Structural assembly for centrifugal fan rotor housing

Abstract

The present invention refers to a structural assembly for centrifugal fan rotor housing capable of optimizing the air flow in its interior. Such optimization is due to the existence of a pneumatic circuit ( 5 ) which disposed inside said structural assembly for centrifugal fan rotor housing comprises at least one essentially spiraled virtual orientation ( 53 ).

1 . Structural assembly for centrifugal fan rotor housing, comprising at least one cap ( 2 ), at least one base ( 3 ) and at least one rotor ( 4 ), and defining at least one pneumatic circuit ( 5 ) provided with at least one air inlet ( 51 ) and at least an air outlet ( 52 );
 said structural assembly for centrifugal fan rotor housing being CHARACTERIZED in that:   the cap ( 2 ) comprises in its posterior surface, at least one essentially sinuous wall ( 21 ) defined in accordance with said pneumatic circuit ( 5 );   the base ( 3 ) comprises in its frontal surface at least one essentially spiraled recess ( 31 ) and defined in accordance with the pneumatic circuit ( 5 ); and   the pneumatic circuit ( 5 ) comprises at least one essentially spiraled virtual orientation ( 53 ).   
     
     
         2 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said base ( 3 ) comprises, in its frontal surface, at least one essentially sinuous wall ( 32 ) defined in accordance with said pneumatic circuit ( 5 ). 
     
     
         3 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said base ( 3 ) comprises, in its posterior face, at least one mechanical reinforcing rib ( 33 ,  36 ). 
     
     
         4 . Structural assembly, in accordance with  claim 3 , CHARACTERIZED in that at least one mechanical reinforcing rib ( 36 ) is disposed at the essentially spiraled recess ( 31 ). 
     
     
         5 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said cap ( 2 ) comprises, in its frontal surface, at least one mechanical reinforcing rib ( 22 ). 
     
     
         6 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said cap ( 2 ) is attached to said base ( 3 ) by means of fixing elements ( 6 ). 
     
     
         7 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said essentially spiraled virtual orientation ( 53 ) of the pneumatic circuit ( 5 ) is essentially based on logarithmic function. 
     
     
         8 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said essentially spiraled virtual orientation ( 53 ) of the pneumatic circuit ( 5 ) is essentially based on Fibonacci sequence. 
     
     
         9 . Structural assembly, in accordance with  claim 1 , CHARACTERIZED in that said spiraled virtual orientation ( 53 ) of the pneumatic circuit ( 5 ) is essentially based on golden function.
