TITLE : Cooling of two fully populated PCB's

DATE : 1999

FOR : Demonstration case



This case represents a real-life model of an electronic box. It has 12 chips dissipating heat and mounted on two PCBs. Flow is forced through the box by a fan. Turbulence is modelled using LVEL turbulence model.

A computational 'smoke' concentration distribution is calculated to see how cooling flow penetrates the recirculation region.
