Fig. 1 is a schematic structural diagram of a data center according to an embodiment of the present application. As shown in fig. 1, in some embodiments, the data center 1 includes a plurality of electronic devices 10. The electronic device 10 may be of various kinds, and may be, for example, a server 11, a communication device 12, or a terminal 13. Data transfer can be realized among the server 11, the communication device 12 and the terminal 13. The present application is not limited in terms of the implementation of the electronic device 10.

The electronic device provided in the embodiment of the present application is described below by taking a server as an example.

Fig. 2 is a schematic structural diagram of an electronic device according to an embodiment of the present application. As shown in fig. 2, in some embodiments, the server 11 includes a cabinet 110 and an optical module 120. The optical module 120 can be installed in the cabinet 110 in a pluggable manner.

The optical module 120 is used as an optoelectronic device for photoelectric and electro-optical conversion in the information communication technology (information communications technology, ICT) industry, and is a core device for optical communication. The optical modules 120 cooperate to complete data exchange between servers 11 at different levels in the data center 1. The optical module 120 may be a long-range communication module, a short-range communication module, or the like. The long-range communication module comprises a coherent communication module, and the short-range communication module comprises a banner communication module. The embodiment of the present application does not particularly limit the specific form of the optical communication apparatus.

Fig. 3 is a schematic structural diagram of an optical module according to an embodiment of the present application. As shown in fig. 3, in one implementation, the light module 120 includes a first circuit board 121, an upper case 122, a lower case 123, and a handle bar 124. The upper case 122 and the lower case 123 are disposed opposite to each other and fixedly connected to each other, and together define an accommodating space. The first circuit board 121 is disposed in the receiving space. The handle bar 124 is U-shaped, and an opening of the handle bar 124 faces the upper case 122 and is fixedly connected with the upper case 122. In this way, the optical module 120 is plugged and unplugged by pushing and pulling the handle bar 124, so that the operation is more convenient.

As shown in fig. 3, in one implementation, the optical module 120 includes a connector 127 for enabling data transmission between the optical module 120 and other modules or devices.

As shown in fig. 3, in one implementation, the optical module 120 includes, in addition to the first circuit board 121, the upper case 122, the lower case 123, and the handle bar 124, a light emission sub-module (transmitter optical subassembly, TOSA) 125 and a light reception sub-assembly (receiver optical subassembly, ROSA) 126 disposed on the first circuit board 121. TOSAs and ROSAs are used to convert optical signals into electrical signals.

To achieve a pluggable connection of the optical module and the cabinet, as shown in fig. 4, in some embodiments, the cabinet 110 includes a cabinet body 111 and an optical cage 112. The optical cage 112 is disposed in the cabinet 111 and is fixedly connected with the cabinet 111. In one implementation, a support rod 110a is disposed in the cabinet 111, and the light cage 112 may be fixed to the support rod 110a by welding. Alternatively, the light cage 112 may be secured to the support bar 110a by fasteners, such as screws.

The cabinet 111 is used for protecting electronic devices disposed in the cabinet 110. The cabinet 111 may be a box-packed structure or a closed structure with a cabinet door. The cabinet 111 may have various shapes, such as a cube shape as shown in fig. 4, a cylindrical shape, or other irregular shapes, which are not limited in this application.

The optical cage 112 is disposed in the cabinet 111. As shown in fig. 4 and 5, the light cage 112 has a slot 1122 formed therein. In one implementation, the optical cage 112 has a cube structure, a first side 112c of the optical cage 112 facing the outside of the cabinet 111 is provided with a cavity 1120, and an extending direction of the cavity 1120 is parallel to a second bottom 111a of the cabinet 111 to form a slot 1122.

In one implementation, the connector 130 is disposed within the slot 1122 of the light cage 112. The connector 130 is used for insertion of the electrical connector 127 of the optical module 120.

As shown in fig. 3-5, the light module 120 can be removably disposed within the slot 1122 of the light cage 112. After the optical module 120 is inserted into the slot 1122 of the optical cage 112, the optical fiber at the tail of the optical module 120 is inserted into the connector 130 of the slot 1122 through the connector 127. In this way, the optical cage 112 not only can protect the optical module 120, but also can complete the electrical connection between the optical module 120 and the connector 130 in the optical cage 112, so as to realize the conversion between the optical signal in the optical module 120 and the electrical signal in the server 11, and complete the data transmission. It will be appreciated that, in view of the operation of inserting and extracting the connector 127 of the optical module 120 into and from the socket 1122, there is a certain gap between the socket 1122 and the connector 127 of the optical module 120 inserted into the socket 1122, so as to facilitate the insertion and extraction.

