Wine coolers or refrigerators are not build for that. The Compressor will (constantly) overheat and then die ....

That's right.
But let's stop and think for a while:
I've seen very stupid cooling solutions, including BFL's take on that matter.
It's quite well known that cool air is heavier than hot air.
Hot air always flows naturally upwards.
The Jalapeño pushes cold air from the top and pushes it downwards to the other side's venting.
But that's not even close to smart...
When my Jalapeño arrives, I intend to remove the case (and fan, possibly) and create a vertical wind tunnel with two cones, to create a Venturi effect on the heat sink.

The fan will move to the top cone, forcing the air out or to the bottom cone, forcing the air in (haven't decide or tested yet).
If possible, I'll have the hot air exhaust to the exterior using an H pipe chimney:

I think this is going to be one of those 'sounds better in theory' kind of things. Still give it a go and report back with pics of your crazy creation, of course! I suspect that the restriction of flow from the pipe head alone will cancel out most of the hot buoyant air effect you are trying to exploit. I would confidently say that it WILL have some airflow but the question becomes "is it sufficient?".

I am not sure about the H-chimney design, I think the two 90 degree bends the flow would have to make would limit the momentum and flow rate of the rising air. I would almost bet BTC that a single straight tube of constant diameter would be better.

EDIT: I re-read your idea about putting the fan on it too. I was thinking you meant it would work passively. I suspect you will still find that having this contraption with the fan(s) on top will still be worse than just having the fan next to the heatsink as normal.

Where are all the process engineers / industrial chemists to model this scenario for us??? Do we have to bribe them with BTC lol?

Was this your motivation behind your idea by any chance? http://en.wikipedia.org/wiki/Solar_updraft_tower
