摘　　要：为解决三氯化铝反应炉炉内高温及余热积累问题,提出一种新型内嵌式SiC-He螺旋管热交换器结构,利用Fluent软件在恒定热源下对换热管中流动换热进行数值模拟,采用正交试验和极差分析的方法研究管径、螺距及横向管间距等对管内流动换热特性和反应炉散热特性的影响。试验结果表明,管径对管内流动换热特性影响最大,螺距影响最小,随着横向管间距的增大,炉内温度分布由对称逐渐趋向均匀。最优参数组合为管径70 mm、螺距100 mm、横向管间距1600 mm。In order to solve the problem of high temperature and waste heat accumulation in the aluminum trichloride reactor,a new type of embedded SiC-He spiral tube heat exchanger structure was proposed.The flow heat transfer in the heat exchange tube was numerically simulated by using Fluent software under the constant heat source.Orthogonal test and range analysis were used to study the influence of pipe diameter,pitch,and transverse pipe spacing on the flow heat transfer characteristics and the dissipation characteristics of the reactor.The experimental results show that the pipe diameter has the greatest effect on the flow heat transfer characteristics,while the pitch has the least effect.With the increase of the transverse pipe spacing,the temperature distribution in the furnace gradually turns from symmetry to uniformity.The optimal parameter combination is pipe diameter 70 mm,pitch 100 mm,and transverse pipe spacing 1600 mm.
