[0002] Related technologies typically utilize the method of recovering condensed water from air conditioning systems to achieve liquid water supply. This water production method relies on the air conditions at the evaporator inlet and the energy consumption of the air conditioning system.

The enriched water vapor can be condensed into liquid water by the thermal management component, thereby improving overall water production efficiency. Through the adsorption and desorption processes, the first multimedia heat exchanger concentrates water vapor dispersed in a large volume of air, thereby increasing the water vapor concentration in a local area. This increase in water vapor concentration is equivalent to raising the dew point temperature in that local area. Due to the increased dew point temperature, water vapor is more likely to reach saturation and condense into liquid water under the same cooling conditions. This means that the thermal management system can obtain more liquid water with lower energy consumption. This design also improves the applicability of the thermal management system, enabling effective water production even in relatively dry environments.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0049] This application provides a thermal management system 100, see Figure 1 , Figure 1 This is a schematic structural diagram of the thermal management system 100 provided in an embodiment of the present application.

[0050] The thermal management system 100 includes a first multimedia heat exchanger 10 and a thermal management component.

[0051] The first multimedia heat exchanger 10 can switch between an adsorption state and a desorption state. In the adsorption state, the first multimedia heat exchanger 10 can adsorb water vapor in the air. In the desorption state, the first multimedia heat exchanger 10 can release the adsorbed water vapor.

[0052] It should be noted that when humid air passes through the first multimedia heat exchanger 10, it absorbs moisture and releases heat of adsorption. Due to the low-temperature internal cooling source, the first multimedia heat exchanger 10 can maintain a high adsorption capacity. When the first multimedia heat exchanger 10 reaches moisture saturation, driven by the high-temperature internal heat source, the adsorbed water vapor is released from the first multimedia heat exchanger 10, allowing the first multimedia heat exchanger 10 to regain its adsorption capacity.

[0053] The thermal management component is adapted to provide heat to the first multimedia heat exchanger 10. This heat, acting as a high-temperature internal heat source for the first multimedia heat exchanger 10, releases adsorbed water vapor, thereby switching the first multimedia heat exchanger 10 to a desorption state. Furthermore, the thermal management component can also provide cooling, acting as a low-temperature internal cooling source for the first multimedia heat exchanger 10, condensing the released water vapor into liquid water. Furthermore, the thermal management component precisely regulates both heat and cooling, enabling the first multimedia heat exchanger 10 to automatically switch between adsorption and desorption states, thereby improving dehumidification and water production efficiency.

[0054] In the technical solution of the present application, when the first multimedia heat exchanger 10 is in the adsorption state, the first multimedia heat exchanger 10 can effectively adsorb water vapor from the air. This means that even in an environment with low relative humidity, the thermal management system 100 can collect usable water resources. When the first multimedia heat exchanger 10 switches to the desorption state, the thermal management component provides heat to the first multimedia heat exchanger 10, so that the adsorbed water vapor is released, thereby achieving water vapor enrichment. The enriched water vapor can be condensed into liquid water by the thermal management component, thereby improving the overall water production efficiency. Through the adsorption and desorption processes, the first multimedia heat exchanger 10 can concentrate the water vapor dispersed in a large volume of air, thereby increasing the water vapor concentration in a local area. The increase in water vapor concentration is equivalent to raising the dew point temperature of the local area. Due to the increase in dew point temperature, under the same cooling conditions, water vapor is more likely to reach saturation and condense into liquid water. This means that the thermal management system 100 can obtain more liquid water with lower energy consumption. In addition, this design also improves the applicability of the thermal management system 100, enabling effective water production even in relatively dry environments.

[0055] In some embodiments, at least two first multimedia heat exchangers 10 are provided, with at least one first multimedia heat exchanger 10 in the adsorption state and at least one first multimedia heat exchanger 10 in the desorption state. This allows one portion of the heat exchanger to adsorb water vapor from the air while another portion releases previously adsorbed water vapor through heating, achieving continuous and uninterrupted adsorption and release. The released water vapor can be condensed into liquid water by the thermal management component, thus ensuring continuous water production. Because the thermal management system 100 can perform both adsorption and desorption processes simultaneously, this significantly improves water production efficiency and output. Compared to a thermal management system 100 with only one first multimedia heat exchanger 10, which must wait for a full adsorption-desorption cycle to complete before beginning the next adsorption cycle, the use of multiple first multimedia heat exchangers 10 significantly reduces downtime and increases water production per unit time. Having multiple first multimedia heat exchangers 10 also increases the stability and reliability of the thermal management system 100. If one of the first multimedia heat exchangers 10 fails, the other first multimedia heat exchangers 10 can continue to work, reducing the risk of the entire thermal management system 100 shutting down due to a single point failure and ensuring the continuity of the water production process.

