基于参数敏感度分析的管片散热器再设计方法
A Redesign Method Based on Parameter-sensitivity Analysis for Plate Fin-and-tube Radiators
摘要
Abstract
To set up a solid mapping relation between the internal structure of a radiator and its heat dissipation performance to enhance the system' s performance in some bad working conditions, such as in an over-loaded or high-temperature environment, a redesign method based on parameter-sensitivity analysis is introduced here. According to the theoretical descriptions on the heat-transfer process given by forced-convection heat transfer theory, a mathematic model is built to weigh the significance of the radiator's design parameters to the system's heat dissipation performance. A sensitivity factor is derived by examining the effect of the variation in each parameter to the output of the system which quantitatively describing the range of the parameter's influence to the system's performance. The new design method is expected to be a reference for radiator design under certain circumstance.关键词
