The driver 122 and controller 123 are connected in series, and the driver 122 and the water-cooled intercooler 121 are connected in parallel.

For example, the driver 122 is a motor, and the controller 123 is an all-in-one controller 123, so that the controller 123 can control the operation of the driver 122.

[0062] In addition, if Figure 1 As shown, the low-temperature cooling circuit 12 further includes a low-temperature cooling water pump 124, which is connected in series with the water-cooled intercooler 121. The low-temperature cooling water pump 124 is also connected in series with the driver 122 and the controller 123. In other words, the low-temperature cooling water pump 124 is connected in series with the water-cooled intercooler 121, the driver 122, and the controller 123, respectively. This allows the low-temperature cooling water pump 124 to circulate low-temperature water to reduce the cooling temperature, thereby ensuring a cooling effect.

[0063] In addition, if Figure 1 As shown, the high-temperature cooling circuit 11 includes: an energy component 111 and an energy component cooling water pump 112, which are connected in series. It can be understood that the energy component 111 and the energy component cooling water pump 112 constitute the main structure of the high-temperature cooling circuit 11, and the energy component 111 and the energy component cooling water pump 112 are connected in series, so that the energy component cooling water pump 112 can pump external water to the energy component 11, and then the external water can dissipate heat from the energy component 111, thereby improving the working efficiency of the energy component 111.

[0064] In addition, Figure 1As shown, the air conditioning cooling circuit 13 includes a water-cooled condenser 131 and an air conditioning cooling water pump 132, which are connected in series. In other words, the water-cooled condenser 131 and the air conditioning cooling water pump 132 constitute the main structure of the air conditioning cooling circuit 13. The water-cooled condenser 131 and the air conditioning cooling water pump 132 are connected in series, so that the condensed water can circulate in the water-cooled condenser 131 and the air conditioning cooling water pump 132 can provide a stable temperature and pressure for the air conditioning cooling circuit 13.

[0065] In particular, if Figure 1 As shown, the first radiator 21, the second radiator 22 and the third radiator 23 are arranged side by side. Such an arrangement facilitates the installation of the first radiator 21, the second radiator 22 and the third radiator 23, as well as the switching between the first radiator 21, the second radiator 22 and the third radiator 23, thereby meeting different working conditions of the vehicle.

[0066] Specifically, if Figure 2-Figure 6 As shown, the thermal management assembly 100 can meet the following working conditions.

[0067] The first type: refrigeration condition, the first radiator 21 is an air-conditioning radiator, the second radiator 22 is a low-temperature radiator, and the third radiator 23 is a high-temperature radiator. The first radiator 21, the fourth three-way valve 38, the third reversing valve 40, the air-conditioning cooling water pump 132, the water-cooled condenser 131, the second three-way valve 33 and the first three-way valve 32 are connected in sequence; the second radiator 22, the third three-way valve 37, the third reversing valve 40, the low-temperature cooling water pump 124, the water-cooled intercooler 121, the drive component 122 and the controller 123 and the first four-way valve 31 are connected in sequence; the third radiator 23, the second reversing valve 36, the second four-way valve 35, the energy component cooling water pump 112, the energy component 111 and the first reversing valve 34 are connected in sequence.

[0068] The second type: heat pump working condition. When the vehicle is in pure electric mode, the first radiator 21 is a low-temperature radiator, the third radiator 23 is an air-conditioning radiator, and the second radiator 22 stops working. At this time, the third radiator 23 is an outdoor heat exchanger, which can absorb heat in the air. After the inlet air temperature is heated by the first radiator 21, it can provide more outdoor air heat source for the third radiator 23, thereby enhancing the performance of the heat pump air conditioner. The heated air can increase the inlet air temperature of the third radiator 23, thereby reducing the risk of frost on the outdoor heat exchanger, and will not affect the heating in the car or battery heating, and no auxiliary heating means are required, thereby achieving the purpose of energy saving. For example, the first radiator 21, the fourth three-way valve 38, the fifth three-way valve 39, the low-temperature cooling water pump 124, the water-cooled intercooler 121, the drive 122 and the controller 123 and the first four-way valve 31 are connected in sequence; the third radiator 23, the second reversing valve 36, the air-conditioning cooling water pump 132, the water-cooled condenser 131, the second three-way valve 33 and the first reversing valve 34 are connected in sequence.

