Subject: Re: [Astro_IIDC] Cooling Fins


Thanks Milton. I ordered two. It's worth the fourteen bucks to see how well they work. I have a Brass/Copper one of that size with a cooling fan of the same size attached, but haven't tried that yet. I made a Peltier cooler, but it required a large heat sink and fan. Works real well, but does pull lots of power. (enough to require a separate power supply) it overloaded my mount's Pyramid regulated power in about two hours running it with the mount tracking.

Hi Folks;


A fellow on another list mentioned these "stick on" Cooling fins for metal cameras.

As long as they ambient temperature is lower than the camera temperature, they should help dissipate some of the heat. They won't be as efficient as a Peltier cooler, but they don't need power either.


Copper is a better material if you can find cooler / fins built using it instead of aluminum.


TTYL..
