Abstract
An electronic apparatus includes a case mounting a semiconductor element within an inside thereof, a heat-receiving member thermally connected with the semiconductor element, a heat-radiation member disposed on an inner side surface of the casing, and a liquid driver for driving a liquid coolant between the heat-radiation member and the heat-receiving member. The apparatus further includes a tank accumulating the liquid coolant therein with at least a predetermined volume of the coolant to delimit a coolant surface within the tank, wherein the tank, the heat-radiation member and the heat-receiving member are connected with tubes, and a suction end portion of a suction pipe connected into the tank is located at a position which is always below the coolant surface irrespective of change of position of the tank.
