This paper presents a hybrid modeling method of finite element method(FEM)and computational fluid dynamics(CFD).The response surface was generated by single factor experiment,and the single factor and interactive effects of nozzle di-ameter,angle and pressure on the maximum temperature of the tool were analyzed.The orthogonal experimental design method is adopted to study the influence of the above four factors on the tool cooling through simulation analysis,with the maximum tem-perature of the tool as the evaluation index and the section shape,width,depth and distribution angle of the microchannel as the influencing factors.The results show that the rectangular microchannel with larger cross-section width has better cooling effect,the angle and depth of microchannel take the second place,and the shape of microchannel has the least effect.Through the verifi-cation of the model,the validity of the model is proved.
