| Title: |
Device for Cooling Chemical Smoke |
| Abstract: |
A device and method for cooling chemical smoke for creating a low lying fog
effect comprises first and second chambers arranged in heat exchange
relationship, the first chamber comprising an open-ended conduit adapted
for maintaining a flow of chemical smoke therethrough, the second chamber
adapted for receiving liquid CO.sub.2 under pressure and including vent
openings for venting gases from the second chamber into the first chamber
for maintaining the second chamber at ambient pressure, the liquid
CO.sub.2 transforming to dry ice in situ, and a liquid CO.sub.2 supply
system for connecting a source of liquid CO.sub.2 under pressure to the
second chamber, whereby the chemical smoke flowing through the first
chamber is cooled by the dry ice in the second chamber. Thermal sensor
means sense the temperature in the second chamber and control a liquid
CO.sub.2 flow control valve in the liquid CO.sub.2 supply system.
