The invention discloses a wind driven generator cooled by a tower barrel wall, which belongs to the technical field of wind power generation. The generator is characterized by comprising a coolant tank (23) and a tower barrel cooler (18), wherein the coolant tank (23) is arranged at the bottom of a tower barrel; one end of the tower barrel cooler (18) is connected with the inlet of the coolant tank, and the other end of the tower barrel cooler (18) is connected with a liquid return pipe (2); the outlet of the coolant tank is connected with a liquid inlet pipe (1) through a circulating pump (21); a heater (22) is also arranged in the coolant tank (23); and the tower barrel cooler (18) is a cooling channel which is used for dissipating heat by using the tower barrel wall. Compared with the conventional wind driven generator cooling system, the generator has the prominent advantages of high heat exchange capability, small volume, low mass and the like and is easy and convenient to mount and maintain.
Description
Technical field [0001] The invention relates to a wind power generator utilizing tower wall cooling, and belongs to the technical field of wind power generation. Background technique [0002] With the advancement of science and technology and the adjustment of the national energy strategy, as one of the main methods of renewable energy utilization, wind power has become an important part of the national energy supply, and the wind turbine with a single capacity of MW is the main force for the development of wind power. trend. Due to the increase in power generation, the calorific value of a single wind turbine has also increased from tens of kilowatts to hundreds of kilowatts, which puts forward increasingly stringent requirements on the cooling system, and has become an obstacle to the development of wind turbines with larger capacity. One of the technical problems of development. Although the research on wind turbine cooling technology has made great progress in recent y...
