Figure 1 shows the starting point for the CFD simulation. The CAD geometry was de-featured and simplified for the model. The air flow within the oven was driven by natural convection due to several power supplies within the oven and two large fans at the bottom of the case. One of the key requests from the client was to minimize the use of fans and to maintain a laminar flow through the cabinet. Our prior CFD consulting work allows us to leverage past “lessons learned” and to quickly develop optimized air flows.
CFD Results from this study were used to optimize the vent locations and provide the final design layout. Subsequent thermal tests by the client showed that the enclosure met the two degree temperature specification with margin.
If such work is of interest, one may find other examples of thermal optimization work of ovens within our general CFD project listing:
