Liquid Cool
ICM-21 Interactive 3D Model
2U, 21-inch intra-chassis manifold. Brazed stainless body, five hard-wired branches, 100% pressure and helium leak tested.
About the ICM-21
ICM-21 sits inside the 21-inch, 2U liquid-cooled tray, between the chassis quick disconnects and the cold plates. A CNC-machined and brazed stainless body splits inhibited PG25 across five hard-wired branches: the centre pair feeds the ASIC and VRM cold plates, and the four outer pairs feed OSFP. The split is fixed by the internal geometry, not by valves, so there is nothing to set or drift in the field.
The cold and hot rows are isolated chambers with no cross-flow. Dry-break quick disconnects sit on the face, and options 3 and 4 add chassis BMQCs with fitted hoses, so the manifold drops into the tray as a finished assembly.
Every unit is hydrostatically proof-tested and helium leak-tested, cleaned and dried for PG25 service, and shipped capped with a serialised test record.
