Abstract:
Boiling heat transfer on the flame spraying porous surface was experimentally studied. The tested spraying porous layers were made of gear bronze with three different thickness. Distilled water, ethyl alcohol and R-113 were used as working liquids. The experimental was performed at the saturated temperature under local atmospheric pressure. The experimental results show that for such porous layer, the wall superheat required to initiate boiling is low, the boiling heat transfer coefficient can be higher than that of smooth plane surface by about twofold to fivefold. At the same time, the critical heat flux of such spraying porous layer is also higher than that of smooth plane, and it can enhance the boiling heat transfer within wide heat flux range. The experiment also reveals that the boiling hysteresis is not serious. The spraying technique not only has the advantages of simple equipment, convenient operation and low cost, but also can be suited for irregular base surface with complex geometry shapes. So, the spraying porous surface is a promising type of wick structure for heat pipe and vapor chamber.
