Water Cooling LEDs in confined space
Hello everyone, I realised I made a little mistake when building my hood, which is now complete.
Actually is not a mistake, I figured if I had no better option I could just buy 15m of 5630SMD and put them in there, which works anyway but I want to try and do something even better.
The hood measures 55cm in length, 38cm in width split in 2 compartments, the upper compartment keeps all the hardware and the lower keeps all the lighting allowing only one corner gap for any pipes and sensors to access the water.
The problem is I only have 20mm available of space between the ceiling of the bottom compartment and the perspex sheet. Now, the question is, how do you cool LEDs there? Heatsinks would have to be passively cooled since there's definitely no space for a fan in that space.
So I was thinking, I have a custom PC cpu loop I built and I did chill my guppy tank using a TEC plate and a water block. I could use the same principle.
The idea is to have a thing water block, or a number of them, say 10mm thick (which exist, of course) and mount the LED chips straight onto the water blocks themselves, which are either made of copper or aluminium. The water in this loop will be restricted so none of the water will mix with the tank water. In the case of multiple blocks I would simply daisy chain the piping from one into the next and have a pump drive the water to the upper chamber where I can either chill a larger block with a TEC plate or simply use regular fans on a small PC radiator.
What are your thoughts about this? Can I implement this better? Is my thinking correct?
Thanks in advance for your help.
