I have a simple structure I need to design. It is a simple cylinder, roughly 6" in diameter and 8" tall that holds and cools our samples.
The one we are currently using is nothing more than a hollow shell into which two 1/4" tubes are connected at the bottom - one a water inlet and the other an outlet. I have been told that the inside is simple; one of the tubes travels up near the top and the other is a little closer to the bottom. As we pump water through it the water fills and cools the entire stage. The surface would easily reach 1500 degrees C or higher were it not cooled, but is instead operating at between 600 and 1200 degrees C depending on our conditions.
The one we have is pretty mediocre. Firstly, 1/4" connections are simply inadequate to allow the kind of water flow we need. Secondly, the center of the stage is cooled more thoroughly than the edges, which is a no-no. We need to increase its cooling capacity significantly and hopefully make it more uniform.
One idea is just to stick bigger tubes into it. The problem is that temperature gradients on the surface severely limit us. Devising an internal system that would cool more evenly that is also cost effective is something I'm not that familiar with.
Any suggestions? Links to designs? Comments? Ridicule?
