摘要：

The paper is focused on the working mechanism of micro-heat pipe arrays (MHPAs), which are new efficient phase transition components. The three-dimensional partition-minuteness model is made to analyze the flow and heat transfer in the MHPAs by using the theory of two-phase closed thermosyphon and the theory of condensation on vertical walls with micro-channels. The surface tension is considered in the model. Through partitioning the condensate on the surface of microchannels, the flow and heat transfer are analyzed, giving the thickness of condensate, temperature distribution and mass flux. The Matlab programs based on the three-dimensional partition-minuteness model are used. The calculation results agree with the experimental results. The error is within 5%. The formulas for the saturation temperature in the condensation part of the MHPA are obtained from the calculated results. © All Rights Reserved.
