A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device’s working surface area and the amount of low-temperature fluid that moves across its enlarged surface area. Based on each device’s configuration, we find a multitude of heat sink aesthetics, design, and ultimate capabilities. You can see a straight fin heat sink in the image at the top of this article and a flared fin heat sink in the image below.
In this tutorial, you will learn how to simulate a Heatsink using Ansys Fluent. In this first video, you will see how to create the geometry and the mesh using DesignModeler, Ansys Meshing and Ansys Fluent.

Ansys CFX – NACA 4412 (Structured Mesh)
The NACA four-digit wing sections define the profile by:
First digit describing maximum camber as percentage of the chord.
Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.
