Figure 1-Figure 3 As shown, the radiator fastening structure includes a first fastening member 1 and a second fastening member 2, which are fastened together via side panels to form a housing for accommodating the radiator 4. The radiator fastening structure of this embodiment, formed by the upper and lower fastening connections of the first fastening member 1 and the second fastening member 2, forms an integral structure that wraps around the outside of the radiator 4. This provides better mechanical support, preventing the radiator 4 from shifting or loosening when subjected to external impact or vibration, thereby ensuring its stability and reliability. Furthermore, the integral wrapping design of the radiator fastening structure allows for overall movement and adjustment according to different heat dissipation requirements, making it suitable for a variety of different devices and applications.

[0052] The first fastener 1 is a rectangular shell structure with an opening facing downward, and a first snap-fit ​​portion 16 is provided on each of the four sides of the first fastener 1. The second fastener 2 is a rectangular shell structure with an opening facing upward, and a first snap-fit ​​portion 24 is provided on each of the four sides of the second fastener 2. When the first fastener 1 and the second fastener 2 are fastened together, the first snap-fit ​​portion 16 of the first fastener 1 and the first snap-fit ​​portion 24 of the second fastener 2 are fastened together in a one-to-one correspondence, forming a storage space for the radiator 4 between the first fastener 1 and the second fastener 2. The radiator fastening structure adopts the above-mentioned fastening connection method, which allows for installation or removal without tools, making maintenance and replacement convenient. The first fastener 1 is also provided with a second snap-fit ​​portion 17 on both sides along the length direction. The second snap-fit ​​portion 17 is used to fasten with the shielding cage 3, facilitating the installation or removal of the radiator fastening structure and the shielding cage 3, making installation easier.

[0053] like Figure 1 and Figure 2 As shown, the first fastening component 1 includes a top plate 11, a first upper side plate 12, a second upper side plate 13, a third upper side plate 14, and a fourth upper side plate 15. The first upper side plate 12 and the third upper side plate 14 are located on one side of the top plate 11 along the length direction (i.e., the same side), and the second upper side plate 13 and the fourth upper side plate 15 are located on the other side of the top plate 11 along the length direction (i.e., the same other side). The first upper side plate 12 and the third upper side plate 14 are arranged on one side of the top plate 11 along the width direction, and the second upper side plate 13 and the fourth upper side plate 15 are arranged on the other side of the top plate 11 along the width direction. The first upper side plate 12, the second upper side plate 13, the third upper side plate 14, and the fourth upper side plate 15 are vertically connected to the top plate 11, and together form a rectangular shell structure with an opening downward.

[0054] like Figure 1As shown, the second fastening component 2 includes a base plate 21 and first and second lower side plates 22, 23 located on either side of the base plate 21 along its length. The first and second lower side plates 22, 23 are perpendicularly connected to the base plate 21, together forming a rectangular housing structure with an upward opening. The rectangular housing structure formed by the second fastening component 2 is substantially the same size as the rectangular housing structure formed by the first fastening component 1.

[0055] like Figure 1 and Figure 2 As shown, the first upper side plate 12 and the second upper side plate 13 are both provided with a first buckle portion 16. Figure 1 As shown, both the first lower side panel 22 and the second lower side panel 23 are provided with a first snap-fit ​​portion 24. The first fastening member 1 and the second fastening member 2 are connected by the first snap-fit ​​portion 16 and the first snap-fit ​​portion 24. Multiple first snap-fit ​​portions 16 and 24 are provided, respectively. The specific number of first snap-fit ​​portions 16 and first snap-fit ​​portions 24 is determined based on actual needs to ensure secure installation and easy removal. To facilitate installation and removal, multiple first snap-fit ​​portions 16 and multiple first snap-fit ​​portions 24 are spaced apart along the length of the side panels to improve the stability of the connection.

