摘要: 针对某款集成灶,采用三维数值模拟方法对集成灶风机出风口和出风管区域流场结构进行了分析。通过分析原模型A的模拟值和实验值,改变成双侧进风,优化蜗壳型线和出风方向,再对原型A和优化模型B、C、D进行数值模拟及实验对比分析。结果表明,在机箱和出风管保持形状位置不变状态下,最优模型D性能较原型大幅提升。其中左侧出风量提升2.49 m3/min,噪声只增加0.24 dB(A);右侧出风量提升1.18 m3/min,噪声下降0.30 dB(A)。两侧出风量相差0.39 m3/min,出风量差进一步缩小,均匀性得到明显改善。

Abstract: The flow field structure of an integrated cooking appliance fan outlet and exhaust pipe is analyzed by three-dimensional numerical simulation. According to the analysis results of model A numerical simulations and experiments, improved models, which involves double inlet, fan curve and direction of export are obtained. The comparison of numerical and experimental results for the original model A and improved model B, C, D shows that the performance of the improved model D is higher than the original model A. The results show that air flow on left side is increased by 2.49 m3/min, and the noise level is only increased by 0.24 dB(A). The air flow on right side is increased by 1.18 m3/min, and the noise level is decreased by 0.30 dB(A). The air flow difference on both sides is 0.39 m3/min. So the air flow uniformity of model D is improved obviously.
