The battery cooler 2 can communicate with the air compressor 4, the cab evaporator, and the cab condenser through the refrigerant flow channel 12. The battery heater 3 can communicate with the coolant channel of the engine through the engine coolant flow channel 13. The battery can be cooled by the heat exchange between the refrigerant and the battery coolant using the battery cooler 2. At the same time, the battery can be heated by the heat exchange between the engine coolant and the battery coolant using the battery heater 3. By using the thermal management integrated module of the present invention, the battery cooler 2, the battery heater 3, and the air compressor 4 are integrated on the flow channel plate 1. At the same time, the battery coolant flow channel 11, the refrigerant flow channel 12, and the engine coolant flow channel 13 are integrated, making the thermal management integrated module of the present invention occupy a small space and be convenient for assembly. Moreover, the flow channel plate 1 can be installed inside the footrest of the hybrid vehicle without occupying the space on the side of the rear frame of the cab, reserving a layout space for hybrid vehicles with large batteries and large fuel tanks, effectively solving the problem that the thermal management integrated module of hybrid vehicles in the prior art occupies a relatively large space, resulting in a compact layout space.

[0037] In some embodiments, the thermal management integration module further includes a battery water pump 5. The battery water pump 5 is installed on the flow channel plate 1 and is located on the battery coolant flow channel 11.

[0039] Specifically, in order to adjust the amount of engine coolant entering the battery heater 3. In the present invention, the thermal management integration module further includes a proportional valve 7. The proportional valve 7 is installed on the flow channel plate 1 and is located on the engine coolant flow channel 13.

[0040] Specifically, as Figure 1 and Figure 4 shown, the refrigerant flow channel 12 includes a first flow channel 121 and a second flow channel 122. Among them, the first interface of the battery cooler 2 is connected to the air compressor 4 and the cab evaporator through the first flow channel 121.

At the same time, the fourth interface of the battery cooler 2 is communicated with the first interface of the battery heater 3 through the fourth flow path 112, and the second interface of the battery heater 3 can be communicated with the inlet of the battery coolant supply device through the fifth flow path 113. With such a setting, the purpose of connecting the battery coolant supply device, the battery cooler 2, and the battery heater 3 can be achieved, thereby realizing the circulation of the battery coolant. At the same time, the third flow path 111, the fourth flow path 112, and the fifth flow path 113 are integrated on the flow path plate 1, improving the integration degree of the thermal management integration module and reducing the occupied space.

[0043] Specifically, in order to realize the heat exchange between the battery heater 3 and the engine coolant, an engine coolant inlet joint 14 is provided on the flow path plate 1, and an engine coolant outlet joint 31 is provided on the battery heater 3. The engine coolant inlet joint 14 is communicated with the engine coolant outlet joint 31 through the engine coolant flow path 13. With such a setting, heat exchange can be carried out between the engine coolant and the battery coolant in the battery heater 3, thereby achieving the purpose of heating the battery.

[0044] Furthermore, the thermal management integration module further includes a support frame 9. Among them, the support frame 9 is installed on the flow path plate 1, and the air compressor 4 is arranged on the support frame 9, which facilitates the installation and disassembly of the air compressor 4.

The battery cooler 2 can be connected to the air compressor 4, the cab evaporator, and the cab condenser through the refrigerant flow channel 12. The battery heater 3 can be connected to the coolant channel of the engine through the engine coolant flow channel 13. The battery cooler 2 can cool the battery through the heat exchange between the refrigerant and the battery coolant. At the same time, the battery heater 3 can heat the battery through the heat exchange between the engine coolant and the battery coolant. In the hybrid vehicle of the present invention, the battery cooler 2, the battery heater 3, and the air compressor 4 are integrated on the flow channel plate 1. At the same time, the battery coolant flow channel 11, the refrigerant flow channel 12, and the engine coolant flow channel 13 are integrated, so that the thermal management integration module of the present invention occupies a small space and is convenient for assembly. In addition, the flow channel plate 1 can be installed inside the footrest of the hybrid vehicle, without occupying the space on the side of the rear frame of the cab, reserving layout space for the hybrid vehicle with a large battery and a large fuel tank, effectively solving the problem that the thermal management integration module of the hybrid vehicle in the prior art occupies a large space, resulting in a compact layout space.
