Description

The present product deals with the simulation of a heat sink cooling by ANSYS Fluent software.

In the present model, a surface as a heat source with a heat flux equivalent to 600,000 W/m2 is located at the bottom of the model, which is responsible for continuous heat generation.

On this surface, a solid object with several rows of parallel grooves is located to perform the cooling process of high-temperature surfaces. The solid material used in the model is aluminum because aluminum has a very good heat transfer property.

Heat Sink Methodology

The 3-D geometry of the present model is designed by the Design Modeler software. Since the present model is symmetric, the model is designed as semi-symmetric. The present model consists of a heat sink containing a solid part and a fluid part.

The meshing of the present model is carried out by ANSYS Meshing software. The mesh is structured in a uniform and conformal manner and the element number is 168480.

The solver is Pressure-Based, the simulation is Steady-State, and the gravity effect is ignored.

Heat Sink Conclusion

On this solid body and in the space between these parallel grooves, water flows in order to transfer heat from the solid surfaces to water, so the presence of these grooves increases the contact surface between the solid body and the water flow and thus the cooling process is strengthened.

The pressure drop via the heat sink is clear through the pressure contour. Also, the temperature shows the main role of the mentioned grooves in the cooling process. The water flows velocity increases and the temperature decreases when passing through the heat sink grooves.
