Patent number: 7209355Abstract: A cooling device for cooling a heat-generating component includes a circulating passage arranged to have coolant circulate therein, a centrifugal pump including a first case made of metallic material, a second case made of resin material, and an impeller accommodated in the pump chamber, and a radiator provided at the circulating passage and being operable to release heat from the coolant. The first case has a surface arranged to contact the heat-generating component. The second case forms a pump chamber between the first case and the second case. The pump chamber stores the coolant therein. The impeller includes open-type vanes arranged to pressurize the coolant as to have the coolant flow through the circulating passage. The cooling device has a high cooling efficiency as well as a high operating efficiency of the motor while having a simple construction and a small overall size and a small thickness.Type: GrantFiled: October 29, 2004Date of Patent: April 24, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shinya Koga, Toshihiko Matsuda, Kyo Niwatsukino, Toshisuke Sakai, Toshiyuki Kubota, Masashi Hirose, Shigeru Narakino, Yoshimitsu Aizono, Kazuyuki Kasahara

Patent number: 6856054Abstract: A brushless DC motor includes a substrate fixed to the center of a stator core. The substrate includes a central substrate portion and an arm substrate portion extending from the central substrate to a salient pole. The arm substrate is accommodated between coils. A driver IC is mounted on the central substrate portion, and a magnetic pole position sensor is mounted on the arm substrate portion. This structure provides a thin brushless DC motor which assures good motor performance and stable noise and vibration levels, improves motor efficiency, and reduces the number of components and assembling steps.Type: GrantFiled: September 23, 2002Date of Patent: February 15, 2005Assignee: Matsushita Electric Industrial Co., LtdInventors: Yoichi Shukuri, Kyo Niwatsukino, Yoshimitsu Aizono

Patent number: 6808371Abstract: An ultra-thin pump of the present invention includes a ring-shaped impeller including many vanes arranged along its outer region and a rotor magnet at its inner region, a motor stator provided in a space encircled by an inner peripheral surface of the rotor magnet of the impeller, and a pump casing that includes a suction port, a discharge port and a cylinder disposed between the motor stator and the rotor magnet and houses the impeller. The impeller is rotatably supported by the cylinder. A cooling system of the present invention includes a cooling device for cooling a heat-producing device by heat exchange using coolant, a radiator for removing heat from the coolant, and the ultra-thin pump for circulating the coolant. The ultra-thin pump is simple in structure, operates efficiently and can be manufactured at low cost, and the cooling system is thin in structure and performs efficient cooling.Type: GrantFiled: September 23, 2002Date of Patent: October 26, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kyo Niwatsukino, Yoichi Shukuri, Yoshimitsu Aizono, Shigeru Narakino

Patent number: 6795312Abstract: A circulation path, a radiator and a reserve tank which can remove air bubbles from the fluid passageway, constitute parts of a closed circulation path, and are formed by joining a flow path wall-forming radiation board on which curved surfaces as flow path walls are formed, with a flat plate-like flow path wall-forming radiation board as another curved surface by welding or the like. Therefore, the efficiency of heat exchange of a cooling apparatus for electronic equipment can be improved, removal of air bubbles from the flow passageway and reduction in size, weight and thickness is made possible without causing air lock.Type: GrantFiled: October 4, 2002Date of Patent: September 21, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shigeru Narakino, Kyo Niwatsukino, Kazuyuki Kasahara, Masashi Hirose, Yoshimitsu Aizono
