摘要
种植机风道是家用智能种植机进行新风换气和温度控制的关键组件之一,风道的结构设计直接影响各出风口的风向流动和风量分配,进而影响种植机的风路循环效果和温度均匀性。本文以采用贯流风机驱动的封闭式智能种植机为例,首先对现有种植机箱体结构进行简化,通过CFD仿真对风道及箱体内部的流场进行数值模拟;然后根据数据结果对原始设计方案进行结构优化;最后通过实验测试的结果表明:经过优化后的风道改善了箱内各种植层的风向流动和风量分配,使得种植机内部空气温度更加均匀。
The planter duct is one of the key components of the household intelligent planter for fresh air ventilation and temperature control.The structural design of the duct directly affects the wind direction flow and air volume distribution of each outlet,and then affects the wind circulation effect and temperature uniformity of the planter.In this paper,the enclosed intelligent planter driven by cross flow fan is taken as an example.Firstly,the box structure of the existing planter is simplified,and the flow field inside the duct and box is numerically simulated by CFD simulation.Then the structure of the original design scheme is optimized according to the data results.Finally,the experimental test results show that the optimized duct improves the wind direction flow and air volume distribution of each planting layer in the box,making the air temperature inside the planter more uniform.
