Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of optical transceiver module and optical transceiver module socket, especially, a heat dissipation structure of optical transceiver module and optical transceiver module socket. BACKGROUND

[0002] In the field of optical communication, the transmission rate of optical transceiver module is constantly improved, and the power of optical transceiver module operation is also increased, so that the optical transceiver module often works at high temperature. In order to avoid high working temperature, some optical transceiver modules currently have heat dissipation fins on the module shell or the shell of the optical transceiver module socket, in order to effectively dissipate the heat generated inside the optical transceiver module during operation. However, the simple heat dissipation fins have gradually failed to meet the use scenario of constantly improving transmission rate, causing design bottleneck of optical transceiver module or optical transceiver module socket. SUMMARY

[0003] In view of the problems in the background art, the purpose of the utility model is to provide an optical transceiver module socket shell, which uses liquid cooling parts to effectively absorb heat.

[0004] According to an embodiment of the utility model, an optical transceiver module socket shell includes a shell body and a liquid cooling part. The shell body forms a module slot. The liquid cooling part has a flow channel structure and an inlet and an outlet communicating with the flow channel structure. The liquid cooling part is fixedly arranged in the shell body and exposed in the module slot. In this way, when an optical transceiver module is inserted into the module slot, the liquid cooling part can contact the optical transceiver module to absorb the heat generated by the optical transceiver module during operation. In practice, a working fluid flows through the liquid cooling part through the inlet and the outlet to carry away the heat absorbed by the liquid cooling part, thereby achieving the effect of heat dissipation of the optical transceiver module.

[0005] Another purpose of the utility model is to provide an optical transceiver module, which has a flat heat-conducting surface and uses the heat-conducting surface to conduct the heat generated during operation to the outside.

[0006] According to an embodiment of the utility model, a transceiver module includes a module shell and a plate edge connector. The module shell has a length direction, and the module shell includes a main shell and two vertical plates. The main shell has a flat heat-conducting surface, and the two vertical plates protrude from the flat heat-conducting surface. The two vertical plates extend parallel to the length direction and are located on opposite sides of the main shell. A structureless space is formed between the two vertical plates and the flat heat-conducting surface. The plate edge connector is exposed on one side of the module shell in the length direction. When the transceiver module is inserted into a transceiver module socket, the flat heat-conducting surface of the transceiver module is thermally coupled with a heat exchanger of the transceiver module socket, so that the transceiver module can conduct heat generated during operation to the heat exchanger through the flat heat-conducting surface, thereby achieving the effect of heat dissipation.

[0007] Another purpose of the utility model is to provide a transceiver module combination, which includes a transceiver module socket having the aforementioned transceiver module socket shell, and a transceiver module matched with the transceiver module socket. Therefore, when the transceiver module is inserted into the transceiver module socket, the transceiver module socket can use a liquid cooling member to efficiently absorb heat generated during operation of the transceiver module.

[0008] According to an embodiment of the utility model, a transceiver module combination includes a transceiver module socket and a transceiver module. The transceiver module socket includes a connector socket and the aforementioned transceiver module socket shell. The connector socket is arranged in the module slot. The transceiver module includes a module shell and a plate edge connector. The module shell includes a main shell, and the main shell has a flat heat-conducting surface. The transceiver module is inserted into the module slot, so that the plate edge connector is inserted into the connector socket, and the flat heat-conducting surface contacts the liquid cooling member in the module slot. Therefore, heat generated during operation of the transceiver module can be conducted to the liquid cooling member through the flat heat-conducting surface. In addition, in practice, a working fluid flows through the liquid cooling member through the inlet and the outlet of the liquid cooling member to take away the heat absorbed by the liquid cooling member, thereby achieving the effect of heat dissipation for the transceiver module.

[0097] The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, etc., are only the directions referring to the attached drawings. The prefix words of the component names, such as first, second, etc., are only for distinguishing the components, facilitating the description, and do not impose other restrictions on the components. The components with the same prefix words in the embodiments do not necessarily correspond to each other. The correspondence of the components in the embodiments should be determined according to the specific structure described in the embodiments.

