Description

Technical Field

[0001] The present application relates to the field of heat dissipation technology, and in particular to a PCB board assembly, a water distributor, a liquid cooling module, a liquid cooling system and an electronic device. Background Art

[0002] Liquid cooling is a heat dissipation method with better heat dissipation efficiency than air cooling. The key component of liquid cooling is the liquid cooling plate, which is in contact with the heating element and has a flow channel inside. The heat dissipation principle of the liquid cooling plate is as follows: the cooling water enters from the water inlet of the flow channel of the liquid cooling plate, is heated by the heating element, flows out from the water outlet of the flow channel, and after cooling down outside, flows back into the flow channel through the water inlet. The above process is repeated continuously, and the heat of the heating element is continuously taken out.

[0003] In the related art, there is a liquid-cooled printed circuit board (PCB) assembly, which includes a PCB and a liquid cooling plate, and the heating element on the PCB is in contact with the liquid cooling plate. The liquid cooling plate is provided with two liquid cooling plugs respectively connected to the two ends of the flow channel, and correspondingly, the water distributor (connected to the external water tank) is provided with two liquid cooling sockets. During the insertion process of the liquid-cooled PCB assembly, while the electrical connector of the PCB is inserted into the PCB slot, the liquid cooling plug on the liquid cooling plate is also inserted into the liquid cooling socket of the water distributor, and the operation is synchronized, which is very convenient.

[0004] However, due to the limitation of manufacturing process, the position relationship between the electrical connector and the liquid cooling plug in the liquid cooling PCB assembly may not completely match the position relationship between the PCB slot and the liquid cooling socket. In this way, during the plugging process of the PCB assembly, the PCB and the liquid cooling plate may deviate, resulting in loose contact between the heating element and the liquid cooling plate, or even separation, which seriously affects the heat dissipation efficiency.

[0076] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0077] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0078] The present application embodiment provides a printed circuit board (PCB) component, such as Figure 1 As shown, the PCB board assembly includes a PCB board 11, a bracket 12, a liquid cooling plate 13, a water inlet plug 14 and a water outlet plug 15. The PCB board 11 is fixedly connected to the bracket 12. The liquid cooling plate 13 is fixedly connected to the PCB board 11, and the liquid cooling plate 13 is in contact with the heating element of the PCB board 11, and the liquid cooling plate 13 is flexibly connected to the bracket 12. The water inlet plug 14 and the water outlet plug 15 are both fixedly connected to the bracket 12, and the axial directions of the water inlet plug 14 and the water outlet plug 15 are parallel to the insertion direction of the PCB board 11.

[0079] The heating element on the PCB board 11 can be any element that can generate heat, and the embodiment of the present application does not specifically limit this. For example, the heating element on the PCB board 11 can be a graphics processing unit (GPU) chip, and the PCB board 11 provided in the embodiment of the present application can be called a GPU board or a GPU card.

[0080] The bracket 12 serves to fix the water inlet plug 14 , the water outlet plug 15 and the PCB board 11 .

[0081] The liquid cooling plate 13 is a plate-shaped member with cooling water flowing inside. In order to ensure high heat dissipation efficiency of the heating element, the liquid cooling plate 13 needs to be in close contact with the heating element of the PCB board 11. The liquid cooling plate 13 is flexibly connected to the bracket 12, so that the movement of the bracket 12 will not drive the liquid cooling plate 13 to move synchronously. In addition, the liquid cooling plate 13 is fixedly connected to the PCB board 11, so the relative position of the liquid cooling plate 13 and the phase position of the PCB board 11 are fixed, and the liquid cooling plate 13 can flexibly match the height of the heating element to achieve floating relative to the bracket 12. The liquid cooling plate 13 can also be called a cold plate.

[0082] The water inlet plug 14 and the water outlet plug 15 are used to dock with the water outlet socket 24 and the inlet socket 25 on the water distributor 2. The water inlet plug 14 and the water outlet plug 15 can be collectively referred to as liquid cooling plugs. The liquid cooling plug can be automatically blocked when it is pulled out from the liquid cooling socket to prevent the cooling water in the pipeline from flowing out of the liquid cooling plug. The specific implementation of the liquid cooling plug is not specifically limited in the embodiment of the present application. For example, the water inlet plug 14 and the water outlet plug 15 can adopt a blind plug connector (or blind plug liquid cooling plug).

