【摘要】 为缩短充冷时间,提高保冷能力,降低能耗,实现蓄冷保温箱性能的提升。提出一种锯齿形结构新型蓄冷板,并对比了平板蓄冷板与三种不同尺寸新型蓄冷板的蓄释冷性能。同时研究了蓄冷保温箱配送过程中,四种蓄冷板布置方式(顶部布置、四周布置、并列布置、重合布置)下箱体的保冷性能。结果表明:新型蓄冷板与平板蓄冷板相比蓄释冷更快,其中新型蓄冷板3性能最高,其蓄释冷完成时间与平板蓄冷板相比分别缩短了39.1%与39.3%;蓄冷板布置方式对箱体保冷性能存在很大的影响,其中并列摆放时温度场均匀,且平均温度最低,只有281.6 K,效果最好。更多还原

【Abstract】 This study aim to shorten the charging time, improve the cold preservation ability and reduce energy consumption, in order to improve the performance of the cold storage incubator. A novel cold plate with zigzag structure is proposed, the charging and discharging performance of the flat cold plate and three different sizes of novel cold plates are compared. At the same time, the performances of the cold storage incubator during the deliver progress under four cold plate arrangements(top arrangement, surrounding arrangement, side by side arrangement, coincidence arrangement) are studied. The results show that the novel cold plates have faster cold charging and discharging rate than the flat cold plate, and the novel cold plate 3 has the best performance because its time to reach the complete charging and discharging is shortened by 39.1% and 39.3% compared with the flat cold plate. It is found that the arrangement of cold plate has a certain influence on the cold preservation performance of the cold storage incubator. Under the side by side arrangement, the cold preservation performance of the cold storage incubator is the best because of its uinform temperature field and lowest average temperature which is only 281.6 K.更多还原