[0098] Please refer to Figure 1 , Figure 2 , Figure 3 . The optical transceiver module assembly 1 according to a first embodiment includes an optical transceiver module 12 and an optical transceiver module socket 14. The optical transceiver module socket 14 includes an optical transceiver module socket housing 142, a connector socket 144, and a circuit board 146. The optical transceiver module socket housing 142 includes a housing body 1422 and a liquid cooling member 1424. The housing body 1422 forms a module slot 1422a having a length direction 1422b (indicated by a double-headed arrow in the figure) and having a slot entrance 1422c in the length direction 1422b. The liquid cooling member 1424 is fixedly arranged in the housing body 1422 and exposed in the module slot 1422a. The connector socket 144 is electrically connected and fixed to the circuit board 146. The housing body 1422 is fixed to the circuit board 146, so that the connector socket 144 is located in the module slot 1422a. The optical transceiver module 12 can be inserted into the module slot 1422a from the slot entrance 1422c parallel to the length direction 1422b, so as to be connected with the connector socket 144 and contact the liquid cooling member 1424; thereby, the heat generated by the optical transceiver module 12 during operation can be conducted to the liquid cooling member 1424 (equivalent to a heat exchanger), achieving the heat dissipation effect.

[0099] Please refer to Figure 4 and Figure 5The liquid cooling component 1424 includes a base 1424a and a top cover 1424b. The base 1424a forms a flow channel structure 1424c and an inlet 1424d and an outlet 1424e communicating with the flow channel structure 1424c. The top cover 1424b is fixed to the base 1424a (by means of, but not limited to, tight fitting and / or soldering) to cover the flow channel structure 1424c. The working fluid (not shown in the figure) flows through the flow channel structure 1424c via the inlet 1424d and the outlet 1424e to remove the heat absorbed by the base 1424a. The flow channel structure 1424c includes a first flow channel portion 1424f and a second flow channel portion 1424g (both indicated by dashed boxes in the figure), both extending parallel to the length direction 1422b. The inlet 1424d, the first flow channel section 1424f, the second flow channel section 1424g, and the outlet 1424e are connected sequentially. Furthermore, the first flow channel section 1424f includes two sub-flow channels 1424h, extending parallel to the length direction 1422b and connected in parallel; the second flow channel section 1424g is similar, and will not be described further. This structural configuration facilitates the smooth flow of the working fluid through the flow channel structure 1424c, thereby suppressing the generation of localized hot spots in the liquid-cooled component 1424.

[0100] Furthermore, the optical transceiver module socket housing 142 also includes two transmission pipes 1426a and 1426b, which are fixedly connected to the inlet 1424d and the outlet 1424e, respectively, facilitating connection to the manifold of an external cooling system. For example, a device with an optical transceiver module socket 14 is installed in a cabinet equipped with a cooling system, and the manifold of the cooling system is fixed to the bracket of the cabinet and connected to the transmission pipes 1426a and 1426b (for example, a flexible hose connecting the manifold is fitted onto the transmission pipes 1426a and 1426b). In the first embodiment, there are two oppositely arranged grooves 1424i on the inner wall of the inlet 1424d, and the corresponding transmission pipe 1426a is tightly fitted into these two grooves 1424i. Similarly, there are also two oppositely arranged grooves 1424j on the inner wall of the outlet 1424e, and the corresponding transmission pipe 1426b is tightly fitted into these two grooves 1424j.

[0101] like Figure 6 and Figure 7 As shown, the shell body 1422 includes a first sliding hook 1422d and a second sliding hook 1422e within the module slot 1422a, located on both sides of the shell body 1422 relative to the length direction 1422b. In the first embodiment, both the first sliding hook 1422d and the second sliding hook 1422e are formed by bending and extending from the upper sidewall of the shell body 1422, but this is not a limitation in practice. For example, if the actual product structure allows, the first sliding hook 1422d and the second sliding hook 1422e can also be formed by bending and extending from the opposite sidewall of the shell body 1422, respectively. Figure 3 and Figure 4As shown, a first groove 1424k and a second groove 1424m are formed on both sides of the liquid cooling component 1424 (base 1424a). The liquid cooling component 1424 slides into and hooks the first groove 1424k and the second groove 1424m respectively through the first hook 1422d and the second hook 1422e to fix it in the shell body 1422.

