摘　　要：机械冷板冷藏车冷板的放冷是保证货物质量的一个关键,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；指出了冷板内共晶溶液的传热性能不佳是影响冷板放冷不充分的主要因素,并探讨了解决冷板放冷过程中出现的放冷不均匀现象的方案。The discharging period that the hold-over plate of hold-over plate refrigerated vehicles was the key of guaranteeing the goods quantity, but the discharging of hold-over plate was affected by many factors, and it aroused the phenomenon of 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 points that the low function of heat transfer of eutectic is the main factor that affects the hold-over plate to discharging insufficiency. And the projects were discussed to solve the phenomenon of discharging asymmetry during the period of discharging.
