COOLING DEVICE OF ELECTRONIC COMPUTER

摘要

PURPOSE:To execute corrosion pre-inhibition of a cooling device by replenishing a corrosion inhibitor corresponding to a measured result of an absorption characteristic of white light out of a mixed corrosion inhibitor added to a cooling water. CONSTITUTION:The mixed corrosion inhibitor consisting of BTA and a molybdate is added to a cooling water 1 in the cooling device 5 of an electronic computer, the absorption characteristic of the white light out of respective corrosion inhibitors is measured and the corrosion inhibitor is replenished in the cooling water corresponding to the measured absorbance value in respective wave lengths. Since the mixed corrosion inhibitor exists in the cooling water in the cooling device and the corrosion inhibitor is automatically replenished by detecting the concentration condition of the corrosion inhibitor, the corrosion of the cooling device is prevented.
