Description

Technical Field

[0001] The utility model relates to a double-CPU heat exchanger with a flow-dividing function. Background Art

[0002] Today's computer servers often use a dual-CPU design, and existing dual-CPU water-cooled radiators generally use a liquid-cooling head series structure to solve the dual-CPU heat dissipation problem. The disadvantage of this structure is that when cold water flows to the next CPU heat dissipation base after heat exchange through the previous CPU heat dissipation base, the temperature of the next heat dissipation base will be higher than that of the previous heat dissipation base. Therefore, the use of a liquid-cooling head series structure cannot solve the problem of large temperature differences when the dual CPUs are working, so that the performance of the CPU corresponding to the heat dissipation base with a higher temperature will be affected by the high temperature, resulting in a decrease in its computing power, thereby affecting the normal performance of the overall performance of the computer server. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a dual-CPU heat exchanger with a flow splitting function.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: the dual-CPU heat exchanger with a flow splitting function comprises a first liquid cooling head, a second liquid cooling head, a first pipeline, a second pipeline, a third pipeline and a fourth pipeline, and the first liquid cooling head is connected and installed with the second liquid cooling head through the second pipeline and the third pipeline;

The fourth channel is connected to the second heat exchange chamber, one end of the sixth channel is connected to the fifth channel, and the other end of the sixth channel is connected to the second heat exchange chamber.

[0007] By adopting the above-mentioned technical scheme, after the cold water enters the first liquid cooling head through the first pipe, the first liquid cooling head can divert the cold water entering therein, and part of the diverted cold water directly enters the second liquid cooling head through the second pipe to supply cold water to the second liquid cooling head, while the other part of the diverted cold water is transported through the internal channel of the first liquid cooling head and is transported into the second liquid cooling head through the third pipe after absorbing heat and heating, and is merged with the cold water after absorbing heat and heating inside the second liquid cooling head for discharge and collection.

[0008] In another embodiment, after the cold water enters the second liquid cooling head through the fourth pipe, the second liquid cooling head can divert the cold water entering therein, and part of the diverted cold water directly enters the first liquid cooling head through the third pipe to supply cold water to the first liquid cooling head, while the other part of the diverted cold water is transported through the internal channel of the second liquid cooling head and absorbs heat and rises in temperature, and then is transported into the first liquid cooling head through the second pipe, and converges with the cold water that has absorbed heat and risen in temperature inside the first liquid cooling head to be discharged and collected.

[0009] Preferably, a first interface and a second interface are respectively provided at two ends of the first channel, and a third interface is provided at the third channel.

[0010] Preferably, the fourth channel is provided with a fourth interface, and the fifth channel has a fifth interface and a sixth interface at both ends thereof.

[0011] Preferably, one end of the second pipeline is connected and installed with the second interface, and the other end of the second pipeline is connected and installed with the fourth interface.

[0012] Preferably, the first pipeline is connected and installed with the first interface.

[0013] By adopting the above technical solution, the first pipe is connected and installed with the first channel in the first liquid cooling head through the first interface, the first channel in the first liquid cooling head is connected and installed with the second pipe through the second interface, and the second pipe is connected and installed with the fourth channel in the second liquid cooling head through the fourth interface, so that water can flow along the first channel through the second pipe to the fourth channel, or water can flow from the fourth channel through the second pipe to the first channel, that is, water can be transported in both directions between the first channel, the second pipe and the fourth channel.

[0014] Preferably, one end of the third pipeline is connected and installed with the third interface, and the other end of the third pipeline is connected and installed with the fifth interface.

[0015] By adopting the above technical solution, the third channel in the first liquid cooling head is connected and installed with the third pipe through the third interface, and the third pipe is connected and installed with the fifth channel in the second liquid cooling head through the fifth interface, so that water can flow along the third channel through the third pipe to the fifth channel, or water can flow from the fifth channel through the third pipe to the third channel, that is, water can be transported in both directions between the third channel, the third pipe and the fifth channel.

[0016] Preferably, the fourth pipeline is connected and installed with the sixth interface.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: by designing the internal structures of the first liquid cooling head and the second liquid cooling head respectively, and by designing the connection relationship between the first liquid cooling head and the second liquid cooling head, it is possible to adopt a method of connecting the cold water passage and the hot water passage in parallel, and the cold water can be diverted and supplied through the same passage, and the hot water can be collected and recycled through the same passage, so that the heat dissipation of the two CPUs is more uniform, and there will no longer be a large temperature difference when the dual CPUs are working, so that the working temperature of each CPU can maintain a close heat dissipation effect. At the same time, it also effectively reduces the use of external three-way diverters and pipelines to reduce the risk of water leakage, which improves product reliability while reducing production costs. In addition, it also avoids the problem that the current dual-CPU water-cooled radiator adopts a structure of liquid cooling heads in series and cannot solve the problem that the computing power is reduced due to the large temperature difference when the dual CPUs are working and the overall performance of the computer server is affected.

[0041] In one embodiment, the fourth pipe 6 is connected and installed with the sixth interface 27 .

[0042] In one embodiment, the working process of the dual-CPU heat exchanger with a diversion function is as follows: the first channel 11 and the second channel 12 are connected and set, the first channel 11 is connected and installed with the second pipe 4 through the second interface 16, and cold water is transported and supplied through the first pipe 3. After the cold water enters the first liquid cooling head 1 from the first pipe 3, it is diverted through the first channel 11, wherein part of the cold water is diverted from the first channel 11 directly through the second pipe 4 into the second liquid cooling head 2, and another part of the cold water is diverted from the first channel 11 through the second channel 12 into the first heat exchange chamber 14, so as to supply cold water to the first heat exchange chamber 14; due to the dual-CPU heat exchange Two CPUs are respectively installed on the device, and the heat generated by the first CPU will be transferred to the first liquid cooling head 1, and the heat of the first liquid cooling head 1 is transferred to the cold water in the first heat exchange chamber 14 to achieve the cooling of the first CPU; since the third pipe 5 is connected and installed with the second liquid cooling head 2, one end of the third pipe 5 is connected and installed with the third channel 13 through the third interface 17, and the other end of the third pipe 5 is connected with the fifth channel 22 in the second liquid cooling head 2 through the fifth interface 26, the cold water in the first heat exchange chamber 14 is discharged along the third channel 13 after absorbing heat and heating up, and is transported to the fifth channel 22 in the second liquid cooling head 2 through the third pipe 5.
