| titleOfInvention | Three-phase graphite tubular heater |
| abstract | FIELD: heating systems. n SUBSTANCE: invention refers to resistance heaters and can be used for single crystal growing of silicone carbide. Thickened upper attachment part (1) is intended for connecting heater segments to current leads. Heat-generating middle part (HMP) (2) is divided with dead-end slots (DES) (3). Thickened lower annular element (TLAE) (4) connects three segments of heater as per star-connected circuit. Between upper edge (5) of thickened lower annular element and external surface (6) of heat-generating middle part (2) wall there is slope (7) at α angle equal to 55°-63°. Cross-section area of one segment (8) of heat-generating middle part (2) divided with dead-end slots (3) is equal to half-area of longitudinal section of thickened lower annular element (4). It is more preferable when wall thickness of thickened lower annular element (4) is more than wall thickness of heat-generating middle (2) by not less than 1.4 times. n EFFECT: invention solves the problems of simplification of fabrication and increase in life time. n 2 cl, 5 dwg |
