Patent number: 11473586Abstract: A thin cooling fan includes a fan shell, a motor, a plurality of blades, and a PCB. The fan shell comprises a base plate and a shell cover which cover to each other to form an inner space. The base plate has a first surface facing toward the inner space and a second surface having a receiving space and opposite to the first surface. The motor is combined in the inner space. The blades are disposed in the inner space and rotated by the motor. The PCB is disposed in the receiving space and flush with the second surface. Thus, the whole thickness of the cooling fan is reduced and the flow channel design in the inner space is not affected.Type: GrantFiled: October 10, 2019Date of Patent: October 18, 2022Assignee: DELTA ELECTRONICS, INC.Inventors: Cheng-Wei Chen, Hsiang-Jung Huang

Publication number: 20160146216Abstract: A centrifugal fan includes a fan frame, an impeller and a motor. The fan frame includes a base plate, a sidewall and a plurality of air deflectors. The sidewall and the air deflectors are disposed on the base plate. The base plate, the sidewall and the air deflectors form an accommodating space and an air outlet. The impeller is disposed in the accommodating space. There is a flow channel between the impeller and the sidewall. The motor is connected with the impeller and drives the impeller to rotate. The air deflectors are set separately along the extension direction of the flow channel and toward to the air outlet. The distance between the air deflector which is closer to the air outlet and the impeller is larger.Type: ApplicationFiled: June 9, 2015Publication date: May 26, 2016Inventors: Ya-Ting CHANG, Hsiang-Jung HUANG

Patent number: 9322413Abstract: Disclosed herein is a centrifugal fan. A driving device is connected to an impeller and drives the impeller to rotate within a case. The flowing channel includes a pressure-enhanced section and an output section. The case includes an air input section, an axial inlet section and a radial air outlet. The bottom base has a center and allows the driving device to be secured thereon. Multiple ribs are interconnected between the bottom base and the case to define air inlets among the ribs, the bottom base and the case. The air inlet within the output section has an outmost edge, which is farther from the center than an outmost edge of the air inlet within the pressure-enhanced section, or the air inlet within the output section has an area, which is larger than that of the air inlet within the pressure-enhanced section.Type: GrantFiled: October 28, 2011Date of Patent: April 26, 2016Assignee: DELTA ELECTRONICS, INC.Inventors: Hsin-Chen Lin, Hsiang-Jung Huang
