A heat exchanger for performing heat exchange of a medium by heat conducted to tubes (210) and fins (220), the heat exchanger is configured by assembling the tubes, the fins, tanks (300) and a connector (400) and heating them in a furnace to be brazed into one body, wherein the connector is made of aluminum or its alloy and has a seating face to be brazed to the outer surface of the tank, and when it is determined that the connector has a surface area of X Äcm<2>Ü and a volume of Y Äcm<3>Ü, they have a relation of X>/=1.5 . (36 pi Y<2>)<1/3>, Y</=30. <IMAGE> |
