Miniature heat-pipe thermal performance prediction tool – software development

The software for flat miniature heat-pipe parameters (Qmax, Rhp, temperature field along the pipe surface, heat transfer coefficients in the evaporator and condenser zones he, hc, 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.
