ABSTRACT:
A cooling apparatus comprises a chamber containing a pyrotechnic gas generating composition together with an igniter. When ignited, the gas generated by the composition is fed through filters where it is cooled to below the inversion temperature and it is then fed via a heat exchanger to a Joule-Thomson effect throttle where its temperature is further reduced. The gas output from the throttle is fed through a cool chamber where liquid gas collects. The outlet from the cool chamber is fed to the heat exchanger where it serves to reduce the temperature of the gas being fed to the throttle increasing the overall cooling effect.
