摘　　要：目的研究凹印机烘箱进风管道的结构,以减少管道内的涡流,提高热风流动均匀性。方法建立烘箱结构的三维模型和进风管道的流体域,确定进风系统管道结构数值模拟的可行性研究方案。设计制作烘箱管道结构的实验模型。验证理论研究和数值模拟结果的正确性。结果实验结果表明,流场的速度及压力特性与数值模拟的特征结果具有较好的一致性。结论通过三维结构建模、仿真分析和实验验证,提高了管道的热风效率,节约能耗效果显著。The work aims to study the structure of the air intake duct of the gravure machine oven to reduce the eddy current in the pipeline and improve the uniformity of the hot air flow. The 3 D model of the oven structure and the fluid domain of the intake duct were established to determine the feasibility study plan of the pipe structure numerical simulation of the air intake system. The experimental model for oven pipeline structure was designed and fabricated. The correctness of theoretical research and numerical simulation results was verified. The experimental results showed that the velocity and pressure characteristics of the flow field were in good agreement with the characteristic results of the numerical simulation. Through the 3 D structural modeling and simulation analysis and experimental verification, the hot air efficiency of the pipeline is improved, and the energy saving effect is remarkable.
