Abstract
The present disclosure discloses a heat exchanger and an air conditioning system having the heat exchanger. The heat exchanger includes a first heat exchanger core, a second heat exchanger core and a connection part. Heat exchange tubes of the first heat exchanger core and the second heat exchanger core include first circuit heat exchange tubes. A length of the heat exchange tube of the first heat exchanger core is greater than a length of the heat exchange tube of the second heat exchanger core. The connection part includes a first connection part through which the first circuit heat exchange tubes of the first heat exchanger core are connected with the first circuit heat exchange tubes of the second heat exchanger core. The heat exchange tubes of at least one of the first heat exchanger core and the second heat exchanger core further include second circuit heat exchange tubes. First circuit heat exchange tube groups each constituted by at least one of the first circuit heat exchange tubes and second circuit heat exchange tube groups each constituted by at least one of the second circuit heat exchange tubes are arranged alternately. Thereby, the heat exchange performance can be improved at both partial load and full load.
