Embodiment 1

[0068] Hardware structure: see figure 1 — Figure 8, a thermal management system for a gasoline-electric hybrid commercial vehicle, comprising an engine 13, a drive motor 5, an all-in-one controller 52, an ISG generator 55, an ISG controller 56, a power battery 4, a compressor 31, and a motor radiator 53 , condenser 32, first heat exchanger 6, second heat exchanger 7 and third heat exchanger 8; described first heat exchanger 6 comprises first first inlet 61 of intercommunication, first first outlet 62 and first second inlet 63 of intercommunication, First two outlets 64, second heat exchanger 7 includes intercommunicating second one inlet 71, second one outlet 72 and intercommunicating second second inlet 73, second second outlet 74, third heat exchanger 8 includes intercommunicating third one inlet 81, third one outlet 82 With intercommunicating second inlet 83 and second outlet 84, the first outlet 62 communicates with the second inlet 71, the second outlet 74 communicates ...

Embodiment 2

[0074] The hardware structure is the same as that of Embodiment 1, but the method of use is different, and the differences are:

[0075] see figure 2 , image 3 and Figure 4 , the method of use is not the deep cooling process of the battery and the motor in turn, but the battery heating process during the heat engine. Including the following two waterways that are conducted simultaneously:

[0076] B2 outlet 84, water pump 3 41, power battery 4, A2 inlet 63, A2 outlet 64, B2 inlet 83 battery deep cooling waterway; C1 outlet 82, water pump 1 51, ISG controller 56, multiple Integrating controller 52, ISG generator 55, drive motor 5, B2 inlet 73, B2 outlet 74, C1 inlet 81 constitute the motor deep cooling water circuit. In application, the power battery 4 is heated up by the waste heat of the drive motor 5, taking into account the dual requirements of cooling the motor and heating the battery.

[0077] In addition, when the motor needs shallow cooling, there is another met...

Embodiment 3

[0079] On the basis of the hardware structure of Embodiment 1, a water pump 2 91 , a water heater 9 , a warm air core 23 , an evaporator 2 21 , a blower 2 22 and an electronic expansion valve 2 2 are added.

[0080] see Image 6 , the figure is a schematic diagram of the water circuit for battery heating when the machine is cold, and the specific process is: the outlet of water pump 2 91, the water heater 9 (preferably PTC), the inlet of B2 73, the outlet of B2 74, the inlet of C1 81, the outlet of C1 Exit 82, water pump two 91 inlets form water heating and heating waterway; meanwhile, the second battery outlet 84, water pump three 41, power battery 4, first two inlet 63, first second outlet 64, second second inlet 83 battery deep cooling At this time, the water circuit exchanges heat with the water heating water circuit in the heat exchanger to increase the temperature of the power battery 4 .

Abstract

A thermal management system for an oil-electric hybrid commercial vehicle and its use method, mainly including an engine, a compressor, a heat exchanger, a heat exchanger B, a heat exchanger C, a drive motor, an all-in-one controller, an ISG generator, The ISG controller and the power battery constitute the refrigerant flowing waterway, the battery deep cooling waterway, the motor deep cooling waterway, and the motor shallow cooling waterway. Any one of the process and motor shallow cooling process. On this basis, water pump 2 and water heater can be added to ensure the temperature rise of the battery when the machine is cold, and a warm air core, evaporator 2, and blower 2 can be added to realize the rise of the cab. 1. Cooling down and heating up the cab There are two types according to whether the engine dissipates heat, so as to manage the energy of the refrigerant and the heat generated by the vehicle. This design not only has better energy management effect and lower equipment cost, but also has better compatibility effect and is easy to control.

Description

technical field [0001] The invention relates to a thermal management system for a vehicle, which belongs to the technical field of new energy vehicles, and in particular to a thermal management system and a use method of an oil-electric hybrid commercial vehicle. Background technique [0002] At present, the cooling and heating systems of various gasoline-electric hybrid vehicles on the market are independent of each other, such as gasoline-electric hybrid light trucks and gasoline-electric hybrid refrigerated vehicles, which not only leads to unreasonable energy distribution, reduces energy utilization, and makes Each area that needs to be heated or cooled requires a separate heating or cooling system, which increases the cost of the equipment. [0003] The disclosure of information in this background section is only intended to increase the understanding of the general background of this patent application, and should not be considered as an acknowledgment or any form of s...
