Numerical Analysis of Fluid-thermosolid Coupling of Plate-fin Oil Cooler for New Energy Vehicles
This paper takes a mass production zigzag staggered fin oil cooler as the research object.Through calculation and CFD simulation,the pressure drop value and heat dissipation value of the oil side and water side under three working conditions are obtained.Combined with the heat fluid-solid coupling simulation,the temperature change,thermal stress and thermal deformation of the oil cooler are ana-lyzed.Moreover,the maximum strain in the vertical direction is 0.043 mm,accounting for 1.9% of the total deformation,indicating that the strain and deformation of the oil cooler will not have a greater im-pact,which provides data support for the selection and design of the car oil cooler.
