APPLICATION OF A HEAT HYDRAULIC ACCUMULATOR TO THERMAL STABILIZATION OF THE EVAPORATION ZONE OF A HEAT PIPEN. N. Maklakov and S. M. Khramov UDC 62-71-462:536.423 The use of a heat hydraulic accumulator (HHA) for thermal stabilization of the evaporation zone of a heat pipe (HP) has been proposed. The experimental setup for investigation of the heat pipe with a heat hydraulic accumulator has been described. Results of the experiments on this assembly have been presented. It has been shown that the installed heat hydraulic accumulator allows thermal stabilization of the evaporation zone of the heat pipe to a precision of 1oC. Federal State Unitary Enterprise "M. V.
