Abstract
A nacelle cooling system of a wind turbine has cooling blocks which are arranged in order to respectively surround one or more heating devices installed inside a nacelle, a passage pipe line which is connected to the cooling blocks for coolant to flow, a primary heat exchanger which is connected to the passage pipe line and arranged on the outer lateral surface of the nacelle so as to seal the nacelle from outside, and a secondary heat exchanger which is capable of discharging heat generated inside the nacelle into outside the nacelle and constructed to seal the nacelle from outside.
Claims4
A nacelle cooling system for a wind turbine including a nacelle which has a gearbox and a generator to perform wind power generation, a blade which is mechanically coupled to the gearbox, and a tower which is provided such that the nacelle is seated on a top thereof, the nacelle cooling system comprising:
- cooling blocks placed, respectively, to surround one or more heat generating devices which are provided in the nacelle;
- a passage pipe coupled to the cooling blocks so that coolant flows through the passage pipe;
- a primary heat exchanger coupled to the passage pipe, and disposed on an outer surface or a rear end of the nacelle;
- and
- a secondary heat exchanger comprising a refrigerant circulating between an inside of the nacelle and an outside of the nacelle so as to discharge heat generated in the nacelle into the outside of the nacelle,
- wherein the primary heat exchanger and the secondary heat exchanger are constructed to seal the nacelle from the outside,
- wherein the heat generating devices comprise at least one selected from a group including a generator, a gearbox, and an inverter, and
- wherein the primary heat exchanger performs a heat exchange process between the coolant flowing through the passage pipe and external air.
