Abstract

PURPOSE: To stabilize water temperature control by making the capacity of heat-exchange in a heat-exchanger variable.
CONSTITUTION: When the secondary cooling water within the cooling pipe 26 in a cooling unit 31 is cooled by the primary cooling water from the primary cooling the supply unit and fed to a cooled body 20 in an electronic device 32 by a pump 4, the cooling pipe 26 will be long, with the first and second cooling pipe 26a and 26b continued if the valve (A) 21 is open and the valve (B) 22 is closed, and it will be short, with only the second cooling pipe 26b effective if the valve (A) 21 is closed and the valve (B) 22 is open. When the heat capacity of the electronic device is low heat production and the flow rate required by the electronic device is low flow rate, it is possible to make the heat-exchange rate low by making the heat-conduction area within the heat- exchanger small, and to perform anti-condensation measurement by making the temperature drop of the electronic device small.
