Detailed Implementation

[0031] The embodiments of this application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0032] A thermal management assembly 100 according to an embodiment of this application, which is applied to a vehicle, such as a plug-in hybrid electric vehicle, is described below with reference to Figures 1-6.

[0033] As shown in Figure 1, the thermal management assembly 100 according to this application includes a thermal management system 10 and a radiator assembly 20. The thermal management system 10 includes a high-temperature cooling circuit 11, a low-temperature cooling circuit 12, and an air conditioning cooling circuit 13. The radiator assembly 20 includes a first radiator 21, a second radiator 22, and a third radiator 23. The first radiator 21 is selectively connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. The second radiator 22 is selectively connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. The third radiator 23 is selectively connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. The first radiator 21, the second radiator 22, and the third radiator 23 have different performance characteristics.

[0034] It is understood that the thermal management system 10 and the radiator assembly 20 constitute the main structure of the thermal management assembly 100. The high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 constitute the main structure of the thermal management system 10. The high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 are arranged alternately, so that heat dissipation in different modes in the vehicle can be achieved by utilizing the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. The first radiator 21, the second radiator 22, and the third radiator 23 constitute the main structure of the radiator assembly 20. The first radiator 21, the second radiator 22, and the third radiator 23 are selectively connected to the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13, so that the first radiator 21, the second radiator 22, and the third radiator 23 can selectively control the operation of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. This configuration allows for flexible allocation of the first radiator 21, the second radiator 22, and the third radiator 23 to achieve heat dissipation under different operating conditions. It also eliminates auxiliary components such as condensers, heat exchangers, heating devices, or heat storage devices, thereby meeting the heat dissipation needs of different scenarios and saving vehicle energy consumption.

[0035] This application allows a heat sink with higher heat dissipation performance to be connected to the corresponding cooling circuit to meet the heat dissipation requirements. Therefore, the heat dissipation requirements can be met without setting up an additional heat sink, which reduces costs and avoids the problem of limited layout space caused by setting up more heat sinks.

[0036] Therefore, 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 configuration 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. This allows the radiator assembly 20 to be flexibly configured according to different vehicle conditions, thereby enabling the thermal management assembly 100 to adapt to various scenarios.

[0037] Additionally, as shown in Figure 1, the thermal management assembly 100 also includes a valve assembly 30. The first radiator 21 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 through the valve assembly 30. The second radiator 22 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 through the valve assembly 30. The third radiator 23 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 through the valve assembly 30.

[0038] In other words, a valve assembly 30 is provided between the first radiator 21 and the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. This valve assembly 30 controls the connection between the first radiator 21 and these circuits, allowing the first radiator 21 to control the operation of one of them. Similarly, a valve assembly 30 is provided between the second radiator 22 and these circuits, allowing the valve assembly 30 to control the connection between the second radiator 22 and these circuits, allowing the second radiator 22 to control the operation of one of them. A valve assembly 30 is installed between the third radiator 23 and the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13. This valve assembly 30 controls the connection between the third radiator 23 and these circuits, allowing the third radiator 23 to control the operation of one of them. This configuration allows the first radiator 21, the second radiator 22, and the third radiator 23 to be flexibly configured according to different vehicle conditions, enabling the thermal management assembly 100 to adapt to various scenarios.

[0039] As shown in Figure 1, the valve assembly 30 includes a first four-way valve 31, which is provided with a first valve port, a second valve port, a third valve port and a fourth valve port.

[0041] The valve assembly 30 also includes a first three-way valve 32, which is provided with a fifth valve port, a sixth valve port and a seventh valve port, the sixth valve port being selectively connected to one of the fourth valve port and the first radiator 21.

[0042] In other words, the first three-way valve 32 is provided with a fifth valve port, a sixth valve port and a seventh valve port.

Moreover, the sixth valve port is selectively connected to one of the fourth valve port and the first radiator 21, so that the first four-way valve 31 and the first radiator 21 can be selectively connected, thereby achieving heat dissipation under different operating conditions.

The eighth valve port is connected to the seventh valve port, and the ninth valve port is connected to the air conditioning cooling circuit 13. It can be understood that the eighth, ninth, and tenth valve ports on the second three-way valve 33 are arranged alternately to form a "T"-shaped channel. The eighth valve port is connected to the seventh valve port, thereby connecting the first three-way valve 32 and the second three-way valve 33. The ninth valve port is connected to the air conditioning cooling circuit 13, thus enabling heat dissipation under different operating conditions.

