Patent number: 8057167Abstract: The present invention provides a fan motor capable of achieving both an improvement in a self cooling function of the fan motor and a reduction in fan noise, and of preventing the occurrence of heat damage, problems, and the like caused by external radiation heat and by self-heating, fan noise, and deterioration in fan performance and in fan efficiency. The fan motor (1) includes: a shroud (2); a motor (3) secured to and supported at the shroud (2); an axial-flow fan (4) connected to a rotation shaft part of the motor (3); and a heat shield panel (5) mounted at the rear side of the motor (3) with a gap being provided therebetween, in which the heat shield panel (5) has a spatula-shaped air guiding part (52) projecting outward in a radial direction at least one location on an outer circumference portion; and the air guiding part (52) has a width gradually reducing toward an outer side and a fan-rotational-direction leading edge part (53) having an arc shape.Type: GrantFiled: September 17, 2008Date of Patent: November 15, 2011Assignee: Mitsubishi Heavy Indusries, Ltd.Inventors: Atsushi Suzuki, Takayuki Kobayashi, Kazuyuki Kamiya, Yuuko Enya, Takahisa Hirano

Patent number: 7559744Abstract: There is provided a propeller fan in which a clearance between a rotary vane wheel and a shroud is constant three-dimensionally to improve air blowing efficiency and suppress noise. Furthermore, there is provided a propeller fan in which a span length of the rotary vane wheel with respect to the shroud is varied between a front edge portion and a rear edge portion to improve air blowing efficiency and suppress noise. Still further, there is provided a propeller fan characterized in that chamfering is applied only to a negative pressure face of a circumferential outer edge portion of a vane.Type: GrantFiled: March 2, 2006Date of Patent: July 14, 2009Assignee: Mitsubishi Heavy Industries Ltd.Inventors: Atsushi Suzuki, Tetsuo Tominaga, Tsuyoshi Eguchi, Kazuyuki Kamiya, Asuka Soya
