Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, and particularly to a double-channel liquid cooling plate. Background Art

[0002] As an efficient heat dissipation method, the development of liquid cooling technology can be traced back to the 1960s. With the expansion of the scale of data centers and the increase in the power of a single rack, the heat dissipation problem has gradually become a bottleneck restricting its development. In the prior art, in traditional liquid cooling plates, due to the overly long flow channels, the pressure of the cooling liquid increases with the length during the flow inside the flow channels, reducing the flow rate of the cooling liquid. At the same time, due to the overly long flow channels, the heat conduction efficiency will decrease during the transmission in the latter section of the flow channels, which greatly affects the working efficiency of the liquid cooling plate. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a double-channel liquid cooling plate.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows: The utility model mainly relates to a double-channel liquid cooling plate, which includes a main board body. At least one group of double-channel systems are arranged inside the main board body. The double-channel system includes a first flow channel, a second flow channel, a first water inlet end, a second water inlet end, and a water outlet end. The first water inlet end and the second water inlet end are arranged on both sides of the water outlet end. The first water inlet end is communicated with the water outlet end through the first flow channel, and the second water inlet end is communicated with the water outlet end through the second flow channel.

[0005] Preferably, the first water inlet end, the second water inlet end, and the water outlet end are arranged on the same side of the main board body.

[0006] Preferably, the first flow channel includes a plurality of first pipe body parts and a first bending part. The first pipe body parts are arranged along the length direction of the main board body. Among them, the plurality of first pipe body parts are spaced apart on the main board body, and adjacent two first pipe body parts are connected through the first bending part.

[0007] Preferably, the second flow channel includes a plurality of second pipe body parts and a second bending part. The second pipe body parts are arranged along the length direction of the main board body. Among them, the plurality of second pipe body parts are spaced apart on the main board body, and adjacent two second pipe body parts are connected through the second bending part.

[0008] Preferably, in the double-channel system, the first flow channel and the second flow channel are symmetrically distributed, and the lengths of the first flow channel and the second flow channel are the same.

[0009] Preferably, the double-channel liquid cooling plate further includes a water-cooled side plate, and the water-cooled side plate is installed on one side of the main board body.

[0010] Preferably, the water-cooled side plate is provided with a water supply pipe and a water outlet pipe. The water supply pipe is provided with a plurality of water inlet interfaces, and the water outlet pipe is provided with a plurality of water outlet interfaces. The water inlet interfaces are respectively connected to the first water inlet end and the second water inlet end, and the water outlet interfaces are respectively connected to the water outlet end.

[0011] The beneficial effects of the present utility model are as follows: The present utility model relates to a double-channel liquid cooling plate. In the present utility model, a double-channel system is designed on the main board body. In the double-channel system, the first flow channel and the second flow channel are symmetrically and evenly distributed on the main board body, reducing the path length of the flow channel while ensuring the integrity of the temperature reduction effect of the liquid cooling plate.

[0012] Since the lengths of the first flow channel and the second flow channel are reduced, the pressure of the cooling liquid flowing inside the flow channel is also reduced accordingly. When working, there is no need to adopt a high-power water supply system to maintain the flow of the cooling liquid, thereby reducing energy consumption.

[0013] After the cooling liquid flows into the first flow channel and the second flow channel respectively, the first flow channel and the second flow channel work simultaneously. The cooling liquid can quickly pass through the first flow channel and the second flow channel. As the pressure decreases, while the flow rate increases, it also ensures the uniformity of the overall temperature of the liquid cooling plate, improves the temperature reduction effect, and avoids the problem of reduced heat conduction efficiency during the transmission of the latter section of the flow channel due to the excessive length of the flow channel.

[0021] Please refer to Figures 1-5 As shown, the present utility model relates to a double-channel liquid cooling plate, which includes a main board body 4, and at least one group of double-channel systems 1 are arranged in the main board body 4. In this embodiment, two groups of double-channel systems 1 are arranged in the main board body 4, as Figure 2 . Figure 4 is one of the double-channel systems 1. The double-channel system 1 includes a first flow channel 11, a second flow channel 12, a first water inlet end 13, a second water inlet end 14 and a water outlet end 15. The first water inlet end 13, the second water inlet end 14 and the water outlet end 15 are arranged on the same side of the main board body 4. The first water inlet end 13 and the second water inlet end 14 are arranged on both sides of the water outlet end 15. The first water inlet end 13 is communicated with the water outlet end 15 through the first flow channel 11, and the second water inlet end 14 is communicated with the water outlet end 15 through the second flow channel 12. The first flow channel 11 and the second flow channel 12 share a water outlet end 15, and the water inlet directions are the same. The first water inlet end 13 and the second water inlet end 14 enter water in the same direction at the same time. The flowing water paths of the first flow channel 11 and the second flow channel 12 are symmetrically arranged with the water outlet end 15 as the central axis. In addition, the first flow channel 11 and the second flow channel 12 can also adopt two independent water outlet ends 15, and the first water inlet end 13 and the second water inlet end 14 enter water in different directions at the same time.

