Abstract

The present invention discloses a water cooling system for a computer, which includes a radiator, a cooling block in fluid communication with the radiator, and a liquid storage tank in fluid communication with the radiator and the cooling block. The radiator, the cooling block and the liquid storage tank are of an integrated structure. The water cooling system of the invention has an integrated structure which does not require user to assemble the components, thereby avoiding incidents such as liquid leakage. The water cooling system is provided with the liquid storage tank that is at least partially exposed outside a water cooling case, thereby increasing the amount of a cooling liquid, improving the heat dissipating efficiency, enabling a user to easily observe the amount of the cooling liquid, and improving the appearance of the water cooling case.

Claims

1. A water cooling system for a computer, comprising:

a radiator;

a cooling block in fluid communication with the radiator; and

a liquid storage tank in fluid communication with the radiator and the cooling block, wherein

the radiator, the cooling block and the liquid storage tank are of an integrated structure, and

the radiator comprises a first passage and a second passage isolated from each other, wherein the first passage is in fluid communication with a water outlet of the cooling block and a water inlet of the liquid storage tank, and the second passage is in fluid communication with a water outlet of the liquid storage tank and a water inlet of the cooling block, such that during the operation of the computer, the cooling liquid firstly enters the second passage of the radiator in which the cooling liquid is cooled to release a part of heat, and then the cooling liquid enters the first passage in which the cooling liquid is cooled again.

2. The water cooling system for a computer according to claim 1, wherein the liquid storage tank is provided with a water injection port.

3. The water cooling system for a computer according to claim 1, further comprising a water pump which is fixed on the cooling block.

4. The water cooling system for a computer according to claim 1, further comprising a water pump which is fixed on the liquid storage tank.

5. The water cooling system for a computer according to claim 1, further comprising a water pump which is fixed on the radiator.

6. A water cooling case for a computer, wherein a water cooling system is installed on the water cooling case, the water cooling system comprising:

a radiator fixed in the water cooling case;

a cooling block in fluid communication with the radiator; and

a liquid storage tank in fluid communication with the radiator and the cooling block, wherein

the radiator, the cooling block and the liquid storage tank are of an integrated structure, and

the radiator comprises a first passage and a second passage isolated from each other, wherein the first passage is in fluid communication with a water outlet of the cooling block and a water inlet of the liquid storage tank, and the second passage is in fluid communication with a water outlet of the liquid storage tank and a water inlet of the cooling block, such that during the operation of the computer, the cooling liquid firstly enters the second passage of the radiator in which the cooling liquid is cooled to release a part of heat, and then the cooling liquid enters the first passage in which the cooling liquid is cooled again.

7. The water cooling case for a computer according to claim 6, wherein the liquid storage tank is at least partially exposed outside the water cooling case.

8. The water cooling case for a computer according to claim 7, wherein the liquid storage tank is provided thereon with a water injection port which is exposed outside the water cooling case.

9. An integrated water cooling system for a computer case, comprising:

a radiator having a first passage and a second passage, the second passage separated from the first passage;

a cooling block configured for fluid communication with the radiator; and

a liquid storage tank configured for fluid communication with the radiator and the cooling block, wherein

the first and second passage are configured for fluid communication with the cooling block and the liquid storage tank, and

operation of a computer housed within the computer case causes cooling liquid to enter the second passage of the radiator where the cooling liquid is cooled to release heat, and whereupon cooling liquid enters the first passage of the radiator for further cooling.

10. The integrated water cooling system of claim 9, wherein the cooling block includes at least a water inlet and a water outlet, and the liquid storage tank includes at least a water inlet and a water outlet.

11. The integrated water cooling system of claim 10, wherein the first passage is configured for fluid communication with the water outlet of the cooling block and the water inlet of the liquid storage tank, and the second passage is configured for fluid communication with the water outlet of the liquid storage tank and the water inlet of the cooling block.

a second pipe;

a third pipe; and

a fourth pipe, wherein

the first passage is configured for fluid communication with a water outlet of the cooling block via the fourth pipe and configured for fluid communication with a water inlet of the liquid storage tank via the first pipe, and

the second passage is configured for fluid communication with a water outlet of the liquid storage tank via the second pipe and configured for fluid communication with a water inlet of the cooling block via the third pipe.

13. The integrated water cooling system of claim 9, wherein the liquid storage tank further comprises a water injection port.

14. The integrated water cooling system of claim 12, wherein during operation of the computer, the heat generated by the computer is transferred to the cooling liquid in the cooling block, and the cooling liquid enters the second passage of the radiator via the fourth pipe where the cooling liquid is cooled to release heat.

15. The integrated water cooling system of claim 14, wherein the cooling liquid enters the liquid storage tank via the first pipe for heat exchange with the cooling liquid in the liquid storage tank, whereupon the cooling liquid enters the first passage via the second pipe in which the cooling liquid is further cooled.

16. The integrated water cooling system of claim 15, wherein the cooling liquid returns to the cooling block via the third pipe.

17. The integrated water cooling system of claim 9, wherein the case includes an opening for a portion of the liquid storage tank to extend through and remain exposed outside the case.
