Featured Thing!

Description

It is a small back flow chiller. Through the outer cavity you are able to pump a hot or cold fluid. Through the inner tubing you may pump a fluid which in turn gets heated or chilled by the other fluid. The two fluid are except for the transfer of heat isolated form each other. They will not mix.

the openscad design file seems to be missing :(...looks very cool though :)

Same thing as a heat exchanger or some subtle difference?

Indeed the conductivity is poor. Printing it in metal would be the next step. I just need a makerbot which I would convert to print in metal. ;)
I mean, how hard could it be ? :-D

Also I don't know the capabilities of a makerbot in such detail as to optimize the thickness of all walls.
Just wish I had a more capable CAD System, a version of this cooler with a inner structure like a peano curve would rock.

Instructions

If you want to print one, use the BackFlowChillerComplete.stl file. This file is not a version of the chiller with a cutaway to expose the inner structure of the thing.

I don't know how well the makerbot will cope with the overhang of the top covering. If to much sagging occurs you could alway add some more support pillars in the sagging area to keep it level.

Interesting design, but i think the plastics thermal conductivity is too bad to make it effective enough.
And about your STL render problem: Maybe try to import the files in blender, and export them out of there again. Did work for my stl-files that had rendering and skeinforge issues.

:'( thingiverse can't render my stl files. WHY!! THINGIVERSE TELL ME WHY!!?!

No big thing, just added a picture.

did you just change the ending to .stl? or did you actually convert it?
