[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish different objects, not to limit a specific order. The various embodiments of this utility model described below can be performed individually, or they can be combined with each other; this utility model does not impose specific limitations in this regard.

[0036] Figure 1 This is a structural diagram of a thermal management system provided in an embodiment of the present invention.

[0037] like Figure 1 As shown, the thermal management system includes:

[0038] The heat exchange and waste heat recovery module 10 is electrically connected to the central controller 30 and is used to realize the heat transfer between various heat source devices and collect the waste heat of each heat source device under the control of the central controller 30.

[0039] The energy storage and distribution module 20 is electrically connected to the heat exchange and waste heat recovery module 10 and the central controller 30, respectively. It is used to convert the waste heat recovered by the heat exchange and waste heat recovery module 10 into electrical energy for storage, and distribute it to each heat source device under the control of the central controller 30.

[0040] The central controller 30 is configured to control the heat exchange and waste heat recovery module 10 and the energy storage and distribution module 20 to perform corresponding actions based on the operating conditions of the vehicle where the thermal management system is located, the temperature status of each heat source device, and the ambient temperature information.

[0041] Specifically, the heat exchange and waste heat recovery module 10 includes multiple heat exchangers, such as an engine coolant-air heat exchanger, a battery coolant-air heat exchanger, and an engine coolant-battery coolant heat exchanger. These heat exchangers are used to transfer heat between different media, for example, transferring the heat generated by the engine to the battery coolant to preheat the battery. Simultaneously, the heat exchange and waste heat recovery module 10 is also equipped with a waste heat recovery device, which can be a waste heat recovery heat pump or other devices capable of collecting and converting excess heat for utilization. The waste heat recovery device can recover the waste heat generated by components of heat source equipment such as the engine and motor, and use it for heating air in the vehicle's air conditioning system or for battery insulation.

[0042] Optionally, the energy storage and distribution module 20 includes one of the following: a supercapacitor or a battery. Specifically, the energy storage and distribution module 20 is equipped with an energy storage device, which can be a supercapacitor or a small battery, used to convert the waste heat recovered by the heat exchange and waste heat recovery module 10 into electrical energy and store it in the energy storage device. Simultaneously, the energy storage and distribution module 20 can also, according to the instructions of the central controller 30, rationally distribute the stored electrical energy to components that need heating, such as engine preheating and battery insulation, or distribute the stored electrical energy to other devices that require electricity, such as the vehicle's dashboard, to achieve efficient energy utilization.

[0043] The central controller 30, as the core control unit of the entire thermal management system, is configured to acquire the operating conditions of the vehicle, the temperature status of each heat source device, and the ambient temperature information, and analyze and process the acquired data. The central controller 30 incorporates a hierarchical collaborative control strategy and a waste heat recovery strategy, enabling it to formulate the optimal thermal management control scheme based on the temperature status of each heat source device, the vehicle's operating conditions, and the ambient temperature information. It then sends control commands to each actuator to achieve heat transfer control and improve the vehicle's energy utilization rate.

[0044] This invention solves the technical problem of low vehicle energy utilization and environmental pollution caused by the inability of existing thermal management systems to rationally utilize the waste heat generated by heat source equipment by setting up an energy storage and distribution module. It converts the waste heat of each heat source equipment into electrical energy for storage and use, thereby achieving the technical effect of improving vehicle energy utilization and reducing environmental pollution.

[0045] Figure 2 This is a structural diagram of another thermal management system provided in an embodiment of the present invention.

[0046] like Figure 2 As shown, the heat exchange and waste heat recovery module 10 includes multiple heat exchangers 11 and a waste heat recovery pump 12.

[0047] Multiple heat exchangers 11 are installed at each heat source device, including at least an engine coolant-air heat exchanger, a battery coolant-air heat exchanger, and an engine coolant-battery coolant heat exchanger; a waste heat recovery pump 12 is integrated into the coolant circulation loop of the thermal management system to collect waste heat from each heat source device.

[0048] For example, the central controller 30 analyzes the operating conditions of the vehicle where the thermal management system is located, the temperature status of each heat source device, and the ambient temperature information based on the built-in hierarchical collaborative control strategy and waste heat recovery strategy.

