Abstract
A heat exchange tube () for a heat exchanger, heat exchanger and assembly method thereof. The heat exchange tube () is a combined heat exchange tube having a space () at its center, and the space () is configured to accommodate an insertion member (), such that the combined heat exchange tube is expanded in and joined with a corresponding fin hole () 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.
