Wind power generating set, heat dissipation system and heat dissipation control method thereof

Abstract

The invention discloses a wind generating set and a heat dissipation system and a heat dissipation control method thereof. The heat dissipation system comprises an impeller heat dissipation device and a cabin heat dissipation device, wherein the impeller heat dissipation device is mounted in a cabin of the wind generating set; hot air in a hub of the wind generating set passes through an air guide tube and is introduced into the impeller heat dissipation device; heat exchange between the hot air and a fluid medium in the impeller heat dissipation device is carried out; the cabin heat dissipation device is mounted in the cabin; the hot air in the cabin is sucked into the cabin heat dissipation device; and heat exchange between the hot air in the cabin and the fluid medium in the cabin heat dissipation device is carried out. By the heat dissipation system, an impeller system and the cabin are subjected to heat dissipation simultaneously, and meanwhile, a heat dissipation process is automatically controlled intelligently according to temperature change.

Description

technical field [0001] The invention relates to the field of wind power generation, and in particular, the invention relates to a wind power generating set, a heat dissipation system and a heat dissipation control method thereof. Background technique [0002] In some wind power generating sets, the cooling system for cooling the nacelle is installed outside the nacelle, and the heat in the nacelle is transferred to the heat exchanger outside the nacelle for heat dissipation through pipelines. This saves space inside the nacelle and can reduce the size of the nacelle. However, since the heat exchanger is installed obliquely outside the nacelle, the effective area for heat exchange is actually relatively small, requiring a large number of heat exchangers, which will adversely affect the appearance of the wind turbine. [0003] In addition, the heat dissipation system set up in this way can only cool the cabin space, but cannot simultaneously cool the interior space of the imp...

Problems solved by technology

However, since the heat exchanger is installed obliquely outside the nacelle, the effective area for heat exchange is actually relatively small, requiring a large number of heat exchangers, which will have a bad influence on the appearance of the wind turbine

[0003] In addition, the heat dissipation system set up in this way can only cool the cabin space, but cannot simultaneously cool the interior space of the impeller system and keep the interior within a suitable temperature range

At the same time, this kind of heat dissipation system cannot realize intelligent control, but adjusts the heat dissipation method according to the temperature of the surrounding environment.
