[0034] Reference Figures 1-12 Some embodiments of this utility model relate to a heat dissipation assembly, which includes a substrate 1, a heat sink mounting bracket 2, a heat sink 3, and a connecting bracket 5. The connecting bracket 5 is fixed relative to the substrate 1, and the heat sink mounting bracket 2 is mounted on the substrate 1 via the connecting bracket 5. The heat sink mounting bracket 2 and the substrate 1 are arranged at intervals along a first direction X1. The heat sink mounting bracket 2 has a receiving shell 21, which has a space for receiving the heat sink 3, and the heat sink 3 is installed in the space for receiving the heat sink 3. In this embodiment, the first direction X1 can be the normal direction of the contact surface between the heat sink 3 and the component to be cooled. For example, in this embodiment, the first direction X1 can be the thickness direction of the heat sink 3. The heat sink 3 has a flow channel 31 for the flow of coolant. The heat absorbed by the heat sink 3 from the component to be cooled is transferred to the coolant, and the coolant flows in the flow channel 31 to carry away the heat. The component to be cooled can be any device that can be cooled by the heat sink 3, for example, a reference device. Figure 9 and Figure 10 In some embodiments, the heat-dissipating component may be an optical module 10.

[0035] In this embodiment of the invention, the heat dissipation assembly is provided with at least two heat dissipation plate mounting brackets 2, which are arranged at intervals along a first direction X1, such that multiple heat dissipation plate mounting brackets 2 occupy different positions relative to the substrate 1 in the first direction X1. Multiple heat dissipation plates 3 are distributed among multiple heat dissipation plate mounting brackets 2. A space for placing a component to be cooled is formed between a heat dissipation plate mounting bracket 2 and another adjacent heat dissipation plate mounting bracket 2 along the first direction X1, or between the substrate 1 and a heat dissipation plate mounting bracket 2 near the substrate 1. Thus, the heat dissipation assembly forms a three-dimensional heat dissipation structure that can accommodate multiple layers of components to be cooled.

[0036] Multiple heat sinks 3 can be connected in series, thereby driving the coolant within the multiple heat sinks 3 using a set of coolant driving devices (e.g., pumps). In some embodiments, the heat dissipation assembly also includes multiple guide pipes 4, which are connected to the ends of the heat sinks 3 and communicate with the flow channels 31. The guide pipes 4 serve as channels 71 for the coolant to enter and exit the heat sinks 3.

[0037] In some embodiments, the heat sink mounting bracket 2 has a first connecting ear 22 connected to the receiving shell 21, the connecting bracket 5 has a mounting arm 51, and the heat dissipation assembly further has a first connector 6, which connects the first connecting ear 22 and the mounting arm 51 to mount the heat sink mounting bracket 2 to the connecting bracket 5. In this embodiment, referring to... Figure 5 and Figure 6 The first connecting ear 22 has a first wedge-shaped surface 221, which is inclined to the first direction X1. The mounting arm 51 has a second wedge-shaped surface 52, which is disposed opposite to the first wedge-shaped surface 221. The first wedge-shaped surface 221 can be positioned so that the first connecting ear 22 faces away from the substrate 1. When the first connecting member 6 connects the first connecting ear 22 and the mounting arm 51, the first wedge-shaped surface 221 and the second wedge-shaped surface 52 can be pressed against each other, pulling the heat sink mounting bracket 2 so that the receiving shell 21 is closer to the substrate 1, thereby allowing the heat sink 3 to better contact the heat sink component placed near the heat sink mounting bracket 2 on the side close to the substrate 1. The first connecting member 6 can be a screw, bolt, or other fastener.

[0038] In some embodiments, the first connecting ear 22 includes a limiting portion 222 and a connecting portion 223. A first wedge-shaped surface 221 is disposed on the limiting portion 222, and the connecting portion 223 has a first connecting hole 2231. The mounting arm 51 has a second connecting hole 53. A predetermined angle is formed between the limiting portion 222 and the connecting portion 223, for example, the angle between the limiting portion 222 and the connecting portion 223 can be 90°, and the extending direction of the second connecting hole 53 is not parallel to either the first direction X1 or the second wedge-shaped surface 52. The first connecting member 6 connects the first connecting hole 2231 and the second connecting hole 53 so that the first wedge-shaped surface 221 and the second wedge-shaped surface 52 are pressed against each other. When the first connector 6 passes through the first connecting hole 2231 and is screwed into the second connecting hole 53, by adjusting the length of the first connector 6 being screwed in, the first wedge surface 221 can be pushed closer to or further away from the second wedge surface 52. Since the first wedge surface 221 and the second wedge surface 52 are inclined to the first direction X1, when the first wedge surface 221 and the second wedge surface 52 are pressed against each other under the action of the first connector 6, an interaction force along the first direction X1 will be generated at the same time, thereby driving the receiving shell 21 to move closer to or further away from the substrate 1 through the first connecting ear 22.

