Abstract:

Control cabinet is the geometry space of all kinds of equipment to store and manage data.With the high performance,miniaturization and integration of electronic equipment trends,the cooling capacity of control cabinet affects the performance and service life of the electronic components.On the other hand it is very important to the stability of the system.Based on the review of current research on the cooling of control cabinet,the average temperature of the whole volume is the approximation of the environment temperature.The L64(98) orthogonal table is used to analyze the impact of important factors on its average temperature.The results show that inlet-left and electronic component A1 has the greatest impact on the average temperature.The average temperature obtained from the optimal combination of the range analysis is1.38 ℃ lower than that from the initial layout.The reliability of the control cabinet is improved by optimizing the layout of electronic components,which provides references for cabinet system thermal design.
