摘要：

The paper presents a finite element modeling based study of various heat sink designs. The main aim of the study is to determine and evaluate solutions with improved heat dissipation by utilization of natural convection. Seventeen different cases both classical and proposed by the authors are studied, where each case is examined under three different heat source (in the case with the proposed study a transistor) powers. Results for temperature of the power source and velocity magnitudes in the studied volume are presented and compared. Experimental verification of the modeling is presented for a number of selected cases.
