COOLING SYSTEM FOR TRANSPORT FACILITY ENGINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: cooling system is provided with bypass pipe line with flow rate thermoregulator fitted in circulating loop including bumper made in form of finned box with partitions and semiclosed chamber. Circulating loop is formed by successive connection of inlet or outlet manifold of radiator, bumper, bypass pipe line and suction branch pipe of liquid pump; thermal accumulator is located in at least one chamber formed by means of partitions in bumper chamber. Partitions are made in form of tubular elements and thermal accumulator is made of discretely distributed heat accumulating spherical bodies of negative and positive buoyancy. EFFECT: cooling system is characterized by enhanced heat accumulating and heat dispersing properties; system intensifies warming-up of engine from external heat source, enhances distribution of cooling liquid in hot and cold loops at modular construction of radiator and reduces hydraulic resistance due to circulating loop. 3 cl, 4 dwg
