Abstract
The present work reports an experimental investigation of heat transfer characteristics of a closed-loop two-phase thermosyphon (CLTPT) system with a structured heating surface. A novel structured heating surface, i.e., segmented finned microchannels, has been used to promote heat transfer rate, and its performance has been compared with that of plane heating surface. Compared with the plane heating surface, the segmented finned structured heating surface produces an enhancement of 157% in heat transfer coefficient (HTC), whereas it produces a 145% enhancement in the critical heat flux (CHF). The present structured surface also delivers better heat transfer performance compared with the available data in the literature.
