Abstract

Disclosed are a fan and a wind pressure enhancement method thereof, wherein the fan has an impeller having a plurality of blades and an end portion of each blade is commonly connected with an outer collar that is coaxial with respect to the fan blades, a convergent wind channel being delimited by the fan blade and the outer collar such that, during the operation of the fan, an air flow generated by the fan blade flows through the convergent wind channel to become a strong wind of high pressure and high speed, and the convergent wind channel can compress the air flow generated by the fan blade to make the air flow become a strong wind of high pressure and high speed. As such, the impeller can achieve good performance with less blades. Besides, the convergent wind channel can also reduce the air flow loss at the end portion of the blade.
