water cooling for lightbox, 0 light leak

a/v hrdcr junky · 21st January 2004, 07:38 PM

Has anybody thought about using thermo electric modules for cooling their lightboxes yet? I found a water cooling system with a high wattage TEM built into it that seems ideal for such a purpose. Down side seems to be requiring an umbilical for water. Other possible use is TEM with large heatsink, aluminum or copper light box, and standard fan cooling.

It's just not very feasible because you can't remove the heat from the source without convection and radiation through the air medium.

As I have a watercooled PC I've thought about this before. It's possible, but.... If done would be quite inefficient anyway. Might work well for smaller PJ's but, still hard to do for the rewards.

I was thinking about using it for a smaller projector, and I have a walk in closet close to where my projector is going to be so with a reservoir and a salvaged radiator, fan and water pump, I then don't have to endure excessive fan noise. Also, a 200 watt TEM would more than offset the heat generated by a 250 watt bulb so a sealed lightbox would be kept fairly cool. Thanks for your input. By the way, what's your name stranger?

What you could do is let the light pass trough the water and remove the heat in that way.
Water is a very good IR filter, its weird I've never read in this forum about using it as an IR filter.