[0056] In some embodiments, each first multi-media heat exchanger 10 includes a first coolant flow channel 11 and an adsorption portion. The first coolant flow channel 11 and the adsorption portion are thermally connected. The adsorption portion is used to adsorb water vapor in the air. The thermal management component includes a coolant circulation loop and two first multi-way valves 21. The coolant circulation loop is used to transport coolant. The two ends of the two first coolant flow channels 11 are arranged in parallel through the two first multi-way valves 21. The two ends of the coolant circulation loop are connected to the two first multi-way valves 21. In this way, the coolant circulation loop can be selectively connected to one of the two first coolant flow channels 11 as needed. When the coolant is transported to the first coolant flow channel 11, the coolant is suitable for heat exchange with the adsorption portion, so that the water vapor adsorbed by the adsorption portion is released, and the first multi-media heat exchanger 10 is switched from the adsorption state to the desorption state, thereby improving the switching efficiency. In addition, the first multi-way valve 21 can isolate the faulty unit to ensure the continuous operation of the thermal management system 100.

[0057] It should be noted that the first multi-media heat exchanger 10, based on the adsorption principle, can meet passenger water requirements in any operating condition and in any mode (internal or external circulation). The treated air can meet the passenger compartment's cooling, heating, and dehumidification requirements without increasing the cabin's heating / cooling load, and can even reduce cabin thermal management energy consumption. The first multi-media heat exchanger 10 can achieve heat exchange between any two of the refrigerant, coolant, air, and adsorption unit, as well as moisture exchange between the air and the adsorption unit.

[0058] In addition, there are various types of adsorption components. For example, in one embodiment, the adsorption component may include a silica gel-based adsorption layer, a molecular sieve, activated alumina, a lithium chloride composite adsorbent, a silica gel-molecular sieve gradient layer, or a graphene-based adsorption membrane. In another embodiment, the adsorption component includes a dehumidification heat exchanger fin, the fin surface of which is coated with a water-absorbing adsorption material.

[0059] Specifically, this application does not limit this. In addition, the first multi-way valve 21 may include a three-way valve, a four-way valve or a five-way valve, etc. Specifically, in the embodiment of the present application, the first multi-way valve 21 is selected as a three-way valve.

[0060] In some embodiments, the two first multi-way valves 21 and the two first coolant flow channels 11 together constitute a desorption unit. The coolant circulation loop includes a motor electronic control system 221, a second multimedia heat exchanger 222, and a third multimedia heat exchanger 223. The second multimedia heat exchanger 222 is configured to be located outside the device so that it can exchange heat with the air outside the device. The third multimedia heat exchanger 223 is configured to be located inside the device so that it can exchange heat with the air inside the device. The motor electronic control system 221 can be optionally connected in series with at least one of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and the desorption unit. In this way, the coolant flowing out of the motor electronic control system 221 can selectively flow through the second multimedia heat exchanger 222, the third multimedia heat exchanger 223 and at least one of the desorption units, so that the coolant can exchange heat with at least one of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223 and the desorption unit to achieve cooling of the coolant.

[0061] It should be noted that when the coolant flowing out of the motor electronic control system 221 flows through the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and one of the desorption units, a first-stage cooling of the coolant can be achieved. When the coolant flowing out of the motor electronic control system 221 flows through two of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and the desorption unit, a second-stage cooling of the coolant can be achieved. When the coolant flowing out of the motor electronic control system 221 flows through the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and the desorption unit, a third-stage cooling of the coolant can be achieved. Specifically, in one embodiment, the motor electronic control system 221 mainly includes a motor, an electronic control, and similar heat-generating components. Of course, in other embodiments, the motor electronic control system 221 can be selected as needed, and this application does not limit this.