[0056] The first upper panel 12 and the first lower panel 22 are positioned in the same width direction, the second upper panel 13 and the second lower panel 23 are positioned in the same width direction, and the number of first snap portions 16 and first engaging portions 24 are the same and their positions correspond to each other. When the first fastening member 1 and the second fastening member 2 are connected, the top panel 11 is positioned above the bottom panel 21, and the first upper panel 12 and the first lower panel 22, as well as the second upper panel 13 and the second lower panel 23, are fastened together by the corresponding first snap portions 16 and first engaging portions 24, respectively, to form a storage space for the radiator 4.

[0057] In this embodiment, the first snap-fit ​​portion 16 is a snap-fit ​​hole, which can be triangular, rectangular, polygonal, or circular. The first engaging portion 24 is a protrusion protruding toward the outside of the corresponding side panel, which can be triangular, rectangular, polygonal, or circular. The first engaging portion 24 is snap-fitted to the first snap-fit ​​portion 16, and the first snap-fit ​​portion 24 is located in the snap-fit ​​hole of the first snap-fit ​​portion 16. When the first fastening member 1 and the second fastening member 2 are connected, the first upper side panel 12 is located outside the first lower side panel 22, and the second upper side panel 13 is located outside the second lower side panel 23. This improves the stability of the connection and prevents the first snap-fit ​​portion 24 and the first snap-fit ​​portion 16 from disengaging.

[0058] In another embodiment, the first buckle portion 16 can be set as a protrusion, the first locking portion 24 can be set as a locking hole, the first upper side plate 12 is located on the inner side of the first lower side plate 22, and the second upper side plate 13 is located on the inner side of the second lower side plate 23.

[0059] In another embodiment, one of the first buckle portion 16 and the first engaging portion 24 is configured as a locking hole, and the other is configured as a hanging ear or a hook.

[0060] like Figure 1 and Figure 2 As shown, a second snap-fit ​​portion 17 is provided on each of the third upper side plate 14 and the fourth upper side plate 15. The second snap-fit ​​portion 17 is used to snap-fit ​​with the shielding cage 3, thereby fixing the heat sink snap-fit ​​structure within the shielding cage 3. This ensures that the heat sink 4 within the heat sink snap-fit ​​structure and the optical module 5 within the shielding cage 3 are relatively fixed in position, achieving good heat dissipation and temperature reduction.

[0061] The second buckle portion 17 is provided with a plurality of, and the specific number of the second buckle portion 17 is specifically set according to actual needs, so as to achieve the purpose of being easy to install firmly and easy to disassemble. In order to facilitate installation and disassembly, the plurality of second buckle portions 17 are spaced apart along the length direction of the side plate to improve the stability of the connection.

[0062] In this embodiment, the second latching portion 17 is a latching hole, which can be triangular, rectangular, polygonal, or circular. Correspondingly, a protrusion or a lug is provided on the shielding cage 3 to engage with the latching hole. The protrusion can be triangular, rectangular, polygonal, or circular. In another embodiment, the second latching portion 17 can be configured as a protrusion or a lug, with the corresponding latching hole provided on the shielding cage 3.

[0063] It should be noted that the first upper side panel 12, the first lower side panel 22, the second upper side panel 13, the second lower side panel 23, the third upper side panel 14 and the fourth upper side panel 15 can be provided with one or more, and each side panel can be provided with one or more first snap-fitting parts 16, first clamping parts 24 and second snap-fitting parts 17. Among them, the number of the first upper side panels 12 and the first lower side panels 22 are the same and their positions correspond one to one. The number of the first snap-fitting parts 16 provided on each first upper side panel 12 and the number of the first clamping parts 24 provided on each first lower side panel 22 are the same and their positions correspond to each other, so as to ensure the reliability of the connection. The number of the second upper side panels 13 and the second lower side panels 23 are the same and their positions correspond one to one. The number of the first snap-fitting parts 16 provided on each second upper side panel 13 and the number of the first clamping parts 24 provided on each second lower side panel 23 are the same and their positions correspond to each other, so as to ensure the reliability of the connection.

