Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling plates, and in particular to a flow channel separation type liquid cooling plate. Background Art

[0002] Liquid cooling plates are usually made of high thermal conductivity materials, such as aluminum alloy, copper alloy, etc. The interior is precision-processed to form a closed coolant flow channel, and the exterior is in close contact with the heat-generating components through the cold plate. Based on the principle of heat conduction, heat is transferred from the heat source to the coolant, and then the circulating coolant takes the heat away. It is mainly used in electronic equipment, such as battery packs, to efficiently transfer and dissipate heat.

[0003] In the prior art, some flow channels of liquid cooling plates are designed as one channel, which is evenly laid on the cold plate by bending. The advantage is that the flow rate of the coolant in the channel is the same, but once the channel fails, the entire liquid cooling plate will fail. Some liquid cooling plates are designed with multiple flow channels, but each flow channel has a different length and the same inlet and outlet positions, so the flow of the coolant in different flow channels may be uneven, resulting in thermal uniformity problems, thereby affecting the overall thermal management effect.

[0004] In addition, most of the current liquid cooling plates are of integrated design. When a single flow channel has a fault such as coolant leakage, it is usually necessary to stop working as a whole for repair or replace it with a new one, which makes other intact flow channels unable to work normally, thereby reducing the stability and reliability of the system. At the same time, replacing the entire liquid cooling plate also increases the cost of heat dissipation of electronic equipment.

[0005] In view of this, the present invention proposes a flow channel separation type liquid cooling plate to make up for and improve the deficiencies of the prior art. Summary of the invention

[0008] The uniform heat dissipation mechanism is used to make the coolant flow path uniform and to dismantle part of the pipeline and replace it with a new one after a device failure occurs;

[0009] The separate isolation mechanism is used to close the pipeline separately when leakage occurs on the liquid cooling plate.

[0010] Preferably, the uniform heat dissipation mechanism includes a flow channel body snap-connected to the top of the cold plate body, and the flow channel bodies are provided in plurality, both ends of the plurality of flow channel bodies are fixedly connected with a diversion chamber, the top of the diversion chamber on one side is fixedly connected with a liquid inlet pipe, and the top of the diversion chamber on the other side is fixedly connected with a liquid outlet pipe, the total length of the plurality of flow channel bodies is set to be the same, the S-shaped bending degree of the flow channel body is set to increase one by one from the direction away from the liquid inlet pipe to the direction close to the liquid inlet pipe, and the top of the cold plate body is provided with a plurality of grooves whose sizes are matched with the sizes of the flow channel bodies.

[0011] Preferably, the uniform heat dissipation mechanism also includes a pair of connecting rings threadedly connected to both sides of the flow channel body, and multiple pairs of the connecting rings are movably connected to the top of the cold plate body. Multiple pairs of sliding grooves compatible with the connecting rings are provided on the top of the cold plate body, and the outer wall of the flow channel body is provided with threaded grooves compatible with the connecting rings. The lengths of multiple threaded grooves are greater than the width of the connecting rings. A pair of leak-proof rings are fixedly connected to the inner wall of one side of the flow channel body, and the outer walls of multiple pairs of leak-proof rings are slidably clamped to the inner wall of the other side of the flow channel body.

[0012] Preferably, the separate isolation mechanism includes a support plate fixedly connected to the outer wall of the liquid inlet pipe, a plurality of limit plates are fixedly connected to the edge of the support plate, the inner walls of the plurality of limit plates are rotatably connected to threaded columns, the sides of the plurality of threaded columns away from the limit plates are rotatably connected to the inner wall of the liquid inlet pipe, the side of the threaded column close to the limit plate is fixedly connected to a knob, the middle part of the threaded column is threadedly connected to a sliding block, the bottoms of the plurality of sliding blocks are slidably connected to the top of the support plate, the side of the sliding block away from the threaded column is fixedly connected to a pull rope, and the end of the pull rope away from the sliding block slides through the inner wall of the liquid inlet pipe.

[0013] Preferably, the separate isolation mechanism also includes a spherical plug fixedly connected to the bottom of the pull rope, and multiple spherical plugs are movably connected to the inner wall of the diversion chamber, and the side of the spherical plug away from the diversion chamber is fixedly connected to a return spring, and the ends of the return springs away from the spherical plug are fixedly connected to a mounting ring block, and the outer walls of the multiple mounting ring blocks are fixedly connected to the inner wall of the flow channel body.

[0014] Preferably, a plurality of circular holes are opened in the middle of the diversion chamber, and the diameters of the plurality of circular holes are all smaller than the diameter of the spherical plug.

