[0001] The invention relates to a liquid cooling and heat dissipation mechanism for an optical module. Background Art

[0002] With the growth of the Internet system and the increase of networked devices, the data information generated by the Internet is growing exponentially, which has led to the rapid development of optical communication technology with larger transmission bandwidth and capacity, lower transmission loss, stronger anti-electromagnetic interference ability and higher transmission quality. As a key component in the optical communication system, the optical module affects the transmission speed and quality of data. As the transmission rate of the optical module increases, its power also increases, inevitably generating a lot of heat. If this heat cannot be effectively discharged, it will directly affect the stability of the internal environment of the optical module, resulting in a decrease in the quality of the optical signal, and may even accelerate the aging of components and shorten the life of the optical module.

[0003] At present, in order to improve the cooling and heat dissipation effect of the optical module, a liquid-cooled optical module has appeared in the prior art. By setting a cooling circuit inside the optical module and connecting the optical module to the liquid cooling system, the coolant of the liquid cooling system can flow into the liquid-cooled optical module to cool and dissipate the heat. However, the existing liquid-cooled optical module has the following problems when used: the connection structure between the liquid-cooled optical module and the liquid cooling system is relatively complex, resulting in low connection efficiency between the liquid-cooled optical module and the liquid cooling system, and inconvenient use. Therefore, it is necessary to design a corresponding technical solution to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a liquid-cooled heat dissipation mechanism for an optical module, which has a reasonable structure. By integrating the male head of the connector assembly into the optical module body and connecting the female head of the connector assembly to the water distributor of the liquid cooling system, the liquid cooling system and the internal cooling circuit of the optical module can be automatically connected when the optical module is inserted, so as to realize the rapid connection between the optical module and the liquid cooling system, and then the optical module can be cooled and cooled, which has the advantage of being more convenient to use; and, by arranging a friction-reducing sealing ring, the friction force that needs to be overcome when the valve core and the valve sleeve are reset is reduced, so that the reset requirements of the valve core and the valve sleeve in the connector assembly can be met while reducing the elastic force of the reset spring.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is to design a liquid cooling and heat dissipation mechanism for an optical module, including an optical module body and a connector assembly; The joint assembly includes a liquid supply joint and a liquid return joint, each of which includes a male head and a female head, and the male head and the female head each have a front end as a butt end; The male head comprises a male head valve body, a valve core, a valve core return spring and a spring stopper arranged inside the male head valve body, the tail end of the male head valve body is connected to the optical module body, and the front end of the valve core is sleeved with a valve core sealing ring abutting against the inner surface of the male head valve body; The female head comprises a female head valve body, a valve stem, a valve sleeve and a valve sleeve return spring arranged inside the female head valve body, the tail end of the female head valve body is connected to a water distributor connector, and the front end of the valve stem is sleeved with a valve stem sealing ring abutting against the inner surface of the valve sleeve; The valve core sealing ring and the valve stem sealing ring are both friction-reducing sealing rings, which include a sealing ring body. The middle position of the sealing ring body has a waveform structure, which includes two semicircular peaks and a trough formed between the two semicircular peaks. There is an arc transition between the semicircular peaks and the sealing ring body.

[0006] Preferably, the valve sleeve is made of self-lubricating material.

[0007] Preferably, the material of the valve sleeve is PEEK.

[0008] Preferably, the inner surface of the male valve body and the inner surface of the female valve body are both provided with a friction-reducing coating.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0028] The technical solution specifically implemented in the present invention is: In a specific embodiment, Figures 1 to 7 As shown, the present invention provides a liquid cooling and heat dissipation mechanism for an optical module, comprising an optical module body 1 and a connector assembly; The connector assembly includes a liquid supply connector 2 and a liquid return connector 3, each of which includes a male connector 4 and a female connector 5, and the male connector 4 and the female connector 5 each have a front end as a butt end; The male connector 4 includes a male connector valve body 41, a valve core 42, a valve core return spring 43 and a spring stopper 44 arranged inside the male connector valve body 41, the tail end of the male connector valve body 41 is connected to the optical module body 1, and the front end of the valve core 42 is sleeved with a valve core sealing ring 45 abutting against the inner surface of the male connector valve body 41; The female head 5 comprises a female head valve body 51, a valve stem 52, a valve sleeve 53 and a valve sleeve return spring 54 arranged inside the female head valve body 51, the tail end of the female head valve body 51 is connected to a water distributor connector 55, and the front end of the valve stem 52 is sleeved with a valve stem sealing ring 56 abutting against the inner surface of the valve sleeve 53; The valve core sealing ring 45 and the valve stem sealing ring 56 are both friction-reducing sealing rings, which include a sealing ring body 6. The middle position of the sealing ring body 6 has a waveform structure, and the waveform structure includes two semicircular peaks 61 and a trough 62 formed between the two semicircular peaks 61. There is an arc transition 63 between the semicircular peaks 62 and the sealing ring body 6.

