Abstract
A liquid cooling system, enabling protection from corrosion due to liquid coolant for a long time-period (5–10 years) while cooling a heat-generation body effectively, comprises a pumpa heat-receiving jacketa radiator for radiating heat into an outside, being made up with a heat-radiation pipeand a heat-radiation plateand further a tankfor accumulating the liquid coolantwithin an inside thereof, wherein those are connected in a closed-loop, so as to circulating the cooling liquid therein, thereby cooling the heat-generation of a CPUbeing a heat-generation element, effectively, through the heat-receiving jacketand further a water-permeable bagis disposed in a portion of flow path of the cooling liquid, which receives microcapsulestherein, each enclosing in an inside thereof anti-corrosion agentfor suppressing the corrosion due to the cooling liquid, including such as, a water, etc.
