Electronic devices have become an indispensable part of our daily life. Especially portable
devices such as mobile phones are one of the things that we always keep with us. Long-term
use of small power tools poses performance problems. Especially in long-term use, the increase
in the temperature of the device is undesirable and directly affects the performance and life of
the device. In this case, it is important to remove the heat from the devices. Although there are
different methods for removing heat, it is widely used to remove heat by convection by adding
fins to hot surfaces. Especially in small-scale devices, heat can be removed from the devices by
convection by using structures called wings and expanded surfaces. For this, large fins with a
surface area are added to hot surfaces. In this study, the effect of groove geometry on heat
dissipation in rectangular fin structure is evaluated. A 3-dimensional rectangular wing model is
created using the student version of ANSYS engineering commercial software. For 400 K
surface and 300 K ambient temperature, the flute-free fin efficiency is 78.11% in the reference
condition. Then, the effect of rectangular, triangular and circular groove design on fin
performance is interpreted. The fin efficiency is compared for each case by adding 1, 2, 3 and
4 rows of grooves in parallel, respectively. It is seen that the highest fin efficiency is achieved
with 4 rows of corrugated fin structure for every 3 geometries. It is determined that the
efficiency for rectangular, triangular and circular trough structure is 83.047%, 83.106% and
82.89%, respectively. It is understood that the highest efficiency is obtained with the triangular
trough.
