PURPOSE: To obtain a subcooler for supplying a liquefied inert gas to industrial processes by arranging a chamber with a flow control valve communicating with a liquefied gas source, a column packed with a liquefied gas provided below the chamber and a gas outflow tube surrounding the column. CONSTITUTION: When an inflow pipe 12 is connected to a liquefied gas source and a valve 10 is opened, a liquefied gas enters a chamber 15 and passes through an opening 20 and a column 22 to cool the interior thereof. Then, it is rapidly gasified to be released from a path 30. The liquid and the gas continue to flow in until the chamber 15 and the column 22 reaches a balance in temperature. When the balance in temperature is reached, a float 18 rises with a rise in the water level in the chamber 15 to close an inlet by a valve stem 16. When the vaporized foams ascend in an outer tube 28, the liquid in the column 22 is forcibly circulated to lower the liquid in the column 22. At this point, an evaporation occurs to lower the temperature of the liquid. With such an arrangement, a sub cooler is obtained to supply a liquefied inert gas to industrial processes. |
