1/3 the size of the previous generation, with 252 pairs installed
per system.
Application Fields
AI Data Centers: GB300 NVL72 rack-scale AI servers (supporting
large language model inference / training);
Supercomputing / High-Performance Computing (HPC): Large-scale
parallel computing tasks (e.g., scientific simulation, quantum
computing assistance);
High-Density Computing Scenarios: Modular computing units such as
Meta Clemente 1U 4-GPU compute sleds.
Cold Plate Radiator
According to the power consumption data and power consumption
distribution location of the cold plate heat dissipation provided
by the customer, we design the internal flow channel of the cold
plate in a targeted manner.
Flow channel design objectives:
The surface temperature of the cold plate meets the customer's
requirements for temperature rise and temperature uniformity
performance;
The fluid flow resistance inside the cold plate is within the
allowable range.
Perform simulation analysis on temperature and pressure drop for
the designed flow channels, and adjust the design values of
different internal parameters of the cold plate according to the
analysis results until both the temperature and pressure drop
requirements are met simultaneously.
