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.
