Description

Technical Field

[0001] This utility model relates to a sandwich-type optical module water-cooling heat dissipation device, and more particularly to an optical module heat dissipation device installed in electronic equipment to assist heat dissipation by water cooling. Background Technology

[0002] The connector of a small pluggable transceiver can be housed inside a metal cage. Optical modules can be inserted into this cage, allowing them to interlock with the connector for connection. Existing technology may include a heat sink on top of the metal cage, which helps dissipate heat when the optical module is inserted. However, in existing multi-port metal cages (e.g., 1xN or 2xN), the water-cooling plate is integrated (multiple ports share the same plate, and each port lacks independent vertical floating functionality). When multiple optical modules are inserted into the cage, their varying heights mean that taller modules may not reach the heat sink, causing a sudden increase in thermal resistance and leading to abnormal heat dissipation. Furthermore, the lack of floating functionality in the water-cooling plate makes insertion difficult and can easily wear down the heat dissipation contact surface, potentially causing similar heat dissipation issues over time. Utility Model Content

[0027] [Example]

[0028] Please see Figures 1 to 4 This utility model provides a sandwich-type optical module water-cooling heat dissipation device, including a water inlet 2, a water outlet 3, a main water-cooling plate 4, multiple floating sub-water-cooling plates 5, and two metal shells 6. This embodiment discloses a 2×4 structure, which can accommodate eight optical modules, but the specifications are not limited; for example, 2×2 to 2×6 specifications are all possible, allowing for the insertion of multiple optical modules. This embodiment discloses that the water-cooling heat dissipation device is sandwiched between the two metal shells 6. It can also be stacked like building blocks, with multiple layers depending on the end-user's usage scenario, ensuring that a layer of the water-cooling heat dissipation device is sandwiched between every two metal shells 6.

[0029] The inlet head 2 is used to input coolant. The outlet head 3 is used to output the coolant after heat exchange.

[0030] The main water-cooled plate 4 is provided with a water inlet space 41 and a water outlet space 42 (e.g., ...). Figure 7 As shown, the water inlet space 41 and the water outlet space 42 are connected to the water inlet head 2 and the water outlet head 3 respectively, so that the coolant input by the water inlet head 2 can be delivered to the water inlet space 41 of the main water cooling plate 4, and the coolant after heat exchange can be delivered to the water outlet head 3 through the water outlet space 42 of the main water cooling plate 4.

[0031] The main water-cooled plate 4 may include a main water-cooled plate body 43 and a main water-cooled plate cover 44. The water inlet space 41 and the water outlet space 42 are located between the main water-cooled plate body 43 and the main water-cooled plate cover 44. The main water-cooled plate cover 44 covers one side of the main water-cooled plate body 43 and is used to seal the water inlet space 41 and the water outlet space 42. The main water-cooled plate cover 44 can be fixed to the main water-cooled plate body 43 by welding or other means, so that the coolant can flow in the water inlet space 41 and the water outlet space 42 without leakage.

[0032] Please see Figures 4 to 6 Multiple floating sub-water-cooled plates 5 are respectively disposed above and below the main water-cooled plate 4. The multiple floating sub-water-cooled plates 5 above and below the main water-cooled plate 4 are arranged in a row, forming an upper floating sub-water-cooled plate 5 and a lower floating sub-water-cooled plate 5, thus forming an optimized configuration. The multiple floating sub-water-cooled plates 5 sandwich the main water-cooled plate 4 in the middle, thereby forming a sandwich design, which can be used to form a sandwich optical module water-cooling heat dissipation device. Each of the multiple floating sub-water-cooled plates 5 is provided with a flow channel 51 (e.g., Figures 8 to 10 As shown in the figure, in this embodiment, the floating sub-water-cooled plate 5 may include a floating sub-water-cooled plate body 52 and a floating sub-water-cooled plate cover 53.

However, the combination method of the floating sub-water-cooled plate cover 53 and the floating sub-water-cooled plate body 52 is not limited. The floating sub-water-cooled plate cover 53 can be fixed to the floating sub-water-cooled plate body 52 by means of welding or other methods, so that the coolant can flow in the flow channel 51 without leakage.

