Description

technical field

[0001] The invention relates to the technical field of wind power generation, in particular to a circulating cooling device for a wind power double-fed generator. Background technique

[0002] With the gradual reduction of resources, people have discovered more power generation methods. Among them, wind power generation is widely used in places with abundant wind resources due to its advantages of low cost, high safety, and no pollution.

[0003] Wind power generation equipment mainly relies on wind doubly-fed generators for power generation. In order to ensure the normal operation of wind doubly-fed generators, they need to be cooled by wind doubly-fed generator cooling devices during their use. However, most of the existing wind doubly-fed generator cooling devices are air-cooled heat dissipation, which has low heat dissipation efficiency and easily causes electrical components to be damaged by high temperature.
