COOLANT DISTRIBUTION UNIT FOR A MULTI-NODE CHASSIS

摘要

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.

1. A system, comprising:
a chassis including a plurality of node bays, a coolant distribution unit bay, a coolant supply manifold, and a coolant return manifold, wherein the coolant supply manifold includes a coolant supply outlet in each of the node bays and a coolant supply inlet in the coolant distribution unit bay, and wherein the coolant return manifold includes a coolant return inlet in each of the node bays and a coolant return outlet in the coolant distribution unit bay; a plurality of nodes, each node having an internal heat exchanger, and each node being operatively received into one of the bays with the internal heat exchanger blind connected in fluid communication with one of the coolant supply outlets and one of the coolant return inlets; a coolant distribution unit including an inlet conduit, an outlet conduit, an air-to-coolant heat exchanger in fluid communication between the inlet conduit and the outlet conduit, and a pump for circulating a coolant from the inlet conduit through the air-to-coolant heat exchanger to the outlet conduit, wherein the coolant distribution unit is operatively received in the coolant distribution unit bay with the outlet conduit blind connected in fluid communication with the coolant supply inlet of the coolant supply manifold and with the inlet conduit blind connected in fluid communication the coolant return outlet of the coolant return manifold; and one or more air movers for moving air through the air-to-coolant heat exchanger of the coolant distribution unit.
