Investigation on Heat Storage Characteristics of Vanadium Tailings/Carbon Foam/Organic Matter Composite Phase Change Materials
摘要
Abstract
Using carbon foam(CF)as supporting materials,paraffin(PW),palmitic acid(PA)and stearic acid(SA)as phase change main materials and Panzhihua vanadium tailings(VT)as thermal conductivity enhancer,vanadium tailings/carbon foam/organic composite phase change materials were prepared by constant temperature impregnation and pouring method.Digital thermometer and infrared image were used to test the heat storage and release time and temperature distribution of composite phase change materials.The test results show that when the carbon foamed/organic composite phase change material is prepared by the constant temperature impregnation,the adsorption rates of carbon foam to PW,PA,and SA are 66％,72％and 72％,respectively.The filling rate is low.Therefore,after mixing organic matter with micron-level TV and then pouring it into the carbon foam pores,the filling effect is better.The thermal storage shortened time of CF/PW,CF/PA and CF/SA composites with the addition of 2％,1.6％and 0.8％of micron-level TV was shorter than that of the corresponding composites.When 0％～3％of micron-level TV was added to three kinds of carbon foamed/organic composites,the difference between the center temperature and the highest temperature was 2.7～3.8,6.4～7.8 and 5.0～11.9℃ higher than that of pure organic material.The test results of thermal storage shortened time and temperature field distribution show that micrometer TV is the best in CF/PW composite phase change materials.关键词
