220V AC Cooling Fan radiator selection

Under air-cooled case "220V AC Cooling Fan" For radiator actually choose a specific system, may have a variety of radiator solution, you can choose a small radiator next larger airflow velocity conditions, you can choose large radiator airflow velocity at smaller environments. The higher the air velocity, the greater the noise generated by a fan, but these "220V AC Cooling Fan" disadvantages can be obtained by a small system size to compensate. It is worth noting: When the flow rate is greater than 7m / s, almost never to reinforce the cooling effect. When the system power is only required cooling equipment, you can also use a radiator with a fan. In the case of forced convection, natural convection and select "220V AC Cooling Fan" radiator radiator under selection method is similar. Although the fluid temperature in determining how much of the resistance is important, but not a major factor in selecting a radiator, air velocity is the only choice radiator
