Abstract

The paper describes a novel approach to solving heat transfer problems in geometrically complex systems. In the present approach, instead of simulating the detailed complex geometry, templates of components and devices are assumed rather than working on actual components. By varying the template dimensions a systematic study on the effects of geometrical configurations on cooling airflow and heat transfer is made possible. The application of the approach is illustrated drawing examples from cases of heat spreader designs and heat transfer analysis of portable computers. The purpose of the study is to develop a methodology whereby the packaging designer is freed from the task of performing detailed numerical analysis. Currently available numerical analysis tools such as computational fluid dynamics (CFD) codes are given a role in an undertaking to create databases from which fast design formulas are developed.

一种设计复杂传热系统的新方法:散热器和便携式计算机设计案例研究

本文描述了一种解决几何复杂系统传热问题的新方法。在目前的方法中，不是模拟详细的复杂几何形状，而是假设组件和器件的模板，而不是在实际组件上工作。通过改变模板尺寸，可以系统地研究几何结构对冷却气流和传热的影响。以便携式计算机的散热器设计和传热分析为例，说明了该方法的应用。该研究的目的是开发一种方法，使包装设计师从执行详细的数值分析的任务中解脱出来。目前可用的数值分析工具，如计算流体动力学(CFD)代码，在创建数据库以开发快速设计公式的工作中发挥了作用。
