Abstract
A system includes a chassis, a plurality of nodes, a coolant distribution unit (CDU), and one or more air movers. The chassis includes multiple node bays, a CDU bay, a coolant supply manifold with an inlet in the CDU bay and an outlet in each node bay, and a coolant return manifold an inlet in each node bay and an outlet in the CDU bay. Each node is received into a node bay with an internal heat exchanger connected between a coolant supply and return manifolds. The CDU is received in the CDU bay and includes an air-to-coolant heat exchanger in fluid communication between the supply and return manifolds, and a pump for circulating a coolant through a coolant loop. The one or more air movers force air across the air-to-coolant heat exchanger of the CDU.
