OBJECT PASSIVE TEMPERATURE CONTROL SYSTEM Russian patent published in 1995 - IPC

FIELD: space engineering. SUBSTANCE: temperature control system consists of radiator connected with condensing zone of thermal pipe of varying conductivity, heat accumulator TA₁ and heat pipe lines connecting the heat accumulator with thermal pipe of varying conductivity; system is also provided with additional heat accumulator TA₂, which is in thermal contact with evaporation zone of thermal pipe of varying conductivity. Heat accumulators TA₁ and TA₂ are filled with substances having different melting points T₁ and T₂, and are connected with minimum and maximum preset temperatures of the object T_min and T_max and with temperature of evaporation zone of the thermal pipe of varying conductivity at the following relationships T_o< T₁< T_max,, T_з< T₂> T_min where T_o is maximum temperature of evaporation zone of thermal pipe of varying conductivity at which its thermal conductivity is minimum; T_ev.z is minimum temperature of evaporation zone of thermal pipe of varying conductivity at which its thermal conductivity is maximum. EFFECT: enhanced reliability. 1 dwg
