Abstract
A mono-crystalline silicon growth apparatus includes a furnace, a support base, a crucible, a heating module disposed outside of the crucible, and a heat adjusting module above the crucible. The heat adjusting module includes a diversion tube, a plurality of heat preservation sheets, and a hard shaft. The diversion tube includes a tube body and a carrying body connected to the tube body. The heat preservation sheets are sleeved around the tube body and are stacked and disposed on the carrying body. The hard shaft passes through the tube body and does not rotate. The hard shaft includes a water flow channel disposed therein and a clamping portion configured to clamp a seed crystal. Therefore, a fluid injected into the water flow channel takes away the heat near the clamping portion. A heat adjusting module and a hard shaft of the mono-crystalline silicon growth apparatus are provided.
