Claim:
1. A cooling device for cooling a shrinking assembly previously subjected to a heat application comprising: a shrink chuck into which a shank of a tool is clamped or from which the shank of the tool was unclamped; a first substantially closed circuit, said first substantially closed circuit comprising a pump in the form of a fan, a carrier gas channel interconnecting a pressure side of the pump to a cross flow cooling chamber, and the cross flow cooling chamber connecting to a suction side of the pump for creating a carrier gas flow; and a second substantially closed circuit, said second substantially closed circuit comprising a liquid cooling agent path and said cross flow cooling chamber for circulation of a liquid cooling agent; said first substantially closed circuit and said second substantially closed circuit overlapping at said cross flow cooling chamber, wherein said carrier gas flow and said liquid cooling agent are combined to create a coolant flow mixture; wherein said coolant flow sweeps over at least a section of the shrink chuck to cool said shrink chuck, and wherein downstream of said cross flow cooling chamber, said coolant flow mixture separates to become said carrier gas flow within said first substantially closed circuit and said liquid cooling agent within said second substantially closed circuit.
