| 摘 要： | 机械冷板冷藏车冷板的放冷情况决定了车内货物存放的时间,而放冷过程受到多种因素的影响,从而造成冷板放冷不均匀的现象。本文建立了冷板放冷的数学模型,采用显热容法对冷板放冷的过程进行了分析,研究表明冷板放冷不充分,并对冷板的设计与优化提出了若干可行方案。

| Abstract: | The discharging period that the hold-over plate of hold-over plate refrigerated vehicles was the key to guarantee the goods quantity,but the discharging of hold-over plate was affected by many factors,and it caused the phenomenon that the discharging asymmetry.The models of discharging of hold-over plate refrigerated vehicles were presented in this paper.The method of sensible heat capacity was used to analyze the process of discharging.It pointed out that the discharging of the hold-over plate was insufficiency.And the scherhes were discussed to solve the phenomenon of discharging asymmetry during the period of discharging. |
