"Micro Cooling Fan" is the gas compression and gas transportation machinery habit of short, commonly referred to include through cooling fan cooling fan, drum fan. Gas compression and gas transportation machinery is the rotation of the mechanical energy is converted to gas pressure and kinetic energy, and gas transfer out of machinery. "Micro Cooling Fan" base with motor inside the air intake fan base, bladeless fan, through the cyclone accelerator, from the inside outward blowing fan fan head annular lip. The US public bladeless fan power consumption low, an ordinary fan energy consumption by half. In addition, because of the "Micro Cooling Fan" without a fan, for the curious nature of children do not have harm, and easier to clean than conventional air conditioning and fan, bladeless fan production.