[0102] Furthermore, the connection between the first sliding hook 1422d and the first sliding groove 1424k is as follows: Figure 8 As shown (this is a side view of the liquid cooling component 1424, where the outline of the first sliding hook 1422d is drawn with dashed lines, and the insertion port 1422c is located on the left). The first sliding groove 1424k is a T-shaped groove, having a first inlet end 1425a, a first closed end 1425b, and a second closed end 1425c. During the assembly of the liquid cooling component 1424 and the housing body 1422, the liquid cooling component 1424 is moved so that the first sliding hook 1422d enters the first sliding groove 1424k from the first inlet end 1425a and slides to the first closed end 1425b in a sliding direction D1 (indicated by an arrow in the figure). After the first sliding hook 1422d engages with the first sliding groove 1424k, as shown... Figure 9 As shown. Furthermore, the connection between the second sliding hook 1422e and the second sliding groove 1424m is as follows: Figure 10 As shown (this is another side view of the liquid cooling component 1424, where the outline of the second sliding hook 1422e is drawn with dashed lines, and the insertion port 1422c is located on the right side). The second sliding groove 1424m is a T-shaped groove, having a second inlet end 1425d, a third closed end 1425e, and a fourth closed end 1425f. During the assembly of the liquid cooling component 1424 and the housing body 1422, the liquid cooling component 1424 is moved so that the second sliding hook 1422e enters the second sliding groove 1424m from the second inlet end 1425d and slides to the third closed end 1425e in the sliding direction D1. After the second sliding hook 1422e is engaged with the second sliding groove 1424m, as... Figure 11 As shown. At this point, the liquid cooling component 1424 reaches the installation position (relative to the housing body 1422).

[0103] Furthermore, in the first embodiment, as Figure 6 As shown, the shell body 1422 also includes a stop spring 1422f (e.g., but not limited to, implemented as a flexible cantilever structure) within the module slot 1422a; as Figure 4 As shown, the liquid cooling component 1424 (base 1424a) also forms a slot 1424n. For example... Figure 9As shown, after the liquid cooling component 1424 reaches the installation position, the stop spring 1422f engages with the slot 1424n to prevent the liquid cooling component 1424 from sliding relative to the housing body 1422 in a direction opposite to the sliding direction D1 (by the free end of the stop spring 1422f abutting against the side wall of the slot 1424n). At this time, the liquid cooling component 1424 remains fixed to the housing body 1422.

[0104] like Figure 1 and Figure 3 As shown, the liquid cooling component 1424 has a first flat thermally conductive surface 1424p (implemented on the bottom surface of the base 1424a), which protrudes into the module slot 1422a. The optical transceiver module 12 includes a module housing 122 and a board edge connector 124. The module housing 122 includes a main housing 1222 and two vertical plates 1224. The main housing 1222 has a third flat thermally conductive surface 1222a, from which the two vertical plates 1224 protrude. The two vertical plates 1224 extend parallel to the length direction of the module housing 122 (the same as the length direction 1422b) and are located on opposite sides of the main housing 1222. A structureless space 1226 (represented by dashed squares) is formed between the two vertical plates 1224 and the third flat thermally conductive surface 1222a. Figure 1 (In the middle). The edge connector 124 protrudes from one side of the module housing 122 along its length. The optical transceiver module 12 is inserted into the module slot 1422a, so that the liquid cooler 1424 enters the unstructured space 1226 between the two vertical plates 1224. The edge connector 124 is inserted into the connector socket 144 of the optical transceiver module socket 14, and the third flat thermally conductive surface 1222a contacts the first flat thermally conductive surface 1424p of the liquid cooler 1424 within the module slot 1422a. This large-area surface contact improves the efficiency of the liquid cooler 1424 in absorbing heat from the optical transceiver module 12. Alternatively, in practice, the module housing 122 may not have the vertical plates 1224.

