Abstract: A compressor driving device includes: a controller that PWM drives a compressor; an inverter circuit unit that supplies power to an electric motor included in the compressor; a drive circuit that drives the inverter circuit unit according to a control signal; a voltage detector that detects a voltage that is output to the electric motor; and a current detector that detects a current that is output to the electric motor. When a product of a detection value of the voltage detector and a detection value of the current detector is greater than a predetermined comparison value, a duty ratio of the control signal is reduced to cause the input power supplied to the electric motor by the inverter circuit unit to have a predetermined input power level or less.

Abstract: A power unit support structure to minimize vibration of a vehicle body frame. A mount bracket disposed on a vehicle body frame supports a power unit that includes a longitudinal engine. Specifically, the mount bracket is disposed substantially at a center in a vehicle width direction between a pair of right and left center side frames that form part of the vehicle body frame and extend in a vehicle fore-aft direction. The center side frames are connected together with cross members. The mount bracket is mounted to the cross members via a connection member as a vibration damping material. The power unit is then mounted to the mount bracket via a subframe.

Abstract: A condensing unit including a heat exchanger with end plates and a compressor. The heat exchanger is disposed below the compressor so that the end plate takes the load of the compressor. This eliminates the use of a compressor-anchoring base plate, and thus the number of structural parts is reduced. Accordingly, the condensing unit can be further downsized, and cost reduction can be achieved.

Abstract: Radiating member 16 comes into contact with a flat surface of semiconductor device 15 mounted on a circuit board, thereby absorbing heat from device 15. For effective heat-transfer, radiating plate 16 should be made of materials having high thermal conductivity. Housing 18 is formed by molding and fixed with member 16. Housing 18 contains coolant passage 12, and passage 12 contains diaphragm 21. Diaphragm 21 should be made of materials having high thermal conductivity and being easy to work with, and should be processed into a shape that offers highly effective heat-exchange. Coolant passage 12 is partitioned, with diaphragm 21 and housing 18, into a fluid-flow path. A fluid absorbs heat from the semiconductor device while circulating through coolant passage 12; the heated-up fluid is sucked up by a circulating pump then led back to radiator 14 for being refreshed as coolant; and the cooled-down fluid goes out for the next round of the cooling process.
