摘要： The present invention provides a mounting structure of a rotary shaft of rotary electric machinery in which it is possible to cope with vibration of the rotary shaft in an axial direction with a low parts count. A fitting groove into which a portion of a rear side stopper is fitted is formed at a rear end portion of the rotary shaft. A rear side stopper has three projecting chips fitted into the fitting groove and three leaf spring chips in contact with an inner ring of a rolling bearing forming a bearing structure. The rear side stopper has a structure in which the rear side stopper generates spring force for restoring an original shape thereof when the rear side stopper is compressed in an axial direction of the rotary shaft. The rear side stopper is disposed in a compressed state between a wall face surrounding the fitting groove and the inner ring of the rolling bearing.

摘要： Four tapered portions are formed on an end portion of an inner wall surface of an air channel at four locations corresponding to four corners of the profile of a surface of a housing where a suction port is formed. The four tapered portions are each inclined outwardly in a radial direction of a rotary shaft from a discharge port side toward the suction port side and extending in a rotational direction of an impeller. The tapered portions each include a main portion which is shaped such that an angle formed between the main portion and an axis of the rotary shaft gradually becomes smaller from one end of the main portion located rearward as viewed in the rotational direction of the impeller toward the other end of the main portion located forward as viewed in the rotational direction of the impeller.

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.

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： The present invention provides a component cooling apparatus in which it is possible to suppress resonation of a fan housing due to the rotation of the fan. Four extended portions 33A, 33B extending into an air suction opening 25a are integrally formed with the duct 5. Projected portions 35A, 35B projecting toward the fan 3are integrally formed with the extended portions 33A, 33B respectively. The end portions of the projected portions 35A, 35B are arranged in contact with end portions of corner portions which are located around the housing-side mount holes 21a of the flange portion 21. The fan 3 is fixed inside the duct 5 by inserting a mounting member such as a screw and a bolt into each pair of a housing-side mount hole 21a and a duct-side mount hole 33a with four housing-side mount hole 21a and four duct-side mount hole 33a being aligned with each other. Accordingly, the fan housing 11 and the duct 5 are not in contact with each other except at mounting portions around the housing-side mount holes 21a. The mounting portion of the fan housing 11 and the mounted portion of the duct 5 are in contact with each other only at peripheries of opposing openings of each pair of the housing-side mount hole 21a and the duct-side mount hole 33a that have been aligned.
