摘　　要：基于1MW固体电蓄热的换热系统对其换热过程进行研究分析,从风机效率以及换热器本身结构上分析出热风最低换热温度为250~300℃;在进行换热器设计时为保证换热量,应以最高出风温度参数为基准;还基于1MW机组的换热器设计进行整体和参数化性能分析。此外针对翅片管换热器换热特性,分析其管间距、翅片高度、迎风面积及翅片节距对翅片管换热器换热面积以及出风压力的影响。Solid electric regenerative analysis study on heat transfer process in the system.Based on heat of 1MW solid electric regenerative sys?tem from the fan efficiency and structure analysis of the heat exchanger itself the lowest heat hot air temperature is 250~300℃;at the time of heat transfer area calculation in order to ensure efficiency,should be based on the maximum outlet temperature for the baseline calculation;based on 1MW unit heat exchanger and the overall design and parametric performance analysis.In addition for heat transfer characteristics of fin-and-tube heat exchangers,analysis of the tubes,fin height,frontal area and fin pitch for fin-and-tube heat exchanger heat transfer area as well as the pressure of the wind.
