Inhalt:
Three types of cooling methods were compared for Hitachi’s latest low inductive housing 2in1 module called “next High Power Density Dual (nHPD2)” considering inverter layout. The first is an air-cooled type, the second is a conventional water-cooled type (called ‘indirect-watercooled’ type), and the third is a water-cooled type without using thermal grease (called ‘direct- water-cooled’ type). The trade-off curve between thermal resistance and pressure drop was smallest when the direct-water-cooled nHPD2 was used. The thermal resistance of direct- water-cooled type was half which resulted in electric current output doubling comparing to indirect-water-cooled type.
