Fan

Abstract

A fan includes a main body with a vertical development with respect to a support base on which it is positioned in a condition of use, and defining an internal housing compartment. The fan includes an air suction and distribution unit, disposed inside said compartment, cooperating with apertures made on the main body in order to take in air from outside the main body, and at least one longitudinal aperture for the emission of a stream of air toward the outside. The fan also includes a channeling element positioned in proximity to the at least one longitudinal aperture.

1 . A fan, comprising a main body having a hollow column shape with a vertical development with respect to a support base on which it is positioned in a condition of use, and defining an internal housing compartment, said fan comprising an air suction and distribution unit, disposed inside said compartment, cooperating with apertures made on the main body in order to remove the air from outside the main body, a conditioning device configured to thermally modify the condition of the stream of air distributed by said suction and distribution unit, comprising at least one longitudinal aperture, with a vertical development, for the emission of a conditioned stream of air toward the outside, disposed in a rear zone, during use, of the hollow column-type main body, and a channeling element positioned in proximity to the at least one longitudinal aperture and cooperating with it to determine the exit of said conditioned stream of air through said at least one longitudinal aperture, and divert the conditioned stream of air exiting from the main body so that said conditioned stream of air adheres to an external surface of said main body and is conveyed toward the front of the fan, remaining substantially in contact with said external surface between a lead-in edge, where the conditioned stream of air adheres to the external surface, defined by the position of said longitudinal aperture and a separation edge disposed in a front zone of the fan, opposite the rear zone, said fan being provided with heat insulation means configured to prevent, or at least limit, the onset of a heat exchange between said conditioned stream of air exiting from said main body through said at least one longitudinal aperture, and the stream of suctioned air inside said main body, said heat insulation means being associated at least with an internal surface of said main body, opposite said external surface in contact with said stream (Wo), and extending from said lead-in edge toward the front part of the fan. 
     
     
         2 . The fan as in  claim 1 , wherein said heat insulation means extend at least for most of the area comprised between said lead-in edge and said separation edge. 
     
     
         3 . The fan as in  claim 1 , wherein said heat insulation means extend for a zone having a longitudinal extension substantially corresponding with that of said longitudinal aperture. 
     
     
         4 . The fan as in  claim 1 , wherein said heat insulation means comprise a layer or a panel of insulating material disposed in contact with said internal surface of said main body. 
     
     
         5 . The fan as in  claim 1 , wherein said heat insulation means comprise a layer or a panel of insulating material disposed in contact with an inactive surface of said channeling element facing toward the outside of the fan, and opposite an active surface in contact with said stream of air. 
     
     
         6 . The fan as in  claim 1 , wherein said conditioning device is positioned in a substantially central zone of said main body and is connected to said longitudinal aperture by means of an exit channel, and in that said heat insulation means comprise a layer or a panel of insulating material disposed along the edges of said exit channel of said conditioned stream of air between said conditioning device and said longitudinal aperture. 
     
     
         7 . The fan as in  claim 1 , wherein said heat insulation means also comprise a layer or panel of reflecting material, configured to minimize the absorption of the heat radiation of said conditioned stream. 
     
     
         8 . The fan as in  claim 7 , wherein said layer or panel of reflecting material is disposed on an active surface of said channeling element facing toward said longitudinal aperture. 
     
     
         9 . The fan as in  claim 1 , wherein that said heat insulation means comprise layers or panels of insulating material with thermal conductivity less than 0.10 W/mK. 
     
     
         10 . The fan as in  claim 1 , wherein said heat insulation means comprise layers or panels of insulating material with thermal conductivity less than 0.5 W/mK. 
     
     
         11 . The fan as in  claim 1 , wherein said heat insulation means comprise layers or panels of reflecting material with a reflection coefficient higher than 0.8. 
     
     
         12 . The fan as in  claim 1 , wherein said heat insulation means comprise layers or panels of reflecting material with a reflection coefficient higher than 0.95. 
     
     
         13 . The fan as in  claim 1 , wherein said heat insulation means can be applied by means of mechanical attachment, structural integration, or application of surface finishings.
