Rotary cooling system of wind driven generator and wind driven generator with same

Abstract

The invention discloses a rotary cooling system of a superconducting wind driven generator. The system comprises at least one heat exchange unit attached to the outer peripheral wall of an iron core cylinder of an outer rotor of the superconducting wind driven generator. Each heat exchange unit comprises a filter, a cooling fan, a heat exchanger and a heat exchanger shell, wherein the filter is arranged at the end of the heat exchange shell, a plurality of filter holes are evenly distributed in the surface of the filter, the cooling fan is arranged at the rear end of the filter and communicated with an inner cavity of the heat exchanger shell, the heat exchanger shell is axially attached to the outer wall of the iron core cylinder, a plurality of heat dissipation holes are formed in the surface of the heat exchanger shell and can be communicated with through holes formed in the outer wall of the iron core cylinder, heat is exhausted out of an outlet in the other end of the heat exchanger shell, and then convection cooling is achieved. The invention further discloses the wind driven generator with the cooling system. Forced ventilation caused by rotation of superconducting motor blades can be fully utilized, a cooling path inside a superconducting motor is shortened to a certain degree, and efficiency of cooling fans of the superconducting motor and efficiency of the whole superconducting motor are improved.
