Abstract

Support frame (4) configured to bear a heat exchanger comprising a flange (22) for coolant to pass through, the frame comprising a lateral wall (12) in which a light (28) is produced, which is configured to be passed through by the flange (22), characterized in that the lateral wall (12) comprises at least one edge (34, 36) placed near an end of the light (28) and arranged at least partially through the light (28) 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.

First claim

The invention claimed is:

1. A support frame configured to bear a heat exchanger comprising a flange for passage of coolant fluid, the frame comprising:
a side wall in which a slot is produced for the flange to pass through,
wherein the side wall comprises a first rim placed near an end of the slot and disposed at least partially in the slot so as to define an insertion path for the flange which is inclined relative to the normal to the side wall, said first rim also being configured to form a pivot point for the flange, and
wherein the first rim comprises:
a first protruding portion that protrudes substantially perpendicularly to the side wall delimiting the slot in a first direction;
a first return portion that extends to reduce a passage cross-section of the slot; and
a second return portion that forms a free end of the first rim and extends perpendicular to the first return portion so as to form a staircase profile of the first rim to reduce the passage cross-section of the slot,

wherein the support frame comprises a second rim comprising a second protruding portion that protrudes substantially parallel to the side wall delimiting the slot in a second direction perpendicular to the first direction,
wherein the second rim comprises:
a first portion; and
a return edge that forms a free end of the second rim and extends perpendicular to the first portion of the second rim so as to reduce the passage cross-section of the slot and form a staircase profile of the second rim,
wherein the first and second rims delimit opposing ends of the slot, and

wherein the first rim and the second rim define the insertion path such that the flange must be inclined relative to the normal to the side wall in order to be inserted in the slot.

2. The support frame as claimed in claim 1 , wherein the rims each have a proximal end linked to the side wall and a free distal end, the free distal end of each rim being configured to bear on a surface of the flange when the latter is placed in the support frame.

3. The support frame as claimed in claim 1 , wherein the rims each have a bent form extending in a longitudinal projection from the side wall in opposite directions along the normal to said side wall.

4. The support frame as claimed in claim 2 , wherein the free distal end of the rim extending in a longitudinal projection from the side wall towards the interior of the frame is configured to serve as a support face for the flange in order to form said pivot point in the slot.

5. The support frame as claimed in claim 2 , wherein the rims are configured in a bent portion such that their distal end is closer to the centre of the slot than their proximal end.

6. The support frame as claimed in claim 2 , wherein the minimal dimension between two crests of the distal ends of the two rims is greater than the dimension between these two crests in a projection plane congruent with the plane of extension of the side wall.

7. A method for assembly of a heat exchanger with an inlet/outlet flange for coolant fluid in a support frame defined as claimed in claim 1 , the method comprising:
insertion of the flange in the slot made in a side wall of the support frame, with an insertion position in a plane which has an angle of inclination between 10° and 80° relative to the plane in which the heat exchanger is positioned at the end of assembly,
wherein the insertion brings the flange at an angle through the slot while avoiding the first and second rims; and
pivoting the flange in the slot in order to give the heat exchanger its final assembly position which is substantially perpendicular to the side wall.

8. A front end module comprising:
a support frame comprising a side wall in which a slot is produced for a flange to pass through,
wherein the side wall comprises a first rim placed near an end of the slot and disposed at least partially in the slot so as to define an insertion path for the flange which is inclined relative to the normal to the side wall, said first rim also being configured to form a pivot point for the flange,
wherein the first rim comprises:
a first protruding portion that protrudes substantially perpendicularly to the side wall delimiting the slot in a first direction;
a first return portion that extends to reduce a passage cross-section of the slot; and
a second return portion that forms a free end of the first rim and extends perpendicular to the first return portion so as to form a staircase profile of the first rim to reduce the passage cross-section of the slot,

wherein the support frame comprises a second rim comprising a second protruding portion that protrudes substantially parallel to the side wall delimiting the slot in a second direction perpendicular to the first direction,
wherein the second rim comprises:
a first portion; and
a return edge that forms a free end of the second rim and extends perpendicular to the first portion of the second rim so as to reduce the passage cross-section of the slot and form a staircase profile of the second rim,
wherein the first and second rims delimit opposing ends of the slot,

wherein at least one heat exchanger bearing a flange for inlet or outlet of coolant fluid, said flange bearing against at least one support face formed by the first and second rims of said support frame, and
wherein the first rim and the second rim define the insertion path such that the flange must be inclined relative to the normal to the side wall in order to be inserted in the slot.

9. The front end module as claimed in claim 8 , wherein at its free end, the flange comprises at least one edging configured to come to rest against the first rim of the support frame.
