Optimization analysis of a disk-shaped heat pipe

An optimized disk-shaped heat pipe design based on the parametric study and the analysis of boiling limitation is presented. A pseudo-three-dimensional analytical model was formulated for the parametric study of the maximum heat transfer capacity of the heat pipe. Results show that, for a fixed heat pipe thickness, the optimized flow channel angle, top and bottom wick thickness, vertical wick thickness, and shape parameter of the vertical siches exist for which the capillary limit of the pipe is at its maximum value.
