摘　　要：依据无霜冰箱蒸发器化霜原理,针对现有化霜系统存在的问题,提出了改进的设计方案,把铝管加热化霜改为石英管辐射化霜,取消了化霜恒温器固定盒;通过对改进前后的比较与分析,证实了改进的可行性;分析表明,通过改进设计提高了冰箱工作的可靠性和经济性。Based on the defrosting principles of frost-free refrigerator-freezers evaporator, this paper presented improved design scheme of defrosting system, including aluminum tube conducting defroster being converted into quartz tube radiating defroster and removing thermostat holddown groove. By comparing the new design with the original,it was proved that the improved design is feasible. The analyzed results of feasibility were shown that the reliability of refrigerator -freezers using new system is improved and economical efficiency will be remarkably enhanced.
