Standards Development
This document specifies the test method for determining the adaptability of materials, components or equipment in an immersion coolant environment.
This test method aims to verify the mutual influence between coolants and products, and guide the selection, use, maintenance, and testing for materials, components or equipment.
This test method is applicable to both the single -phase immersion cooling condition and the phase -change immersion cooling condition. The corresponding test method should be selected based on the cooling conditions of the product during the test.
Immersion cooling exposes electrical and electronic (EE) components/equipment to concurrent effects (liquid absorption, dissolution/precipitation of soluble material constituents, chemical reactions), with material mass/volume changes as the primary manifestation. Coolants themselves degrade under prolonged exposure to air and EE components, evidenced by altered molecular structure, acid value, and fluoride ion concentration.
A key unresolved question is whether prolonged coolant immersion causes compatibility issues or failures in EE products. While immersion coolants’ superior heat-carrying capacity reduces spatiotemporal temperature fluctuations compared to air cooling, they introduce unique lifecycle stresses absent in traditional air -cooled systems—stresses driving material performance degradation and component functional failure via mechanical, chemical, electrical, and thermal mechanisms.
This research addresses the long-term operational reliability of EE materials, components, and finished products in immersion cooling environments. Its core objective is to establish standardized test methods for EE products under such conditions, providing theoretical and experimental foundations for practical engineering applications in line with IEC standardization requirements
