I am working on a design project for an engineering class and we are working on a heat exchanger for a circuit board that is currently cooled with cooling fins. We were asked to redesign this using liquid cooling, with something like a cooling plate with a refrigerant tube running through it. We also had the idea of just putting a box over the current fins and running the coolant through the fins. Any ideas on this, has anyone heard of something like this that they could point me at. Or just anything, thanks.
Liquid CPU coolers are used in many PCs. I suggest you first study them which may give you a few ideas. There are also heatpipes, which might just qualify as 'liquid'.
If you have access to a machine shop and welder you can use an aluminum block. Use a milling machine to cut a serpentine channel into one side of a 1/2 inch thick block of aluminum that is approx 3x3 inches. Drill and tap a pipe thread into each end of the serpentine and then weld a plate to the back to seal the block. Pipe the block with hoses to a reservoir and radiator and use a submersible pump in the reservoir to move the water. To avoid condensation problems do not chill the water. instead provide sufficient radiator capacity to allow room air convection to keep the water temp down .'?:
