| 摘要: |
| 对管带式水冷散热器的换热性能进行数值模拟研究，以求提高换热器换热性能，并通过设计实验进行验证。建立模型分别从管带式百叶窗、扁管翅片单元进行全面的性能分析。其中对管带式百叶窗的开窗角度进行了分析，结果表明：散热器散热管带的百叶窗开角在23°～27°之间的散热效果最佳，提出并通过数值模拟验证了一种优化翅片结构的方案，与传统结构对比，散热效果有明显提高。搭建实验台并设计正交试验表研究了不同因素对散热器整体散热效果的影响程度。在本实验研究的范围下，通过多组实验数据分析得出进口水温、循环水流量、风扇转速3种因素对散热器散热量的影响程度为：进口水温>循环水流量>风扇转速。 |

| Abstract: |
| The heat transfer performance of a tube type water-cooled radiator is numerically simulated, and this experiment is designed to verify it. The model is established from the pipe using the louvered and flat tube fin units to perform a comprehensive performance analysis. The louver angle of the tube-belt louver is analyzed, and the results show that the louver angle of the radiator is between 23°~27°, its heat dissipation effect is the best, and a scheme of fin structure optimization is verified by numerical simulation. Compared with the traditional structure, the heat dissipation effect is considerably improved. The test bench was set up and the orthogonal experiment table was designed to study the degree of influence of different factors on the overall heat dissipation effect of the radiator. The experimental results showed that in the scope of this experimental study, the degree of influence of three factors, namely, inlet water temperature, circulating water flow, and fan speed, on radiator heat dissipation is as follows: inlet water temperature > circulating water flow > fan speed. |
