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: A micro liquid cooling device including a radiator, a thermal conductor, an actuator, and a circular path is proposed. The actuator includes a cavity sealed with a thin film, an inlet diffusion port connected to the cavity, an outlet diffusion port connected to the cavity, a magnetic body connected to the thin film, and a pole acting on the magnetic body, such that circulation of a liquid coolant in the circular path can be effected. By such design of the actuator, vibration and noise can be reduced and reliability can be improved, and thus problems caused by the use of a prior-art technique which employs a piezoelectric pump as an actuation source for the liquid coolant can be solved.