[0064] When multiple third upper panels 14 and fourth upper panels 15 are provided, the multiple third upper panels 14 are spaced apart by the first upper panel 12, and the multiple fourth upper panels 15 are spaced apart by the second upper panel 13. That is, a first upper panel 12 is provided between two adjacent third upper panels 14, and a second upper panel 13 is provided between two adjacent fourth upper panels 15. This disperses the connection points between the heat sink fastening structure and the shielding cage 3, improving connection stability. A gap may be provided between the first upper panel 12 and the third upper panel 14, or the structure may be integrally formed (i.e., without a gap).

[0065] In one embodiment, the first upper side panel 12 and the first lower side panel 22 are one, the second upper side panel 13 and the second lower side panel 23 are three, and the third upper side panel 14 and the fourth upper side panel 15 are two. The two third upper side panels 14 are located on either side of the first upper side panel 12, and the two fourth upper side panels 15 and the three second upper side panels 13 are arranged alternately, with the second upper side panels 13 being the outermost.

[0066] In this application, "a plurality" refers to two or more. The lengths of the third upper side plate 14 and the fourth upper side plate 15 can be set according to actual needs and can be greater than or equal to the lengths of the first upper side plate 12 and the second upper side plate 13.

[0067] like Figure 1 and Figure 2 As shown, the first fastening member 1 further includes a fifth upper side plate 18 and a sixth upper side plate 19 located on both sides of the top plate 11 in the width direction, and the first buckle portion 16 is provided on each of the fifth upper side plate 18 and the sixth upper side plate 19. Figure 1 and Figure 2 As shown, the second fastening member 2 also includes a third lower side plate 25 and a fourth lower side plate 26 located on both sides of the bottom plate 21 in the width direction, and the third lower side plate 25 and the fourth lower side plate 26 are both provided with a first snap-fit ​​portion 24. The first snap-fit ​​portion 16 and the first snap-fit ​​portion 24 have the same structure as the above-mentioned embodiment and are not described in detail. Among them, the fifth upper side plate 18 and the third lower side plate 25 have the same position in the length direction, and the sixth upper side plate 19 and the fourth lower side plate 26 have the same position in the length direction. The number of the first snap-fit ​​portion 16 and the first snap-fit ​​portion 24 are the same and the positions are arranged in a one-to-one correspondence. As shown Figure 4 and Figure 5 As shown, the fifth upper side plate 18 and the third lower side plate 25 are respectively arranged in the middle position of the top plate 11 and the bottom plate 21. After the two are connected up and down, the connecting blocks and joints on both sides of the radiator 4 can extend from both sides and be connected to the liquid storage device through pipes.

[0068] The first upper side panel 12, the second upper side panel 13, the third upper side panel 14, the fourth upper side panel 15, the fifth upper side panel 18, and the sixth upper side panel 19 are vertically connected to the top panel 11, and together form a rectangular shell structure with an opening facing upward. The first lower side panel 22, the second lower side panel 23, the third lower side panel 25, and the fourth lower side panel 26 are vertically connected to the bottom panel 21, and together form a rectangular shell structure with an opening facing upward. The fifth upper side panel 18 and the third lower side panel 25, and the sixth upper side panel 19 and the fourth lower side panel 26 are respectively connected by the corresponding first snap-fit ​​portion 16 and the first snap-fit ​​portion 24. The first snap-fit ​​member 1 and the second snap-fit ​​member 2 are connected to form a accommodating space with limited left and right, up and down, and front and back. The radiator is placed inside it to prevent shaking.

[0069] like Figure 1 and Figure 2 As shown, guide plates 10 are provided on each of the first, second, third, and fourth upper side panels 12, 13, 14, and 15. These guide plates 10 extend away from the top panel 11 and are tilted toward the outside of the corresponding side panel. Specifically, the guide plates 10 on the first upper side panel 12 are tilted toward the outside of the first upper side panel 12, the guide plates 10 on the second upper side panel 13 are tilted toward the outside of the second upper side panel 13, the guide plates 10 on the third upper side panel 14 are tilted toward the outside of the third upper side panel 14, and the guide plates 10 on the fourth upper side panel 15 are tilted toward the outside of the fourth upper side panel 15. The guide plates 10 facilitate the secure installation of the first fastener 1 on the second fastener 2 and the shielding cage 3. Precise alignment of the first and second fasteners 1 and 2 is not required; the guide plates 10 provide quick guidance and facilitate installation. The guide plates 10 also facilitate quick installation of the heat sink fastening structure and the shielding cage 3. The guide plate 10 can reduce the difficulty of installing the radiator's snap-fit ​​structure and improve the installation efficiency.