[0083] In the solution shown in the embodiment of the present application, the liquid cooling plug (including the water inlet plug 14 and the water outlet plug 15) in the PCB assembly provided in the embodiment of the present application is fixed on the bracket 12. During the insertion of the PCB board assembly, if the positional relationship between the PCB board slot and the liquid cooling socket does not completely match the positional relationship between the electrical connector of the PCB board assembly and the liquid cooling plug, the PCB board slot and the liquid cooling socket will push the bracket 12 and the PCB board 11 to deviate by touching the electrical connector and the liquid cooling plug, so as to ensure that the PCB board assembly can be smoothly plugged into place.

[0084] However, since the bracket 12 in the PCB board assembly provided in the embodiment of the present application is flexibly connected to the liquid cooling plate 13, the bracket 12 cannot drive the liquid cooling plate 13 to deviate from the PCB board 11. In addition, the liquid cooling plate 13 is fixedly connected to the PCB board 11, so the heating element of the PCB board 11 is always in close contact with the liquid cooling plate 13, so that the heat dissipation efficiency of the PCB board assembly provided in the embodiment of the present application is higher.

[0085] The specific implementation method of the flexible connection between the liquid cooling plate 13 and the bracket 12 is not limited in the embodiment of the present application.

[0086] In one possible implementation, Figure 1 As shown, the water inlet plug 14 is flexibly connected to the water inlet interface 131 of the liquid cooling plate 13 through the water supply hose 16 , and the water outlet plug 15 is flexibly connected to the water outlet interface 132 of the liquid cooling plate 13 through the water return hose 17 .

[0087] That is, for the liquid cooling plate 13 and the bracket 12, the two are only connected by a flexible pipeline to realize the pipeline connection between the liquid cooling plate 13 and the liquid cooling plug fixed on the bracket 12, and there is no other rigid connection. In this way, when the bracket 12 moves, it cannot drive the liquid cooling plate 13 to move, so when the bracket 12 deviates, it cannot drive the liquid cooling plate 13 to deviate, and the liquid cooling plate 13 can flexibly match the height of the heating element to achieve floating relative to the bracket 12.

[0088] like Figure 2 As shown, the bracket 12 may have a water inlet channel 121 and a water outlet channel 122 inside, one end of the water inlet channel 121 is fixedly connected to the water inlet plug 14, and the other end is fixedly connected to the first end of the water supply hose 16, and the second end of the water supply hose 16 is fixedly connected to the water inlet interface 131 of the liquid cooling plate 13. One end of the water outlet channel 122 is fixedly connected to the water outlet plug 15, and the other end is fixedly connected to the first end of the water return hose 17, and the second end of the water return hose 17 is fixedly connected to the water outlet interface 132 of the liquid cooling plate 13.

[0089] Of course, in another possible implementation, the bracket 12 may not have the above-mentioned water inlet channel 121 and water outlet channel 122, and the bracket 12 may be just a frame structure, only fixing the water inlet plug 14 and the water outlet plug 15. In this case, one end of the water supply hose 16 is fixedly connected to the water inlet plug 14, and the other end is fixedly connected to the water inlet interface 131 of the liquid cooling plate 13. One end of the water return hose 17 is fixedly connected to the water outlet plug 15, and the other end is fixedly connected to the water outlet interface 132 of the liquid cooling plate 13.

[0090] It should be noted that in this case, it should be ensured that the force point is located on the bracket 12 rather than the water supply hose 16 and the water return hose 17 when the water inlet plug 14 and the water outlet plug 15 are plugged in and out, so as to avoid the water supply hose 16 and the water return hose 17 being disconnected from the water inlet plug 14 and the water outlet plug 15 during plugging and unplugging, causing cooling water leakage.

[0091] Since the liquid cooling plate 13 and the bracket 12 are only flexibly connected, in order to improve the stability of the liquid cooling plate 13 and avoid large shaking between the liquid cooling plate 13 and the bracket 12, Figure 3As shown, the side of the bracket 12 facing the liquid cooling plate 13 has a positioning pin 123. The liquid cooling plate 13 has a positioning hole 133 at the position corresponding to the positioning pin 123. At the same time, in order to ensure that the liquid cooling plate 13 can float relative to the bracket 12, the inner diameter of the positioning hole 133 needs to be larger than the outer diameter of the positioning pin 123, and the positioning pin 123 and the positioning hole 133 are in clearance fit. For example, Figure 3 As shown, there are two positioning pins 123 and two positioning holes 133 .

