中文摘要:
      目的 探讨蓄冷剂摆放位置不同时,保温箱保温过程中内部温度场的分布情况和变化规律。方法 应用有限元法,以ICEMCFD建立保温箱基本模型,并通过改变模型内部蓄冷剂的摆放位置建立侧面摆放(2种)、顶部摆放和边缘摆放共4种摆放方式。将内部空气的对流换热与箱体的热传导过程统一成一个整体,通过Fluent进行热流耦合分析。结果 得到了保温箱内部温度场分布一般规律,蓄冷剂摆放位置不同时温度场分布情况有很大差异,其中边缘摆差异性最大,侧摆次之,顶摆温度场分布最均匀。结论 针对可利用体积、温度场均匀程度、箱内平均温度来说,顶摆方式无疑是最佳的蓄冷剂摆放位置。
英文摘要:
      The work aims to study the distribution and change law of the temperature field inside the incubator during its thermal insulation when the ctesms is placed at different positions. The fundamental model of incubator was established in the finite element method by ICEMCFD, and four kinds of layouts were built by changing the placement of the ctesms inside the model, including the side placement (two kinds), top placement and edge placement. The convective heat transfer of internal air and heat conduction of box were unified as a whole to carry out the thermal-fluid coupling analysis by Fluent. The general rule of temperature field distribution inside the incubator was obtained. With the different positions of the ctesms, temperature field distribution was very different when the edge placement was of the biggest difference, followed by the side placement. The temperature field of top placement was distributed the most uniformly. In terms of available volume, temperature field uniformity and average temperature inside the incubator, it is no doubt that the top placement is the best choice for the ctesms.
