Study on Improving Condensing Capacity of 30B Container

Aiming at the insufficient condensation capacity of the 30B vessel in the late stage of receiving in the current uranium enrichment plant，a copper triangular heat dissipation rib was designed，and the heat dissipation performance of the 30B vessel in the cold air box was simulated based on Flow simulation，and the heat dissipation rib was optimized. The results show that the best heat dissipation effect is achieved when the forced air cooling wind direction and the impact angle of the cylindrical container are 180°，and the container condensation efficiency is increased by 14.5% on average at 263.15 K，wind speed of 3 m/s，calculation length of 2400 s，and 70 cooling ribs compared with that when there is no loading of cooling ribs，and the average cooling efficiency is improved by 14.9% after optimizing the design of cooling ribs，and the cooling efficiency is increased by 19.9%，and at 248.15 K，with a wind speed of 3 m/s，the average thermal efficiency is improved by 30.4%. It proves that the 30B container can improve the thermal efficiency of the container after loading the external copper heat sink，which lays the foundation for the subsequent popularization of 30B direct charging.
