AI Overview
Computing server water chillers are
specialized cooling systems designed to remove high-density heat from IT equipment, utilizing water's superior thermal conductivity to maintain optimal operating temperatures, especially for AI and high-performance computing (HPC) workloads. These systems, which can be part of large-scale facility infrastructure or compact "in-row" units, often achieve better energy efficiency (lower PUE) than traditional air-cooled methods, according to Lenovo and Supermicro.Types of Server Water Chillers & Cooling Systems
- Chilled Water Systems (CRAH): Computer Room Air Handlers (CRAHs) use a central chiller to provide cold water to air handlers, which then cool the room air.
- In-Row Chilled Water Cooling: Close-coupled units, such as APC InRow, are placed directly between server racks to capture hot exhaust air and provide efficient, localized cooling.
- Direct-to-Chip (DLC) Liquid Cooling: Cold plates are attached directly to high-heat components like CPUs and GPUs, with water circulating to remove heat before it enters the air, reducing cooling energy by up to 40%.
- Rear Door Heat Exchangers (RDHx): A liquid-cooled heat exchanger is installed on the rear of the server rack, capturing heat from the hot exhaust air.
- Immersion Cooling: Servers are submerged in a thermally conductive, non-conductive dielectric fluid, allowing for massive heat reduction.
Key Components and Features
- Coolant Distribution Units (CDUs): These provide temperature and flow rate control for the secondary cooling loop, often using a liquid-to-liquid heat exchanger to move heat from the racks to the facility water loop.
- Leak Detection & Monitoring: Advanced systems include sensors to notify users of potential water leaks within the cooling unit.
- Titanium Heat Exchangers: Used in high-quality, corrosion-resistant chillers (e.g., Hailea).
- Variable Speed Fans/Pumps: These optimize power usage by adjusting to the cooling load.
Benefits of Water Cooling
- Improved Efficiency: Liquid-cooled systems can reduce power costs by up to 40% compared to traditional air cooling.
- Higher Density: Enables higher rack densities (over 20 kW), which is necessary for AI hardware that can exceed 1,200 watts per GPU.
- Performance Stability: Prevents thermal throttling in CPUs and GPUs.
- Sustainability: Allows higher water temperatures, reducing the need for mechanical refrigeration ("free cooling").
Key Manufacturers and Solutions
- APC by Schneider Electric: InRow Chilled Water Cooling.
- Vertiv: Liebert® AFC high-capacity inverter screw chiller.
- CoolIT Systems: Direct Liquid Cooling (DLC) for HPC and AI.
- Boyd: High-capacity, customizable liquid cooling systems.
- S&A Teyu: Industrial water chillers (e.g., CW-7800).
- Submer: Immersion cooling technology.
These systems are increasingly necessary as AI chip power reaches 1,200 watts, with some projections going up to 5,000 watts, making traditional air cooling incapable of handling the heat.
