In this investigation, high current levels were applied to an IGBT and, using spray cooling, a heat flux of 825W/cm2 at the die was achieved. Current and heat flux levels achieved during this investigation could not have been done using ordinary cooling methods. The techniques used in this investigation clearly demonstrate the superior cooling performance of spray cooling over traditional cooling methods.
