Title:
ACTIVE AIR-WATER COUPLING COOLING SYSTEM IN TOWER BOTTOM
Document Type and Number:
WIPO Patent Application WO/2018/192563
Kind Code:
A1
Abstract:
An active air-water coupling cooling system in tower bottom, which realizes an active air cooling circulation in tower bottom by configuring an active air cooling device in tower bottom, and a water cooling circulation by a water cooling device in tower bottom. The active air cooling device is used to control temperature of some heat sources such as the box-type transformer (2) in tower bottom and the frequency converter(4), the water cooling circulation is used to control temperature of the large heat flux density elements in the frequency converter (4), and the air and water cooling circulations can be combined to achieve an accurate control of the ambient temperature and humidity in tower bottom. The air-water coupling cooling system intower bottom features all advantages of air cooling system and water cooling system i.e. stable operation, low cost and effective. The air-water coupling cooling system combines the air cooling system and the water cooling system, and it is significant for onshore high-capacity wind turbine set to operate stably with low cost.
