Capillary boosting for enhanced heat pipe performance through bifurcation of grooves: Numerical assessment and experimental validation

In this study, an enhanced heat pipe performance for grooved pipes has been demonstrated through capillary boosting with the introduction of bifurcation grooves. Wider grooves regularly branch to narrower such that total cross-sectional liquid flow area remains approximately same. Following computational framework drawn by a recently developed analysis toolbox (H-PAT), we develop numerical model tree-like groove architecture. Then utilize design flat-grooved one step at evaporator. To verify our findings, two and without are manufactured experimented under same conditions. Experimental results show can predict thermal quite accurately. The reveal be viable option better than standard straight which leads least 25% higher maximum transport capacity. effect number branching on temperature flattening across is also different evaporator lengths.
