摘要
针对以往散热管道散热效率不高的情况,利用Solidworks建立散热管道的三维模型,并在模型外施加实际试验条件下设定的边界条件,再通过ANSYS的热流耦合模块对管道模型进行有限元分析,得出在特定散热管道尺寸条件下的散热器出口温度。调整管道尺寸,得到新的出口温度。通过多次调整管道尺寸,得到出口温度的数据组。最后根据分析所得的数据组,采用对分法调整管道尺寸,实现了散热管道尺寸优化的预期目标,为今后类似尺寸的优化设计提供了参考。
According to low heat dissipation efficiency of heat dissipation pipe, building a 3D model of heat dissipation pipe with Solidworks, the boundary conditions enacted under actual experimental conditions are stressed outside the model. The outlet temperature of the heating-radiator under the condition of special heat dissipation pipe size is obtained through finite element analysis on the pipe model using ANSYS thermal fluid coupled module. The new outlet temperature is obtained through adjusting the pipe size. The data group of the outlet temperature is obtained through adjusting the pipe size many times. Finally, according to the data group after analyzing, the pipe size is adjusted using bisection method to realize the expected target of heat dissipation pipe size optimization. And it provides references for the similar size optimization design in the future.
