摘　　要：基于用户对冰箱更大使用容积的需求,减薄保温层成为快速增加容积最有效的方式。但面对保温层减小后带来的保温性能衰减,导致冰箱间室内的冷量向外传递引起的凝露问题该如何解决还需要研究。综合现有的防凝露措施,制定多种预设方案,借助仿真工具Icepak,对各个方案进行建模、边界条件设置、温度场仿真,筛选出可行方案;根据仿真结果针对性的制作样机进行实验验证,进而得到防凝露的有效方案;最后再对这些方案进一步对比,从制造工艺性、功耗等方向选择最合适方案,从而避免一开始对所有方案均制作样机再进行验证的方式,缩短验证周期,辅助设计端确定最优方案。Based on the user’s demand for a larger volume of refrigerator, reducing the insulation layer has become the most effective way to rapidly increase the volume. However, in the face of the attenuation of thermal insulation performance caused by the reduction of insulation layer, how to solve the condensation problem caused by the outward transfer of cold volume in the refrigerator room still needs to be studied. Based on the existing anti-condensation measures, a variety of pre-designed schemes were developed. With the help of simulation tool Icepak, each scheme was modeled, boundary condition setting, temperature field simulation, and feasible schemes were screened out;according to the simulation results of the targeted prototype for experimental verification, and then get an effective anti-condensation scheme;finally, these schemes are further compared to select the most appropriate scheme from the direction of manufacturing process, power consumption and so on. In this way, it can avoid the way of making prototype for all schemes at the beginning and then verifying them, shorten the verification cycle, and help the design side to determine the optimal scheme.
