An alignment apparatus is capable of suppressing widening of legs of hairpin-shaped heat-exchanger tubes and aligning the hairpin-shaped heat-exchanger tubes in the horizontal direction at a regular pitch. The alignment apparatus includes: a plurality of outer guide plates that have rollers, which contact upstream sides of legs of the hairpin-shaped heat-exchanger tubes that have been stopped by a stopper apparatus, and that contact outer side surfaces of the legs; a horizontal movement apparatus that moves the outer guide plates in a horizontal direction; an up-down movement apparatus that moves the outer guide plates in an up-down direction; and a control unit that drives the horizontal movement apparatus to move the outer guide plates a predetermined distance toward an insertion position, and then drives the up-down movement apparatus to raise the outer guide plates by a predetermined distance to change an orientation of the hairpin-shaped heat-exchanger tubes to the horizontal direction.

Various methods and systems are provided for an exhaust gas recirculation cooler including a plurality of cooling tubes. In one example, an exhaust gas recirculation (EGR) cooler includes a plurality of cooling tubes positioned within a housing of the EGR cooler, each cooling tube of the plurality of cooling tubes extending between and directly coupled to tube sheets of the EGR cooler at ends of each cooling tube, where at least one end of one or more cooling tubes of a first portion of the plurality of cooling tubes, inward of a tube sheet coupled to the at least one end, includes a compliant region, where the first portion is positioned proximate to an exhaust inlet of the EGR cooler.

A heat exchange tube (51) for a heat exchanger, heat exchanger and assembly method thereof. The heat exchange tube (51) is a combined heat exchange tube having a space (55) at its center, and the space (55) is configured to accommodate an insertion member (57), such that the combined heat exchange tube is expanded in and joined with a corresponding fin hole (53) in the heat exchanger. A heat exchange tube that is minute or has a small inner diameter can thus be expanded in a heat exchanger fin without employing a brazing process.
