Abstract

The invention discloses a heat management system, a control method thereof and a vehicle. The heat management system comprises a compressor, an outdoor heat exchanger, a gas-liquid separator and a heat management integrated unit. The heat management integrated unit is connected with the compressor and the outdoor heat exchanger, and the gas-liquid separator is connected to an inlet of the compressor. The heat management integrated unit comprises a runner plate, a water cooling condenser and a first throttling device. The heat management system has a first working mode, in the first working mode, the compressor is started, the first throttling device is in a fully-opened state, and a refrigerant flows through the water-cooled condenser under the action of the compressor and then enters the outdoor heat exchanger from the first throttling device to be cooled so as to deice the outdoor heat exchanger; and the cooled refrigerant flows through the gas-liquid separator and then enters the compressor. In this way, high-temperature and high-pressure refrigerants flowing out of the compressor can be used for efficiently deicing the outdoor heat exchanger.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and more specifically, to a thermal management system, a control method thereof, and a vehicle. Background technique [0002] In related technologies, when the ambient humidity is high, when the vehicle uses the heat pump system to heat the battery or the passenger compartment for a long time, it is easy to cause the outdoor heat exchanger to defrost and freeze, resulting in insufficient heating capacity. . Therefore, how to effectively de-ice the outdoor heat exchanger has become a technical problem studied by technicians. Contents of the invention [0003] Embodiments of the present invention provide a thermal management system, a control method thereof, and a vehicle. [0004] The thermal management system according to the embodiment of the present invention is used for a vehicle, and the thermal management system includes a compressor, an outdoor heat exchanger, a gas-liquid sepa...
