Thermal Analysis of Pins and Plate Fin Profiles by using Ansys

Abstract

The engine compartment is one of the essential components of the engine exposed to excessive temperature differences and thermal stress. Fins are positioned on the surface of the cylinder to improve heat exchange by convection. The present study concerns the study of heat exchange between plate fins and pin fins. Pin fins assembled in two shapes (circular, rectangular) with tubular section to allow better improvement of the heat exchange rate. We have optimized the heat exchange rate and optimized all perspectives to achieve a higher heat exchange rate. In the present work, experiments were conducted to determine the temperature fluctuations inside the fins fabricated in three types of geometries (plate fins, circular pin fins, and rectangular pin fins) and study the coherent-state heat transfer was used using ANSYS finite element software to test and approve the results. Temperature fluctuations in different areas of the pin fins are evaluated using FEM, and the plate fin results are compared with the experimentally determined pin fin results in Ansys. The principle implemented in this design is to increase the heat dissipation rate by using wind flow. The main objective of the study is to improve the thermal properties by modifying the geometry, material and design of the fins
