I'm looking for some advice from an ME or anyone who understands heat transfer,convection, etc.
I'm currently laying out in Inkscape a top panel for an audio amplifier I'm building. Now, my question lies in the orientation of the exhaust fins that I will be having laser cut out of acrylic.
There is a need for these exhaust fins so the cold air from below the heatsink has a place to go.
Now, in regards to the image below, does it make more sense to have:
- Situation 1, where the exhaust fins (green) are perpendicular to the heatsink fins?
- Situation 2, where the exhaust fins are parallel to the heatsink fins?
