摘　　要：冰柜的立杆在使用过程中由于内外温差的原因,在立杆的表面会出现冷凝现象,即外界的空气遇冷在立杆上凝结成水雾,该现象会导致立杆与玻璃门冻结,从而无法打开玻璃门,影响客户购物。冰柜灯具作为冰柜内部的一个重要组成部分,常见安装在冰柜的立杆部位,它不仅提供了必要的照明功能,还能够在一定程度上提高冰柜的使用效率,达到节能环保的目的。本文中设计了3种防止立杆冷凝的结构,通过不同的灯具与立杆结构组合,对比在各种应用场景下的能耗高低,从而让客户选择最节能的立杆结构。During the use of a freezer,due to the temperature difference between the inside and outside,condensation may occur on the surface of the upright rod.This phenomenon involves the cold air from the outside condensing into water mist on the rod.This condensation can cause the rod to freeze with the glass door,making it dfficult or impossible to open,thereby affecting customers'shopping experience.As an important component inside a freezer,freezer lighting is often installed on the upright rod.It not only provides necessary illumination but also improves the efficiency of freezer use to a certain extent,achieving energy-saving and environmental protection goals.In this article,three designs are proposed to prevent condensation on the upright rod.By comparing the energy consumption of dfferent combinations of lighting fixtures and upright rod structures in various application scenarios,customers can choose the most energy-efficient upright rod structure.
