Abstract

A clip includes a body defining an exterior profile, and an adjustably sized aperture. The exterior profile defines at least one attachment feature and the body includes a surface defining the adjustably sized aperture and at least one stop member disposed in the adjustably sized aperture.

First claim

What is claimed is:

1. A heat exchanger assembly comprising:
a heat exchanger including
a first tube member defining a perimeter and an axis of extension, an axial direction extending parallel to the axis of extension; and
a fin comprising
a first undulating fin section disposed adjacent to the first tube member,
a second undulating fin section disposed adjacent to the first tube member and being spaced away from the first undulating fin section along the axial direction, defining an axial gap therebetween, and
a first straight section connecting the first undulating fin section to the second undulating fin section; and

a clip disposed in the axial gap and at least partially encompassing the perimeter of the first tube member,
the clip defining an aperture and the first tube member extending axially through the aperture, such that the clip at least partially encompasses the first straight section,
wherein the first straight section defines a first top edge and the clip further includes a first projection disposed in the aperture of the clip adjacent to the first top edge.

2. The heat exchanger assembly of claim 1 wherein the first straight section is attached to the perimeter of the first tube member and extends axially along the perimeter of the first tube member.

3. The heat exchanger assembly of claim 2 wherein the clip completely encompasses the perimeter of the first tube member.

4. The heat exchanger assembly of claim 1 wherein the first straight section defines a first bottom edge disposed opposite the first top edge and the clip further includes a second projection disposed in the aperture of the clip adjacent to the first bottom edge.

5. The heat exchanger assembly of claim 1 wherein the first straight section is brazed to the first tube member and the first tube member includes an annular configuration including a first straight side, a second straight side, a first arcuate portion connecting the first straight side to the second straight side, and a second arcuate portion connecting the first straight side to the second straight side.

6. The heat exchanger assembly of claim 5 wherein the first straight side is parallel to the second straight side, the first arcuate portion is disposed diametrically opposite of the second arcuate portion, and the first straight section contacts the first straight side, forming a first double wall.

7. The heat exchanger assembly of claim 1 wherein the first tube member and the fin comprise a same material.

8. The heat exchanger assembly of claim 7 wherein the same material includes one of the following: aluminum and copper.

9. The heat exchanger assembly of claim 1 wherein the clip comprises
a body defining an exterior profile; and
an adjustably-sized aperture,
wherein the exterior profile defines at least one attachment feature, and the body includes a surface defining the adjustably-sized aperture and at least one stop member disposed in the adjustably-sized aperture.

10. The heat exchanger assembly of claim 9 wherein the body defines a living hinge disposed adjacent to the exterior profile and forming a portion of the adjustably-sized aperture, and a seam connecting the exterior profile to the adjustably-sized aperture.

11. The heat exchanger assembly of claim 9 wherein the at least one attachment feature includes at least one of the following: a tenon and a mortise.

12. The heat exchanger assembly of claim 9 wherein the seam defines an undercut configured to keep the body locked in a closed configuration to minimize the size of the adjustably-sized aperture.

13. The heat exchanger assembly of claim 9 wherein the exterior profile includes a quadrilateral shape with four sides, and each of the four sides includes the at least one attachment feature.
