A pluggable module includes a housing having a top wall including an opening above a module cavity. The pluggable module includes a heat exchange assembly separate and discrete from the housing extending into the module cavity through the opening. The heat exchange assembly includes a thermal bridge having an upper thermal interface and a lower thermal interface. The thermal bridge includes a plurality of interleaved plates arranged in a plate stack with the plates being movable relative to each other in the plate stack. The lower thermal interface is in thermal communication with the electrical component to dissipate heat from the electrical component. The thermal bridge extends through the opening with the upper thermal interface exposed from above for dissipating heat from the heat exchange assembly.
