Abstract:

The objective of this work is to study the heat transfer on rectangular perforatedor non-perforatedfins of different geometries and different materials and to see the influence of these holes on the cooling of the structures. Different simulations using the Nastran/Patran software were carried out. In order to validate the numerical results, an experimental part was carried out. To collect the data of the sensed temperatures, circuits were used based on the Arduino programmable board or the Pic 16F8777A microcontroller programmed by the MicroC and Proteus software. In order to visualize, analyse and control the data, Labview software was used and a personalized interface was created. The results obtained show that by increasing the number and the diameter of holes, the temperature decreases. It is shown that the surface area of ​​the holes is more important than the shape of the holes. There are certain hole distributions that give better results compared to others.
