be connected to the motor rotor structure through the shaft sleeve. As the motor rotor rotates, the rear disc can rotate synchronously. When the rear disc rotates, it can drive the surrounding air through blade one, and make the air flow inward along the air duct constructed by blade one. The symmetrical design of blade one can reduce the fluid resistance and energy loss. At the same time, blade two can further drive the air flow at the end of the rear disc, thereby increasing the air flow and improving the heat dissipation efficiency. The dynamic balancing adjustment component can be adjusted according to the operating conditions of the rear disc when it rotates synchronously on the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

At the same time, the airflow flowing on the inner side of blade 2 forms a low-pressure area inside the rear disc 1, so that the inward flow resistance of the airflow driven by subsequent blade 2 601 is reduced. The symmetrical design of blade 2 can reduce the resistance and energy loss of the fluid. At the same time, blade 2 601 can further drive the air flow at the end of the rear disc 1, thereby increasing the air flow and improving the heat dissipation efficiency. The dynamic balancing adjustment component can be adjusted according to the operating conditions of the rear disc 1 when it rotates synchronously on the rotor.

[0031] Specifically, the rear disc 1 and the blade 1 2 are concentrically arranged, and an assembly positioning hole 8 is opened on the rear disc 1. The assembly positioning hole 8 can be used for positioning when the shaft sleeve 5 is docked with the motor rotor, which facilitates the installation and docking operation.

[0032] Specifically, a circular curved surface 1 201 is formed on the inner side of blade 1, a circular curved surface 202 is formed on the outer side of blade 1, and the curvature radius of circular curved surface 202 is greater than the curvature radius of circular curved surface 1 201. A blade blade 203 is formed at one end of blade 2 close to the outer edge of rear disc 1, and the transverse cross-section of blade blade 203 is a hemispherical structure. Guide sleeve 4 is composed of air inlet cylinder 401 and guide cylinder 402. The inner diameter of guide cylinder 402 gradually decreases from air inlet cylinder 401 to guide cylinder 402. The flow resistance is reduced by optimizing the surface finish of blade 2 and adopting fluid dynamics optimized surface treatment technology of blade 2. By optimizing the shape of flow channel, turbulence and resistance in the flow channel can be reduced, thereby increasing the fluid throughput.

[0033] Specifically, the wheel 6 and the shaft connection sleeve 5 are concentrically arranged, and a plurality of blades 601 are arranged in a circle with equal intervals around the axis of the wheel 6. The wheel 6 is located on the inner side of the guide sleeve 4, and the structural dimensions of the blades 601 and the guide sleeve 4 are adapted to each other. The rotation of the blades 601 drives the airflow to flow along the air duct constructed by the guide sleeve 4. In the process of the airflow flowing along the guide sleeve 4, the inner diameter of the guide tube 402 gradually decreases, so that the flow velocity of the airflow gradually increases, thereby improving the heat dissipation rate.

[0034] Specifically, the dynamic balancing adjustment component includes a dynamic balancing frame 7 and a counterweight plate 702. The dynamic balancing frame 7 is an arc-shaped structure. An adjustment slot 701 is provided on the dynamic balancing frame 7. The counterweight plate 702 is slidably connected to the adjustment slot 701 via a slider. A fastening bolt 703 is installed on the counterweight plate 702. By adjusting the position of the counterweight plate 702 on the adjustment slot 701, the center of gravity of the impeller can be made to coincide with the main axis, thereby achieving the purpose of balance.

[0035] Working principle: First, it can be connected to the motor rotor structure through the shaft sleeve 5. As the motor rotor rotates, the rear disc 1 can rotate synchronously. While the rear disc 1 rotates, it can drive the surrounding air through the blade 1 2, and make the air flow inward along the air duct constructed by the blade 1 2. The symmetrical design of the blade 1 2 can reduce the resistance and energy loss of the fluid. At the same time, the blade 2 601 can further drive the air flow at the end of the rear disc 1, thereby increasing the air flow and improving the heat dissipation efficiency. The dynamic balancing adjustment component can be adjusted according to the operating conditions of the rear disc 1 when it rotates synchronously on the rotor. It is practical through The flow resistance can be reduced by optimizing the surface finish of blade 2 and using fluid dynamics optimized blade 2 surface treatment technology. By optimizing the flow channel shape, the turbulence and resistance in the flow channel can be reduced, thereby increasing the fluid throughput. The airflow can be driven by the rotation of blade 2 601 to flow along the air duct constructed by the guide sleeve 4. In the process of the airflow flowing along the guide sleeve 4, the inner diameter of the guide tube 402 gradually decreases, so that the flow velocity of the airflow gradually increases, thereby improving the heat dissipation rate. By adjusting the position of the counterweight plate 702 on the adjusting groove 701, the center of gravity of the impeller can coincide with the main axis to achieve the purpose of balance.
