Abstract：

For the problem of flow distribution uniformity for complex parallel pipeline cooling system in the thermoforming die, the cooling system model in the thermoforming die of front anti-collision beam for a certain car was established, and the numerical simulation analysis on the flow distribution of the cooling system was conducted by software STAR-CCM+. Then, the influences of pipe length and inlet flow on the flow distribution in the cooling system were studied, which was verified by the flow field state detection platform of die cooling system. The results show that the results of the simulation in the flow distribution were consistent with the experimental results. The pipe flow distribution is greatly affected by pipe length and inlet flow. The greater the difference in the pipe length is, the worse the uniformity of flow distribution in the cooling system is. As the inlet flow increases, the flow distribution uniformity of flow field becomes worse. Compared with the simulation results, the detection platform reflects the distribution of the flow field better. In addition, the maximum inlet flow of the cooling system can be measured by the detection platform, and the maximum inlet flow value of the cooling system in the die of front anti-collision beam is about 19 m3·h-1.
