Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

Nowadays, with the technical development and iterative upgrade of the super computing server, the overall computing power of the data center is greatly improved, and in order to ensure the running stability and the service life of the server, heat dissipation treatment is required to enable the server to work in an optimal temperature range, so that the heat dissipation requirement of the data center is also improved. Common heat dissipation modes include an air cooling heat dissipation mode and a liquid cooling heat dissipation mode, wherein the liquid cooling heat dissipation mode gradually becomes a main stream heat dissipation mode of the server due to the advantages of better heat dissipation effect, smaller noise and the like.

However, the arrangement form of the U-shaped connecting pipe generally comprises an arrangement under the frame plate and a top hanging arrangement, when the arrangement form under the frame plate is adopted, the overhead frame plate is required to be arranged above the ground of a machine room, the U-shaped connecting pipe is buried in the space between the frame plate and the ground, in this case, if liquid leakage occurs at a certain connecting position, a technician needs to dismantle the frame plate to contact the valve body, the operation and maintenance procedures are complicated, and because the number of the valve bodies arranged on the U-shaped connecting pipe is very large, the technician also hardly finds the valve body corresponding to the fault point, and the operation and maintenance difficulty is high. When adopting top to hang formula to arrange, U type connecting pipe is located the top of liquid cooling rack, and is connected with the ceiling of computer lab through the furred ceiling, can set up the valve body that quantity is more on the U type connecting pipe, namely the valve body is arranged in a relatively great region (the broken line frame region in the drawing), this makes when having a plurality of weeping positions, and the maintenance personnel is difficult to close the valve body that a plurality of weeping positions correspond simultaneously, and whole cooling system's overall operation maintenance inefficiency, operation maintenance cost is too high.

The first water collector 4 comprises a first liquid outlet pipe 41, a plurality of second valve bodies 42 and a plurality of second branch pipes 43, wherein two ends of the first liquid outlet pipe 41 are communicated with the liquid return pipe 5, the plurality of second valve bodies 42 are arranged on the first liquid outlet pipe 41 at intervals, one end of each second branch pipe 43 is located between two adjacent second valve bodies 42 and communicated with the first liquid outlet pipe 41, and the other end of each second branch pipe 43 is communicated with the liquid outlet manifold 12.

In this way, by adopting the liquid cooling heat dissipation system provided by the embodiment of the disclosure, the valve body for controlling each liquid cooling cabinet 1 to be connected to or separated from the whole liquid cooling heat dissipation system is integrated in the first water separator 2 or the first water collector 4, when liquid leakage occurs in the liquid inlet manifold 11, the liquid outlet manifold 12, the passage between the liquid inlet manifold 11 and the liquid supply pipe 3 and/or the passage between the liquid outlet manifold 12 and the liquid return pipe 5 of any liquid cooling cabinet 1, only the valve body in the first water separator 2 and/or the first water collector 4 is required to be directly closed, so that the corresponding liquid cooling cabinet 1 is controlled to be separated from the whole liquid cooling heat dissipation system, the liquid leakage is salvaged, the operation and maintenance efficiency of the liquid cooling heat dissipation system is greatly improved, and the operation and maintenance difficulty of the liquid cooling heat dissipation system is reduced.

In implementation, the server monomer located in the accommodating groove 101 generates heat during operation, and the temperature of the cooling liquid is raised after heat exchange with the server monomer, so that liquid cooling heat dissipation of the server is realized with part of heat.

Referring to fig. 11, the liquid-cooled cabinet 1 has a liquid inlet 102 and a liquid outlet 103, wherein the liquid inlet 102 is connected to the liquid inlet manifold 11 and the liquid outlet 103 is connected to the liquid outlet manifold 12.

Therefore, the quick connection of the liquid supply pipe 3 and the liquid inlet 102 can be realized by utilizing the quick connection plug, the quick connection of the liquid outlet 103 and the liquid return pipe 5 can be realized, and the assembly efficiency of the liquid cooling system is improved.

The shapes of the liquid inlet 102 and the liquid outlet 103 may be the same or different, for example, the shapes of the liquid inlet 102 and the liquid outlet 103 are all circular, and of course, the shapes of the liquid inlet 102 and the liquid outlet 103 may also be different, for example, the shape of the liquid inlet 102 is circular, and the shape of the liquid outlet 103 is rectangular, which is not limited in the embodiment of the disclosure.

2. Liquid supply pipe 3 and liquid return pipe 5

The liquid supply pipe 3 is a component for transferring low-temperature cooling liquid to the liquid cooling cabinet 1 in the server liquid cooling heat dissipation system, and the liquid return pipe 5 is a component for receiving the warmed cooling liquid flowing out of the liquid cooling cabinet 1 in the server liquid cooling heat dissipation system.

In some possible embodiments, both the supply pipe 3 and the return pipe 5 are loop pipes.

At this time, if any one of the valve bodies arranged on the liquid supply pipe 3 fails, the first water separator 2 adjacent to the failed valve body cannot be connected to the server liquid cooling heat dissipation system, or if any one of the valve bodies arranged on the liquid return pipe 5 fails, the first water collector 4 adjacent to the failed valve body cannot be connected to the server liquid cooling heat dissipation system, and accordingly, the liquid cooling cabinet communicated with the first water separator 2 and the first water collector 4 cannot be effectively cooled.

In one example, the liquid supply pipe 3 and the liquid return pipe 5 are arranged in a loop double-valve mode, and referring to fig. 2, in the case that the valve bodies located in the dashed line frames in fig. 2 are arranged on the liquid supply pipe 3 and the liquid return pipe 5, two valve bodies are arranged between two adjacent opening structures. At this time, if any one of the valve bodies arranged on the liquid supply pipe 3 fails, one of the first water separators 2 closest to the failed valve body cannot be connected to the server liquid cooling heat dissipation system, or if any one of the valve bodies arranged on the liquid return pipe 5 fails, one of the first water collectors 4 closest to the failed valve body cannot be connected to the server liquid cooling heat dissipation system, and accordingly, the liquid cooling cabinet which is communicated with the first water separator 2 and the first water collector 4 which cannot be connected to the liquid cooling heat dissipation system cannot be effectively cooled. The arrangement modes of the liquid supply pipe 3 and the liquid return pipe 5 are not limited in the embodiment of the disclosure, and a technician can set the liquid supply pipe and the liquid return pipe according to actual needs.

In practice, as shown in fig. 12, the liquid supply pipe 3 and the liquid return pipe 5 may be disposed on the first side of the liquid cooling system, that is, the liquid supply pipe 3 and the liquid return pipe 5 may be disposed on the outdoor side. Specifically, a plurality of liquid cooling cabinets 1 can all set up in the computer lab, and feed pipe 3 and return liquid pipe 5 can set up in the air conditioner room, and the inside many forced air cooling air conditioner 001 that are provided with of air conditioner room for cool down to the coolant liquid in feed pipe 3 and the return liquid pipe 5, and carry the heat outdoors.

3. First water separator 2

The first water separator 2 is a component in the server liquid cooling heat dissipation system for dividing the low-temperature cooling liquid in the liquid supply pipe 3 into a plurality of liquid cooling cabinets 1 and controlling any liquid cooling cabinet 1 to be connected to or separated from the whole server liquid cooling heat dissipation system.

As shown in fig. 3, the first water separator 2 includes a first liquid inlet pipe 21, a plurality of first valve bodies 22, a plurality of first branch pipes 23, and a first tank 201. The first liquid inlet pipe 21 is at least partially located in the first box 201, one end of the plurality of first branch pipes 23 is located in the first box 201 and is communicated with a portion of the first liquid inlet pipe 21 located inside the first box 201, and the other end of the first branch pipe 23 extends out of the first box 201 and is communicated with the liquid inlet manifold 11.

Illustratively, the tube diameter of the first inlet tube 21 may be one of DN125 and DN 150.

