【摘要】：为提高高温熔盐泵散热器的散热效果,对影响散热器散热面积的重要因素——散热孔的直径和数量进行了数值优化,并将数值模拟得到的热载荷加载到结构体上,分析了热载荷下的热变形。结果表明:散热孔直径为12 mm、散热孔数量为6时,散热流体的流动均匀稳定,泵轴和散热器的综合散热效果较好,最终泵轴顶端的平均温度可降到440 K,散热器顶端的平均温度可降到417.5 K,满足散热需求;泵轴热变形量较小,最大值为0.46 mm,散热器的变形量较大,最大值为2.37 mm,加工时必须考虑材料的热膨胀和热变形。
[Abstract]:In order to improve the radiating effect of high temperature molten salt pump radiator, the diameter and number of cooling holes, which are important factors affecting the radiator area, are numerically optimized, and the thermal load obtained by numerical simulation is loaded on the structure. The thermal deformation under thermal load is analyzed. The results show that when the diameter of the cooling hole is 12 mm, and the number of the cooling holes is 6, the flow of heat dissipation fluid is uniform and stable, the comprehensive heat dissipation effect of the pump shaft and radiator is better, and the average temperature at the top of the pump shaft can be reduced to 440K. The average temperature at the top of the radiator can be reduced to 417.5 K to meet the demand for heat dissipation. The heat deformation of pump shaft is small and the maximum value is 0. 46 mm, radiator. The thermal expansion and deformation of material must be considered when the maximum value is 2. 37 mm,.
