The water pump drives water to circulate, and uses water as a medium for heat exchange to dissipate heat for certain components of the wind turbine. Generally, large wind turbines will use a converter, which is a large rectifier and inverter. The device has a high calorific value. If it is not dissipated in time, it will easily burn out and cause unnecessary losses. Therefore, a water-cooling device is needed for heat dissipation
The size of the wind turbine is not critical.
The key is whether the wind speed in your local area is strong. If the wind speed is strong enough, then the power generation will be more.
If the wind is too small, there is no need to install wind power generation.
The electricity generated by wind turbines is generally stored in batteries. You can use the electricity saved for a day to carry large electrical appliances, or you can carry small-power electrical appliances. The amount of electricity generated is limited, so the more powerful an appliance is, the less time it will be used.
