Cooling apparatus

Abstract

The cooling apparatus includes: a liquid storage tank receiving and storing a liquid; a. cooling pipe taking heat from the liquid stored in the liquid storage tank to cool the liquid; a refrigerating cycle supplying a low pressure refrigerant gas to the cooling pipe; and a fluid flow guiding unit installed within the liquid storage tank, preventing a liquid introduced into the liquid storage tank from being mixed with a liquid which has been previously introduced to be cooled in the liquid storage tank, and guiding the water such that the water sequentially flows to an outlet of the liquid storage tank. The fluid flow guiding unit includes a supporter placed along an internal central portion of the liquid storage tank; and a spiral plate installed along an outer circumferential surface of the supporter to guide the liquid introduced into the liquid storage tank to sequentially flow toward the outlet.

1 . A cooling apparatus comprising:
 a liquid storage tank having an internal space for storing a liquid;   an inlet pipe line supplying a liquid to the interior of the liquid storage tank, and an outlet pipe line for discharging water supplied to the liquid storage tank;   a cooling unit taking heat from the liquid stored in the liquid storage tank to cool the liquid; and   a fluid flow guiding unit installed within the liquid storage tank, preventing a liquid introduced into the liquid storage tank from being mixed with a liquid which has been previously introduced to be cooled in the liquid storage tank on the whole, and guiding the water such that the water sequentially flows to an outlet of the liquid storage tank.   
     
     
         2 . The cooling apparatus of  claim 1 , wherein the fluid flow guiding unit includes a supporter placed along an internal central portion of the liquid storage tank; and a spiral plate installed along an outer circumferential surface of the supporter to guide the liquid introduced into the liquid storage tank to sequentially flow toward the outlet. 
     
     
         3 . The cooling apparatus of  claim 2 , wherein a pipe line is insertedly positioned within the supporter in order to supply a liquid to the interior of the liquid storage tank or discharge the liquid from the liquid storage tank. 
     
     
         4 . The cooling apparatus of  claim 1 , wherein the cooling unit is a refrigerating cycle having a cooling pipe wound in a form of coil in the liquid storage tank. 
     
     
         5 . The cooling apparatus of  claim 1 , wherein the liquid introduced into the liquid storage tank is any one of water, a beverage, and alcohols. 
     
     
         6 . The cooling apparatus of  claim 1 , wherein an end portion of the inlet pipe line is positioned at a lower end within the liquid storage tank, and an end portion of the outlet pipe line is positioned at an upper end of the liquid storage tank. 
     
     
         7 . The cooling apparatus of  claim 1 , wherein the end portion of the inlet pipe line is positioned at the upper end within the liquid storage tank, and the end portion of the outlet pipe line is positioned at the lower end of the liquid storage tank. 
     
     
         8 . The cooling apparatus of  claim 7 , wherein the end portions of the inlet pipe line and the outlet pipe line are bent toward an inner face of the liquid storage tank. 
     
     
         9 . The cooling apparatus of  claim 1 , wherein a filter unit is provided in the inlet pipe line.
