Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation of optical modules, and in particular to an elastic liquid cooling device for pluggable optical modules. Background Art

[0002] An optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals. After transmitting through optical fibers, the receiving end converts the optical signals into electrical signals to achieve information transmission.

[0003] At present, as the integration level of optical modules becomes higher and higher, the heat density of the chips in the optical modules is also increasing. When the heat density of the chips is too high, the heat will be concentrated in the chips and difficult to dissipate, which will easily form local high-temperature areas in the optical modules, seriously affecting the optoelectronic performance of the optical modules. Therefore, the heat dissipation problem becomes particularly important.

[0004] Chinese patent publication number CN219610420U discloses a cold plate comprising a plate body and a floating pressure regulating cavity. A cold plate flow channel is provided in the plate body for communicating with an external circulating cooling device, and the floating pressure regulating cavity is disposed inside the plate body.

[0005] During the use of the above technology, the cold plate is usually installed in a fixed manner, and the cooling of the optical module is achieved through heat transfer after contact with the cold plate. However, since the optical module needs to be pluggable, after a long period of use, the contact surface of the optical module and the cold plate will gradually produce a gap due to friction. This will cause the heat transfer effect between the optical module and the cold plate to deteriorate, which will greatly affect the heat dissipation effect of the optical module, thus having some shortcomings. Summary of the Invention

[0006] In order to improve the problem that a gap is formed between the optical module and the cold plate during long-term plug-in and plug-out use, thereby affecting the cooling effect of the optical module, the present application provides an elastic liquid cooling device for a plug-in optical module.

[0007] The present application provides an elastic liquid cooling device for a pluggable optical module using the following technical solution: A flexible liquid cooling device for a pluggable optical module includes a fiber optic cage, on which a plurality of optical modules are pluggably mounted, the plurality of optical modules being arranged along the width of the fiber optic cage; the fiber optic cage being provided with a plurality of contact ports, at which a plurality of internally hollow liquid cooling plates are slidably mounted, the liquid cooling plates corresponding one-to-one to the contact ports; the fiber optic cage being detachably provided with a liquid inlet pipe and a liquid outlet pipe; and a connecting pressure assembly being provided on the fiber optic cage, the connecting pressure assembly being used to connect the two ends of the liquid cooling plate to the liquid inlet pipe and the liquid outlet pipe, respectively, and to press the liquid cooling plate against the optical module.

[0008] By adopting the above technical solution, when the optical module is inserted into the optical fiber cage, the pressure-applying assembly is connected to press the liquid cooling plate against the optical module. At the same time, the liquid inlet and outlet pipes are connected to the pressure-applying assembly to allow the coolant to continuously flow through the liquid cooling plate. The liquid cooling plate removes the heat generated by the optical module through heat transfer, thereby reducing the temperature of the optical module. Since the position of the liquid cooling plate can be changed and can always be in close contact with the optical module, the problem of a gap between the optical module and the liquid cooling plate caused by friction during insertion and removal is solved, thereby allowing the optical module to always maintain a good cooling effect.

[0009] Optionally, a guiding slope is provided on one end of the liquid cooling plate toward the insertion end of the optical module, and the guiding slope is inclined along a direction from the liquid cooling plate to the optical module toward the insertion end of the optical module.

[0010] By adopting the above technical solution, during the insertion process of the optical module, the insertion end of the optical module will abut the guiding slope on the liquid cooling plate. As the optical module is continuously inserted, the liquid cooling plate will continue to rise, so that the optical module can be smoothly inserted into the optical fiber cage.

[0011] Optionally, a plurality of diverter strips are provided inside the liquid cooling plate, and the plurality of diverter strips are evenly arranged along the length direction of the liquid inlet pipe.

[0012] By adopting the above technical solution, the diverter strips evenly disperse the coolant in the liquid cooling plate during the process of the coolant flowing into and out of the liquid cooling plate, thereby making the temperature of the contact surface between the liquid cooling plate and the optical module tend to be consistent. At the same time, the diverter strips increase the contact area between the coolant and the liquid cooling plate, thereby improving the heat exchange efficiency between the liquid cooling plate and the optical module.

