摘要
本文对被动式相变冷却系统中远程蒸汽热输运管路对发热体表面温度的影响进行了实验研究。通过研究发现发热体的发热功率、蒸汽管路的几何尺寸、倾斜角度等参数对发热体表面的温度有很大的影响。在本文的实验范围内,为了降低发热体表面的温度,应尽量减小蒸汽的流动阻力,即减小蒸汽管路的长度和管径,增加其倾斜角度。在实际的冷却系统设计过程中,应系统地考虑这些因素的影响,从而更好地优化冷却系统的设计。
The paper is mainly focused on the impact of super-distance heat transport pipeline on heat source temperature in the passive phase change cooling system. Experiment results indicate that the heat power, geometric dimensions of pipeline and tilt angle has an important effect on the heat source temperature. In order to reduce the heat resource temperature, the flow resistance should be decreased by reducing the steam pipeline length and diameter or increasing its tilt angle in the experimental range of this paper. In the process of actual cooling system design, all of the above factors should be considered to optimize the cooling system.
