Patent number: 9745990Abstract: A fan frame includes a first frame and a second frame. The first frame includes at least a first sidewall and a first connecting element, wherein the first connecting element is disposed on the first sidewall. The second frame includes at least a second sidewall and a second connecting element, wherein the second connecting element is disposed on the second sidewall and at least partially overlapped with the first connecting element. The second connecting element includes a first end and a second end in a first direction, wherein the first end and the second end are bent toward the first connecting element, respectively, for grasping the first connecting element. As a result, the accuracy error and the precision error are avoided, the stresses are internally counterbalanced, and the deformation of the fan frame is avoided.Type: GrantFiled: August 8, 2014Date of Patent: August 29, 2017Assignee: DELTA ELECTRONICS, INC.Inventors: Chao-Wen Lu, Chun-Chih Wang, Ding-Wei Chiu

Patent number: 9635781Abstract: A heat dissipating device for dissipating the heat produced by a heating element is disclosed. The heat dissipating device includes a fixing assembly, two moving assemblies and an elastic assembly. The fixing assembly has a thermal conductive member. Each moving assembly has a mass body and is relatively moveable with respect to the fixing assembly. The two moving assemblies are disposed on two opposite sides of the fixing assembly, respectively, and each moving assembly forms a moving space with respect to the fixing assembly. The elastic assembly connects the fixing assembly to the two moving assemblies.Type: GrantFiled: August 19, 2014Date of Patent: April 25, 2017Assignee: DELTA ELECTRONICS, INC.Inventors: Chao-Wen Lu, Chun-Chih Wang, Ding-Wei Chiu

Patent number: 9568019Abstract: A fan device includes a bottom shell, a cover, and an impeller. The cover includes a main body, a support, and a spoiler. The main body has a through opening. A connection position between the support and the main body has a first folding line. The support is bended along the first folding line to form a portion of the through opening. The support is perpendicular to the main body, and is abutted against the bottom shell. A connection position between the spoiler and the main body has a second folding line. The spoiler is bended along the second folding line to locate in the through opening. An acute angle is formed between the spoiler and the surface of the main body facing away from the bottom shell. The impeller is located in an accommodating space between the cover and the bottom shell.Type: GrantFiled: December 17, 2014Date of Patent: February 14, 2017Assignee: DELTA ELECTRONICS, INC.Inventors: Chao-Wen Lu, Chun-Chih Wang, Ding-Wei Chiu

Patent number: 9284985Abstract: An oil seal bearing of a fan includes a ring-shaped body for supporting a shaft of the fan, and a protruded portion disposed on the ring-shaped body. The protruded portion has a first slope, wherein the first slope is disposed corresponding to an inner top surface of a hub of the fan. An oil storage space is formed between the first slope, the shaft and the inner top surface for storing a lubricant. A first angle is formed by the extension of the first slope and the inner top surface, such that the lubricant is retained by the capillarity between the first slope and the inner top surface. Under this circumstance, the oil sealing is achieved without any additional oil seal, the effective bearing height is maximized, and the advantages of enhancing the supporting efficiency and lengthening the lifetime of the product are also achieved.Type: GrantFiled: August 8, 2014Date of Patent: March 15, 2016Assignee: DELTA ELECTRONICS, INC.Inventors: Chao-Wen Lu, Chun-Chih Wang, Ding-Wei Chiu