[0070] The top surface of the first fastening member 1 is provided with a plurality of elastic pressing pieces 112 extending inwardly of the top surface. After the first fastening member 1 and the second fastening member 2 are connected, the elastic pressing pieces 112 are used to press the upper surface of the heat sink 4 to prevent the heat sink 4 from moving in the accommodation space.

[0071] In this embodiment, if Figure 1 and Figure 2As shown, the top plate 11 of the first fastener 1 is provided with a first heat dissipation hole 111. The first heat dissipation hole 111 is used to increase the heat exchange efficiency between the radiator 4 located in the accommodating space and the outside air, thereby improving the cooling efficiency of the radiator 4. The first heat dissipation hole 111 is preferably, but not limited to, a rectangular hole. The first heat dissipation hole 111 can also be selected to be circular, triangular or polygonal. In this embodiment, there are multiple first heat dissipation holes 111, and the multiple first heat dissipation holes 111 are spaced apart along the length and width directions of the top plate 11, that is, arranged in a matrix form. In addition, the first heat dissipation holes 111 can also be used as lightweight holes to reduce the weight of the first fastener 1.

[0072] Furthermore, an elastic pressing piece 112 is provided on one side of the first heat dissipation hole 111. The elastic pressing piece 112 extends into the accommodation space and is used to press the upper surface of the heat sink 4 to prevent the heat sink 4 from moving within the accommodation space. The elastic pressing piece 112 can adjust the tightness between the heat sink 4 and the heating device (such as the optical module 5) by pressing the heat sink 4, thereby ensuring that the heat sink 4 and the heating device (such as the optical module 5) are tightly fitted.

[0073] In this embodiment, multiple first heat dissipation holes 111 are arranged in a matrix on the top plate 11, which enables multiple elastic pressing plates 112 to be arranged in a matrix as well. The multiple elastic pressing plates 112 arranged in a matrix can apply balanced pressure to different locations on the upper surface of the heat sink 4, allowing the heat sink 4 to fit tightly against all optical modules 5, thereby ensuring good uniformity in heat dissipation from each optical module 5, improving the cooling effect of the entire optical module system, and preventing the accuracy of the optical module system from being affected by local overheating (individual optical modules). Because the heat sink is fixed within the heat sink snap-fit ​​structure, when an optical module 5 is pulled out, the floating and heat dissipation effects on the remaining optical modules 5 are minimal.

[0074] Preferably, the elastic pressing piece 112 is integrally formed with the top plate 11. That is, when the first heat dissipation hole 111 is cut or punched into the top plate 11, the cut or punched portion of material is not completely separated from the top plate 11. This portion of material forms the elastic pressing piece 112 extending toward one side of the receiving space. Integrally forming the elastic pressing piece 112 with the top plate 11 reduces assembly steps, eliminating the need for additional welding or fasteners, while also improving strength and stability and reducing costs.

[0075] like Figure 1 As shown, the bottom plate 21 is provided with a second heat dissipation hole 211. Figure 5As shown, the second heat dissipation hole 211 is used to allow the radiator 4 to at least partially extend, so that the extended portion of the radiator 4 can be limitedly connected to the shielding cage 3. In addition, the second heat dissipation hole 211 can also be used to increase the heat exchange efficiency between the radiator 4 located in the accommodating space and the outside air, thereby improving the cooling efficiency of the radiator 4. The second heat dissipation hole 211 is preferably, but not limited to, a rectangular hole. The second heat dissipation hole 211 can also be selected to be circular, triangular or polygonal. In this embodiment, there are multiple second heat dissipation holes 211, and the multiple second heat dissipation holes 211 are spaced apart along the length direction of the bottom plate 21. The number of second heat dissipation holes 211 is set according to the number of the extended portions of the radiator 4 (i.e., the bosses 43), and the positions and shapes are basically the same, so as to facilitate extension and connection.

