Claims

[Scope of utility model registration request]

In an electronic device in which a part of the device requires rotation and the rotating portion includes an electronic device that requires liquid cooling with a coolant, a first pump that pumps the coolant under pressure and a pump that supplies the coolant to the non-rotating portion. A heat exchanger for cooling, a cooling liquid feed pipe that passes from a non-rotating part through the vicinity of the rotational axis of the device to the rotating part, and has its end released downward in the rotating part, and a rotating shaft. a first reservoir tank with an open upper part located on the axis of the cooling liquid feed pipe; A second reservoir tank with an open upper part, a second pump for pumping the coolant, and a second reservoir tank that passes over the rotational axis of the rotating part and is located at the upper part of the first reservoir tank provided in the non-rotating part. a coolant return pipe from which the coolant is released, the coolant in the first reservoir tank of the non-rotating part being pumped by the first pump and cooled through the heat exchanger; After being discharged into the second reservoir tank, it is pumped from the second reservoir tank by the second pump, flows inside the electronic equipment in the rotating part, removes heat from the equipment, and returns to the An electronic device characterized in that the electronic device is configured to return to the first reservoir tank of the non-rotating part through a side pipe.
