Abstract
This paper reports numerical study results with respect to the thermal performance of various hybrid fins (HFs) and a pin fin (PF) passively cooled under natural convection state. Investigated HFs are a basic hybrid fin (BHF), a hollow hybrid fin (HHF), and a solid hybrid fin (SHF). CFD models for both HFs and the PF have been developed to explore their thermal performance under various heat dissipations. Thermal performances of fins have been analyzed by quantifying array-based heat transfer coefficients, $h_a$, and mass-based heat transfer coefficients, $h_m$, for each fin. Study results show that $h_a$ of the SHF is 23% greater than that of the PF. $h_m$ of the HHF is found to be even 140% greater than that of the PF, and the HHF is found to be 40% better than the BHF in terms of the mass-based performance, $h_{m{\cdot}}$.
