Description

technical field [0001] The invention relates to the technical field of high towers of wind turbines, in particular to a ventilation cooling performance configuration method, device and tower for high towers. Background technique [0002] The converter and other electrical components in the wind turbine tower will generate a lot of heat during operation, and ventilation and cooling design is required to achieve effective heat dissipation. At present, the wind turbine tower usually directly relies on the chimney effect of hot air and the tower arm to achieve ventilation and cooling, or uses the ventilation and heat dissipation structure of the air-cooled converter itself in the high tower tower, that is, through the reasonable arrangement of the components of the cabinet To enhance the ventilation and cooling of the converter, but the heat exchange capacity of the above method is limited, the high-temperature gas generated during the operation of the converter cannot be cooled...

AI Technical Summary

Problems solved by technology

For the ventilation and heat dissipation performance of the high tower, the ventilation and heat dissipation structure of the original tower is usually used directly at present, that is, the heat dissipation system configured by the ventilation and heat dissipation mode of the traditional ordinary height tower is directly used. As the height increases, the heat transfer area of ​​the tower increases, and the external heat transfer capacity of the tower wall increases, so the high tower can improve the ventilation and heat dissipation performance to a certain extent, but due to the increase of the tower, the hot air emitted by the converter rises At the same time, the path will also increase and the resistance will increase. If the ventilation and heat dissipation structure of the original tower is used directly, the hot air discharged from the converter will accumulate on the first layer of the tower and cause the temperature to rise, and the high tower structure is not conducive to the heat dissipation of the tower. The timely discharge makes the ventilation and cooling performance poor, and when the ambient temperature is too high, it is easy to cause problems such as excessive local temperature in the space inside the tower.

[0004] In order to solve the above-mentioned technical problems of the high-rise tower, adding equipment such as cooling fans in the tower can improve the ventilation and cooling performance, but the air volume and heat dissipation of the cooling fans are different, and the ventilation and cooling generated in the entire elevated tower The effect is also different. If the layout position and air volume of the cooling fan do not match the air volume entering and exiting the tower, the air in the upper layer will be poured back from the elevator hole to the lower layer, so that the cooling fan needs to do more work, but the ventilation and cooling performance is still poor.
