The constant progres in the design of electric circuits as well as omnipresence of data-centres with thousands of procesor racks calls for proper thermal management. Using CFD results in the lower operating costs (use of electricity and purchase of cooling equipment) as well as reduced green-house emissions. For small-scale circuits and powerpacks fluid flow and heat transfer simulations give go/no-go answers still at the early design stages, thus lowering development costs and speeding up the design process. For already existing systems you can get key recommendations where to spare sources as well as what the critical regions are.
The use of CFD will give you insight to the following:
- rate of heat transported out of the system
- optimal layout of the cooling devices, heat sinks and ventilation channels in the system
- critical answers at the early design stage (such as if to choose water cooling or air cooling)
