(Summary description)How to choose a DC cooling fan? Selection steps DC cooling fans are mostly used in intelligent devices, new energy devices, charging stations, etc., with voltages of 12V, 5V, 24V, 48V, and are selected based on the power supply voltage of the equipment. In addition, the size of the DC fan is selected based on the limited installation space of the equipment, the speed and air volume are selected based on the heat output of the equipment, and the functions required for the fan support of the adaptive equipment must be verified whether this fan support is supported or not How to choose a DC cooling fan? How can I choose a DC fan that is suitable for my device? For many equipment manufacturers, choosing the right fan is not as simple as choosing the right size and voltage on the surface. A suitable DC fan must have good heat dissipation effect, stable operation, long service life, moderate noise, complete functional support, and so on. Below, to simplify the process, how to quickly select the right DC fan. The first step in selecting a DC fan is to narrow the fan size range. For example, the approximate size reserved for the device is 100mm. When selecting a fan size, it must be smaller than this size, and the range should be locked within 20mm smaller than this size, which is 80mm-100mm. Alternatively, according to the device type, for example, if the device is a charging station, the charging station usually uses a size of 120-172mm, and the projector usually uses a size of 40-60mm, The fan sizes used by these two devices are basically the same, so choose to narrow the size range based on the device type. The second step of selecting a DC fan is to determine the air volume of the DC fan. The air volume is related to the size and speed of the fan. After determining the size in the first step, the air volume is calculated based on data such as equipment heat output and temperature rise, and the formula is used to select the air volume. Usually, a DC fan is divided into several voltages and the air volume is also divided into four levels. Choose the appropriate air volume. If there is no detailed data here, generally choose a medium speed for testing, If this size cannot meet the heat dissipation requirements, increase the thickness of the fan appropriately to increase the air volume. For example, a 40mm DC fan with multiple thicknesses of 10, 15, 20, and 28mm can be selected. The third step of selecting a DC fan is to determine the voltage selection and support functions. Normally, a DC fan with the same air volume has multiple voltage options, such as a 9238 DC fan with a speed of 4000RPM, which can be selected as 12v24v48v. Furthermore, in terms of support functions, if your device needs to have a PWM speed regulation and RD operation monitoring function, determine whether to support these functions after determining the voltage. AC fans generally do not support these functions. The fourth step in selecting a DC fan is to determine the characteristics of waterproofing, noise, working temperature, and material used. Why do we put these four parameters together? DC fans are used in a variety of devices, including damp environments, bedrooms, computer rooms, and special experimental environments. The waterproof level includes IP65, IP67, and IP68. The noise varies according to the specific model of the DC fan, and the working temperature is generally -10-70 ℃. The materials used include metal plastic, ball bearings, oil bearings, etc These are all selected based on the usage environment, such as the DC fan used for heat dissipation of special equipment in the laboratory. The experimental environment is complex and occasionally comes into contact with water, and equipment maintenance is difficult. Based on this situation, it is necessary to choose high-level waterproof to deal with occasional contact with water. Roller bearings have a longer lifespan and are more stable than oil bearings. Choosing ball bearings to meet the problem of difficult equipment maintenance and reduce the failure rate of DC fans In summary, when selecting a DC fan for special scenarios, the fourth step should be considered as the first step for screening. After meeting the special needs, the size, voltage, supporting functions, air volume, etc. should be determined Capital Technology Co., Limited is the chief agent of SANYO DENKI, one of the leading enterprises of the cooling fan industry.
