Patent number: 9052882Abstract: A blower control device changes a PQ characteristic in a second table so that an operating point (QN, PN) on the PQ characteristic in the second table agrees with an operating point (Q0, P0) on a PQ characteristic in a first table. At this time, the blower control device changes the PQ characteristic in the second table at a rate based on QN and Q0. Furthermore, the blower control device changes a load noise characteristic in the second table at a rate based on QN and Q0. Then, the blower control device calculates load noise corresponding to the operating point (Q0, P0) with respect to each rotation frequency ratio from the changed load noise characteristic. And then, the blower control device determines a rotation frequency ratio corresponding to the lowest load noise as a rotation frequency ratio at which a plurality of fans is rotated.Type: GrantFiled: October 30, 2012Date of Patent: June 9, 2015Assignee: FUJITSU LIMITEDInventors: Kazuhiro Nitta, Akira Ueda, Atsushi Yamaguchi, Hiroyuki Furuya, Akihiro Otsuka

Patent number: 8807919Abstract: A counter-rotating axial flow fan with reduced noise at the target operating point achieved without modifying a front impeller, a rear impeller, or a middle stationary portion is provided. An annular rib including a projecting surface for generating turbulent flow is formed on an inner wall portion of a casing at a position off from the middle stationary portion to a side of the rear impeller, the projecting surface extending radially inwardly of the inner wall portion and extending continuously in the circumferential direction of the inner wall portion.
