Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a thermal management system, a suspension system and a vehicle. BACKGROUND

[0002] The thermal management system mainly includes a refrigerant cycle and a water cooling cycle. In the existing thermal management system, the refrigerant cycle is mainly used for cooling and heating of the passenger compartment and the battery, and the water cooling cycle is mainly used for cooling of components such as the drive motor, the control system and the engine.

[0003] The suspension system is an assembly of all parts connecting the vehicle body and the wheels, and has functions of supporting the vehicle body, absorbing road impact, improving comfort, adjusting the posture of the vehicle body, improving maneuverability, and ensuring that the wheel jumping has a normal motion track. The suspension system classification includes passive suspension, semi-active suspension and full-active suspension. The elasticity and damping of the passive suspension cannot change with external conditions. The semi-active suspension has no power source, and only the resistance element is controllable. The full-active suspension can replace the damping and elastic elements by using electric control components (power source) according to the motion state of the vehicle, and actively controls the vehicle motion. The electric control component has certain energy consumption. When the suspension active output is large, only air convection heat exchange cannot meet the performance requirements, and forced cooling is required. The existing technology lacks a suspension temperature regulating system, which causes the temperature of the suspension system to be too high, the suspension system to be severely worn, and the service life to be reduced.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0064] Suspension system as the assembly of all parts connecting the vehicle body and the wheels, has the functions of supporting the vehicle body, absorbing road impact, improving comfort, adjusting the posture of the vehicle body, improving the handling, ensuring the normal movement track of the wheel jumping, etc. The classification of suspension system includes passive suspension, semi-active suspension and full-active suspension. The elasticity and damping of passive suspension cannot change with external conditions. Semi-active suspension has no power source, only resistance elements are controllable. Full-active suspension can replace damping and elastic elements by using electric control components (power source) according to the motion state of the whole vehicle, and actively control the motion of the vehicle. The electric control component has certain energy consumption, when the active output of the suspension is large, only air convection heat exchange cannot meet the performance requirements, forced cooling is needed. The prior art lacks a suspension temperature regulation system, which leads to high temperature of the suspension system, reduces the performance and service life of the suspension system.

[0065] In view of this, the present application provides a thermal management system, Figures 1 to 8 The structure schematic diagram of an embodiment of the thermal management system provided by the present application can adjust the temperature of the suspension system, avoid high temperature of the suspension system, and improve the working performance and service life of the suspension system. The thermal management system will be described in detail below in combination with the main drawings.

[0066] According to the first aspect of the present application, referring to Figure 1 The present application provides a thermal management system 100, which comprises a first heat exchanger 2, a first thermal management circulation system and a suspension cooling circulation system 50. The suspension cooling circulation system 50 is used for adjusting the temperature of the suspension system of the vehicle, and the suspension cooling circulation system 50 exchanges heat with the first thermal management circulation system through the first heat exchanger 2.

[0067] In the thermal management system 100 provided by the present application, the suspension cooling circulation system 50 cools the suspension system, adjusts the temperature of the suspension system, avoids high temperature of the suspension system, and improves the working performance and service life of the suspension system; the suspension cooling circulation system 50 is connected to the first thermal management circulation system through the first heat exchanger 2, when the temperature of the suspension cooling circulation system is too high, the first thermal management circulation system exchanges heat with the suspension cooling circulation system 50 through the first heat exchanger 2, assists the suspension cooling circulation system 50 to work, avoids high temperature of the suspension system, and improves the working performance and service life of the suspension system.

[0068] In some embodiments, the first thermal management circulation system is also used for adjusting the temperature of the first component of the vehicle, avoiding high temperature of the first component, so that the first component is in a suitable temperature state, and improving the working efficiency of the first component.

[0069] In some embodiments, the first component includes a powertrain; in other embodiments, the first component includes a power controller; and in still other embodiments, the first component includes both a powertrain and a power controller.

[0070] In this embodiment, the first component includes a powertrain, a power controller assembly, an OBC controller, and other components. Further, the powertrain includes multiple drive motors or engines, and the power controller assembly includes multiple drive motor controllers. The suspension system includes a suspension controller and a suspension assembly.

[0071] Please see Figure 1 The thermal management system 100 includes a main cooling cycle system 10, a refrigeration cycle system 20, a DC / IDC cooling cycle system 30, and a suspension cooling cycle system 50. The main cooling cycle system 10 is used for cooling the first component, the refrigeration cycle system 20 is used for cooling or heating the passenger compartment, and the refrigeration cycle system 20 can also be used to cool the battery system. The DC / IDC cooling cycle system 30 is used for cooling the DC and IDC, and the suspension cooling cycle system 50 is used for cooling the suspension assembly. In this embodiment, the suspension system includes a suspension assembly and a suspension controller. Considering that the controller generates relatively little heat and requires continuous cooling, in this embodiment, the suspension controller cooling component is located in the main cooling cycle system, and the main cooling cycle system cools the suspension controller, resulting in a reasonable layout and energy savings.

