20090015185 | Semiconductor Module, and Hybrid Vehicle Drive Device Including the Same - A bus bar constitutes a power line and another bus bar constitutes an earth line. The bus bars are layered in the normal direction of an insulating substrate via an insulating member. Here, the bus bar positioned at the upper side is formed by a metal member and the bus bar positioned at the lower side is formed by a wiring layer formed on the insulating substrate. Since one of the bus bars is the wiring layer fixed to the insulating substrate, it is possible to assure heat radiation of the bus bar. Thus, it is possible to make the bus bar a wiring layer having a comparatively small cross sectional area and reduce the semiconductor module size in the normal direction. By mounting the semiconductor module on the drive device for a hybrid vehicle, it is possible to reduce the vertical-direction size when mounted on the vehicle and lower the position of the center of gravity of the vehicle to improve the running stability. | 01-15-2009 |
20090090490 | COOLER - A cooler includes a substrate for disposing a semiconductor device thereon, a plate member fixed to a back surface of the substrate, a primary pipe, and a secondary pipe. A space sandwiched between the substrate and the primary pipe defines a first flow path for a coolant. The primary pipe and the secondary pipe configure a second flow path for a coolant. The secondary pipe is positioned to jet a coolant toward a region opposite to that having the semiconductor device disposed therein. The second flow path is separated from the first flow path. | 04-09-2009 |
20090145586 | COOLER - A cooler is provided with a thermal transmission member having a surface to be sprayed with a cooling fluid. The heat transmission member includes a first groove formed on the surface, and a second groove intersecting with the first groove and being formed on the surface. | 06-11-2009 |
20090205802 | COOLING DEVICE AND VEHICLE PROVIDED WITH THE SAME - The present invention is a cooling device including a heat absorbing unit, provided with an inflow port of a coolant medium and a discharge port for discharging the coolant medium, sealing the coolant medium in parts other than the inflow port and the discharge port, wherein the heat absorbing unit includes an upper member having an installation surface where semiconductor elements serving as an object to be cooled are installed and a cooling surface serving as a back surface of installation surface, and a lower member forming a chamber having cooling surface as a part of an inner wall surface together with upper member. Injection ports communicating with inflow port for injecting the coolant medium toward cooling surface are provided and the discharge port is provided at a position lower than opening positions of injection ports in lower member. Thereby, it is possible to provide a cooling device of improving cooling efficiency and reducing cooling unevenness. | 08-20-2009 |
20090250195 | HEAT SINK AND COOLER - A heat sink includes a plurality of fins. The fins are formed to serve as partition walls of flow paths of a coolant. The fins are formed such that the coolant flows along a surface thereof. A merge space is formed to allow the coolant in the flow paths separated by the fins to merge. The merge space is formed in the flow paths formed by the fins. | 10-08-2009 |

20090250272 | VEHICLE DRIVE MECHANISM - A vehicle drive mechanism includes a power transmission mechanism which has a rotary electric motor and a gear mechanism for transmitting mechanical power from the rotary electric motor to a drive shaft disposed coaxially with an output shaft of the rotary electric motor, and a control unit formed of a plurality of elements and controlling an operation of the rotary electric motor. At least one of the elements which constitute the control unit is disposed on a periphery of at least one of the rotary electric motor, the drive shaft, and the gear mechanism. | 10-08-2009 |
20090250275 | DRIVE DEVICE FOR HYBRID VEHICLE - A casing for integrally accommodating a motor generator and an inverter includes an accommodating portion forming an inverter accommodating space, and an accommodating portion forming a motor accommodating space. The casing has a structure wherein the accommodating portions are integrally formed. Thereby, a drive device for a hybrid vehicle having the inverter and the motor generator accommodated in an integrated fashion prevents external leakage of electromagnetic noises of the inverter from the drive device. | 10-08-2009 |
20100084206 | VEHICLE DRIVE SYSTEM - A vehicle drive system includes a battery, motor generators driving the vehicle using electric power from the battery or driven by the vehicle, a PCU integrated with the motor generators, having inverters and controlling the motor generator, cooling water cooling inverters, and oil cooling motor generators. The PCU includes a smoothing capacitor and a filter capacitor provided electrically closer to the battery than the smoothing capacitor. Here, the smoothing capacitor is cooled by the cooing water, while the filter capacitor is cooled by the oil. | 04-08-2010 |
20110291282 | JUNCTION BODY, SEMICONDUCTOR MODULE, AND MANUFACTURING METHOD FOR JUNCTION BODY - A junction body has a first member and a second member each of which is provided with a joining surface whose main component is copper. A solder member containing, in a tin-base solder material, a three-dimensional web structure whose main component is copper is provided between the first member and the second member. A copper-tin alloy whose average thickness is 2 μm or more but 20 μm or less is provided between the joining surfaces and the three-dimensional web structure. | 12-01-2011 |
