Abstract


The paper describes experimental studies on the heat transfer performance of a wickless vapor chamber with a heat sink. A vapor chamber of 78 mm length and 64 mm width was fabricated with a thickness of 5 mm and tested for two different working fluids, copper-water and aluminium-water nanofluids with the filling ratio of 30% of the vapor chamber volume. As a baseline comparison de-ionized (DI) water is considered as a working fluid. The vapor chamber was tested for heat inputs ranging from 90 W to 150 W. The effects of heat input and metal concentration in the working fluids and the effect of particle deposition on the performance of the vapor chamber are presented.
