Description

TECHNICAL FIELD

[0001] The utility model relates to cooling fan technical field, especially in auxiliary cooling fan of factory transformer. BACKGROUND

[0002] The auxiliary cooling fan of transformer is a device for enhancing the heat dissipation capacity of the transformer, which is usually installed on the radiator or cooler of the transformer. When the load of the transformer increases or the ambient temperature rises, the heat generated inside may exceed the heat dissipation capacity of natural cooling. At this time, the auxiliary cooling fan starts to work, accelerating heat dissipation through forced air flow, ensuring that the temperature of the transformer remains within a safe range, thereby ensuring stable operation and prolonging the service life.

[0003] Most of the cooling fans on the market often have problems of air backflow, reduced air intake at the air inlet end, and poor heat dissipation performance due to pressure difference between the air inlet end and the air outlet end when reaching high speed. In addition, vibration and noise problems occur during high-speed rotation, greatly reducing the user experience of the equipment. Noise also affects the environmental quality of people's production and life. Moreover, the vibration caused by fan rotation can damage the equipment, and long-term exposure to a vibrating environment can cause parts to loosen or even accelerate the wear and tear of components. Therefore, achieving high speed and low vibration often requires improving the precision of equipment processing and installation, which increases production costs and is not conducive to cost reduction.

[0004] The existing patent (publication number: CN216131130U) discloses a low-noise cooling fan. The cooling fan includes a fan housing, a bearing fixing sleeve fixed at the center of the inside of the fan housing, a motor stator fixedly installed outside the bearing fixing sleeve, a rotating shaft provided inside the bearing fixing sleeve through a bearing, a rotor housing fixedly connected to the upper end of the rotating shaft through a rotating shaft fixing seat, and a motor rotor provided inside the rotor housing corresponding to the position of the motor stator. The cooling fan improves the concentricity of the bearing by setting the bearing fixing sleeve, reduces vibration during rotation of the bearing and rotating shaft, and thus reduces noise. In addition, the vibration reduction structure of the fan can greatly reduce the generation and transmission efficiency of vibration, thereby reducing noise.

[0005] To solve the above problems, the existing patent provides a solution. However, the existing auxiliary cooling fan for factory transformer has the problem of dust accumulation, which aggravates equipment wear and tear, leading to a significant increase in failure rate. Frequent maintenance not only increases costs but also increases the number of equipment downtime for repair. At present, most cooling devices have poor cooling effect, making it difficult to maintain stable operation of the transformer, resulting in frequent faults and defects, and making it difficult to ensure long-term safe operation of the equipment. Operation adjustment and maintenance are also difficult, which seriously restricts the safety and economy of the power supply system.

[0006] To this end, the auxiliary cooling fan of the plant transformer is provided. Content of the utility model
