PROBLEM TO BE SOLVED: To provide a liquid cooling device of a sealed type that can avoid probability of process water contamination, ensuring heat exchange efficiency equal to or higher than that of an open type device, and having a compact structure as a whole.SOLUTION: A liquid cooling device 1 includes: an oblong casing 2 in an inner lower portion of which cooled liquid is stored, and through an inner upper portion of which air passes; a rotary cylinder 6 rotatably and laterally provided in the casing 2; rotating means for axially rotating the rotary cylinder 6; and a ring fin 6 protruding from an outer circumference of the rotary cylinder 6. The ring fin 7 or/and the rotary cylinder 6 are formed so that the cooled liquid stored in the casing 2 can adhere to and spatter on the ring fin 7 or/and the rotary cylinder 6 by rotation driving of the rotating means until a lower portion of the ring fin 7 or the lower portion of the ring fin 7 and that of the rotary cylinder 6 are immersed. |
