  • Patent number: 7170746
    Abstract: A heat-emitting element cooling apparatus that can improve a cooling effect on a heat-emitting element without increasing its size is provided. A heat sink is so constructed that all or part of radiation fins are located outside the contour of a base as seen from a side on which an axial flow fan unit is mounted. Then, the axial flow fan unit is so constructed as to discharge air along the portions of the radiation fin located outside the contour of the base.

  • Publication number: 20050253467
    Abstract: There is provided a fan unit in which when the fan unit is conveyed, existence of a plurality of lead wires will not become an obstacle to the conveyance. Four lead wire engaging sections 27, 29, 31, and 33 are provided along the contour of an outer wall section 25 of a fan casing 15 as the fan casing 15 is viewed from a predetermined position in a forward direction. Then, the lead wire engaging sections 27, 29, 31 and 33 are configured to engage a part of lead wires 24 so as to prevent the lead wires 24 from coming out of the fan casing 15 one or more during the conveyance.

  • Publication number: 20040261976
    Abstract: An axial-flow fan unit that produces less noise is provided. Blades 19 are exposed from a venturi 29. The shape of each of the blades 19 is so defined that a space formed between at least an inner surface 28a of each of web leg sections 28A to 28C and an edge 19a of each of the blades 19 located in the radially outward direction of the blades 19 expands toward the ends of the web leg sections 28A to 28C (or web bodies 30A to 30C). With this arrangement, noise produced when the blades 19 rotate along the web leg sections 28A to 28C is reduced.

  • Patent number: 6621699
    Abstract: An electronic component cooling apparatus is provided that can prevent a reduction in a heat dissipation effect on an electronic component with a pushing force toward a heat sink thereof being applied to the opposite wall of a casing thereof. Pushing force transferring sections 37 for transferring a pushing force from mounting tools 35 to a heat sink 3 through contact with leading ends of radiation fins 11 are integrally formed on a pair of wall sections 25a of a casing 21. The pushing force transfer sections 37 have a shape that can distribute the pushing force and transfer distributed force to the heat sink 3 so as to prevent a force applied to an electronic component MPU by the pushing force from being locally and extremely increased.

  • Patent number: 6619385
    Abstract: The present invention provides a cooling apparatus which can increase air flow. A plurality of blades 25 are provided with extending portions 25b of the blades which extend outwardly in the direction of the diameter of the axis 9a of the motor 9 and rotate at such a space that is outside and surrounds the opening 13 in the space 17. The extending portions 25b of the blades are integrally formed with the blades 25. The rim portions 25c of the extending portions 25b of the blades which are disposed on the side of the first wall part and extend along the first wall part are sloped so as to be gradually away from the first wall part 15 as they extend toward the edges.

  • Patent number: 6419007
    Abstract: A heat sink-equipped cooling apparatus capable of exhibiting increased cooling performance and durability and being reduced in dimensions in a radial direction thereof. A heat sink includes a radiation fin unit including a plurality of radiation fins arranged so as to surround a virtual central line while keeping a center thereof aligned with the central line. A cooling fan includes an impeller including a plurality of blades and rotated through a motor. The cooling fan is mounted on the heat sink in such a manner that the impeller is positioned above the radiation fin unit of the heat sink. The radiation fins each are inclined with respect to a virtual vertical plane so as to form a predetermined inclination angle &thgr; therebetween. The inner edges of the radiation fins are connected in a manner to be heat-transferable or in a manner that a thermally conductive passage is formed between the inner edges.

  • Patent number: 6375418
    Abstract: A heat sink-equipped cooling apparatus capable of increasing a size of an air discharge port as compared with a prior art. A fan unit is mounted on a heat sink. The heat sink includes a base formed into a contour having first and second sides defined so that an angle therebetween is substantially 90 degrees. A side wall of the base and a casing of the fan unit cooperate with each other to provide an air discharge port at a position corresponding to sides of the base opposite to the first and second sides while being combined with each other. The air discharge port is constructed so as to permit air sucked through an opening to be discharged therethrough.

  • Patent number: 6311767
    Abstract: A computer fan assembly is described which may be constructed so as to be suitable for use in enclosures for notebook computers or laptops. A heat pipe may be secured to a housing of the computer fan assembly. The heat pipe may be located in a position so that heat is transferred away from the heat pipe by air passing through the housing. Heat may, for example, be conducted from the heat pipe and then convected by means of fins to the air passing through the housing.
