Novel cooling device for wind driven generator

Abstract

The invention discloses a novel cooling device for a wind driven generator. The novel cooling device comprises a machine shell; a heat dissipation opening and a heat dissipation hole are formed in the bottom and one end of the shell correspondingly; a power generation device is arranged in the shell; a rotating shaft is arranged in the power generation device; the two ends of the rotating shaft stretch out of the two ends of the power generation device; one end of the rotating shaft penetrates the end portion of the machine shell to be connected with fan blades; first heat dissipation blades are arranged at the bottom of the power generation device and are in engaged connection with one end of the rotating shaft through an acceleration gear set; a drive gear is arranged at the end portion of the other end of the rotating shaft and is connected with second heat dissipation blades through an acceleration gear structure; and the second heat dissipation blades right face the heat dissipation hole in the end portion of the machine shell. According to the cooling device, cold air is sucked in through the first heat dissipation blades to cool the interior of the machine shell, airflow obtained after heat exchange is dissipated out through the second heat dissipation blades, and effective cooling of the interior of the machine shell is achieved; and in addition, power of the rotating shaft is used for cooling and power generation at the same time, the utilization rate of wind energy is greatly increased, and the utilization efficiency of energy is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a novel cooling device for wind power generators. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. The wind rotor converts the kinetic energy of the wind into mechanical energy. As an important component, the wind rotor consists of several blades. [0003] When the wind blows to the blades of the wind rotor, aerodynamic force is generated on the blades to drive the wind rotor to rotate and drive the generator to generate electricity. During the operation of the generator, the heat generated by the main gearbox and the generator is very large, and some models change The current collector is also in the nacelle, and the heat will be greater. If the temperature of the nacelle cannot be lowered, the heat transfer efficiency will ...

[0003] When the wind blows to the blades of the wind rotor, aerodynamic force is generated on the blades to drive the wind rotor to rotate and drive the generator to generate electricity. During the operation of the generator, the heat generated by the main gearbox and the generator is very large, and some models change The current collector is also in the nacelle, and the heat will be greater. If the temperature of the nacelle cannot be lowered, the heat transfer efficiency will be reduced, and the continuous high temperature will affect the operating life of the equipment. The existing cooling device cannot effectively cool the electricity inside the wind turbine nacelle The unit is cooling down, and the working stability of the cooling device is poor, which seriously affects the power generation efficiency
