Embodiment Construction

[0031] 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.

[0032] 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. The power module 2 can be tiled inside the nacelle of the wind power generating set, for example, can be directly installed on the inner wall of the nacelle.

[0033] 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...

Abstract

The invention discloses a conversion system, a heat dissipation device and a wind generating set. The conversion system comprises a plurality of power modules, the power modules are paved inside a cabin of the wind generating seat; a radiator is arranged on each power module; and the conversion system also comprises a heat dissipation device for carrying out heat dissipation on the radiators by using an external air flow. Through the conversion system, the power modules are installed inside the cabin, so that a converter body is omitted, the using amount of cables is reduced, and the 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...
