Abstract

The research results of the influence of capillary structure characteristics on the heat transfer intensity in the heating zone of miniature heat pipes are presented in the paper. Also, the research results of the influence of heat removal conditions in the condensation area on the internal characteristics of phase transition processes are given. Copper heat pipes, filled with methanol were selected as experimental samples. The capillary structure was made of copper fibers with diameters of 50 microns and 70 microns, and the length of3 mmand7 mm.

The analysis of experimental data showed that the increase in fiber diameter by 1,4 times leads to the decrease in the heat transfer intensity more than by 15 %. At the same time, the essential influence of the length change on the vaporization process in the heating zone of heat pipe was not observed.

The obtained results can be used in designing passive cooling systems of radio-electronic equipment, based on the miniature heat pipes.
