Description

Technical Field

[0001] The utility model relates to the technical field of cooling systems, in particular to a water cooling system for a CPU of a server. Background Art

[0002] With the rapid development of Internet technology and communication technology, especially the advent of 5G technology, data centers are being used more and more widely. The CPU of the server in the data center will generate a lot of heat when running efficiently. If the heat cannot be dissipated in time, the performance and operation of the server will inevitably be affected, and the possibility of data damage or loss will also be greatly increased, and it may even lead to the paralysis of the entire data center. Therefore, it is particularly important to quickly discharge the heat generated by the server's CPU.

[0003] In view of this, in order to solve the cooling problem of the server, authorization announcement number CN218848688U discloses a CPU water cooling system for a server, which specifically discloses a water cooling head, a radiator, and at least two groups of water pumps, wherein the water outlet of one of the water pumps is connected with the water outlet of the other water pump to form a pump body water outlet, and the water inlet of one of the water pumps is connected with the water inlet of the other water pump to form a pump body water inlet, and the pump body water outlet, the water cooling head, the radiator, and the pump body water inlet are connected in sequence.

[0004] The CPU water cooling system of the above-mentioned server uses two water pumps arranged in parallel on the water pipe, so that when one of the water pumps is damaged and needs to be repaired or replaced, the other water pump can provide heat dissipation for the system alone, thereby reducing the situation of system downtime, reducing the loss caused by water pump damage, and improving the protection of the CPU and the server. However, the CPU water cooling system of the above-mentioned server still has some disadvantages, for example: although the two water pumps are arranged in parallel on a water pipe. However, when the two water pumps are working at the same time, due to the crowding of the coolant, the flow rate of the water outlet of the water pump at the rear side will be relatively large, that is, the outlet pressure of the water pump will be relatively large per unit time. If the water pump is used for a long time, the probability of the water pump failure will be increased to a certain extent, that is, the service life of the water pump may be reduced.

[0042] Embodiment 2:

[0043] like Figure 2-Figure 7 As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, the CPU water cooling system of the server further includes a first connector 10 and a second connector 11.

In addition, it is not necessary to set other three-way joints and the like at the remaining positions of the water inlet pipe 4 and the water outlet pipe 5. Because the two first cooling liquid chambers 101 and the two second cooling liquid chambers 111 are directly connected to the first liquid cooling head 2 and the second liquid cooling head 3 respectively, that is, they do not need to be connected through water pipes, which can reduce the use of water pipes to a certain extent.

In this way, the two three-way joints and the two adapter elbows can form an integrated structure with the first liquid cooling head 2 and the second liquid cooling head 3 respectively and ensure the flow circulation of the coolant. In addition, other three-way joints and the water inlet pipe 4 and the water outlet pipe 5 do not need to be provided at other positions. Because the three-way joints and the adapter elbows are directly connected to the first liquid cooling head 2 and the second liquid cooling head 3, that is, there is no need to communicate through water pipes, which will also reduce the use of water pipes to a certain extent. Finally, the above design can make the structure of the entire system simple and beautiful.

[0058] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
