Abstract: A heat exchange assembly and an air conditioning system having the same. The heat exchange assembly includes a heat exchanger and a water guide device. The heat exchanger includes a first heat exchanger core and a second heat exchanger core. The first heat exchanger core includes a plurality of first heat exchange tubes, the second heat exchanger core is located on one side of the first heat exchanger core in a thickness direction of the first heat exchanger core and comprises a plurality of second heat exchange tubes, and a lower edge of the second heat exchanger core is higher than a lower edge of the first heat exchanger core. The water guide device includes a first water guide device, wherein at least part of the first water guide device is arranged below the second heat exchanger core and used for receiving and guiding condensed water from the second heat exchanger core. The heat exchange assembly and the air conditioning system according to the present disclosure reduce the risk of the condensed water being blown out of the heat exchanger core with a higher lower edge.

Abstract: A heat exchanger and an air conditioning system having the same. The heat exchanger includes at least one of a first heat exchanger unit and a second heat exchanger unit, and the heat exchanger has a V-shaped or inverted V-shaped shape. The first heat exchanger unit includes a first heat exchanger core segment and a second heat exchanger core segment, which are arranged side by side and each have heat exchange tube(s) and fin(s). A size of the first heat exchanger core segment of the first heat exchanger unit is larger than or equal to that of the second heat exchanger core segment of the first heat exchanger unit. The second heat exchanger unit includes a first heat exchanger core segment, a second heat exchanger core segment and a third heat exchanger core segment each having heat exchange tube(s) and fin(s), the first heat exchanger core segment and the third heat exchanger core segment being arranged side by side with the second heat exchanger core segment in a first direction of the second heat exchanger unit, respectively. A size of the first heat exchanger core segment and a size of the third heat exchanger core segment of the second heat exchanger unit are smaller than or equal to that of the second heat exchanger core segment of the second heat exchanger unit, respectively. With the heat exchanger according to the present invention, the heat exchange performance can be improved.