[0092] like Figure 4 , which is an exploded view of a PCB board assembly provided in an embodiment of the present application.

[0093] The PCB board assembly includes a PCB board 11 , a first sub-bracket 12 a and a second sub-bracket 12 b (the two constitute a bracket 12 ), a liquid cooling plate 13 , a water inlet plug 14 , a water outlet plug 15 , a water supply hose 16 and a water return hose 17 .

[0094] The PCB board 11 is fixedly connected to the first sub-bracket 12a, and the second sub-bracket 12b is fixedly connected to the first sub-bracket 12a, and the two can be connected by screws. The water inlet plug 14 and the water outlet plug 15 are fixed to the second sub-bracket 12b, and the positioning pin 123 is located on the first sub-bracket 12a.

[0095] It should be noted that the first sub-bracket 12a and the second sub-bracket 12b can be made into two separate structural components, or can be made into an integral structural component, which is not limited in the embodiment of the present application.

[0096] like Figure 5 , which is a schematic diagram of a bracket 12 (second sub-bracket 12b) provided in an embodiment of the present application.

[0097] The second sub-bracket 12b has two slide bars 124 on both sides, and the two slide bars 124 are adapted to the slideways in the corresponding slideway assembly, so as to facilitate the PCB board assembly to play a guiding role when plugging and unplugging the PCB board assembly. In addition, the second sub-bracket 12b also has a puller 125 on both sides, and the two pullers 125 correspond to the positions of the two slide bars 124 respectively. The function of the puller 125 is to help the PCB board assembly to be plugged into place when the PCB board assembly is inserted, and to lock the position of the PCB board assembly, and to provide a force part when the PCB board assembly is pulled out. The puller 125 can also be called an auxiliary puller, an auxiliary wrench, etc.

[0098] The second sub-bracket 12b may further include a plug fixing portion 120, and the plug fixing portion 120 has the above-mentioned water inlet channel 121 and water outlet channel 122. Figure 5As shown, the plug fixing portion 120 is located between the slide bars 124 on both sides. The first side of the plug fixing portion 120 is used to fix the water inlet plug 14 and the water outlet plug 15, and the second side is used to fix the water supply hose 16 and the water return hose 17, wherein the first side and the second side are perpendicular to each other, the second side faces the liquid cooling plate 13, and the first side can also be called the bottom side.

[0099] In order to make the PCB board assembly more accurately inserted into the liquid cooling socket during the insertion process, Figure 5 As shown, the PCB assembly further includes a guide pin 18. The guide pin 18 is fixed on the same side of the bracket 12 as the water inlet plug 14 and the water outlet plug 15, and the axial directions are parallel to each other. The guide pin 18 is configured to dock with the guide cylinder 26 of the water distributor. Figure 5 As shown, the guide pin 18 is fixed to a first side of the plug fixing portion 120 .

[0100] During the plug-in process of the PCB board assembly, the slide bars 124 on both sides of the bracket 12 first slide into the slide of the slide assembly. When it is about to be plugged into place, the guide pin 18 is inserted into the guide cylinder 26 on the water distributor 2, forming a more precise guide for the water inlet plug 14 and the water outlet plug 15, ensuring that the water inlet plug 14 and the water outlet plug 15 can be plugged into place smoothly.

[0101] To sum up, the embodiment of the present application provides a PCB board assembly, which can achieve quick plugging and unplugging. By adopting the water inlet plug 14 and the water outlet plug 15, the liquid cooling pipeline can be disconnected or connected while plugging and unplugging the PCB board 11, without unnecessary plugging and unplugging actions. At the same time, the PCB board assembly has no unnecessary pipelines, and water is uniformly taken through the water distributor.

[0102] Furthermore, the design that the liquid cooling plate 13 can float relative to the bracket 12 also ensures that during the plugging and unplugging process, the liquid cooling plate 13 always maintains stable contact with the heating element, thereby maintaining a high heat dissipation efficiency.

[0103] The present application also provides a water separator, such as Figure 6-10As shown, the water divider includes a water divider body 21, a water inlet connector 22, a water outlet connector 23, at least one water outlet socket 24 and at least one water inlet socket 25. The water divider body 21 has a water supply channel and a water return channel inside, the water supply channel includes a main water supply channel 211 and at least one branch water supply channel 212, and the water return channel includes a main return water channel 213 and at least one branch return water channel 214. One end of the main water supply channel 211 is fixedly connected to the water inlet connector 22, one end of the branch water supply channel 212 is communicated with the main water supply channel 211, and the other end is fixedly connected to the water outlet socket 24, and the water outlet socket 24 is configured to be plugged with the water inlet plug 14 of the PCB board assembly. One end of the main return water channel 213 is fixedly connected to the water outlet connector 23, one end of the branch return water channel 214 is communicated with the main return water channel 213, and the other end is fixedly connected to the water inlet socket 25, which is configured to be plugged into the water outlet plug 15 of the PCB board assembly.

