Compute Tray: Thermal - Line hint:

Context Before
The coolant enters the compute tray via UQD from the left rear side of the chassis. Then, the coolant enters the internal manifold via a tube, where the coolant is distributed to all the modules. The coolant collects the heat from the different modules and re-enters the internal manifold.
Evidence
Finally, the coolant exits the compute tray via UQD at the rear right side of the chassis.
Context After
Several upgrades are also made on the cold plate for VR NVL72. For each Strata module, the cold plate will be provided as a single module covering the entire Strata board including two Rubin GPUs, one Vera CPU, SOCAMM modules, and the various VRM components. The cold plate of the Rubin GPU is upgraded to a “micro-channel cold plate” (MCCP). Essentially, the pitch between the channels in the cold plate is reduced to 100 micron from 150 micron.
② Atomic Claim
最後 coolant 從 chassis 右後側透過 UQD 離開 compute tray。
