Abstract

A water-replenishing and gas-removing structure for water cooling device includes a flow-guiding main body having a water-receiving space as well as an inlet, an outlet, a first opening and a second opening, which are communicable with the water-receiving space. The first and the second valve member are located in the water-receiving space corresponding to the first and the second opening, respectively, for opening or closing them. The first and the second connecting member are connected at an end to the first and the second opening, respectively, and at another end to an external water-replenishing and an external gas-removing apparatus, respectively, via a pipe each. With these arrangements, cooling fluid can be replenished into and surplus gas can be removed from a water cooling device without the need of disassembling or reworking the water cooling device.

Claims

1. A water-replenishing and gas-removing structure for water cooling device, comprising:

a flow-guiding main body having at least an inlet, an outlet, a water-receiving space, a first opening and a second opening; and

the inlet, the outlet, the first opening and the second opening being communicable with the water-receiving space;

a first valve member being arranged in the water-receiving space corresponding to the first opening for opening or closing the first opening;

a second valve member being arranged in the water-receiving space corresponding to the second opening for opening or closing the second opening;

a first connecting member being correspondingly connected to the first opening; and

a second connecting member being correspondingly connected to the second opening.

2. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the first connecting member has a first axial bore axially extended through the first connecting member, and a first radial connecting slot radially extended through the first connecting member and formed on an end of the first connecting member that is to be connected to the first opening;

and the first axial bore and the first radial connecting slot being communicable with each other.

3. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the second connecting member has a second axial bore axially extended through the second connecting member, and a second radial connecting slot radially extended through the second connecting member and formed on an end of the second connecting member that is to be connected to the second opening;

and the second axial bore and the second radial connecting slot being communicable with each other.

4. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the first valve member is composed of a first body, a first elastic element and a first valve seat;

the first valve body including a first valve stem, which is extended from one side of the first valve body for movably inserting into the first valve seat;

the first elastic element being fitted around the first valve stem with two ends of the first elastic element separately pressed against outer peripheral areas of the first valve body and the first valve seat.

5. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the second valve member is composed of a second body, a second elastic element and a second valve seat;

the second valve body including a second valve stem, which is extended from one side of the second valve body for movably inserting into the second valve seat;

the second elastic element being fitted around the second valve stem with two ends of the second elastic element separately pressed against outer peripheral areas of the second valve body and the second valve seat.

6. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the first and the second connecting member are connected to the first and the second opening, respectively, in a manner selected from the group consisting of screwing, tight-fitting and snap-fitting.

7. The water-replenishing and gas-removing structure as claimed in claim 6, wherein the first and the second connecting member have male threads externally provided at the end to be connected to the first and the second opening, respectively;

and the first and the second opening have female threads provided therein.

8. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the first connecting member is connected at another end, which is located opposite to the first opening, to a first pipe, and a cooling fluid being supplied via the first pipe and the first connecting member into the water-receiving space of the flow-guiding main body;

and wherein the second connecting member is connected at another end, which is located opposite to the second opening, to a second pipe, and surplus gas and surplus cooling fluid in the water-receiving space being guided out of the flow-guiding main body via the second connecting member and the second pipe.

9. The water-replenishing and gas-removing structure as claimed in claim 8, wherein the water-receiving space of the flow-guiding main body is internally provided with a first chamber, a second chamber, a third chamber, a heat-exchange chamber, and a communicating opening;

the inlet communicating with the first chamber, and the third chamber communicating with the heat-exchange chamber via the communicating opening.

10. The water-replenishing and gas-removing structure as claimed in claim 9, further comprising a first pump having a first inlet and a first outlet, and a second pump having a second inlet and a second outlet;

the first inlet communicating with the first chamber;

the second chamber communicating with the first outlet and the second inlet; and

the third chamber communicating with the second outlet.

11. The water-replenishing and gas-removing structure as claimed in claim 9, wherein the first opening communicates with the second chamber and the first valve member is correspondingly arranged in the second chamber;

and the second opening communicates with the third chamber and the second valve member is correspondingly arranged in the third chamber.

12. The water-replenishing and gas-removing structure as claimed in claim 1, wherein the inlet and the outlet of the flow-guiding main body are connected to a pump, and are further connected to a water-cooling radiator via a third pipe and a fourth pipe, respectively;

the pump driving a cooling fluid to circulate through the flow-guiding main body and the water-cooling radiator, and the water-cooling radiator being used to cool the cooling fluid that has absorbed heat.