The eleventh valve port is connected to the tenth valve port, the twelfth valve port is selectively connected to the third valve port and one of the second radiator 22, the thirteenth valve port is connected to the high-temperature cooling circuit 11, and the fourteenth valve port is connected to the third radiator 23.

[0045] In other words, the first reversing valve 34 is provided with an eleventh valve port, a twelfth valve port, a thirteenth valve port, and a fourteenth valve port. The eleventh valve port, the twelfth valve port, the thirteenth valve port, and the fourteenth valve port are evenly spaced. The eleventh valve port is connected to the tenth valve port, so that the second three-way valve 33 and the first reversing valve 34 can be connected. The twelfth valve port is selectively connected to one of the third valve port and the second radiator 22, so that the first reversing valve 34 and the first four-way valve 31 can be selectively connected, and the first reversing valve 34 and the second radiator 22 can be selectively connected, thereby achieving heat dissipation under different operating conditions.

[0046] The valve assembly 30 also includes a second four-way valve 35, which is provided with a fifteenth valve port, a sixteenth valve port, a seventeenth valve port and an eighteenth valve port. The fifteenth valve port is connected to the high-temperature cooling circuit 11, and the sixteenth valve port is selectively connected to one of the second valve port and the thirteenth valve port.

[0047] Understandably, the second four-way valve 35 is provided with a fifteenth, sixteenth, seventeenth, and eighteenth valve ports, which are evenly spaced. The fifteenth valve port is connected to the high-temperature cooling circuit 11, thereby connecting the second four-way valve 35 and the high-temperature cooling circuit 11. The sixteenth valve port is selectively connected to one of the second and thirteenth valve ports, thereby connecting the second four-way valve 35 and the first four-way valve 31, or connecting the second four-way valve 35 and the first reversing valve 34, thus enabling heat dissipation under different operating conditions.

The nineteenth valve port, the twentieth valve port, the twenty-first valve port, and the twenty-second valve port are evenly spaced. The nineteenth valve port is connected to the third radiator 23, so that the second directional valve 36 and the third radiator 23 can be connected. The twentieth valve port is connected to the eighteenth valve port, so that the second directional valve 36 and the second four-way valve 35 can be connected, thereby realizing heat dissipation under different operating conditions.

[0050] The valve assembly 30 also includes a third three-way valve 37, which has a 23rd, 24th, and 25th valve port. The 23rd valve port is connected to the second radiator 22, and the 24th valve port is connected to the 21st valve port. It can be understood that the 23rd, 24th, and 25th valve ports on the third three-way valve 37 are arranged alternately to form a "T"-shaped channel. The 23rd valve port is connected to the second radiator 22, thus allowing the third three-way valve 37 to connect with the second radiator 22.

[0051] The valve assembly 30 also includes a fourth three-way valve 38, which has a 26th valve port, a 27th valve port, and a 28th valve port. The 27th valve port is connected to the first radiator 21. In other words, the fourth three-way valve 38 has a 26th valve port, a 27th valve port, and a 28th valve port, which are arranged alternately to form a "T"-shaped channel. The 27th valve port is connected to the first radiator 21, thereby allowing the fourth three-way valve 38 and the first radiator 21 to be connected.

[0052] Valve assembly 30 also includes a fifth three-way valve 39, which has a 29th, 30th, and 31st valve port. The 29th valve port is connected to the 17th valve port, and the 31st valve port is connected to the 26th valve port. It can be understood that the 29th, 30th, and 31st valve ports on the fifth three-way valve 39 are arranged alternately to form a "T"-shaped channel. The 29th valve port is connected to the 17th valve port, thus allowing the fifth three-way valve 39 to connect with the second four-way valve 35. The 31st valve port is connected to the 26th valve port, thus allowing the fifth three-way valve 39 to connect with the fourth three-way valve 38.

[0053] The valve assembly 30 also includes a third directional valve 40, which is provided with a 32nd valve port, a 33rd valve port, a 34th valve port and a 35th valve port.

The 34th valve port is connected to the 28th valve port. The 35th valve port is selectively connected to one of the air conditioning cooling circuit 13 and the 5th valve port.

