摘　　要：螺旋扁管是以椭圆直管为基础,通过旋转螺旋而成型的一种新型高效强化传热管型。采用数值模拟的方法对不同结构参数的螺旋扁管进行了研究,分析了螺旋扁管内介质流场状况、传热及流阻特性。由模拟结果可知,螺旋扁管的传热性能优于椭圆管和圆直管,且扭曲和压扁程度对螺旋扁管的传热性能影响较大。Spiral flat tube is based on the elliptical straight tube, through the rotation of the spiral forming a new type of highly efficient heat transfer tube type.The numerical simulation method was used to study the spiral flat tube of different structure parameters. The flow field, heat transfer and flow resistance characteristics of the spiral flat tube were analyzed.According to the simulation results,it is concluded that the heat transfer performance of the spiral flat tube is better than that of the elliptical tube and the straight tube.The degree of twist and flattening has a great influence on the heat transfer performance of the spiral flat tube.
