If the chassis, under the power of a large windmill "24V DC Cooling Fan" directly into the wind from the outside of the chassis, power supply will be very cool, is conducive to stable power, long life, but dust will be relatively large; small fan power will not very cool, but it will not become cleaner. Some people like to set under a large windmill "24V DC Cooling Fan" supply anti-wear, are interested can try. For fanless power supply, the positive pressure in the duct of the chassis, most of the heat will be discharged to the outside of the chassis; suction duct within the chassis, most of the heat will be discharged to the chassis. And no fan "24V DC Cooling Fan" power of a large number of openings chassis air duct design will bring some inconvenience, need special attention. Industrial cooling equipment must be products, including now the phone is the same, the cooling effect is particularly vulnerable to bad crash.