[0072] Please see Figure 1 and Figure 2 The main cooling cycle system 10 is connected to the refrigeration cycle system 20 via the first heat exchanger 2. The refrigeration cycle system 20 includes a compressor 203, a condenser 201, and an expansion valve 204 connected in sequence. More specifically, the first heat exchanger 2 is connected between the compressor 203 and the expansion valve 204 to convert the refrigerant from a liquid state to a gaseous state through the expansion valve 204, providing refrigeration temperature and cooling capacity. The working principle of the refrigeration cycle system 20 is as follows: after the refrigerant is pressurized by the compressor 203, it releases heat in the condenser 201, then flows through the expansion valve 204 to reduce pressure and temperature, and then flows through the first heat exchanger 2 into the suspension cooling cycle system 50 to absorb the heat generated by the suspension cooling cycle system 50, and finally flows into the compressor 203 to complete the refrigeration cycle. In this cycle, the suspension cooling cycle system 50 and the first heat exchanger 2 act as evaporators.

[0073] In addition, the refrigeration cycle system 20 also includes an integrated module 202. One end of the integrated module 202 is connected between the compressor 203 and the first heat exchanger 2, and the other end is connected between the condenser 201 and the expansion valve 204. The specific configuration of the integrated module 202 can be referred to the configuration in the field.

[0074] Please continue reading. Figure 2The suspension cooling circulation system 50 includes a main suspension cooling circulation path. In the circulation direction of the main suspension cooling circulation path, a second water pump 51 and a suspension cooling component 13 are sequentially arranged. The suspension cooling component 13 is located between the first heat exchanger 2 and the second water pump 51. Specifically, the cooling medium passes through the first heat exchanger 2, which absorbs the heat of the cooling medium and converts the high-temperature cooling medium into a low-temperature cooling medium. After being pressurized by the first water cooling system, the low-temperature cooling medium flows into the suspension cooling component 13 to absorb the heat of the suspension components. Finally, it flows back into the first heat exchanger 2, thereby regulating the temperature of the suspension components, preventing the suspension components from overheating, and improving the performance and service life of the suspension components.

[0075] In some embodiments, the first component includes a powertrain and a power controller, and the suspension system includes a suspension controller; the main cooling circulation system 10 is used to regulate the temperature of the powertrain, the power controller, and the suspension controller. The main cooling circulation system 10 includes a power cooling component 16, a power controller cooling component 15, and a suspension controller cooling component. In the circulation direction of the main cooling circulation system 10, the suspension controller cooling component, the power controller cooling component 15, and the power cooling component 16 are arranged sequentially. In this embodiment, the suspension controller is sensitive to temperature and requires a suitable temperature to function properly. Prolonged exposure to high temperatures can damage the suspension controller; therefore, the suspension controller cooling component is positioned at the front to ensure proper cooling of the suspension controller.

[0076] For more details, please continue reading. Figure 1 The main cooling cycle system includes a power cooling component 16, a power controller cooling component 15, and a suspension controller cooling component. The power cooling component 16 is used to cool the powertrain, the suspension controller cooling component is used to cool the suspension controller, and the power controller cooling component 15 is used to cool the power controller.

[0077] In this embodiment, the powertrain includes a front powertrain and a rear powertrain. The front powertrain includes a first drive motor and a second drive motor, and the rear powertrain includes a third drive motor and a fourth drive motor. The power controller includes a front power controller and a rear power controller. The front power controller includes a first power controller and a second power controller, and the rear power controller includes a third power controller and a fourth power controller. The suspension controller includes a first suspension controller and a second suspension controller. The power cooling component 16 includes a front power cooling component and a rear power cooling component. The power controller cooling component 15 includes a front power controller cooling component and a rear power controller cooling component. The suspension controller cooling component includes a first suspension controller cooling component 131 and a second suspension controller cooling component 132.

[0078] Please continue reading. Figure 1The first main water circulation path 11 includes two first water circulation branches 14 connected in parallel. One first water circulation branch 14 includes a front power controller cooling component and a front power cooling component connected in series, while the other first water circulation branch 14 includes a rear power controller cooling component and a rear power cooling component connected in series. The front power controller cooling component cools the corresponding front power controller, and the front power cooling component cools the corresponding front power assembly. The rear power controller cooling component cools the corresponding rear power controller, and the rear power cooling component cools the corresponding rear power assembly. This arrangement rationally allocates space, utilizes energy efficiently, improves cooling efficiency, and saves resources.

