  • 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.

    In the design of vehicle evaporator blowers, noise control technology has always been one of the focuses of research and development. As consumers' requirements for car ride comfort increase, the control of vehicle interior noise has become more and more important. 1. Active noise control technologyActive noise control technology is the widely used technology in the design of vehicle evaporator blowers in recent years. Its principle is to detect the noise generated by vehicle evaporator blowers through sensors, and generate a sound wave with the opposite phase and the same amplitude as the noise in real time, so that the two cancel each other out in physical space, thereby achieving the purpose of reducing noise. This technology is particularly effective for low-frequency noise, because low-frequency noise has a longer wavelength and is easier to eliminate through sound wave interference. In the design of vehicle evaporator blowers, active noise control technology is usually implemented in combination with digital signal processing technology (DSP). Through the DSP chip, the noise signal collected by the sensor can be processed in real time, and the corresponding anti-phase sound wave can be quickly generated. In addition, with the continuous development of intelligent control technology, active noise control technology can also be integrated with other systems of the vehicle (such as navigation system, in-vehicle entertainment system, etc.) to achieve more intelligent noise control. 2. Passive noise control technologyAlthough active noise control technology has significant effects, passive noise control technology still plays an important role in certain frequency ranges. Passive noise control technology mainly reduces the propagation of noise by adopting sound-absorbing materials, sound insulation structures, etc. In the design of vehicle evaporator blowers, the application of passive noise control technology is mainly reflected in the following aspects: Optimization design of vehicle Evaporator Blowers shell: By optimizing the structure of the blower shell, its sound insulation performance is increased and the propagation of noise to the outside is reduced. Application of sound-absorbing materials: Use sound-absorbing materials such as porous foam plastics, glass fiber, etc. inside or around the blower to absorb noise and reduce its intensity. Design of soundproof cover: Set a soundproof cover outside the blower to reduce the impact of noise on passengers by isolating the propagation path between the noise source and the receiver. 3. Application of new materials and technologiesIn addition to the two main noise control technologies mentioned above, some new materials and technologies have also been applied in the design of vehicle evaporator blowers. Using new materials such as carbon fiber composite materials and nanomaterials to manufacture the blower housing can improve its strength and sound insulation performance; using advanced aerodynamic design to optimize the airflow distribution of the blower can reduce the noise it generates; using intelligent sensing and control systems to monitor and adjust the operating status of the blower in real time to achieve more refined noise control. Noise control technology plays an important role in the design of vehicle evaporator blowers. By combining active noise control technology and passive noise control technology, as well as applying new materials and technologies, the noise generated by the vehicle evaporator blower can be effectively reduced and the riding comfort of passengers can be improved.

    Optimizing the performance of the refrigeration system is a complex and critical process, in which the adjustment of the operating parameters of the Evaporator Fans plays a vital role. As an important part of the refrigeration system, the operating status of the Evaporator Fan directly affects the refrigeration effect and energy efficiency of the system. 1. Understand the main operating parameters of the Evaporator FansThe main operating parameters of the Evaporator Fans include speed, air volume, pressure, temperature, etc. Among them, the speed determines the number of revolutions of the fan blades per unit time, which directly affects the size of the air volume; the air volume determines the volume of air passing through the evaporator per unit time, which has a direct impact on the refrigeration effect; pressure and temperature are important parameters for measuring the operating status of the fan. Too high or too low pressure and temperature may affect the performance and life of the fan. 2. Adjust the operating parameters of the Evaporator Fans according to actual needsSpeed ​​adjustmentThe speed is one of the important parameters of the Evaporator Fan. The appropriate speed can ensure that the fan maintains low energy consumption while providing sufficient air volume. In actual operation, the speed of the Evaporator Fans can be appropriately adjusted according to the load of the refrigeration system and the ambient temperature. When the load is heavy or the ambient temperature is high, the speed can be appropriately increased to increase the air volume to improve the cooling effect; otherwise, the speed can be reduced to reduce energy consumption. Air volume adjustmentAir volume is one of the key factors affecting the cooling effect. When adjusting the air volume, it is necessary to comprehensively consider factors such as the load of the refrigeration system, the evaporator area, and the refrigerant flow rate. Generally speaking, when the load of the refrigeration system is large, the air volume needs to be increased to improve the heat exchange efficiency of the evaporator surface; when the load is small, the air volume can be appropriately reduced to reduce energy consumption. Pressure adjustmentEvaporator Fans will be affected by a certain pressure during operation. Too high or too low pressure may affect the performance and life of the fan. Therefore, when adjusting the operating parameters of the evaporator fan, it is necessary to pay attention to the pressure of the fan. The pressure distribution of the fan can be optimized by adjusting the structure of the fan's air inlet, air outlet, and air duct to ensure that the fan operates under appropriate pressure. Temperature adjustmentTemperature is one of the important indicators for evaluating the performance of the refrigeration system. When adjusting the operating parameters of the evaporator fan, it is necessary to pay attention to the temperature of the fan. The fan's operating temperature can be reduced and its stability and life can be improved by increasing or reducing the fan's heat dissipation area and optimizing the heat dissipation structure. 3. Regularly inspect and maintain the evaporator fanFan blade inspection: Check whether the fan blades are damaged, deformed or loose. The integrity of the blades directly affects the fan's air volume and efficiency. Motor inspection: Check whether the motor's operating sound is normal and whether there is abnormal vibration or overheating. The normal operation of the motor is the key to the stable operation of the fan. Bearing inspection: Check the lubrication of the bearings to see if there is wear or jamming. Good lubrication of the bearings can ensure that the fan runs smoothly and with low noise. Electrical connection inspection: Check whether the electrical connection of the Evaporator Fans is firm and whether the wires are damaged or aged. The safety and reliability of the electrical connection is the basis for ensuring the normal operation of the fan. Protective cover and air inlet inspection: Check whether the fan's protective cover is intact and whether there is blockage or foreign matter in the air inlet. The protective cover can protect the fan from external damage, and the unobstructed air inlet can ensure that the fan obtains sufficient air flow.Clean the blades and guards: Clean the dust and dirt on the Evaporator Fan blades and guards regularly to keep them clean. This can improve the efficiency of the fan and extend its service life. Replace worn parts: For worn or damaged parts found during the inspection, such as blades, bearings, etc., they should be replaced in time. This can avoid the expansion of faults and ensure the normal operation of the fan. Lubricate the bearings: For the bearing part, lubricating oil or grease should be added regularly to ensure that it is well lubricated. This can reduce the wear and noise of the bearing and improve the operating efficiency of the fan. Tighten the electrical connection: For the electrical connection part, it should be checked and tightened regularly to ensure that the connection is firm and reliable. This can prevent the occurrence of electrical faults and ensure the safe operation of the fan. Check the operating status of the Evaporator Fans regularly: By monitoring the speed, air volume, temperature and other parameters of the Evaporator Fans, you can understand whether the operating status of the fan is normal. If abnormalities are found, they should be handled and adjusted in time.
