Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical module heat dissipation, in particular to an elastic liquid cooling device for a plug-in optical module. BACKGROUND

[0002] An optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The sending end of the optical module converts electrical signals into optical signals, which are transmitted through an optical fiber. The receiving end then converts the optical signals back into electrical signals to achieve information transmission.

[0003] Currently, as the integration level of optical modules increases, the heat density of chips in the optical modules also increases. When the heat density of the chips is too high, it will cause heat concentration on the chips and make it difficult to dissipate heat, which can easily form a local high-temperature area in the optical module, seriously affecting the photoelectric performance of the optical module. Therefore, heat dissipation is particularly important.

[0004] A cold plate is disclosed in Chinese Patent No. CN219610420U, which includes a plate body and a floating pressure regulating chamber. The plate body has a cold plate flow channel for communicating with an external circulating cooling device, and the floating pressure regulating chamber is disposed inside the plate body.

[0005] In the above-mentioned technology, the cold plate is usually installed in a fixed manner. The cooling of the optical module is achieved through heat transfer after contacting the cold plate. However, since the optical module requires a plug-in design, the contact surface between the optical module and the cold plate will gradually generate a gap due to friction after long-term use. This will cause the heat transfer effect between the optical module and the cold plate to deteriorate, greatly affecting the heat dissipation effect of the optical module, and there are deficiencies. SUMMARY

[0009] By adopting the above technical scheme, when the optical module is inserted on the optical fiber cage, the communication pressure assembly makes the liquid cooling plate press tightly on the optical module, at the same time, the liquid inlet pipe and the liquid outlet pipe make the cooling liquid flow through the liquid cooling plate constantly, the liquid cooling plate removes the heat generated on the optical module by heat transfer, so that the temperature of the optical module is reduced, since the position of the liquid cooling plate can be changed and always closely contacts the optical module, the problem that the gap is generated between the optical module and the liquid cooling plate in the process of inserting and pulling is solved, so that the optical module can always maintain good cooling effect.

[0010] Optionally, the liquid cooling plate is provided with a guide slope at the end inserted to the optical module, the guide slope is inclined to the insertion end of the optical module along the direction from the liquid cooling plate to the optical module.

[0011] By adopting the above technical scheme, in the process of inserting the optical module, the insertion end of the optical module abuts against the guide slope on the liquid cooling plate, with the continuous insertion of the optical module, the liquid cooling plate is continuously lifted, so that the optical module can be smoothly inserted into the optical fiber cage.

[0015] By adopting the above technical scheme, in the process of inserting the optical module into the optical fiber cage, as the insertion end of the optical module abuts against the guide slope, the liquid cooling plate slides upward, and the first elastic connecting pipe and the second elastic connecting pipe simultaneously deform until the optical module is completely inserted into the optical fiber cage, at this time, the restoring deformation force of the first elastic connecting pipe and the second elastic connecting pipe tightly presses the liquid cooling plate on the optical module, and the cooling liquid can flow into and out of the liquid cooling plate through the first elastic connecting pipe and the second elastic connecting pipe, so that the optical module continuously cools down.

[0016] Optionally, the first elastic connecting pipe and the second elastic connecting pipe are both in a wave shape in cross section.

[0017] By adopting the above technical scheme, the restoring deformation force of the first elastic connecting pipe and the second elastic connecting pipe is enhanced, which is beneficial to improve the pressing effect of the liquid cooling plate on the optical module and reduce the possibility of generating a gap between the liquid cooling plate and the optical module.

[0019] By adopting the above technical scheme, in the process of inserting the optical module into the optical fiber cage, as the insertion end of the optical module abuts against the guide slope, the liquid cooling plate drives the limiting frame to synchronously slide upward, and the compression springs are compressed until the optical module is completely inserted into the optical fiber cage, at this time, the restoring deformation force of the compression springs tightly presses the liquid cooling plate on the optical module, and in the process of the cooling liquid flowing into and out of the liquid cooling plate through the liquid passing hose, the liquid cooling plate takes away the heat on the optical module by heat transfer, so that the temperature of the optical module continuously decreases.

[0020] Optionally, a guide rod is vertically and slidably arranged on the top plate, and the compression spring is sleeved on the guide rod.

[0021] By adopting the technical scheme, the possibility that the compression spring is accidentally separated from the top plate and the limiting frame is reduced.

[0022] Optionally, a tube inclined groove is formed in the square horizontal pipe, the tube inclined groove on the square horizontal pipe on the liquid inlet pipe is arranged to be inclined towards the liquid outlet pipe in the direction from the square horizontal pipe to the liquid cooling plate, a locking shaft is slidingly arranged on the tube inclined groove of the square horizontal pipe, a compression wheel is coaxially sleeved on the locking shaft, the compression wheel is used to compress the liquid passing hose on the inner side wall of the square horizontal pipe, a frame inclined groove is formed in the limiting frame on the square horizontal pipe on the liquid inlet pipe, the frame inclined groove is arranged to be inclined away from the liquid outlet pipe in the direction from the square horizontal pipe to the liquid cooling plate, and the locking shaft is slidingly matched with the frame inclined groove on the limiting frame.