[0013] Optionally, the connecting pressure assembly includes a first elastic connecting tube and a second elastic connecting tube with the same structure, the first elastic connecting tube and the second elastic connecting tube are both made of elastic material, one end of the first elastic connecting tube is connected to the liquid inlet pipe, and the other end is connected to an end of the liquid cooling plate close to the liquid outlet pipe, one end of the second elastic connecting tube is connected to the liquid outlet pipe, and the other end is connected to an end of the liquid cooling plate close to the liquid inlet pipe.

[0014] By adopting the above technical solution, during the process of inserting the optical module into the optical fiber cage, as the insertion end of the optical module abuts the guiding inclined surface, the liquid cooling plate slides upward, and at the same time, the first elastic connecting tube and the second elastic connecting tube deform simultaneously until the optical module is fully inserted into the optical fiber cage. At this time, the restoring deformation force of the first elastic connecting tube and the second elastic connecting tube presses the liquid cooling plate tightly against the optical module, and the coolant can flow into and out of the liquid cooling plate through the first elastic connecting tube and the second elastic connecting tube, thereby continuously cooling the optical module.

[0015] Optionally, cross sections of the first elastic connecting tube and the second elastic connecting tube are both wavy.

[0016] By adopting the above technical solution, the restoring deformation force of the first elastic connecting tube and the second elastic connecting tube is enhanced, which is conducive to improving the pressing effect of the liquid cooling plate on the optical module and reducing the possibility of a gap between the liquid cooling plate and the optical module.

[0017] Optionally, the connecting pressure component includes a liquid hose for connecting the liquid cooling plate and the liquid inlet pipe, and the liquid cooling plate and the liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are both provided with square cross tubes, and the square cross tubes are sleeved on the liquid hoses. A limiting frame is provided on the liquid cooling plate, and the limiting frame is sleeved on the square cross tube. There is a distance between the two sides of the square cross tube in the vertical direction and the inner side wall of the limiting frame. A top plate is provided on the liquid inlet pipe and the liquid outlet pipe and is located above the limiting frame. A compression spring is supported between the top plate and the limiting frame.

[0018] By adopting the above technical solution, during the process of inserting the optical module into the optical fiber cage, as the insertion end of the optical module abuts the guiding inclined surface, the liquid cooling plate drives the limit frame to slide upward synchronously, and the compression spring is compressed until the optical module is fully inserted into the optical fiber cage. At this time, the restoring deformation force of the compression spring causes the liquid cooling plate to press tightly against the optical module. In the process of the coolant flowing into and out of the liquid cooling plate through the liquid hose, the liquid cooling plate removes the heat from the optical module by heat transfer, thereby continuously reducing the temperature of the optical module.

[0019] Optionally, a guide rod is vertically slidably provided on the top plate, and the compression spring is sleeved on the guide rod.

[0020] By adopting the above technical solution, the possibility of the compression spring accidentally escaping from between the top plate and the limiting frame is reduced.

[0021] Optionally, a tube bevel is provided on the square cross tube, and the tube bevel on the square cross tube on the liquid inlet pipe is inclined along the direction from the square cross tube to the liquid cooling plate toward the liquid outlet pipe, and a locking shaft is slidably provided on the tube bevel of the square cross tube, and a pressure wheel is coaxially sleeved on the locking shaft, and the pressure wheel is used to press the liquid hose against the inner wall of the square cross tube, and a frame bevel is provided on the limit frame on the square cross tube which is sleeved on the liquid inlet pipe, and the frame bevel is inclined along the direction from the square cross tube to the liquid cooling plate and back to the liquid outlet pipe, and the locking shaft slides in conjunction with the frame bevel on the limit frame.

