Claims

[Scope of utility model registration request]

A substantially spindle-shaped cylindrical casing with openings at both ends as a suction port and a discharge port, and a cylindrical boss portion of a taber profile that is fixed radially toward the rear of the large diameter part within this cylindrical casing, and whose base side is open at both ends. The rotary shaft is fixed to the center of the boss part by a plurality of connected stator vanes and a nearly disk-shaped mounting plate attached like a lid to the front opening end of the boss part of the stator vanes. a motor; a hemispherical spinner; the outer surface of the spinner has blades that extend radially toward the center; the rear end of the spinner faces the front end of the boss portion of the stationary blade with a slight gap; the blade is attached to the rotating shaft of the motor; The mounting plate has a mounting hole in the center into which the motor is fitted, and around the mounting hole there is air flowing from the gap between the rear end of the spinner and the front end of the boss portion of the stationary blade. A mixed flow type duct fan, characterized in that it has a configuration including a ventilation section that partially contacts the surface of the outer shell of the motor and is used for cooling the motor.
