| 随着电子器件的散热需要越来越大，关于液体冷却系统的研究愈发增多。瞬态喷雾冷却(ISC)是其中一个新颖高效的冷却IC芯片的方法。本文使用导热逆问题(IHCP)来计算喷雾冷却过程中随时间变化的表面热流。IHCP是一种通过测量介质内部的温度分布来估计表面热通量的计算方法。本文选用一维未来时间步长序列函数方法(SFS)方法由测量内部温度而估计表面热流。使用模拟温度数据来检查该计算方法的精度和误差，得到各个参数影响的规律以估计该方法对实验中求解的热流密度的影响。 |

| With the increasing heat dissipation of electronic devices, the research on liquid cooling system is increasing. Intermittent spray cooling (ISC) is a novel and efficient method for cooling IC chips. We use the inverse heat conduction problem (IHCP) to predict the time-varying surface heat flow during the spray cooling process. IHCP is a method for estimating surface heat flux by measuring the temperature distribution inside the medium. In this paper, the one-dimensional sequential function specification method (SFSM) is used to estimate the surface heat flux by measuring the internal temperature. The accuracy and error of the calculation method are checked by the simulated temperature, and the rule of the influence of each parameter is obtained to estimate the effect of the method on the heat flux calculated in the experiment. |
