Abstract:

The rapid advancements in microsystems technology have necessitated the exploration of innovative materials for efficient thermal management in micro heat exchangers. This research delves into the performance evaluation of three advanced ceramics: ZrB۲, BeO, and Si۳N۴ as alternative micro heat exchanger fabrication materials. The study systematically assessed the ceramics' interaction with Al۲O۳-nanofluids across diverse volume percentages and mass flow rates using the Taguchi optimization method. Beryllium oxide emerged as the superior material, registering warm outlet temperatures as low as ۶۴.۸۶ °C and cold outlet peaks at ۳۱.۶۸ °C. Sensitivity analyses further underscored the critical role of inlet temperature on outlet dynamics, with warm and cold outlets showing significances of ~۷۲% and ~۹۹%, respectively. Additionally, the research pinpointed ۰.۷۵ vol% as the optimal Al۲O۳-nanofluid content, yielding the most favorable performance metrics across the ceramics.The rapid advancements in microsystems technology have necessitated the exploration of innovative materials for efficient thermal management in micro heat exchangers.
