Louvre for an air-conduction housing of a vehicle air-conditioning system

Abstract

The invention relates to a louvre ( 6 ) for an air-conduction housing ( 7 ) of a motor vehicle air-conditioning system ( 1 ). The invention is characterised in that the louvre ( 6 ) comprises several regions ( 16, 17 ) that directly adjoin one another to facilitate air stratification, said regions being separated by partitions that form part of the louvre ( 6 ).

1 . A louver for an air-conduction housing of a motor vehicle air-conditioning system, the louver having a plurality of regions in order to allow air stratification, wherein the louver has a plurality of regions which are directly adjacent to one another and are subdivided by partitions which are part of the louver.  
   
   
       2 . The louver as claimed in  claim 1 , wherein the louver has two outer regions and a middle region lying between them.  
   
   
       3 . The louver as claimed in  claim 1 , wherein the louver is designed mirror-symmetrically.  
   
   
       4 . The louver as claimed in  claim 2 , wherein the flow cross section of the two outer regions together corresponds to the flow cross section of the middle region.  
   
   
       5 . The louver as claimed in  claim 1 , wherein the louver has at least one region with a configuration in the manner of a drum-type louver.  
   
   
       6 . The louver as claimed in  claim 5 , wherein the region is arranged concentrically with respect to the pivot axis of the louver.  
   
   
       7 . The louver as claimed in  claim 1 , wherein the louver has at least one region which is planar and runs parallel with respect to the pivot axis and/or is curved toward the pivot axis.  
   
   
       8 . The louver as claimed in  claim 1 , wherein at least two of the different regions of the louver extend over a different distance with respect to the circumference of the latter.  
   
   
       9 . The louver as claimed in  claim 1 , wherein at least one region of the louver has, on at least one side, an end running obliquely with respect to the pivot axis.  
   
   
       10 . The louver as claimed in  claim 1 , wherein the louver has a bridge which connects the partitions of a region to one another.  
   
   
       11 . The louver as claimed in  claim 10 , wherein the bridge is of curved design.  
   
   
       12 . The louver as claimed in  claim 1 , wherein the louver has at least one outwardly extending edge.  
   
   
       13 . The louver as claimed in  claim 12 , wherein the edge extends beyond the end faces.  
   
   
       14 . The louver as claimed in  claim 1 , wherein the louver is produced in one piece.  
   
   
       15 . The louver as claimed in  claim 1 , wherein the louver is a plastic injection molding.  
   
   
       16 . A heating or air-conditioning device for a motor vehicle, characterized by a louver as claimed in  claim 1 .  
   
   
       17 . The heating or air-conditioning device as claimed in  claim 16 , wherein the heating or air-conditioning device comprises at least one of the following components: heat exchanger, heating body, evaporator, filter, temperature mixing louver, mixing chamber, one or more flow ducts and one or more control louvers for distributing the air to the outlet ducts.
