Problems solved by technology
Among them, the use of centrifugal fans in series requires multiple conversions of the dynamic and static pressure of the wind, resulting in a large loss of wind energy, reducing the wind energy for work, and consuming a lot of extra energy.

The invention discloses a built-in turbo shaft flow motor type strong fan, which comprises a shell provided with an air inlet and an air outlet, and is characterized in that the shell is internally provided with a fixed shaft through a first support element; the fixed shaft is provided with a barrel second support element; two ends of the second support element are in rotary match with the fixed shaft; the end part of the second support element close to the air inlet is provided with a centrifugal impeller; the out wall of the barrel wall of the second support element is provided with a plurality of first vanes which are distributed in a circle; the inner wall of the shell is provided with second vanes axially corresponding to the first vanes; and the inner wall of the shell is provided with third vanes radially corresponding to the centrifugal impeller and axially corresponding to the first vanes. In the invention, the centrifugal type and the axial fans are integrated into a whole, compared with the fan outputting the same wind power, the weight, the volume and the energy consumption of the fan of the invention are reduced greatly, and the fan has large air quantity and high wind pressure, or has higher negative wind pressure and larger vacuum degree.
Description
technical field [0001] The invention belongs to fans, in particular to a vortex axial flow inner motor type powerful fan. Background technique [0002] Existing traditional fans are generally in two forms: centrifugal or axial flow. When high wind pressure (or relatively large negative wind pressure) and large air volume are required during work, and a single fan cannot meet the requirements, multiple fans are often connected in series to meet the above requirements. If so, the volume, weight, and site occupation of the entire system will be relatively large. Wherein the usage of the series connection of the centrifugal blower makes the dynamic and static pressure of the wind need to be converted many times, the wind energy loss is relatively large, the wind energy for doing work is reduced, and a lot of energy is additionally consumed. Contents of the invention [0003] The object of the present invention is to provide a vortex axial flow internal motor type powerful b...
