Heat transfer analysis and evaluation for two-phase flow in porous-channel heat sinks
- Texas A and M Univ., College Station, TX (United States). Dept. of Mechanical Engineering
Presented here are the results of a heat transfer analysis of two-phase heat dissipation utilizing high-conductivity porous channels as a heat sink. 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 surface of the porous channel result in a high heat transfer coefficient. In addition, the surface temperature was shown to remain quite uniform. Overall, the results confirm the expectation that the use of two-phase heat dissipation in high conductivity porous channels may be an acceptable cooling technique for future electronic devices where much higher heat fluxes than the present levels need to be removed effectively.
