REACTOR FOR PRODUCTION OF POLYCRYSTALLINE SILICON CORES

摘要

FIELD: metallurgy. ^ SUBSTANCE: reactor comprises cooling tray 1 mounted on a supporting structure, cylindrical cover 2, consisting of three inner cooling jacket and outer cooling jacket 4, cooling guide ribs 5. Outer cooling jacket 4 consists of the segments, which are rigidly connected to each other and by the agency of cooling guide ribs 5 of inner cooling jacket 3 by welding. The structure is provided with means for supply 7 and offtake 8 of cooling environment and bulkhead 9 for attaching the cover to tray 1. Between outer cooling jacket 4, internal cooling jacket 3 and guiding ribs 5 the ring channels are formed, passing from one level to another in a spiral. ^ EFFECT: reduced weight of the reactor containment and improved cooling conditions of internal jacket. ^ 5 dwg
