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.
