MULTI-COOLING DEVICE Russian patent published in 2001 - IPC

FIELD: power-plant engineering, applicable for cooling of surfaces being under the effect of alternating thermal load. SUBSTANCE: multi-cooling device has N members, each representing a body with ribs adjoining the cooled surface, positioned inside the body are the zones of evaporation and condensation, filled both with fine-pored and coarse-pored hydrophilic and hydrophobic material, respectively of the zone of conveyance of heated and cooled liquid, filled with capillary hydrophilic material, partition having the shape of a truncated prism with steam nozzles and ducts of the steam header made of hydrophobic material, cavity, the side walls of each member are adjacent walls of the other members adjoining it. EFFECT: expanded range of thermal load and provision of differentiated cooling of the heated surface. 1 dwg
