Rack-Mounted Immersion Cooling: Servers are submerged in non-conductive dielectric fluid within a rack-sized tank. The fluid absorbs heat, then circulates to a built-in heat exchanger. Specs: Capacity: 50–100kW/rack; fluid temperature: 30–45°C; PUE range: 1. Enterprises are adopting high-performance computing (HPC) for artificial intelligence (AI) and machine learning (ML) model training and inference, causing a fast rise in chip, server, and rack densities, power consumption, and heat levels. Air cooling alone can't abate hot-running equipment. Coolant Distribution Unit (CDU) – Contains the pumping system that circulates the coolant to the cold plates cooling down the CPUs, GPUs, and DIMMs. Liquid cooling leverages the higher thermal transfer properties of water or other fluids to support eficient and cost-efective cooling of k-mounted servers. Supermicro provides total liquid-cooling solutions. Each LiquidRackTM consists of two 12U slide-out drawers, each with its own heat exchanger and pump arrangement. The heated coolant then. Rack manifolds, critical components in liquid cooling solutions, ensure reliable coolant distribution across servers while maintaining modularity and standardization.
