Abstract

The invention discloses a heat management system of a vehicle and the vehicle. The heat management system comprises a compressor, a first indoor heat exchanger, a second indoor heat exchanger, an outdoor heat exchanger, a reversing valve, a motor and a battery pack. The battery pack comprises a refrigerant cooling branch and a liquid cooling branch, and a refrigerant is suitable for flowing in atleast one of the compressor, the first indoor heat exchanger, the second indoor heat exchanger and the outdoor heat exchanger to form a refrigerant circulating flow path. The refrigerant circulation flow path comprises a refrigeration loop and a heating loop. The liquid cooling loop is suitable for exchanging heat with the motor. The refrigerant cooling branch is selectively communicated with therefrigerant circulating flow path, and the liquid cooling branch is selectively communicated with the liquid cooling loop. The refrigerant cooling branch is selectively connected between the first indoor heat exchanger and the outdoor heat exchanger in series. According to the heat management system, temperature adjustment of the interior of the vehicle and the motor of the vehicle can be achieved, and temperature adjustment of the battery pack can also be achieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a thermal management system of a vehicle and the 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 battery life. In the related technology, the temperature of the battery is cooled by setting an independent cooling port. In addition, some vehicles combine the air conditioning system to control the temperature of the battery, and the air conditioning system exchanges heat for the coolant flowing through the battery to achieve cooling of the battery. or heat up. They all adopt battery liquid cooling technology, which has a complex structure and low cooling efficiency, which cannot meet the temperature requirements of the battery. Contents of the invention [0003] The present invention aims ...
