Liquid Cooling Solution
Cold plate liquid cooling and CDU systems for high-density thermal management.
The Problem
Customer Challenge
As rack power density rises with AI and HPC workloads, air cooling alone can no longer remove heat efficiently or cost-effectively, risking thermal throttling and reliability issues.
The Approach
Solution Architecture
Wandtung's liquid cooling solution applies cold plate direct-to-chip cooling at the server level, with a CDU isolating and managing the primary (facility) and secondary (rack) coolant loops, including leak detection and monitoring.
System
System Components
Cold Plates
Direct-to-chip liquid cooling at the server/GPU level.
CDU
Manages primary/secondary loop separation, flow and temperature.
Leak Detection & Monitoring
Sensor-based leak detection and real-time system monitoring.
Architecture
How It Works
- 1
Cold plates absorb heat directly from CPUs/GPUs into the secondary coolant loop.
- 2
The CDU exchanges heat between the secondary (rack) loop and the primary (facility) loop.
- 3
Facility cooling infrastructure rejects heat from the primary loop.
- 4
Leak sensors and flow/temperature monitoring protect IT hardware continuously.
