Problems solved by technology

Under low temperature conditions, turning on the air conditioner to heat the passenger compartment will consume a lot of power, resulting in a continuous decline in cruising range
[0003] In order to solve the problems of increased energy consumption and attenuation of mileage at low temperatures, heat pump technology has been gradually promoted in new energy vehicles. However, under the ultra-low temperature condition of -30°C, the existing heat pump technology is often unable to meet the needs of the passenger compartment or power battery heating. need

Abstract

The invention discloses a thermal management system and a vehicle. The heat management system has a first working mode, and in the first working mode, the valve assembly is in a first preset state so that the first cooling liquid output end of the water-water heat exchanger can communicate with an inlet of the battery water pump, and an inlet of the heating water pump can communicate with the cooling liquid output end of the battery cooler; and the outlet of the warm air core body and the second cooling output end of the water-water heat exchanger are communicated with the cooling liquid input end of the battery cooler at the same time. A refrigerant flows through the water-cooling condenser to heat the cooling liquid flowing through the water-cooling condenser, and the refrigerant flowing through the water-cooling condenser flows into the battery cooler; one part of the heated cooling liquid flows into the water-water heat exchanger to heat the power battery, the other part of the heated cooling liquid flows into the warm air core to heat a passenger compartment of the vehicle, and then all the cooling liquid converges and flows into the battery cooler to transfer heat to a refrigerant flowing through the battery cooler.

Description

technical field [0001] The present application relates to the technical field of vehicles, and more specifically, to a thermal management system and a vehicle. Background technique [0002] At present, with the continuous increase in the market share of new energy vehicles, how to reduce energy consumption and improve passenger comfort, the requirements for vehicle thermal management are getting higher and higher. Under low temperature conditions, turning on the air conditioner to heat the passenger compartment will consume a lot of power, resulting in a continuous decline in cruising range. [0003] In order to solve the problems of increased energy consumption and attenuation of mileage at low temperatures, heat pump technology has been gradually promoted in new energy vehicles. However, under the ultra-low temperature condition of -30°C, the existing heat pump technology is often unable to meet the needs of the passenger compartment or power battery heating. need. Cont...
