EXPERIMENTAL STUDY OF PCM BASED HYBRID HEAT SINK FOR ELECTRONIC COOLING

The present experimental study reports the thermal performance analysis of a phase change material (PCM)-basedfinned heat sink placed on silicone rubber heater which mimics CPU chip and is cooled by natural forced convection. subjected to constant cyclic loading for five input power values (4, 6, 8, 10, 12 W). Paraffin wax 1-hexadecanol are selected as PCM this study, have melting points in ranges 58°C?60°C 48°C?50°C, respectively. steady-state transient base temperature behavior indicated that with performed better than without under convection load. With increase power, time reduced. Between two PCMs, filled operation. It was observed offers insight into sinks at different inputs. total operation takes less paraffin-filled during when For loading, reduced factor 0.41 0.43 times compared paraffin 1-hexadecanol,
