Abstract
A liquid cooling system for a personal computer is suitable for cooling a semiconductor device, etc, generating high heat and is designed to suppress undesirable influence on the personal computer following corrosion in the liquid cooling system, thereby ensuring the dependability of the system as a whole. The liquid cooling system has a pump for supplying cooling liquid; a heat receiving jacket supplied with the cooling liquid and positioned to receive heat generated from a heat generation body; a heat radiation pipe for radiating heat which is supplied by the cooling liquid passing through the heat receiving jacket; and a passage for circulating the cooling liquid passing through the heat radiation pipe into said pump. The heat radiation pipe is made of a material having a corrosion resistance that is higher than that of the heat receiving jacket.