[0015] Preferably, each pair of connecting rings is located on the outer wall of the flow channel body near the bend.

[0016] Preferably, the outer wall of the flow channel body is movably sleeved with multiple fixing parts, the bottoms of the multiple fixing parts are fixedly connected to the top of the cold plate body, the fixing parts are arc-shaped and the number of raised arcs matches the number of bends of the flow channel body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the setting of uniform heat dissipation mechanism, the flow path of the coolant in the cold plate body is designed as multiple independent flow channel bodies. These flow channel bodies are curved and laid horizontally on the cold plate body to prevent the mixing of coolants in multiple flow channels from causing the flow rate to decrease, or the leakage of coolant causing electronic equipment failure. At the same time, the multi-flow channel design can increase the contact area between the coolant and the heat source, and each flow channel works independently, which helps the heat distribution on the heating element to be absorbed and dissipated more evenly, which can improve the heat dissipation efficiency. In addition, the S-shaped bending degree of the flow channel body is set to increase one by one from the direction away from the liquid inlet pipe to the direction close to the liquid inlet pipe, that is, the gradual bending treatment, so that the total path of each flow channel is changed, so that the flow speed of the coolant in different flow channels is the same, the heat exchange effect is improved, and the problem of uneven coolant flow and thermal uniformity is solved, thereby improving the overall thermal management effect of the liquid cold plate;

[0019] 2. Through the arrangement of the thread groove and the connecting ring, since the length of the thread groove is greater than the width of the connecting ring, the staff can rotate the connecting ring to the outer wall of the flow channel body on one side, separate the flow channel body, and take out the bending part of the flow channel body with a higher damage rate for inspection and replacement, so as to increase the service life of the liquid cooling plate, reduce the frequency of replacing the liquid cooling plate, and thus save the heat dissipation cost;

[0020] 3. The fixing piece is in an arc wave shape, and the number of raised arcs is matched with the number of bends of the flow channel body, so that the fixing piece and the flow channel body can be more closely fitted, which increases the stability of the flow channel body installed on the cold plate body. At the same time, the close fit between the fixing piece and the flow channel body also helps to improve the heat dissipation effect;

[0021] 4. Through the setting of a separate isolation mechanism, an independent closing system is set at the liquid inlet pipe, and a ball plug is used in conjunction with a pull rope. When a certain flow channel fails and the liquid cannot continue to flow in, the staff can pull the pull rope to fit the ball plug to the diversion chamber to plug the round hole. In this way, when a single flow channel has a coolant leak or other faults, this flow channel can be closed directly from the source to avoid continuous leakage. Even if a single flow channel fails, it will not affect the normal operation of other flow channels, thereby improving the stability and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiments of the present invention

[0036] Please refer to Figures 1 to 8As shown, a flow channel separation type liquid cold plate includes a cold plate body 1, and also includes: a uniform heat dissipation mechanism 3 and a separate isolation mechanism 4, the uniform heat dissipation mechanism 3 is located at the top of the cold plate body 1, and the separate isolation mechanism 4 is located at the corner of the cold plate body 1;

[0037] The uniform heat dissipation mechanism 3 is used to make the coolant flow path the same and to dismantle part of the pipeline and replace it with a new one after a device failure occurs;

[0038] The separate isolation mechanism 4 is used to close the pipeline of the liquid cooling plate separately when leakage occurs;

[0039] The uniform heat dissipation mechanism 3 includes a flow channel body 31 that is clamped on the top of the cold plate body 1. The flow channel body 31 is provided with a plurality of flow channel bodies 31. Both ends of the plurality of flow channel bodies 31 are fixedly connected with a diversion chamber 33. The top of the diversion chamber 33 on one side is fixedly connected with a liquid inlet pipe 34. The top of the diversion chamber 33 on the other side is fixedly connected with a liquid outlet pipe 32. The total length of the plurality of flow channel bodies 31 is set to be the same. The S-shaped bending degree of the flow channel body 31 is set to increase one by one from the direction away from the liquid inlet pipe 34 to the direction close to the liquid inlet pipe 34. The top of the cold plate body 1 is provided with a plurality of grooves 36 with sizes that match the sizes of the flow channel body 31.

