A heatsink may include a base and a plurality of fins, configured to be disposed in an air flow, that extend orthogonally from the base. The plurality of fins may have at least one of a height, an inter-fin spacing, or a thickness that varies in a direction of the air flow.

Progressive heatsink

Present thermal solutions to conduct heat from pluggable optical modules into heat sinks use a metal heat sink attached with a spring clip. The interface between the pluggable module and the heat sink is simple metal-on-metal contact, which is inherently a poor thermal interface and limits heat dissipation from the optical module. Heat dissipation from pluggable optical modules is enhanced by the application of thermally conductive fibers, such as an advanced carbon nanotube velvet. The solution improves heat dissipation while preserving the removable nature of the optical modules.
