Thermal Performance of a Compact Two-phase Thermospyhon: Response to Evaporator Confinement and Transient Loads

摘要

This study investigates the effect of evaproator confinement on the performance of an enhanced microstructure based thermosyphon, that has shown very high heat transfer rates (upto 100W/cm~2). The enhanced structure used demosntrates almost 2.5 times increasei n the heat trnasfer compared to a soild block of the same size. The top spacing between the microstructure and the cover of the evaporator was varied and tis effect on heat transfer was studied. The results for the effect of sidewall spacing show that the influence of confinement on the boiling performance of the microstructure is negligible.