[0022] By adopting the above technical solution, under the elastic force of the compression spring, the limit frame drives the liquid cooling plate to descend. During this process, the side walls of the frame inclined groove on the limit frame will squeeze the locking shaft. Since the limit frame can only slide vertically under the restriction of the guide rod, the locking shaft will slide downward along the inclined direction of the tube inclined groove, and the locking shaft will drive the pinch wheel to slide synchronously, and the pinch wheel will squeeze the liquid hose until the locking shaft moves to the lowest end of the inclined tube inclined groove. At this time, the liquid hose is completely compressed and closed by the pinch wheel, and the coolant cannot flow through the liquid hose, thereby achieving the effect of preventing the coolant from flowing through the liquid cooling plate without the optical module installed. For the liquid cooling plate with the optical module installed, the locking shaft will drive the pinch wheel to move to the highest end of the inclined tube inclined groove. At this time, the liquid hose is not squeezed and deformed by the pinch wheel, and the coolant can flow into and out of the liquid cooling plate through the liquid hose, thereby achieving the cooling effect on the optical module, which is beneficial to improving the utilization rate of the heat transfer of the coolant and reducing the energy consumption.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When the optical module is inserted into the fiber cage, the pressure component is connected to the liquid cooling plate to press it tightly against the optical module. At the same time, the liquid inlet and outlet pipes are connected to the pressure component to allow coolant to continuously flow through the liquid cooling plate. The liquid cooling plate removes the heat generated by the optical module through heat transfer, thereby reducing the temperature of the optical module. Because the position of the liquid cooling plate can be changed and it can always be in close contact with the optical module, it solves the problem of gaps between the optical module and the liquid cooling plate during the insertion and removal process, thereby ensuring that the optical module can always maintain a good cooling effect. 2. During the insertion of the optical module into the fiber cage, as the insertion end of the optical module abuts the guiding slope, the liquid cooling plate slides upward, and the first and second elastic connecting tubes simultaneously deform until the optical module is fully inserted into the fiber cage. At this time, the restoring deformation force of the first and second elastic connecting tubes presses the liquid cooling plate tightly against the optical module, allowing coolant to flow in and out of the liquid cooling plate through the first and second elastic connecting tubes, thereby continuously cooling the optical module. 3. Under the elastic force of the compression spring, the limit frame drives the liquid cooling plate to descend. During this process, the side wall of the frame inclined groove on the limit frame will squeeze the locking shaft. Since the limit frame can only slide vertically under the restriction of the guide rod, the locking shaft will slide downward along the inclined direction of the tube inclined groove, and the locking shaft will drive the pinch wheel to slide synchronously, and the pinch wheel will squeeze the liquid hose until the locking shaft moves to the lowest end of the inclined tube inclined groove. At this time, the liquid hose is completely compressed and closed by the pinch wheel, and the coolant cannot flow through the liquid hose, thereby achieving the effect of preventing the coolant from flowing through the liquid cooling plate without the optical module installed. For the liquid cooling plate with the optical module installed, the locking shaft will drive the pinch wheel to move to the highest end of the inclined tube inclined groove. At this time, the liquid hose is not squeezed and deformed by the pinch wheel, and the coolant can flow into and out of the liquid cooling plate through the liquid hose, thereby achieving the cooling effect on the optical module, which is beneficial to improving the utilization rate of the heat transfer of the coolant and reducing the energy consumption.

[0031] The following is combined with Figures 1-6 This application is described in further detail.

[0032] Example 1

[0033] An embodiment of the present application discloses an elastic liquid cooling device for a pluggable optical module.

[0034] Reference Figure 1 A flexible liquid cooling device for a pluggable optical module includes a fiber cage 1, on which a plurality of optical modules 2 are pluggably arranged, and the plurality of optical modules 2 are arranged along the width direction of the fiber cage 1.

[0035] Reference Figure 2 The optical fiber cage 1 is provided with a plurality of contact ports 3, and a plurality of internal hollow liquid cooling plates 4 are vertically slidably arranged at the contact ports 3 of the optical fiber cage 1. The cooling liquid flowing in the liquid cooling plates 4 can be ethylene glycol or water.

[0036] Reference Figure 2 The liquid cooling plate 4 corresponds to the contact port 3 one by one. The optical fiber cage 1 is bolted with a liquid inlet pipe 5 and a liquid outlet pipe 6. The optical fiber cage 1 is provided with a connecting pressure component 7. The connecting pressure component 7 is used to connect the two ends of the liquid cooling plate 4 with the liquid inlet pipe 5 and the liquid outlet pipe 6 respectively and to press the liquid cooling plate 4 against the optical module 2.

