Heat transfer enhancement through different heat sink/impinging air jet parameters an experimental approach

In the present work, improving the thermal performance of a central processing unit (CPU) cooling system consisting of a plate fin minichannel heat sink exposed to an air jet of impact is accomplished. The height of the impinging air jet duct, the mode of air flow on the heat sink, air blowing mode...
