Abstract: Given the significance of improving heat transfer in thermal engineering equipment, researchers in this field have developed numerous methods for heat transfer improvement. These methods are classified as active and passive. Several researchers consider the use of forced vibration in improving heat transfer to be one of the most significant topics in the applied field. This is because some thermal equipment has this feature due to its nature. As a result, the current study emphasizes research dealing with mechanical vibration in enhancing heat transfer in free convection conditions. The results of these studies agreed that heat transfer by free convection and vibration contributed to improving the thermal performance of thermal equipment compared to its at-rest condition. These studies' findings indicate an increased heat transfer coefficient as frequency is raised, particularly in forced convection heat transfer. However, the limited vibration amplitude has an impact on heat transfer. In some studies, the fin slope was studied in addition to vibration. These studies showed that fin tilting reduces heat transfer optimization value with fin tendencies that produce vibrations. Furthermore, while the vibration process does enhance heat transfer capacity, it is accompanied by certain drawbacks. These include the generation of noise, which can disturbance to humans, as well as potential damage to mechanical components of the equipment.
