The aim of this paper is to numerically investigate the thermal and hydraulic performances of the two heat sinks made ofwavy fins (WFHS). The governing equations fitted with boundary conditions were solved using the finite volume method, and the SIMPLE algorithm for the coupling velocity-pressure. The two-equation model k-ϵ was used to describe the turbulence phenomenon. The effects of wave numbers and the amplitude of wavy fins heat sink on the thermal and flow fields are studied and compared with the plate fin heat sink (PFHS). The results show that the use of wavy fins improves significantly the heat transfer rate, accompanied by a pressure drop penalty.
