EXHAUST PORT STRUCTURE OF CENTRIFUGAL FAN

摘要

PURPOSE: An exhaust port structure of a centrifugal fan is provided to produce the centrifugal fan in mass production by forming a V-shaped cut-off part in an exhaust port of a scroll housing. CONSTITUTION: A centrifugal fan(100) includes a motor(101). A pair of motor brackets(102) is coupled to both sides of the motor(101). An impeller(103) is rotatably coupled to an outer portion of each motor bracket(102) in order to suck or exhaust air. A scroll housing(104) is positioned at an outer portion of the impeller(103) so as to guide air. The scroll housing(104) surrounds the impeller(103). One end of the scroll housing(104) is fixed to the motor(101). The scroll housing(104) is formed at an outer wall thereof with a pair of suction ports(105) and an exhaust port(106). A cut-off part(107) is formed at an inner portion of the exhaust port(106) of the scroll housing(104).
