Embodiment Construction

[0017] In the vertical axis wind power generator provided by the present invention, the permanent magnet generator used is an ironless disc structure generator. Such as figure 1 As shown, the generator is packaged in a closed space enclosed by the central shaft 1 and the end cover 6, in which the stator part and the rotor part are in the form of planar disks and arranged in the axial direction. The stator part is mainly composed of an armature clamp 3 and an armature 7, wherein the armature clamp 3 is fixed around the central axis 1, and the armature 7 extends radially. The rotor part includes two symmetrical rotor disks up and down, and a bearing 2 is installed between the rotor disks and the central shaft 1 . A yoke 4 is also provided at the outer edges of the upper and lower rotor discs to form a closed magnetic circuit. A plurality of permanent magnets 8 with alternating magnetic poles are arranged on the two rotor disks, and these permanent magnets are arranged in a rin...

Abstract

The invention discloses a heat abstractor for a high-power vertical-axis wind generating set. In the heat abstractor, an air passage penetrates the flat clearance at the middle of an end cover, and at least one air feeder/exhaust fan is arranged in the air passage. In addition, a plurality of air holes are penetratively arranged on an armature of a stator, and a plurality of air holes are penetratively arranged on a permanent magnet of a rotor disk. The hear abstractor has good radiating effect, greatly reduces critical temperature inside a wind generator, effectively avoids local overheating, and is beneficial to development of the vertical-axis wind generator towards the trend of high power.

Description

technical field [0001] The invention relates to a heat dissipation device for a high-power vertical axis wind power generator, and also relates to a wind power generator using the heat dissipation device, belonging to the technical field of wind power generation. Background technique [0002] Wind energy is the most promising renewable energy besides water energy, and has been highly valued by countries all over the world. China has become the most active wind power market in the world. In 2009, the installed capacity of new wind power in the country exceeded 8 million kilowatts, and the cumulative total capacity has reached more than 20 million kilowatts. Therefore, the market prospect of my country's wind power equipment manufacturing industry and related fields is very broad. [0003] Wind turbines are classified according to the direction of the rotation axis, which can be divided into two types: horizontal axis and vertical axis. At present, the horizontal axis wind ...