[0029] Adopt the above scheme: In the present invention, the female head 5 of the liquid supply connector 2 and the liquid return connector 3 is fixedly connected to the water distributor of the liquid cooling system of the network equipment through the water distributor connector 55 at the tail end. Specifically, an external thread can be provided on the water distributor connector 55 so that the water distributor connector 55 is fixedly connected to the water distributor by threaded matching. In the present invention, the tail ends of the male head 4 of the liquid supply connector 2 and the liquid return connector 3 are fixedly connected to the optical module body 1, so that the male head 4 of the liquid supply connector 2 and the liquid return connector 4 are respectively connected to the liquid inlet and the liquid outlet of the internal cooling circuit of the optical module body 1. When in use, the optical module body 1 is inserted into the optical cage of the network device. During the process, the optical module body 1 will drive the male head 4 to dock with the female head 5. When the optical module body 1 is inserted in place, the male head 4 and the female head 5 are docked. The locking structure in the optical cage cooperates with the original structure of the optical module body 1 to apply a tightening force to the optical module body 1 to tighten it. Therefore, there is no need to modify the original structure of the optical module body 1 before putting it into use, which saves design costs and maintains the original use of the optical module. The operation is simple and easy to use. During the docking process between the male connector 4 and the female connector 5, the front end of the male connector valve body 41 is inserted into the female connector valve body 51 from the front end of the female connector valve body 51, and the male connector valve body 41 pushes the valve sleeve 53 back and compresses the valve sleeve reset spring 54, while the valve stem 52 pushes the valve core 42 back and compresses the valve core reset spring 43, so that the internal flow channel of the male connector valve body 41 is connected with the internal flow channel of the female connector valve body 51, and then the water distributor of the liquid cooling system is connected with the internal cooling circuit of the optical module body 1 through the liquid supply connector 2 and the liquid return connector 3. When the optical module body 1 is pulled out of the optical cage of the network device, the optical module body 1 will drive the male connector 4 to disconnect from the female connector 5, so that the optical module body 1 is disconnected from the water distributor of the liquid cooling system, and during the disconnection process between the male connector and the female connector, the valve core 42 and the valve sleeve 53 are reset and intercept the cooling liquid under the action of the reset springs connected to each other.

[0030] When the optical module body 1 is in the plug-in state, the optical module body 1 is fastened by the locking structure of the optical cage, so that the male head 4 and the female head 5 are kept in the docking state. However, in order to meet the plug-in and pull-out requirements of the optical module, the locking structure of the optical cage will not apply too much fastening force to the optical module body 1. Since the valve core reset spring 43 and the valve sleeve reset spring 54 are both in a compressed state, there will be a risk of the male head 4 and the female head 5 being ejected and separated by the spring elastic force, and the optical module body 1 will also be ejected from the optical cage, affecting the normal use and operation of the equipment. In order to overcome the above problems, a reset spring with a smaller elastic force is adopted in the present invention. In order to reduce the elastic force of the reset spring, and in order to enable the valve core 42 and the valve sleeve 53 to be smoothly reset under the action of the reset spring, the method adopted by the present invention is to set a friction-reducing sealing ring to reduce the friction force that needs to be overcome when the valve core 42 and the valve sleeve 53 are reset, so that the reset requirements of the valve core 42 and the valve sleeve 53 can be met under the condition of reducing the elastic force of the reset spring.

