Beschreibung
Zusammenfassung:	The invention discloses an integrated cooling system for a gearbox frequency converter of a wind turbine generator. The integrated cooling system comprises a frequency converter cooling cycle, a gearbox cooling cycle and a pump-driven two-phase heat dissipation cycle. The frequency converter cooling cycle is composed of the frequency converter, a micro-channel heat exchanger, a circulating pump, a liquid storage tank and a plate heat exchanger. The gearbox cooling cycle system is composed of a gearbox, an oil pump and the plate heat exchanger. The pump-driven two-phase heat dissipation cycle is composed of the circulating pump, a plate-fin condenser and the plate heat exchanger. The frequency converter cooling cycle, the gearbox cooling cycle and the pump-driven two-phase heat dissipation cycle share one plate heat exchanger. The plate heat exchanger is provided with three fluid channels, and the frequency converter cooling cycle, the gearbox cooling cycle and the pump-driven two-phase heat dissipation cycle
