Inclusive Innovations in Thermal Management: Advancing High- Power Electronics Through Diverse Material and Cooling Technologies

With the trend towards miniaturization in electronics to meet modern demand for betterperformance and portability, power densities have risen sharply, creating major challenges inheat management. Conventional cooling methods such as passive heat sinks, forcedconvention and legal thermal interface materials (TIMs) are falling short of managing thethermal loads generated by compact, high-power components. This paper provides anoverview of advanced and emerging thermal management strategies that enable moreequitable access to high performance computing and sustainable electronics design. Itencompasses a diversity of tactics such as liquid cooling with micro-channel cold plates, twophaseand immersion cooling and the integration of nanomaterial-enhanced TIMs. Newmaterials like boron arsenide, synthetic diamond and 2D hexagonal boron nitride (h-BN)coatings are explored for their ability to enhance heat dissipation and improve deviceperformance. Additionally, cutting-edge designs like through-chip microchannels, directbondedheat sinks and dielectric coatings for water cooling highlight how design diversity cancater to different applications, device shapes and resource constraints. Leveraging on theknowledge from thermofluid dynamics, material science and electrical engineering, this studysupports fair and inclusive technology progress, as a result enhancing thermal performanceand device reliability. It also elaborates on the democratization of high-density powerelectronics.
