Description

Technical Field

[0001] The present invention relates to a thermal management system for a new energy vehicle, in particular to an integrated thermal management system with a six-way valve which can fully utilize the heat dissipation of a motor. Background Art

[0003] New energy vehicles are paying more and more attention to vehicle thermal management technology. The current technical development of thermal management systems for new energy vehicles has evolved from simple distributed three-electric thermal management to integrated three-electric thermal management, and a variety of three-electric thermal coupling systems have been developed. Through effective integrated thermal management technology, energy loss caused by temperature problems can be reduced. For example, batteries working at a suitable temperature can improve their charging and discharging efficiency and reduce energy loss; cooling of motors and electronic control units can also reduce performance degradation caused by overheating and improve overall energy utilization efficiency. At the same time, the thermal management system of new energy vehicles is an important part of ensuring vehicle safety. By monitoring and controlling the temperature of batteries, motors and electronic control units, safety accidents such as thermal runaway can be prevented. The thermal management system can also work in conjunction with the vehicle's air conditioning system, using the heat or coolant generated by the battery to heat or cool the passenger compartment to improve passenger comfort. Through vehicle integrated thermal management, the motor and battery can be kept in the optimal operating temperature range with the highest efficiency. Combined with heat pump air conditioning technology, the vehicle's endurance can be further improved.

[0004] However, at lower ambient temperatures, even if new energy vehicles use heat pump technology to absorb heat from the environment, the air conditioning power consumption is still high, which further increases the vehicle's endurance degradation. When the ambient temperature is below a certain level, such as -10°C, some thermal management systems can only use electric heaters for heating, and the compressor cannot be started due to the low ambient temperature. At this time, the endurance degradation is more serious. At the same time, many existing integrated thermal management technologies use eight-way valves, ten-way valves, and even twelve-way valves to integrate the vehicle's thermal management circuit, but the more valve ports a multi-way valve has, the more complex the system structure will be; on the other hand, since all thermal management lines are integrated / connected to the multi-way valve, the multi-way valve becomes the "hub" of the vehicle's thermal management system. Once the eight-way valve, ten-way valve, or twelve-way valve fails, not only is the difficulty of fault location and repair very high, but it can also sometimes lead to safety accidents. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes an integrated thermal management system with a six-way valve, which can not only utilize the heat dissipation of the motor to make the heat pump system more efficient, but also the control valve only uses simple three-way valves and six-way valves, with simple structure and complete functions.

[0007] Furthermore, in the present invention, the heater is a PTC heater, and the first heat exchanger, the second heat exchanger, and the third heat exchanger are all double-channel plate heat exchangers.

[0008] Furthermore, in the present invention, the three-way valve is a two-position three-way valve.

[0011] Furthermore, the present invention also includes a generator, which is connected in series in the motor electronic control circulation pipeline and is located between the motor and the controller.

[0012] Furthermore, in the present invention, the function of the three-way valve is realized by a first two-way valve and a second two-way valve.

[0028] Working condition 4: The cab needs to be slightly heated, and the battery 16, motor 18, and controller 19 need to be cooled

[0029] The A and C ports of the three-way valve 24 are controlled to be connected, and the A and B ports of the three-way valve 24 are isolated; the H and J ports of the six-way valve 8 are connected, the E and F ports are connected, and the D and G ports are connected; the first expansion valve 21, the second expansion valve 22, and the third expansion valve 23 are closed; the first circulation pump 25, the second circulation pump 26, and the third circulation pump 27 are running, and the compressor 9 is stopped.

[0030] Working condition 5: The cab needs to be heated, and the battery 16, motor 18, and controller 19 need to be cooled

[0031] The A and B ports of the three-way valve 24 are controlled to be connected, and the A and C ports of the three-way valve 24 are blocked; the J and D ports of the six-way valve 8 are connected, the E and F ports are connected, and the H and G ports are connected; the first expansion valve 21, the second expansion valve 22, and the third expansion valve 23 are closed; the first circulation pump 25, the second circulation pump 26, and the third circulation pump 27 are running, and the compressor 9 is stopped.

The heat pump system absorbs the heat of the motor 18 and the controller 19 through the second heat exchanger 13, thereby improving the working efficiency of the compressor 9 in a low temperature environment; at the same time, the heat pump air conditioning system does not directly absorb the heat of the environment through the radiator 20, which can effectively prevent the radiator 20 from frosting in a low temperature environment. If the heat required by the cab and the battery 16 is still insufficient, the heater 17 is turned on to allow the heater 17 to heat the indoor heater core 15 and the battery 16 at the same time.

[0040] If the battery 16, the motor 18, and the electronic control 19 need to dissipate heat at this time, the A and C ports of the three-way valve 24 are controlled to be connected, and the A and B ports are isolated; the J and F ports of the six-way valve 8 are connected, and the H and G ports are connected; at the same time, the second circulation pump 26 and the third circulation pump 27 are controlled to operate; the battery 16, the motor 18, and the electronic control 19 dissipate heat to the environment through the radiator 20.

[0041] The above are only the working principles of nine main operating conditions. In addition, there are other operating conditions, and the relevant principles will not be stated here one by one.