[0105] In addition, such as Figure 1 and Figure 4 As shown, the inlet 1424d and outlet 1424e of the flow channel structure 1424c of the liquid cooler 1424 are both located on the side of the liquid cooler 1424 along the length direction 1422b near the insertion port 1422c; in other words, the inlet 1424d and outlet 1424e are located on the front side of the optical transceiver module socket 14 (defined as the side near the insertion port 1422c). In the first embodiment, the housing body 1422 has an opening 1422g on the other side opposite to the insertion port 1422c, and the liquid cooler 1424 can be rotated 180 degrees as needed to be installed into the housing body 1422, such as... Figure 12As shown (wherein, the lengths of transmission pipes 1426a' and 1426b' in the figure are increased (relative to transmission pipes 1426a and 1426b) to accommodate this configuration, i.e., increased to the point that they can protrude from the housing body 1422 through the opening 1422g for easy connection to the manifold of the external cooling system). The installation method is described below.

[0106] Please see Figure 3 and Figure 4 The liquid-cooled component 1424 (its base 1424a) also forms a slot 1424q. For example... Figure 13 As shown (which is a side view of the liquid cooling component 1424, where the outline of the first sliding hook 1422d is drawn with dashed lines; the insertion port 1422c is located on the left side but is not shown), during the assembly of the liquid cooling component 1424 and the housing body 1422, the liquid cooling component 1424 is moved so that the first sliding hook 1422d enters the second sliding groove 1424m from the second inlet end 1425d, and slides in the sliding direction D1 to the fourth closed end 1425f, causing the stop spring 1422f to engage in the slot 1424q. After the first sliding hook 1422d is connected to the second sliding groove 1424m, as... Figure 14 As shown. Also, as... Figure 15 As shown (this is another side view of the liquid cooling component 1424, where the outline of the second sliding hook 1422e is drawn with dashed lines; the insertion port 1422c is located on the right side but is not shown), during the assembly of the liquid cooling component 1424 and the housing body 1422, the liquid cooling component 1424 is moved so that the second sliding hook 1422e enters the first sliding groove 1424k from the first inlet end 1425a and slides to the second closed end 1425c in the sliding direction D1. After the second sliding hook 1422e is engaged with the first sliding groove 1424k, as... Figure 16 As shown. At this point, the liquid cooling component 1424 reaches the installation position (relative to the housing body 1422). The inlet 1424d and outlet 1424e of the flow channel structure 1424c of the liquid cooling component 1424 are both located on the side of the liquid cooling component 1424 away from the insertion port 1422c in the length direction 1422b; in other words, the inlet 1424d and outlet 1424e are located on the rear side of the optical transceiver module socket 14 (defined as the side away from the insertion port 1422c). Therefore, at least the liquid cooling component 1424 itself can be used for installation in different directions (to the housing body 1422), increasing the versatility of the liquid cooling component 1424 and reducing manufacturing costs.

[0107] In addition, in the first embodiment, the first sliding hook 1422d and the second sliding hook 1422e are arranged on the shell body 1422, and the first sliding groove 1424k and the second sliding groove 1424m are arranged on the liquid cooling member 1424; however, the implementation is not limited thereto. For example, the foregoing structure can be arranged reversely, and the same effect can be achieved, and details are not described herein again. Similarly, the structure of the stop spring 1422f and the clamping groove 1424n, 1424q in the first embodiment can also be arranged reversely, and the same effect can be achieved, and details are not described herein again.

[0108] In addition, in the first embodiment, the optical transceiver module socket 14 is taken as an example for description, which provides a single slot (i.e., the module slot 1422a); however, the implementation is not limited thereto. For example, please refer to Figure 17 According to a second embodiment, the optical transceiver module socket 24 is a 2x4 socket, which provides eight module slots 2422a (one of which is shown in the figure). In terms of structure and logic, the optical transceiver module socket 24 is equivalent to the combination of eight optical transceiver module sockets 14 (arranged in two rows), and therefore, for other descriptions of the optical transceiver module socket 24, please refer to the foregoing descriptions of the optical transceiver module socket 14 and its variants. In brief, the optical transceiver module socket 24 comprises an optical transceiver module socket shell 242, eight connector sockets 244, and a circuit board 246. The eight connector sockets 244 are electrically connected and fixed on the circuit board 246; wherein, every two connector sockets 244 (vertically adjacent) are structurally integrated into one connector seat body, for example, the outline of one connector seat body is shown in the figure (shown by a dashed line in the figure). The optical transceiver module socket shell 242 comprises a shell body 2422 and eight liquid cooling members 2424 (one of which is shown in the figure). The shell body 2422 forms the eight module slots 2422a and is fixed on the circuit board 246, so that the eight connector sockets 244 are located inside the optical transceiver module socket shell 242 and respectively exposed in the eight module slots 2422a. The eight liquid cooling members 2424 are fixedly arranged in the shell body 2422 and respectively exposed in the eight module slots 1422a. In actual application, the eight module slots 2422a can be inserted into an optical transceiver module (for example, the optical transceiver module 12 described hereinbefore), and details are not described herein again.

