Cooling System of Cabinet and the Method of Cooling the Cabinet

A method of cooling a cabinet, comprising the steps of:

• charging step:
• delivering liquefied gas to a main pipe, vaporizing the liquefied gas into cooling gas in the main pipe, and then delivering the cooling gas into a space of a cabinet via the main pipe, wherein the main pipe has a section sinking in cooling liquid of a pond, and the charging step is stopped when a predetermined quantity of the cooling gas is delivered to the cabinet;
• circulating step:
• delivering the cooling gas in the cabinet into a circulating pipe and delivering the cooling gas back to the cabinet via the circulating pipe when a temperature in the space of the cabinet is equal to or higher than a working temperature, wherein the circulating pipe has a section sinking in the cooling liquid of the pond;
• and
• filling step:
• stopping the circulating step when the temperature in the space of the cabinet is equal to or higher than a warning temperature, and then delivering the liquefied gas to the main pipe, vaporizing the liquefied gas into the cooling gas in the main pipe, and then delivering the cooling gas to the space of the cabinet via the main pipe until the temperature in the space of the cabinet equal to or lower than a reset temperature, wherein the warning temperature is higher than the working temperature and the reset temperature is lower than the warning temperature.
