Özet

Performance is extremely important in electronic devices. Especially during use, any pause or freezing may cause undesirable results. This is even more important for critical tools. Although there are many parameters that affect performance in electronic devices, warming is one of the most important parameters after the production process. In particular, the device temperature, which affects the service life and performance, should be kept under control and should not exceed the maximum level. This study is about fin structures added for cooling in electronic devices. They are structures that aim to remove more heat by convection from a hot surface by increasing the fin surface area. It is impossible to add a cooling system, especially for smallscale electronic structures. In this case, it is tried to improve the convection effects by providing more surface area with fin structures. In the study carried out, the effect of the parallel rectangular groove structure in the fins on the heat dissipation is evaluated with the 3D CFD model using the student version of ANSYS engineering commercial software. First, the efficiency of the rectangular fin is measured at 400 K fin bottom temperature and 300 K ambient temperature. Then, the effect of the parallel rectangular grooves to be placed on the wing on the heat removal from the wing and the efficiency of the wing is interpreted. For a heat convection coefficient of 20 W/m2K, the efficiency is 78.11% for the non-corrugated fin in the reference state. With 1 row of rectangular grooves positioned in parallel, the fin efficiency increases by 5% and becomes 82.375%. It is seen that the wing efficiency increases with rectangular grooves placed in 2,3 and 4 rows, but the increase tends to converge.
