热管在热传导方面具有无可比拟的优势,但在沥青混凝土路面内传热降温仍处于室内试验研究阶段。热管传热效率受沥青混合料结构、石料种类、热管埋深和热管类型等因素的影响。通过室内模拟试验,测定埋热管沥青混凝土内部温度随不同因素影响的变化规律,同时揭示了热管对减缓沥青混凝土升温、加速降温、提升高温稳定性的积极作用。 Heat pipe has an unparalleled advantage in heat conduction, but heat transfer and cooling in asphalt concrete pavement is still in the stage of indoor experimental research. Heat pipe heat transfer efficiency by the asphalt mixture structure, stone types, heat pipe depth and heat pipe type and other factors. Through the indoor simulation test, the internal temperature of buried pipe heat affected by different factors was measured. Meanwhile, the positive effect of heat pipe on decreasing the temperature, accelerating the temperature and increasing the high temperature stability of asphalt concrete was also revealed.