[0079] Furthermore, the front power controller cooling component includes a first controller cooling component 151 and a second controller cooling component 152 connected in series, and the rear power controller cooling component includes a third controller cooling component 153 and a fourth controller cooling component 154 connected in series. The front power cooling component includes two power cooling sub-pipes 161 connected in parallel, which are respectively the first drive motor cooling component 1611 and the second drive motor cooling component 1612, and the rear power cooling component includes two power cooling sub-pipes 161 connected in parallel, which are respectively the third drive motor cooling component 1613 and the fourth drive motor cooling component 1614. The first controller cooling component 151 is used to cool the first controller, the second controller cooling component 152 is used to cool the second controller, the third controller cooling component 153 is used to cool the third controller, the fourth controller cooling component 154 is used to cool the fourth controller, the first drive motor cooling component 1611 is used to cool the first drive motor, the second drive motor cooling component 1612 is used to cool the second drive motor, the third drive motor cooling component 1613 is used to cool the third drive motor, and the fourth drive motor cooling component 1614 is used to cool the fourth drive motor.

[0080] In some embodiments, please refer to Figure 1 The suspension controller is integrated into the OBC controller. The main cooling circulation system 10 also includes an OBC cooling component 17. The OBC cooling component 17, the first suspension controller cooling component 131, and the second suspension controller cooling component 132 are connected in series and located in any one of the first water circulation branches 14. The first suspension controller cooling component 131 is used to cool the corresponding first suspension controller, the second suspension controller cooling component 132 is used to cool the corresponding second suspension controller, and the OBC cooling component 17 is used to cool the OBC controller.

[0081] In other embodiments, please refer to Figure 5The main cooling circulation system 10 also includes an OBC cooling component 17, which is connected in series with the first suspension controller cooling component 131 and is located in any one of the first water circulation branches 14. The second suspension controller cooling component 132 is located in another first water circulation branch 14.

[0082] Please continue reading. Figure 1 The main cooling circulation system 10 includes a first water pump 12 and a second main water circulation path 18. The first water pump 12 has an inlet and an outlet. One end of the first main water circulation path 11 is connected to the inlet, and the other end is connected to the outlet. The first main water circulation path 11 includes a suspension controller cooling component for cooling the suspension controller, and the suspension controller cooling component is located near the inlet. One end of the second main water circulation path 18 is connected to the outlet of the first main water circulation path 11 via the first water pump 12, and the other end is connected to the inlet of the first main water circulation path 11. The first main water circulation path 11 and the second main water circulation path 18 are connected to form a complete cooling circulation loop. Further, the second main water circulation path 18 is connected to the refrigeration circulation system 20 via a second heat exchanger 3 for heat exchange with the refrigeration circulation system 20. When the refrigeration cycle system 20 is in heat pump mode, it exchanges heat with the main cooling cycle system 10, absorbing heat from the main cooling cycle system 10 for heating the passenger compartment, while simultaneously lowering the temperature of the main cooling cycle system 10. This configuration optimizes energy utilization, improves energy efficiency, and saves resources.

[0083] Furthermore, the second water circulation main road 18 includes a second water circulation branch road 181, a third water circulation branch road 182, and a fourth water circulation branch road 183, with the three branches applied in three different environmental conditions.

[0084] Under normal operating conditions, when the main cooling circulation system is cooled by the first radiator assembly 1811, one end of the second water circulation branch 181 is connected to the outlet of the first water circulation main 11, and the other end of the second water circulation branch 181 is connected to the inlet of the first water circulation main 11. The second water circulation branch 181 is equipped with the first radiator assembly 1811, and heat is dissipated through the first radiator assembly 1811, thereby completing the cooling cycle. Specifically, the cooling method of the water cooling circulation system is as follows: the cooling medium flows out from the first radiator assembly 1811, sequentially cooling the suspension controller cooling component, the power controller cooling component 15, and the power cooling component 16, and then flows into the first water pump 12. After being pressurized by the first water pump 12, it flows into the second water circulation branch 181, and then into the first radiator assembly 1811. After being dissipated by the first radiator assembly 1811, it flows into the second water circulation main 181, thereby completing the cooling cycle.

