Growing energy density 

Along with bettering the efficiency of energy modules, measurement miniaturization can also be an essential pattern in associated designs. Nonetheless, greater thermal density has accompanied the upper energy density. It’s clearly an element that can’t be ignored which designers haven’t solely needed to look towards rising effectivity however putting in cooling infrastructure on key heat-generating elements and modules to shortly dissipate thermal power. 

To deal with these challenges, P-DUKE has not solely addressed the requirement to shrink the dimensions of energy boards and PSUs but additionally upgraded most of the heatsinks that match its industry-standard packages. The brand new heatsinks — HS, HC1, HC2, and HC3 — have fins which can be designed and sized for considerably higher temperature adaptation, as proven in Determine 4.
