Radiator of vehicle power module and design method thereof

Abstract

This disclosure provides a design method for a radiator of a vehicle power module. The design method includes: selecting a plurality of specific values from the possible value ranges of the first distance D1, the second distance D2 and the radius R, respectively, to form different combinations of the plurality of specific values, performing simulation calculations on the different combinations, and obtaining a temperature rise ΔTj and a pressure drop ΔPf corresponding to each combination to form a plurality of samples; through a response surface method, fitting explicit functions of the temperature rise ΔTj and the pressure drop ΔPf with the first distance D1, the second distance D2 and the radius R as dependent variables; and through a multi-objective optimization, determining the first distance D1, the second distance D2 and the radius R with an optimization objective that the temperature rise ΔTj and the pressure drop ΔPf are simultaneously minimized.