[0109] In addition, in the optical transceiver module socket 24, (as shown in the figure) Figure 17From the perspective of [the user's perspective], since the circuit board 246 is located on the lower side of the housing body 2422, the upper row of connector sockets 244 structurally passes through the lower row of module slots 2422a, making it generally difficult for the inlet and outlet of the flow channel structure of the lower row of liquid cooling components 2424 to be set rearward. In the second embodiment, the inlet and outlet of the flow channel structure of both the upper and lower rows of liquid cooling components 2424 are set forward, but this is not a limitation in practice. For example, the inlet and outlet of the flow channel structure of the upper row of liquid cooling components 2424 can be set rearward; in this case, an opening structure needs to be formed at the corresponding rear side of the housing body 2422 to allow it to pass through. In addition, in practice, the flow channel structures of adjacent liquid cooling components 2424 in the same row can be designed in series.

[0110] For example, please see Figure 18 and Figure 19 According to a third embodiment, the optical transceiver module socket 34 is an 8×2 socket, providing a total of 16 module slots 3422a (selectively labeled in the figure). Structurally, the optical transceiver module socket 24 is equivalent to a combination of 16 optical transceiver module sockets 14 (vertically arranged in four rows, two per row). Therefore, for further descriptions of the optical transceiver module socket 34, please refer directly to the preceding descriptions of the optical transceiver module socket 14 and its variations. In simple terms, the optical transceiver module socket 34 includes an optical transceiver module socket housing 342, 16 connector sockets 344 (selectively shown in dashed lines in the figure), and a circuit board 346. The 16 connector sockets 344 are individually electrically connected and fixed to the circuit board 346. The optical transceiver module socket housing 342 includes a housing body 3422 and 16 liquid cooling components 3424 (selectively labeled in the figure). The housing body 3422 forms the 16 module slots 3422a and is fixed to the circuit board 346, such that the 16 connector sockets 344 are located inside the optical transceiver module socket housing 342 and are exposed in the 16 module slots 3422a respectively. In practical applications, each of the 16 module slots 3422a can be used to insert an optical transceiver module (such as the optical transceiver module 12 mentioned above), which will not be described further.

[0111] Additionally, in the optical transceiver module socket 34, (with Figure 18 From a certain perspective, the circuit board 346 is located on the rear side of the housing body 3422, allowing all 16 module slots 3422a to be directly fixed to the circuit board 346 without passing through other module slots 3422a. Therefore, the inlets and outlets of the flow channel structure of the 16 liquid cooling components 3424 can be changed to face rearward; at this time, an opening structure needs to be formed on the rear side of the housing body 3422 and the corresponding location of the circuit board 346 (e.g., Figure 19 (As shown) to allow passage. Furthermore, in practice, the flow channel structures of adjacent liquid cooling components 3424 in the same row can be designed in series. Also, the flow channel structures of vertically adjacent liquid cooling components 3424 can be designed in series as needed.

[0112] Please seeFigure 20 、 Figure 21 、 Figure 22 The optical transceiver module assembly 5 according to a fourth embodiment comprises an optical transceiver module 52 and an optical transceiver module socket 54. The optical transceiver module socket 54 comprises a socket housing 542, a connector socket 544 and a circuit board 546. The socket housing 542 comprises a housing body 5422 and a liquid cooling member 5424. The housing body 5422 forms a module slot 5422a having a length direction 5422b (indicated by a double-headed arrow in the figure) and an insertion opening 5422c in the length direction 5422b. The liquid cooling member 5424 is fixedly arranged in the housing body 5422 and exposed in the module slot 5422a. The connector socket 544 is electrically connected and fixed to the circuit board 546. The housing body 5422 is fixed to the circuit board 546 so that the connector socket 544 is located in the module slot 5422a. The optical transceiver module 52 can be inserted into the module slot 5422a from the insertion opening 5422c parallel to the length direction 5422b to engage with the connector socket 544 and contact the liquid cooling member 5424; thereby, the heat generated by the optical transceiver module 52 during operation can be conducted to the liquid cooling member 5424 (i.e. equivalent to a heat exchanger) to achieve heat dissipation effect.

