The Miniature 3010 DC Axial Fan is an ultra-small, ultra-thin precision heat dissipation component with a size of 30mm × 30mm × 10mm, specially designed for micro and mini electronic equipment with extremely limited installation space. With the miniaturization and high integration of modern electronic products, traditional large-size cooling fans can no longer meet the heat dissipation needs of miniature precision equipment. The 3010 miniature DC axial fan fills the market gap of micro heat dissipation solutions with its ultra-compact size, lightweight design, and precise heat dissipation performance, and is widely used in various small and medium-sized low-power electronic devices. In terms of structural design, the 3010 miniature fan adopts a mini integrated molding process. The ultra-small frame and micro aerodynamic blades are precisely designed through micro fluid dynamics simulation, which can efficiently gather air flow and realize directional heat dissipation in a tiny space. The whole machine weighs only a few grams, with ultra-light load, and will not cause structural pressure on miniature electronic equipment. The fan’s shell and blades are made of high-purity anti-aging PBT plastic, which has good insulation, flame retardant, and anti-deformation properties, ensuring stable structural performance during long-term micro-vibration operation. In terms of performance characteristics, this miniature DC axial fan mainly supports low-voltage specifications of 5V and 12V, which are perfectly matched with the power supply voltage of miniature consumer electronics and precision instruments. The rotating speed ranges from 4000 RPM to 12000 RPM. Although the size is small, the air volume and wind pressure are precisely matched with the heat generation of micro equipment, which can quickly take away the tiny heat accumulated inside precision components and avoid equipment failure caused by local overheating. The brushless DC micro motor adopted by the fan has the advantages of low power consumption, low noise, and no electromagnetic interference. The operating power is as low as 0.5W to 1.5W, which will not increase the power consumption burden of miniature low-power equipment. The optimized bearing system uses high-precision micro oil-impregnated bearings, with ultra-low operating noise, basically no audible noise during operation, meeting the silent working requirements of precision instruments and smart wearable devices. In terms of safety and stability, the 3010 miniature fan has built-in intelligent protection circuits, with over-current, over-voltage, and locked-rotor protection functions. When the fan is accidentally stuck or short-circuited, it can automatically power off and protect, avoiding damage to precision electronic equipment. The product passes strict micro-vibration aging test and high and low temperature cycle test, and can work stably in the environment of -20℃ to 60℃, with a service life of up to 35,000 hours, meeting the long-term service life requirements of miniature electronic products. In terms of application scenarios, the Miniature 3010 DC Axial Fan covers a wide range of micro heat dissipation fields, including smart wearable devices, miniature sensors, Bluetooth audio equipment, portable chargers, small LED lamps, medical miniature instruments, smart home micro-control modules, and drone electronic components. For precision micro-equipment that pursues small size, light weight, low noise and low power consumption, this fan is the most ideal heat dissipation solution. In addition, the fan has simple wiring, convenient installation, low cost, and complies with RoHS environmental protection standards, which can meet the mass production and sales needs of various miniature electronic products, and is a core supporting component in the field of micro electronic thermal management.
