Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic oil heat dissipation, in particular to a forced air cooling oil heat dissipation device for wind power equipment. BACKGROUND

[0002] With the gradual depletion of energy such as coal and oil, humans pay more and more attention to the use of renewable energy. Wind energy, as a clean and renewable energy, is increasingly valued by countries around the world. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that lack water, fuel and transportation, it is very suitable and promising to use wind power generation according to local conditions. In some extreme weather conditions, such as high temperature, high humidity, sandstorm and the like, the heat dissipation capacity of air may decrease, resulting in that the temperature of lubricating oil cannot be effectively controlled. Especially in summer high temperature or sandstorm weather, the forced air cooling system may face the situation of insufficient cooling capacity

[0003] In the Chinese patent with the publication number CN118481933A, a forced air cooling oil heat dissipation device for wind power equipment is disclosed. When it is necessary to dissipate heat of hydraulic oil, the air suction pump and the refrigeration tank are started, the external air is sucked into the refrigeration tank through the air suction cover, and the cold air is sprayed out of the air outlet branch pipes through the air outlet main pipe and the spray head. The cold air can be uniformly sprayed into the inner cavity of the tank through the ventilation hole, so as to cool the hydraulic oil in the tank. At the same time, the cooperation of the heat dissipation fan, the first and second heat dissipation fins can form a multi-directional strong air duct in the inner cavity of the tank, so that the heat emitted from the hydraulic oil tank can be quickly transferred out, thereby quickly dissipating heat of the hydraulic oil, effectively avoiding accumulation of heat in the hydraulic oil, and protecting the wind power equipment and prolonging the service life of the wind power equipment.

[0004] When the existing equipment is used, the hydraulic oil plays a role of energy transmission, wear resistance, system lubrication, corrosion prevention, rust prevention, cooling and the like in the hydraulic system. When the wind power equipment is operated for a long time, the hydraulic oil in the hydraulic system will gradually heat up. At this time, the cooling equipment is needed to cool the hydraulic oil. Otherwise, the long-time heating of the hydraulic oil will cause deterioration of the hydraulic oil, which is not conducive to the use of the equipment and reduces the service life of the equipment. At the same time, the hydraulic oil in the hydraulic equipment cannot control the circulation efficiency, so that the cooling effect is poor. Therefore, the forced air cooling oil heat dissipation device for wind power equipment is developed. SUMMARY