[0062] Reference Figures 2 to 5 、 Figure 11 and Figure 12In some embodiments, the coolant circulation loop further includes a second multi-way valve 224, a third multi-way valve 225 and a fourth multi-way valve 226. The second multi-way valve 224 is connected to the outlet end of the motor electronic control system 221. The second multimedia heat exchanger 222 has a second coolant flow channel 2221. One end of the second coolant flow channel is connected to one of the two first multi-way valves 21, the second multi-way valve 224 and the fourth multi-way valve 226 through the third multi-way valve 225. The other end of the second coolant flow channel is connected to the motor electronic control system 221 through the fourth multi-way valve 226. The inlet end of the motor control system 221 is connected, so that the second multi-way valve 224, the third multi-way valve 225 and the fourth multi-way valve 226 work together to realize that the motor electronic control system 221 can be selectively connected in series with the second multi-media heat exchanger 222, the third multi-media heat exchanger 223 and at least one of the desorption units, so that the thermal management system 100 can select the cooling level of the coolant as needed, so that the temperature of the coolant flowing back to the motor electronic control system 221 meets the requirements, thereby improving the service life of the motor electronic control system 221.

[0063] In addition, waste heat from the motor-electronic control system 221 is distributed to at least one of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and the desorption unit via the second multi-way valve 224, the third multi-way valve 225, and the fourth multi-way valve 226. When the waste heat from the motor-electronic control system 221 is transferred to the second multimedia heat exchanger 222 via the coolant, the second multimedia heat exchanger 222 exchanges heat with the air outside the device, discharging the heat from the device. When the waste heat from the motor-electronic control system 221 is transferred to the third multimedia heat exchanger 223 via the coolant, the third multimedia heat exchanger 223 can exchange heat with the air inside the device, heating the air inside the device and reusing the waste heat. When the waste heat from the motor-electronic control system 221 is transferred to the desorption unit via the coolant, the first multimedia heat exchanger 10 corresponding to the desorption unit can be switched from an adsorption state to a desorption state, reusing the waste heat and saving energy.

[0064] In some embodiments, the coolant circulation loop further includes a fifth multi-way valve 227, and the third multi-media heat exchanger 223 has a third coolant flow channel 2231. One end of the third coolant flow channel 2231 is connected to the other of the two first multi-way valves 21 and the second multi-way valve 224 through the fifth multi-way valve 227. In this way, the third coolant flow channel 2231 can be selectively connected to or disconnected from the motor electronic control system 221. When the third coolant flow channel 2231 is connected to the motor electronic control system 221, the coolant output by the motor electronic control system 221 can exchange heat with the third multi-media heat exchanger 223, thereby reducing the temperature of the coolant output by the motor electronic control system 221 (refer to Figure 4 and Figure 5When the third coolant flow channel 2231 is disconnected from the motor electronic control system 221, the third coolant flow channel 2231 can be connected to or disconnected from the first multimedia heat exchanger 10. When the third multimedia heat exchanger 223 is connected to the first multimedia heat exchanger 10, the coolant output by the third multimedia heat exchanger 223 can flow directly to the first multimedia heat exchanger 10, so that the first multimedia heat exchanger 10 is suitable for switching from the adsorption state to the desorption state (refer to Figure 6 and 7 ).

[0065] The other end of the third coolant flow channel 2231 is connected to one of the two first multi-way valves 21. In this way, the other end of the third coolant flow channel 2231 can be selectively connected to or disconnected from the first multimedia heat exchanger 10. When the other end of the third coolant flow channel 2231 is connected to the first multimedia heat exchanger 10, the coolant causes the first multimedia heat exchanger 10 to switch to the desorption state, and the coolant can flow back to the third coolant flow channel 2231 to achieve a circulating flow of the coolant (refer to Figures 4 to 7 and Figure 12 ).

[0066] In some embodiments, the thermal management system 100 further includes a heat dissipation fan 30, which is arranged outside the device and corresponds to the second multimedia heat exchanger 222. In this way, the heat dissipation fan 30 guides the air outside the device to exchange heat with the second multimedia heat exchanger 222, thereby cooling the second multimedia heat exchanger 222, saving costs and being environmentally friendly.

[0067] Reference Figure 1 The thermal management system 100 also includes a heat dissipation duct 1019. Both the heat dissipation fan 30 and the second multimedia heat exchanger 222 are disposed within the heat dissipation duct 1019. This ensures that the heat dissipation fan 30 can exchange heat with the second multimedia heat exchanger 222. Furthermore, the heat dissipation duct 1019 protects the heat dissipation fan 30 and the second multimedia heat exchanger 222.

[0068] It should be noted that the second multimedia heat exchanger 222 can realize heat exchange between any two of the refrigerant, coolant, and air. Since the technology of the second multimedia heat exchanger 222 is mature, this application does not limit the specific structure of the second multimedia heat exchanger 222.

