Device for controlling air supply, in particular to an evaporator with accumulating function arranged in a motor vehicle

Abstract

The invention relates to a device for controlling the air supply to an evaporator ( 6 ) with accumulating function arranged in a motor vehicle, said air coming from a filter ( 2 ) and is transported to the evaporator through a channel ( 3 ). Said channel ( 3 ) consists of three laterals ( 5 ) separated from each other by walls ( 4 ) extending in a longitudinal direction. The inventive device ( 1 ) comprises, in particular two flaps.

1 . A device for regulating the air supply, which regulates the air coming from a filter ( 2 ) through a duct ( 3 ) to an evaporator ( 6 ) with an accumulator function of a motor vehicle, characterized in that the duct ( 3 ) has three duct branches ( 5 ) separated from one another by walls ( 4 ) running in the longitudinal direction.  
     
     
         2 . The device for regulating the air supply as claimed in  claim 1 , characterized in that the device ( 1 ) has two flaps ( 7 ).  
     
     
         3 . The device for regulating the air supply as claimed in  claim 2 , characterized in that the flaps ( 7 ) are arranged at the start of the walls ( 4 ), as seen in the longitudinal direction.  
     
     
         4 . The device for regulating the air supply as claimed in  claim 2 , characterized in that, in normal operation, the flaps ( 7 ) are oriented in such a way that they close the middle duct branch ( 5 ).  
     
     
         5 . The device for regulating the air supply as claimed in  claim 4 , characterized in that the flaps ( 7 ) bear on one another upstream of the middle duct branch ( 5 ), as seen in the longitudinal direction, and form an acute angle with one another.  
     
     
         6 . The device for regulating the air supply as claimed in  claim 2 , characterized in that, in maximum cooling operation, the flaps ( 7 ) are oriented in such a way that they prolong the respective wall ( 4 ).  
     
     
         7 . The device for regulating the air supply as claimed in  claim 2 , characterized in that, in stopped-engine operation, the flaps ( 7 ) are oriented in such a way that they close the outer duct branches ( 5 ).  
     
     
         8 . The device for regulating the air supply as claimed in  claim 7 , characterized in that the flaps ( 7 ) are arranged at an angle of 90°+/−10° to the corresponding walls ( 4 ).  
     
     
         9 . The device for regulating the air supply as claimed in  claim 2 , characterized in that the two flaps ( 7 ) can be controlled in such a way that they make available three different types of cooling operation as a function of their position.