In this embodiment, each of the multiple elastic elements 8 is fitted with a fastener 20 (e.g., ...). Figure 11 As shown, the fastener 20 is inserted into the elastic member 8. The fastener 20 can be fixed to the main water-cooling plate 4, and the fastener 20 can fasten the floating sub-water-cooling plate 5, so that the elastic member 8 and the floating sub-water-cooling plate 5 can be stably positioned.

[0034] Two metal housings 6 are respectively disposed on opposite sides of the plurality of floating sub-water-cooled plates 5, such that the plurality of floating sub-water-cooled plates 5 are sandwiched between the two metal housings 6. The two metal housings 6 can also be respectively disposed on a circuit board 9 (e.g., Figure 1 and Figure 2 (As shown). Each of the two metal housings 6 has multiple accommodating spaces 61 for inserting the optical module 100 (e.g., Figure 4 As shown, the optical module 100 can be plugged into the connector 200 on the circuit board 9 to achieve connection. Multiple floating sub-water-cooled plates 5 extend into the two metal housings 6, respectively, and can contact the optical module 100 to assist in heat dissipation. The metal housing 6 has multiple openings 62 on the side near the floating sub-water-cooled plates 5, each opening 62 corresponding to a different floating sub-water-cooled plate 5, allowing the floating sub-water-cooled plates 5 to extend into the receiving space 61 through the openings 62 of the metal housing 6, and enabling the floating sub-water-cooled plates 5 to contact the optical module 100.

[0035] Each of the multiple floating sub-water-cooled plates 5 is connected to the main water-cooled plate 4 via two adapters 7. Optionally, the two adapters 7 connected to each floating sub-water-cooled plate 5 are located near both ends of the floating sub-water-cooled plate 5, and each floating sub-water-cooled plate 5 is provided with four elastic elements 8 at its four corners. This allows the adapters 7 and elastic elements 8 to be optionally configured to provide stable support and optional floating effect. The adapter 7 may be a hollow cylinder with a through hole 75 inside. The adapter 7 connects the floating sub-water-cooled plate 5 and the main water-cooled plate 4, allowing the floating sub-water-cooled plate 5 and the main water-cooled plate 4 to communicate through the through hole 75. Coolant is delivered to the main water-cooled plate 4 through the inlet 2, and then to the floating sub-water-cooled plate 5 through the adapter 7. After heat exchange, the coolant is output through another adapter 7, and then discharged outward through the main water-cooled plate 4 and the outlet 3. Multiple elastic members 8 elastically abut against the multiple floating sub-water-cooled plates 5 to provide positive pressure, ensuring that the floating sub-water-cooled plates 5 remain in contact with the optical module 100 during vertical movement. After the optical module 100 is inserted, the floating sub-water-cooled plates 5 can move up and down, thus providing a floating (moving) function.

[0036] The adapter 7 is disposed on the floating sub-water cooling plate 5. In this embodiment, the adapter 7 is integrally formed on the floating sub-water cooling plate 5, and the adapter 7 has a plug-in portion 71 (e.g., Figures 8 to 10 As shown), the insertion part 71 is a hollow cylinder, and a through hole 75 is provided inside the insertion part 71.

The floating sub-water-cooled plate 5 and the main water-cooled plate 4 can be connected through the through hole 75, and the plug-in part 71 of the adapter 7 can move up and down in the through hole 45, so that the floating sub-water-cooled plate 5 can move up and down, thus providing a floating (moving) function. In addition, a sealing ring 73 can be provided between the plug-in part 71 of the adapter 7 and the main water-cooled plate 4 to improve the sealing between the adapter 7 and the main water-cooled plate 4, so as to provide a sealing function when the floating sub-water-cooled plate 5 floats up and down, thus preventing water leakage.

[0037] In another embodiment, the multiple floating sub-water-cooled plates 5 can also be disposed only above or below the main water-cooled plate 4. That is, the multiple floating sub-water-cooled plates 5 can be disposed only above or below the main water-cooled plate 4. The multiple floating sub-water-cooled plates 5 are disposed only on one side of the main water-cooled plate 4. Multiple elastic members 8 are respectively provided between the multiple floating sub-water-cooled plates 5 and the main water-cooled plate 4, so that the multiple floating sub-water-cooled plates 5 are respectively floatingly disposed between themselves and the main water-cooled plate 4. Each of the multiple floating sub-water-cooled plates 5 is connected to the main water-cooled plate 4 by two adapters 7. A through hole 75 is formed in the adapter 7.
