Abstract: A heat exchanger for a CO2 refrigerant includes at least three rows of tube groups including a plurality of tubes having an independent refrigerant path, first and second header pipes including a header where a plurality of tube insertion holes into which the tubes are inserted are formed and a tank having partition walls formed along a direction of the flow of a refrigerant, wherein a plurality of return holes are formed in the partition walls, end caps sealing both end portions of the firs and second header pipes, a coupling reinforcement portion installed at least one of the first and second header pipes and reinforcing a coupling force of the header and the tank, a refrigerant inlet pipe connected to the first or second header pipe through which the refrigerant enters, and a refrigerant outlet pipe connected to the first or second header pipe through which the refrigerant is exhausted. The refrigerant entering through the refrigerant inlet pipe is made to flow in a direction adverse to a direction in which air flows.
