摘要
温度循环试验箱由于试验条件的严苛,容易存在温度均匀性不好的现象。为了改善温度循环试验箱的测试区域的温度均匀性,本研究采用先进的CFD(Computational Fluid Dynamics)数值模拟技术,结合现代流体力学和传热学理论,建立了试验箱内部温度场的数学模型,并通过对比分析实测数据与模拟结果,揭示了当前设备在温度均匀性方面存在的不足,并提出了改变箱体结构的优化设计方案。实验结果显示,经过优化后的温度循环试验箱,其在测试区域的对流换热更加充分,内部温度场的均匀性得到了显著提升,有效地减少了温度分布的不均匀性,使得各点间的温度差异大幅降低。本文的研究,提高了试验数据的可靠性和精确度,确保了试验结果更好地反映被测样品的真实性能,同时也增强了试验箱整体工作效率和测试质量。
The temperature cycling test chamber is prone to poor temperature uniformity due to the harsh test conditions.In order to improve the temperature uniformity of the testing area in the temperature cycling test chamber,this study adopted advanced CFD(Computational Fluid Dynamics)numerical simulation technology,combined with modern fluid mechanics and heat transfer theory,to establish a mathematical model of the internal temperature field of the test chamber.By comparing and analyzing the measured data and simulation results,the shortcomings of the current equipment in temperature uniformity were revealed,and an optimized design scheme for changing the structure of the chamber was proposed.The experimental results show that the optimized temperature cycling test box has more sufficient convective heat transfer in the testing area,significantly improving the uniformity of the internal temperature field,effectively reducing the non-uniformity of temperature distribution,and significantly reducing the temperature difference between different points.The reliability and accuracy of experimental data have been improved,ensuring that the test results better reflect the true performance of the tested sample,while also enhancing the overall efficiency and testing quality of the test chamber.
