以某车散热器为例,分别进行散热器三维建模、局部撒热器全网格化三维CFD模拟计算分析和整体散热器三维CFD模拟计算。与散热器试验数据对比,模拟计算数据可信,而且可以得到许多试验中难以获得的流动和传热参数,可以直观地观察流场和温度场的变化以及影响因素,为散热器的参数化设计提供有效的办法。 Taking a car radiator as an example, we carry out three-dimensional modeling of the radiator, three-dimensional CFD simulation and analysis of the whole grid of the local radiator, and three-dimensional CFD simulation of the radiator. Compared with the experimental data of the radiator, the simulation data is credible, and the flow and heat transfer parameters that are difficult to obtain in many experiments can be obtained. The changes of the flow field and the temperature field as well as the influencing factors can be observed visually. Provide an effective solution
