<p>The present invention relates to a cooling device capable of maximizing cooling efficiency by guiding a cooled liquid, which is to sequentially flow, to be stored without being mixed with a room-temperature liquid that is newly introduced. The cooling device of the present invention comprises: a liquid storage tank into which a liquid is introduced and stored; a cooling pipe for cooling the liquid stored in the liquid storage tank; a cooling cycle supplying a low-pressure refrigerant gas to said cooling pipe; a liquid flow guiding means installed inside said liquid storage tank and guiding a liquid introduced into the liquid storage tank to sequentially flow into an outlet of the liquid storage tank while preventing the liquid from being mixed with the cooled liquid in the liquid storage tank. Said liquid flow guiding means consisting of a supporter positioned along the inner central portion of the liquid storage tank, and a spiral plate fixed to an outer surface of said supporter and guiding the liquid introduced into the liquid storage tank to sequentially flow into the outlet.</p> |
