The study aimed to enhance the heat transport by improving the hydrodynamic structure of the system by changing and restructuring the duct's internal geometry. Modern fins, of the shape ‘V’, have been proposed with different dimensions, and they are periodically arranged over the duct surfaces. The most important steps of this research are the change in the V-fin attack-angle (40°–80°), length (H _b/2, 3H _b/4, H _b, 5H _b/4 and 3H _b/2), and separation length (D _s/2, 3D _s/4, D _s and 5D _s/4), as well as the flow rate (6 × 10³–3 × 10⁴). The study yielded an optimum case for a 40-degree attack-angle, with a factor of thermal enhancement of 2.163 for the highest value of Reynolds number. On the other hand, improving the length of the V-fins or decreasing in the space between them, increases the flow strength by enlarging the recycling cells, which reflects on the hydrodynamic behavior, and changes the heat transfer. The presence of this new model of fins also highlights a hydrothermal improvement ranging between 1.196 and 23.779 percent compared to the previously indicated models, reflecting the effectiveness of the new system of solar heat exchangers with air V-finned ducts.

这项研究旨在通过改变和重组管道的内部几何形状来改善系统的水力结构，从而提高热传递效率。已经提出了具有不同尺寸的形状为“ V”形的现代散热片，并且它们周期性地布置在管道表面上。这项研究中最重要的步骤是V鳍迎角（40°–80°），长度（H _b / 2、3 H _b / 4，H _b，5 H _b / 4和3 H _b / 2）和分离长度（D _s / 2、3 D _s / 4，D _s和5 D _s/ 4）以及流量（6×10 ³ –3×10 ⁴）。研究得出了40度迎角的最佳情况，对于雷诺数的最大值，热增强系数为2.163。另一方面，改善V型翅片的长度或减小它们之间的空间，通过扩大再循环单元来增加流动强度，这反映了流体动力学行为并改变了热传递。这种新的散热片模型的存在还突出显示了与先前指示的模型相比，水热改善幅度为1.196％到23.779％，这反映了带有空气V型翅片管道的新的太阳能热交换器系统的有效性。
