High-heat-flux liquid cooling of electronics with manifold microchannels: Thermal-hydraulic optimization and experimental validation

Bazmi, B., Joshi, S., Park, W. Y., Aflatounian, S., Lad, A. A., Liu, J., Shatskiy, E., Garimella, V. S., Tang, C., Lin, Y., Asheghi, M., Mantooth, H. A., Goodson, K. E., Miljkovic, N.

International Journal of Heat and Mass Transfer 268, 128924

A hotspot-aware, Pareto-optimized copper manifold microchannel cooler cuts pressure drop by 70–98 % and thermal resistance by 19–26 % versus the baseline, removes 208 W/cm² from a six-device GaN board, and reaches a cooling COP of 1.6 × 10⁶, with CFD within 3 % of experiment.
