Embodiment Construction

[0032] 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.

[0033] refer to figure 1 , according to an embodiment of the present invention, a converter system for a wind power generating set is provided. The converter system may include a plurality of power modules 2, each power module 2 may be provided with a radiator 21, and the power module 2 and the radiator 21 may be integrally formed as a single component.

[0034] Generally, for the nacelle of a wind turbine, it has a head and a tail. When the wind turbine is running, the external airflow or wind flows from the head of the nacelle to the tail, that is to say, the head of the nacelle is the windward side, and the tail for the leeward side. Wheel hubs, generators, gearboxes and various electrical mechanisms are usually installed in the engine room. The hub i...

Abstract

The invention discloses a current conversion system, a heat dissipation apparatus, and a wind power generator set. The current conversion system comprises a plurality of power modules; the multiple power modules are tiled in an engine room of the wind power generator set; a radiator is arranged on each power module; the current conversion system also comprises an air channel structure; and the airchannel structure can guide external air flow to the interior of the engine room and enable the air flow to flow through the radiators to perform heat dissipation. By virtue of the current conversionsystem, the power modules are mounted in the engine room, so that a current conversion cabinet body is omitted, dosage of cables is lowered, and heat dissipation of each power module is improved.

Description

technical field [0001] The invention relates to the assembly and cooling of electronic devices, in particular, the invention relates to a flow conversion system, a cooling device and a 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...
