【摘要】：為確保電腦等電器設(shè)備穩(wěn)定運行,熱設(shè)計是一項很重要的工作。不同海拔高度空氣的密度、壓力等性能下降很多,空氣這些性能的改變對電腦溫度場影響很大。為了能夠準(zhǔn)確的計算分析不同海拔高度地區(qū)電腦機(jī)箱溫度場問題,對風(fēng)機(jī)的性能曲線變化進(jìn)行了分析研究,對建立在海平面上的主要傳熱數(shù)學(xué)模型進(jìn)行了修正,使不同海拔高度溫度場計算更為接近實際情況,為電腦等電器設(shè)備溫度場分析設(shè)計提供了理論依據(jù)。
[Abstract]:In order to ensure the stable operation of computer and other electrical equipment, thermal design is a very important work. The performance of air density and pressure at different altitude decreases a lot, and the change of air performance has a great influence on the temperature field of computer. In order to accurately calculate and analyze the temperature field of computer chassis at different altitude, the change of performance curve of fan is analyzed and studied, and the main heat transfer mathematical model established on sea level is modified. The calculation of temperature field at different altitude is closer to the actual situation, which provides a theoretical basis for the analysis and design of temperature field of electrical equipment such as computer.
