Heat exchanger and air-conditioning system

Abstract

Embodiments of the present application disclose a heat exchanger and an air-conditioning system. The heat exchanger includes heat exchange tubes. The heat exchange tubes include first heat exchange tubes configured to form a first circuit, and second heat exchange tubes configured to form a second circuit. With the heat exchanger according to the embodiments of the present application, if one of two circuits of a two-circuit air-conditioning system is turned off, a heat exchange efficiency of the heat exchanger can be improved.