[0049] If the central controller 30 determines that the engine is in the cold start stage, the central controller 30 controls the engine coolant-battery coolant heat exchanger to work, using the heat generated during the engine preheating process to heat the battery and improve battery activity; at the same time, when the engine temperature rises to a certain level, the excess heat is recovered by the waste heat recovery heat pump and stored in the energy storage and distribution module 20.

[0050] If the central controller 30 determines that the battery temperature is higher than the preset temperature, the central controller 30 controls the battery coolant circulation, prioritizing the sending of the heat generated by the battery to the waste heat recovery pump 12 for recovery and standby. If the energy storage and distribution module 20 is fully charged, it can continue to dissipate heat through the battery coolant-air heat exchanger. If the central controller 30 determines that the ambient temperature is low, it can also use the waste heat stored in the energy storage and distribution module 20 to heat the battery coolant and maintain the battery at a suitable operating temperature.

[0051] In controlling the ambient temperature inside the vehicle, when heating is needed, the central controller 30 prioritizes using the heat recovered by the waste heat recovery pump 12 to heat the vehicle interior through the air conditioning heating system; if the waste heat is insufficient, the heater is activated for auxiliary heating. When cooling is needed, the central controller 30 controls the air conditioning cooling system to operate, while simultaneously recovering and storing the waste heat generated during the cooling process to prevent heat accumulation.

[0052] Optionally, such as Figure 2 As shown, the thermal management system also includes a multi-source heat acquisition module 40;

[0053] The multi-source heat acquisition module 40 is electrically connected to the central controller 30 and is used to acquire the current temperature data of each heat source device and the ambient temperature information.

[0054] Optionally, see Figure 2 The multi-source heat acquisition module 40 includes multiple device temperature sensors 41 and an ambient temperature sensor 42;

[0055] Multiple device temperature sensors 41 are respectively installed at each heat source device to obtain the current temperature data of each heat source device; the ambient temperature sensor 42 is installed on the vehicle where the thermal management system is located to obtain the ambient temperature information of the vehicle.

[0056] Specifically, the heat source equipment includes at least the vehicle's engine, battery system, motor, and electronic control unit (ECU). Each heat source device is equipped with a device temperature sensor 41 to acquire the current temperature data of the heat source device in real time. The ambient temperature sensor 42 can acquire the ambient temperature information of the environment in which the vehicle is located in real time. The current temperature data and ambient temperature information are transmitted to the central controller 30 through the data bus so that the central controller 30 can determine the temperature status of each heat source device and whether the environment in which the vehicle is currently located is a high temperature or a cold environment, and control the heat transfer in the thermal management system based on the determination result.

[0057] Optionally, such as Figure 2 As shown, the thermal management system also includes a heat dissipation and heating execution module 50;

[0058] The heat dissipation and heating execution module 50 is electrically connected to the central controller 30 and is used to adjust the temperature of each heat source device and the vehicle under the control of the central controller 30.

[0059] Specifically, the heat dissipation and heating execution module 50 is equipped with multiple devices for heat dissipation or heating. These devices are directly controlled by the central controller 30. Based on the preset hierarchical collaborative control strategy and waste heat recovery strategy, the working status of each device in the heat dissipation and heating execution module 50 is adjusted to achieve optimal heat regulation of the vehicle thermal management system.

[0060] Optionally, the heat dissipation and heating execution module 50 includes multiple cooling fans, multiple radiators, multiple heaters, and an air conditioning heating system;

[0061] Multiple cooling fans and multiple radiators are respectively installed at each heat source device to reduce the temperature of each heat source device under the control of the central controller 30;

[0062] Multiple heaters and air conditioning heating systems are installed throughout the vehicle interior to provide heat to the interior environment or various heat source devices under the control of the central controller 30.

[0063] Multiple heaters and air conditioning heating systems are connected to the energy storage and distribution module 20;

[0064] The energy storage and distribution module 20 is also configured to send the stored waste heat into the heater or air conditioning heating system under the control of the central controller 30.

[0065] Specifically, the heat dissipation equipment in the heat dissipation and heating execution module 50 includes cooling fans, radiators, etc., which are used to reduce the temperature of heat source equipment such as engines and batteries; the heating equipment includes heaters, air conditioning heating systems, etc., which can provide heat to the vehicle interior environment or batteries or engines as needed.