[0023] By adopting the technical scheme, under the elastic force of the compression spring, the limiting frame drives the liquid cooling plate to descend, in this process, the sidewall of the frame inclined groove on the limiting frame extrudes the locking shaft, since the limiting frame can only vertically slide under the limiting action of the guide rod, the locking shaft slides downward along the inclined direction of the tube inclined groove, and the locking shaft drives the compression wheel to synchronously slide, the compression wheel extrudes the liquid passing hose, until the locking shaft moves to the lowest end of the inclination of the tube inclined groove, at this time, the liquid passing hose is completely compressed and closed by the compression wheel, and the cooling liquid cannot flow through the liquid passing hose, so that the effect that the cooling liquid cannot flow through the liquid cooling plate without the optical module is realized, and for the liquid cooling plate with the optical module, at this time, the locking shaft drives the compression wheel to move to the highest end of the inclination of the tube inclined groove, at this time, the liquid passing hose is not extruded and deformed by the compression wheel, and the cooling liquid can flow into and out of the liquid cooling plate through the liquid passing hose, so that the cooling effect of the optical module is realized, thereby the utilization rate of heat transfer of the cooling liquid is improved, and the energy consumption is reduced.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. When the optical module is inserted on the optical fiber cage, the liquid cooling plate is compressed on the optical module by the communication and pressure assembly, at the same time, the liquid inlet pipe and the liquid outlet pipe make the cooling liquid continuously flow through the liquid cooling plate through the communication and pressure assembly, the liquid cooling plate removes the heat generated on the optical module by heat transfer, so that the temperature of the optical module is reduced, since the position of the liquid cooling plate can be changed and always closely contacts the optical module, the problem that the gap is generated between the optical module and the liquid cooling plate in the plugging and unplugging friction process is solved, so that the optical module can always maintain good cooling effect;

[0026] 2. In the process of inserting the optical module into the optical fiber cage, as the insertion end of the optical module abuts the guide slope, the liquid cooling plate slides upward, and the first and second elastic connecting tubes simultaneously deform until the optical module is completely inserted into the optical fiber cage. At this time, the restoring deformation force of the first and second elastic connecting tubes tightly presses the liquid cooling plate on the optical module, and the cooling liquid can flow into and out of the liquid cooling plate through the first and second elastic connecting tubes, thereby continuously cooling the optical module;

[0027] 3. Under the elastic force of the compression spring, the limiting frame drives the liquid cooling plate to descend. In this process, the sidewall of the frame inclined groove on the limiting frame will press the locking shaft. Since the limiting 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 compression wheel to slide synchronously. The compression wheel will extrude the liquid conveying hose until the locking shaft moves to the lowest end of the tube inclined groove. At this time, the liquid conveying hose is completely compressed and closed by the compression wheel, and the cooling liquid cannot flow through the liquid conveying hose. In this way, the effect that the cooling liquid cannot flow through the liquid cooling plate without the optical module is achieved. For the liquid cooling plate with the optical module, the locking shaft drives the compression wheel to move to the highest end of the tube inclined groove at this time. At this time, the liquid conveying hose is not extruded and deformed by the compression wheel, and the cooling liquid can flow into and out of the liquid cooling plate through the liquid conveying hose, thereby achieving the cooling effect of the optical module. In this way, it is beneficial to improve the utilization rate of heat transfer of the cooling liquid and reduce the consumption of energy. BRIEF DESCRIPTION OF DRAWINGS

[0042] During the flowing of the cooling liquid through the liquid cooling plate 4, the shunt bar 9 in the liquid cooling plate 4 uniformly disperses the cooling liquid 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, meanwhile, the shunt bar 9 increases the contact area between the cooling liquid and the liquid cooling plate 4, improves the heat exchange efficiency between the cooling liquid and the liquid cooling plate 4, and thus improves the heat exchange efficiency between the liquid cooling plate 4 and the optical module 2.

[0050] In this process, the first elastic connecting pipe 71 and the second elastic connecting pipe 72 are deformed at the same time, and at this time, the restoring deformation force of the first elastic connecting pipe 71 and the second elastic connecting pipe 72 tightly presses the liquid cooling plate 4 on the optical module 2, and the heat generated by the optical module 2 during operation is transmitted to the liquid cooling plate 4 by heat transfer, and the heat on the liquid cooling plate 4 is also transmitted to the cooling liquid in the liquid cooling plate 4 by heat transfer.
