Abstract: Provided is a tube for a heat exchanger, and more particularly, a tube for a heat exchanger forming a channel of a heat exchange medium and including a plurality of inner holes having inner spaces separated in a width direction by a plurality of inner walls extending in a longitudinal direction, in which a thickness of outer walls of certain regions at both ends in the width direction of the tube is formed to be thicker than that of the remaining regions, thereby improving heat exchange performance and preventing corrosion.

Abstract: A heat exchanger having an optimum design considering a thermal capacity of an end portion of an extrusion tube to significantly improve heat transfer performance by optimizing a shape and a thickness of the end portion of the tube, and a heat exchanger having an optimum design obtained based on a structured rule to enable easy application to other tubes with various dimensions. The heat exchanger has an end portion of a tube has a cross section in a quadrangular shape with rounded corners, each having a radius in a range of 15% to 45% of a height of the tube.
