  • Apparatus for manufacturing poly crystaline silicon ingot for solar battery having door open/close device using hinge
    Patent number: 8192544
    Abstract: Disclosed herein is an apparatus for manufacturing a polycrystalline silicon ingot for solar batteries having a door control device using a hinge. The apparatus includes a vacuum chamber, a crucible, a susceptor which surrounds the crucible, a heater which heats the crucible, and an insulation plate which is disposed below the susceptor and has an opening therein. The apparatus further includes a cooling plate which moves upwards through the opening of the insulation plate and comes into close contact with or approaches the lower end of the susceptor, a cooling plate moving unit which actuates the cooling plate, a temperature sensor which measures the temperature of the crucible, and a control unit which controls the temperature in the crucible and the cooling plate moving unit. Furthermore, a door is provided on the insulation plate to open or close the opening of the insulation plate. The hinge is provided between the door and the insulation plate.
