查询词典 cooling equipment

The results indicate that the cooling rate of melt droplet that can not break further depends not only on its diameter, but also on its position in atomizing chamber. As a result, the same sized particles in different positions show different cooling rates and two different kinds of microstructures. The cooling rates of melt droplets range from 104 to 108 K/s, and the critical cooling rate for glass formation of Al-Ni-Y is about 105 K/s. Moreover, the corresponding maximum diameter of amorphous particles is 25 μm, which accords well to the theoretical analysis results. The new approach, reflecting the complexity of close-coupled gas atomization objectively, is available and effective to evaluate the cooling behaviors of close-coupled gas atomization.

结果表明：在一定的工艺条件下，紧耦合气雾化存在多种破碎模式，熔滴的冷却速率因直径、雾化位置的差异，相同直径熔滴经历结晶和非晶化2种不同冷却行为；依据Al基合金粉末的粒度分布和微观结构，结合熔体的雾化过程及冷却模式，确定熔滴冷却速率的上、下限；实验得出熔滴的冷却速率为104~108 K/s，Al-Ni-Y合金的非晶化临界冷却速率为105 K/s，能形成非晶态的熔滴最大直径为25 μm左右，实验结果与理论分析结果较吻合，比较客观地反映紧耦合气雾化的复杂过程。

This study experimentally examined the heat transfer characteristics of 180-deg turning duct under forced convection cooling, as the internal cooling structure of 180-deg turning duct is widely applied to industrial cooling. While several perforated holes were separately arranged within the 180-deg turning duct, the cold flow of better cooling capability was guided in the first duct into the second duct in advance, so as to reduce the overheating of the second duct and realize uniform cooling of the machine members. In addition, the centrally separated holes could yield extra turbulence against the air current, and the interaction between bypass air current and mainstream may possibly improve the overall heat transfer capability.

本研究系以实验方法探讨180度转弯通道於强制对流冷却下之热传递特性，180度转弯通道之内部冷却构型在工业冷却之应用非常广泛，本研究设计将180度转弯通道其中间分隔具多个穿孔，目的在将第一流道内具较佳冷却能力之冷流提早引入第二流道，以减少第二流道产生过热情况，如此可使得机件获得均匀之冷却，此外，中间分隔上之穿孔对气流也具有额外之扰动效果、流经穿孔之旁通气流与主流交互作用，这都有可能增益整体热传能力。
