COVER OF INGOT GROWER CHAMBER

摘要

PURPOSE: A cover of an ingot grower chamber is provided to achieve a cover adapted for the ingot grower chamber having superior pressure resistance characteristic and to enlarge a viewing angle by forming first and second windows. CONSTITUTION: A cover of an ingot grower chamber includes a cover body(100). The cover body(100) has a dome shape and is divided into an inner cover section(102) and an outer cover section(104), which are coupled to each other while being spaced from each other by a predetermined distance in such a manner that a cooling water flowing path is formed between the inner and outer cover sections(102,104). Cooling water flows through the cooling water flowing path. First and second view ports(108a) are formed by passing through the inner and outer cover sections(102,104). A flow rate varying device is provided at a predetermined portion of the cooling water flowing path so as to vary flow rate of cooling water.
