Manual heat sink design analysis
Manual heat sink design analysis
(OP)
Hi I am designing a heat sink. I want to analyse the design manualy without using any software. I want to design the heat sink closer to its required application parameters so that much analysis is not required. I know a good analysis would make a good design. It is ok if my design is one step below that. Is there any tutorial out there anywhere which would help me to design a heat sink to its required parameters. I am a recent graduate & I've never done something like this before. I am on my own and there is no senior engineer on this field to get any help.
Any help/tip would be greatly appreciated.
Thanks in advance,

that said heatsink design isn't that difficult. Get your hands on a good heat transfer text and there should be a chapter on fin design. Incropera and DeWitt's fourth edition stays on my desk. A good copy of Schlichting's "Boundary Layer theory" (out of print but still available all over. Try Ebay) will get you through the natural and forced convection issues