[0113] Please refer to Figure 23 The liquid cooling member 5424 comprises a base 5424a and an upper cover 5424b. The base 5424a forms a flow channel structure 5424c, an inlet 5424d and an outlet 5424e communicating with the flow channel structure 5424c, and the upper cover 5424b is fixed to the base 5424a (by means such as but not limited to tight fit and / or soldering) to cover the flow channel structure 5424c. A working fluid (not shown in the figure) flows through the flow channel structure 5424c via the inlet 5424d and the outlet 5424e to take away the heat absorbed by the base 5424a. Compared with the liquid cooling member 1424 in the first embodiment, the liquid cooling member 5424 in the present embodiment is basically the same in structure as the liquid cooling member 1424 (in the first embodiment) except that the positions of the inlet 5424d and the outlet 5424e are different. Therefore, for other descriptions about the liquid cooling member 5424 itself, please refer directly to the relevant descriptions of the liquid cooling member 1424 in the foregoing, which will not be repeated here. In the present embodiment, the inlet 5424d and the outlet 5424e are located on opposite sides of the liquid cooling member 5424 perpendicular to the length direction 5422b; the side walls of the housing body 5422 corresponding to the inlet 5424d and the outlet 5424e form openings for them to pass through.

[0114] In addition, in the present embodiment, the combination of the liquid cooling member 5424 and the housing body 5422 is basically the same as the combination of the liquid cooling member 1424 and the housing body 1422 in the foregoing (in the first embodiment), which will not be repeated here.

[0115] In addition, in the present embodiment, as shown in Figure 20 , Figure 21 , Figure 22 , the liquid cooling member 5424 has a first flat heat-conducting surface 5424f (implemented as the bottom surface of the base 5424a) exposed in the module slot 5422a. The optical transceiver module 52 includes a module housing 522 and a board edge connector 524. The module housing 522 has a third flat heat-conducting surface 522a, above which there is no other structure, forming an unstructured space 522b (indicated by a dashed square in Figure 20 ). The board edge connector 524 is exposed on one side of the module housing 522 in the length direction of the module housing 522 (parallel to the length direction 5422b of the module slot 5422a). The optical transceiver module 52 is inserted into the module slot 5422a, so that the liquid cooling member 5424 enters the unstructured space 522b above the third flat heat-conducting surface 522a, the board edge connector 524 is inserted into the connector socket 544 of the optical transceiver module socket 54, and the third flat heat-conducting surface 522a contacts the first flat heat-conducting surface 5424f of the liquid cooling member 5424 in the module slot 5422a. This large-area surface contact can improve the efficiency of heat absorption from the optical transceiver module 52 by the liquid cooling member 5424. In addition, in practice, under the condition that there is sufficient space between the liquid cooling member 5424 and the housing body 5422 (for example), the module housing 522 can also have a vertical plate, so that the overall appearance is similar to that of the module housing 122 (in the first embodiment).

[0116] Please refer to Figures 24 to 26The optical transceiver module receptacle 64 according to a fifth embodiment is an 8x2 receptacle, providing 16 module slots 6422a (indicated in the figure alternatively). The optical transceiver module receptacle 64 comprises an optical transceiver module receptacle housing 642, 16 connector receptacles 644 (indicated in the figure alternatively) and a circuit board 646. The optical transceiver module receptacle housing 642 comprises a housing body 6422 and 8 liquid coolers 6424. The housing body 6422 forms the aforementioned 16 module slots 6422a. Each module slot 6422a has a length direction 6422b (indicated in the figure by a double-headed arrow) and has an insertion opening 6422c in the length direction 6422b. Each liquid cooler 6424 corresponds to two module slots 6422a (e.g. a first module slot 6423a and a second module slot 6423b arranged in parallel and adjacent to each other). The liquid cooler 6424 is fixedly arranged in the housing body 6422 and exposed in the corresponding module slot 6422a. The connector receptacles 644 are electrically connected and fixed to the circuit board 646. The housing body 6422 is fixed to the circuit board 646, so that the connector receptacles 644 are located in the module slots 6422a. An optical transceiver module (e.g. the optical transceiver module 52 in the fourth embodiment) can be inserted into the module slot 6422a from the insertion opening 6422c parallel to the length direction 6422b, to engage and contact the corresponding connector receptacle 644 and the corresponding liquid cooler 6424; thereby, the heat generated by the optical transceiver module during operation can be conducted to the corresponding liquid cooler 6424 (i.e. equivalent to a heat exchanger), achieving the heat dissipation effect.

