Abstract

A socket assembly (104) includes a heat sink assembly (200) for a socket cage (110) for dissipating heat from pluggable modules (106) inserted into the socket cage. The heat sink assembly includes fin plates (202) and spacer plates (204) arranged in a stack (206) of plates that can be independently moved to engage and conform to the pluggable modules. Each spacer plate includes a thermal interface (228) at a bottom (222) of the spacer plate to engage the pluggable modules. Each fin plate includes a thermal interface (248) at a bottom (242) of the fin plate to engage the pluggable modules. The fin plates include unbranched fin plates (250) and branched fin plates (260). Each unbranched fin plate is planar between the bottom and a distal end thereof. Each branched fin plate is non-planar between the bottom and the distal end thereof and includes at least one bend (262).
