A cooling apparatus for a pluggable module comprises a pluggable module cage to house the pluggable module and a heat pipe coupled with a hot interface at one end and a cold interface at another end. The cooling apparatus further comprises an attachment mechanism for attaching the hot interface and the heat pipe to the pluggable module. The attachment mechanism permits mobility required to insert and secure the pluggable module in place inside the pluggable module cage to allow a good thermal coupling between the hot interface and the pluggable module.
