A water-cooled server and an electronic device are provided. The water-cooled server comprises a cooling main tubing, wherein the cooling main tubing guides cooling water; a drainage branch tubing operatively coupled to cooling main tubing; a piston having a first end disposed in the drainage branch tubing and a second end disposed in the cooling main tubing, wherein the first end drives the second end to a first position under pressure of the cooling water to prevent the second end from plugging the cooling main tubing; and an elastic member operatively coupled to the piston, wherein the elastic member drives the second end of the piston to move to a second position to plug the cooling main tubing. An elastic force applied to the piston by the elastic member is smaller than maximum pressure applied to the piston by the cooling water.

Water-cooled server and electronic device

A cooling system includes a first heat exchanging component configured to connect to a heat source and obtain heat of the heat source by heat transfer, to dissipate heat of the heat source; and a first pipe configured to connect to the first heat exchanging component and a second heat exchanging component and form a loop between the first and second heat exchanging components, and to transfer the heat obtained by the first heat exchanging component to the second heat exchanging component via the loop. A first position relationship is provided between the first heat exchanging component and the second heat exchanging component, to allow a cooling liquid in the first pipe to automatically flow into the second heat exchanging component after the cooling liquid exchanges heat with the first heat exchanging component, to transfer the heat generated by the heat source to the second heat exchanging component.

Cooling system and server

One embodiment provides rotating shaft, including: a spindle comprising an internal first channel; a wheel casing operatively coupled to the spindle, wherein the wheel casing comprises an internal second channel; and a bearing housing the spindle, comprising a third channel located between the bearing and the spindle; wherein the first channel, the second channel, and the third channel are located to form an enclosed annular channel configured to hold a substance. Other aspects are described and claimed.
