1. Regular inspection and cleaningDuring long-term operation, DC brushless centrifugal fans may be affected by the accumulation of dust, dirt or other impurities in the air, which may affect their normal operation. Therefore, regular cleaning of the fan is the key to ensuring its efficient operation. Cleaning the fan blades: The fan blades are one of the core components of the fan. Dust and impurities can cause the fan blades to be unbalanced, causing vibration and noise. You can use a soft brush or compressed air to gently remove dust from the fan blades. If necessary, wipe the fan blades with a non-corrosive detergent, but avoid using too wet cloth. Cleaning the motor: Dust accumulation inside the DC brushless motor may affect its heat dissipation effect and cause the motor temperature to be too high. It is recommended to use clean compressed air to blow away dust from the outside of the motor regularly, but avoid blowing air directly into the motor to avoid damaging the motor windings. Cleaning the filter: If the fan is equipped with a filter, it should be cleaned regularly. The function of the filter is to prevent external impurities from entering the fan, but over time, the filter is prone to dust accumulation. Regularly dismantle and clean the filter to keep the fan ventilated smoothly. 2. Lubrication and bearing maintenanceDuring long-term use, the bearings of DC brushless centrifugal fans may wear due to friction, resulting in increased noise, unsmooth operation or jamming. Therefore, it is very important to lubricate and maintain the bearings regularly. Lubrication method: Different types of fans use different types of bearings. Some bearings use a closed structure and do not require lubrication; while some fans require regular oiling. For bearings that require oiling, use the lubricating oil or grease recommended by the manufacturer to avoid using unsuitable lubricating materials. Lubrication cycle: The lubrication cycle should be determined according to the use environment and load conditions of the fan. Generally speaking, the lubrication cycle should be appropriately shortened for fans used in high-load or high-temperature environments. The specific lubrication cycle can be determined according to the fan manual. Bearing inspection: Regularly check the bearings for abnormal noise or vibration. If the bearing is severely worn or damaged, it should be replaced in time to avoid affecting the normal operation of the fan. 3. Electrical system inspectionDC brushless centrifugal fans are usually equipped with electronic controllers, sensors and power supply systems. These electrical components may cause fan failure due to aging, damage or current fluctuations. Therefore, the inspection and maintenance of the electrical system is also crucial. Check the power supply and wiring: Regularly check whether the power supply voltage is stable to ensure that the fan can work normally at the rated voltage. Check whether the wiring is loose or worn to avoid poor contact that causes the fan to fail to start or excessive current. Check the motor controller: The controller of the DC brushless fan is responsible for regulating the speed and operating status of the motor. Failure of the controller may cause the fan to work abnormally. Regularly check the working status of the controller, including whether there is overheating, abnormal sound or alarm indication, and repair or replace it in time. Battery maintenance: If the fan is equipped with a built-in battery (such as some emergency fans or DC fans in mobile devices), it is necessary to regularly check the battery power and status to avoid battery aging or leakage affecting the normal operation of the equipment. 4. Check the balance and vibration of the fanThe balance of the fan directly affects the stability of its operation. If the blades are worn or damaged, it may cause the fan to run unbalanced, resulting in unnecessary vibration and noise, and even damage to other components. Therefore, it is crucial to keep the fan balanced. Balance the blades: Check whether the blades are worn, cracked or deformed. If the blades are found to be damaged, they should be replaced in time. When replacing, make sure that the weight and shape of the new blades match the original blades to maintain the balance of the fan. Bearing and installation inspection: The vibration of the fan may also be related to the looseness of the bearings and mounting parts. Regularly check whether the bearings are intact and ensure that all mounting screws and connectors are firmly tightened to avoid vibration caused by looseness. Use vibration detection tools: For some equipment with high precision requirements, the use of vibration detection tools can more accurately determine the balance of the fan. If the vibration is too large, it should be adjusted or repaired in time. 5. Prevent overheating Overheating is one of the common causes of failure of DC brushless centrifugal fans. Long-term high-load operation, high ambient temperature or poor cooling system may cause the motor temperature to be too high, affecting the performance of the fan and even causing damage. Ensure good ventilation and heat dissipation: Make sure that the fan's heat