[0039] In some embodiments, refer to Figure 4 and Figure 9 The heat sink mounting bracket 2 has two first connecting ears 22, which are respectively located at both ends of the heat sink mounting bracket 2 along its length, and are used to fix the heat sink mounting bracket 2 from both ends. The mounting arm 51 has a main body 511 and a protrusion 512. The main body 511 has a limiting surface 513, which faces the mounting arm 51 at the other end of the heat sink mounting bracket 2. The protrusion 512 protrudes from the limiting surface 513, and a second wedge-shaped surface 52 is provided on the protrusion 512. The outer side of the limiting part 222 is opposite to the limiting surface 513, wherein the outer side of the limiting part 222 is the side of each limiting part 222 away from the other connecting ear of the heat sink mounting bracket 2. Thus, the outer sides of the limiting parts 222 of the first connecting ears 22 at both ends of the heat sink mounting bracket 2 are sandwiched between two connecting brackets 5, and the connection position of the first wedge-shaped surface 221 and the second wedge-shaped surface 52 can be protected by the connecting brackets 5.

[0040] In some embodiments, refer to Figures 1-4The heat sink mounting bracket 2 also has a second connecting ear 23, which is spaced apart from the first connecting ear 22 and connected to the connecting bracket 5. The second connecting ear 23 has a third connecting hole 231, and the connecting bracket 5 also has a fourth connecting hole 54 extending along a first direction X1. The heat sink assembly also includes a second connector 8, which passes through the third connecting hole 231 and the fourth connecting hole 54 to connect the second connecting ear 23 to the connecting bracket 5. Optionally, the second connector 8 can be a screw, bolt, or other fastener. Thus, the first connector 6 and the second connector 8 fix the heat sink mounting bracket 2 to the connecting bracket 5 from two different directions, enhancing the stability of the heat sink mounting bracket 2 installation.

[0041] The substrate 1 has multiple fifth connection holes 11. In some embodiments, the heat dissipation assembly further includes a third connector 80, and the connecting bracket 5 also has a sixth connection hole 57. The third connector 80 passes through the fifth connection holes 11 and the sixth connection hole 57 to fix the connecting bracket 5 to the substrate 1, thereby enhancing the installation stability of the connecting bracket 5. Optionally, the third connector 80 can be a screw, bolt, or other fastener. In some embodiments, the second connector 8 can be made longer, and the fourth connection hole 54 can be aligned with the fifth connection hole 11, so that at least one second connector 8 passes through the fourth connection hole 54 and also through the corresponding fifth connection hole 11 to connect the second connecting lug 23, the connecting bracket 5, and the substrate 1, thereby enhancing the stability of the overall structure.

[0042] In some embodiments, at least two heat sink mounting brackets 2 can be connected to the same connecting bracket 5, thereby facilitating the maintenance of the relative positions between multiple heat sink mounting brackets 2. For example, refer to Figures 1-4 At least one connecting bracket 5 has multiple mounting arms 51, which are spaced apart from each other. The connecting bracket 5 also has a connecting arm 55, which connects the multiple mounting arms 51. Each mounting arm 51 can be connected to a heat sink mounting bracket 2 located at a different position, thereby connecting multiple heat sink mounting brackets 2 into a whole.

[0043] In other embodiments, the connecting bracket 5 may also be connected to a heat sink mounting bracket 2, and the first connecting ear 22 and the second connecting ear 23 may be connected to different connecting brackets 5 respectively. For example, see reference Figure 7 and Figure 8 The first connecting ear 22 and the second connecting ear 23 of the heat sink mounting bracket 2 near the substrate 1 are respectively mounted on two different connecting brackets 5.

