冷却水参数对钠钾合金热管传热性能影响
Effect of cooling water parameters on heat transfer performance of sodium-potassium alloy heat pipe
摘要
Abstract
The parameter of cooling water has an important effect on heat transfer performance of sodium-potassium alloy thermosiphon (gravity-driven heat pipe).In this study,the effect of cooling water flow rate and temperature on heat transfer performance of a sodium-potassium alloy heat pipe was experimentally studied.The results show that the flow rate of the cooling water presents a significant impact on the outside wall temperature distribution of the heat pipe when it operates under a relative lower flow rates conditions of 4-18 ml·s-1.But,no further influence of the flow rate is envisioned when the flow rate of the cooling water is more than 18 ml·s-1.Totally,improvement of the flow rate is beneficial for enhancement of the heat transfer performance of the heat pipe.On the other hand,the temperature of cooling water shows very small impact on the outside wall temperature and heat transfer performance of the sodium-potassium alloy heat pipe.关键词
