Liquid Cooling for High Power Modules

Modern converters, transport systems, electric vehicles and alternative energy generators benefit from the increasingly efficient wide bandgap electronics, which are optimized for operation at higher switching frequencies and temperatures and feature a much more compact design.

Thus Mersen developed IsoMAXX – a vacuum brazed cold plate with unique features: The average thermal resistance is 6 K/kW, and at ~600 mbar, the pressure drop is substantially lower than that of all previous models. IsoMAXX cold plates ensure an optimal temperature range for power electronics, in which all single chips and modules on the cold plate remain at the same temperature. IsoMAXX helps development engineers to design solutions with increased efficiency and a minimal footprint: No minimum clearance is required between modules, which allows versatile integration regardless of the number of modules needed for the particular application.


R-TOOLS MAXX is a no-charge, on-line simulation software that allows users to model the optimum air or liquid cooled heat sink solution tailored to your project requirements. R-TOOLS MAXX generates a simulation of the most efficient heat sink model, and the simulation results aid in reducing design time and increasing the reliability of the finished heat sink product, all before the first prototype is even built.

R-TOOLS MAXX lets users input parameters of their application such as the temperature boundaries, size of the heat source (IGBT, SCR, etc.), layout of the power electronics, and several other design criteria. The program’s simulation engine will then output an air or liquid cooled heat sink design along with 3D visualization tools to provide users an overview of the heat sink thermal behavior and heat spread over the surface of the heat sink. This results in a more accurate technical solution compared to traditional data sheets and graphs.
