Any such thing?

I'll have a little bridge rectifier and voltage regulator serving
a bicycle hub alternator (6v 4w) and want to use the bike frame
as the heat sink.

My thought was that, if there's such a thing as heat-conductive
putty, I'd just embed the two components in some of it and stick
it to a frame tube.

Thermal epoxy is better than regular epoxy but the conductivity
is very poor compared to copper, and copper is poor compared to
diamond. Might try the suggestion of adding metal filings to regular
epoxy putty. Thermal epoxy is not really putty.

there's a silver-filled thermal epoxy,Arctic Silver.
