src=With the rapid development of communication equipment, the integration and assembly density of communication equipment have been improved, and the power consumption and heating capacity have increased dramatically while providing powerful use of the function. In all components, the temperature specification of optical module is relatively low, usually the commercial optical module shell temperature is limited to 65~70, the space is tightened, the pluggable requirements, and the low temperature specifications are the challenges of the optical module heat dissipation, and even become the bottleneck of the entire product development.
 
The traditional thermal solution is using natural convection heat dissipation, the way is fix a heat sink on the top of optical module cage, the top of the cage has a window, the heat sink is in direct contact with the optical module, heat radiates through the heat sink to the natural environment, this is currently passive cooling solution. But this way has become increasingly unable to meet the rapid development of the communications industry, the launch of 5G put forward higher requirements on the optical module, the active cooling system becomes more and more important and urgent.