[0076] like Figure 1 As shown, the bottom plate 21 is also provided with a clearance hole 212. Multiple clearance holes 212 are provided, and the plurality of clearance holes 212 are spaced apart along the width direction of the bottom plate 21. The clearance holes 212 are used to avoid the protruding structure on the shielding cage 3 when the heat sink snap-fit ​​structure is connected to the shielding cage 3, thereby improving the stability of the connection.

[0077] The heat sink fastening structure of this embodiment is composed of a first fastening part and a second fastening part fastened together to wrap the heat sink as a whole, preventing the heat sink from displacement or loosening when subjected to external impact or vibration, thereby ensuring its stability and reliability.

[0078] Figure 10 and Figure 11 Schematic diagram of the structure of the optical module and the shielding cage assembly. The shielding cage assembly includes a heat sink buckling structure, a shielding cage 3 and a heat sink 4. The heat sink buckling structure is consistent with the heat sink buckling structure in the above embodiment and will not be repeated. Figure 4 、 Figure 5 As shown, the radiator 4 is installed in the accommodation space of the radiator snap-fit ​​structure, which can prevent the radiator 4 from shaking up and down or left and right. The radiator 4 and the radiator snap-fit ​​structure can be assembled and connected to the shielding cage 3 as a whole, facilitating the rapid adjustment of the radiator 4 according to different heat dissipation requirements and improving assembly and disassembly efficiency.

[0079] The radiator 4 is preferably, but not limited to, a liquid cooling radiator. The liquid cooling radiator cools down the optical module 5 in the shielding cage 3 by passing cooling liquid into the radiator 4 , which has a better cooling effect.

[0080] like Figure 6-Figure 8As shown, the radiator 4 includes a liquid cooling plate 41 and a pressing plate 42. The pressing plate 42 is mounted on the top surface of the liquid cooling plate 41 to ensure that multiple elastic pressing plates 112 can abut on the same plane and maintain the same degree of tightness. The pressing plate 42 is used to abut the elastic pressing plates 112 of the radiator's snap-fit ​​structure to ensure that the radiator 4 and the optical module 5 are tightly fitted or kept at a relatively close distance from each other, preventing the radiator 4 from moving up and down. At the same time, the multiple elastic pressing plates 112 are pressed against the radiator 4 by abutting against the pressing plate 42, ensuring that the radiator 4 and the multiple optical modules 5 have the same degree of tightness or distance, so that the heat dissipation of the multiple optical modules 5 is uniform and the adverse effects caused by local overheating are avoided. The liquid cooling plate 41 is provided with an internal flow channel, which is provided with a liquid outlet and a liquid inlet. The liquid outlet and the liquid inlet are respectively connected to the liquid storage device through pipes. The heat of the optical module 5 is removed by the flow of coolant in the internal flow channel, achieving heat dissipation and cooling.

[0081] like Figure 7 As shown, the heat sink 4 also includes bosses 43, which are protruding from the bottom surface of the liquid cooling plate 41. The number, position, and shape of the bosses 43 are consistent with the number, position, and shape of the second heat dissipation holes 211. When the heat sink 4 is installed in the heat sink snap-fit ​​structure, the bosses 43 extend from the corresponding second heat dissipation holes 211.

[0082] In this embodiment, the second heat dissipation hole 211 is a rectangular through-hole, correspondingly, the boss 43 is a cuboid. Furthermore, the second heat dissipation hole 211 and the boss 43 are substantially the same size, and the second heat dissipation hole 211 is aligned with the boss 43. As a result, after the boss 43 extends from the second heat dissipation hole 211, due to its equal size, it will not wobble, and the structure is more stable. In some alternative embodiments, the second heat dissipation hole 211 can also be a circular, polygonal, or irregularly shaped through-hole, and the boss 43 can also be a three-dimensional shape of another type, which is not limited in this embodiment.

