LUVE said it is developing solutions for immersion-cooling architectures in data centers and has worked with Castrol to validate the compatibility of LUVE’s copper brazing joints with Castrol’s dielectric fluids. The testing was aimed at assessing long-term material stability, fluid integrity and safe system operation.
Castrol evaluated five brazing types with DC15, DC15 with corrosion inhibitor and DC20 dielectric fluids. The tests ran for 336 hours at 80°C (176°F) in a forced-draft oven, using 310 ml (about 10.5 fl oz) of fluid per sample. Before testing, the samples were cleaned to remove residues and oxide layers.
According to LUVE, visual inspection showed no significant changes across the tested copper-brazing types after immersion in DC15 or DC20. The company said infrared spectrum analysis indicated stable fluid chemistry, electrical conductivity showed only insignificant increases, and particulate-count values remained below upper limits.
In its final summary, Castrol said: “Neither Castrol ON Immersion Cooling fluids nor copper brazing samples showed a significant change after combined accelerated aging.” Castrol also recommended flushing the system before first fill to support long-term fluid performance.
