A cooling and heating system using a vortex tube (64) is disclosed. The system is attached to an equipment enclosure used for telecommunications, cable television and the like where a cold airstream (66) from the vortex tube (64) is directed to the sealed upper chamber (32) of the enclosure (30), the upper chamber (32) typically containing heat generating electronic components (36, 38, 40, 42). The hot airstream (70) generated by the vortex tube (64) can be used to maintain an elevated temperature which prolongs the life of certain batteries (44) and enhances their efficiency. Cold plates, heat exchangers, air jets and the like may be used in conjunction with the vortex tube to increase the cooling or heating of preselected components or items.

L'invention concerne un dispositif de chauffage et de refroidissement utilisant un tube tourbillon (64). Ce dispositif est relié à une enceinte d'équipement destinée à des systèmes de télécommunication, de télévision par câble, etc. Un flux d'air froid (66) provenant du tube tourbillon (64) est dirigé vers la chambre supérieure (32) hermétiquement fermée de l'enceinte (30), cette chambre supérieure (32) contenant habituellement des composants électroniques calogènes (36, 38, 40, 42). Le flux d'air chaud (70) produit par le tube tourbillon (64) peut être utilisé pour maintenir une température élevée de façon à prolonger la durée de vie de certaines batteries (44) et d'en améliorer l'efficacité. Des plaques de refroidissement, des échangeurs thermiques, des jets d'air, etc. peuvent être utilisés conjointement avec ce tube tourbillon en vue d'accentuer le chauffage ou le refroidissement de composants ou d'articles présélectionnés.
