Electronic ignition mounting plate for Conversion

The power transistor and the heat sink are on the top side of the module. I believe that is where most of the heat is generated.

Most heat sinks are big hunks of metal. Sounds a lot like a firewall. As big as the firewall is compared to the size of the module, seems like it would be an “infinite” heat sink.

I suppose a case could be made that there is an improvement in airflow, but I wonder if anyone has any data to support that is a functional improvement.

Maybe my analysis is bad, but I am curious if the mounting plates actually improve heat transfer, or if this is just a gimmick that sounds good on the surface.
