Abstract

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. 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 exhaust port, the refrigerant cooling branch, the fifth end, the sixth end and the suction port are communicated in sequence to form a direct heat circuit. According to the thermal management system of the present invention, not only the temperature regulation of the interior of the vehicle and the heat source device of the vehicle can be realized, but also the temperature regulation of the battery pack can be realized, so that the vehicle and the battery pack can be used in a more economical and energy-saving manner to meet the requirements of different working conditions. heating and cooling requirements under conditions.

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] During the charging and discharging 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 use 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 present invention aims to...
