Tiny Cooling Fan was such a ’blow’ the

When the energy of "Tiny Cooling Fan" impeller rotation, the gas from the inlet into the impeller axially, pushed by the impeller blades increases the gas leaving, then flows into the guide vanes. The stream becomes the vanes deflect the axial flow, while the gas is introduced into the diffuse tube, and further converts the gas kinetic energy to pressure, and finally the introduction of the work lines.
Work quality "Tiny Cooling Fan" blades similar to airplane wings. However, the role of the latter is to lift up on the wing and support the weight of the aircraft, and high-quality axial fans and air movement is a fixed position.
Quality "Tiny Cooling Fan" cross-section is generally airfoil. Position of the blade can be fixed to be rotating around its longitudinal axis. Blade or blade pitch angle can not be adjusted with the flow or adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. Small blade pitch angle to produce a low flow rate, the spacing can be increased to produce a higher flow rate.
