Cooling system for a motor vehicle or for a stationary internal combustion engine

Abstract

A cooling system for a motor vehicle or for an internal combustion engine includes: at least one heat exchanger, having an inlet and an outlet for a medium to be cooled and an inlet and an outlet for coolant air; at least one fan connected upstream of the heat exchanger; and a connection channel, which is arranged between the fan and heat exchanger, for conveying coolant air to the heat exchanger. A branch line is connected to the connection line or between the individual heat exchangers and removes a partial flow of the coolant air therefrom. The combustion air supplied to the engine is filtered. A Venturi nozzle is connected in the branch line and a suction line is connected to a constriction of the Venturi nozzle and suctions out the filtered particles of the air filter.

What is claimed is: 
     
         1 . A cooling system for a motor vehicle or an internal combustion engine, the cooling system comprising:
 at least one heat exchanger having an inlet and an outlet for a medium to be cooled and and inlet and an outlet for a stream of coolant air;   at least one fan upstream of said at least one heat exchanger;   a connection channel for conveying pressurized coolant air to said at least one heat exchanger, said connection channel being arranged between said fan and said at least one heat exchanger;   a branch line taking a partial flow of said coolant air from and connected to said connection channel or between individual said heat exchangers if said at least one heat exchanger is a plurality of heat exchangers;   a plurality of filters connected upstream from the internal combustion engine or an engine of the motor vehicle, for filtration of a combustion air;   a Venturi nozzle connected to said branch line and having a constriction; and   a suction line connected to a constriction of said Venturi nozzle, for suctioning out a plurality of filtered particles of said air filters.   
     
     
         2 . The cooling system according to  claim 1 , wherein said at least one heat exchanger is at least two heat exchangers connected in series and said branch line is arranged between said two adjacent of said at least two heat exchangers. 
     
     
         3 . The cooling system according to  claim 2 , further comprising a shutoff element assigned to one of said branch line and said suction line.
