Cooling Fan Series [upscale all-steel fan Features] 1. durable, green, high dielectric strength; 2. the appearance of smooth, beautiful, generous, smooth exterior shell, not to hurt the hand never rust; 3. High strength, aging, easy to break, fade Changchun cooling fan, anti-corrosion, anti-acid, enhances the fan life, increased 3-5 times higher than the metal material can be used for 20 years lifetime fan cooling fan cooling principle is: when the fan is running Yancheng negative pressure into the cavity cooling fan winds, so the outside-air flow through the porous moist wet curtain surface forces the curtain air dry bulb temperature dropped to close to the machine outside air wet bulb temperature of the cooling fan Weifang chicken, namely the cold outlet dry bulb temperature bulb temperature low 5-12 ℃ (dry heat areas up to 15 ℃), the more air is dry and hot, the temperature difference, the greater the cooling effect is better than the outdoor dry. Yancheng wind cooling fan, cooling fan, Qingzhou Minhua Qingzhou temperature control equipment supplied by Chinese citizens thermostat plant.
