Interesting Heatsink for LEDs

I thought thermal pipes are for CPUs

Will that fit in my Maglite?

I'd opt for a big copper plate.

HAHAHAHAHA

I am ahead of the times!



That was just to test out the LED..... but still it was on a thermal pipe.

I always thought that heatpipes would be good bases for PnP automotive bulbs...

Is frostytech just trying to sell thermal pipes??

I thought the virtue of thermal pipes was the ability to connect a heatsource to a distant heatsink, such as in laptops. In this application, there's nothing stopping them from attaching the LEDs directly to the heatsink fins via a fairly modestly sized chunk of aluminum. (right?)

Interesting application though. Getting 50W of heat out of an auto headlight might be interesting, considering that the environment under a car's hood is already pretty warm. Maybe a better solution is to add a small radiator in front of the existing engine coolant radiator, and just use liquid cooling for the lights?
