Patent-family-91386035

The utility model discloses a heat exchanger and an air conditioning system with 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-shape or an inverted V-shape. The first heat exchanger unit comprises a first heat exchanger core section and a second heat exchanger core section which are arranged side by side and provided with heat exchange pipes and fins, and the size of the first heat exchanger core section of the first heat exchanger unit is larger than or equal to that of the second heat exchanger core section of the first heat exchanger unit. The second heat exchanger unit comprises a first heat exchanger core section, a second heat exchanger core section and a third heat exchanger core section which are arranged side by side and provided with heat exchange pipes and fins, and the size of the first heat exchanger core section and the size of the third heat exchanger core section of the second heat exchanger unit are smaller than or equal to the size of the second heat exchanger core section of the second heat exchanger unit. By adopting the heat exchanger, the heat exchange performance can be improved.
