| 目的 对凹版印刷机热交换器结构进行改进设计，以降低能耗。方法 对热交换器进行结构分析、加热管热辐射传热分析、对流传热分析、热损耗分析，借助TRIZ理论对热交换器进行节能设计，并在传热数学算法的基础上对改进方案进行验证。结果 采用发射率为0.05，抛光且未氧化的黄铜作为铜基纤焊翅片管材料，翅片管的产热效率从原来的88.4%提高到96.1%，热风被加热的温度从80 ℃提高到84 ℃。结论 采用肋化系数和发射率恰当的翅片管，可较明显降低热交换器的热辐射率，提高热交换器的产热效率。 |

| The work aims to reduce the energy consumption by improving the design of the heat exchanger structure of the gravure press. By analyzing the structure of heat exchanger, heat transfer by heat radiation of the heating pipe, convective heat transfer and heat loss, the energy saving of heat exchanger was designed with the help of TRIZ theory. Moreover, the improved scheme was verified based on the mathematical algorithms for heat transfer. With the polished and unoxidized brass (emissivity: 0.05) as the material of copper-based brazed finned tube, the heat-producing efficiency of finned tube was increased from original 88.4% to 96.1%. The hot air was heated from 80 ℃ to 84 ℃. The heat radiation rate of the heat exchanger can be reduced obviously and the heat-producing efficiency of the heat exchanger can be improved by using the finned tubes with appropriate finned coefficient and emissivity. |
