Wind means "220V Cooling Fan" exhaust or the total volume of air per minute included, if calculated according to cubic feet, the air volume unit is CFM; if you press m to count, that is CMM. Air volume fan unit is often used CFM (about 0.028 m3 / min). Air flow is a measure of the most important indicators of "220V Cooling Fan" cooling capacity. Obviously, the greater the amount of air cooling fan its cooling capacity is also higher. This is because the heat capacity of the air ratio is constant, the greater the amount of wind, which is more air per unit of time can take away more heat. Of course, under the same "220V Cooling Fan" in the case of the cooling effect of wind and wind flow the way.
