摘要
Abstract
With the intensification of industrial competition,the optimized design of the tube-fin heat exchanger,a core component of dehumidifiers,has emerged as a crucial research area in the industry.In light of the high cost of copper tubes,this study focuses on the application of the"aluminum replacing copper"technology.Taking the 3003 series zinc-sprayed aluminum tubes as the research subject,through a comparison of individual and complete-machine experiments,the following findings were obtained:The single heat-exchange capacity of the aluminum tube condenser with an optimized tooth profile is comparable to that of the copper tube.After being integrated into the dehumidifier system,the nominal dehumidification capacity Cr increased by 3.01%,while the comprehensive energy-efficiency coefficient IEF decreased by only 0.37%.Meanwhile,the material cost of the internal threaded tubes in the aluminum tubes of this scheme was reduced by 60.76%.After deducting the additional costs associated with the copper-aluminum connection tubes and special elbows,the comprehensive cost of the condenser decreased by 14.92%.In the reliability test,the aluminum tube condenser passed the rigorous salt-spray test(1000 hours for neutral/600 hours for acidic)without any leakage.Moreover,the aluminum tubes with a wall thickness of 0.4mm can meet the system's pressure-resistance requirements,and the operational safety standards are met.The research result indicate that the technology of using aluminum tube condensers to replace copper tubes in dehumidifiers is feasible and economically viable,providing key experimental data and technical support for cost reduction and efficiency improvement in the industry as well as the large-scale application of the"aluminum replacing copper"technology.关键词
