Abstract

The invention provides a heat management system of a vehicle and the vehicle. The heat management system comprises an air conditioning system, a PTC heating system and a heat dissipation system, wherein the air conditioning system comprises a compressor, an outdoor heat exchanger, a first throttling element, an evaporator and a water chilling unit; the compressor, the outdoor heat exchanger, the first throttling element and the evaporator are sequentially connected end to end; the evaporator is connected with the water chilling unit in parallel; and the water chilling unit further communicateswith a battery pack pipeline at a battery pack; the PTC heating system corresponds to a warm air core pipeline at a warm air core and the battery pack pipeline at the battery pack; and the heat dissipation system corresponds to a high-voltage system pipeline at a high-voltage system, a drive motor pipeline at a drive motor and the battery pack pipeline at the battery pack. The heat management system can reasonably control the temperatures of a cockpit, the battery pack, the high-voltage system and the drive motor, so that the temperature control of the whole vehicle is reasonable, integratedcontrol is achieved, and the purpose of accurate and intelligent cooling system design can 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] The design and thermal management of the cooling system of existing new energy vehicles are relatively extensive. There is no refined and intelligent control design for the battery cooling method, and some even do not use any cooling and heating methods. Although some fans are added inside the closed battery pack to circulate the internal air and balance the internal temperature field, the effect is negligible, resulting in overcooling or overheating of the battery pack, which affects the capacity, safety and life of the battery pack. [0003] The active air-cooled thermal management method has high requirements for the design of the internal air duct of the battery pack, and the air heat exchange efficiency is low, the cooling and heating speed is slow, and the internal temperature uniformit...
