The current work proposes a novel cooling system for two conductive panels using a T-shaped channel with sinusoidal wavy vortex promoters under nano-enriched magnetic field effects. A finite volume method is used to analyze the influence of Reynolds number ( \(Re = 50\) –300), magnetic field strength ( \(Ha = 0\) –50), magnetic field inclination angle ( \(\gamma = 0\) – \(90^\circ\) ), vortex promoter amplitude ( \({\text{A}}_{{\text{f}}} {\text{ = 0}}\) –0.2), and wave number ( \({\text{N}}_{{\text{f}}} {\text{ = 1}}\) –5) on the cooling performance of the panels. Two different cooling systems are used as Conf-1 and Conf-2. The vortex size is controlled by the Re and magnetic field parameters, while in the Conf-2 cooling system, a vortex develops near the right junction. At the maximum Re, Conf-2 provides a \(2.9\;^{^\circ } {\text{C}}\) reduction in temperature for the horizontal panel, but leads to a \(4.4\;^{^\circ } {\text{C}}\) increase in temperature for the vertical panel compared to Conf-1. At maximum strength of magnetic field, the upper panel temperature increases by \(13.2\;^{^\circ } {\text{C}}\) in Conf-1 and \(1.2\;^{^\circ } {\text{C}}\) in Conf-2, while in the lower vertical panel it decreases by \(1.3\;^{^\circ } {\text{C}}\) in Conf-1 but increases by \(8.5^\circ\) C in Conf-2. From the lowest to the highest inclination angle, the upper panel temperature changes by + \(5.9\;^{^\circ } {\text{C}}\) (Conf-1) and - \(4\;^{^\circ } {\text{C}}\) (Conf-2), whereas the lower panel varies by + \(0.1\;^{^\circ } {\text{C}}\) and − \(5.2\;^{^\circ } {\text{C}}\) , respectively. The cooling performance of each panel is profoundly influenced by the amplitude and wave number of the wavy baffle, but the extent of temperature reduction depends on the cooling configuration. A model based on artificial neural network (ANN) predicts the average surface temperatures of each panel as functions of Re and magnetic field parameters which enables identification of optimal cooling conditions; under these optima, sinusoidal baffle significantly lowers temperatures, achieving up to \(67\;^{^\circ } {\text{C}}\) reduction for horizontal Panel in Conf-2 and up to \(35\;^{^\circ } {\text{C}}\) in Conf-1 cooling system.
