摘　　要：采用计算机仿真分析的方法,应用流体力学计算软件Fluent,基于VOF自由液面模型和k-ε双方程模型,对油汀取暖器散热进行数值仿真,得到取暖器内部的温度分布、板面温度分布以及内部流场分布。在油汀取暖器原始环形流道结构的基础上,对取暖器的内部流道进行改进优化,设计出竖向环形流道和横竖向环形流道结构的油汀取暖器,并进行数值仿真。对比分析三种不同流道结构在相同加热功率下内部流场流动均匀性和对外换热性能,得出横竖向环形流道结构的取暖器有最佳换热性能的结论,确定为优化设计方案。目前,桑普电器已将横竖向环形流道结构的油汀取暖器推出市场。Computional simulation method was adopted in this paper to research on heat dissipation effect of sheet type oil-filled electric radiator, based on VOF free surface model and standard k-ε two-equation turbulence model with CFD code Fluent, obtained the temperature distribution and flow distribution inside the electric radiator, temperature distribution on the outside surface of radiator as also. According to the simulation results of original radiator（Gk 1）, optimized the internal flow channel and designed out other two structure radiator, one with annular channel connected by vertical channel（Gk2）, while another with annular channel connected by horizontal and vertical channel（Gk3）. Analyzed the simulation results, we came to the conclusion that the radiator Gk3 dissipated heat with highest efficiency, and chosen Gk3 as final design. Gk3 has been put on the market by Sampux.