[0104] The water distributor body 21 has a water supply channel and a water return channel inside, which plays a role in water distribution.

[0105] The water inlet connector 22 and the water outlet connector 23 are used to connect the main water distributor 4 . The water inlet connector 22 is used to introduce cooling water from the main water distributor 4 , and the water outlet connector 23 is used to output the cooling water in the water distributor 2 to the main water distributor 4 .

[0106] The water outlet socket 24 and the water inlet socket 25 are used to connect with the water inlet plug 14 and the water outlet plug 15 in the PCB board assembly. The water outlet socket 24 and the water inlet socket 25 can be collectively referred to as liquid cooling sockets, and the liquid cooling sockets can be automatically blocked when separated from the liquid cooling plug to prevent the cooling water in the pipeline from flowing out of the liquid cooling sockets. The specific implementation of the liquid cooling socket is not specifically limited in the embodiment of the present application. For example, the water outlet socket 24 and the water inlet socket 25 can adopt a blind plug connector (or a blind plug connector seat).

[0107] In addition, the water divider body 21 has a plug hole for the electrical connector of the PCB board 11 to pass through, so that the electrical connector of the PCB board 11 can be plugged into the PCB board slot through the plug hole.

[0108] The solution shown in the embodiment of the present application provides a water divider 2, which has a water supply channel and a return water channel. The water supply channel includes a main water supply channel 211 and at least one branch water supply channel 212, and the return water channel includes a main return water channel 213 and at least one branch return water channel 214.

[0109] In the water distribution process, the cooling water entering from the water inlet connector 22 first enters the main water supply channel 211, then flows into the branch water supply channel 212, and then flows into the liquid cooling plate through the water outlet socket 24. The cooling water flowing out of the liquid cooling plate first enters the branch return water channel 214 through the water inlet socket 25, then enters the main return water channel 213 through the branch return water channel 214, and then flows out through the water outlet connector 23.

[0110] like Figure 7 As shown, a schematic diagram of an upper cover plate hiding the water distributor body 21 is shown, exposing the main water supply channel 211 and the branch water supply channel 212. Figure 8 As shown, a cross-sectional view of a water distributor body 21 is shown, exposing the main water supply channel 211 and the branch water supply channel 212.

[0111] like Fig. 9 As shown, a schematic diagram of a lower cover plate hiding the water distributor body 21 is shown, exposing the main return water flow channel 213 and the branch return water flow channel 214. Fig.10 As shown, a cross-sectional view of a water distributor body 21 is shown, exposing the main water return channel 213 and the branch water return channel 214.

[0112] Exemplarily, there are multiple branch water supply channels 212 and multiple branch water return channels 214. Multiple branch water supply channels 212 are distributed in parallel, and multiple branch water return channels 214 are distributed in parallel.

[0113] Exemplarily, the main water supply channel 211 is perpendicular to the axial direction of the branch water supply channel 212 , and the main water return channel 213 is perpendicular to the axial direction of the branch water return channel 214 .

[0114] By arranging the water supply channel and the water return channel in the above manner, the water supply channel and the water return channel cover a smaller area, and the area of ​​the water divider body 21 is smaller, so that the water divider can be easily installed in the chassis of the electronic equipment.

[0115] In order to make the PCB board assembly more accurately inserted into the liquid cooling socket during the insertion process, Figure 6 As shown, the water distributor further includes a guide cylinder 26. The guide cylinder 26 is fixed on the same side of the water distributor body 21 as the water outlet socket 24 and the water inlet socket 25, and the axial directions are parallel to each other. The guide cylinder 26 is configured to dock with the guide pin 18 in the PCB board assembly.

[0116] During the plug-in process of the PCB board assembly, the slide bars 124 on both sides of the bracket 12 first slide into the slide of the slide assembly. When it is about to be plugged into place, the guide pin 18 is inserted into the guide cylinder 26 on the water divider 2, forming a more precise guide for the water inlet plug 14 and the water outlet plug 15, ensuring that the water inlet plug 14 and the water outlet plug 15 can be smoothly plugged into the water outlet socket 24 and the water inlet socket 25.

