To solve the resonance problem of the thermal management integrated module assembly after the installation of the motor, based on modal solution theory of elastic mechanics, a 3D model of the assembly was established, utilizing the motor acceleration test data as the excitation, and the response parameters under multimodal modes were obtained by Finite Element Analysis (FEA). The analysis discovers that there is a risk of resonance between module assembly and single pump at low frequencies, corresponding to the 5th, the 8th order models of module assembly and the 4th, the 10th order models of single pump respectively. The resonance region is concentrated around 1 310 Hz and 1 900 Hz at high frequencies. Based on the above analysis, the centroid position of the module assembly and the inner wall structure of the pump volute were optimized and verified experimentally, the research shows that the sound pressure level of the optimized assembly structure is reduced by 7.2 dB(A), 0.2 dB(A), 2.3 dB(A), 7.1 dB(A), 2.3 dB(A) in the X+, X-, Y+,Y- and Z+ directions respectively. Compared with the noise test data, the discrepancy is less than 5%, and the resonance is suppressed effectively.
