CFD Analysis and Structural Optimization of Water-cooled Intercooler in Automotive Turbocharged Engine Intake System
In a common intake system for a turbocharged automotive engine,the angle between the intake direction of the water-cooled intercooler and the axial direction of the heat dissipation copper tubes of the radiator is close to 90°.In order to avoid thermal stress concentration in the radiator and improve heat dis-sipation efficiency,it is necessary to improve the uniformity of gas distribution inside the heat dissipation copper tubes for high-temperature gases.A method for evaluating the uniformity of gas distribution inside the radiator is proposed,and CFD simulation software is used to analyze the water-cooled intercooler.The structure of the water-cooled intercooler is optimized by adding a baffle in the intake chamber of the in-tercooler.The results show that after structural optimization,the deviation of gas distribution uniformity in-side the radiator of the water-cooled intercooler is reduced from 23％to 4.85％,which improves the heat dissipation performance of the radiator.
