Looks great indeed! Is this cylindrical style evaps cheaper to CNC on the lathe than otherwise, that why many people use this kind of design?

Thats pricey

**jinu117** · 10-31-2005, 01:41 PM

Not really Johann. Small quantity runs do cost more due to tooling setup cost. Block costs doesn't become really economically feasable till about 50s or 100 orders imo.

**Coyote** · 10-31-2005, 01:44 PM

how tight is the fit between the core and the pipe?

**Gimmpy224** · 10-31-2005, 01:44 PM

not to be the newb here and out of curiosity, how does it work ^_^.

**kayl** · 10-31-2005, 09:25 PM

Sorry but Im not sure that I understand your ?
But heres a drawing.

**Gimmpy224** · 11-01-2005, 07:27 AM

heres a question for ya ^_^

after looking at it for a bit I see the concept you going with.

my question is are you putting the "inlet" starting at the top or bottom?
I ask because at first I figured you would put it at the top, it would run down but how would you get the evap stuff out?
but if you put it at the bottom the evaped stuff would flow upward wouldnt it?

lol, alright and heres a question for me being new, in water cooling you use water to cool, what do you run through the block to cool in phase change? is it the refrigerant like r-22 or is it the oil?

**Haar** · 11-01-2005, 07:37 AM

U got me there.. dont know if its the top or bottom ill just do what I see others doo. Im a noob in this. it is the refrigerant that run through.

Maby like this from the bottom.

**jinu117** · 11-01-2005, 07:40 AM

Most stepper designers seems to prefer bottom inlet top suction. It kind of make sense as you want most evaporation to happen at bottom 1 or 2 plates.

**Gimmpy224** · 11-01-2005, 07:42 AM

yea thats what I was thinkin.
but it didnt look like there was a spot for top suction or a hole for the inlet to run to the bottom.

but I guess you could stick it to the side of it, but wouldnt that like leak the refridgerant?
