Abstract: A processing unit disposed within a compute unit, where the compute unit includes a printed circuit board (PCB) that includes an integrated circuit; a first thermal management device, that includes a first vapor chamber thermally conductively coupled to a first side of the integrated circuit; and a first heatsink thermally conductively coupled to the first vapor chamber; and a second thermal management device, that includes a second vapor chamber; and a second heatsink thermally conductively coupled to the second vapor chamber, where the second thermal management device is thermally conductively coupled to the first thermal management device; where the PCB is interposed between the first thermal management device and the second thermal management device.

Abstract: A passive hybrid heat transfer system for cooling a heat source, such as an integrated circuit, includes a thermosiphon heat transfer subsystem that operates in combination with a supplemental heat transfer subsystem to transfer heat away from and thereby cool the integrated circuit. The heat transfer system includes the thermosiphon heat transfer subsystem including a condenser coupled to an evaporator. The evaporator is coupled to the integrated circuit or other heat source and is positioned below the condenser relative to a direction of gravity. The supplemental heat transfer subsystem is thermally coupled to the evaporator of the thermosiphon heat transfer subsystem and has at least a portion extending below the evaporator relative to the direction of gravity. A network device like a switch or router may include the hybrid heat transfer system to cool high power integrated circuits without the need to resort to active cooling systems.

Abstract: A processing unit. The processing unit includes a printed circuit board (PCB) including a lidless integrated circuit, a heatsink, and a damper system. The heatsink is coupled to the PCB and in thermal communication with the lidless integrated circuit via a thermal interface material. The damper system is compressed between the PCB and the heatsink and surrounding the lidless integrated circuit to absorb a portion of kinetic energy imparted to the lidless integrated circuit by an impact to the processing unit.

Abstract: A mechanism to mitigate assembly torsion on an electronics assembly is provided. The mechanism including an electronics assembly and a first connector, mounted to the electronics assembly with a lower portion of the first connector proximal to the electronics assembly and an upper portion of the first connector distal to the electronics assembly. The mechanism includes a spring, mounted so as to press the upper portion of the first connector and preload the first connector against assembly force imparted by assembly of the first connector to a second connector. A method to mitigate assembly torsion on an electronics assembly is also provided.