[0117] Please refer to Figure 25 , Figure 26 , Figure 27 , Figure 28 . Further, the liquid cooler 6424 comprises a base 6424a and an upper cover 6424b. The base 6424a forms a flow channel structure 6424c and an inlet 6424d and an outlet 6424e in communication with the flow channel structure 6424c, and the upper cover 6424b is fixed to the base 6424a (by means such as but not limited to tight fit and / or soldering) to cover the flow channel structure 6424c. The working fluid (not shown in the figure) flows through the flow channel structure 6424c through the inlet 6424d and the outlet 6424e to take away the heat absorbed by the base 6424a. As a whole, the liquid cooler 6424 comprises a first structural part 6425a, a second structural part 6425b and a structural connecting part 6425c (in the figure alternatively indicated as a first connecting part 6425a and a second connecting part 6425b). Figure 25 and Figure 26(The approximate extent of each part is indicated by dashed squares). The first structural part 6425a and the second structural part 6425b are separate but connected by a structural connecting part 6425c. The first structural part 6425a, the second structural part 6425b, and the structural connecting part 6425c together form the flow channel structure 6424c. The first structural part 6425a (the first flat thermally conductive surface 6425d) is exposed within the first module slot 6423a, and the second structural part 6425b (the second flat thermally conductive surface 6425e) is exposed within the second module slot 6423b (see [reference]). Figure 24 This allows the third flat thermally conductive surface 522a of the optical transceiver module 52 inserted into the first module slot 6423a or the second module slot 6423b to be (see reference). Figure 20 It can correspondingly contact the first flat thermally conductive surface 6425d or the second flat thermally conductive surface 6425e.

[0118] Furthermore, the flow channel structure 6424c includes a first flow channel portion 6424f, a second flow channel portion 6424g, a third flow channel portion 6424h, and a fourth flow channel portion 6424i (in Figure 28 (The extent of each section is indicated by a dashed box), all extending parallel to the length direction 6422b. The first structural portion 6425a forms the first flow channel portion 6424f and the second flow channel portion 6424g, corresponding to the first module slot 6423a; the second structural portion 6425b forms the third flow channel portion 6424h and the fourth flow channel portion 6424i, corresponding to the second module slot 6423b. The second flow channel portion 6424g and the third flow channel portion 6424h are connected via a structural connection portion 6425c. The inlet 6424d, the first flow channel portion 6424f, the second flow channel portion 6424g, the third flow channel portion 6424h, the fourth flow channel portion 6424i, and the outlet 6424e are connected sequentially. (Similar to the flow channel structure 1424c in the first embodiment above) The first flow channel portion 6424f, the second flow channel portion 6424g, the third flow channel portion 6424h, and the fourth flow channel portion 6424i each include two sub-flow channels (not shown). For related descriptions, please refer directly to the previous description of the sub-flow channel 1424h in flow channel structure 1424c; further details will not be provided here. Additionally, the flow channel structures of adjacent liquid cooling components 6424 may also be designed in series, depending on requirements.

[0119] Furthermore, the liquid cooler 6424 is logically equivalent to two liquid coolers 5424 (in the fourth embodiment) (see reference). Figure 21 and Figure 23) of the liquid cooling member 6424. For further description of the liquid cooling member 6424 itself, please refer to the relevant description of the liquid cooling member 5424 above. In addition, the combination of the liquid cooling member 6424 and the shell body 6422 is substantially similar to the combination of the liquid cooling member 5424 and the shell body 5422 above, so for further description of the combination of the liquid cooling member 6424 and the shell body 6422, please refer to the relevant description of the combination of the liquid cooling member 5424 and the shell body 5422 above. In this embodiment, as shown in Figure 25 the shell body 6422 has a partition wall 6422d (in this embodiment, realized by two parallel plates) between the first module slot 6423a and the second module slot 6423b and has a recess 6422e. The structural connecting portion 6425c is inserted into the recess 6422e. In practice, the partition wall 6422d can provide the liquid cooling member 6424 with certain effective (vertical direction) support through the recess 6422e.

