Abstract
A device for producing single-crystal ingot, provided with coolers (19) using a piping system through which cooling water failure caused by water leakage and at the same time to find out conditions for maximizing a production efficiency, the coolers (19) are disposed at portions of the inner sides of thermal shielding elements (18) and the lower ends (19a) of cooling pipes are so set as to be positioned up to 150 mm high from the surface (12a) of molten silicon liquid.
