You do realize that full wave silcon recifiers consist of a diode bridge -- and that when installed neet a HEAT SINK and special HEAT TRANSFER PASTE -- and the standard bolt through the center to the heat sink hardware?
This heat sink approach you will see in every power supply to speak of.
You can get any number of said heat sinks via scrapped out TVs. Being sure to discharge any capacitors involved, the exposed (switching) power supply will have a ton of power transistors or some such bolted to heat sinks all over.
The universal need for heat sinks is so widely known and presumed that their need is not brought up in the packaging -- or by the counter sales person.
While industry uses extruded, finned, aluminum in almost all cases, you can get away with drilling out a 4s cover or some such as a steel heat sink.
The key thing is that you HAVE to have the magic heat transfer paste. This is sold in one-application plastic sqeeze blisters. (dinky, they are) Normally, you have to ask for them. The typical counter sales person will not know what the heck you're talking about.
Do a Google search for such.
(Get them by mail? They would fit in a fat letter, first class.)

Addendum:
LEDs need heat sinks even more massive than diode bridges. These end up getting larger the cooler the LED has to run. The vast bulk of current LED gadgets are dedicated to their heat sinks. Just take a peak. You'll see.
