<p>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving durability of a tube without increasing flow passage resistance of a refrigerant.SOLUTION: A heat exchanger 1 includes: a pair of tanks 3, 3 in which a refrigerant flows; a plurality of tubes 7 in which both end parts 5, 5 communicate with the pair of tanks 3, 3; and a refrigerant introduction port 9 which is provided at one end in the longitudinal direction of one of the tanks 3 and which introduces the refrigerant to the one tank 3. At an end part in the longitudinal direction of the one tank 3, an inclined part 15 is provided which inclines so as to expand its diameter toward the piping side which allows the refrigerant to flow into the one tank 3. An end part 5 of the tube 7 which communicates with the one tank located on the refrigerant introduction port 9 side is located on a further outer peripheral side in the refrigerant flow than an extension line L toward an inner side of the one tank 3 from the inclined part 15.</p> |
