We present our results of experimental research of the influence of characteristics of metal capillary structures (CS) connected with solid heating surfaces in imitation of the operation of heat pipes. The aim of the investigation was to determine the influence of a way of connection of various structures on the value of thermal resistance R in the places of «CS-surface» contact. Our results generalized as empirical formulas are necessary for designing heat pipes of space purpose.
