Abstract: The systems and cold plate pedestal and assembly described decrease mechanical stresses in integrated circuits, while also providing efficient thermal coupling between heat producing components and a cold plate. A cold plate assembly includes a cold plate with a pedestal portion a groove formed in a surface of the pedestal portion. The cold plate assembly also includes a thermal pad layer formed in the groove and a phase change material (PCM) layer formed on the surface of the pedestal portion and a surface of the thermal pad layer formed in the groove.

Abstract: Aspects described herein include an apparatus comprising a receptacle comprising a cage dimensioned to receive a pluggable optical module into an interior volume, An opening is defined in an exterior surface of the cage. The apparatus further comprises a heat sink assembly rigidly attached to the cage. The heat sink assembly comprises a thermal interface material extending through the opening into the interior volume. The thermal interface material is configured to compress when the pluggable optical module is received into the interior volume and contacts the thermal interface material.

Abstract: An apparatus includes a heat pipe, a first fin, and a second fin. The heat pipe includes a first end and a second end. The heat pipe defines a chamber through which a fluid flows. The first fin is coupled to the heat pipe at the first end. The first fin is arranged to absorb heat from the fluid at the first end such that the fluid at the first end flows back towards the second end. The second fin is coupled to the heat pipe between the first fin and the second end. The second fin is arranged to absorb heat from the fluid as the fluid flows from the second end towards the first end.

Abstract: Embodiments for providing cooling airflow through electronic in two different directions is described. An airflow control louver system in an electronic device provides for cooling airflow to be efficiently routed through the electronic device in the two different directions which in turn allows for multiple installation configurations for electronic devices with high powered heat sensitive components.
