Description
Technical Field
The invention relates to the technical field of optical communication, in particular to a shell assembly of an optical module, the optical module and communication equipment.
Background
The QSFP-DD optical module structure is developed based on a QSFP optical module, the QSFP-DD optical module structure is slightly longer than the QSFP optical module in appearance, but the number of optical channels is doubled, namely the number of photoelectric devices is doubled, and due to the application of the PAM4 technology, the number of relevant electric chips and electric devices used by the QSFP-DD optical module is greatly increased, so that the internal heat productivity of the QSFP-DD optical module is greatly increased, but the area of external heat dissipation is increased very little. On the other hand, all heating devices in the module transmit heat to the optical module structural shell firstly, and then the shell dissipates the heat. In actual use of the optical module, the bottom surface of the optical module is tightly attached to other components, so that the heat dissipation air channel 22 is blocked, and the direct heat dissipation to the outside through the bottom surface shell cannot be realized. The heat transferred to the bottom shell needs to be transferred to the top shell to be effectively dissipated. This results in a lengthy heat transfer path and a thermal bottleneck at the top and bottom case interfaces. Therefore, the QSFP-DD optical module has large heat productivity and difficult heat dissipation, and is very easy to cause overhigh module temperature and serious performance degradation. The common solution is to add a refrigeration component inside the module to maintain the temperature of the temperature sensitive device within a small working temperature fluctuation range, thereby ensuring the normal operation of the optical module.
In the practical application of QSFP-DD optical module products, how to solve the problems of module heating and heat dissipation becomes a key point to be solved urgently. According to the scheme of adding the refrigeration part, on one hand, the cost and the structural complexity of the optical module are increased due to the addition of the refrigeration part, and on the other hand, the overall power consumption of the optical module is greatly increased due to the fact that the power consumption of the refrigeration part is large. In the development of the existing optical fiber communication industry, customers all require that the optical module has higher speed, smaller volume and power consumption and more economical and practical price. The aforementioned cooling solutions are not feasible given the severe constraints on the power consumption and cost of the optical module. Particularly, the currently prevailing COB structure optical module pursues the structure to be extremely simple, and does not consider a refrigeration device at all. Under the contradiction that the optical module has large heat productivity and poor heat dissipation, the performance index of the optical module is forced to be reduced, and the use condition is also limited.

In the specific example of the present invention, the heat dissipating protrusions 21 are integrally formed on the case 1, but it is not excluded that a plurality of heat dissipating protrusions 21 are formed on one integral structural member that can be assembled on the case 1.
The optical module of the invention can not only utilize the heat dissipation bulge 21 to enhance heat dissipation, but also utilize the heat dissipation air channel 22 to enable forced airflow to flow when proper forced airflow is provided in the use environment, and the passing of the airflow is beneficial to taking away heat, thereby further enhancing the heat dissipation capability of the optical module.
