Abstract: PROBLEM TO BE SOLVED: To provide an air-cooled rotating electric machine having improved cooling performance.SOLUTION: A rotating electric machine 1 includes a case 70, a stator 80, a rotor 10 and plate portions 85. The rotor 10 includes projecting portions 19 projecting to sides of a front side bottom portion 72 and a rear side bottom portion 73 relative to end portions in the axial direction and extending from the radial inner side to the outer side. The plate portions 85 are located between the rotor 10 and the front side bottom portion 72 and the rear side bottom portion 73, and have central holes 851 each positioned at the center and having an inner diameter smaller than an outer diameter of the rotor 10 to divide a flow of cooling gas on the sides of the front side bottom portion 72 and the rear side bottom portion 73 and a flow of cooling gas on the rotor 10 side. Therefore, when the rotor 10 rotates together with a shaft 90, the cooling gas is circulated in a space between the rotor 10 and the front side bottom portion 72 and the rear side bottom portion 73, due to rotation of the projecting portions 19.

Abstract: PROBLEM TO BE SOLVED: To provide a starter generator with which consumption power can be reduced.SOLUTION: A power generator comprises: a rotary electric machine 10 and a compressor 20. The compressor 20, including a common shaft 80 with the rotary electric machine 10, is capable of varying compression capacity of cooling medium in forward rotation and reverse rotation of the shaft 80. A mechanical clutch 50 conducts power transmission between an inside rotary portion 42 of a pulley 40 rotating in an interlocking manner with an engine 2 and an outer rotary portion 83 rotating in an interlocking manner with the shaft 80 of the rotary electric machine 10. A centrifugal clutch 51 transmits power from the inside rotary portion 42 to the outer rotary portion 83 when a rotation number of the engine 2 becomes more than a prescribed value. A one-way clutch 61 transmits power from the outside rotary portion 83 to the inside rotary portion 42 when the rotary electric machine 10 rotates the shaft 80 in forward rotation. Consequently, the starter generator can reduce consumption power comparing to a vehicle driving device using a conventional electromagnetic clutch.

Abstract: PROBLEM TO BE SOLVED: To provide a collision jet type cooler having good cooling efficiency.SOLUTION: A cooler 2 includes: a base plate 3; a partition plate 5; and a coolant nozzle 6. The base plate 3 is attached with a cooling object on its front surface 3a, and attached with a fin 4 on a back surface 3b. The partition plate 5 divides an in-housing space into a space facing the base plate 3 and a space separated from the base plate 3. The former space configures a coolant discharging path 14, and the latter space configures a coolant supplying path 12. The coolant nozzle 6 extends from the partition plate 5 toward the base plate 3, has a long opening in a coolant flowing direction, and jets coolant toward the base plate 3. A channel cross sectional area of the coolant supplying path 12 is continuously and gradually decreased from an upstream side toward a downstream side of a flow of the coolant, or a channel cross sectional area of the coolant discharging path 14 is continuously and gradually increased from the upstream side toward the downstream side of the flow of the coolant. A rate of gradually decreasing or the rate of gradually increasing is nonlinear.

Abstract: PROBLEM TO BE SOLVED: To provide technology for securing a coolant flow rate suitable for required cooling performance.SOLUTION: In a semiconductor lamination unit, a center axis J1 of a supply tube 7 is decentered further away from the center of a cooling plate 2a in the longitudinal direction thereof than a center axis J3 of a connection tube 5, and an inside fringe 7a of the supply tube 7 is positioned further away from the center of the cooling plate 2a in the longitudinal direction thereof than an inside fringe 5a of the connection tube 5. Coolant is made to flow more in a further remote place than the inside fringe 5a of the connection tube 5 right after it enters from the supply tube 7, and a coolant flow rate entering a lateral passage 15a of the cooling plate 2a is thereby decreased by decreasing the coolant hitting the inside fringe 5a. Also, a coolant flow rate flowing toward downstream cooling plates 2b-2j through a vertical passage 15b of the connection tube 5 is increased. Thereby, compared with the cooling plate 2a in which an abutting region of a semiconductor package 3 is present only on one side, the coolant flows more to the cooling plates 2b-2j in which the abutting region of the semiconductor package 3 is present on both sides.
