A, "220V Cooling Fan" near the exit flow is mainly turbulent flow, strong local heat transfer, heating devices should be used for more concentrated, the point must be aligned with the fan outlet mainly concentrated heating element
B, hair will be formed when positive pressure inside the device, the gap can stop dust entering the device
C, the fan will not be affected by the system heat dissipation, low working temperature of the air, the fan longer life
"220V Cooling Fan" ventilation mode
A, uniform air for heating devices is more evenly distributed, the situation is more complex duct
B, flow entering the fan main laminar flow state
C, "220V Cooling Fan" will work under high-temperature air vents, life will be affected
D, a negative pressure within the system, the gap in the dust will enter the cabinet / box
