Patent ID: 7296618

Claim:
A liquid cooling system for use in art electronic apparatus including a heat-generating element therein, comprising: a pump for supplying a cooling liquid; a heat-receiving jacket, being supplied with said cooling liquid, for receiving heat from the heat-generating element; a radiator, being supplied with said cooling liquid passing through said heat-receiving jacket, for radiating heat therefrom; flow passages for circulating said cooling liquid in a route passing through said radiator back to said pump, said flow passages including parts that generate corrosive ions therefrom; and a tank for accumulating said cooling liquid circulating within said flow passages, wherein: the cooling liquid contained within said system is less than or equal to one liter in volume, an ion exchange bag, having water-permeable surfaces, encloses an ion exchange resin therein, and is disposed in the cooling liquid accumulated within said tank, and said ion exchange bag enables ion exchange through diffusion on almost all water-permeable surfaces thereof.
