Why do some cooling fans use impellers, while others use impellers?

Do you want to ask the question: “Why do some cooling fans use wind turbines and others use turbines, which one is better? » The difference between the two is:

Wind wheel: usually has a higher rotation speed and a higher volume of air, so it is more efficient in providing energy stronger wind turbine and better cooling effect. Used in locations requiring greater air volume and space, such as industrial cooling equipment or large machinery. Due to their high rotation speed, wind turbines can produce higher sound levels, requiring additional soundproofing measures.

Wind turbine: Compared to wind turbines, wind turbines generally offer lower noise levels and are suitable for locations that require a quiet environment, tels as offices or bedrooms. The usual rotation speed is lower, so it consumes less energy and has the advantage of energy saving. Due to the high design flexibility of the wind turbine, manufacturers can change its shape and size as needed to achieve different wind power and air volume.

What is an alternator windshield?

Large wind fan refers to wind turbine.

Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally include a wind wheel, a generator, a. director, it is composed of a tower, a speed limit safety mechanism and an energy storage device.

The operating principle of a wind turbine isrelatively simple. The wind wheel rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. driving the wind wheel shaft to produce electricity.

Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a working fluid.

Wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy intended to replace human and animal energy. The widespread application of electromechanical power in modern times and the discovery of oil deposits in the Middle East in the 1950s slowed the development of wind turbines.

Generator principle:

The principle of energy productionWind power is to use wind energy to rotate the blades of the windmill, and then increase the rotation speed. using a speed multiplier to cause the generator to produce electricity. With current wind turbine technology, electricity generation can begin at a breeze speed of around three meters per second (the level of a light wind).

Due to the unstable air volume, the wind turbine produces 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.

The generator will generate a lot of heat when it rotates for pgenerate electricity, and the cold air needs to pass between the stator and rotor, so there will be fan blades at one end of the generator, and the high-speed fan blades will blow the cooling air.It There should be a grid-like net (mostly circular and closed) on the outside, which is the windshield of the generator, which protects the fan blades to prevent objects from falling on the fan blades.
