AB - The shell-and-tube heat exchanger is an important equipment in various  applications. However, the bundle vibration and low heat transfer  efficiency are the main shortcomings. In this article, ANSYS platform was  used to simulate and analyze the shell-and-tube heat exchanger, the natural  frequency was calculated, and the dominant factors affecting the vibration  were determined. The theory of inventive problem solving was used to design  the heat exchanger for anti-vibration. The results show that the improved  heat exchanger's natural frequency is much larger than the fluid excitation  frequency, as a result, the resonance is avoided.
