Description

Heat Sink Cooling Problem Description

The present product deals with the simulation of a heat sink and cooling. In the present model, a surface as a heat source with a heat flux equivalent to 600,000 W.m-2 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. 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 that 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 solid material used in the model is aluminum because aluminum has a very good heat transfer property.

Assumption

Several assumptions are used for the present simulation of Heat Sink Cooling:

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

Geometry & Mesh of Heat sink

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 semi-symmetric. The present model consists of a heatsink containing a solid part and a fluid part. The solid section has a series of parallel grooves that the fluid flows through these grooves. 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.
