Use Cooling Fan Manufacturer achieve cooling effect

Centrifugal "Cooling Fan Manufacturer" work, the blade pushing air in a direction perpendicular to the axis (i.e., radial) flow, the intake air is in the axial direction, while the outlet was perpendicular to the axial direction. In most cases, the use of an axial fan cooling effect can be achieved, however, and sometimes if you need to be rotated 90 degrees exhaust airflow or need a larger pressure, we must use centrifugal "Cooling Fan Manufacturer". Fan strictly speaking, also belong to the centrifugal fan. Francis fan, also known as the diagonal flow fan, first glance, Francis fan and axial flow fan is no different, in fact, Francis fan intake is along the axis, but the outlet is a diagonal direction along the axis and vertical axis. This "Cooling Fan Manufacturer" due to the blades and housing, said conical, thus resulting in a high pressure, in the same size and other comparable performance under, compared with axial fans, centrifugal fan noise lower.
