采用Fluent和ANSYS Workbench软件对水冷铜基螺线管线圈进行了流体分析及热流耦合分析.得到了水冷铜基螺线管线圈内壁面温度随曲率角和曲面角的变化关系.分析了3种不同流道截面(圆形、椭圆形、三叶形)的螺旋管线圈在同样工况下的出口及交界面的最大温度、平均温度和最小温度,发现流道形状会严重影响螺线管线圈的换热,椭圆截面和三叶形截面的螺旋管线圈相比圆形截面的螺旋管线圈具有更好的冷却效果,如平均壁表面温度均降低了近70℃,管壁上的最高温度也控制在了100℃以内,最大温差也控制在了60℃以内.

Influence of shape on copper base central solenoid's cooling effect

Software of Fluent and ANSYS workbench were used to analysis fluid and thermal coupling in water-cooled copper solenoid coil combining the theory of computational fluid dynamics and finite element analysis. The relationship of inside wall temperature along with the curvature angle and surface angle in water-cooled copper base solenoid coil was obtained. Comparing CS maximum temperatures, average temperatures and minimum temperatures in export and interface of the three different flow channel shape (circle, elliptic, 3 leaf type) under the same condition, it was found that the flow shape will affect the CS heat exchange seriously, elliptical shape solenoid and trifoliate shape solenoid both have better cooling effect compared with circular shape solenoid, for example average wall surface temperature decreased nearly 70℃, the highest temperature on pipe wall and control within the 100℃, the maximum temperature difference is controlled within 60℃.
