Abstract: Influencing factors on ice-melting of loop heat pipe (LHP) was tested and sensitivity coefficients of various factors were calculated based on indoor snowmelt pavement structure model. The influence factors included heating mode, fluid temperature, pipe diameter, pipe distance and heating power. The results show that: LHP has excellent heat transferring effect and the maximum warming rate of road surface can reach 8 ℃/h, while the influence scope is limited at horizontal direction. The heat is continously transported from LHP to road surface and inner pavement. The heat utilization rate of direct electric heating is higher, and the ice thickness only affects the melting time of ice and snow. Road surface is sensitive to heating power and spacing, and 4cm depth is sensitive to fluid temperature and pipe diameter. The heating power sensitivity is the strongest, and the fluid temperature sensitivity is the worst; the thicker the pipe diameter and the larger the spacing, the sensitivity increases.

摘要: 基于室内融雪路面结构模型,对加热方式、流体温度、管径、管间距、加热功率等影响环路热管融冰雪效果的因素进行试验测试,并计算了各因素敏感性度系数。结果表明:环路热管具有优异的传热效果,路表最大升温速率达8 ℃/h,但水平方向影响范围有限,热量由热管不断向路表和路面内部传递;直接采用电加热方式热量利用率更高,冰层厚度仅影响冰雪融化时间;路表对加热功率、间距敏感,4 cm深度对流体温度、管径敏感;加热功率敏感性最强,流体温度敏感性最差,管径越粗、间距越大,敏感性增加。
