The Architecture of Advanced Thermal Management
Co-packaged optics drastically reduce signal degradation and power consumption by eliminating long electrical traces altogether. However, this close physical proximity creates extreme thermal bottlenecks that threaten temperature-sensitive optical components.
To solve this, the research team designed two independent heat sinks utilizing manifold microchannel and parallel microchannel arrangements. These distinct channels handle high-flux switch chips and uniform cooling requirements separately to maximize efficiency.
Innovative Microchannel Configurations
The newly developed system incorporates a locally wavy microchannel configuration positioned directly over the primary switch chip hotspot. This specialized geometry significantly enhances heat transfer performance without triggering an excessive pressure penalty.