[0022] Further, in this embodiment, the first flow channel 11 is arranged in a serpentine distribution on the main board body 4. The first flow channel 11 includes a plurality of first pipe body parts 111 and first bent parts 112. The first pipe body parts 111 extend along the length direction of the main board body 4. Among them, a plurality of the first pipe body parts 111 are spaced apart on the main board body 4, and adjacent two first pipe body parts 111 are connected by the first bent parts 112, so as to form the serpentine-distributed first flow channel 11.

[0023] In this embodiment, the second flow channel 12 is arranged in a serpentine distribution on the main board body 4. The second flow channel 12 is located on one side beside the first flow channel 11. The second flow channel 12 includes a plurality of second pipe body parts 121 and second bent parts 122. The second pipe body parts 121 extend along the length direction of the main board body 4. Among them, a plurality of the second pipe body parts 121 are spaced apart on the main board body 4, and adjacent two second pipe body parts 121 are connected by the second bent parts 122, so as to form the serpentine-distributed second flow channel 12.

[0024] In this embodiment, in order to ensure the stability of the double-channel system 1, the lengths of the first flow channel 11 and the second flow channel 12 are the same. The same length design can reduce the problem of uneven flow distribution caused by the length difference of the flow channels, thereby reducing the instability and failure rate of the system.

[0025] The double-channel liquid cooling plate further includes a water-cooled side plate 2, and the water-cooled side plate 2 is installed on one side of the main board body 4. The water-cooled side plate 2 is provided with a water supply pipe 21 and a water outlet pipe 22. The water supply pipe 21 is provided with a plurality of water inlet interfaces 211, and the water outlet pipe 22 is provided with a plurality of water outlet interfaces 221. When the water-cooled side plate 2 is installed on the main board body 4, the water inlet interfaces 211 are respectively communicated with the first water inlet end 13 and the second water inlet end 14, and the water outlet interfaces 221 are respectively communicated with the water outlet end 15. The water-cooled side plate 2 is arranged on the same side of the main board body 4, which is beneficial to reducing the pipes and connectors for connecting external devices, is applicable to occasions with limited space, and reduces the complexity and manufacturing cost of the system.

[0026] In the present utility model, the main board body 4 can also be designed into a double-layer structure. The double-layer structure includes an upper flow channel and a lower flow channel. The upper flow channel is arranged above the lower flow channel, and at least one set of double-channel systems 1 are respectively arranged on the upper flow channel and the lower flow channel. During operation, since the cooling liquid simultaneously enters the upper flow channel and the lower flow channel and can quickly take away heat, rapid cooling can be achieved, so that the temperature of the whole liquid cooling plate is uniform and stable, and a better cooling effect is realized.

[0027] The following is the working process of a double-channel liquid cooling plate of the present utility model: First, the cooling liquid 3 is input into the water supply pipe 21. The cooling liquid 3 simultaneously enters the first flow channel 11 and the second flow channel 12 through the water inlet interfaces 211 respectively. The cooling liquid 3 is pumped out from the water outlet pipe 22 through the water supply system, so that the cooling liquid 3 quickly passes through the first flow channel 11 and the second flow channel 12, and the first flow channel 11 and the second flow channel 12 are uniformly distributed on the main board body 4. Finally, the cooling liquid 3 flows from the first flow channel 11 and the second flow channel 12 to the water outlet pipe 22 uniformly from the water outlet end 15, so that the liquid cooling plate can effectively reduce the temperature of the electronic device.

[0028] The present utility model relates to a double-channel liquid cooling plate. In the present utility model, by designing a double-channel system 1 on the main board body 4, the first flow channel 11 and the second flow channel 12 in the double-channel system 1 are symmetrically and uniformly distributed on the main board body 4, which reduces the path length of the flow channel while ensuring the integrity of the cooling effect of the liquid cooling plate.

[0029] Since the lengths of the first flow channel 11 and the second flow channel 12 are reduced, the pressure of the cooling liquid 3 when flowing inside the flow channel is also reduced accordingly. During operation, there is no need to adopt a high-power water supply system to maintain the flow of the cooling liquid 3, so the energy consumption can be reduced.

[0030] After the cooling liquid 3 flows into the first flow channel 11 and the second flow channel 12 respectively, the first flow channel 11 and the second flow channel 12 work simultaneously. The cooling liquid 3 can quickly pass through the first flow channel 11 and the second flow channel 12. As the pressure decreases, while the flow rate increases, it also ensures the uniformity of the overall temperature of the liquid cooling plate, improves the cooling effect, and avoids the problem of reduced heat conduction efficiency in the later stage of the flow channel transmission due to the too long flow channel.

[0031] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
