Abstract：Tube-belt radiator is one of the indispensable parts in the cooling system of crushing machinery. By improving the radiator of the crusher, the reasonable matching of the heat dissipation and power of the radiator can ensure the stable and safe operation of the crusher, improve the reliability of the work, and prolong the service life of the crusher. The mathematical model and geometric model of fluid dynamics were established. According to the mathematical model, the mesh division and boundary condition setting were carried out. The temperature field simulation analysis of the radiator was carried out by Fluent software. The results show that for the fins of the tube-band radiator, increasing the vibration speed can significantly improve the heat transfer effect, and it will weaken the heat transfer when the wind speed is greater than 5 m/s. Using the oscillation effect can enhance the heat transfer effect of the tube-band radiator and improve the performance of the radiator.
