LIQUID RAPID COOLING DEVICE

摘要

A liquid rapid cooling device (1) is provided with: a cylindrical cooling pipe (31) that is capable of cooling an outer wall; a cylindrical coat pipe (21), which covers the cooling pipe (31), and which is capable of rotating with a rotation axis (Zr) at the center; and a liquid introducing path (73) that is capable of introducing a liquid into a gap (G) between the outer wall of the cooling pipe (31) and an inner wall of the coat pipe (21). Furthermore, a surface temperature of the outer wall of the cooling pipe (31) is reduced to a temperature equal to or lower than a solidifying point of the liquid. The coat pipe (21) has a spiral protruding section (22) on the inner wall.