[0054] In other words, the third directional valve 40 is provided with a 32nd, 33rd, 34th, and 35th valve port, which are evenly spaced. The 32nd valve port is selectively connected to one of the low-temperature cooling circuit 12 and the 30th valve port, thereby connecting the third directional valve 40 to the low-temperature cooling circuit 12, or connecting the third directional valve 40 to the fifth three-way valve 39. The 33rd valve port is connected to the 25th valve port, thereby connecting the third directional valve 40 to the third three-way valve 37. The 34th valve port is connected to the 28th valve port, thereby connecting the third directional valve 40 to the fourth three-way valve 38. The 35th valve port is selectively connected to one of the air conditioning cooling circuit 13 and the fifth valve port, thereby connecting the third directional valve 40 to the air conditioning cooling circuit 13, or connecting the third directional valve 40 to the first three-way valve 32.

[0055] As shown in Figure 2, the first radiator 21 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 via the sixth valve port of the first three-way valve 32, the eighth valve port of the second three-way valve 33, the twenty-seventh valve port of the fourth three-way valve 38, the thirty-fourth valve port of the third reversing valve 40, and the thirty-fifth valve port of the third reversing valve 40. This arrangement allows the first radiator 21 to be connected to the air conditioning cooling circuit 13, thereby achieving the vehicle's cooling operation.

[0056] The second radiator 22 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 via the third port of the first four-way valve 31, the thirty-second port and the thirty-third port of the third reversing valve 40, and the twenty-fifth port of the third three-way valve 37. This arrangement allows the second radiator 22 to be connected to the low-temperature cooling circuit 12, thereby achieving the vehicle's cooling operation.

[0057] The third radiator 23 is connected to one of the high-temperature cooling circuit 11, the low-temperature cooling circuit 12, and the air conditioning cooling circuit 13 via the thirteenth valve port of the first reversing valve 34, the fourteenth valve port of the first reversing valve 34, the nineteenth valve port of the second reversing valve 36, and the twentieth valve port of the second reversing valve 36. This arrangement allows the third radiator 23 to be connected to the high-temperature cooling circuit 11, thereby achieving the vehicle's cooling operation.

[0058] Furthermore, as shown in Figures 3-5, when the heat pump conditions are met, the connection between the first radiator 21 and the air conditioning cooling circuit 13 is switched to the connection between the first radiator 21 and the low-temperature cooling circuit 12; the connection between the second radiator 22 and the low-temperature cooling circuit 12 is switched to the selective connection between the second radiator 22 and the high-temperature cooling circuit 11; and the connection between the third radiator 23 and the high-temperature cooling circuit 11 is switched to the connection between the third radiator 23 and the air conditioning cooling circuit 13, thus achieving the purpose of a heat pump. This configuration allows the vehicle to switch from cooling mode to heat pump mode by switching between the first radiator 21, the second radiator 22, and the third radiator 23 and the low-temperature cooling circuit 12, the high-temperature cooling circuit 11, and the air conditioning cooling circuit 13.

[0059] When defrosting conditions are met, the connection between the first radiator 21 and the air conditioning cooling circuit 13 is switched to the connection between the first radiator 21 and the low-temperature cooling circuit 12; the connection between the second radiator 22 and the low-temperature cooling circuit 12 is switched to the connection between the second radiator 22 and the air conditioning cooling circuit 13; and the third radiator 23 is connected to the high-temperature cooling circuit 11, thus achieving the purpose of defrosting. This configuration allows the vehicle to switch from cooling mode to defrosting mode by switching between the first radiator 21, the second radiator 22, and the third radiator 23 and the low-temperature cooling circuit 12, the high-temperature cooling circuit 11, and the air conditioning cooling circuit 13.

[0060] When the conditions for fast charging and increasing the heat exchange area of ​​the external heat exchanger are met, the first radiator 21 is connected to the air conditioning cooling circuit 13, the second radiator 22 is connected to the low-temperature cooling circuit 12, which is then switched to the second radiator 22 being connected to the air conditioning cooling circuit 13, and the third radiator 23 being connected to the low-temperature cooling circuit 12, thus achieving the purpose of fast charging and increasing the heat exchange area of ​​the external heat exchanger. This configuration allows the vehicle to switch between cooling mode and fast charging / increased heat exchange area by switching between the first radiator 21, the second radiator 22, and the third radiator 23 and the low-temperature cooling circuit 12, the high-temperature cooling circuit 11, and the air conditioning cooling circuit 13.

