    摘要: An electronic component cooling apparatus capable of permitting a sufficient amount of air to be fed to an electronic component to be cooled. An impeller which includes a plurality of blades for sucking air from one side in an axial direction of a revolving shaft of a motor is fixed on a rotor of the motor. A casing having a cylindrical cavity defined therein in which the motor and impeller are received is constructed of a peripheral wall arranged so as to surround the impeller and a closing wall for closing an end of the cavity on the other side in the axial direction. The peripheral wall is formed at a portion thereof in proximity to an end thereof on the one side with a lateral discharge port through which air suckedly introduced into the cavity is discharged so that a surrounding portion for surrounding a whole circumference of the impeller is left at a portion of the peripheral wall in proximity to an end on the other side. The casing is provided with a spacer means for providing an interval between the casing and an opposite member.

    摘要: A heat sink for an electronic component cooling apparatus being small in size and having reduced weight, being capable of coping with increasing amounts of heat generation from the electronic component and capable of performing high cooling efficiency. A plurality of radiation fins 3 surrounding an impeller of a fan are mounted on a side of a base 2 of a heat sink 1. A heat conductive thick portion comprising linear ribs 4 and an annular rib 5 is formed on the base 2 where it is surrounded by the radiation fins 3. The linear ribs 4 and the annular rib 5, having more thickness than the radiation fin mounting area 6, are formed of a pattern that can reduce the resistance of heat transfer between a heat source opposed-portion 7, which opposes to the heat source of the electronic component and the radiation fin mounting area 6.

    摘要: A heat sink preform having a base 2, a fan case engagement portion 3 and a radiating fin formation portion is integrally formed by extrusion molding. A plurality of radiating fins 5 having a tong ratio which is defined as a ration of the height of the radiating fins with respect to the interval dimension between neighboring radiating fins of more than or equal to 10 is formed by subjecting the radiating fin formation portion to cutting work. In this way, a cooling fan attached type heat sink with a plurality of radiating fins having a shape that is difficult to be formed or cannot be formed or having a large tong ratio can be produced with low costs and with relative ease.

The fan unit mounting frame includes a pair of mounting legs provided thereon with hooks, which are engaged with hook engagements provided on a base of the heat sink. A top plate of the fan unit mounting frame is provided thereon with projections acting as a first pivotal movement preventing engagement structure and fitted in gaps defined between adjacent radiation fins of a radiation fin unit. Also, the top plate is provided thereon with projections which are abutted against end surfaces of the radiation fins positioned in a second direction, to thereby act as a second pivotal movement preventing engagement structure for preventing pivotal movement of the top plate in the second direction.
