A thermal management system, at least comprising a refrigerant system, wherein the refrigerant system comprises: a compressor (10), a flow control device (15), a valve member (16), a first heat exchanger (11), a second heat exchanger (12), and a third heat exchanger (13). The flow control device (15) comprises a first throttle unit (151), a second throttle unit (152), and a valve assembly; the flow control device (15) comprises a first port (1501), a second port (1502), and a third port (1503); a first connection port of the first heat exchanger (11) is in communication with the second port (1502), and a first connection port of the second heat exchanger (12) is in communication with the third port (1503), while a first connection port of the third heat exchanger (13) is in communication with the first port (1501). The thermal management system comprises a first operating state and a second operating state; in the first operating state, refrigerant flows into the first port (1501) of the flow control device (15) from the first connection port of the third heat exchanger (13); in the second operating state, refrigerant flows into the second port (1502) of the flow control device (15) from the first connection port of the first heat exchanger (11); in the first operating state and the second operating state, refrigerant may flow out of the flow control device (15) from the third port (1503). The three ports (1501, 1502, 1503) of the flow control device (15) of the thermal management system are connected to the three heat exchangers (11, 12, 13) by means of the described manner of connection, which facilitates the simplification of the thermal management system are connected to the three heat exchangers (11, 12, 13) by means of the described manner of connection, which facilitates the simplification of the thermal management system.
