1. A method of manufacturing a heat exchanger, the method comprising:
providing a first slab comprising a first plurality of tubes extending through a first plurality of fins, wherein the first plurality of tubes extends from a first end to a second end of the first slab along a first length of the first slab, wherein the first slab comprises a first face that extends along the first length between the first end and the second end;
providing a second slab comprising a second plurality of tubes extending through a second plurality of fins, wherein the second plurality of tubes extends from a third end to a fourth end of the second slab along a second length of the second slab, wherein the second length of the second slab is different than the first length of the first slab, and the second slab comprises a second face that extends along the second length between the third end and the fourth end;
positioning the first face of the first slab adjacent to the second face of the second slab in a side-by-side configuration, wherein, in the side-by-side configuration, the first end of the first slab is aligned with the third end of the second slab along a lateral axis extending cross-wise to the first length and the second length;
securing a connector to the first end of the first slab and to the third end of the second slab in the side-by-side configuration; and
after securing the connector to the first end of the first slab and to the third end of the second slab, bending the first slab and the second slab together in the side-by-side configuration to form a bent configuration of the heat exchanger, wherein the second end of the first slab and the fourth end of the second slab are aligned with one another in the bent configuration.
