Heat Spreading Analysis of a Heat Sink Base Embedded With a Heat Pipe

A simplified theoretical model predicting the heat transfer performance of a heat sink base embedded with a flat heat pipe is developed. Numerical analysis was performed using the commercial software FLUENT. The investigation indicates that for heat sink bases embedded with a typical heat pipe, the entire heat sink can be modeled as a flat plate with a uniform temperature and an effective convection heat transfer coefficient. The prediction is compared with the experimental data obtained previously.