[0069] In some embodiments, the thermal management system 100 further includes a blower 40, which is configured to be located within the device and corresponding to the third multimedia heat exchanger 223. Thus, the blower 40 can, on the one hand, direct airflow toward the third multimedia heat exchanger 223, enabling heat exchange with the third multimedia heat exchanger 223. On the other hand, the blower 40 can also direct airflow toward the first multimedia heat exchanger 10 in a desorption state, where it mixes with the desorbed water vapor to form flowing high-humidity air, facilitating subsequent processing of the high-humidity air.

[0070] It should be noted that the blower 40 can also guide the air flow to the evaporator 241, so that the high-humidity air entering the evaporator 241 is cooled to below the dew point and generates condensed water to meet the water production demand.

[0071] Reference Figures 2 to 5 In some embodiments, the thermal management component includes a heat pump circuit for transporting refrigerant. The thermal management system 100 also includes a first air duct 50. At least two first multimedia heat exchangers 10 are disposed within the first air duct 50. The first air duct 50 is adapted to transport released water vapor to the heat pump circuit for heat exchange, thereby condensing the released water vapor into liquid water. This ensures that at least one of the two first multimedia heat exchangers 10 is always in a desorbing state, enabling continuous water vapor release. The released water vapor is condensed into liquid water through heat exchange with the heat pump circuit, enabling continuous water production.

[0072] Reference Figures 2 to 5 In some embodiments, the thermal management system 100 further includes a driving fan 60, the air outlet of which is connected to the first air duct 50, and the driving fan 60 is used to promote the gas in the first air duct 50 to flow to the heat pump circulation loop. In this way, the driving fan 60 can speed up the speed at which the gas in the first air duct 50 flows to the heat pump circulation loop, thereby improving the water production efficiency.

[0073] Reference Figures 2 to 5In some embodiments, each first multi-media heat exchanger 10 further includes a first refrigerant flow channel 12, which is thermally connected to the first coolant flow channel 11 and the adsorption part. The thermal management component further includes two sixth multi-way valves 23, and the two ends of the two first refrigerant flow channels 12 are arranged in parallel through the two sixth multi-way valves 23. The two ends of the heat pump circulation loop are respectively connected to the two sixth multi-way valves 23. In this way, the heat pump circulation loop can be selectively connected to or disconnected from one of the two first refrigerant flow channels 12. When the refrigerant is transported to the first refrigerant flow channel 12, when the heat pump circulation loop is connected to the first refrigerant flow channel 12, the refrigerant in the first refrigerant flow channel 12 is suitable for heat exchange with the adsorption part, so that the temperature of the adsorption part is cooled, so that the adsorption part has a better adsorption effect, and the adsorption efficiency of the first multi-media heat exchanger 10 is improved.

[0074] Reference Figures 2 to 8 In some embodiments, the two sixth multi-way valves 23 and the two first refrigerant flow channels 12 together constitute an adsorption unit. The heat pump circulation loop includes an evaporator 241, a second multimedia heat exchanger 222, and a third multimedia heat exchanger 223. The second multimedia heat exchanger 222 is configured to be located outside the device, thereby enabling the second multimedia heat exchanger 222 to exchange heat with the air outside the device. The third multimedia heat exchanger 223 is configured to be located inside the device, thereby enabling the third multimedia heat exchanger 223 to exchange heat with the air inside the device. The evaporator 241 can be optionally arranged in series with at least one of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223, and the adsorption unit. In this way, the refrigerant flowing out of the evaporator 241 can selectively flow through the second multimedia heat exchanger 222, the third multimedia heat exchanger 223 and at least one of the adsorption units, so that the refrigerant can exchange heat with at least one of the second multimedia heat exchanger 222, the third multimedia heat exchanger 223 and the adsorption unit, and can switch between multiple modes, thereby improving the versatility of the thermal management system 100.

[0075] Specifically, refer to Figure 2 and Figure 3 In some embodiments, when the refrigerant flowing out of the evaporator 241 passes through the second multimedia heat exchanger 222 and the adsorption unit, the low-temperature refrigerant flowing out of the evaporator 241 can exchange heat with the adsorption unit, thereby reducing the temperature of the adsorption unit and improving the adsorption efficiency of the adsorption unit. The temperature of the refrigerant flowing out of the adsorption unit increases, and then it flows through the second multimedia heat exchanger 222. Since the second multimedia heat exchanger 222 can exchange heat with the air outside the equipment, the refrigerant is cooled, and the temperature of the refrigerant returning to the evaporator 241 is also reduced.

