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： An electronic component cooling apparatus capable of minimizing a reduction in cooling efficiency even when discharge of air heated is restricted to two directions and reducing a manufacturing cost. The cooling apparatus includes a heat sink including an elongated base having a plurality of radiation fins arranged thereon, as well as a fan unit. The fan unit includes a casing in which an impeller provided with a plurality of blades and a motor for revolving the impeller are received. The casing is releasably mounted on the heat sink. The heat sink and the casing of the fan unit cooperate with each other to define two discharge ports and form an air flow space which continuously extends between an end of the radiation fins facing the casing and an opposite wall of the casing.

摘要： A heating element cooling apparatus which is capable of improving the cooling efficiency without greatly increasing the overall weight thereof. A heat sink 2 for the heating element cooling apparatus is equipped with an air fan 1. A heat conducting element 3 having higher heat conductivity than a base 2a of the heat sink 2 is conductivity attached to the base 2a. Plural radiation fins 6 are mounted on an extended portion 3c of the heat conducting element 3 which extends exceeding the base 2a. The heat generated by a heating element 4, which is heat-conductively attached on the heat conducting element 3, is outwardly conducted toward the peripheral portion of the heat sink through the heat conducting element 3 and radiated from the radiation fins 2b, resulting in increasing the radiation efficiency.

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.

摘要： The present invention provides an axial-flow fan capable of entirely cooling an object to be cooled even when the distance between the object to be cooled and an air discharge opening of the axial-flow fan is short. A plurality of stationary blades 11A to 11E are disposed at intervals in a rotating direction of a rotor and located inside an air discharge opening 16 of an air channel 19. Each of the plurality of stationary blades 11A to 11E has an external end portion 11a connected to an inner wall portion of a fan housing 3, an internal end portion 11b connected to a peripheral wall portion 11B of a motor case 10, a discharge-side edge portion 11c formed between the external end portion 11a and the internal end portion 11b and located at a side of the air discharge opening 16, and a suction-side edge portion 11d formed between the external end portion 11a and the internal end portion 11b and located at a side of the air suction opening 14. An outer surface of the bottom wall portion 10A of the motor case 10 is located closer to a side of the air suction opening 14 than the discharge-side edges 11c of the plurality of stationary blades 11A to 11D are located.
