A cable is sandwiched between a first inner wall surface of a peripheral-wall-side pressing wall portion and a first inner wall surface of a cap-side pressing wall portion, between a second inner wall surface of the peripheral-wall-side pressing wall portion and a second wall surface of the cap-side pressing wall portion, and between a third inner wall surface of the peripheral-wall-side pressing wall portion and a third inner wall surface of the cap-side pressing wall portion to crank the cable to form a cranked portion of the cable. The peripheral-all-side pressing wall portion and the cap-side pressing wall portion sandwich the cranked portion therebetween. Thus, defective soldering may be prevented between a plurality of lead wires and a core-wire soldered portion to which core wires of the lead wires are soldered and connected.

An electric fan is provided, including a labyrinth structure with increased performance of preventing entry of a liquid into a receiving space to receive a stator and a rotor. A clearance is defined between an opposed wall portion of a base and an opposed wall portion of an impeller body, which are opposed to each other in an axial direction of a rotary shaft, to form a labyrinth structure. The opposed wall portion of the base and the opposed wall portions of the impeller body are shaped to form a volume expanding portion within the clearance. The volume expanding portion is constituted from a groove portion for expanding the clearance, having a volume larger than other portions within the clearance.

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.

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.
摘要:
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.