[0076] Reference Figures 4 to 7In some embodiments, when the refrigerant flowing out of the evaporator 241 passes through the third multimedia heat exchanger 223 and the adsorption unit, the low-temperature refrigerant flowing out of the evaporator 241 can exchange heat with the adsorption unit, thereby lowering the temperature of the adsorption unit and improving the adsorption efficiency of the adsorption unit. The temperature of the refrigerant flowing out of the adsorption unit increases. When flowing through the third multimedia heat exchanger 223, the refrigerant exchanges heat with the third multimedia heat exchanger 223, lowering the refrigerant temperature and correspondingly increasing the temperature of the third multimedia heat exchanger 223.

[0077] Reference Figure 8 In some embodiments, when the refrigerant flowing out of the evaporator 241 flows through the third multimedia heat exchanger 223, the temperature of the refrigerant decreases, and the temperature of the corresponding third multimedia heat exchanger 223 increases.

[0078] In some embodiments, the heat pump circulation loop further includes a compressor 242 and a gas-liquid separator 243, and the compressor 242 and the gas-liquid separator 243 are suitable for being arranged in series with the evaporator 241 and / or the third multimedia heat exchanger 223. Thus, when the compressor 242 and the gas-liquid separator 243 are arranged in series with the third multimedia heat exchanger 223 (refer to Figure 12 ), so that after the refrigerant flows back to the compressor 242 through the gas-liquid separator 243, it is compressed by the compressor 242 and becomes a high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant exchanges heat with the third multi-media heat exchanger 223 to reduce the refrigerant temperature, and the corresponding temperature of the third multi-media heat exchanger 223 increases. The third multi-media heat exchanger 223 with an increased temperature can exchange heat with the air to heat the air. When the compressor 242 and the gas-liquid separator 243 are connected in series with the evaporator 241 and the third multi-media heat exchanger 223 (refer to Figures 4 to 8 ), so that after the refrigerant flows back to the compressor 242 through the gas-liquid separator 243, it is compressed by the compressor 242 and becomes a high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant exchanges heat with the third multi-media heat exchanger 223, which reduces the refrigerant temperature. The corresponding temperature of the third multi-media heat exchanger 223 increases, and the refrigerant that has completed the heat exchange flows back to the evaporator 241, achieving a re-cooling of the refrigerant. When the compressor 242 and the gas-liquid separator 243 are connected in series with the evaporator 241 (refer to Figure 2 and Figure 3 ) so that the refrigerant flows back to the compressor 242 through the gas-liquid separator 243 and is compressed by the compressor 242 to become a high-temperature and high-pressure refrigerant, which is convenient for the needs of subsequent steps.

[0079] Specifically, refer to Figure 2 and Figure 8The evaporator 241 is connected to the gas-liquid separator 243 and the sixth multi-way valve 23 via the seventh multi-way valve 1018. Thus, when the evaporator 241 is connected to the sixth multi-way valve 23 via the seventh multi-way valve 1018, the refrigerant flowing out of the evaporator 241 can be used as a cold source to exchange heat with the first multimedia heat exchanger 10 in the adsorption state, thereby improving the adsorption efficiency of the first multimedia heat exchanger 10 in the adsorption state. When the evaporator 241 is connected to the gas-liquid separator 243 via the seventh multi-way valve 1018, the refrigerant flowing out of the evaporator 241 can flow back to the third multimedia heat exchanger 223 through the gas-liquid separator 243 and the compressor 242, allowing the refrigerant to exchange heat with the third multimedia heat exchanger 223, thereby reducing the temperature of the refrigerant.

[0080] Reference Figure 8 In some embodiments, the thermal management system 100 further includes a second air duct 70. The evaporator 241 includes an evaporation air duct, and the third multimedia heat exchanger 223 includes a second heat exchange air duct. The evaporation air duct and the second heat exchange air duct are connected through the second air duct 70. This allows for air circulation between the evaporation air duct and the second heat exchange air duct. For example, low-temperature air in the evaporation air duct can flow into the second heat exchange air duct, thereby cooling the third multimedia heat exchanger 223.

[0081] It should be noted that, in some embodiments, the blower 40, the third multimedia heat exchanger 223, and the evaporator 241 are all disposed in the second air duct 70, thereby making the thermal management system 100 compact and reducing the installation space.

