Cooling my chiller

nice, i'm looking forward to seeing how it runs.

i think a nice big top forced intake with vents on the side for passive exhaust should do the trick. i was thinking along the line of maybe an electric car radiator fan for the intake (it runs on 12V, flows alot of air and you say noise isn't much of an issue) or a small array of 120mm fans on the top with some sort of cover on the intake so it can't take rain water in....this sort of idea



and then something like this for the exhausts because the flaps only open when air is moving so when the intake fan isnt on they'll close themsleves and stop anything coming in through them.

 

I like kitts idea. you will want to aim it around the compressor or make some liquid coils around it

 

*roffles* now thats a bit silly, watercooling the chiller for a watercooling setup

EDIT: *thinks about it a bit more* although it might just work.....

 

the heat exchanger has 2 fans on it at the mo... i have 2 extra fans at the moment. 1 sucking air in directly in front of the heat exchanger and one pulling air out of the box at the other side. both have vents like the one with the flaps above.

I was thinking of just having 2 pulling air out of the box with a double size vent and having a big vent in front of the heat exchanger with a shroud.

the first thing you suggest is unworkable as my son will rip it off in a breath (18 months old) or wack it untill it falls off.

watercooling the compressor is not a good idea - it would add too much heat to the loop and as nothing is 100% efficient it would go to critical mass and burn a hole to the centre of the earth.

 

so if i read what your saying right you want, to have a shroud that allows to two fans on the back of the exchanger to pull air in straight from outside without a forced intake then have the one already as a forced exhaust and then add to that the one that was a forced intake to make two exhaust fans.

well if thats what you were proposing then it sounds like it should be fine, i would just make sure enough air that is cool enough is moving past the compressor cause the air out the back of the heat exchanger will be fairly warm and if the ambient temperature is high anyway it could very well push the compressor past is safe working temp which is about 45C on those i think

ah yes, you've got to be careful...the last thing you want is one of the compressors attaing critical mass as things can go even more badly than you feared....it has the potential to form a quantum singularity and cause the whole universe and everything in it to fold in on itself till it all exists at the same point in space and time before going 'pop' out of existance and thats the end of everything, which could be rather tedious

 

it is deffo hotter than 45 - i couldnt keep my hand on it. but it would fire up just if i opened the lid on the garden box..

maybe if i had the two spare fans pulling air out of the box next to the compressor on the side of the box rather than the end... there isn't anything over that side that produces heat anyway.

so all i have to do to stop the end of the universe is have a couple more fans.. hmmm. OK i'll get them.

x1900 back soon can't wait to put this one to bed.

 

FLASH!....i mean, needmorstuff! your alright but we only have 14 hours to save the earth! [/CHEESY FLASH GORDEN QUOTE]

yeah, um sorry bout that i couldn't resist it....anyway, yeah, putting the fans next to the compressor sounds like a better plan than having them tucked down away by the res (which is isulated anyway). that should do it although it might more effective at cooling the compressor if you put two fans for a forced intake in the front to blow the coolest possible air over the compressor and then just have a passive exhaust vent down near the res end of the box, just a thought though.

 

What if you just ran a second small loop around the compress with another circtuit? And I have noticed that AC units release a lot of heat from the coils so if you have that air moving over the coils into the case and inot the compressor you are heating the whole thing with the compressor. Route the exhaust through the case. Use ducting or something. THen get 2 fans to air over the whole thing.

 

hes got two fans pulling air over the condenser an what i was suggesting was to have two fans blowing over the compressor straight from out side as well and then place an exhaust vent so the air being pulled in just finds its own way out (i.e the exhaust vent since it'll be the easiest way out)

 

^^what he said. going to have 2 fans blowing cool air straight over the compressor... and I may even duct the air from the 2 heat exchanger fans directly out of the box through the back wall as it is an inch or so away from the wall.

 

That is what I suggested. SO iono

 

I think that is all you will need, although a top exaust fan of some sort would help remove the heat that is pooling at the top of the case.

 

nice. not small though