To increase the air flow between the slot of the light cage and the exterior of the light cage, and to facilitate heat dissipation, as shown in fig. 6, in one implementation, a plurality of vent holes 1124 are formed in the light cage 112. By forming the plurality of ventilation holes 1124 on each wall of the optical cage 112, not only can the weight of the optical cage 112 be reduced, but also the cost can be reduced.

When the optical module and the connector perform data transmission, devices on the first circuit board generate heat, and the heat is transferred to the upper shell and the lower shell. The heat is too high, which can cause the temperature of the optical module to be too high, and the devices inside the optical module are baked, so that the normal operation of the optical module is affected. With the continuous improvement of computing power and performance of the server, the heat dissipation requirement of the server is continuously improved.

In order to achieve efficient heat dissipation, as shown in fig. 7, in some embodiments, the cabinet 110 provided in the embodiments of the present application includes a heat conducting portion 113 in addition to a cabinet body 111 and an optical cage 112. The heat conducting part 113 is connected with the optical cage 112, and a part of the heat conducting part 113 is positioned in the slot 1122, and the other part is arranged outside the optical cage 112. It can be understood that the setting position of the heat conducting portion 113 may use the heating position of the optical module as a reference, so that the heat conducting portion 113 can be directly contacted with the heating position of the optical module, so as to improve the heat dissipation efficiency. And, the direct contact area between the heat conduction portion 113 and the optical module 120 is large, so that the effect of uniform temperature can be achieved.

In order to obtain a better heat dissipation effect, the surface of the heat conducting portion 113 contacting the optical cage 112 may be a smooth plane. In this way, the contact area between the heat conduction portion 113 and the optical cage 112 can be increased, which is beneficial to heat transfer, thereby improving heat dissipation efficiency.

In this way, after the optical module 120 is inserted into the optical cage 112, the optical module 120 can be in contact with the heat conduction portion 113, and heat generated by the optical module 120 can be transferred to the heat conduction portion 113. Compared with the heat transfer through the air, the cabinet 110 provided by the embodiment of the application is provided with the heat conducting part 113 extending into the slot 1122, and the heat of the optical module 120 is transmitted from the inside of the optical cage 112 to the outside of the optical cage 112, so that the purpose of improving the heat dissipation efficiency is achieved.

In order to ensure close contact between the light module 120 and the thermally conductive portion 113, in some embodiments, the relative positions of the thermally conductive portion 113 and the light cage 112 are set to have a certain initial compression.

As shown in fig. 7, in some embodiments, the cabinet 110 further includes a fixing structure 114, and the heat conducting portion 113 is fixedly connected to the optical cage 112 through the fixing structure 114.

To transfer heat away from the thermally conductive portion, in some embodiments, as shown in fig. 7, the cabinet 110 further includes: a heat spreader 115 and a heat sink 116. One end of the heat spreader 115 is connected to the heat conducting portion 113, and the other end is connected to the heat sink 116.

There are a number of possible implementations of the heat spreader 115. For example, the heat spreader 115 may be a heat pipe or a temperature plate. For another example, the heat spreader 115 may be a high thermal conductivity metal, such as copper. In this way, the heat pipe or the temperature equalization plate in the heat exchanger 115 provided in the embodiment of the present application can implement a liquid cooling heat dissipation scheme, and can meet the requirement of noise reduction while solving the high heat dissipation requirement, and can also reduce the power supply use efficiency (power usage effectiveness, PUE).

There are a variety of possible implementations of the heat sink 116. For example, the heat sink 116 may include a radiator or a regenerator. For another example, the heatsink 116 may also be a "keep-down module that derives heat from temperatures below the optical module".

There are various ways of connecting the heat spreader 115 to the heat sink 116. For example, the heat sink 116 may be located on the heat spreader 115. For another example, to increase the contact area between the heat sink 116 and the heat spreader 115, the heat sink 116 may also be located within the heat spreader 115 (as shown in fig. 11), as will be described in the following embodiments.

The heat conducting part has various realization modes, and the detailed description is provided below with reference to the accompanying drawings.

As shown in fig. 8, in one implementation, the outer portion of the optical cage 112 has a second surface 112a, and the second surface 112a has a first window 210 formed thereon, where the first window 210 is in communication with the slot 1122. The heat conductive portion 113 includes a second heat conductive portion 113a. The second heat conducting portion 113a includes a first boss 310, and the first boss 310 extends into the slot 1122 through the first window 210. The first boss 310 is fixedly coupled to the light cage 112 by the fixation structure 114. There are various implementations of the fixing structure 114. As shown in fig. 8, in one example, the securing structure 114 includes a hanger 114a and a fastener 114b. The lugs 114a are disposed on the light cage 112 and the fasteners 114b are disposed on the first bosses 310. In another example, the tab 114a is disposed on the first boss 310 and the catch 114b is disposed on the light cage 112. In another example, the fixing structure 114, the heat conducting portion 113, and the optical cage 112 may be a unitary structure. In yet another example, the securing structure 114 may also be other fasteners, such as screws, such as glue, for connecting two different parts. It is understood that the second surface 112a may be any surface of the light cage 112.

