Abstract

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.

First claim

What is claimed is:

1 . A water-cooled server, comprising:
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, wherein an elastic force applied to the piston by the elastic member is smaller than maximum pressure applied to the piston by the cooling water.

2 . The water-cooled server according to claim 1 , wherein:
a coupling part between the drainage branch tubing and the cooling main tubing and an arrangement part of the second end in the cooling main tubing are respectively disposed at both sides of a cooler of the water-cooled server.

3 . The water-cooled server according to claim 1 , wherein:
the second end of the piston is disposed adjacent to a water inlet of the cooling main tubing, and a coupling part between the drainage branch tubing and the cooling main tubing is disposed adjacent to a water outlet of the cooling main tubing.

4 . The water-cooled server according to claim 1 , wherein:
the elastic member is a spring that is disposed in the drainage branch tubing and applies a pulling force to the first end of the piston.

5 . The water-cooled server according to claim 1 , further comprising:
a barrier movably disposed at the drainage branch tubing and capable of blocking the first end of the piston.

6 . The water-cooled server according to claim 6 , wherein:
the barrier is a needle.

7 . An electronic device, comprising:
a water-cooled server, wherein 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, wherein an elastic force applied to the piston by the elastic member is smaller than maximum pressure applied to the piston by the cooling water.

8 . The electronic device according to claim 7 , wherein:
a coupling part between the drainage branch tubing and the cooling main tubing and an arrangement part of the second end in the cooling main tubing are respectively located at both sides of a cooler of the water-cooled server.

9 . The electronic device according to claim 7 , wherein:
the second end of the piston is disposed adjacent to a water inlet of the cooling main tubing, and a coupling part between the drainage branch tubing and the cooling main tubing is disposed adjacent to a water outlet of the cooling main tubing.

10 . The electronic device according to claim 7 , wherein:
the elastic member is a spring that is disposed in the drainage branch tubing and applies a pulling force to the first end of the piston.

11 . The electronic device according to claim 7 , further comprising:
a barrier movably disposed at the drainage branch tubing and capable of blocking the first end of the piston.

12 . The electronic device according to claim 11 , wherein:
the barrier has a needle shape.
