Playing with a cooling idea.

This is an idea in the really early stages...

I'm sure you are all familiar with the 6-7 litre mini fridges you can purchase from Argos and the likes. The idea is to somehow integrate the cooling unit into a PC case, with the intention of reducing the internal temperature. Conversely, introduce the cooling unit into the initial part of the airflow into the case, ie. cooler air for the case airflow to work with.

The problems I can see are as follows:

1) Noise? Some of the minifridges use a rather manky fan on a heat exchange to cool the fridge. The effect is supposed to be about 10c-20c cooler than ambient temps. During summer tho, this could be a real advantage to air cooled cases.

2) Heat generated by the cooling unit... I know sounds weird, but most of these systems generate some sort of heat, even if it is just from the power transformer.

3) Insufficient drop in temperature to effectively alter the airflow temp bias. Too much air moving over the "cooling element" and not enough "cool" to make a difference.

The other idea was to use to cooling unit to cool a reservoir of air and then push it over the desired components, either by piping it to say the GPU fan so it is immediately working with cooler air, or to the CPU. Either way, more space but just an idea in the early stages.

The ultimate goal is to reduce the temps without having to buy something like a vapochill or water cooling :D
 
This idea has been asked many times before and i think the main reason it fails to work is that these mini fridges or any fridge of that matter are not designed to keep chilling the air entering the fridge, but to cool it then maintain it by having a seal around the door thus the motor isn't working all the time. So by having a pc taking the cool air, the fridge will be working overtime just to cool the new air inside the fridge.
 
:mad: AAAAAAAAAGHHHH MINI FRIDGES!!!!!!!!!!!!!!!! :mad:

- Can't cope with a constant heat load, your milk does not give out heat, your computer kicks it out by the bucketful.

- Fridges aren't designed to run 24/7, it will die very quickly.

- It just doesn't work, ever.

- As you may have guesed, this comes up a lot :D

Hahaha - yeah, pants...

Figured as much. Just helps sometimes if someone can clarify a thought process - I came up with this one last night at about 4am... sad... :D

Just thought it would be nice to be able to utilise a £19 cooling device in a PC :rolleyes:
 
If you had watercooling surely you could just put the radiator outside in winter :p ? Should cool the water down a bit.

Yeah I used to mount my radiator in the window with cold air blowing into my room, I didn't even need a fan :)
 
haha, I seem to remember someone putting their water cooling radiator into a beer fridge with the water lines in 2 sealed holes on the side. Would still make the fridge work overtime, but less so than having the cooling element in free air...

Now a proper freezer is a different story....

Yeah, thought about a mini freezer or an ice maker, both are about £190 - £300 so then you just get a really decent water cooling system. Aside from that, you get an increase in condensation at a certain drop in temp...

I am not sure it is. They are not supposed to run constantly either (a household refridgerator that is, not something industrial), just maintain a temperature. Obviously one would hold up longer than a mini fridge, but we would need to find out how much load a 100+ watts of constant heat output would put on the mechanism.

Don't get me wrong, I would love it to work!

Mini Fridge idea is pants, they use a poxy heat exchange, really no different to a heatsink with heat pipes...
 
I had a brainwave about cooling the other day, but someone will just probably tell me i'm nuts! What about a large (200mm) 12v fan designed for use in a car, with seperate speed control!

I have one lying around, along with several old pc's (inc 1 x dx66 LOL) and thought about trying to fix it to the side panel somehow!

Good or STUPID idea?
 
didnt some one use a radiator as an actual rad for watercooling?

also i wanna see the people who put there pcs outside.

Having seen this case I had the same idea as you. I've got the original Antec Sonata case which has no decent place to put an intake fan. A nice large 12v fan on the side case should work wonders. It could be big enough to feed air to both the CPU and GFX card.
 
with those fans bigger does not always mean quieter though. Even at relatively low RPMs they'll be quite loud.

it's possible it might work. Be stuffed if I'd know how to figure the airflow tho :) Be more like a paddle boat than a propeller.

I guess it all comes down to physics, to cool a case constantly is always going to take more energy than say cooling a single small area like a CPU heatsink. Targeting a small area is much more efficient than the shotgun approach.

Mini Fridge idea scrapped :) lol
