Design of longitudinal finned tubes adjusted with the Cesàro curve

Abstract

This paper proposes a process of higher heat transfer efficiency, through a fractal design over Cesàro curve as an extend surface for an exchange tube. Our designs yielded better results applying finite element analysis compared with the smooth surface commonly used in the industry. This new adaptation can be oriented toward applications involving gases and viscous liquids, for devices such as motors, boilers and dissipaters, among others.

Design of passive heat sinks to power semiconductor with the cesaro curve

“…This transistor is taken as an example due to its common use in engineering applications to obtain the necessary current for actuators, such as motors. Initially, the methodology that was carried out to perform the analysis of the heat flow of the suggested heat sink is proposed, where the use of the geometry of the Cesaro curve is explained [21], with the aim of increasing the surface of the heat sink and improving the heat evacuation outward.…”
