摘要
采用9点分布式热电偶实时测量烤箱每层温度场分布,测定分析烤箱温度均匀性,并运用计算流体力学对烤箱内部温度场进行数值模拟。结果表明,通过优化烤箱后挡板结构,调节风量分配,改变出风孔布局等方案显著地提升了烤箱内部温度场的均匀性。
A 9-point distributed thermocouple was used to measure the temperature field distribution of each layer of the oven in real time,and the oven temperature uniformity was determined and analyzed.Moreover,the internal temperature field of the oven was numerically simulated using computational fluid mechanics knowledge.The results showed that the uniformity of the temperature field inside the oven was significantly improved,by optimizing the structure of the rear baffle in the oven,adjusting the distribution of air volume,and changing the layout of the air outlet.
