Embodiment Construction

[0059] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0060] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "first", "second", "third" and "fourth" are for the purpose of clearly explaining the numbering of product parts, and do not mean any material difference. "Before" and "after" are based on the conventional understanding of product structure. For example: the direction of the shroud is the front, and the direction of the nacelle cover is the rear. "Up" and "Down" refer to the directions shown in the attached drawings. "Installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connec...

Abstract

The invention relates to the field of cooling, in particular to a heat dissipation system and method of a wind generating set and the wind generating set. The heat dissipation system comprises draught fans, one or more wind inlet portions installed on the outer wall of a flow guiding hood and a wind outlet portion installed at the tail of a cabin hood; and the draught fans are installed on the wind inlet portions, and the wind inlet portions are located in front of a hub. The heat dissipation method utilizes the heat dissipation system, and the wind generating set comprises the heat dissipation system. The draught fans draw air outside the wind generating set into the wind inlet portions, and positive pressure air flows are formed in the wind inlet portions, flow into the flow guiding hood and are divided after being guided by the flow guiding hood and the hub so as to cool a stator upper winding and rotor upper magnetic steel, a stator lower winding and rotor lower magnetic steel and a bearing and a base of the engine. In this way, positive pressure is guided into the air flows, and the air flows are divided in the set for cooling all components in the set, and the cooling efficiency and effect are improved.

Description

technical field [0001] The invention relates to the field of cooling, in particular to a cooling system for a wind power generating set, a heat dissipation method and a wind generating set. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. During the operation of the wind turbine, the internal components, such as generators, electrical components, and power devices, will generate more heat, and the temperature in the engine room is relatively high, which needs to be dissipated in time. [0003] At present, various researches and attempts have been made on heat dissipation in this field. Some researchers have installed air heat exchangers on the top of the nacelle and the tower to achieve the purpose of cooling the air in the nacelle by exchanging heat with the cold outside air. This method does not take into account the problem of cooling t...
