Aim: To create a non-conformal meshing for the given Icepak object and comment on the quality of the mesh. Introduction: The given Icepak model is a CAD model consists of three assemblies namely Sheet metal heat sink assembly, DIMM's assembly, and a fan guide assembly. Two grilles are attached on adjacent sides as shown…

Aim: To Analyse the heat transfer characteristics in the given cold-plated assembly. Introduction:  The model includes two heated plates, cooled by water circulating inside the cold-plate cavity, as well as by air driven by natural convection externally. Separately meshed assemblies will be employed to reduce the overall…

Aim: To import the given power board assembly (CAD body) to Space claim and convert it into ICEPAK body. Introduction: The power board assembly is consists of several components which are soldered onto the PCB. It is crucial to analyse the flow in the assembly. Hence the CAD object is imported to the space claim and simplified…
