Abstract
A two-stage cooling system configured to cool an interior of an enclosure includes a cabinet, a first vortex tube secured within the cabinet, and a second vortex tube secured within the cabinet. The cabinet defines a venting chamber. The first and second vortex tubes each include a hot pipe within the venting chamber and a cool gas delivery pipe extending outwardly from the cabinet. The first and second cool gas delivery pipes are configured to deliver cold gas to the interior of the enclosure. A separate thermostat may be operatively attached to each vortex tube and extend outwardly from the cabinet to be positioned within the interior of the enclosure. Additionally, first and second dampening sleeves may be secured around at least a portion of the first and second hot pipes, respectively, such that the dampening sleeves dampen noise produced by the vortex tubes.
