Problems solved by technology

The existing electric drive thermal management system is independent of the air conditioner thermal management system and the battery thermal management system. The cooling of the electric drive thermal management system and the battery thermal management system are independent of each other. In the electric drive thermal management system, the motor or electronic control generates The heat of the battery is dissipated through the radiator in the electric drive thermal management system. In the battery thermal management system, the cooling of the battery mainly depends on the air conditioning thermal management system, which needs to be activated even when the battery cooling demand is low and the passenger compartment has no cooling demand. Although the thermal management system of the air conditioner has a good cooling effect, it increases the energy consumption burden of the vehicle

Embodiment Construction

[0035] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0036] Such as Figure 1 to Figure 3 As shown, the present disclosure provides a vehicle thermal management system, including an air-conditioning system, a battery and an electric drive thermal management system, and a heat exchanger 4. The air conditioning system and the battery and electric drive thermal management system can exchange heat to realize the cooling of the battery and electric drive thermal management system by the air conditioning system. Wherein, the battery and electric drive thermal management system includes a first coolant flow path, a second coolant flow path, a first three-way valve 5 and a second three-way valve 15 .

Abstract

The present disclosure relates to a vehicle thermal management system and a vehicle. The vehicle thermal management system includes an air conditioning system, a battery and an electric drive thermal management system, and a heat exchanger. The heat exchanger is simultaneously set in the air conditioning system and the battery and electric drive thermal management system. , the battery and electric drive thermal management system includes a first coolant flow path, a second coolant flow path, a first three-way valve and a second three-way valve, a power battery and a heat exchanger are arranged on the first coolant flow path, A motor and a radiator are arranged on the second coolant flow path, one end of the first coolant flow path is connected to the A port of the first three-way valve, and the other end is connected to the B port of the first three-way valve and the port of the second three-way valve. Port C is connected, one end of the second coolant flow path is connected to port A of the second three-way valve, and the other end is connected to port B of the second three-way valve and port C of the first three-way valve. In this way, the cooling of the power battery no longer depends only on the air conditioning system, and the power battery can also be cooled by the radiator, thereby reducing the energy consumption burden of the vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle manufacturing, and in particular, to a vehicle thermal management system and a vehicle using the vehicle thermal management system. Background technique [0002] The vehicle thermal management system includes three major systems: the air-conditioning thermal management system, the battery thermal management system and the electric drive thermal management system. The existing electric drive thermal management system is independent of the air conditioner thermal management system and the battery thermal management system. The cooling of the electric drive thermal management system and the battery thermal management system are independent of each other. In the electric drive thermal management system, the motor or electronic control generates The heat of the battery is dissipated through the radiator in the electric drive thermal management system. In the battery thermal management system, ...
