METHOD OF CONTROL OF TEMPERATURE LEVEL OF LOOP THERMAL TUBE Russian patent published in 1996 - IPC

FIELD: thermal stabilization of various thermally-loaded objects. SUBSTANCE: temperature control of thermal tube is effected by means of controllable thermal action on heat-transfer agent in compensation chamber. Action is effected by heating or cooling the heat-transfer agent controllable according to definite law. Power of control action may be found from formula Q_p= C_regQ/L(T_cc2- T_cc1), where Q_p is power of control thermal action; W; C_reg is heat capacity of liquid heat-transfer agent, J/kg K; Q is heat flow transferred to by thermal tube, W; L is latent evaporation heat of heat-transfer agent, J/kg; T_cc1 is temperature of vapor in compensation chamber realizing at preset temperature of vapor in evaporation zone of thermal tube or heated wall of evaporator, K; T_cc2 is temperature of vapor in compensation chamber realizing at preset conditions of supply and removal of heat in evaporator and condenser of thermal tube, K. Power may be set by means of automated system at feedback by temperature of vapor in vapor line or wall of evaporator. EFFECT: enhanced reliability.