[0061] Furthermore, as shown in Figure 1, the cryogenic cooling circuit 12 includes a water-cooled intercooler 121, a drive unit 122, and a controller 123. The drive unit 122 and the controller 123 are connected in series and in parallel with the water-cooled intercooler 121. It can be understood that the water-cooled intercooler 121, the drive unit 122, and the controller 123 constitute the main structure of the cryogenic cooling circuit 12. The drive unit 122 and the controller 123 are connected in series, and the drive unit 122 and the water-cooled intercooler 121 are connected in parallel, thus facilitating the controller 123 to control the operation of the drive unit 122, thereby facilitating the water-cooled intercooler 121 to reduce the intake air temperature and improve the charging efficiency of the energy unit 111. For example, the drive unit 122 can be a motor, and the controller 123 can be a multi-functional controller, thus facilitating the controller 123 to control the operation of the drive unit 122.

[0062] Additionally, as shown in Figure 1, the low-temperature cooling circuit 12 also includes a low-temperature cooling water pump 124. The low-temperature cooling water pump 124 is connected in series with the water-cooled intercooler 121, and is also connected in series with the drive unit 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 drive unit 122, and the controller 123, respectively. This allows the low-temperature cooling water pump 124 to circulate low-temperature water and lower the cooling temperature, thus ensuring the cooling effect.

[0063] Furthermore, as shown in Figure 1, 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. Moreover, the series connection allows the energy component cooling water pump 112 to pump external water to the energy component 111, thereby dissipating heat from the external water and improving the operating efficiency of the energy component 111.

[0064] In addition, as shown in Figure 1, 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. That is, the water-cooled condenser 131 and the air conditioning cooling water pump 132 constitute the main structure of the air conditioning cooling circuit 13, and the series connection allows condensate to circulate in the water-cooled condenser 131 and enables the air conditioning cooling water pump 132 to provide a stable temperature and pressure to the air conditioning cooling circuit 13.

[0065] Specifically, as shown in Figure 1, the first radiator 21, the second radiator 22, and the third radiator 23 are arranged side by side. This 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 the different operating conditions of the vehicle.

[0066] Specifically, as shown in Figures 2-6, the thermal management assembly 100 can meet the following operating conditions.

[0067] The first type: refrigeration mode, as shown in Figure 2, 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, 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 mode is heat pump operation. When the vehicle is in pure electric mode, as shown in Figure 3, the first radiator 21 is a low-temperature radiator, the third radiator 23 is an air conditioning radiator, and the second radiator 22 is not working. At this time, the third radiator 23 acts as an external heat exchanger, absorbing heat from the air. After the intake 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 conditioning. Moreover, the heated air can raise the intake air temperature of the third radiator 23, thereby reducing the risk of frost formation on the external heat exchanger. It will not affect the interior heating or battery heating, and no other auxiliary heating methods are required, thus achieving 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 unit 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, as shown in Figure 4, 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. In this mode, the third radiator 23 acts as an external heat exchanger, absorbing heat from the air. After the intake air is heated by the first and second radiators 21 and 22, it provides more outdoor air heat to the third radiator 23, thereby enhancing the performance of the heat pump air conditioning. Furthermore, the heated air increases the intake air temperature of the third radiator 23, reducing the risk of frost formation on the external 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 unit 122, 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 unit cooling water pump 112, the energy unit 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 mode is defrosting, as shown in Figure 5. When the vehicle is in pure electric mode, under heat pump operation, through the mode switching of the thermal management assembly 100, the first radiator 21 becomes a low-temperature radiator, and the third radiator 23 becomes an air conditioning radiator. At this time, the third radiator 23 acts as an external heat exchanger, thus absorbing heat from the air. After the intake 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 conditioning. Moreover, the heated air can increase the intake air temperature of the third radiator 23, thus reducing the risk of frosting on the external heat exchanger. If the third radiator 23 frosts, 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 becomes a high-temperature radiator. When the third radiator 23 frosts, the functions of the first radiator 21 and the third radiator 23 are switched.

[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 unit 122, 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 unit cooling water pump 112, the energy unit 111, and the first reversing valve 34 are connected in sequence.

[0072] The fourth type: fast charging mode and heat pump mode with increased heat exchange area of ​​the external heat exchanger, as shown in Figure 6. When the vehicle is in pure electric mode, the first radiator 21 and the second radiator 22 are connected in series to form an air conditioning radiator, which can increase 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 fast charging. At this time, the air conditioning radiator is an external heat exchanger, which can absorb heat from 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 third reversing valve 40, 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 unit 122 and the controller 123, the first four-way valve 31, and the first reversing valve 34 are connected in sequence.

[0074] The vehicle 200 according to this application includes the thermal management assembly 100 of the above embodiments, as shown in FIG7. 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 configuration 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. This allows the radiator assembly 20 to be flexibly configured according to different vehicle conditions, thereby enabling the thermal management assembly 100 to adapt to various scenarios.
