  • 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.

  • 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.

    As a power device that relies on voltage power supply to generate airflow, the operation of the blower is based on the basic principle of electromagnetic induction and magnetic field interaction. It converts electrical energy into mechanical energy by constructing a specific electromagnetic system, thereby achieving efficient driving of airflow. Unlike ordinary fans, blowers adopt a more complex and precise structural design to meet the stringent requirements for airflow intensity, stability and continuity under different working conditions. ​Precise electromagnetic drive structure​The core structure of the blower consists of an electromagnet stator and a permanent magnet rotor. The coils wound on the stator are key components for energy conversion. When current passes through these coils, a magnetic field is generated around the stator according to the law of electromagnetic induction. The permanent magnets on the rotor themselves have a fixed magnetic field. Under the action of the stator magnetic field, according to the principle of interaction between magnetic poles, the permanent magnet rotor will be driven by electromagnetic force. This electromagnetic force breaks the static state of the rotor, prompting it to start rotating, gradually converting electrical energy into mechanical energy of the rotor, thereby driving the entire device to operate and providing continuous power for airflow generation. This ingenious electromagnetic drive structure design not only ensures the high efficiency of energy conversion, but also lays the foundation for the stable operation of the blower. ​Careful design ensures high efficiency and reliability​The blower motor is strictly controlled from design to processing to achieve its performance.

Through this careful design and precision processing, the blower motor has the remarkable characteristics of low noise, high efficiency, long life and stable performance. The low noise characteristic makes it suitable for occasions with strict requirements on environmental noise; high efficiency ensures that a stronger airflow can be output at the same energy consumption; long life and stable performance reduce the maintenance cost and failure risk of the equipment, and improve the overall use value. ​Wide and diverse application fields​With its performance, blowers have been widely used in many fields. In the field of electronic equipment, as the integration of chips continues to increase, the heat generated by the equipment during operation increases dramatically. Blowers are used in the heat dissipation system of electronic equipment. By quickly circulating air, the heat inside the equipment is promptly removed, ensuring that the electronic components work in a suitable temperature environment, and improving the stability and service life of the equipment.

The motor adopts efficient permanent magnet synchronous motor technology, which has higher energy conversion efficiency than traditional motors, and reduces the loss of electric energy during transmission and conversion. By optimizing the electromagnetic design and air duct structure of the motor, the wind resistance and electromagnetic loss during motor operation are reduced, and the energy utilization efficiency is further improved. The motor control system has an intelligent energy-saving mode, which can automatically adjust the motor power according to the actual cooling needs. On the premise of meeting the cooling effect, it can minimize energy consumption and save operating costs for users. ​Reliable and stable long-term operation guarantee​In terms of ensuring long-term stable operation, the evaporator fan motor is designed and optimized from multiple dimensions.

The protection level of the motor reaches the industry-leading level, which can effectively resist the erosion of external factors such as dust and water vapor, adapt to various complex use environments, achieve long-term stable operation, and reduce the maintenance frequency and cost of equipment. ​Flexible and intelligent speed control system​The adjustable speed control system equipped with the evaporator fan motor gives the product a high degree of flexibility and intelligence. The system can monitor parameters such as ambient temperature and equipment operating status in real time, and automatically adjust the fan speed according to the preset control logic. When the ambient temperature is low or the equipment load is small, the system automatically reduces the fan speed to reduce energy consumption and noise; when the ambient temperature rises or the equipment load increases, the system promptly increases the fan speed to enhance the cooling effect. Users can also accurately set the fan speed according to actual needs through manual adjustment or remote control to meet personalized cooling needs under different working conditions and achieve refined management of the cooling system.
