The small size of WHEE miniature fan solves the problem of space-limited product that need extra heat dissipation. Forced convection of hot air is formed inside the confined airframe, and cold air is introduced to effectively reduce the heat source.

DC fan is a micro cooling fan that small in size but high in efficiency and low in power use. Micro DC fan is available for OEM and ODM Service as well. Find specially designed miniature fans supplied by the cooling fans manufacturer from China.

Advantages of Micro DC Fans

The inside of the small dc fan mostly uses high-efficiency permanent magnets. After the power is turned on, the drive shaft drives the fan blades through the principle of electromagnetic effect, which greatly reduces the frictional kinetic energy consumption generated when the fan is running. This also makes the noise emitted by the small dc motor fan can be as low as 15 decibels, and the power consumption is only one-third of the traditional AC fan, and the number of air volume adjustment stages is generally more than that of the AC fan.