[0082] In some embodiments, the thermal management system 100 further includes a third air duct, and the first multimedia heat exchanger 10 has a dehumidification air duct, which is connected to the second heat exchange air duct through the third air duct, so that the air in the dehumidification air duct and the second heat exchange air duct can achieve gas circulation. For example, when the air in the dehumidification air duct flows to the second heat exchange air duct, the air can be heat exchanged in the third multimedia heat exchanger 223, so that the air temperature rises (refer to Figure 4 and Figure 5 When the air in the second heat exchange duct flows to the dehumidification duct, the air can be adsorbed by the first multi-media heat exchanger 10 to achieve dehumidification of the air (refer to Figure 9 and Figure 10 ).

[0083] It should be noted that the thermal management system 100 also includes an air valve, which is arranged in the third air duct. The air valve controls the conduction or disconnection of the third air duct, so that the air in the dehumidification air duct can be circulated with the second heat exchange air duct as needed.

[0084] Reference Figure 1The output port of the motor electronic control system 221 is connected to a first water pump 91. This first water pump 91 promotes the flow of coolant at the output port of the motor electronic control system 221, providing power for the coolant's circulation, enabling the coolant to circulate and improving the coolant's heat exchange efficiency. Furthermore, a second water pump 92 is connected in series between the fifth multi-way valve 227 and the other of the two first multi-way valves 21. This second water pump 92 provides power for the coolant's circulation, enabling the coolant to circulate and improving the coolant's heat exchange efficiency.

[0085] Reference Figure 1 The thermal management system 100 is further provided with a first expansion valve 1011, which can be optionally connected in series with the evaporator 241. Thus, when the first expansion valve 1011 is connected in series with the evaporator 241, the first expansion valve 1011 can throttle, reduce the pressure, and lower the temperature of the refrigerant, so that the pressure, flow, and temperature of the refrigerant meet actual requirements.

[0086] Reference Figure 1 The thermal management system 100 also includes a second expansion valve 1012, and the third multi-media heat exchanger 223 has a third refrigerant flow channel 2232. One end of the third refrigerant flow channel 2232 is connected to the second expansion valve 1012. In this way, the second expansion valve 1012 can throttle, cool down and reduce the pressure of the refrigerant flowing out of the third refrigerant flow channel 2232, so that the pressure, flow and temperature of the refrigerant meet actual needs.

[0087] Reference Figure 1 The second multimedia heat exchanger 222 further has a second refrigerant flow channel 2222, and the third multimedia heat exchanger 223 further has a third refrigerant flow channel 2232. Figure 1 The thermal management system 100 further includes a first valve body 1013, a second valve body 1014, a third valve body 1015, a fourth valve body 1016, and a fifth valve body 1017, wherein one end of the second refrigerant flow channel 2222 is suitable for being arranged in series with the first valve body 1013 (refer to Figure 12 ), the first expansion valve 1011 and the third valve body 1015 are arranged in series (refer to Figure 3 ,), the evaporator 241 is suitable for being arranged in series with the second valve body 1014 (refer to Figure 4 ), the fourth valve body 1016 is suitable for being arranged in series with the compressor (refer to Figure 3 ), the fifth valve body 1017 is suitable for being arranged in series with the third multimedia heat exchanger 223 (refer to Figure 4 ).

[0088] Specifically, the thermal management system 100 has multiple operating modes, including a first mode, a second mode, a third mode, a fourth mode, and a fifth mode. In the first mode, the thermal management system 100 can produce water, dehumidify, cool the passenger compartment, and cool the motor and electronic control system 221. In the second mode, the thermal management system 100 can produce water, heat the passenger compartment, and cool the motor and electronic control system 221. In the third mode, the thermal management system 100 can only produce water. In the fourth mode, the thermal management system 100 can only dehumidify. In the fifth mode, the thermal management system 100 can heat and dehumidify / defog.

[0089] The following describes in detail the working principle of the thermal management system 100 in each mode (this application takes two first multimedia heat exchangers 10 as an example for description):

[0090] Reference Figure 2 and Figure 3 When the thermal management system 100 is in the first mode, at this time, one of the two first multimedia heat exchangers 10 is in a desorption state, and the other first multimedia heat exchanger 10 is in an adsorption state.