[0040] The uniform heat dissipation mechanism 3 also includes a pair of connecting rings 35 threadedly connected to both sides of the flow channel body 31, and multiple pairs of connecting rings 35 are movably connected to the top of the cold plate body 1. Multiple pairs of sliding grooves 38 adapted to the connecting rings 35 are provided on the top of the cold plate body 1. The outer wall of the flow channel body 31 is provided with thread grooves 37 adapted to the connecting rings 35. The lengths of the multiple thread grooves 37 are greater than the width of the connecting rings 35. A pair of anti-leakage rings 39 are fixedly connected to the inner wall of one side of the flow channel body 31, and the outer walls of the multiple pairs of anti-leakage rings 39 are slidably clamped to the inner wall of the other side of the flow channel body 31.

[0041] Each pair of connecting rings 35 is located on the outer wall of the flow channel body 31 near the bend;

[0042] The outer wall of the flow channel body 31 is movably sleeved with a plurality of fixing members 2, the bottoms of the plurality of fixing members 2 are fixedly connected to the top of the cold plate body 1, the fixing members 2 are in an arc wave shape, and the number of raised arcs matches the number of bends of the flow channel body 31;

[0043] Among them: the diversion chamber 33 is used to increase the width and effectively connect with the flow channel body 31, the slide groove 38 facilitates the thread groove 37 to move and disassemble the flow channel body 31, and the leak-proof ring 39 is used to stabilize the connection when the flow channel body 31 is docked and increase the sealing.

[0044] The effects achieved by this embodiment are as follows: in the prior art, each flow channel has a different length but the same inlet and outlet positions, so the flow of the coolant in different flow channels may be uneven, resulting in thermal uniformity problems, which in turn affects the overall thermal management effect. Compared with the prior art, through the implementation of this embodiment, the uniform heat dissipation mechanism 3 is set up to design the flow path of the coolant in the cold plate body 1 into multiple independent flow channel bodies 31 to prevent the mixing or leakage of the coolant, and through the gradual bending treatment of the flow channel body 31, it is ensured that the total path of each flow channel is the same, so that the flow speed of the coolant in different flow channels is the same, thereby improving the heat exchange effect.

[0045] Further examples:

[0046] Please refer to Figure 1 , Figures 4 to 6 As shown, the separate isolation mechanism 4 includes a support plate 41 fixedly connected to the outer wall of the liquid inlet pipe 34, a plurality of limit plates 44 are fixedly connected to the edge of the support plate 41, the inner walls of the plurality of limit plates 44 are rotatably connected to threaded columns 42, the sides of the plurality of threaded columns 42 away from the limit plates 44 are rotatably connected to the inner wall of the liquid inlet pipe 34, the side of the threaded columns 42 close to the limit plates 44 is fixedly connected to a knob 43, the middle part of the threaded column 42 is threadedly connected to a sliding block 45, the bottoms of the plurality of sliding blocks 45 are slidably connected to the top of the support plate 41, the sides of the sliding blocks 45 away from the threaded columns 42 are fixedly connected to a draw rope 46, and the ends of the draw ropes 46 away from the sliding blocks 45 slide through the inner wall of the liquid inlet pipe 34;

[0047] The separate isolation mechanism 4 further includes a spherical plug 47 fixedly connected to the bottom of the pull rope 46, and the plurality of spherical plugs 47 are movably connected to the inner wall of the diversion chamber 33, and the side of the spherical plug 47 away from the diversion chamber 33 is fixedly connected to a return spring 48, and the ends of the plurality of return springs 48 away from the spherical plug 47 are fixedly connected to a mounting ring block 49, and the outer walls of the plurality of mounting ring blocks 49 are fixedly connected to the inner wall of the flow channel body 31;

[0048] A plurality of circular holes 410 are provided in the middle of the flow dividing chamber 33, and the diameters of the plurality of circular holes 410 are all smaller than the diameter of the spherical plug 47;

[0049] The number of the limiting plates 44 is consistent with that of the flow channel body 31 , the pull rope 46 is set to be inelastic, and the diameter of the ball plug 47 is smaller than the inner diameter of the flow channel body 31 .

[0050] The effects achieved by this embodiment are as follows: In the prior art, when a single flow channel has a fault such as coolant leakage, it is usually necessary to stop the entire liquid cooling plate from working, repair it or replace it with a new liquid cooling plate, so that other intact flow channels cannot work normally, thereby reducing the stability and reliability of the system. At the same time, replacing the entire liquid cooling plate also increases the cost of heat dissipation of electronic equipment. Compared with the prior art, through the implementation of this embodiment, a separate isolation mechanism 4 is set up to be able to use a ball plug 47 in conjunction with a pull rope 46. When a certain flow channel body 31 fails and liquid cannot continue to flow into it, the staff can pull the pull rope 46 to fit the ball plug 47 with the diversion chamber 33 to plug the round hole 410. When a single flow channel has a fault such as coolant leakage, this flow channel can be directly closed from the source to avoid continuous leakage.