dissipation holes and air inlets are unobstructed. Regularly check the environment around the fan to avoid accumulation blocking the fan's heat dissipation channel. Reduce load operation: Try to avoid the fan running under overload for a long time. If the fan is often under high load, it may cause the motor temperature to be too high. The workload should be reasonably arranged according to the design parameters of the fan. Use temperature control device: Some high-end DC brushless centrifugal fans are equipped with temperature control devices that can automatically monitor the temperature and adjust the fan speed. Regularly check whether the temperature control system is working properly and ensure that the temperature is not too high. 6. Regularly detect and replace faulty partsWith the extension of the use time, some parts of the DC brushless centrifugal fan may age or be damaged. Regularly detecting and replacing faulty parts can effectively prevent sudden failures. Motor winding inspection: Regularly check whether the motor winding is aging, burning, etc. If the motor performance is found to be degraded or faulty, it should be repaired or replaced in time. Capacitor inspection: If the capacitor of the fan motor fails, the motor may not start normally. Check the working status of the capacitor regularly to ensure that it is within the normal working range. Replace wear parts: For example, bearings, fan blades, controllers and other parts will have certain wear after long-term use. If wear parts are found, they should be replaced in time.

1. Core components of thermal management systems 1. Battery coolingOne of the core components of electric vehicles and hybrid vehicles is the power battery pack. These batteries generate a lot of heat during the charging and discharging process. If the heat cannot be dissipated in time, it will lead to battery performance degradation, shortened life, and even safety issues such as thermal runaway. The DC centrifugal fan can quickly remove the heat around the battery pack through its efficient airflow generation ability, and discharge it outside the vehicle through a heat exchanger or cooling system to ensure that the battery pack operates within the optimal temperature range. 2. Drive motor heat dissipationThe drive motors of electric vehicles and hybrid vehicles also require good heat dissipation. The motor generates a lot of heat energy when working, especially at high speeds or high load conditions. The DC centrifugal fan can effectively remove this heat from the motor housing and windings to prevent the motor from overheating and ensure the stability and reliability of the motor. 3. Control system coolingThe electronic control systems of electric vehicles and hybrid vehicles (such as vehicle controllers, battery management systems, etc.) also need heat dissipation. These systems integrate a large number of electronic components and integrated circuits and are sensitive to temperature. By providing a stable airflow, DC centrifugal fans can ensure that these systems will not fail due to overheating when running at high loads. 2. Specific application examples 1. Battery thermal management systemIn the battery thermal management system of electric vehicles and hybrid vehicles, DC centrifugal fans are usually used in combination with liquid cooling systems or air cooling systems. In liquid cooling systems, fans help coolant circulate between the battery pack and the radiator, taking heat away from the battery pack and dissipating it into the air. In air cooling systems, fans blow directly onto the surface of the battery pack and take away heat through air convection. 2. Drive motor cooling moduleThe drive motor cooling module usually includes components such as motor housing, radiator, fan and temperature sensor. The DC centrifugal fan is installed on one side or above the radiator to accelerate the heat dissipation efficiency of the radiator by blowing air. At the same time, the fan speed can be intelligently adjusted according to the temperature of the motor to achieve more precise heat dissipation control. 3. Cabin ventilation and air conditioning assistanceIn addition to the core heat dissipation application, DC centrifugal fans can also be used for cabin ventilation and air conditioning assistance of electric vehicles and hybrid vehicles. In hot weather, fans can help speed up the flow of air in the cabin and improve the cooling efficiency of the air conditioner. In cold weather, fans can assist the heating system and transfer heat to the cabin faster. 3. Technology Development Trends 1. Intelligence and IntegrationWith the improvement of automobile electronics and intelligence, DC centrifugal fans are also developing in the direction of intelligence and integration. Fans in modern cars are usually equipped with intelligent sensors and controllers, which can automatically adjust the speed and wind direction according to the actual needs of the vehicle and the working environment to achieve more precise heat dissipation control. At the same time, the integration of fans and vehicle control systems is also constantly improving, providing a more convenient and efficient solution for vehicle thermal management. 2.
