<p>The present invention relates to a heat exchanger. According to the present invention, a heat transfer tube is connected at a predetermined angle with respect to the width direction of a header pipe and an extension rib, and a ventilation guide hole is formed so that interference with the heat transfer tube is minimized when a refrigerant moves within the header pipe and the the refrigerant can travel smoothly within the header pipe. Also, the gaps between heat transfer pins can be conveniently aligned so as to be uniform, and the contact area and contact time between the heat transfer pins and the tube are increased in order to improve heat transfer efficiency.</p> |
