酯类油在浸没式冷却系统中的综合性能对比研究
Comparative Study of the Comprehensive Performance of Ester Oil in Immersed Cooling Systems
摘要
Abstract
In the context of the growing demand for effective battery thermal management in electric vehicles,immersed cooling has become as a prominent area of research interest due to its exceptional heat dissipation capability.This study evaluates the physicochemical properties,thermal conductivity,dielectric constants,and material compatibilities of five low-viscosity cooling media including PAO 2,ester oil 1190,silicone oil,CTL 3,and cycloalkyl transformer oil.The findings indicate that the thermal conductivity of all five cooling media diminishes with rising temperature.Notably,the thermal conductivity of ester oil 1190 and CTL 3 is comparatively high,at 0.161 W/m·K and 0.158 W/m·K at 20℃respectively.The ester oil 1190 has excellent thermal stability with the oxidation onset temperature at 226.2℃and the lowest average friction coefficient 0.117.The material compatibility results indicate that ester oil 1190 is compatible with a wide range of plastics such as PEC,PMMA,ABS,and so on,and is less compatible with PS and PVC materials.Furthermore,the flash point(205℃)and ignition point(229℃)of the ester oil 1190 are significantly superior to those of other media,demonstrating its advantages in terms of safety.The study provides crucial data for selection of the immersed cooling media and validates the potential of ester oils to replace conventional media such as silicone oil,mineral oil,PAO,and so on in the immersed cooling systems.关键词
