The present invention relates to a cooling module () for a motor vehicle, comprising at least one heat exchanger () and at least one duct () comprising an air inlet () of the cooling module (), the duct () being configured to convey cooling air from the air inlet () towards the heat exchanger (), characterized in that the duct () comprises fastening elements () configured to fasten the heat exchanger () to the duct ().

Cooling module for a motor vehicle

The present invention concerns a cooling assembly () for a motor vehicle, comprising at least one first heat exchanger () extending mainly in a first plane (PI), at least one second heat exchanger () extending mainly in a second plan (P) and at least one protective grid () for protecting the second heat exchanger (), the first heat exchanger () and/or the second heat exchanger () being carried by a frame (), characterised in that the at least one protective grid () of the second heat exchanger () forms a one-piece part with the frame ().

Cooling assembly for a motor vehicle

A heat exchanger for a motor vehicle includes heat exchange bundle with a plurality of stacked tubes inside which a first heat-transfer fluid circulates, and an end flange arranged on each side of the stack of tubes which brazed to the heat exchange bundle. The end flanges include a flat body with a first surface that faces an aerodynamic element and a second surface, the brazing surface, opposite to the first surface and brazed to the heat exchange bundle. Attachment tabs receive the aerodynamic element and are arranged on the sides of the flat body, the attachment tabs projecting in the opposite direction to the heat exchange bundle. At least one extension of the flat body extends in the same general plane as the flat body and is arranged between a pair of attachment tabs on a same side of the flat body.

Heat exchanger with brazed end flange

Support frame () configured to bear a heat exchanger comprising a flange () for coolant to pass through, the frame comprising a lateral wall () in which a light () is produced, which is configured to be passed through by the flange (), characterized in that the lateral wall () comprises at least one edge () placed near an end of the light () and arranged at least partially through the light () so as to define an insertion path for the flange which is inclined relative to the normal to the lateral wall, the edge also being configured to form a point on which the flange pivots.

Frame configured to support a heat exchanger

The invention relates to a sealing device () for a motor vehicle heat ex-changer () consisting of a plate () comprising a central cavity () configured to allow the passage of a tube of the heat exchanger, characterised in that at least two opposite end edges of said plate () are each provided with snap-fastening means (), each capable of engaging with complementary snap-fastening elements integrated into a recess located in a support frame of the heat exchanger, and characterised in that the sealing device () comprises an elastically deformable sealing means () arranged around the central cavity () formed in the plate ().

Sealing device for a motor vehicle heat exchanger

The invention relates to a collector plate () for a heat exchanger (), the collector plate () comprising: According to the invention, at the said at least one longitudinal end of the collector plate (), the said groove () has an inner wall (), at least one section of which connects the intermediate portion () to the bottom () of the said groove () and extends over a height (H) which is not zero and is less than the height (H) of the upper step (). The invention also relates to a corresponding header box () and a corresponding heat exchanger ().
