The invention discloses a thermal management system for a vehicle and the vehicle. The thermal management system includes a compressor, a first indoor heat exchanger, a second indoor heat exchanger, an outdoor heat exchanger, a heat source device, and a battery pack. The battery pack includes a refrigerant cooling branch and a liquid cooling branch, and the refrigerant is adapted to flow in at least one of the compressor, the first indoor heat exchanger, the second indoor heat exchanger, and the outdoor heat exchanger to form a refrigerant circulation flow path. The liquid cooling circuit is adapted to exchange heat with the heat source device. The refrigerant cooling branch can be selectively communicated with the refrigerant circulation flow path, and the liquid-cooling cooling branch can be selectively communicated with the liquid-cooling circuit. The refrigerant cooling branch is optionally connected in parallel with the first indoor heat exchanger. According to the thermal management system of the present invention, not only can the temperature of the interior space of the vehicle and the heat source device be adjusted, but also the temperature of the battery pack can be adjusted, so that the vehicle and the battery pack under different working conditions can be met in a more economical and energy-saving manner. heating and cooling needs.
Description
technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a thermal management system of a vehicle and a vehicle. Background technique [0002] In order to improve the charging and discharging efficiency of the battery, it is necessary to have a suitable working temperature. Too high or too low will have a great impact on its performance and endurance. In the related art, the battery is cooled by setting an independent cooling channel. In addition, some vehicles combine the air conditioning system to control the temperature of the battery, and the air conditioning system is used to exchange heat for the cooling liquid flowing through the battery, so as to realize the cooling of the battery. or warming up. They all adopt the technology of battery liquid cooling, the structure is complex and the cooling efficiency is low, which cannot meet the temperature requirements of the battery. SUMMARY OF THE INVENTION [0003] The...
