220V Cooling Fan option

In the "220V Cooling Fan" of choice, we tend to compare pressure and wind, air pressure and air flow rate for normal ventilation. Ventilation fan to overcome resistance within travel, cooling fan must overcome the air resistance generated pressure. This is the pressure. Pressure is a measure of "220V Cooling Fan" an important indicator of performance. Pressure depends on the shape of the fan blade, area, height and speed, the faster the speed, the greater the fan. Relatively greater pressure, duct heat sink design also better able to maintain the fan pressure. Cooled air flow is sent or inhalation of the total volume of air per minute in the same heat sink material, the air flow is a measure of the most important indicators of air-cooled heat sink capability. "220V Cooling Fan" the greater the larger the amount of wind greater air volume per unit of time can take more heat.
