ABSTRACT:
A cooling system configured to cool an interior of an enclosure includes a cabinet, and a vortex tube secured within the cabinet. The cabinet defines a venting chamber. The vortex tube includes a hot pipe within the venting chamber, and a cool gas delivery pipe extending outwardly from the cabinet. The cool gas delivery pipe is configured to deliver cold gas to the interior of the enclosure. A dampening sleeve may be secured around at least a portion of the hot pipe, such that the dampening sleeve dampens noise produced by the vortex tube. Additionally, at least one dampening sheet may line at least a portion of the interior and exterior surfaces of the cabinet.
