Patent ID: 7637309

Claim:
A cooling module (I), comprising a first heat exchanger ( 3 ) having a first heat exchange core ( 12 ), which is placed between and communicates with a first pair of parallel supporting manifolds ( 10 , 11 ), and a second heat exchanger ( 4 ) having a second heat exchange core ( 9 ), which is in back-to-front relationship with said first heat exchange core ( 12 ) and which is placed between and communicates with a second pair of parallel supporting manifolds ( 7 , 8 ) perpendicular to said first pair of supporting manifolds ( 10 , 11 ), wherein said first pair of supporting manifolds ( 10 , 11 ) is directly interconnected with said second pair of supporting manifolds ( 7 , 8 ) at four heat exchanger corners ( 13 , 14 , 15 , 16 ) by means of fasteners, the first one ( 13 ) of said corners being located at a first end of a first manifold ( 10 ) of said pair of first supporting manifolds ( 10 , 11 ), the second one ( 14 ) of said corners being located at a second end of said first manifold ( 10 ), the third one ( 15 ) of said corners being located at a first end of a second manifold ( 11 ) of said pair of first supporting manifolds ( 10 , 11 ), and the fourth one ( 16 ) of said corners being located at a second end of said second manifold ( 11 ) and being diametrically opposed to the first corner ( 13 ), wherein one of said pairs of supporting manifolds ( 7 , 8 ; 10 , 11 ) is adapted to support the cooling module ( 1 ) on a motor vehicle frame ( 2 ), wherein a rigid fastener ( 19 ) is provided at said first corner ( 13 ) forcing the heat exchangers ( 3 , 4 ) always to swing in phase, a first two-way fastener ( 20 ) is provided at said second corner ( 14 ) allowing, for thermal compensation, mutual movement of the heat exchangers ( 3 , 4 ) at said second corner ( 14 ) only to and fro said rigid fastener ( 19 ), a second two-way fastener ( 22 ) is provided at said third corner ( 15 ) allowing, for thermal compensation, mutual movement of the heat exchangers ( 3 , 4 ) at said third corner ( 15 ) only to and fro said rigid fastener ( 19 ), and a four-way fastener ( 27 ) is provided at said fourth corner ( 16 ) allowing, for thermal compensation, mutual movement of the heat exchangers ( 3 , 4 ) at said fourth corner ( 16 ) to and fro said first two-way fastener ( 20 ) and said second two-way fastener ( 22 ).
