Optional cooling fans need some common sense
Optional cooling fans need some common senseFirst, buy the general knowledge of the cooling fan:In the purchase of fans generally have to understand the following necessary information:★ fan size.★ determine whether the fan is DC or communication.★ fan supply voltage value. For example: AC 220V, 110V, 380V. DC 5V, 12V, 24V, 36V, 48V.★ fan bearing form, ball or oil.★ fan air volume, speed. For example, how many cubic meters per minute, or how many cubic feet per minute.★ wind pressure value.Second, on the bearing:Oil bearing (Sleeve Bearing)The traditional DC brushless fan motor design, is the fan rotor (referred to as the rotor) and its axis through the oil bearing, referred to as SLEEVE bearings, pivot fixed in the center of the motor stator, the rotor and the stator to maintain a proper The gap between the shaft and the bearing must also exist between the gap, it will not die deadlock and can not run; and the motor stator structure part (referred to as the stator), after the power in...

How to properly select a fan or blower
How to properly select a fan or blowerAll the design engineers who need to use the cooling fan for the motor and electronics must decide the amount of air required for a particular system to heat up, depending on the power consumption of the system and whether it can take enough heat to prevent System overheating occurs. The fact that the system's useful life will be reduced due to the lack of cooling systems, so the design engineer should also understand that the system's sales and prices may be due to the use of the system does not meet the user's expectations and decline.To select the correct ventilation assembly, the following objectives must be considered:The best air flow efficiencyThe smallest fit sizeThe smallest noiseThe minimum power consumptionMaximum reliability and service lifeReasonable total costThe following steps to choose the cooling fan or fan can help you achieve these goals.The first is to know the total cooling demand, to understand the total cooling demand then h...

The difference between centrifugal fan and axial fan in fan application
The difference between centrifugal fan and axial fan in fan applicationIn fan applications, axial flow and centrifugal are the two most widely used types. We have to understand his similarities and differences in order to according to their own use of the environment, in the fan selection to make the right choice. The following brief on the two types of fan situation.Axial fans are characterized by fluid flow along the fan's axis. Such as fans and fans in the family. The centrifugal type is the fluid from the fan inhalation after the use of centrifugal force to the fluid from the circumferential direction to throw out, such as blowers, range hood.Axial fan: large flow, small pressure head.Centrifugal fan: big pressure, small flow.The flow direction of the axial fan is perpendicular to the direction of rotation of the blade, and the direction of the airflow of the centrifugal fan is cut in the direction of rotation of the blade.What type of fan selection is the most important considerat...
