Apparatus for cooling a heat source of a motor vehicle

Abstract

The invention relates to an apparatus for cooling a heat source of a motor vehicle, comprising a hollow heat sink, an inlet for introducing a cooling fluid, an outlet for discharging a cooling fluid, a first collecting region for collecting the introduced cooling fluid, a second collecting region for collecting the cooling fluid to be discharged, and an insert part for guiding the cooling fluid from the first to the second collecting region, wherein the first and second collecting regions and the insert part are arranged within the heat sink.

1 . An apparatus for cooling a heat source of a motor vehicle, comprising a hollow heat sink, an inlet for introducing a cooling fluid, an outlet for discharging a cooling fluid, a first collecting region for collecting the cooling fluid introduced, a second collecting region for collecting the cooling fluid to be discharged, and an insert part for guiding the cooling fluid from the first to the second collecting region, wherein the first and second collecting regions and the insert part are arranged within the heat sink. 
     
     
         2 . The apparatus as claimed in  claim 1 , wherein the heat sink is of tubular design, in particular is designed as a flat tube with a first and a second end. 
     
     
         3 . The apparatus as claimed in  claim 1 , wherein the insert part has a smaller longitudinal extent than the heat sink, at least in a certain region or regions. 
     
     
         4 . The apparatus as claimed in  claim 1 , wherein the insert part is designed as a corrugated rib. 
     
     
         5 . The apparatus as claimed in  claim 1 , wherein the two ends are each closed in a fluidtight manner by a closing element. 
     
     
         6 . The apparatus as claimed in  claim 5 , wherein the closing element is composed of plastic. 
     
     
         7 . The apparatus as claimed in  claim 1 , wherein a plurality of insert parts is provided between the first and second collecting spaces.
