摘要
为了优化水冷散热器散热能力,保障其可靠工作,引用了传热学中的基本原理与公式,以散热器外形的机械尺寸、水的强制对流换热系数和水的导热系数作为参数及变量推导了散热器水冷热阻的计算公式。同时为了满足实际应用,开发了一种专用水冷散热器热阻计算和曲线绘制软件,可以显示热阻随参数变化而变化的各种曲线,也可以直接计算显示热阻值。为散热器的设计中参数的优化选择提供直观方便的参考。
In order to enhance the heat-transfer capability of the water-cooled radiator and ensure its reliability,the basic principle and formula of the heat transfer theory was employed.Taking the radiator dimension,water conductivity and water convective heat-transfer coefficient as parameters,the calculation formula of the water cooled thermal resistance of radiator was derived.In order to the practical applications of the radiator,a software to draw the curve and calculate the thermal resistance was developed.It can not only display various kinds of curves that thermal resistance changes with the parameters,but also can directly show the calculation result of thermal resistance.With these functions,the parameter optimizing design method which is of good directive significance can be widely used in engineering projects.
