What Is Thermal Imaging Survey?_
A thermal imaging survey is a diagnostic procedure performed with an infrared camera to identify hot spots, uneven heat distribution, or cooling failures in data center equipment. It is typically conducted under load to reveal issues like loose connections, failing components, or blocked airflow that might not be visible otherwise. The survey provides a visual heat map that guides corrective actions before full production deployment.
Technical Details
The survey targets high-current connections (e.g., busbars, power distribution units) and liquid cooling loops (e.g., cold plates, quick disconnects) where thermal gradients indicate resistance or flow issues. Infrared cameras with high thermal sensitivity are used; exact specifications follow the OEM or commissioning standard. Surveys are performed at steady-state load, typically after 30–60 minutes of operation, to allow thermal stabilization. Results are documented with time-stamped images and compared against baseline thresholds defined by the equipment manufacturer.
How Leviathan Systems Works with Thermal Imaging Survey
During Leviathan Systems commissioning, field crews run thermal imaging on GPU racks after power-on and liquid cooling loop verification, focusing on NVLink spine cables and cold plate interfaces. Any anomaly triggers immediate corrective action per OEM procedures (e.g., reseating connections or re-torquing bolted interfaces) before network cabling is finalized.