[0069] When the vehicle is in hybrid mode, the first radiator 21 is a low-temperature radiator, the second radiator 22 is a high-temperature radiator, and the third radiator 23 is an air-conditioning radiator. At this time, the third radiator 23 is an outdoor heat exchanger, which can absorb heat from the air. After the inlet air temperature is heated by the first radiator 21 and the second radiator 22, more outdoor air heat sources can be provided to the third radiator 23, thereby enhancing the performance of the heat pump air conditioner. Moreover, the heated air can increase the inlet air temperature of the third radiator 23, thereby reducing the risk of frost on the outdoor heat exchanger. For example, the first radiator 21, the fourth three-way valve 38, the fifth three-way valve 39, the low-temperature cooling water pump 124, the water-cooled intercooler 121, the drive 122 and the controller 123 and the first four-way valve 31 are connected in sequence; the second radiator 22, the third three-way valve 37, the second reversing valve 36, the second four-way valve 35, the energy component cooling water pump 112, the energy component 111 and the first reversing valve 34 are connected in sequence; the third radiator 23, the second reversing valve 36, the air-conditioning cooling water pump 132, the water-cooled condenser 131, the second three-way valve 33 and the first reversing valve 34 are connected in sequence.

[0070] The third type: defrost condition. When the vehicle is in pure electric mode, under the heat pump condition, through the mode change of the thermal management assembly 100, the first radiator 21 is a low-temperature radiator and the third radiator 23 is an air-conditioning radiator. At this time, the third radiator 23 is an outdoor heat exchanger, which can absorb heat from the air. After the inlet air temperature is heated by the first radiator 21, it can provide more outdoor air heat source for the third radiator 23, thereby enhancing the performance of the heat pump air conditioner. Moreover, the heated air can increase the inlet air temperature of the third radiator 23, thereby reducing the risk of frost on the outdoor heat exchanger. If the third radiator 23 is frosted, the second radiator 22 becomes an air-conditioning radiator and the third radiator 23 becomes a low-temperature radiator, so that the low-temperature cooling circuit 12 can be used to defrost the third radiator 23 without affecting the air-conditioning cooling circuit 13. When the vehicle switches to hybrid mode, the second radiator 22 is a high-temperature radiator. When the third radiator 23 is frosted, the functions of the first radiator 21 and the third radiator 23 are swapped.

[0071] For example, the first radiator 21, the fourth three-way valve 38, the fifth three-way valve 39, the low-temperature cooling water pump 124, the water-cooled intercooler 121, the drive 122 and the controller 123 and the first four-way valve 31 are connected in sequence; the second radiator 22, the third three-way valve 37, the second reversing valve 36, the air-conditioning cooling water pump 132, the water-cooled condenser 131, the second three-way valve 33 and the first reversing valve 34 are connected in sequence; the third radiator 23, the second reversing valve 36, the second four-way valve 35, the energy component cooling water pump 112, the energy component 111 and the first reversing valve 34 are connected in sequence.

[0072] The fourth type: fast charging condition and heat pump condition that increases the heat exchange area of the external heat exchanger. When the vehicle is in pure electric mode, the first radiator 21 and the second radiator 22 are connected in series as an air-conditioning radiator, thereby increasing the heat exchange area of the water-cooled condenser 131. The third radiator 23 is a low-temperature radiator, which can meet the heat dissipation requirements of vehicle fast charging. At this time, the air-conditioning radiator is an external heat exchanger, which can absorb heat in the air and increase the heat exchange area of the external heat exchanger, thereby improving the performance of the heat pump system and reducing the energy consumption of the air-conditioning cooling circuit 13.

[0073] For example, the first radiator 21, the fourth three-way valve 38, the second reversing valve 36, the third three-way valve 37, the second radiator 22, the first reversing valve 34, the second three-way valve 33, the water-cooled condenser 131, the air-conditioning cooling water pump 132 and the first three-way valve 32 are connected in sequence; the third radiator 23, the second reversing valve 36, the second four-way valve 35, the fifth three-way valve 39, the low-temperature cooling water pump 124, the water-cooled intercooler 121, the drive 122 and the controller 123, the first four-way valve 31 and the first reversing valve 34 are connected in sequence.

[0074] The vehicle according to the present invention includes: the thermal management assembly 100 of the above embodiment, by connecting the high-temperature cooling circuit 11, the low-temperature cooling circuit 12 and the air-conditioning cooling circuit 13 to the first radiator 21, the second radiator 22 and the third radiator 23. This arrangement allows the first radiator 21, the second radiator 22 and the third radiator 23 to be selectively connected to at least one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12 and the air-conditioning cooling circuit 13, so that the radiator assembly 20 can be flexibly adjusted according to different vehicle conditions, and thus the thermal management assembly 100 can be adapted to a variety of scenarios.
