    摘要: The front of a rack-mounted 2 RU (Rack Unit) chassis includes bays that receive replaceable components, such as storage drives. Two rear slots of such chassis each receive hot-swappable 1 RU servers that couple to a midplane of the chassis. When a server is removed from its slot while the server in the other slot remains operational, the airflow output of the operational server escapes via the empty slot rather than cooling the components in the front-facing bays. Embodiments provide a single-blade air damper that blocks airflow via an empty chassis slot. The single-blade air damper is connected to spring assemblies on both chassis sidewalls. The spring assemblies are maintained in unstable states when servers are installed in both slots of the chassis. Upon a server being removed from a slot, the spring assemblies transition to stable states that position the single-blade air damper to block airflow via the empty slot.

    摘要: An information handling system includes two or more heat-generating devices and a liquid-assisted air cooling (LAAC) assembly to cool at least some of the devices. The LAAC assembly includes a radiator, first and second pumps connected in series with the radiator. The LAAC assembly further includes first and second cold plates enclosing first and second CPUs or another suitable heat generating device. The first and second cold plates are connected in parallel between an inlet of the first pump and an outlet of the second pump. In this configuration, the serial connected pumps in combination with the parallel connected cold plates provide 1+1 pump redundancy while delivering cold coolant from the radiator outlet to both heat generating devices such that neither heat cold plate receives pre-heated coolant from the other cold plate.
