Abstract
A centrifugal fan includes a housing, a spiral impeller, a suction interrupting member. The housing includes a suction port and a discharge port. The housing further includes an outwardly curved cutoff portion at a side of the discharge port. The spiral impeller is coupled with a motor to suck air through the suction port of the housing in a rotation-axis direction and discharge the sucked air through the discharge port in a direction perpendicular to a rotation-axis. The suction interrupting member prevents air from being sucked into a neighborhood of the cutoff portion through the suction port.
Claims16
A centrifugal fan comprising:
- a housing comprising a suction port, a discharge port and a cutoff portion for dividing an air flow;
- a spiral impeller coupled with a motor to suck air through the suction port of the housing in a rotation-axis direction and discharge the sucked air through the discharge port in a direction perpendicular to a rotation-axis;
- and
- a suction interrupting member preventing air from being sucked into a neighborhood of the cutoff portion through the suction port,
- wherein the housing further comprises an outwardly curved cutoff portion at a side of the discharge port.
A computer cooling fan comprising:
- a housing comprising a suction port, a discharge port and an outwardly curved cutoff portion at a side of the discharge port;
- a spiral impeller coupled with a motor to suck air through the suction port of the housing in a rotation-axis direction and discharge the sucked air through the discharge port in a direction perpendicular to a rotation-axis;
- and
- a suction interrupting member preventing air from being sucked into a neighborhood of the cutoff portion through the suction port.
A fan comprising:
- a housing including at least a suction port and a discharge port, said discharge port including an outwardly curved cutoff portion;
- a spiral impeller for draw air through the suction port in a rotation-axis direction and discharge air through the discharge port in a direction perpendicular to a rotation-axis;
- a motor connected to said spiral impeller for driving said impeller;
- and
- a suction interrupting member preventing air from being sucked into a neighborhood of said cutoff portion through the suction port.
