Abstract
An integrated heatsink for a co-packaged optical-electrical module includes a base plate attached on top of a co-packaged optical-electrical module. The integrated heatsink further includes a plurality of fin structures extended upward from the base plate except a central cavity region with missing sections of fins, each fin extended along an axial direction from a front edge to a back edge of the base plate except some trenches shallow in depth across some fin structures and some other trenches deep in depth down to the base plate either along or across some fin structures. Additionally, the integrated heatsink includes multiple heat pipes including shaped portions embedded in the trenches in the plurality of fin structures. At least one bottom horizontal portion per heat pipe is brazed to the base plate in a corresponding region that is superimposed on hot spots of the co-packaged optical-electrical module under the base plate.
