What exactly is an electronic fan? What is an electric fan?

The function of the cooling fan is to increase the air velocity and volume through the radiator. to improve the heat dissipation capacity of the radiator. The fan is usually mounted behind the radiator and positioned as closely as possible in the center of the radiator core.

Fans can be divided into mechanical fans and electric fans.

Machinery is a fan. It is directly driven by the engine power, in order to reduce the power loss and save fuel engine, the fan control device is mostly used to control the connection and separation of the cooling fan and the drive belt disc, so that the fan does not work all the time when the engine is running.

There are three commonly used fan control devices: hydraulic clutch, automatic clutch and hydraulic coupling.

Electric fan, at present, many cars use electric fans, the work of the electric fan system is controlled by the thermal switch, when the engine temperature is low, the fan does not rotate, when the engine temperature rises, the fan rotates, some electric fans have high and low speed gears, when the engine temperature is slightly higher, the fan runs in low gear, and when the engine temperature is high, the fan runs quickly to dissipate heat.

Electric fan, also known as fan and fan, is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate the circulation of air, mainly used to cool off the heat and circulate the air. It is widely used in homes, classrooms, offices, shops, hospitals and hotels.

A fan is mainly composed of components such as a fan head, blades, grille, and controls. The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism. The main components of an electric fan are:

AC motors. Its working principle is: the energized coil is rotated by Sun Xun force in the magnetic field.

Electrical energy is converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that a part of the electrical energy will be converted into thermal energy by turning the sail.

Common household fans are essentially axial fans, i.e., the direction of the wind is parallel to the axis of rotation of the fan blades.

The electric fan is used to cool down in summer, and it really helps you look forward to it.

An electrical appliance that is driven by an electric motor to make the air flow move.

The main differences are:

1. Different dynasties have different attitudes: In ancient times, the original function of the fan was not to cool off, but to show the ruling class to show their status and privileges. Because fans are mostly found in the palace, fans are also called "palace fans".

At this time, literati were also not available, and the royal family was exclusive.

After the Sui and Tang dynasties, the fan was regarded as a "sleeved elegant thing", so if the literati and artists did not have a fan in their hands, it was like a petty bourgeoisie who did not keep a pet dog, which seemed a little tasteless. Therefore, it is mostly used by literati at this time.

But in the Qing Dynasty, not only the literati and ink writers of Zaila, but even the **, Mr. Bookkeeper, and even all kinds of people at the bottom of the society also liked to shake the fan to "pose".

2. Different classes use different types of fans: folding fans used by literati and ink writers, goose feather fans gently swayed by military advisors, group fans used by maids and ladies, and big pu fans used by peddlers.

The working principle of the electronic fan is that the car electronic fan is controlled by the thermostat, when the water temperature rises to the upper limit value of the thermostat is connected to the power supply, the fan starts to work, and when the water temperature is reduced to the lower limit value of the thermostat to turn off the power supply, the fan stops working; Here are the reasons why the electronic fan doesn't turn:

1. The motor is poorly lubricated and the electric fan does not rotate, which means that the lubrication of the motor is not good, resulting in the motor not being able to drag after the fan blade is installed;

2. The motor is overheated, and the motor overheating will also cause the motor to deteriorate the mold load capacity with negative envy, and the effective power of the motor will become low, resulting in the inability to drive the load;

3. The starting capacitance capacity becomes smaller, and the capacitor capacity will become smaller, resulting in the starting torque of the motor becoming smaller, and the load cannot be driven;

4. If the motor is used for a long time, if the electric fan is used for a long time, the motor will be lost, and the shaft of the motor will be worn out, and it will be easy to burn off. If the motor is used for a long time, the internal resistance of the motor will also become larger, and the load capacity will be lower, resulting in the inability to drive the fan blade to rotate.

Electric fan, referred to as electric fan, is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate air circulation, mainly used to cool off the heat and circulate air. It is widely used in homes, offices, shops, hospitals, hotels and other places. The electric fan is mainly composed of parts such as a fan head, fan blades, a grille and a control device.

The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism. Fan.
