a PhD thesis at the College of Engineering at the University of Basrah discussing (simulation design and fabrication of microwave heat sinks for electronic devices)
The thesis  presented by the student Ammar Muslim Hadi
Proposing, manufacturing and testing new forms of copper-finned micro-heat sinks with dimensions that have been carefully studied. Some designs for these heat sinks were in new forms that were presented for the first time. Laser technology was used in the manufacturing processes. Initially, these heat sinks were selected on a transistor in an electronic circuit
Simple to simulate the heat dissipation process freely. The wind tunnel is precisely manufactured for the purpose of studying heat transfer, heat transfer coefficient addition to the Nusselt number, in addition, he performed a numerical simulation of these dispersions using the Komsol program and with a turbulent flow.
The thesis aims to focus on the performance of heat sinks with different geometric shapes in two different modes of heat transfer, whether by natural or forced convection.
The thesis concluded different performance in the two patterns of natural and forced convection. In natural convection, it was found that the greatest percentage decrease in the temperature of the transistor can be observed through two unusual designs, namely the leaf-shaped fin LSF and the drop-shaped fin IDP, on the other hand showing the fin Zigzag SWF minimum drop
percentage in temperature
Transistor In forced convection, the greatest value of the Nusselt number is recorded through the IDP fin
