[0001] The utility model relates to the technical field of optical communication modules, in particular to a liquid-cooling and heat-dissipating optical module. Background Art
[0002] In the field of optical communications, traditional optical modules typically use air cooling, whereby the module dissipates heat through top-mounted heat sinks. However, as optical module power consumption increases, especially for high-power modules like 1.6T or coherent modules, the heat dissipation capacity of this air cooling method has reached its limit (the maximum heat dissipation capacity of optical modules using top-mounted heat sinks is approximately 20W), and it cannot meet heat dissipation requirements above 30W. Therefore, it is necessary to develop a new heat dissipation method to improve the heat dissipation efficiency of optical modules. Utility Model Content

In addition, after adopting the above structure, it has the advantage of convenient connection between the joint and the heat conductor.
