COATED GRAPHITE HEATER CONFIGURATION

摘要

A coated graphite heater. The heater has a configuration comprising a plurality of heating rungs having a major portion disposed substantially parallel to an upper surface of the heater so that the major portion is disposed horizontally. The heater configuration provides a heater that exhibits reduced thermal stress and/or reduced CTE mismatch stress particularly compared to designs having heating rungs with a major portion oriented perpendicular to the plane of the upper surface of the heater.