[0031] In the present invention, by improving the structure of the valve core seal ring 45 and the valve stem seal ring 56, the friction of the seal ring can be effectively reduced, thereby reducing the friction that needs to be overcome when the valve core 42 and the valve sleeve 53 are reset. Specifically, taking the valve core seal ring 45 as an example, the friction calculation formula is: f=μ*Fn; where μ is the friction coefficient, and Fn is the positive pressure. In the application scenario of the present invention, the friction formula can be equivalent to: f=μ*K*X; where μ is the friction coefficient, K is the elastic coefficient of the sealing material, and X is the compression rate. The compression rate of the traditional O-ring applied to the present invention is 25%, and the compression rate of the valve core seal ring 45 in the present invention is 15%. The theoretical calculation of the friction force of the traditional O-ring is: f1=μ*K*X, and the theoretical calculation of the friction force of the valve core seal ring 45 in the present invention is: f2=μ*K*0.6X, from which it can be concluded that: 0.6*f1=f2. It can be seen that, compared with the traditional O-ring, the valve core sealing ring 45 of the present invention reduces the compression rate while ensuring a certain sealing performance by setting a corrugated structure, thereby reducing the friction of the sealing ring, so that the friction that needs to be overcome when the valve core 42 is reset is reduced, so that the reset requirement of the valve core 42 can be met while reducing the elastic force of the reset spring. Figure 8 and Fig. 9 , Figure 8 The displacement distance L of the valve core 42 drives the valve core sealing ring 45 to contact or separate from the front inner wall of the male valve body 41 during the displacement of the valve core 42. Fig. 9 yes Figure 8 From the comparison diagram of the friction force of the sealing ring in the displacement distance, it can be understood that during the resetting process of the valve core 42, compared with the traditional O-ring, the valve core sealing ring 45 in the present invention is provided with a corrugated structure, so that the contact between the valve core sealing ring 45 and the inner wall of the front end of the male valve body 41 is smoother, and the whole process of the contact and extrusion between the valve core sealing ring 45 and the male valve body will be lengthened, so that the compression amount of the valve core sealing ring 45 in the unit stroke is reduced, thereby making the process of the valve core sealing ring 45 being squeezed and compressed smoother, which is more conducive to the smooth resetting of the valve core 42.

[0032] In another specific embodiment, the valve sleeve 53 is made of a self-lubricating material, and preferably the material of the valve sleeve 53 is PEEK.

[0033] The above solution is adopted: by providing a valve sleeve 53 made of self-lubricating material to replace the traditional metal valve sleeve, the friction force that needs to be overcome when the valve sleeve 53 is reset is further reduced, which is conducive to further reducing the elastic force requirement of the valve sleeve reset spring 54.

[0034] In another specific embodiment, the inner surface of the male valve body 41 and the inner surface of the female valve body 51 are both provided with a friction-reducing coating, and preferably the friction-reducing coating is a DLC coating.

[0035] The above solution is adopted: by providing a friction-reducing coating, the friction force that needs to be overcome when the valve core 42 and the valve sleeve 53 are reset is further reduced, which is conducive to further reducing the elastic force requirements of the valve core reset spring 43 and the valve sleeve reset spring 54.

[0036] In another specific embodiment, Figure 3 and Figure 7 As shown, the tail end of the male valve body 41 is provided with an annular groove 46, and the spring stopper 44 is made of elastic material. The spring stopper 44 is engaged with the annular groove 46, and the spring stopper 44 is a conical structure with an outer diameter gradually decreasing from the tail end to the front end of the male valve body 41. Preferably, the material of the spring stopper 44 is PEEK.

[0037] The above scheme is adopted: the function of the spring stopper 55 in the present invention is the same as that of the traditional metal retaining ring, which is used to resist the valve core reset spring 43. However, due to the ultra-small size of the joint assembly in the present invention, its maximum outer diameter is only 5mm, and it is difficult to assemble using the traditional metal retaining ring, and the assembly of the traditional metal retaining ring has high requirements for the depth of the annular groove 46. The thickness of the tube wall of the valve body 41 in the present invention is thin, which is not conducive to the processing of the annular groove 46 with a deeper depth, resulting in difficulty in meeting the assembly requirements of the traditional metal retaining ring. Therefore, the present invention sets a spring stopper 44 made of elastic material to replace the traditional metal retaining ring. In addition, the spring stopper 44 is set as a conical structure in the present invention, so that when assembling the spring stopper 44, it can be smoothly pushed from the tail end of the male valve body 41 into the inside of the male valve body 41. When the spring stopper 44 is pushed into place, it is restored to its original state through its own elastic deformation and is clamped with the annular groove 46, so that the assembly is simpler and more efficient.

[0038] In another specific embodiment, Figure 1 As shown, the optical module liquid cooling heat dissipation mechanism also includes a connecting seat 7, the optical module body 1 is fixed to one side of the connecting seat 7, and the other side of the connecting seat 7 is symmetrically provided with two snap-in holes, and the tail ends of the two male valve bodies 41 are respectively snap-fitted and fixed to the two snap-in holes.

[0039] The above solution is adopted: the connection between the male valve body 41 and the optical module body 1 is realized by providing the connecting seat 7, and the original structure of the optical module body 1 is slightly changed, thereby reducing the modification cost.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
