摘　　要：针对高温真空炉壁的水冷水道选型设计困难,而传统水道设计方法依赖经验的现状,提出了一套适用于真空炉壁水冷水道的设计方法。在带反射屏炉衬的辐射传热环境下,该方法首先用玻尔兹曼定律计算通过反射屏损失的热流量;其次利用比例法计算反射屏炉衬边缘损失的热流量,即可得到真空炉体损失的热流量;再次通过比热容公式计算冷却水的体积流量与水管当量直径;最后通过仿真实验对设计的真空炉体进行验证。结果表明,设计的真空炉体在辐射传热中的炉体内壁温度小于310 K,基本上与计算结果一致。该方法计算的结果与仿真实验结果具有较高的一致性,可满足类似真空炉体水冷水道散热系统的设计。In response to the dfficulty in selecting and designing water-cooled water channels for high-temperature vacuum furnace walls,and the current situation where traditional water channel design methods rely on experience,a design method suitable for water-cooled water channels for vacuum furnace walls is proposed.In the radiation heat transfer environment with a reflective screen lining,this method first calculates the heat loss through the reflective screen using Boltzmann's law;Secondly,the heat flux loss at the edge of the reflective screen lining can be calculated using the light ratio method to obtain the heat flux loss of the vacuum furnace body;Calculate the volumetric flow rate of cooling water and the equivalent diameter of the water pipe again using the specific heat capacity formula;Finally,the designed vacuum furnace body was verified through simulation experiments.The results indicate that the wall temperature of the designed vacum furnace in radiative heat transfer is less than 37 C,which is basically consistent with the calculated results.The results calculated by this method have a high consistency with the simulation experimental results,which can meet the design of cooling systems similar to vacuum furnace water-cooled water channels.