In implementation, the pipe diameter of the first liquid inlet pipe 21 may be selected according to the heat generating power of the server monomer in the liquid cooling cabinet 1, or the pipe diameter of the first liquid inlet pipe 21 may be selected according to the type of the server monomer in the liquid cooling cabinet 1. For example, when the type of the server monomer is CPU, the pipe diameter of the first liquid inlet pipe 21 may be set to DN125 because the heat generation power of the server monomer is low, and when the type of the server monomer is GPU, the pipe diameter of the first liquid inlet pipe 21 may be set to DN125 because the heat generation power of the server monomer is relatively high.

Illustratively, the pipe diameter of the first branch pipe 23 may be one of DN25, DN32, DN40, and DN 50.

The first liquid inlet pipe 21 and the first branch pipe 23 may also have various other reasonable pipe diameters, and a technician may set up the liquid inlet pipe according to actual needs, which is not limited in the embodiment of the present disclosure.

In one example, in the server liquid cooling heat dissipation system, one first water separator 2 may correspondingly manage 10 liquid cooling cabinets, the pipe diameter of the first liquid inlet pipe 21 is DN125, the first water separator 2 includes 10 first branch pipes 23, and the pipe diameter of the first branch pipes 23 is DN25.

In another example, in the server liquid cooling heat dissipation system, one first water separator 2 may correspondingly manage 10 liquid cooling cabinets, the pipe diameter of the first liquid inlet pipe 21 is DN150, the first water separator 2 includes 10 first branch pipes 23, and the pipe diameter of the first branch pipe 23 is DN50.

As shown in fig. 2, both ends of the first liquid inlet pipe 21 are communicated with the liquid supply pipe 3.

In one example, the first liquid inlet pipe 21 may be a U-shaped pipe structure, the liquid supply pipe 3 is a ring pipe, and two ends of the first liquid inlet pipe 21 are respectively communicated with two opening structures on the liquid supply pipe 3.

As shown in fig. 2 and 3, a plurality of first valve bodies 22 are arranged at intervals on the first liquid inlet pipe 21, one end of the first branch pipe 23 is located between two adjacent first valve bodies 22 and is communicated with the first liquid inlet pipe 21, and the other end of the first branch pipe 23 is communicated with the liquid inlet manifold 11.

In this way, for any one of the first branch pipes 23, after the two adjacent corresponding first valve bodies 22 are adjusted to be in a closed state, the corresponding liquid cooling cabinet 1 can be separated from the liquid cooling system, and because the first liquid inlet pipe 21 is of a U-shaped pipe-shaped installation structure, the liquid supply pipe 3 is a loop pipe, other first branch pipes 23 can still form a loop through the first liquid inlet pipe 21, the liquid cooling cabinet 1 corresponding to the other first branch pipes 23 can still normally run for heat dissipation, and the influence of a fault point is avoided.

In the implementation, when the liquid leakage occurs at the connection position between any one of the liquid inlet manifolds 11 and the first branch pipe 23, or the liquid leakage occurs at the connection position between any one of the first branch pipes 23 and the liquid supply pipe 3, the corresponding two adjacent first valve bodies 22 can be closed, so that the liquid cooling cabinet 1 corresponding to the liquid leakage position separates the whole server liquid cooling heat dissipation system, and then the liquid leakage position is maintained.

The power technicians of the first water separator 2 and the first water collector 4 can be adjusted according to actual needs, and the embodiment of the disclosure is not limited to this.

4. First water collector 4

The first water collector 4 is a component for receiving and converging the warmed coolant flowing out of the liquid cooling cabinet 1 in the server liquid cooling heat dissipation system, and making the coolant flow to the liquid supply pipe 3.

As shown in fig. 4, the first water collector 4 includes a first liquid outlet pipe 41, a plurality of second valve bodies 42, a plurality of second branch pipes 43, and a second tank 401. The first liquid outlet pipe 41 is at least partially located in the second box 401, one end of the plurality of second branch pipes 43 is located in the second box 401 and is communicated with a portion of the first liquid outlet pipe 41 located inside the second box 401, and the other end of the second branch pipe 43 extends out of the second box 401 and is communicated with the liquid outlet manifold 12.

