Reducing the junction temperature of a light emitting diode (LED) to a specific temperature is critical for the luminaires' lifetime and illumination performance. To attain a low junction temperature, a reference radial cylindrical heatsink with was constructed. This model was accepted as a starting point, then nine further models were created using various geometric alterations. The three basic versions with 24 channels: Pin Fin (PF), Pin Vawy Fin (PWF), and Cross-Cut Fin (CCF) were produced by milling machine. These three models were numerically analyzed under the identical conditions and experimental results were confirmed. Then the models were compared in depth using numerical analyses of 3W, 7W, and 10W. The CCF-Y model's surface area has expanded by 24%, and its thermal performance has increased by about 5%, thanks to the radial and axial thin channels that were developed.

将发光二极管 (LED) 的结温降低到特定温度对于灯具的使用寿命和照明性能至关重要。为了获得低结温，构建了一个参考径向圆柱形散热器。该模型被接受为起点，然后使用各种几何变化创建了另外九个模型。具有 24 个通道的三个基本版本：Pin Fin (PF)、Pin Vawy Fin (PWF) 和 Cross-Cut Fin (CCF) 由铣床生产。在相同条件下对这三个模型进行了数值分析，并证实了实验结果。然后使用 3W、7W 和 10W 的数值分析对模型进行深入比较。CCF-Y模型的表面积扩大了24%，热性能提高了约5%，
