Analysis of heat transfer and structure design for heat carrier transfer pipeline to hot-press machine with double energy

利用ANSYS有限元软件对单源载热体(导热油加热,水冷却)和双源载热体(热油和蒸汽同时加热,冷油和水同时冷却)的热压板孔道结构分别进行传热仿真分析,得到相应的温度分布云图及热压板温度随时间的变化曲线.传热仿真分析结果显示,在同样条件下用双源载热体把热压板加热到140℃所用的时间比单源载热体少200 s,双源载热体加热热压板板面最大温差1.2℃;双源载热体冷却所用的时间比单源载热体少330 s,板面最大温差2.6℃.表明采用双源载热体产品可达到优等品的生产要求.同时设计了与双源载热体相适应的载热体输送管道结构.

The simulation analysis of heat transfer of the same channel structure of hot-press platen with different heat carriers such as single energy heat carrier （using thermal oil as heating source,using water as cooling source） and double energy heat carriers （using thermal oil and vapor as heat energy,using water and cool oil as cooling energy）,were done by ANSYS finite element software.The temperature distribution cloud contours and time-temperature connection curve of hot-press platen were gained respectively.The simulation analytic results showed that the heating time of heating hot-press platen to 140 ℃ by double energy heat carriers was 200 s shorter than that of single energy heat carrier in the same condition and the highest difference in temperature of hot-press platen was 1.2 ℃.The cooling time by double energy was 330 s shorter than that of single energy and the highest difference in temperature of hot-press platen was 2.6 ℃.In a word,the double energy heat carriers could reach the requirment of high grade quality.The transfer pipeline structure fitting for heat carrier with double energy was designed.
