摘要
Comprehensive numerical analysis is reported for phase change material (PCM) based heat sink coupled with a model heat pipe as thermal conductivity enhancer (TCE). The heat pipe is modeled considering a fixed liquid–vapor interface and solving the Navier–Stokes equations in domain-specific formulations applied to the solid wall, the porous wick, and the vapor core. The porous wick is modelled using the extended Darcy–Brinkman–Forchheimer formulation, accounting for both viscous and inertial effects in the saturated porous structure. The estimated effective thermal conductivity of the heat pipe is used when coupled with the phase change based heat sink where the phase change process of PCM is modeled using an enthalpy–porosity approach. An in-house test facility is developed for validating the numerical results. The results demonstrate that the PCM-embedded heatsink coupled with a heat pipe (as TCE) maintains the base temperature below the set point for an extended period. Additionally, with the coupled heat pipe configuration full utilization of the PCMs latent heat storage capacity is ensured which in turn promotes the charging cycle. For applicability to real life electronic devices, the simulation results are analyzed in terms of non-dimensional numbers including Fourier number, and modified Nusselt number.