[0037] Reference Figure 3 The liquid cooling plate 4 is welded by multiple metal plates. Several diverter strips 9 are welded inside the liquid cooling plate 4. Both ends of the diverter strips 9 are evenly contacted with the inner wall of the liquid cooling plate 4. Several diverter strips 9 are evenly arranged along the length direction of the liquid inlet pipe 5. A guiding slope 8 is provided at the end of the liquid cooling plate 4 toward which the optical module 2 is inserted. The guiding slope 8 is inclined along the direction from the liquid cooling plate 4 to the optical module 2 toward the insertion end of the optical module 2.

[0038] When the coolant flows through the liquid cooling plate 4, the diverter strips 9 in the liquid cooling plate 4 evenly disperse the coolant in the liquid cooling plate 4, so that the temperature of the contact surface between the liquid cooling plate 4 and the optical module 2 tends to be consistent. At the same time, the diverter strips 9 increase the contact area between the coolant and the liquid cooling plate 4, thereby improving the heat exchange efficiency between the coolant and the liquid cooling plate 4, thereby improving the heat exchange efficiency between the liquid cooling plate 4 and the optical module 2.

[0039] Reference Figure 2 and Figure 3 The connecting pressure component 7 includes a first elastic connecting tube 71 and a second elastic connecting tube 72 with the same structure. The cross-sections of the first elastic connecting tube 71 and the second elastic connecting tube 72 are both wavy, and the first elastic connecting tube 71 and the second elastic connecting tube 72 are both made of elastic material.

[0040] Reference Figure 2 One end of the first elastic connecting tube 71 is connected to the liquid inlet pipe 5, and the other end is connected to the end of the liquid cooling plate 4 close to the liquid outlet pipe 6. One end of the second elastic connecting tube 72 is connected to the liquid outlet pipe 6, and the other end is connected to the end of the liquid cooling plate 4 close to the liquid inlet pipe 5.

[0041] During the process of inserting the optical module 2 into the fiber cage 1, the insertion end of the optical module 2 first abuts against the guiding slope 8 of the liquid cooling plate 4. At this time, the liquid cooling plate 4 slides upward under the action of the reaction force pushed by the optical module 2 until the optical module 2 is completely inserted into the fiber cage 1.

[0042] During this process, the first elastic connecting tube 71 and the second elastic connecting tube 72 are deformed at the same time, and at this time, the restoring deformation force of the first elastic connecting tube 71 and the second elastic connecting tube 72 will press the liquid cooling plate 4 tightly against the optical module 2. The heat generated by the optical module 2 during operation is transferred to the liquid cooling plate 4 through heat transfer, and the heat on the liquid cooling plate 4 is also transferred to the coolant in the liquid cooling plate 4 through heat transfer.

[0043] The cooling liquid from the liquid inlet pipe 5 flows into the liquid outlet pipe 6 along the order of passing through the first elastic connecting pipe 71, the liquid cooling plate 4 and the second elastic connecting pipe 72, so that the low-temperature cooling liquid continuously flows into the liquid cooling plate 4, thereby continuously reducing the temperature of the optical module 2.

[0044] The implementation principle of Example 1 is as follows: when the coolant flows through the liquid cooling plate 4, the diverter strips 9 in the liquid cooling plate 4 evenly disperse the coolant in the liquid cooling plate 4, so that the temperature of the contact surface between the liquid cooling plate 4 and the optical module 2 tends to be consistent. At the same time, the diverter strips 9 increase the contact area between the coolant and the liquid cooling plate 4, thereby improving the heat exchange efficiency between the coolant and the liquid cooling plate 4, thereby improving the heat exchange efficiency between the liquid cooling plate 4 and the optical module 2.

[0045] During the process of inserting the optical module 2 into the fiber cage 1, the insertion end of the optical module 2 first abuts against the guiding slope 8 of the liquid cooling plate 4. At this time, the liquid cooling plate 4 slides upward under the action of the reaction force pushed by the optical module 2 until the optical module 2 is completely inserted into the fiber cage 1.

