COOLING DEVICE AND COOLING DEVICE OF ELECTRONIC APPARATUS USING MIXED WORKING FLUID

摘要

A cooling device comprising a heat receiver attached to a heat generating member and using a flow of coolant to rob heat from the heat generating member, a heat exchanger radiating off heat from the inflowing coolant to lower the temperature of the coolant, a first channel carrying the coolant from the heat receiver to the heat exchanger, a second channel carrying the coolant from the heat exchanger to the heat receiver, and a pump for making the coolant move, wherein, as the coolant, a mixed working fluid comprised of pure water or impure water containing nanoparticles plus ethanol to give an alcohol concentration of ethanol 0.1 mass % to 5 mass % is used to improve the freezing resistance.
