Abstract
A loop heat pipe (LHP) is heat transfer devices whose operation principle is based on the evaporation and condensation of working fluid, and use the capillary forces to ensure the fluid circulation. In this study, we proposed a new flat evaporator structure and micro LHP with the evaporator thickness of 3mm was designed, fabricated and tested. And we present the three-dimension mathematical model of a flat evaporator of a micro-LHP which takes into account the structural peculiarities of the evaporator and the specific character of a one side heat load supply. The computational results from the mathematical model were compared with experimental data; there was good agreement between predicted and measured temperature distributions.