[0091] Reference Figure 2 Under the action of the first water pump 91, the high-temperature coolant, which has absorbed heat and heated up from the motor electronic control system 221, passes through the second multi-way valve 224 and the other of the two first multi-way valves 21 in sequence and enters the first coolant flow channel 11 of the first multi-media heat exchanger 10 in the desorption state, and exchanges heat with the adsorption part of the first multi-media heat exchanger 10 in the desorption state and the air in the first air duct 50, thereby increasing the temperature of the adsorption part and the air. At this time, the coolant acts as an internal heat source to put the first multi-media heat exchanger 10 in the desorption state, thereby releasing the moisture absorbed in the adsorption process. At the same time, driven by blower 40, air flows toward first multimedia heat exchanger 10, which is in a desorbing state. Air then flows into evaporator 241, where it exchanges heat with the low-temperature refrigerant flowing through it. The low-temperature refrigerant, an internal cooling source, cools the air to below its dew point, condensing the moisture in the air and producing liquid water, meeting water production requirements. The saturated cold air, cooled and dehumidified by evaporator 241, is then delivered to the cabin, meeting the passenger compartment's cooling needs.

[0092] The high-temperature coolant, serving as an internal heat source, cools down after exchanging heat with the air and the adsorption unit in the first multi-media heat exchanger 10, which is in a desorbed state. A determination is made as to whether the cooled coolant meets the motor control cooling temperature requirement. If so, the coolant flows directly back to the motor control system 221 through the fourth multi-way valve 226 to cool the motor control. Otherwise, the coolant flows sequentially through one of the two first multi-way valves 21 and the third multi-way valve 225, entering the second coolant flow channel 2221 of the second multi-media heat exchanger 222. After a secondary cooling by exchanging heat with the air in the cooling fan 30 outside the device, the coolant flows back to the motor control system 221 to exchange heat with the motor control, meeting the motor control cooling requirement.

[0093] After releasing heat to the air outside the equipment through the second multimedia heat exchanger 222, the refrigerant is throttled, depressurized, and cooled by the first expansion valve 1011 before entering the evaporator 241 to exchange heat with the air flowing through the evaporator 241. After evaporating and absorbing heat, the refrigerant flows through the seventh multi-way valve 1018 and enters the first refrigerant flow channel 12 of the first multimedia heat exchanger 10 in the adsorption state. Acting as an internal cooling source for the first multimedia heat exchanger 10 in the adsorption state, the refrigerant further evaporates and absorbs heat, thereby lowering the temperature of the adsorption portion of the first multimedia heat exchanger 10 in the adsorption state. The air flowing through the first multimedia heat exchanger 10 in the adsorption state in the first air duct 50 exchanges heat and moisture with the adsorption portion. Moisture in the air is absorbed by the adsorption portion, releasing heat of adsorption. Under the cooling effect of the refrigerant, the air is converted into low-temperature dry air, which is released into the environment or introduced into the passenger compartment to provide cooling, meeting the passenger compartment's cooling needs.

[0094] It should be noted that when the first multi-media heat exchanger 10 in the adsorption state is saturated with adsorption or the first multi-media heat exchanger 10 in the desorption state has completed desorption and water production, the connection state of the two first multi-way valves 21 and the two sixth multi-way valves 23 is adjusted so that the coolant can flow through the first multi-media heat exchanger 10 that is saturated with adsorption, so that the first multi-media heat exchanger 10 that is saturated with adsorption can be switched to the desorption state. The refrigerant can flow through the first multi-media heat exchanger 10 that has completed desorption, so that the first multi-media heat exchanger 10 that has completed desorption can be switched to the adsorption state and re-adsorb water vapor. (As shown in the figure) Figure 3 The principle is the same as above and will not be described here any more, so continuous water production and refrigeration can be achieved.

[0095] In addition, in the first mode, the fresh air / return air is first dehumidified and cooled by the first multi-media heat exchanger 10 in the adsorption state, and then undergoes secondary cooling by the evaporator 241 in the equipment to meet the refrigeration or refrigeration dehumidification requirements; at the same time, the waste heat of the coolant is recovered to drive the first multi-media heat exchanger 10 to desorb and produce water, thereby realizing integrated thermal management within the equipment.

[0096] Reference Figure 4 and Figure 5 When the thermal management system 100 is in the second mode, at this time, one of the two first multimedia heat exchangers 10 is in a desorption state, and the other first multimedia heat exchanger 10 is in an adsorption state.

