摘要：

由于3D打印技术越来越成熟，模具的冷却流道可以用3D技术加工成螺旋式，该结构流道可以成倍地提高模具的热效率。利用传热学理论，对新型螺旋式流道结构和传统型直通式流道结构进行传热分析，根据两种流道结构特点和相关的边界条件建立数学模型，进行了数值计算和相关热力学软件仿真。研究结果表明，在两种流道结构的散热面积、流体介质总流率都相等的条件下，新型螺旋式流道的加热（冷却）速率是传统型直通式流道的加热（冷却）速率的3～5倍，仿真结果和数值计算的结论一致。

As the growing maturity of 3D printing technology, the cooling channel of mould could be processed into spiral type by the 3D technology, which could doubling improve the thermal efficiency of mould. The theory of heat transfer was used to analyze the heat transfer of the new spiral channel structure and the traditional straight-though channel structure. Mathematical models were established according to the structural characteristics and the related boundary conditions of two kinds of channels, and the numerical calculation and related themodynamic software simulation were carried out. The results show that the heating (cooling) rate of the new spiral channel is 3-5 times that of the traditional straight-though channel under the condition that the heat dissipation area and the total flow rate of fluid medium for the two kinds of channel structures are equal. Also, the results of simulation are consistent with those of numerical calculation.