[0117] It should be noted that the water divider provided in the embodiment of the present application can also be considered to belong to a PCB board assembly, that is, the PCB board assembly also includes the water divider.

[0118] The present application also provides a liquid cooling module, such as Fig.11 As shown, the liquid cooling module includes a PCB board assembly 1, a water distributor 2 and a slide assembly 3. The slide assembly 3 includes a first slide member 31 and a second slide member 32, and the first slide member 31 and the second slide member 32 are located on both sides of the PCB board assembly 1 and the water distributor 2, and the first slide member 31 and the second slide member 32 each have at least one slide. Both sides of the bracket 12 of the PCB board assembly 1 are respectively located in two opposite slides. The water inlet plug 14 of the PCB board assembly 1 is plugged into the water outlet socket 24 of the water distributor 2, and the water outlet plug 15 of the PCB board assembly 1 is plugged into the water inlet socket 25 of the water distributor 2.

[0119] Among them, the slide assembly 3 includes a first slide member 31 and a second slide member 32. The first slide member 31 and the second slide member 32 have slides on opposite sides. The slide bars 124 on both sides of the bracket 12 of the PCB board assembly 1 can slide along the slide to form an upward plug-in and pull-out with a fixed sliding direction.

[0120] The cooling water circulation process of the liquid cooling module provided in the embodiment of the present application is as follows:

[0121] The cooling water of the main water distributor 4 flows into the interior of the water distributor 2 through the water inlet connector 22 of the water distributor 2. The cooling water entering the interior of the water distributor 2 enters the interior of the liquid cooling plate 13 through the water outlet socket 24 of the water distributor 2, the water inlet plug 14 of the PCB board assembly 1, the water supply hose 16 and the water inlet interface 131 of the liquid cooling plate 13.

[0122] The cooling water entering the liquid cooling plate 13 carries the heat of the heating element and flows out from the water outlet interface 132 of the liquid cooling plate 13 , and enters the interior of the water distributor 2 through the return hose 17 , the water outlet plug 15 and the water inlet socket 25 , and then enters the main water distributor 4 through the water outlet connector 23 of the water distributor 2 .

[0123] like Fig.12FIG. 1 is a schematic diagram of an assembly of a water divider 2 and a slide assembly 3 provided in an embodiment of the present application. In the schematic diagram, a first slide member 31 and a second slide member 32 of the slide assembly 3 are respectively fixed on both sides of the water divider 2, and for example, they can be fixed by screws. Fig.12 It can be seen from the figure that the water inlet connector 22 of the water divider 2 is located on the inner side of the second slide member 32 , and the water outlet connector 23 of the water divider 2 is located on the outer side of the second slide member 32 .

[0124] It should be noted that, in actual applications, the slideway assembly 3 may not be fixed together with the water distributor 2, but may be fixed separately on the main board. In this way, the tolerance configuration of the PCB board 1 assembly is better.

[0125] like Fig.13 As shown, it is a schematic diagram of a liquid cooling module provided in an embodiment of the present application and provided with a PCB board assembly 1 installed.

[0126] like Fig.14 As shown, it is a schematic diagram of a liquid cooling module in which all PCB board components 1 provided in an embodiment of the present application are installed in place.

[0127] Below, refer to Figure 15-17 , the process of inserting the PCB board assembly 1 provided in the embodiment of the present application into the water divider 2 and the slideway assembly 3 is described:

[0128] like Fig.15 As shown, the PCB board assembly 1 is placed above the slideway assembly 3 and slides downward along the slideway in the slideway assembly 3. During this process, the puller 125 maintains a vertical posture under the action of the rotation spring.

[0129] like Fig.16 As shown, the PCB board assembly 1 is plugged into place, and the puller 125 is pressed down. When the liquid cooling connector and the liquid cooling socket are in contact, the puller 125 just reaches the fulcrum, and then the puller 125 is rotated to apply a certain force on the PCB board assembly 1, so that the PCB board assembly 1 and the water distributor 2 are finally assembled in place, and the liquid cooling plug and the liquid cooling socket are completely connected.

[0130] like Fig.17 As shown, it is a schematic diagram of the PCB board assembly 1 being fully plugged into place.

