周期性喷雾蒸发冷却最佳气-水比的试验研究

Study on optimum air-water ratio of periodic spray evaporative cooling

喷雾蒸发冷却是一种高效的冷却方式。采用试验的方法研究了周期性喷雾蒸发冷却气-水比的变化对换热器换热性能的影响。结果表明,在不同气-水总压力、不同进水温度下,存在一个最佳气-水压力比(1.0),相应的气-水质量比为0.31。

Spray evaporative cooling is an efficient method for cooling. Studies the influence of the change of optimum air-water ratio in periodic spray evaporative cooling process on heat transfer performance of heat exchangers with experimental method. The result shows that under different air-water total pressures and different water supply temperatures, there is an optimum air-water ratio 1. 0. Correspondingly, the mass ratio of air-water is 0.31.