[0051] The complete usage steps and working principle of the above embodiment are as follows:

[0052] In the initial state: the connecting ring 35 connects the flow channel body 31 to a sealed state, the fixing member 2 fixes the flow channel body 31 and the cold plate body 1, the sliding block 45 is located on the side close to the liquid inlet pipe 34, and the return spring 48 is in a naturally relaxed state.

[0053] When in use, the cold plate body 1 is installed close to the electronic equipment, and then the cooling liquid is introduced from the liquid inlet pipe 34 through the external water pump, and the cooling liquid is diverted to the multiple flow channel bodies 31 through the diversion chamber 33, and finally merged into the diversion chamber 33 on the other side, and then flows out from the liquid outlet pipe 32. In this way, the cooling liquid continues to flow in the flow channel body 31 laid on the plane, and the heat of the electronic equipment can be taken away. Since the total length of the multiple flow channel bodies 31 is set to be the same, and the S-shaped bending degree of the flow channel body 31 is set from the direction away from the liquid inlet pipe 34 to the direction close to the liquid inlet pipe 34 The distance between the liquid inlet pipe 34 and the liquid outlet pipe 32 is short in straight line and the flow rate of the coolant is fast, but the length and liquid flow resistance are increased by the S-shaped bend. Through the coordinated design of the two, the distance between different flow channel bodies 31 can be different according to the number of S-shaped bends and the resistance of liquid flow, but ultimately the flow rate of the coolant in each flow channel body 31 is the same, thereby ensuring the uniformity of the heat dissipation of the coolant, and preventing the problem that different flow channel bodies 31 arrive at the liquid outlet pipe 32 one after another, causing uneven heat dissipation of the electronic equipment;

[0054] Furthermore, when the liquid cooling plate has a fault such as leakage, the flow channel body 31 can be inspected and repaired by disassembling the flow channel body 31. Since the length of the threaded groove 37 is greater than the width of the connecting ring 35, the staff can rotate the connecting ring 35 to slide from one side of the slide groove 38 to the other side, release the limit of the middle part of the flow channel body 31, so that the flow channel body 31 can be separated near the bending part, and the anti-leakage ring 39 can be slid out from the inner wall of the flow channel body 31. In this way, the limit of a pair of connecting rings 35 is released, and then the fixing member 2 is removed, and the bending part of the flow channel body 31 with a high damage rate can be taken out for inspection and replacement, so as to increase the service life of the liquid cooling plate. The fixing member 2 is in the shape of an arc wave and the number of raised arcs is matched with the number of bends of the flow channel body 31, so that the fixing member 2 can fit the flow channel body 31 more closely, and the stability of the flow channel body 31 installed on the cold plate body 1 is increased;

[0055] Please refer to the above working process Figures 1 to 3 , Figures 7 and 8 .

[0056] Furthermore, when the coolant normally flows into the flow channel body 31, since the sliding block 45 is located at the initial position close to the liquid inlet pipe 34, the pull rope 46 is in a relaxed and extended state, and the pull rope 46 has no pulling force on the ball plug 47. The external liquid pump will pump the coolant into the liquid inlet pipe 34. When the coolant reaches the ball plug 47, the squeezing force of the liquid can push the ball plug 47 into the flow channel body 31, so that the ball plug 47 compresses the reset spring 48, and then the liquid flows into the flow channel body 31 from the round hole 410, and passes through the gap between the ball plug 47 and the flow channel body 31, and continues to flow in. When a failure occurs in a certain flow channel body 31, such as leakage, in order to ensure the normal operation of the electronic equipment, the liquid cannot continue to be passed in to avoid the liquid entering the electronic equipment and causing damage to the electronic equipment. The staff can rotate the knob 43 to drive the threaded column 42 to rotate, so that the sliding block 45 moves from the initial state toward the direction of the knob 43, and pulls the pull rope 46 toward the outside of the liquid inlet pipe 34 through the sliding block 45 until the ball plug 47 fits with the diversion chamber 33 and the round hole 410 is blocked. At this time, the return spring 48 returns to the initial state, achieving the effect of closing the single flow channel body 31 from the source to avoid continuous leakage. Even if a single flow channel fails, it will not affect the normal operation of other flow channels.

[0057] Please refer to the above working process Figure 1 , Figures 4 to 6 .