[0044] The substrate 1 has a first side 12 and a second side 13 opposite to each other along a first direction X1, and multiple heat sink mounting brackets 2 can be disposed on the same side of the substrate 1 (e.g., Figures 1-4(as shown), or heat sink mounting brackets 2 can be provided on both sides of the substrate 1. In some embodiments, at least one heat sink mounting bracket 2 and at least one connecting bracket 5 are respectively provided on the first side 12 and the second side 13, for example, referring to Figure 7 and Figure 8 Each of the first side 12 and the second side 13 of the substrate 1 has two heat sink mounting brackets 2. Optionally, connecting the connecting brackets 5 on both sides of the substrate 1 to the substrate 1 using the same component helps reduce assembly difficulty and ensures the overall stability of the heat dissipation assembly. In one embodiment, referring to... Figure 8 A second connector 8 can be used to pass through the connecting bracket 5 on the first side 12 of the substrate 1, the fifth connecting hole 11, and the connecting bracket 5 on the second side 13 of the substrate 1, so as to achieve the effect of connecting the heat sink mounting brackets 2, the connecting brackets 5 and the substrate 1 on both sides of the two substrates with a second connector 8, and to achieve the positioning between multiple heat sink mounting brackets 2.

[0045] In some embodiments, continue to refer to Figure 8 A third connector 80 can be used, passing through the sixth connecting hole 57 and the fifth connecting hole 11 of the connecting bracket 5 on the first side 12 of the substrate 1 and the sixth connecting hole 57 of the connecting bracket 5 on the second side 13 of the substrate 1. In one embodiment, the substrate 1 also has a positioning hole 14, with a certain gap between the positioning hole 14 and the fifth connecting hole 11. The bottom of the connecting bracket 5 also has a protruding positioning block 56, which is inserted into the positioning hole 14. At the same time, the sixth connecting hole 57 is aligned with the fifth connecting hole 11, and the third connector 80 connects the two connecting brackets 5 and the substrate 1.

[0046] Reference Figure 1 , Figure 9 and Figure 10 The housing 21 has a first end plate 213 and a second end plate 214, with the second end plate 214 and the first end plate 213 disposed opposite each other along a first direction X1 in the space accommodating the heat sink 3. The first end plate 213 has a spring tab 215 extending into the space accommodating the heat sink 3, which presses the heat sink 3 against the second end plate 214. When the heat dissipation assembly is in use, the component to be cooled (e.g., Figure 9 and Figure 10The optical module 10 in the middle is opposite to the second end plate 214. The heat sink 3 is pressed onto the second end plate 214 by the spring piece 215, so that the heat sink 3 and the heat dissipation component can make full contact for heat exchange. In this embodiment, the second end plate 214 can be the side of the housing 21 near the substrate 1. In one embodiment, the housing 21 includes a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 are arranged opposite to each other and connected along the first direction X1. A space for accommodating the heat sink 3 is formed between the first housing 211 and the second housing 212. The first end plate 213 is disposed in the first housing 211 and the second end plate 214 is disposed in the second housing 212. The first housing 211 and the second housing 212 can be connected by a snap-fit. After the heat sink 3 is installed between the first housing 211 and the second housing 212, the first housing 211 and the second housing 212 are snap-fit ​​connected. The spring piece 215 presses the heat sink 3 against the second end plate 214, and at the same time provides a certain locking force for the snap-fit ​​connection between the first housing 211 and the second housing 212.

[0047] The second end plate 214 has a first heat exchange hole 216, and the heat sink 3 has a heat exchange part 32. The heat exchange part 32 protrudes from the first heat exchange hole 216 from the second end plate 214 so as to make contact with the component to be scald to achieve heat exchange, and can also serve to position the heat sink 3 and the heat sink mounting bracket 2.

[0048] The heat dissipation assembly also includes a mounting cage 9, which is located on the side of the second end plate 214 near the substrate 1 and fixed relative to the substrate 1. The mounting cage 9 has a space for receiving the heat-dissipating component, in which the heat-dissipating component can be placed and its heat transferred to the heat dissipation plate 3 in the heat dissipation plate mounting bracket 2. Optionally, the side wall of the mounting cage 9 opposite to the second end plate 214 has a second heat exchange hole 91 opposite to the first heat exchange hole 216. The second heat exchange hole 91 communicates with the space for receiving the heat-dissipating component, wherein the heat exchange part 32 also passes through the second heat exchange hole 91 into the space for receiving the heat-dissipating component, so as to facilitate contact with the heat-dissipating component placed in the space for receiving the heat-dissipating component to achieve heat exchange. The first wedge-shaped surface 221 of the first connecting member 6, the first wedge-shaped surface 221 of the first connecting ear 22, and the second wedge-shaped surface 52 of the mounting arm 51 cooperate to provide a pulling force to the receiving shell 21 in the direction close to the substrate 1, while the spring piece 215 provides a pressing force to the heat dissipation plate 3 in the direction close to the substrate 1, so that the heat dissipation plate 3 can fully contact and exchange heat with the heat-dissipating component placed on the side of the second end plate 214.

