Abstract

The invention provides a vehicle and a thermal management system thereof, and relates to the field of vehicles. The technical problem that an air conditioning system and a power source cooling systemof an existing vehicle are not related to each other or have insufficient correlation is solved. According the adopted scheme, the thermal management system of the vehicle comprises a heat pump air conditioning circuit, a power source cooling circuit and an intermediate heat exchanger; the power source cooling circuit is used for dissipating heat of a motor system of the vehicle or recycling the heat of the motor system; and the heat pump air conditioning circuit exchanges heat with the power source cooling circuit through the intermediate heat exchanger so as to exchange heat between a refrigerant in the heat pump air conditioning circuit and cooling medium of the power source cooling circuit. According to the technical scheme, the heat in the system can be distributed regardless of whether the vehicle runs or charges, integrated heat management of a power source device and an air conditioning system is realized, high temperature waste heat generated by a motor under high load is effectively recycled, use of the waste heat is realized, and the efficiency of the heat pump air conditioning system is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle and its thermal management system. Background technique [0002] In order to avoid excessive heating of the electric motor under extreme conditions such as frequent braking and climbing, which will cause overheating damage to the motor, it is necessary to dissipate heat from the power source and transfer the heat energy of the vehicle air conditioner. Therefore, how to manage the heat distribution of electric buses is currently One of the research directions of new energy vehicles. [0003] At this stage, there is no application case of comprehensive thermal management in the field of passenger cars, and the energy-saving performance of the thermal management system is not significant enough. The thermal management of conventional passenger cars adopts a decentralized and independent thermal management system, and the key components of the battery and motor have th...
