Title:
DUCT FAN
Document Type and Number:
WIPO Patent Application WO/2018/223748
Kind Code:
A1
Abstract:
Disclosed is a duct fan, comprising: a duct (1) having a central axis, an air inlet and an air outlet being respectively located at an upper end and a lower end of the duct (1); a propeller hub shaft arranged on the central axis of the duct (1); a plurality of rotor blades (2) which are arranged on the propeller hub shaft, close to the air inlet and capable of rotating along with the propeller hub shaft; a fixing sleeve, the propeller hub shaft being mounted in the fixing sleeve; a plurality of stationary blades (3), two opposite ends of each stationary blade being respectively connected to the fixing sleeve and an inner wall of the duct (1), and each stationary blade (3) being provided with a heat dissipation structure; and a power-driven device (4) arranged in the fixing sleeve and located below the plurality of rotor blades (2), wherein the power-driven device (4) is connected to the propeller hub shaft so as to drive the propeller hub shaft to rotate, and the power-driven device (4) is connected to the heat dissipation structure so as to dissipate heat by means of the heat dissipation structure. Arranging the heat dissipation structure at each stationary blade (3) of the duct fan or integrally forming the heat dissipation structure and each stationary blade (3) enables the stationary blades (3) to have the function of balancing the reaction torque while having the function of heat dissipation, thereby significantly improving the heat dissipation effect and also saving on space.