[0049] The pipe connector 7 is used to connect two heat sinks 3 arranged at different positions along the first direction X1, thereby connecting the multi-layer heat sinks 3 in series. (Refer to...) Figures 1-3 as well as Figure 11 and Figure 12The pipe connector 7 has a channel 71 and at least two interfaces 72 communicating with the channel 71, each interface 72 being connected to a guide pipe 4 of a corresponding heat sink 3. The pipe connector 7 is configured to be retractable in the first direction X1, thereby accommodating positional fluctuations and installation position errors of the two heat sinks 3 located at different positions in the first direction X1.

[0050] In some embodiments, the pipe connector 7 includes a floating section 73, a first connecting end 74, and a second connecting end 75. The floating section 73 is telescopic in a first direction X1, the first connecting end 74 is located at one end of the floating section 73, and the second connecting end 75 is located at the other end of the floating section 73. When the floating section 73 floats and expands along the first direction X1, the distance between the first connecting end 74 and the second connecting end 75 also changes. The first connecting end 74 and the second connecting end 75 each have an interface 72. The interface 72 of the first connecting end 74 and the interface 72 of the second connecting end 75 are respectively connected to a corresponding guide pipe 4.

[0051] In some embodiments, the pipe fitting 7 includes a first fitting 76 and a second fitting 77 detachably connected to each other. The first fitting 76 has a first connecting end 74 and a first floating end 761, and the second fitting 77 has a second connecting end 75 and a second floating end 771, wherein the first floating end 761 and the second floating end 771 are arranged along a first direction X1 and are floatingly connected to form at least a portion of the floating section 73. The connection between the second floating end 771 and the first floating end 761 is sealed with a seal to prevent coolant leakage. The seal can adopt a suitable movable sealing method as needed to ensure a good sealing effect while ensuring that the first floating end 761 and the second floating end 771 can move relative to each other along the first direction X1, for example, a bellows seal, a packing seal, or other sealing methods can be used. In one embodiment, the first floating end 761 has a socket 762, and the outer contour of the second floating end 771 is slightly smaller than the socket 762 and is inserted into the socket 762 along the first direction X1. The outer wall of the second floating end 771 has a first sealing groove 772, and the sealing element includes a first sealing ring 78. The first sealing ring 78 is disposed in the first sealing groove 772 and is pressed against the inner wall of the socket 762 to achieve a seal. To achieve a good sealing effect, multiple parallel first sealing grooves 772 can be provided on the second floating end 771 at intervals along the first direction X1, and a corresponding first sealing ring 78 can be provided in each first sealing groove 772.

[0052] The guide tube 4 has a third connecting end 41, which is inserted into the interface 72 to connect the guide tube 4 to the connector 7. In one embodiment, the guide tube 4 can be arranged in a direction substantially perpendicular to the first direction X1, with the first connecting end 74 intersecting the floating section 73, and the second connecting end 75 intersecting the floating section 73. The normal direction of the interface 72 is perpendicular to the first direction X1 to facilitate the connection between the guide tube 4 and the interface 72. During installation, the first connector 76 and the second connector 77 can be connected first, then the first connecting end 74 can be connected to the third connecting end 41 of one of the guide tubes 4, and the second connecting end 75 can be connected to the third connecting end 41 of the other guide tube 4 to be connected. During installation, the extensibility of the floating section 73 can adapt to the position between the two guide tubes 4 to be connected.

[0053] The pipe fitting 7 also includes a limiting member, which connects the first connecting end 74 and the second connecting end 75 to limit the relative position of the first connecting end 74 and the second connecting end 75, preventing the first connecting end 74 and the second connecting end 75 from twisting or shifting due to the extension and retraction of the floating section 73.

