The mathematical model is proposed for calculation of temperature profiles in gas-controlled heat pipe body and thermodiodes with liquid bloking for steady and unsteady regimes. The results of numerical modelling of temperature profiles and control characteristics for heat conduction coefficients of body materiel 10...400 W/mK are presented. The review of results of the experimental study of heat pipes with copper and stainless steel metal-fibrous capillary structure is also submitted for the purpose of temperature control.
