摘　　要：利用碘钨灯模拟自然光照,研究了碘钨灯不同距离处的环境温度,结果表明在距离碘钨灯0.3 m处环境温度为35℃,能够较为真实的模拟夏季环境温度.对碘钨灯光照下沥青混凝土内部的温度场进行了测试,综合确定了发电系统的最佳埋设厚度在距离路表下2～3 cm处.基于塞贝克温差发电原理,利用夏季沥青路面高温热能研制一套无污染、无噪音的发电系统,并分析了此系统对路面的降温效果.该系统能够实现路面热能的转化,并在一定程度上降低路面内部温度,能够延长路面的使用寿命,具有一定的社会效益和经济效益.Adopting iodine tungsten lamp simulate natural light, iodine tungsten lamp is studied in different distance of environment temperature, the results show that iodine tungsten lamp in distance of 0.3 m is 35~C can be a more real simulation of the environment temperature in summer. The temperature field of the asphalt concrete is tested under iodine tungsten lamp lighting, which determined the power generation system the best thickness of buried under the road distance table 2-3 cm. The high temperature heat of the asphalt pavement is utilized in summer through developing a set of no pollution, no noise of power generation system based on the Seebeck thermoelectric effect, and this system on the cooling effect is analyzed. The system can realize the pavement transformation of heat energy, reduces the internal temperature of the pavement to a certain extent, and extends its service life, bringing benefits to the social and economics.
