Abstract: A centrifugal-to-axial mixed flow blower includes a blower enclosure defining a blower chamber and a centrifugal impeller supported on an impeller seat to suspend in the blower chamber. The centrifugal impeller includes a plurality of blades and a radially outward declined flow passage defined between any two adjacent blades and communicable with the blower chamber. The blower chamber is communicable with a rectangular air outlet of a heat dissipation system via a frame passage of a flow guide frame connected to below the blower enclosure. Air stream centrifugally drawn in by the centrifugal impeller passes through the declined flow passages to radially outward and downward flow into the blower chamber and then passes through the frame passage to flow axially through the rectangular air outlet into the heat dissipation system, so as to realize the effects of reduced noise, changing centrifugal vortical flow into axial flow, and decreased flow loss.
