【摘要】 论述在实验与运行基础上得到的分离式热管元件的理论模型与数学模型。在分析热管内部流动与传热的基础上深入地研究了内部各种热流极限,并取得了理论与实验方面的统一。本文提出了“干度”极限的新概念。认为在各种内部极限中声速极限容易发生,而发生的地区在上升绝热管入口段。更多还原

【Abstract】 A heat flow model of separate type heat pipe elemeht is presented with its mathematic model on the basis of analyzing the experimental data and practical operation. Based on the model, several inner heat flow limits are discussed in metail, and the heat flow model is proved in agreement with experimental results. A new term about inner heat flow limits named "dry limit" is proposed.It is concluded that among various inner limits the presence of sonic limit is most possible, taking place at the entry of upward adiabatic pipe.更多还原
