Abstract: A heat pump system includes a compressor, a fluid switching device, a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a flow regulating device and a throttle element. The second heat exchanger includes a first heat exchange portion and a second heat exchange portion. An outlet of the first heat exchange portion communicates with the throttle element. An inlet of the first heat exchange portion communicates with at least one of a second port of the third heat exchanger and an outlet of the fourth heat exchanger. An inlet of the second heat exchange portion communicates with the outlet of the first heat exchanger. An outlet of the second heat exchange portion communicates with an inlet of the compressor.

Abstract: A thermal management system includes a cooling liquid circulation flow path, a refrigerant circulation flow path and a first heat exchanger. The first heat exchanger includes a first heat exchange portion and a second heat exchange portion. The cooling liquid circulation flow path includes a first heat exchange assembly, a second heat exchange assembly and a first branch. The thermal management system has a heating mode. After passing through the first heat exchange assembly, one path of the cooling liquid flows to the first branch, and another path of the cooling liquid flows to the second heat exchange assembly. The cooling liquid after flowing through the first branch and after flowing through the second heat exchange assembly merge and then flow to the first heat exchange portion. As a result, the number of heat exchangers used by the thermal management system to recover waste heat is reduced.