[0054] In one embodiment, refer to Figure 3 , Figure 11 and Figure 12 The outer surface of the first connecting end 74 has two opposing limiting grooves 741, and the outer surface of the second connecting end 75 has two spaced-apart limiting holes 751. The limiting grooves 741 and limiting holes 751 extend along a direction intersecting the insertion direction of the interface 72 and the guide tube 4. For example, the limiting grooves 741 and limiting holes 751 can be substantially perpendicular to the insertion direction of the interface 72 and the guide tube 4. The limiting member includes a retaining ring 79, which includes a meandering portion 791 and two free arms 792. The two free arms 792 are located at both ends of the meandering portion 791 and are spaced apart. The retaining ring 79 has a certain elasticity, allowing the relative position between the two free arms 792 to change within a certain range. The detour portion 791 spans the side of the first connecting end 74 away from the second connecting end 75. Each free arm 792 passes through a corresponding limiting groove 741 and the end away from the detour portion 791 is inserted into a corresponding limiting hole 751. Thus, the first connecting end 74 and the second connecting end 75 can be connected by the snap ring 79.

[0055] Optionally, the free arm 792 may have a bent portion 793, with each bent portion 793 bending towards the opposite free arm 792. The distance between the bent portions 793 of the two free arms 792 is less than the distance between the two limiting grooves 741. When the retaining ring 79 is installed to the first connecting end 74, due to the elasticity of the retaining ring 79, the bent portion 793 can move along the surface of the first connecting end 74 until the bent portion 793 disengages from the surface of the first connecting end 74. When the retaining ring 79 is connected to the first connecting end 74, the bottom of the meandering portion 791 spans the side of the first connecting end 74 away from the second connecting end 75, while the bent portion 793 is located on the side of the first connecting end 74 closer to the second connecting end 75. The meandering portion 791 and the two bent portions 793 cooperate to restrict the movement of the retaining ring 79 along the first direction X1, preventing the retaining ring 79 from disengaging from the pipe joint 7 along the first direction X1.

[0056] In some embodiments, the outer surface of the third connecting end 41 has a second sealing groove 42 and an annular groove 43, which are spaced apart from each other along the length of the third connecting end 41. The guide tube 4 also includes a second sealing ring 44, which is disposed in the second sealing groove 42. When the third connecting end 41 is inserted into the interface 72, the second sealing ring 44 is pressed between the second sealing groove 42 and the inner wall of the channel 71 to achieve a seal. The annular groove 43 is disposed on the side of the second sealing groove 42 away from the end of the third connecting end 41 to ensure the sealing between the connector and the guide tube 4. The end of the third connecting end 41 refers to the end away from the connection end between the guide tube 4 and the heat sink 3. After the third connecting end 41 is inserted into the interface 72, the annular groove 43 is aligned with the corresponding positioning groove or positioning hole 751, and the free arm 792 is also disposed in the annular groove 43 to prevent the pipe connector 7 from coming out of the guide tube 4. Therefore, the limiting component can not only limit the position of the first connecting end 74 and the second connecting end 75, but also position the third connecting end 41 to the interface 72 and prevent it from coming off.

[0057] The heat dissipation assembly of this utility model embodiment includes a substrate 1, a heat dissipation plate mounting bracket 2, a heat dissipation plate 3, a guide pipe 4, a connecting bracket 5, a first connector 6, and a pipe joint 7. The guide pipe 4 is connected to the heat dissipation plate 3. There are at least two heat dissipation plate mounting brackets 2, which are arranged along the first direction X1 and spaced apart from each other. A first wedge-shaped surface 221 is provided on the first connecting ear 22 of the heat dissipation plate mounting bracket 2. The first wedge-shaped surface 221 is inclined to the first direction X1. A second wedge-shaped surface 52 is provided on the mounting arm 51. The first connector 6 connects the first connecting ear 22 and the mounting arm 51 and makes the first wedge-shaped surface 221 and the second wedge-shaped surface 52 press against each other so that the receiving shell 21 is close to the base. This allows the heat dissipation plate 3 to be tightly attached to the heat dissipation component on the side of the heat dissipation plate 3 close to the base, ensuring efficient and stable heat dissipation. In addition, the two guide pipes 4 are connected by the retractable pipe joint 7 in the first direction X1, which is beneficial to adapt to the floating position of the heat dissipation plate mounting bracket 2 in the first direction X1, ensuring the stability and reliability of the overall structure.

[0058] Another embodiment of this utility model relates to an optical module device, see reference 1 Figure 9 The optical module device includes an optical module 10 and a heat dissipation component, wherein the heat dissipation component is the heat dissipation component described in at least some of the embodiments above, such as... Figure 10 As shown, the optical module 10 is housed in the heat dissipation space of the mounting cage 9 and is in contact with the heat sink 3. The heat generated by the optical module 10 can be transferred to the heat sink 3 and carried away by the flow of coolant. The stacked design of the heat dissipation components can effectively improve the space utilization of the optical module device while ensuring heat dissipation performance.
