1. An apparatus for bending a heat exchanger, wherein the apparatus comprises:
a plurality of support rollers, wherein the plurality of support rollers are arranged to be spaced apart in a longitudinal direction, each of the support rollers comprises a first support surface and a second support surface that are spaced apart in a transverse direction and that are configured to abut against the heat exchanger, a distance between the first support surface and the second support surface keeps unchanged during the heat exchanger bending process, and a distance between the first support surface and the second support surface of one support roller of any two of the plurality of support rollers is equal to a distance between the first support surface and the second support surface of the other support roller of the two support rollers; and
a connecting component, wherein the connecting component connects the plurality of support rollers in the longitudinal direction, wherein the connecting component is a rectangular connecting frame and comprises two longitudinal rods parallel to each other and two transverse rods parallel to each other; the two longitudinal rods extend in the longitudinal direction, and the two transverse rods extend in an axial direction of the support rollers; and one transverse rod of each rectangular connecting frame passes through one of two adjacent support rollers of the plurality of support rollers in the axial direction of the support roller, and the other transverse rod passes through the other of the two adjacent support rollers in the axial direction of the support roller.