In order to ensure intimate contact between the light module 120 and the first boss 310, in some embodiments, the relative positions of the first boss 310 and the light cage 112 are set to have a certain initial amount of compression. That is, the thickness of the portion of the first boss 310 that is deep into the slot 1122 before the optical module 120 is inserted is greater than the thickness of the portion of the first boss 310 that is deep into the slot 1122 after the optical module 120 is inserted.

In another implementation, as shown in fig. 9, the outside of the light cage 112 has a first surface 112b. The heat conductive portion 113 further includes a first heat conductive portion 113b. When the optical module is inserted into the optical cage 112, the first heat conducting portion 113b is pressed, so as to drive the first surface 112b of the optical cage 112 to float. The first heat conducting portion 113b includes a concave structure 410 and a connecting portion 420. It is understood that the first surface 112b may be any surface of the light cage 112.

The concave structures 410 are located on the first surface 112b. When the optical module is inserted into the optical cage 112, the concave structure 410 of the first heat conduction portion 113b contacts the optical module. The concave structure 410 of the first heat conduction portion 113b has a large contact area with the optical module, and can achieve the effect of uniform temperature.

In one implementation, heat can be transferred from the optical module to the concave structure 410 of the first thermally conductive portion 113b by way of direct friction between the concave structure 410 of the first thermally conductive portion 113b and the optical module. In one example, the concave structure 410 has a first groove 411 formed thereon, and the first groove 411 is recessed in a direction approaching the receptacle 1122. The connection part 420 contacts the first bottom surface of the first recess 411, and the connection part 420 extends in a direction away from the socket 1122. In one example, the concave structure 410 and the light cage 112 are a unitary structure. At this time, a portion of the first surface 112b of the optical cage 112 is recessed within the super-receptacle 1122 to form a recessed structure 410 having a first recess 411. In another example, the concave structures 410 may be disposed on the first surface 112b by welding. In yet another example, the concave structures 410 may be floating metal plates disposed on the first surface 112b with a spacing structure, and the concave structures 410 are located within the slots 1122. The limit structure can be a limit pin or a limit column.

It will be appreciated that the concave structure 410 may be a separate piece or may be a unitary structure with the light cage 112.

In order to ensure intimate contact between the light module 120 and the concave structures 410, in some embodiments, the concave structures 410, the light cage 112 are positioned relative to each other with some initial amount of compression.

To better transfer heat away from the concave structures, as shown in fig. 9, in some embodiments, the connection 420 includes a thermally conductive layer 421. The heat conductive layer 421 is in contact with the first bottom surface 411a of the first recess 411.

The heat conductive layer 421 may be made of a material including an interfacial heat conductive material or a metal. The material of the heat conductive layer 421 may have a rebound force, so that the heat conductive layer 421 can make the contact between the concave structure 410 and the optical module more compact, thereby ensuring a heat dissipation effect.

In order to better transfer heat away from the concave structure, as shown in fig. 10, in some embodiments, a second circuit board 140 is disposed between the light cage 112 and the heat spreader 115. The second circuit board 140 is provided with a through hole through which the heat conductive layer 421 passes. In this way, the heat spreader 115 can spread out the heat generated by the second circuit board 140 during operation, and plays a role in dissipating heat from the second circuit board 140.

The cabinet provided in this embodiment of the present application may be provided with the second heat conduction portion 113a shown in fig. 8 alone, or may be provided with the first heat conduction portion 113b shown in fig. 9 alone, or may be provided with the second heat conduction portion 113a shown in fig. 8 and the first heat conduction portion 113b shown in fig. 9 simultaneously as shown in fig. 7. As shown in fig. 7, two different implementations of the heat conducting portion are simultaneously provided, and the second surface 112a and the first surface 112b are opposite surfaces.

In another implementation, the second surface 112a and the first surface 112b are adjacent surfaces of the light cage 112.

In yet another implementation, the second surface 112a and the first surface 112b may also be the same surface, i.e. the heat conducting parts of different implementations may be provided on the same surface.

When the cabinet is provided with the first heat conducting portion 113b as shown in fig. 9 alone, as shown in fig. 11, the heat conducting portion 113 may be provided in plurality, and the plurality of heat conducting portions 113 may be located on different surfaces of the optical cage. For example, the second surface 112a and the first surface 112b are opposing surfaces of the light cage 112.
