对冰箱换热器使用的管道材料的分析

Analysis of Tube Material for Heat Exchanger of Refrigerator

目的分析冰箱制冷系统中起热交换作用的两器(蒸发器、冷凝器)管道材料铜、铁、铝三者的性能、经济性的对比关系,探讨冰箱管材料用非铜管替代铜管的可行性和应用价值。方法对实际冰箱进行管道材料替代的经济性、性能的对比理论分析与实验研究。材料冰箱、ACR铜管、连续挤压铝管、邦迪管(含焊管)。结果理论和实践都证明冰箱换热器原铜管用管径相近的等长的非铜管替代后,在生产工艺上采取防蚀、锁环连接等相应措施,不会对冰箱的整机性能造成不良影响,且整机材料成本下降。结论得出了用邦迪管、铝管替代在冰箱中使用最广泛的紫铜管,在工艺和技术上可行,并能有效降低冰箱的生产成本。

Objective The relationships between properties, manufacturing process, and economy of the heat exchanger tube materials including copper, steel, and aluminium. The feasibility and the application value of replacement technology for refrigerator tube materials were discribed. The results show that the performance of the refrigerator with the replacement materials will not be lowered, but material and manufacturing cost will decrease.
