## 1 Introduction  
The demand for induction hobs continues to grow due to their advantages over gas and vitro-ceramic alternatives. Unlike conventional methods, induction hobs directly heat cookware using electromagnetic fields. They feature a flat, non-magnetic glass-ceramic surface with copper coils underneath. When a current passes through these coils, a changing magnetic field forms. If a ferromagnetic pan is placed on top, this field generates eddy currents inside it, creating heat through resistance. The generated heat then transfers to the food or liquid efficiently and precisely. Since heat is generated directly inside the cookware rather than on the hob surface, induction hobs offer rapid heating and precise temperature control. However, they require cookware with a magnetic base, such as cast iron or stainless steel. Recently, various numerical and experimental methods have been used to model thermal and fluid behavior. Techniques like the Lattice Boltzmann Method (LBM), Discrete Element Method (DEM), and Particle Image Velocimetry (PIV) provide detailed insights into microscale flows and particle dynamics. Yet, these methods often demand specialized setups, limiting their practical use in household appliances. In contrast, computational fluid dynamics (CFD), based on Navier-Stokes equations, is a reliable and widely used approach for simulating turbulent, forced-convection flowsin electronic cooling. This study uses CFD analyses performed with FloEFD, which applies the finite volume method (FVM) and the k-\(\epsilon\) turbulence model. This method was selected for its ability to simulate steady-state thermal and fluid behavior in compact systems, its alignment with fan P-Q curves, and its easy integration with CAD during product development. Additionally, CFD enables parametric studies and allows validation through air velocity and temperature comparisons, as shown in this work [1; 2; 3]. Numerous studies have investigated induction hobs in the literature. For instance, [PERSON] et al. [4] visualized the temperature and flow distributions on induction and gas hops using CFD, comparing the heat distribution characteristics of both hob types. [PERSON] et al. [5] examined the induction heating process through numerical and experimental methods, simulating the induction heating of steel workpieces with temperature-dependent and -independent analyses. Within the electronic systems of induction hobs, heat accumulates in the electronic components during operation. Therefore, a well-designed ventilation system is essential for the safe and sustainable use of induction hobs, comprising primarily a fan and a heatsink. Studies on heatsink design have shown various approaches. In recent years, emerging heatsink geometries such as topology-optimized or porous media-based structures have gained considerable attention, particularly for high-performance thermal management. While such approaches offer significant potential, this study focuses on geometries compatible with current domestic appliance production methods. Future work may explore these innovative designs in more detail, especially as additive manufacturing capabilities advance [6; 7]. [PERSON] et al. [8] developed an analytical model to calculate the average heat transfer rate in forced convection for slotted fin heatsinks. [PERSON] et al. [9] experimentally investigated the heat transfer and flow performance in plate-fin heatsinks by adding dimples and protrusions to enhance heat transfer. In the literature, statistical and experimental approaches have also been studied. [PERSON]. [10] focused on optimizing the cooling performance of a Parallel-Plain Finned (PPF) heatsink module. Due to the compact structure and high performance requirements of electronic devices, effective management of the heat generated is critical for the reliability and lifetime of the devices. In this study, the effects of the design parameters of the PPF heatsink module on the cooling performance were investigated using the Taguchi method and Analysis of Variance (ANOVA).
