Description

Technical Field

[0001] This utility model relates to the field of optical module heat dissipation technology, and in particular to a heat exchange structure. Background Technology

[0002] Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The transmitting end of an optical module converts electrical signals into optical signals, and the receiving end converts optical signals back into electrical signals. Currently, with the rapid development of artificial intelligence demands, the data rate requirements for optical modules, as essential network transmission components for AI interaction, are increasing dramatically, leading to a rapid rise in their overall power consumption. Currently, heat dissipation of optical modules has become a major challenge in switch thermal design.

[0003] Currently, the main heat dissipation method for optical modules on the market is to bond a cold plate to the heat-generating structure of the optical module. This bonding is achieved primarily through a spring-loaded or sheet-like elastic structure after the heat source is inserted, allowing heat transfer between the cold plate and the heat source. However, existing technologies cannot guarantee that every optical module connected to the system will have sufficient contact and heat dissipation with the cold plate, resulting in inadequate heat dissipation. Furthermore, existing technologies are complex in construction, inconvenient to use, and lack sufficient fatigue resistance of the elastic structure, leading to situations where the cold plate and optical module cannot maintain a tight bond after prolonged use.

[0004] Given the shortcomings of the existing technologies, there is an urgent need to design a heat exchange structure to solve the problems existing in the current technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a heat exchange structure that improves the smoothness of the optical module insertion process, reduces the obstruction during the insertion process, enhances the user experience, and improves the technical problem of poor heat dissipation of optical modules in existing related technical solutions.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A heat exchange structure includes a heat exchange plate, an optical module cage, and a driving component. The optical module cage is fitted onto the surface of the heat exchange plate and has a slot for installing an optical module. A notch is provided on the side of the slot facing the heat exchange plate. The driving component is connected to the heat exchange plate. When the optical module is inserted into the slot and pushes against the heat exchange plate through the notch, the driving component can drive the heat exchange plate to translate along the axial direction of the notch.

[0008] Preferably, the driving component includes an eccentric shaft, and the eccentric shaft is provided on both sides of the heat exchange plate along the insertion direction of the optical module. Each eccentric shaft includes a fixed part and a rotating part. The fixed part is fixedly disposed, and the rotating part is connected to the heat exchange plate and is rotatably disposed around the axis of the fixed part. The axis of the fixed part and the axis of the rotating part on the same eccentric shaft are offset and are both parallel to the opening end face of the notch. When the optical module pushes the heat exchange plate, the two rotating parts rotate synchronously to drive the two ends of the heat exchange plate to swing synchronously.

[0009] Preferably, the eccentric shaft has a flow-through hole that passes through the fixed part and the rotating part, and the flow-through hole is connected to the port of the heat exchange plate, so that the heat exchange medium can flow through one of the flow-through holes and one of the ports to the other flow-through hole and the other port.

[0010] Preferably, along the horizontal direction perpendicular to the insertion direction of the optical module, the heat exchange structure includes at least two optical module cages arranged side by side and the heat exchange plate, with each optical module cage corresponding to one of the heat exchange plates, and each heat exchange plate having an eccentric shaft on both sides.

[0011] Preferably, along the insertion direction of the optical module, the heat exchange structure further includes a splitter disposed on both sides of the optical module cage, and the eccentric shafts located on the same side are connected in parallel through the splitter. The splitter has a collection groove that communicates with the flow hole.

[0012] Preferably, the flow divider includes multiple flow divider modules connected in series, each flow divider module being disposed one-to-one with the heat exchange plate. Each flow divider module has a sub-flow collector, and multiple sub-flow collectors are connected in series to form the flow collector.

[0013] Preferably, the eccentric shafts are arranged side by side on both sides of the heat exchange plate; or, the eccentric shafts are arranged opposite each other on both sides of the heat exchange plate.

[0014] Preferably, the heat exchange structure further includes an elastic element disposed on the heat exchange plate and used to provide elastic force to the heat exchange plate along the axial direction of the notch.

[0015] Preferably, the elastic element includes at least two elastic connecting portions, which are symmetrically connected to the heat exchange plate with the axial direction of the notch as the center.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a heat exchange structure, which includes a heat exchange plate, an optical module cage, and a driving component. When the optical module is inserted into the slot, the optical module can contact the bottom of the heat exchange plate through the notch and apply a pushing force to the heat exchange plate away from the direction of the optical module. At the same time, the optical module can also apply a pushing force to the heat exchange plate along the insertion direction of the optical module. Under the combined action of the two forces, the driving component can drive the heat exchange plate to move in a translational motion along the axis of the notch, ensuring that the two sides of the heat exchange plate remain flush during the movement and that no tilting occurs. This improves the smoothness of the optical module insertion process, greatly reduces the feeling of obstruction during insertion, enhances the user experience, and ensures good heat dissipation of the optical module.

[0038] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] Combination Figures 1 to 4 As shown, this embodiment provides a heat exchange structure, which includes a heat exchange plate 1, an optical module cage 2, and a driving component. The optical module cage 2 is fitted onto the surface of the heat exchange plate 1, and the optical module cage 2 has a slot 21 for installing the optical module. A notch 22 is opened on the side of the slot 21 facing the heat exchange plate 1. The driving component is connected to the heat exchange plate 1. When the optical module is inserted into the slot 21 and pushes the heat exchange plate 1 through the notch 22, the driving component can drive the heat exchange plate 1 to translate along the axial direction of the notch 22 (see reference). Figure 1 (As shown by the unidirectional arrow on the X-axis).

[0041] The optical module cage 2 is laid flat and has a cuboid structure. A cuboid slot 21, adapted to the shape of the optical module, is provided inside the cage 2. A notch 22 is provided at the top of the cage 2, and a heat exchange plate 1 is attached to the top surface of the cage 2. (Reference) Figure 4 As shown, the driving component includes an eccentric shaft 31, and eccentric shafts 31 are provided on both sides of the heat exchange plate 1 along the insertion direction of the optical module. Each eccentric shaft 31 includes a fixed part 311 and a rotating part 312. The fixed part 311 is fixedly installed, and the rotating part 312 is connected to the heat exchange plate 1 and is rotatably installed around the axis of the fixed part. The axis of the fixed part 311 and the axis of the rotating part 312 on the same eccentric shaft 31 are offset and are both parallel to the opening end face of the notch 22, that is, the axis of the fixed part 311 and the axis of the rotating part 312 are both parallel to the horizontal plane.

[0042] With the above configuration, when the optical module is inserted into the slot 21, the optical module can contact the bottom of the heat exchange plate 1 through the notch 22 and apply a pushing force to the heat exchange plate 1 away from the direction of the optical module. At the same time, the optical module can also apply a pushing force to the heat exchange plate 1 along the direction of insertion of the optical module. Under the combined action of the two forces, the heat exchange plate 1 can drive the rotating parts 312 on both sides to rotate synchronously around the axis of the fixed part 311, thereby driving the two ends of the heat exchange plate 1 to swing synchronously. This allows the heat exchange plate 1 to perform translational movements along the direction of insertion of the optical module and along the direction away from the optical module at the same time, ensuring that the two sides of the heat exchange plate 1 remain aligned during the movement and that no tilting occurs. This improves the smoothness of the optical module insertion process, greatly reduces the obstruction during insertion, and enhances the user experience. In addition, compared with the elastic structures such as springs used in existing related technologies, the setting of the eccentric shaft 31 can reduce the height of the heat exchange plate 1 (i.e., the axial direction parallel to the notch 22, see reference). Figure 3The space occupied by the heat exchange structure (as shown by the Z-axis) can be utilized to reduce the height installation space requirement of the heat exchange structure by taking advantage of the horizontal direction, so that it can be assembled and used in narrow environments, thereby greatly improving the flexibility of the heat exchange structure.

[0043] To ensure the stability of the translational movement of the heat exchange plate 1, the radial dimension and axial length of the eccentric shafts 31 on both sides of the heat exchange plate 1, the misalignment distance between the axis of the fixed part 311 and the axis of the rotating part 312 are all equal, so that when the heat exchange plate 1 is in the initial position, the bottom surface of the heat exchange plate 1 is parallel to the horizontal plane and closely attached to the top surface of the optical module cage 2; when the optical module is inserted, both sides of the heat exchange plate 1 can also move with the same angular velocity and arc length.

[0044] In this embodiment, the eccentric shaft 31 has a flow hole 313 that passes through the fixed part 311 and the rotating part 312. The flow hole 313 is connected to the port of the heat exchange plate 1, so that the heat exchange medium can flow from one flow hole 313 and one port to another flow hole 313 and another port. This allows the eccentric shaft 31 to also have the function of transmitting the heat exchange medium, avoiding the need for additional liquid nozzles, making the overall structure simpler and saving manufacturing costs.

