Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to a heat dissipation device for wind power equipment. Background Art

[0002] Wind power generation equipment is a device that converts wind energy into electrical energy. Wind power equipment mainly includes wind turbines and their related accessories and auxiliary equipment. In the actual application of wind power equipment, wind turbines are the core equipment. The performance of the heat dissipation device directly affects the operating efficiency and service life of the equipment. The heat dissipation is mainly concentrated in places such as generators and gear boxes.

[0003] Existing heat dissipation devices for wind power equipment mainly rely on air cooling for heat dissipation, but there are some significant problems in the actual operation process. First, the filter of the air cooling device will accumulate a lot of dust and impurities after long-term use, resulting in a gradual decrease in the amount of air entering, which in turn affects the heat dissipation efficiency. Since the filter cannot be cleaned during the operation of the equipment, once the filter is blocked, the heat dissipation effect will be greatly reduced, and may even cause the equipment to overheat and be damaged. Secondly, existing heat dissipation devices usually adopt a fixed filter design, which is very inconvenient to maintain and clean. It needs to be shut down and disassembled for cleaning, which not only increases the maintenance cost, but also affects the continuous operation of the equipment.

[0004] Therefore, it is necessary to provide a heat dissipation device for wind power equipment to solve the technical problems raised in the above background technology. Summary of the invention

[0005] In view of the above problems, the present invention provides a heat dissipation device for wind power equipment, which dissipates heat to the component structure of the wind power equipment through the condenser tube in the condensing heat sink. At the same time, the condenser tube in the air intake and heat dissipation assembly forms a loop with the condenser tube in the condensing heat sink and the oil tank pump pressure assembly. The heat dissipation unit draws in external cold air and cools the hydraulic oil in the condenser tube in the air intake and heat dissipation assembly, and the hot air is discharged from the exhaust unit. The hydraulic oil has a high specific heat capacity and thermal conductivity, and can quickly absorb the heat generated by the equipment and transfer it to the condenser tube in the condensing heat sink, thereby realizing efficient heat dissipation of the equipment components. The condenser tube in the air intake and heat dissipation assembly can ensure that the heat can be quickly transferred from the hydraulic oil to the air, thereby improving the heat dissipation efficiency, and can regularly clean and maintain the heat dissipation unit and the exhaust unit, thereby ensuring the normal inflow and outflow of airflow and the overall heat dissipation effect.
