<P>PROBLEM TO BE SOLVED: To reduce cost and weight by integrating a cooling pump for cooling an inverter and a motor with an air-conditioning electric compressor, to dispense with a motor used only for driving the cooling pump. <P>SOLUTION: The cooling pump 500 for cooling the inverter 300 is installed in the air-conditioning electric compressor 400, and the cooling pump 500 is driven using the rotation of a rotating shaft 420 of a motor 410 of the electric compressor 400. Cooling oil flowing in the cooling pump 500 is thereby cooled using air-conditioning gas flowing in the electric compressor 400. <P>COPYRIGHT: (C)2009,JPO&INPIT |
