摘要:
为解决开缝翅片管换热器在实现高效传热过程中流动阻力显著增加的问题，本文设计了一种波纹双向开缝翅片结构，采用数值计算方法对波纹双向开缝翅片进行模拟验证，对比分析未开缝翅片、开缝翅片与椭圆管开缝翅片表面的流动传热特性，深入研究波纹双向开缝翅片管换热器的流动传热及阻力性能受翅片间距tf、开缝高度ts、椭圆长轴与短轴之比e这3个结构参数的影响规律，基于上述3个结构参数，以综合传热性能指标标Nu/f1/3为优化目标，通过正交试验对波纹双向开缝翅片结构进行优化设计，并对波纹双向开缝翅片与未开缝翅片管换热器的传热性能进行对比分析。研究结果表明：在Re=650~5 245范围内，减小tf会提高空气侧Nu和阻力因子f；随着ts的增加空气侧Nu和阻力因子f提高；空气侧Nu和阻力因子f在e减小时提高；在研究范围内，各参数对优化目标Nu/f1/3的影响程度依次为tf>e>ts，综合分析得换热器最优结构参数为翅片间距tf=2.1 mm、开缝高度ts=1.0 mm、椭圆长短轴比e=1.5。优化后波纹双向开缝翅片管换热器较于未开缝翅片管换热器的Nu/f1/3平均增加了9.18%，综合传热性能显著增强。
Abstract:
In order to solve the problem that the flow resistance of slotted fin-tube heat exchanger increases significantly during the process of realizing high efficiency heat transfer, a corrugated bidirectional slotted fin structure was designed in this study. Numerical simulation methods were used to validate the performance of the corrugated bidirectional slotted fins. The flow and heat transfer characteristics on the surface of unslotted fins, slotted fins, and elliptical tube slotted fins were compared and analyzed. The effects of three structural parameters, namely fin pitch, slot height, and the ratio of the long axis to the short axis of an ellipse, on the flow, heat transfer, and resistance performance of the corrugated bidirectional slotted fin-tube heat exchanger were thoroughly investigated. Based on these three structural parameters, the comprehensive heat transfer performance index Nu/f1/3 was selected as the optimization objective. An orthogonal experiment was conducted to optimize the design of the corrugated bidirectional slotted fin structure, and a comparative analysis of the heat transfer performance between the optimized and unslotted fin-tube heat exchangers was performed. The results showed that within the Reynolds number range of Re = 650 -5 245, the air-side Nusselt number and friction factor increased as tf or e decreased, and as ts increased. Within the studied range, the influence of the parameters on the optimization objective Nu/f1/3 was followed the order : tf > e > ts. The optimal structural parameters were determined to be a fin pitch tf of 2.1 mm, a slot height ts of 1.0 mm, and an elliptical axis ratio e of 1.5. Compared with the unslotted fin-tube heat exchanger, the optimized corrugated bidirectional slotted fin-tube heat exchanger achieved an average increase of 9.18% in Nu/f1/3, significantly enhancing the comprehensive heat transfer performance. This study contributed to promoting the application of slotted structures on corrugated fins and provided data support for the optimal design of corrugated bidirectional slotted fin-tube heat exchangers