[0120] Please refer to Figure 29 and Figure 30 . The optical transceiver module socket 74 according to a sixth embodiment is similar in structure to the optical transceiver module socket 64 (of the fifth embodiment), so the optical transceiver module socket 74 basically uses the element symbols of the optical transceiver module socket 64. For further description of the optical transceiver module socket 74, please refer to the relevant description of the optical transceiver module socket 64 above. The main difference is that in the optical transceiver module socket housing 742 of the optical transceiver module socket 74, the combination of the liquid cooling member 7424 and the shell body 7422 does not use structures such as hooks and grooves (such as the first hook 1422d and the first groove 1424k in the first embodiment). Compared with the liquid cooling member 6424 (of the fifth embodiment), the liquid cooling member 7424 further includes an intermediate connecting portion 6425f. The first structural portion 6425a and the second structural portion 6425b are separated and connected through the structural connecting portion 6425c and the intermediate connecting portion 6425f, and the structural connecting portion 6425c and the intermediate connecting portion 6425f are separated. The partition wall 6422d' of the shell body 7422 further includes another recess 6422f, and the intermediate connecting portion 6425f is inserted into the recess 6422f. In this embodiment, the recesses 6422e, 6422f, and the openings 6422g (for the inlet 6424d and the outlet 6424e of the liquid cooling member 7424 to pass through) on the side wall are not arranged in a non-collinear manner, so they can collectively provide effective (vertical direction) support for the liquid cooling member 7424; in addition, the recesses 6422e, 6422f also limit the liquid cooling member 7424 in the direction parallel to the length direction 6422b (i.e., horizontal direction). In this way, the liquid cooling member 7424 can be stably and fixedly arranged in the shell body 7422.

[0121] Please refer to Figure 31The optical transceiver module socket 84 according to a seventh embodiment is an 8x4 socket. The shell body 8422 of the optical transceiver module socket housing 842 of the optical transceiver module socket 84 forms 32 module slots 8422a (indicated in the figure) and is fixed on the circuit board 846. A connector socket (electrically connected and fixed on the circuit board 846; not shown in the figure) is arranged in each module slot 8422a. The optical transceiver module socket 84 is similar in structure and logic to the optical transceiver module socket 74 (of the sixth embodiment). Therefore, for the other descriptions of the optical transceiver module socket 84, please refer to the relevant descriptions of the optical transceiver module socket 74 above. The main difference is that each liquid cooling member 8424 of the optical transceiver module socket housing 842 simultaneously provides heat exchange function for four module slots 8422a (the original arrangement position of the liquid cooling member 8424 shown in the figure is indicated by a dashed line). The liquid cooling member 8424 still has a single inlet 8424a and a single outlet 8424b for the working fluid to flow through the internal flow channel structure. In addition, in the module slot 8422a, the shell body 8422 further includes a plurality of elastic pieces 8422b (arranged on the lower side wall of the module slot 8422a relative to the liquid cooling member 8424), so that the optical transceiver module (such as the optical transceiver module 52 in the figure) inserted into the module slot 8422a is pushed by the plurality of elastic pieces 8422b towards the liquid cooling member 8424, so that the flat heat-conducting surface (such as the third flat heat-conducting surface 522a of the optical transceiver module 52) of the optical transceiver module is kept in close contact with the flat heat-conducting surface 8424c of the bottom of the liquid cooling member 8424, ensuring heat exchange between the optical transceiver module and the liquid cooling member 8424. Figure 20

[0122] In addition, in the above-mentioned embodiments, the structure design of the optical transceiver module 12, 52 and the optical transceiver module socket 14, 24, 34, 54, 64, 74, 84 can be mutually referenced and applied in practice, and no further description is given.

[0123] The above only describes the preferred embodiments of the present application. Any changes and modifications made within the scope of the present application should be included in the scope of the present application.​
