LIQUID-METAL COOLING SYSTEM Russian patent published in 2003 - IPC

FIELD: power engineering, particularly in power plant cooling systems. SUBSTANCE: cooling system comprises pipelines some of which are inside heat source, pump and loop assembly with coolant. Coolant is initially in frozen state. Cooling system comprises coolant melting device which is disposed near pump, loop assembly and pipelines, situated outside heat source. Melting device is made as heat tube. Heat tube evaporation part is arranged into heat source. Pump, loop assembly and pipelines, situated outside heat source, are disposed along heat pipe condensation part. Heat pipe condensation part, pump, loop assembly and pipelines, situated outside heat source are closed by common heat-insulation means, particularly by screen or screen-and-vacuum insulation means. Heat pipe working substances are alkali elements, such as sodium, potassium and lithium. EFFECT: reduced power consumption for coolant melting by providing coolant melting and heat source actuating without utilization of electrical power. 3 cl, 4 dwg
