Abstract

A system for cooling tools, workpieces or the like with liquefied gas, preferably carbon dioxide, which is delivered to the tool or to the workpiece in its liquid state. The liquefied gas is caused to vaporize as it comes into contact with the tool or the workpiece so as to effectively cool the same. The system includes an insulated tank (1) or a gas storage pressure vessel, means for vaporizing the liquefied gas either completely or partially prior to or during its transportation through conduit means (4) to a cooling unit (3, 5) which is located in the close proximity of the tool (6) or the workpiece and in which the gas is reliquefied. The liquefied gas is thus returned to the tool (6) or to the workpiece for cooling said tool or workpiece in conjunction with re-vaporization of the liquefied gas. The invention also relates to a method for use in cooling with liquefied gas.
