  • Evaporationr Fan

    An evaporative fan, also known as an evaporative air conditioner or wet cooler, is a device used to reduce ambient temperature. They cool the surrounding air by evaporating moisture, providing an energy-efficient and environmentally friendly air conditioning solution, especially suitable for dry and hot climate conditions. Evaporative fans use the evaporation principle of water to cool the air. During the evaporation process, a fan blows hot air through a water medium (usually wet filter paper or fluffy humidified fiber), so that the heat in the air is used to evaporate water, thereby cooling the air. This process lowers the temperature of the air while increasing its humidity. Evaporative fans typically consume less electrical energy than traditional refrigeration systems because they do not require compressed refrigerant. Additionally, evaporative fans do not emit harmful chemicals, making them environmentally friendly.

  • Blower
    Blower

    A blower is a fan that uses a special voltage supply to drive the blower's rotor to create airflow. It usually consists of an electromagnet stator and a permanent magnet rotor. The coils on the stator generate a magnetic field through electric current, while the permanent magnets on the rotor are acted upon by a fixed magnetic field. When current passes through the stator coil, the force generated by the magnetic field rotates the rotor, thereby driving the equipment to operate. The blower motor is precisely designed and machined to ensure its efficiency and reliability. It usually has low noise, high efficiency, long life and stable performance. Blower motors are widely used in various fields, such as electronic equipment cooling, automobile ventilation, industrial production, etc.

  • Motor

    A brushed motor is a common type of DC motor with a relatively simple structure that uses brushes and brushes to transmit current to a rotating part to produce mechanical motion. A brushed motor consists of a rotating part called the rotor and a stationary part called the stator. The rotor usually includes permanent magnets, while the stator includes coils. Brushes and brushes are attached to the stator and they are in contact with the electronic slip rings of the rotating part so that current can enter the rotating part. The brushes are a conductive material, usually made of carbon or carbide, that are tightly attached to the stator along with the brushes (also called brush holders). The brushes pass current to the rotating part by contacting the collector ring (usually on the rotating part), thereby creating a magnetic field interaction and inducing rotational motion.
