Forced Gas Quenching

Greetings All

Thinking about the current thread on nitrogen quenching, I have picked up 
on a few points:

1) Using a sealed gas system
2) Using a jet to achieve supersonic gas flow through the gap
3) Bottled gas discharging to atmosphere vs recircultated gas.

Stop me if I'm on the wrong track, but how about using the guts of a 
refrigerator for this?  High pressure/small bore tube leads into gap 
manifold producing gas blast, gas passes through heat exchanger, then back 
to pump and back to the gap again.  Would this not provide both quench and 
cooling?

It would obviously help if we were to use a high-dielectric strength gas 
which is also a refrigerant.

Equipment would not be too large or expensive.



Cheers