[0083] like Figure 9 As shown, the shielding cage 3 is provided with a second snap-fitting portion 31 on each side thereof, which snaps into contact with the second snap-fitting portion 17 of the heat sink snap-fitting structure. The number of second snap-fitting portions 31 on each side of the shielding cage 3 matches the number of second snap-fitting portions 17 on the third upper side plate 14 and the fourth upper side plate 15, and their positions correspond to each other, facilitating secure installation and removal, and improving connection stability. In this embodiment, the second snap-fitting portions 17 are snap-fitting holes, and the second snap-fitting portions 31 are hooks that extend upward from both sides of the top surface of the shielding cage 3 and then bend toward the exterior of the shielding cage 3. Alternatively, the second snap-fitting portions 31 can be protruding bumps that protrude toward the exterior of the shielding cage 3. The snap-fitting holes can be triangular, rectangular, polygonal, or circular, and the bumps can be triangular, rectangular, polygonal, or circular.

[0084] like Figure 9 As shown, the shielding cage 3 includes a receiving cavity 32, and the receiving cavity 32 is used to install the optical module 5. Figure 9 As shown, a third heat dissipation hole 33 is formed on the top surface of the shielding cage 3 and communicates with the accommodating cavity 32. The third heat dissipation hole 33 allows the boss 43 of the heat sink 4 to pass through and extend into the accommodating cavity 32, thereby directly contacting or bringing it closer to the optical module 5, thereby improving heat dissipation efficiency to a certain extent.

[0085] In this embodiment, multiple accommodating cavities 32 are arranged side by side along the length of the shielding cage 3. Each accommodating cavity 32 can accommodate an optical module 5, which improves information exchange efficiency. Accordingly, multiple third heat dissipation holes 33 are provided, each corresponding one-to-one with the multiple accommodating cavities 32. Furthermore, multiple second heat dissipation holes 211 and bosses 43 are provided, each corresponding one-to-one with the multiple third heat dissipation holes 33. The bosses 43 extend into corresponding third heat dissipation holes 33 and then into corresponding accommodating cavities 32, allowing them to directly contact or come into close proximity with the optical modules 5, ensuring uniform and efficient heat dissipation across the multiple optical modules 5.

[0086] In this embodiment, the accommodating cavity 32 is a rectangular hollow structure, and the third and second heat dissipation holes 33 and 211 are rectangular through-holes. Correspondingly, the boss 43 is a cuboid. Furthermore, the third and second heat dissipation holes 33 and 211 are substantially the same size as the boss 43, and the third and second heat dissipation holes 33 and 211 are aligned with the boss 43. As a result, after the boss 43 extends from the second and third heat dissipation holes 211 and 33, due to their similar sizes, it will not shake, and the structure will be more stable. In some alternative embodiments, the third and second heat dissipation holes 33 and 211 can also be configured as circular, polygonal, or irregularly shaped through-holes, and the boss 43 can also be configured as other three-dimensional shapes, which are not limited in this embodiment.

[0087] This embodiment also provides an optical module device, which includes a shielding cage assembly and optical modules 5. The structure of the shielding cage assembly is consistent with that described above and will not be repeated here. The optical modules 5 are disposed within the accommodating cavity 32 of the shielding cage 3, and the number of optical modules 5 matches the number of accommodating cavities 32.

[0088] In the embodiment of the present application, the radiator snap-fit ​​structure is configured to be a structure that can be entirely wrapped around the outside of the radiator. After being connected to the shielding cage, it can ensure good contact between the radiator and the heat source (optical module), thereby improving heat dissipation efficiency. The overall structure formed by the snap-fit ​​connection can provide better mechanical support, prevent the radiator from being displaced or loosened when subjected to external impact or vibration, and ensure its stability and reliability. The overall wrapping design can be quickly adjusted according to different heat dissipation requirements and is suitable for a variety of different devices and applications. The snap-fit ​​design of the radiator snap-fit ​​structure itself and the snap-fit ​​connection between it and the shielding cage can be installed or removed without tools, which simplifies the installation process, saves time and cost, and also facilitates subsequent maintenance or replacement.

[0089] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
