Description

Technical Field

[0001] The utility model relates to the field of fan heat dissipation, in particular to a heat dissipation device for reducing the fire risk of a fan. Background Art

[0002] Fast-growing tree species such as poplars and drought-resistant willows that are drought-tolerant and saline-alkali-tolerant are commonly planted in the northern coastal areas. A large amount of catkins, poplar floss, and dust fly everywhere in late spring and early summer every year. At this time, it is the season of strong winds and high temperatures. A large amount of catkins, poplar floss, and dust will enter the fan and block the heat dissipation filter screen, and high-temperature warnings in the engine room occur frequently.

[0003] The heat dissipation of the engine room and the gearbox is realized through the heat dissipation fan at the top of the gearbox. The heat exchanger (radiator) is constructed in a honeycomb mesh shape. Through the suction generated by the operation of the heat dissipation fan, the heat in the engine room is discharged into the atmosphere, and at the same time, the oil temperature of the gearbox can also be reduced. Since some equipment models are not high-temperature resistant models, there are defects in ventilation heat dissipation and unit sealing. The heat dissipation fan in the engine room discharges air from the inside to the outside, making the inside of the engine room in a negative pressure state. Dust and willow catkins in the air enter the engine room through the gaps. Due to the relatively high air humidity by the sea, dust is extremely easy to adhere to the honeycomb grid channels. Coupled with the relatively high temperature of the radiator, the dust adheres and quickly forms a scab, blocking the ventilation duct. The willow catkins entering the engine room are also adsorbed on the surface of the radiator under the suction of the fan. Under the combined action of dust and willow catkins inside and outside, the radiator is severely blocked, resulting in the inability to discharge heat in time, causing the gear oil temperature to be too high and the unit to shut down.

[0004] Especially in the spring with high temperature and strong winds, the heat generated by the high-load operation of the fan accumulates inside the engine room. The blocked radiator cannot discharge heat in time, resulting in large-scale shutdown or load-limiting operation. At the same time, the high temperature causes the components inside the fan to age rapidly, such as fatigue damage of the motor bearings, insulation damage of the wires due to overheating, accelerated aging of electrical components due to high temperature, and accelerated aging of the oil pipe sealing rings due to high temperature, seriously affecting the availability of the fan and the service life of the equipment, and even may cause the fan to catch fire, which is not conducive to the working safety of the fan.

[0005] In response to the above problems, one of the existing solutions is to customize a filter screen according to the actual environment of the site to isolate willow catkins, board the plane to clean the filter screen before and after the high-incidence period of willow catkins every spring, and also clean the filter screen during each regular inspection and maintenance. This solution isolates willow catkins in the simplest way, greatly reducing the probability of radiator blockage and the cleaning difficulty of maintenance personnel. However, it is necessary to board the plane multiple times every spring, the overhaul interval of the fan is short, and if the cleaning is not timely, it will lead to high-temperature shutdown. Moreover, only willow catkins are isolated, and dust still enters the radiator through the filter screen, resulting in serious scabbing of the radiator.

[0006] Another existing solution is to use a high-pressure water gun for cleaning. This solution has a good cleaning effect. After cleaning, the dust and scale on the radiator are significantly reduced, and the heat dissipation effect in the engine room is good. However, the labor intensity is relatively large, the downtime during cleaning is relatively long, and the power loss of the equipment is large. Summary of the Invention
