Water cooled led system

[Gorgok]

The plate won't be an issue for heat transfer, its the radiator that makes or break everything. If you can't get the liquid cooled then the plate will eventually fail at its job. You might get localized hotter spots especially if you cluster the big heaters, but you would get those even worse on a plain finned heat sink (so proper spacing is still important). I wouldn't bother testing how much it can suck up heat though, and a radiator should say what they hope it can dissipate... Keep in mind their ambient may not be yours.

Once you plumb it up and get it working, measure the change in temperature between the plate and your ambient air temp.

You know your expected power dissipation and geometry.

You can determine the temperature rise due to the LEDs and compare to the temperature reduction you measured for the plate.

So how did this turn out?

I'm going to make one for a unique application (thin profile LED strips 96" x 0.75") and I'd love to learn from your experience first.

Sorry for so long reply, the tank was sold , the light fixture, was running when it lefted, quickly working with it , it worked out as planned, never heard back from them , honesty, I completely forgot ...until now..
