Abstract:
A liquid cooling system, comprising:a circulation pump of the pulsation type for circulating cooling liquid therethrough including an input portion for receiving cooling liquid and a separate output portion for supplying cooling liquid; a heat receiving jacket supplied with said cooling liquid and disposed to receive heat generated from a heat generating body; a heat radiation portion for radiating heat which is supplied by the cooling liquid passing through said heat receiving jacket; and a member for circulating the cooling liquid passing through said heat radiation portion into said pump so that said cooling liquid circulates within a closed flow passage, wherein &Dgr;Vs is equal to or greater than &Dgr;Vp, with the inner volume change when said pump emits a pulsation therefrom being represented by &Dgr;Vp, the pressure caused by said volume change being represented by P, and the volume change due to said pressure P which occurs in the flow passage of the cooling liquid, other than in said pump, being represented by &Dgr;Vs.
