In the first packaging arrangement, major capacitor axes of each one of the capacitor units are co-linear with one another and minor capacitor axes of each one of the capacitor units are oriented parallel but not co-linear with one another. Assembling the power converter further includes arranging a plurality of IGBT modules of a transistor subassembly for power switching in the power converter in a second packaging arrangement. In the second packaging arrangement major module axes of each one of the IGBT modules are oriented parallel but not co-linear with one another and minor module axes of each one of the IGBT modules are co-linear with one another.Type: GrantFiled: April 1, 2009Date of Patent: January 11, 2011Assignee: Caterpillar IncInventors: Jon Husser, Keith E. Dixler, Thomas M. Baker, Robert R. Sychra

Patent number: 7869209Abstract: This rack (1) houses rackable electronic gear modules (2, 3) and has cooling by natural convection thanks to ventilation orifices (20, 21) provided in its bottom (10) and top (11) walls and forced air cooling thanks to internal air distribution ramps (30) fed with air under pressure through the intermediary of a distribution box (31) connected to a forced air circulation duct (37). The use of internal distribution ramps for the forced air makes it possible to produce a pulsed air circulation providing only a slight obstacle to the air circulation obtained by natural convection. Compared to usual configurations, this makes it possible to lower the operating temperature reached by the equipment in the event of loss of the forced ventilation.Type: GrantFiled: August 27, 2007Date of Patent: January 11, 2011Assignee: ThalesInventors: Gerard Nemoz, Bruno Bellin

Patent number: 7859837Abstract: The invention relates to an electronic device operating in difficult environments. The electronic device comprises at least one printed circuit board supporting heat-dissipating electronic components, a heat sink, a first side of which is in contact with electronic components on a first side of the printed circuit board, and a second side of which is designed to evacuate heat by convection, characterized in that it also comprises a cover delimiting a channel in which a coolant circulates to ensure convection, the cover being joined to the heat sink and the printed circuit board, and in that the channel prevents the coolant from coming into contact with the electronic components.Type: GrantFiled: April 24, 2006Date of Patent: December 28, 2010Assignee: ThalesInventors: Gerard Nemoz, Olivier Leborgne, Serge Bernadac