[0066] Optionally, the central controller 30 includes a status determination unit, an operating condition determination unit, and a control unit.

[0067] The status determination unit is configured to determine the temperature status of each heat source device in the vehicle and the ambient temperature information based on the information collected by the multi-source heat acquisition module 40. The temperature status includes at least one of the following: engine cold start stage, battery temperature higher than preset temperature, air conditioning heating state, and air conditioning cooling state.

[0068] The operating condition determination unit is configured to acquire the current operating parameters of the vehicle and determine the operating condition of the vehicle, wherein the current operating parameters include at least engine speed, pedal position, and road surface condition;

[0069] The control unit is electrically connected to the status determination unit and the operating condition determination unit, and is configured to control the heat exchange and waste heat recovery module and the energy storage and distribution module to perform corresponding actions based on the vehicle's operating conditions, the temperature status of each heat source device and the ambient temperature information.

[0070] Specifically, the central controller 30 adopts a hierarchical collaborative control strategy. During the execution of the primary collaborative control strategy, the state determination unit and the operating condition determination unit can determine the current operating status of each heat source device. The control unit performs preliminary control of heat transfer based on the preset temperature threshold of each heat source device. For example, when the engine temperature exceeds the upper limit, the cooling fan and radiator are started; when the battery temperature is too low, the battery heating function is activated.

[0071] During the execution of the advanced collaborative control strategy, the control unit, based on the determination results of the state determination unit and the operating condition determination unit, comprehensively considers factors such as the vehicle's operating conditions (e.g., urban congestion, high-speed driving, rapid acceleration, rapid deceleration), ambient temperature information, the temperature status and temperature change trends of each heat source device, and the energy storage status of the energy storage distribution module 20. It then dynamically adjusts the operating modes and parameters of each heat source device in the thermal management system through optimization algorithms. For example, in urban congestion conditions, frequent engine starts and stops lead to unstable heat generation. The central controller 30 will prioritize using the waste heat stored in the energy storage distribution module 20 to heat the vehicle interior, reducing heater energy consumption. During high-speed driving, it will rationally adjust the cooling fan speed according to airflow conditions to further reduce energy consumption.

[0072] Specifically, if the state determination unit determines that the temperature state is in the engine cold start stage, the control unit controls the engine coolant-battery coolant heat exchanger to work, using the heat generated during the engine preheating process to heat the battery and improve battery activity; at the same time, when the engine temperature rises to a certain level, the excess heat is recovered by the waste heat recovery pump 12 and stored in the energy storage and distribution module 20.

[0073] If the status determination unit determines that the battery temperature is higher than the preset temperature, the control unit controls the battery coolant circulation, prioritizing the sending of the heat generated by the battery to the waste heat recovery pump 12 for recovery and standby. If the energy storage and distribution module 20 is fully charged, it can continue to dissipate heat through the battery coolant-air heat exchanger. If the status determination unit determines that the ambient temperature is low, it can also use the waste heat stored in the energy storage and distribution module 20 to heat the battery coolant and maintain the battery at a suitable operating temperature.

[0074] If the status determination unit determines that the air conditioning is in heating mode, the control unit prioritizes using the heat recovered by the waste heat recovery pump 12 to heat the vehicle interior through the air conditioning heating system; if the waste heat is insufficient, the heater is activated for auxiliary heating. When the status determination unit determines that the air conditioning is in cooling mode, the control unit controls the air conditioning cooling system to operate, while simultaneously recovering and storing the waste heat generated during the cooling process to prevent heat accumulation.

[0075] In this embodiment of the invention, before the thermal management system is put into operation, the hierarchical collaborative control strategy and waste heat recovery strategy within the central controller 30 are debugged and optimized to ensure that it can make reasonable control decisions accurately based on different operating conditions and data. During vehicle operation, the multi-heat source acquisition module 40 collects data in real time and transmits it to the central controller 30. The central controller 30 controls the collaborative operation of each heat source device according to a preset strategy, achieving efficient operation of the thermal management system. During operation, system operation data is continuously collected, and the control algorithm and strategy are optimized and updated to improve the performance and adaptability of the thermal management system.
