Study on heat transfer performance of an aluminum flat plate heat pipe with fins in vapor chamber

Abstract

The heat transfer performance of a novel flat plate heat pipe (FPHP) for electronic cooling was investigated experimentally. A variety of performance tests of FPHP were carried out with different air flow velocities (1.5m/s<u<6m/s), working fluid filling ratios (10%<FR<50%), and the vacuum degrees (0.002Pa<VD<0.25Pa). Using distilled water and acetone as working fluids, the influence of the above parameters on steady-state heat transfer characteristics of the FPHP was also examined. The experimental results indicated that the filling ratio and vacuum degree had a significant influence on thermal performance of FPHP. Compared with cooling performance using distilled water and acetone, the FPHP cooling component using acetone had a stronger heat dissipation capacity for the same filling ratio.