[0045] It should be noted that in this embodiment, the heat exchange medium is a refrigerant liquid, such as water or ethylene glycol, to dissipate heat and cool the optical module, thereby extending its service life. Of course, in other parallel embodiments, in colder regions, this heat exchange structure can also heat the optical module by introducing a heat exchange medium with a higher temperature into the heat exchange plate 1, raising the module's temperature and preventing damage from excessively low temperatures. Therefore, this invention does not limit the type of heat exchange medium, as long as it ensures the optical module remains within a suitable operating temperature range.

[0046] Furthermore, this invention does not limit the number of optical module cages 2 provided. Exemplarily, in this embodiment, six optical module cages 2 are provided, arranged horizontally perpendicular to the insertion direction of the optical module (see reference). Figure 3 As shown on the Y-axis, six optical module cages 2 are arranged side by side and closely attached. Correspondingly, this embodiment sets six heat exchange plates 1 (only some heat exchange plates 1 are shown in the figure). The heat exchange plates 1 are arranged one-to-one with the optical module cages 2, and each heat exchange plate 1 has the aforementioned eccentric shaft 31 on both sides. This allows the heat exchange structure to be divided into multiple independently set heat exchange modules, which is convenient to use. Moreover, when the eccentric shaft 31 on one of the heat exchange plates 1 fails mechanically and cannot be used, it will not affect the heat exchange function of the optical modules inserted into the other optical module cages 2, thus reducing the scrap rate of the heat exchange structure.

[0047] Furthermore, the heat exchange structure provided in this embodiment also includes a flow divider 4. Along the insertion direction of the optical module, the heat exchange structure also includes flow dividers 4 disposed on both sides of the optical module cage 2. The eccentric shaft 31 located on the same side is connected in parallel through the flow dividers 4. The flow divider 4 has a collection groove that communicates with the flow hole 313. It can be understood that the heat exchange medium selects one of the flow dividers 4 to enter the heat exchange structure. Utilizing the uniform flow distribution effect of the flow divider 4, the heat exchange medium is evenly distributed into multiple streams that enter each heat exchange plate 1, thereby achieving uniform heat dissipation and cooling of multiple optical modules simultaneously, thus avoiding the phenomenon of high temperature in local areas. At the same time, after passing through the heat exchange plate 1, the multiple streams will converge through the eccentric shaft 31 into another flow divider 4 and be discharged outward together through the collection groove, avoiding accumulation in the heat exchange plate 1 and ensuring smooth flow of the heat exchange medium in multiple heat exchange plates 1.

[0048] Furthermore, in this embodiment, the eccentric shafts 31 are arranged side by side on both sides of the heat exchange plate 1, referring to... Figure 4 As shown, the horizontal cross-sectional shape of the heat exchange plate 1 is Z-shaped, meaning that two protrusions 11 extend from both sides of the heat exchange plate 1. Each protrusion 11 has a connecting hole 111, which communicates with the heat exchange channel 12 within the heat exchange plate 1. The two rotating parts 312 of the two eccentric shafts 31 are correspondingly inserted into the two connecting holes 111 and can be fixed by welding, threaded connection, or snap-fit, thus achieving a fixed connection between the heat exchange plate 1 and the rotating parts 312 of the eccentric shafts 31. This increases the compactness of the connection between the eccentric shafts 31 and the heat exchange plate 1. In this embodiment, when the optical module is inserted into the slot 21, the direction of translational movement of the heat exchange plate 1 on the horizontal plane is parallel to the insertion direction of the optical module.

[0049] Specifically, in order to achieve parallel connection between the flow divider 4 and multiple heat exchange plates 1, the flow divider 4 in this embodiment includes multiple flow divider modules 41 connected in series. The flow divider modules 41 are arranged one-to-one with the heat exchange plates 1. In this embodiment, the horizontal cross-sectional shape of the flow divider module 41 is L-shaped, including a flow collecting part 411 and a flow dividing part 412. The flow collecting part 411 extends horizontally and perpendicular to the direction in which the optical module is inserted. The flow dividing part 412 is connected to one end of the flow collecting part 411 and is parallel to the direction in which the optical module is inserted. The flow dividing part 412 is also connected to the fixing part 311 of the corresponding eccentric shaft 31. In addition, the flow distribution module 41 has L-shaped sub-collecting channels, and multiple sub-collecting channels are connected in series to form a collecting channel. This allows the portion of the sub-collecting channel in the flow distribution section 412 to be directly connected to the flow passage 313 in the eccentric shaft 31, while the portion in the collecting section 411 is connected in series with the sub-collecting channels in other flow distribution modules 41. This ensures unobstructed flow path of the heat exchange medium and avoids uneven flow or dead zones.

