dc.description.abstractA liquid-vapor phase change in pool-boiling offers an efficient cooling mechanism, but a main challenge is the limited Critical Heat Flux (CHF), resulting from the hydrodynamic instabilities near the evaporator. To enhance this limit, the micro/nanoscale surface wetting/structural modifications have been employed, but the enhancement is only factor of 3 compared to that of the plain surface. In this study, a capillary-canopy wick with the monolayer wick is employed to separate vapor-liquid phases to assist the liquid coolant supply to the evaporator, aiming at further CHF enhancement with a minimal thermal resistance. The particle size, heights and distance of the liquid-artery wick effects are also examined using sintered-copper particles/mesh. Experimental results show a significant CHF enhancement with a reduced thermal resistance. This novel wick design provides a deep insight into an optimal design in order to improve CHF and minimize the thermal resistance for advanced thermal management systems.
