摘要

摘要: 基于汽车散热器性能试验的相关标准及方法,研制一种高精度汽车散热器散热性能试验台,试验结果表明空气侧与介质侧换热量比值范围为0.96~1.00,满足并且优于散热器标准试验台的测试标准。根据试验结果和理论研究,建立百叶窗翅片散热器数学模型,在MATLAB环境下设计根据散热器计算长度确定出口状态的迭代算法,编写仿真程序,建立性能仿真模型,仿真结果与试验结果吻合较好,空气侧换热量相对误差<4.5%,介质侧换热量相对误差<4.7%,空气侧压降相对误差<7.6%,介质侧压降相对误差<9.5%。

Abstract: Based on the related performance test methods and standards of automotive radiator, a high-precisionperformance test bench was designed. The heat transfer rate in the range from 0. 96 to 1. 00 for both sides issuperior to the criteria of test stands standard. The complete mathematical model fore louvered fin automotiveradiator has been established on the basis of the analyzed and tested results, the simulation program and simulationmodel have been compiled with Matlab by using an iterative algorithm according to the gauge length to determinethe discharge state of automotive radiator. It was proved that the simulation results were in a good agreement withthe tested results, the heat exchange relative error of air-side was less than 4. 5 %, the heat exchange relative errorof medium-side was less than 4. 7%, the pressure drop relative error of air-side was less than 7. 6%, the pressuredrop relative error of medium-side was less than 9. 5%.
