分离式热管传热及水动力特性的可视化研究

VISIBLE EXPERIMENTAL STUDY OF HEAT TRANSFER AND HYDRODYNAMIC CHARACTERISTICS OF SEPARATE TYPE HEAT PIPES

本文通过玻璃分离式热管模型,对分离式热管内部流动、传热等进行可视化实验观察,并着重就几个主要影响因素,如外界工况、充液量、结构布置等,对分离式热管加热部分和冷却部分流动及传热的影响进行了分析、观察,叙述和揭示了分离式热管内部的流动和传热规律及其机理.

Experiments on inside flow and heat transfer of the separate type heat pipes were carried out through the model of the heat pipe made of glass. It was observed and analysed that the flow patterns and heat transfer of the evaporator section and condenser section were influenced by some main factors, such as outer operation conditions, working liquid rate, the structure of the heat pipe and so on. The paper described the regularity and mechanism of the flow and heat transfer inside the separate type heat pipes.
