Cooling liquids in closed containers without external energy input or output involves generating cooling power by rapidly expanding gas in pressurized cartridge immersed in liquid

摘要

The method involves no external input or output of energy and the cooling power is generated by rapidly expanding a gas (3) in a pressurized cartridge (2) immersed in the liquid (5) to be cooled. The liquid container and the pressurized cartridge form a mechanical unit.