Illustratively, the pipe diameter of the first liquid outlet pipe 41 may be the same as the pipe diameter of the first liquid inlet pipe 21, that is, the pipe diameter of the first liquid outlet pipe 41 may be one of DN125 and DN150, in which case the pipe diameter of the first liquid inlet pipe 21 is DN125, the pipe diameter of the first liquid outlet pipe 41 is DN125, and in which case the pipe diameter of the first liquid inlet pipe 21 is DN150, the pipe diameter of the first liquid outlet pipe 41 is DN150.

Illustratively, the pipe diameter of the second branch pipe 43 is the same as the pipe diameter of the first branch pipe 23, and the pipe diameter of the second branch pipe 43 may be one of DN25, DN32, DN40, and DN 50.

Like this, the pipe diameter of each pipeline in the first water knockout drum 2 is the same with the pipe diameter of corresponding pipeline in the first water collector 4, can guarantee the continuity that the coolant liquid flows, promotes cooling efficiency.

In one example, in the server liquid cooling heat dissipation system, one first water collector 4 may correspondingly manage 10 liquid cooling cabinets, the pipe diameter of the first liquid outlet pipe 41 is DN125, the first water collector 4 includes 10 second branch pipes 43, and the pipe diameter of the second branch pipes 43 is DN25.

In another example, in the server liquid cooling heat dissipation system, one first water collector 4 may correspondingly manage 10 liquid cooling cabinets, the pipe diameter of the first liquid outlet pipe 41 is DN150, the first water collector 4 includes 10 second branch pipes 43, and the pipe diameter of the second branch pipes 43 is DN50.

As shown in fig. 2, both ends of the first liquid outlet pipe 41 are communicated with the liquid return pipe 5.

In this way, for any one of the second branch pipes 43, after the two corresponding adjacent second valve bodies 42 are adjusted to be in the closed state, the corresponding liquid cooling cabinet 1 can be separated from the liquid cooling system, and because the first liquid outlet pipe 41 is of a U-shaped pipe-shaped installation structure, the liquid return pipe 5 is a loop pipe, the other second branch pipes 43 can still form a loop through the first liquid outlet pipe 41, the liquid cooling cabinet 1 corresponding to the other second branch pipes 43 can still normally run for heat dissipation, and the heat dissipation function is not influenced by a fault point.

In implementation, when liquid leakage occurs at the connection position between any one of the liquid outlet manifolds 12 and the second branch pipe 43, or at the connection position between any one of the second branch pipe 43 and the liquid return pipe 5, the corresponding two adjacent second valve bodies 42 can be closed, so that the liquid cooling cabinet 1 corresponding to the liquid leakage position separates the whole server liquid cooling heat dissipation system, the liquid leakage position is ensured not to continuously occur, then the liquid leakage position is maintained, and further the maintenance efficiency is improved.

In some possible embodiments, the first water separator 2 further comprises a plurality of first three-way joints 25 and a plurality of first gas valves 26, and the first water collector 4 further comprises a plurality of second three-way joints 45 and a plurality of second gas valves 46.

Thus, by arranging the first air valve 26, air mixed in the cooling liquid flowing into the liquid cooling cabinet 1 can be removed, the cooling efficiency of the server is improved, and meanwhile, by arranging the second air valve 46, air mixed in the cooling liquid flowing into the liquid return pipe 5 can be removed for the cooling liquid flowing out of the liquid cooling cabinet 1, and the heat exchange efficiency of the cooling liquid after temperature rise is improved.

In one example, the first tee 25 is integrally formed with the first leg 23 and the second tee 45 is integrally formed with the second leg 43.

In this way, it is possible to improve the air tightness and the connection strength between the first three-way joint 25 and the first branch pipe 23, and to improve the air tightness and the connection strength between the second three-way joint 45 and the second branch pipe 43.
