I had an idea for a cheap sorta evap.
Here's the general design,
2" square copper plate, around 1/6" thick or so, a 1.75" peice of pipe maybe an inch tall, brazed to the plate in the center, then drop in as many 8mm copper beads (with holes thru them for necklaces) into little area and braze em in. Then put on a cap over the pipe and braze it shut, of course attach a peice of pipe to the cap for suction and once ur all brazed string a capillary line in there thru maybe some of the holes towards the base area.
Any ideas?
yeah blockage lol. imagine the worst case scenario where the "copper beads" get suck up the suction or pass the suction if it gets through...Boooom

Thats why you drop them in one at a time while brazing and braze em up. Maybe a pain to get out oxidation, but you could try with a high velocity water jet or the like then bake the water vapor out of the block...

If 1 of the beads gets into the compressor nothing is gonna happen the bead is just gonna sit at to bottom of the compressor forever.

^^ True, but still any ideas if the evap would work. Yes its multiple paths but its just all expansion room, and gas woudl get out of the evap quickly but still lots of surface area and mass.
oic i thought the balls will get stuck in somewhere odd and cause the compressor to cease operation. Anyway i still think the internals of a phase system should be kept free of any objects to ensure safety.U never know what is going to happen :D.

it cirtainly wouldn't work well in a tower, but as a bench system it may work, and the vaccum pump would take the water out, you could use a piece of steel screen to keep the beads in the evap.
and as a upright evap you could have the piece of tube angled up so the freon would pool at the backplate and evaporate, made a northbridge block like this and will try to test it once i get a nother compressor.
[hoping the fridge shop will let me back after i get cirtified {parents are wondering if they should let me}]

I don't think poeple realize what I'm saying, so ill type it agian.
You'd braze all the beads in, they would not be able to move.

I read it but nothing to add. :rolleyes:

yeah but if in a horrible accident that you had a bad braze and one fell out you would know you would be safe, and you could braze the tube to the base with a higher temp. brazing rod then drop the beads in then heat the block and melt like a whole rod of lower temp. brazing rod in, or use soft solder, that would be so much easier than brazing each on
EDIT:
oic i thought the balls will get stuck in somewhere odd:lol: :bounces: :rotf: sorry, had to point that out before someone else did

wow no one is reading the thread....
Brazing isn't what he's asking, it's performance...

It would depend on the orientation of the evap. If the cpu and evap are horizontal, and the braze is solid, it should do quite well. IMHO
Edit: Oh and about the brazing. If you get them all hot enough, and just feed the rod in liberally, it will fuse solid. As for the oxidation, I have found that a quick blast from my CO2 tank which is liquid feed and has no regulator on (safety nazis stay away) cools the block down fast enough to completely eliminate oxidation.
