摘要

为了研究微孔雾化器的喷雾冷却性能,搭建了微孔雾化器的喷雾冷却试验台,研究了雾化量、喷雾高度、雾化器驱动频率等参数对冷却性能的影响。研究发现微孔雾化器的具有较好的冷却效果,雾化量对对冷却性能的影响基本呈线性关系;雾化性能随着喷雾高度的增加而降低;雾化器的驱动频率对冷却性能基本没有影响。研究结果可以为微孔雾化器的冷却应用提供参考。
        In order to study the spray cooling performance of the micro-aperture atomizer, a spray cooling test bench was set up, and the effects of the parameters such as the atomizing rate, the spray height, and the atomizer driving frequency on the cooling performance were studied. The results show that the micro-aperture atomizer has a good cooling effect, the atomization rate has a linear relationship with the cooling performance; the atomization performance decreases with the increase of the spray height; the driving frequency of the atomizer has almost no effect on performance. The research results are helpful to the cooling application of micro-aperture atomizers.
