Title: Cooling device for pluggable module, assembly of the cooling device and the pluggable module

Abstract: Provides a cooling device (100) for cooling at least one pluggable module (200) each having a pluggable component (20) and a frame (32) for accommodating the pluggable component, the frame having an opening (33) on a top wall thereof. The cooling device comprises at least one thermal conductive block (40), a heat radiator (70) and a resilient thermal conductive pad (60). The resilient thermal conductive pad being adapted to be in a substantially released position when the pluggable component is decoupled from the frame and substantially biased when the pluggable component is inserted into the frame thus exerting a biasing force on the thermal conductive block and the heat radiator whereby the thermal conductive block is pressed through the opening of the frame into direct thermal contact with the pluggable element of the pluggable module for conducting the heat generated by the pluggable component to the heat radiator through the thermal conductive block and the resilient thermal conductive pad. The main advantage of the cooling device is that the pluggable module has a reinforced and compact cooling structure that improves the heat dissipation efficiency.
