Patent ID: 8720531

Claim:
An electronic device cooling apparatus that diffuses heat generated from a heat generating component by circulation of a cooling medium to carry out cooling, said electronic device cooling apparatus comprising: a cooling device comprising a heat conductive plate formed with a flow path for the circulation of said cooling medium, a circulating pump for circulating said cooling medium, and a liquid storage tank for reserving in advance the cooling liquid in an amount corresponding to expected liquid permeation and air for suppressing the internal pressure, said heat conductive plate comprising a lower plate including a groove of a predetermined pattern according to the flow path, and an upper plate placing over the lower plate so as to face the groove, said storage tank comprising: a one liquid storage tank upper chamber provided on the upper side of the heat conductive plate, a one liquid storage tank lower chamber provided on the lower side of the heat conductive plate, a branch hole provided with the upper plate and branched from the flow path that connects the flow path and the liquid storage tank upper chamber, and a bypass provided with the heat conductive plate so as to allow said cooling medium to pass through the liquid storage tank upper chamber and the liquid storage tank lower chamber.