[0085] In some embodiments, when the refrigeration cycle system 20 is in heat pump mode and needs to recover heat from the main cooling cycle system 10, one end of the third water circulation branch 182 is connected to the outlet of the first water circulation main 11 through the first connection node 184, and the other end of the third water circulation branch 182 is connected to the second water circulation branch 181 through the second connection node 185. In the circulation direction of the main cooling cycle system 10, the second connection node 185 is located before the first radiator assembly 1811 (it should be noted that "before" and "after" here do not refer to the positional relationship, but rather to the position in the circulation direction of the main cooling cycle system 10). The second heat exchanger 3 is located in the third water circulation branch 182, and the third water circulation branch 182 is cooled through the second heat exchanger 3 to recover heat from the main cooling cycle system 10. The third circulation branch is also provided with a connector 187, which is located after the second heat exchanger 3. The second circulation branch also includes a third circulation sub-branch, one end of which is connected to the connector 187, and the other end is connected to the first water circulation branch 14 through the second connection node 185. More specifically, the cooling medium flows directly from the connector 187 into the second connection node 185, sequentially cooling the suspension controller assembly, suspension assembly, and powertrain before flowing into the first water pump 12. After being pressurized by the first water pump 12, it flows into the third water circulation branch 182. The third water circulation branch 182 is equipped with a second heat exchanger 3, which cools the cooling medium, reducing its temperature. Subsequently, it flows into the connector 187 and then into the third water circulation sub-branch 1821. The third water circulation sub-branch 1821 is then connected to the second water circulation branch 181 via the second connection node 185. Since the second connection node 185 is located before the first radiator assembly 1811, the cooling medium will no longer pass through the first radiator assembly 1811 and will directly enter the first water circulation main 11, thus completing the cooling cycle. With this configuration, the first heat exchanger 2 is connected to the refrigeration cycle system 20, making reasonable use of the refrigeration cycle system 20 for auxiliary heat dissipation. This not only improves heat dissipation efficiency but also recovers heat for heating the occupant cabin, thereby improving energy utilization.

[0086] In some embodiments, depending on the operating conditions and control strategy, the first heat exchanger 2 and the first radiator assembly 1811 need to cooperate simultaneously for cooling circulation. The second main water circulation path 18 also includes a fourth water circulation branch 183. One end of the fourth water circulation branch 183 is connected to the second water circulation branch 181 through a connector 187, and the other end of the fourth water circulation branch 183 is connected to the first water circulation branch 14 through a third connecting node 186. In the circulation direction of the main cooling circulation system 10, the connector 187 is located after the first heat exchanger 2, and the third node is located after the first radiator assembly 1811 (it should be noted that "after" here does not refer to the front and back in terms of positional relationship, but rather to the front and back in the circulation direction of the main cooling circulation system 10). More specifically, the cooling medium flows out from the first radiator assembly 1811, sequentially cooling the suspension controller assembly, suspension assembly, and powertrain before flowing into the first water pump 12. After being pressurized by the first water pump 12, it flows into the second water circulation branch 181. The second water circulation branch 181 is equipped with a first heat exchanger 2, which cools the cooling medium, reducing its temperature.

[0094] According to a second aspect of this application, a suspension system is provided for heat exchange with the suspension cooling circulation system 50 in the aforementioned thermal management system 100.

[0095] In some embodiments, the suspension system includes an actuator adapted to connect the vehicle body and wheels, and further, the suspension cooling circulation system is also used to cool the actuator.

[0096] It should be noted that the cooling method for the actuator is not limited, as long as cooling is achieved. In some embodiments, the suspension cooling circulation system further includes an actuator cooling section 56 for cooling the actuator. This configuration uses a separate cooling section to cool the actuator, improving cooling efficiency.

[0097] It should be noted that the specific type of the actuator is not limited; the actuator can be a linear motor suspension, a hydraulic suspension, or an air suspension. In this embodiment, the actuator is a linear motor suspension. Temperature is one of the important factors restricting motor performance. When the temperature is too high, it will affect the output and thrust duration of the linear motor, leading to increased energy consumption and reduced linear motor performance. In addition, when the temperature is too high, it will cause the copper loss of the linear motor to increase. Cooling the linear motor through the suspension cooling circulation system keeps the linear motor at a suitable operating temperature, enabling the linear motor to maintain high working efficiency. When the temperature is too high, it will also accelerate the aging of the insulation components of the linear motor, causing the insulation withstand voltage failure, resulting in leakage or even damage and burning of the linear motor. At the same time, when the temperature is too high, it will also cause the permanent magnet of the linear motor to demagnetize, reducing the performance of the linear motor, affecting the mechanical properties of the linear motor, and reducing the reliability and service life of the linear motor. At a suitable operating temperature, the thrust of the linear motor in the suspension system increases, which can improve the suspension's actuation capability under peak conditions.
