空调铝制换热器标准体系梳理与构建展望OA

With the steady development of the home appliance industry and continuous growth in the production and sales of air conditioners,the sector is prominently plagued by heavy reliance on imported copper resources and drastic copper price fluctuations.Aluminum,featuring abundant reserves,low cost,easy processability and recyclability,serves as the optimal material for the"save copper"initiative in air conditioners,and aluminum heat exchangers have become the mainstream development trend.At present,most domestic standards for heat exchangers are formulated for copper products.The absence of dedicated standards and a fragmented standard system for aluminum heat exchangers leads to obvious deficiencies in raw material control,manufacturing processes,corrosion testing and life evaluation,hindering large-scale industrial promotion.Improving dedicated standards is critical to advancing aluminum substitution for copper.By reviewing relevant domestic and international standardization research,analyzed core defects of existing standards,a four-dimensional standard system covering product specifications,raw material requirements,manufacturing procedures,as well as performance and reliability testing was established.The system realizes full-process standardized control spanning material selection,production and testing,and unifies industrial technical and quality criteria.It provides theoretical and practical references for the standardization of aluminum heat exchangers and supports the green,low-carbon and high-quality development of the home appliance industry.
