Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the present invention, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] refer to Figure 1 to Figure 3 According to an embodiment of the present invention, a nacelle of a wind generating set is provided. The nacelle of the wind generating set has a windward side and a leeward side, usually, the windward side is the head, and the leeward side is the tail. Wheel hubs, generators, gearboxes and various electrical mechanisms are usually installed in the engine room. The hub is generally installed at the front in the nacelle, and the generator, gearbox and electrical mechanism are installed at the rear of the hub. For the rear area of ​​the nacelle where components such as generators are installed, it generally includes top panels, bottom panels, side panels and tail panels connected to each other.

Abstract

The invention discloses an engine room and a wind generating set. A part of a wall surface, being surrounded by flowing external airflow, of the engine room is formed as an inclined part. The inclinedpart protrudes outward, the height of the inclined part being gradually increased, from the windward side of the engine room to the leeward side. A plurality of power modules are mounted inside the inclined part, and radiators are connected to the power modules. The engine room of the wind generating set improves the heat dissipation of the power modules in a converter and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular, the invention relates to a nacelle of a wind power generating set and the wind power generating set. Background technique [0002] On the wind power generating set, the converter is usually packaged in the form of a cabinet, and multiple power modules are installed in the same cabinet to form a separate converter cabinet. The converter cabinet is generally installed at the bottom of the tower of the wind power generating set, and is connected to the generator through multiple low-voltage cables (generally 690V) with a certain length. Since a large amount of heat is generated in the converter cabinet when the generator generates electricity, a cooling system is generally arranged around the power module in the converter cabinet to dissipate heat and finally dissipate the heat to the outside of the tower. in the atmosphere. [0003] At present, the converter cabinet generally a...
