Abstract
A heat exchanger assembly includes a first heat exchanger having a pair of mounts attached to one of the tanks of the first heat exchanger and a second heat exchanger having a pair of brackets attached to one of the tanks of the second heat exchanger. The brackets are freely insertable into the mounts when the two heat exchangers are at an acute angle with respect to each other. When the two heat exchangers are parallel with each other, an interference condition exists between the brackets and the mounts. The opposite side of the heat exchangers is secured using a retainer on one heat exchanger extending through a strap on the other heat exchanger.
Claims19
A heat exchanger assembly comprising:
- a first heat exchanger;
- a mount attached to said first heat exchanger;
- a second heat exchanger;
- a bracket attached to said second heat exchanger, said bracket engaging said mount to attach said second heat exchanger to said first heat exchanger;
- wherein
- said bracket is freely inserted into said mount when said second heat exchanger is at an acute angle with respect to said first heat exchanger, said bracket having an interference fit with said mount when said second heat exchanger is parallel with said first heat exchanger,
- wherein said mount comprises:
- a first upright extending from said first heat exchanger in a height direction of said mount;
- a second upright extending from said first heat exchanger in the height direction;
- a lower retaining wall extending between said first and second uprights in a length direction of said mount generally perpendicular to the height direction;
- and
- an upper retaining wall extending between said first and second uprights in the length direction;
- wherein
- a gap in a width direction of said mount is defined between said lower retaining wall and said upper retaining wall, the width direction being generally perpendicular to both the height direction and the length direction,
- an opening in the height direction of said first and second uprights is defined between said lower retaining wall and said upper retaining wall,
- the upper retaining wall is immovably fixed to the first and the second upright to keep the gap and the opening relative to the lower retaining wall,
- there is no overlap between the lower retaining wall and the upper retaining wall in the width direction of the mount,
- there is no overlap between the lower retaining wall and the upper retaining wall in the height direction of the mount, and wherein
- said mount further comprises an insertion slot defined by the gap and the opening, which accepts the bracket by tilting the second heat exchanger at the acute angle with respect to the first heat exchanger, and
- the second heat exchanger is moved into its installed position parallel with the first heat exchanger to create the interference fit between the bracket and the mount.

- a pair of brackets attached to said third tank, each of said brackets being freely inserted into a respective mount when said second heat exchanger is at an acute angle with respect to said first heat exchanger, each of said brackets having an interference fit with said respective mount when said second heat exchanger is parallel with said first heat exchanger,
- wherein each of said mounts comprises:
- a first upright extending from said first tank in a height direction of the mount;
- a second upright extending from said first tank in the height direction;
- a lower retaining wall extending between said first and second uprights in a length direction of the mount generally perpendicular to the height direction;
- and

- an opening in the height direction of said first and second uprights is defined between said lower retaining wall and said upper retaining wall,
- the upper retaining wall is immovably fixed to the first and the second upright to keep the gap and the opening relative to the lower retaining wall,
- there is no overlap between the lower retaining wall and the upper retaining wall in the width direction of the mount,
- there is no overlap between the lower retaining wall and the upper retaining wall in the height direction of the mount, and
- wherein
- each of said mounts further comprises an insertion slot defined by the gap and the opening, which accepts the bracket by tilting the second heat exchanger at the acute angle with respect to the first heat exchanger, and
- the second heat exchanger is moved into its installed position parallel with the first heat exchanger to create the interference fit between the bracket and the mount.
