Problems solved by technology

When the traditional air-conditioning system is used to cool the vehicle-mounted refrigerator, since the core component of the refrigeration is a mechanical compressor, the power system output of the vehicle will be lost when the refrigerator is rapidly refrigerated, affecting the driving experience of the user; in addition, if the vehicle’s air-conditioning system is not turned on, only Turning on the air conditioning system due to the cooling of the car refrigerator will cause waste of energy consumption and loud noise

Embodiment approach

[0095] Refrigerator bypass and air conditioning system can operate independently of each other, as another alternative fourth embodiment, such as Figure 8 As shown, the automobile thermal management system also includes a first flow valve 631 and a second flow valve 632, the first flow valve 631 is arranged at the outlet end of the first throttling branch and the first flow branch and the outdoor heat exchanger of the air conditioner Between the inlet of 605 , the second flow valve 632 is arranged between the outlet of the first throttling branch and the first flow branch and the inlet of the refrigerator evaporator 623 . In addition, the first flow valve 631 and the second flow valve 632 can also adjust the flow of the branches where they are located.

[0096] Further, in order to prevent the low-temperature and low-pressure refrigerant flowing out from the outlet of the first expansion valve 622 from flowing to the condenser 601 in the air-conditioning room in the extreme c...

Abstract

The invention relates to an automotive thermal management system and an electric vehicle. The system includes a heat pump air-conditioner system and a vehicle-mounted refrigerator system, the heat pump air-conditioner system includes an air-conditioner compressor, an air-conditioner indoor condenser, an air-conditioner indoor evaporator and an air-conditioner outdoor heat exchanger, the outlet ofthe air-conditioner indoor condenser is also communicated with the inlet of a refrigerator evaporator through a second expansion valve, and the outlet of the refrigerator evaporator is also communicated with the inlet of the air-conditioner indoor evaporator or the inlet of the air-conditioner compressor. Therefore, when a bypass heating refrigerator is in a bypass refrigeration mode, the refrigerator evaporator can replace the air-conditioner outdoor heat exchanger, the waste heat generated by the refrigeration of a refrigerator can be used for heating the refrigerant of an air-conditioner system, and simultaneously refrigerator cooling and air-conditioner heating are achieved based on an energy-saving mode.

Description

technical field [0001] The present disclosure relates to the field of car refrigerators of electric vehicles, and in particular, relates to a thermal management system of a vehicle and an electric vehicle. Background technique [0002] The car refrigerator is a refrigerated cabinet carried on the car, and it is a new generation of refrigerated appliances popular in the international market. In the related art, when an independent micro compressor is used to cool the vehicle-mounted refrigerator, the cooling power is small and the cooling speed is slow. When the traditional air-conditioning system is used to cool the vehicle-mounted refrigerator, since the core component of the refrigeration is a mechanical compressor, the power system output of the vehicle will be lost when the refrigerator is rapidly refrigerated, affecting the driving experience of the user; in addition, if the vehicle’s air-conditioning system is not turned on, only Turning on the air conditioning system...
