CURCUIT FOR COOLING HIGH-BEAT AREAS OF STRUCTURES

摘要

FIELD: power industry. ^ SUBSTANCE: circuit for cooling high-beat areas of structures consists of internal profiled shell, on external surface of which there are made ribs of cooling circuit, and of external profiled shell installed on internal one and bound with it by tops of ribs. Blades parallel to a bottom of a slot are made on tops of the circuit ribs; also external profile of blades corresponds to internal profile of the external shell. Blades tie tops of two adjacent ribs between them to increase strength and stability of shells. Also blades interconnect tops of all ribs forming single circular surface. For improvement of conditions of heat release lengthwise ribs are made on internal fire surface of the internal shell. ^ EFFECT: increased stability and durability of internal and external shells. ^ 4 cl, 4 dwg
