摘　　要：以热管为传热元件的换热器具有传热效率高、结构紧凑、流体阻损小、有利于控制露点腐蚀等优点的新型传热元件。随着科学技术进步,热管的应用范围已经从航天、航天器中的均温和控温,扩展到了工业技术的各个领域。将热管传热原理应用于风能致热技术的传热中,作为传热元件,目的在于探讨热管技术在风能致热的热能进输送中应用的可能性,以期获得风能致热的基本数据,为实际应用提供基础。针对自行设计和研发的风车及磁涡流发热系统,通过对多组实验的测试,分析热管在不同蓄水量时的热导率,并对所测的数据进行归纳对比,得到了热管的有关传热规律。实验结果表明,热管的热导率随着蓄水量的增加而增大,其关系呈非线性关系。这对热管技术在风能致热的热能传输中的实际应用具有重要意义。The heat exchanger with heat pipe as the heat transfer element is a newtype of heat transfer elements with high heat transfer efficiency,compact structure,small loss of fluid,and good controlling property of dewpoint corrosion. With the advancement of science and technology,the application range of heat pipe has been extended from temperature control for spacecraft to various other fields of industrial technology. In this paper,the heat pipe heat transfer principle is applied to the heat transfer of wind energy heating technology. The purpose of the heat pipe is to explore the possibility of application of heat pipe technology in wind energy heat transfer,so as to obtain basic data of heat transfer for wind energy induced heat,and provide the fundamental for the practical application. The thermal conductivity of the heat pipe at different water storage capacities was detected and analyzed by experiments.The data were comparatively analyzed,thereafter the heat transfer of the heat pipe was analyzed,and the heat transfer laws of heat pipes were obtained. The experimental results showthat the thermal conductivity of the heat pipe increases with the increase of the storage capacity,and the relationship is non-linear. This is of great significance to the practical application of heat pipe technology in the thermal energy transfer of wind energy.
