Presented are the results of a heat transfer analysis of two-phase heat dissipation using a high-conductivity porous-channel heat sink. In the analysis, a consistent set of conservation equations based on phase-averaged properties of the fluid are derived from the conventional ones and solved numerically by the finite volume method. The results indicate that the high conductivity and large solid-fluid contact area of the porous channel result in a high heat transfer performance for two-phase heat dissipation, which may be an alternative to cooling techniques for microelectronics with high heat flux.
