Miniature heat-pipe thermal performance prediction tool – software development

Abstract

The software for flat miniature heat-pipe parameters ( Q max, R hp, temperature field along the pipe surface, heat transfer coefficients in the evaporator and condenser zones h e, h c, etc.) prediction and numerical modeling was developed. The experimental data received for the flat miniature heat pipe (2.5–4 mm thickness, 50–250 mm length, 8–11 mm width) with a copper sintered powder wick saturated with water were compared with the data of numerical analysis and results showed that experimental verification testifies the validity of the software application.
