The 5V Mini DC Axial Flow Fan is a micro ultra-small heat dissipation fan developed for portable mini electronic devices and low-power precision equipment. It adopts 5V USB universal DC voltage supply, with ultra-compact size, ultra-low power consumption, ultra-quiet operation and plug-and-play convenience, filling the market gap of heat dissipation for tiny miniature equipment. Different from conventional large and medium-sized fans, this mini fan is designed for small-space heat dissipation scenarios, with a miniaturized overall structure, light weight, and no space occupation, which can be flexibly installed in various compact and portable electronic products without affecting the overall structure and appearance of the equipment.

In terms of power supply and energy saving, the 5V working voltage is the most common universal low voltage for civilian electronic products, compatible with USB power supply interfaces, mobile power supplies, computer USB ports, and low-voltage power adapters. It realizes plug-and-play use without complex wiring and voltage conversion equipment, which is extremely convenient for daily use and equipment matching. The fan’s power consumption is extremely low, with the rated power only 0.5W-2W. It can work continuously for a long time with very low energy consumption, which will not cause excessive power load on portable equipment and fully meet the energy-saving design requirements of mini electronic products.

In terms of structural and performance design, the 5V mini DC axial flow fan adopts a micro brushless motor core, which has the characteristics of small volume, low heat generation and stable operation. The ultra-fine precision impeller is made of high-toughness lightweight plastic, which can rotate efficiently at high speed with low friction and low noise. The conventional rotating speed range is 3000-6000 RPM, and the matched micro air volume can accurately meet the small heat dissipation demand of mini equipment, avoiding the problem of excessive wind force and unnecessary power waste caused by large fans. The whole fan is equipped with a mute shock absorption pad, which can eliminate the vibration noise generated by high-speed rotation. The operating noise is controlled below 30dB, realizing silent heat dissipation and will not cause noise interference to the use environment.

This mini fan has extremely wide application scenarios in civilian portable electronic equipment and small precision products. It is widely used in mini industrial computers, portable projectors, USB cooling brackets, small LED light boxes, Bluetooth audio equipment, miniature monitoring equipment, handheld testing instruments, smart home small equipment, and notebook computer auxiliary heat dissipation. For these tiny devices, although the heat generation is small, the closed and compact space is easy to cause heat accumulation, resulting in slow equipment operation, short circuit failure and shortened service life. The 5V mini DC axial flow fan can conduct real-time micro-air convection heat dissipation, maintain the internal temperature balance of mini equipment, and ensure the stable and efficient operation of portable precision electronic products. Its advantages of low price, convenient use, small size and energy saving make it the most mainstream heat dissipation accessory for mini low-power electronic equipment.
