Numerical Simulation of Vapor-Liquid Two-phase Flow and Heat Transfer Within A New Type of Heat Pipes for Spaced Heat Sources

A structurally new type of cold plate fitted heat pipe has been developed to effectively solved the problem of heat dissipation by array- arranged conduction antennas for multifold heat sources with a high heat flux. A model to simulate the flow and heat transfer of liquid-vapor two-phase flow in the cold plate fitted heat pipes has been set up, and numerical simulation is performed in IPSA algorithm for the flow and heat transfer characteristics in the pipe and plate for spaced heating sources. By numerical simulation and experimental verification, the performance behavior of the newly designed cold plate fitted heat pipes have been elementarily investigated to serve as a reference for later application.