[0046] During this process, the first elastic connecting tube 71 and the second elastic connecting tube 72 are deformed at the same time, and at this time, the restoring deformation force of the first elastic connecting tube 71 and the second elastic connecting tube 72 will press the liquid cooling plate 4 tightly against the optical module 2. The heat generated by the optical module 2 during operation is transferred to the liquid cooling plate 4 through heat transfer, and the heat on the liquid cooling plate 4 is also transferred to the coolant in the liquid cooling plate 4 through heat transfer.

[0047] The cooling liquid from the liquid inlet pipe 5 flows into the liquid outlet pipe 6 along the order of passing through the first elastic connecting pipe 71, the liquid cooling plate 4 and the second elastic connecting pipe 72, so that the low-temperature cooling liquid continuously flows into the liquid cooling plate 4, thereby continuously reducing the temperature of the optical module 2.

[0048] Example 2

[0049] refer to Figure 4 The difference between this embodiment and embodiment 1 is that the connecting pressure component 7 includes a liquid hose 73 for connecting the liquid cooling plate 4 and the liquid inlet pipe 5, and the liquid cooling plate 4 and the liquid outlet pipe 6. A square cross-section tube 74 with a square cross-section is welded on the liquid inlet pipe 5 and the liquid outlet pipe 6. The square cross-section tube 74 is sleeved on the liquid hose 73. The liquid hose 73 can be made of TPU material in the existing technology.

[0050] TPU material has high strength, cold resistance, high temperature resistance, wear resistance, oxidation resistance, non-toxic, colorless, odorless, and has high aging resistance, strong endurance and compression and distortion resistance. At the same time, it has high softness and is suitable for situations where the infusion time is long and the infusion rate is fast.

[0051] Reference Figure 4 、 Figure 5 and Figure 6 A limit frame 75 is welded on the top of the liquid cooling plate 4, and the limit frame 75 is sleeved on the square horizontal tube 74. There is a gap between the inner side walls of the limit frame 75 and the two sides of the square horizontal tube 74 in the vertical direction. A top plate 76 with a Z-shaped cross section is welded on the liquid inlet pipe 5 and the liquid outlet pipe 6 and located above the limit frame 75. A compression spring 77 is supported between the top plate 76 and the limit frame 75. A guide rod 10 is vertically slidably arranged on the top plate 76, and the compression spring 77 is sleeved on the guide rod 10.

[0052] Reference Figure 4 、 Figure 5 and Figure 6 A tube inclined groove 11 is provided on the square horizontal tube 74. The tube inclined groove 11 on the square horizontal tube 74 on the liquid inlet pipe 5 is arranged obliquely along the direction from the square horizontal tube 74 to the liquid cooling plate 4 toward the liquid outlet pipe 6. A locking shaft 12 is slidably arranged on the tube inclined groove 11 of the square horizontal tube 74. A pressure wheel 13 is coaxially sleeved on the locking shaft 12, and the pressure wheel 13 is located inside the square horizontal tube 74.

[0053] Reference Figure 4 、 Figure 5 and Figure 6 The pressure wheel 13 is used to press the liquid hose 73 against the inner wall of the square cross tube 74. A frame bevel 14 is provided on the limit frame 75 on the square cross tube 74 sleeved on the liquid inlet pipe 5. The frame bevel 14 is arranged obliquely along the direction from the square cross tube 74 to the liquid cooling plate 4 and away from the liquid outlet pipe 6. The locking shaft 12 slides in cooperation with the frame bevel 14 on the limit frame 75. The square cross tube 74 and the limit frame 75 on the liquid outlet pipe 6 are arranged symmetrically about the center line of the liquid cooling plate 4.

[0054] Under the elastic force of the compression spring 77, when the limit frame 75 drives the liquid cooling plate 4 to descend to the lowest position, the side wall of the frame bevel groove 14 on the limit frame 75 will squeeze the locking shaft 12. Since the limit frame 75 can only slide vertically under the restriction of the guide rod 10, the limit frame 75 that slides vertically downward will cause the locking shaft 12 to slide downward along the inclined direction of the tube bevel groove 11 under the action of the frame bevel groove 14.

