Abstract
A heat exchanger and an air conditioning unit with multiple refrigeration systems. The heat exchanger includes a first header, a second header, a third header, a fourth header, a heat exchange tube including a first heat exchange tube and a second heat exchange tube alternately arranged in a length direction of the header, and fins. The first heat exchange tube or the second heat exchange tube or both has a bent section and includes a first section, a middle section, and a second section, and the heat exchanger includes a first part including the first section, a middle part, and a second part. The middle part of the heat exchanger includes the middle section and the fins, and air flowing through the heat exchanger passes through the middle part and then the first part, or passes through the first part and then the middle part.
