liquid chiller on 24 volt?

[1337mr.hanky]

I have a refrigerator out of a truck, it runs at 24 volts.
Would that be enough to chill a cpu.
Note, i would be satisfied with temps lil bit under 0° load.
It is meant to cool a venice 3500+, will be oc'ed.

We need more details. What kind of "refrigerator"? Do you mean air conditioner?

If you can get some pics that would probably help, too.

sorry, but i havent got the fridge here, so cant take a picture

all i know is that it comes from a volvo

edit: it is an inbuild frigde for in a truck
the cooling unit is loose from the console itself where you put youre drinks in
it is connected with two rubber isolated bendable tubes

You'll need a fairly large 24 volt supply. Probably not worthwhile IMO.

a transformer 220v/24volt

edit, it was connected to a battery, cant be this amp asking.
I think a transfo will supply more than a battery, dont you think?

If it isn't "amp asking" ( ) it isn't powerfull enough mate.

You need atleast a 160W compressor for phase-changing a cpu, any lower and it just can't handle the load. 160W still hardly handles the load.

well, i have two compressors in here, but they look lot different than the unit i'm talking about.
Maybe i can use another fridge, but that one is a lot newer and better, it is a standard looking one, with that one i can replace the compressor by a 220volt one.
Would that be a better id? And than maybe i can fix the older one and put the cooling unit at the new fridge.

Can you follow? Sorry i'm from Belgium, my English isn't that good.

I'm not a pro, I haven't build a system myself. I just did some researching (read: took a fridge appart) and did a lot of reading about phase-change.

You can get a 220v compressor very easy from old fridges. I'd suggest to forget about the transformer idea. Just get yourself a nice 220v compressor.

If you find a nice one just show some pics of it here at Xs and I'm sure there are a lot of people with the knowledge to judge if it's suitable for the job.

Transformers supply AC, batteries supply DC. If its 24v and hooked to a battery, its probably DC (unless you have an inverter on the battery), and will probably be damaged if you give it AC.

You need atleast a 160W compressor for phase-changing a cpu, any lower and it just can't handle the load. 160W still hardly handles the load.

Yeah, 160w is too small for a chiller. Would make a good direct die system though.

He could wire a bridge rectifier in series with the transformer, although like you guys said he'd be better with a 220V compressor, it'll last longer.

i have 2 220volt compressors here, but i will need a condensor and stuff aswell

use the one(s) from the small fridge out of the car?

[alexio]

Even the condensor on a normal fridge is not nearly enough to be used in a phase-change system, let alone a waterchiller, let alone a condensor from a mini fridge

[unixxx]

Use an A/C unit condenser, you can get one for cheap off of eBay.

Hi, you mention truck refrigeration?
What model and make is the refigeration unit?
I fit and repair these things for a living and I know for a fact it can be done, the question is though, how much hassle do you want?

Also to answer an above question, if it's 24v dc you can run it through a 240v > 24v transformer with a rectifier.
Transformer input 240v ac
Transformer output 24v ac

Rectifier input 24v ac
Rectifier output 24v dc.

Do you know how the compressor is driven?
Is the compressor direct feed 24v for drive or does it take it's drive off the vehicle engine?

edit, i am now wondering if the fridge he speak of is a tiny camping thing like in a motorhome for milk and stuff, if it is it probably wont work.