[0055] The locking shaft 12 will drive the pinch wheel 13 to slide synchronously, and the pinch wheel 13 will squeeze the liquid hose 73 against the inner wall of the square cross tube 74 until the locking shaft 12 moves to the lowest end of the inclined tube chute 11. At this time, the liquid hose 73 is completely compressed and deformed by the pinch wheel 13 to achieve a self-sealing effect. The coolant cannot flow through the liquid hose 73, thereby achieving the effect of preventing the coolant from flowing through the liquid cooling plate 4 without the optical module 2 installed, which is beneficial to improving the utilization rate of the heat transfer of the coolant and reducing the energy consumption.

[0056] During the process of inserting the optical module 2 into the optical fiber cage 1, as the insertion end of the optical module 2 abuts the guiding inclined surface 8, the liquid cooling plate 4 drives the limit frame 75 to slide upward synchronously. During this process, the compression spring 77 is continuously compressed until the optical module 2 is completely inserted into the optical fiber cage 1. At this time, the restoring deformation force of the compression spring 77 will cause the liquid cooling plate 4 to press tightly against the optical module 2. In the process of the coolant flowing into and out of the liquid cooling plate 4 through the liquid hose 73, the liquid cooling plate 4 takes away the heat from the optical module 2 by heat transfer.

[0057] During the upward sliding movement of the liquid cooling plate 4, the locking shaft 12 drives the pinch wheel 13 to move to the highest inclined end of the tube chute 11. During this process, the liquid hose 73 is continuously separated from the pinch wheel 13 until the liquid hose 73 is completely separated from the pinch wheel 13. At this time, the coolant can flow into and out of the liquid cooling plate 4 through the liquid hose 73, and achieve a cooling effect on the optical module 2 through heat transfer.

[0058] The implementation principle of Example 2 is as follows: under the elastic force of the compression spring 77, when the limit frame 75 drives the liquid cooling plate 4 to descend to the lowest position, the side wall of the frame bevel groove 14 on the limit frame 75 will squeeze the locking shaft 12. Since the limit frame 75 can only slide vertically under the restriction of the guide rod 10, the limit frame 75 that slides vertically downward will cause the locking shaft 12 to slide downward along the inclined direction of the tube bevel groove 11 under the action of the frame bevel groove 14.

[0059] The locking shaft 12 will drive the pinch wheel 13 to slide synchronously, and the pinch wheel 13 will squeeze the liquid hose 73 against the inner wall of the square cross tube 74 until the locking shaft 12 moves to the lowest end of the inclined tube chute 11. At this time, the liquid hose 73 is completely compressed and deformed by the pinch wheel 13 to achieve a self-sealing effect. The coolant cannot flow through the liquid hose 73, thereby achieving the effect of preventing the coolant from flowing through the liquid cooling plate 4 without the optical module 2 installed, which is beneficial to improving the utilization rate of the heat transfer of the coolant and reducing the energy consumption.

[0060] During the process of inserting the optical module 2 into the optical fiber cage 1, as the insertion end of the optical module 2 abuts the guiding inclined surface 8, the liquid cooling plate 4 drives the limit frame 75 to slide upward synchronously. During this process, the compression spring 77 is continuously compressed until the optical module 2 is completely inserted into the optical fiber cage 1. At this time, the restoring deformation force of the compression spring 77 will cause the liquid cooling plate 4 to press tightly against the optical module 2. In the process of the coolant flowing into and out of the liquid cooling plate 4 through the liquid hose 73, the liquid cooling plate 4 takes away the heat from the optical module 2 by heat transfer.

[0061] During the upward sliding movement of the liquid cooling plate 4, the locking shaft 12 drives the pinch wheel 13 to move to the highest inclined end of the tube chute 11. During this process, the liquid hose 73 is continuously separated from the pinch wheel 13 until the liquid hose 73 is completely separated from the pinch wheel 13. At this time, the coolant can flow into and out of the liquid cooling plate 4 through the liquid hose 73, and achieve a cooling effect on the optical module 2 through heat transfer.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