[0131] Below, refer to Fig.18 , the principle of the extractor 125 is explained:

[0132] like Fig.18 As shown, the extractor 125 includes a main body 125a, a locking slider 125b, a compression spring 125c and a rotation spring 125d.

[0133] The main body 125a is rotatably connected to the main body of the bracket 12, and the puller 125 has a vertical upward movement tendency through the rotation spring 125d. Under normal conditions, the puller 125 always maintains a vertical state ( Fig.18 The state shown is a horizontal state). In the vertical state, the clamping end 125e of the main body 125a is retracted, and will not prevent the slide bar 124 from sliding into the slideway normally.

[0134] A portion of the locking slider 125b is located inside the main body 125a, and another portion is located outside the main body 125a. Under the action of the compression spring 125c, the locking end 125f of the locking slider 125b extends to the outside of the main body 125a.

[0135] Next, the use process of the extractor 125 is described:

[0136] During the insertion of PCB board component 1:

[0137] When the PCB assembly 1 is about to be inserted into place, the puller 125 is rotated, and the clamping end 125e of the puller 125 gradually extends out and contacts the top of the slideway slot 30 of the slideway (such as Fig.18 As shown in FIG. 1 ). The puller 125 is continuously rotated, and the puller 125 uses the top of the slot as a fulcrum to pry the entire PCB board assembly 1 and continue to move downward until it is plugged into place.

[0138] During the rotation process, the locking end 125f of the locking slider 125b contacts the outer wall of the bracket slot 126 on the bracket 2, and retracts under the push of the outer wall until it enters the inside of the bracket slot 126. Then, under the action of the compression spring 125c, the locking end 125f extends into the bracket slot 126 and is locked in the bracket slot 126.

[0139] Since both ends of the puller 125 are respectively held in the slideway slot 30 and the bracket slot 126 , the position of the PCB assembly 1 is locked.

[0140] During the process of pulling out the PCB assembly 1:

[0141] First, the locking slider 125b is slid to retract the locking end 125f from the bracket slot 126. Under the action of the rotation spring 125d, the puller 125 rotates toward the vertical state, and the locking end 125e gradually retracts from the slide slot 30. The locking state of the PCB assembly 1 is released, and the PCB assembly 1 can be pulled out smoothly.

[0142] The present application also provides a liquid cooling system. Fig.19As shown, the liquid cooling system includes a main water distributor 4 and the above-mentioned liquid cooling module 5. The main water distributor 4 has a main water inlet joint 41, a main water outlet joint 42, a first branch water outlet joint 43 and a first branch water inlet joint 44. The main water inlet joint 41 and the main water outlet joint 42 are configured to be connected to the water tank. The first branch water outlet joint 43 is connected to the water inlet connector 22 of the water distributor of the liquid cooling module 5 through a liquid supply line, and the first branch water inlet joint 44 is connected to the water outlet connector 23 of the water distributor 5 through a liquid return line.

[0143] The water inlet joint or the water outlet joint of the main water distributor 4 is divided according to whether the water enters the interior of the main water distributor 4 or flows out of the main water distributor 4 .

[0144] When the liquid cooling system is working, the cooling water in the water tank enters the main water distributor 4 through the main water inlet joint 41, and then flows into the water distributor 2 through the first branch water outlet joint 43, the liquid supply pipeline, and the water inlet connector 22 of the water distributor 2. The cooling water entering the water distributor 2 enters the interior of the liquid cooling plate 13 through the water outlet socket 24 of the water distributor 2, the water inlet plug 14 of the PCB board assembly 1, the water supply hose 16, and the water inlet interface 131 of the liquid cooling plate 13.

[0145] The cooling water entering the liquid cooling plate 13 carries the heat of the heating element and flows out from the water outlet interface 132 of the liquid cooling plate 13, and enters the interior of the water distributor 2 through the water return hose 17, the water outlet plug 15 and the water inlet socket 25. The cooling water entering the water distributor 2 enters the interior of the main water distributor 4 through the water outlet connector 23, the return liquid pipeline and the first branch water inlet connector 44, and flows back into the water tank through the main water outlet connector 42.

[0146] By repeating the above cycle continuously, the heat emitted by the heating element is continuously taken out.

[0151] The cooling water entering the liquid cooling plate of the CPU liquid cooling module 6 carries the heat of the heating element and flows out from the water outlet joint of the liquid cooling plate, and enters the interior of the main water distributor 4 through the return liquid pipeline and the second branch water inlet joint 46, and flows back into the water tank through the main water outlet joint 42.
