HEAT SINK FOR HEAT REMOVAL FROM FUSE DURING SINGLE-CRYSTAL GROWTH IN VACUUM GLASS BULB

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to devices used during crystals growth by direct crystallisation from melt in vacuum bulb for heat removal from the fuse, heat is generated during crystallisation. Heat sink is made as tube braiding 7 out of copper wire with diameter 0.1-0.3 mm installed on external surface of the bulb 1 at place with fuse 3 such that smaller part of the fuse 3 is not overlapped, and part of braiding 7 hangs from the bulb 1.EFFECT: reliable heat removal from the crystallisation front, increased probability of penetration of high quality single-block crystal, heat sink has simple design, is easy manufactured and operated.1 dwg