[0050] It is understood that in this embodiment, multiple flow distribution modules 41 are connected in series through a flow collection section 411. The end of the flow collection section 411 facing adjacent flow collection sections 411 is provided with a connector 42, which is inserted into the corresponding sub-flow collection groove. The connector 42 may be threaded to achieve a series and sealed connection between two adjacent flow distribution modules 41 through a threaded connection with the sub-flow collection groove. Alternatively, the connector 42 may be inserted into the sub-flow collection groove via an interference fit, or it may be inserted into the sub-flow collection groove via a snap-fit. This invention is not limited to any particular method, as long as it ensures that the heat exchange medium does not leak from the flow distributor 4. For example, in other parallel embodiments, a sealing ring may be fitted onto the connector 42 to enhance the sealing performance of the flow distributor 4.

[0051] Optionally, in this embodiment, the heat exchange structure further includes an elastic element 5, which is disposed on the heat exchange plate 1 and is used to provide elastic force to the heat exchange plate 1 along the axial direction of the notch 22. Exemplarily, the heat exchange structure provided in this embodiment also includes a top cover 6, which is flat and covers the top surface of the plurality of heat exchange plates 1. A plurality of elastic elements 5 are fixedly connected to the bottom of the top cover 6. When the optical module is inserted into the optical module cage 2, causing the heat exchange plate 1 to move upward along the axial direction of the notch 22, the elastic element 5 deforms and has an elastic pre-tightening force, providing elastic force to the heat exchange plate 1 to move closer to the optical module cage 2. This ensures that the heat exchange plate 1 is always tightly fitted with the optical module located inside the optical module cage 2, making the heat exchange plate 1 more stable and thus ensuring the heat exchange effect between the heat exchange plate 1 and the optical module.

[0052] The elastic element 5 includes at least two elastic connecting parts, which are symmetrically connected to the heat exchange plate 1 with the axis of the notch 22 as the center, so that both sides of the heat exchange plate 1 are subjected to uniform elastic force, further ensuring the tightness of the contact surface between the heat exchange plate 1 and the optical module. Preferably, in this embodiment, the elastic element 5 is an arched spring sheet, with its two ends abutting and connecting to the two sides of the heat exchange plate 1, and its top end fixedly connected to the top cover 6. The spring sheet is preferably made of metal to provide an appropriate amount of elastic force to the heat exchange plate 1.

[0053] Optionally, in this embodiment, the top of the heat exchange plate 1 has a limiting groove 13, and the two sides of the spring sheet abut against the side wall of the limiting groove 13 respectively, so as to reduce the sliding phenomenon between the elastic connection part and the heat exchange plate 1, so that the two ends of the spring sheet can be fixed with the heat exchange plate 1, and ensure that the spring sheet can generate sufficient deformation to provide sufficient elastic force for the heat exchange plate 1.

[0054] Example 2

[0055] Combination Figures 5 to 8 As shown, the heat exchange structure provided in this embodiment differs from the heat exchange structure provided in Embodiment 1 in that:

[0056] In this embodiment, reference Figure 7 As shown, two eccentric shafts 31 located on the same heat exchange plate 1 are arranged opposite each other, so that when the optical module is inserted into the optical module cage 2, the heat exchange plate 1 can translate horizontally in a direction perpendicular to the insertion of the optical module. This installation method of the eccentric shafts 31 is suitable for situations where there is limited space for installation along the direction of parallel arrangement of optical modules. Thus, the space occupancy rate can be reduced by decreasing the width of the heat exchange plate 1 and the optical module cage 2, thereby ensuring that a sufficient number of optical module cages 2 can be installed in the heat exchange structure to ensure the information processing capability of the communication switching equipment.

[0057] Optionally, in this embodiment, based on the installation feature of the eccentric shafts 31 on the heat exchange plate 1 being arranged opposite each other, the construction of the distributor 4 can be simplified. For example, the distributor 4 is straight and includes an upper cover and a lower cover (wherein the lower cover has milled flow channels) that can be sealed and fastened together, to replace the modularly arranged distributor 4 in embodiment one. The distributor 4 is rotatably connected to multiple rotating parts 312 of multiple eccentric shafts 31 on the same side, so that the distributor 4 in this embodiment has a simple construction and lower manufacturing cost.