[0097] Reference Figure 4 In this mode, the high-temperature coolant at the outlet of the motor's electronically controlled thermal system flows sequentially through the third coolant channel 2231 of the third multimedia heat exchanger 223 and the first coolant channel 11 of the first multimedia heat exchanger 10 in a desorption state. The third multimedia heat exchanger 223 exchanges heat with the high-temperature coolant, absorbing the coolant's heat to preheat the air delivered to the passenger compartment. Simultaneously, the first multimedia heat exchanger 10 in a desorption state exchanges heat with the coolant at the outlet of the third multimedia heat exchanger 223, absorbing the coolant's heat. After heating, the desorption-state first multimedia heat exchanger 10 releases the absorbed moisture into the air in the first air duct 50, heating and humidifying the air and converting it into high-temperature, high-humidity air. This high-temperature, high-humidity air then flows through the evaporator 241, where it is cooled below the dew point by the low-temperature refrigerant within the evaporator 241, condensing into liquid water, thereby meeting the water production requirement.

[0098] It should be noted that the humidity of the air at the outlet of evaporator 241 is determined. If the humidity of the air at the outlet of evaporator 241 is greater than the humidity of the return air / air outside the equipment, the air at the outlet of evaporator 241 is passed through the first multimedia heat exchanger 10 in an adsorption state, so that the water vapor in the air can be adsorbed and recovered by the first multimedia heat exchanger 10 in an adsorption state, facilitating subsequent efficient air-to-water production. If the humidity of the air at the outlet of evaporator 241 is not greater than the humidity of the return air / air outside the equipment, it is again determined whether the temperature of the air at the outlet of evaporator 241 is higher than the temperature inside the equipment. If the temperature of the air at the outlet of evaporator 241 is greater than the temperature inside the equipment, the heated air at the outlet of evaporator 241 is passed through the third multimedia heat exchanger 223 for reheating before being sent into the cabin to meet the heating requirements of the passenger compartment. Otherwise, the heated air at the outlet of evaporator 241 is discharged outside the equipment.

[0099] The refrigerant at the outlet of the compressor 242 flows through the third multi-media heat exchanger 223 to release heat, the second expansion valve 1012 to throttle and reduce temperature and pressure, the evaporator 241 to evaporate and absorb heat, the seventh multi-way valve 1018 and the sixth multi-way valve 23, and then enters the first multi-media heat exchanger 10 in the adsorption state to further evaporate and absorb heat, thereby reducing the temperature of the first multi-media heat exchanger 10 in the adsorption state. The humid air flowing through the first multi-media heat exchanger 10 in the adsorption state in the first air duct 50 undergoes heat and moisture exchange with the adsorption part of the first multi-media heat exchanger 10 in the adsorption state. After cooling and dehumidification, it enters the third multi-media heat exchanger 223 and is heated at two stages by the high-temperature refrigerant and coolant flowing through the third multi-media heat exchanger 223, and then is sent into the cabin to meet the heating needs of the passenger cabin.

[0100] In addition, the coolant, after heat exchange and cooling with the first multimedia heat exchanger 10 in the desorption state, enters the second coolant flow channel 2221 of the second multimedia heat exchanger 222 through the second multi-way valve 224 and the third multi-way valve 225. The coolant is then determined to meet the coolant temperature requirement after heat exchange and cooling with the first multimedia heat exchanger 10 in the desorption state. If so, the cooling fan 30 is not activated. Otherwise, the cooling fan 30 is activated, allowing the air outside the equipment to exchange heat with the coolant, thereby further cooling the coolant. The further cooled coolant passes through the fourth multi-way valve 226 and enters the motor electronic control thermal management system 100, meeting the motor electronic control cooling requirements.

[0101] When the first multi-media heat exchanger 10 in the adsorption state is saturated with adsorption / or the first multi-media heat exchanger 10 in the desorption state has completed desorption and water production, the connection state of the two first multi-way valves 21 and the two sixth multi-way valves 23 is adjusted so that the coolant can flow through the first multi-media heat exchanger 10 that is saturated with adsorption, so that the first multi-media heat exchanger 10 that is saturated with adsorption can be switched to the desorption state. The refrigerant can flow through the first multi-media heat exchanger 10 that has completed desorption, so that the first multi-media heat exchanger 10 that has completed desorption can be switched to the adsorption state and re-adsorb water vapor. (such as Figure 5 The principle is the same as above and will not be described here any more, so as to realize continuous water production and heating.

[0102] Furthermore, in the second mode, the first multimedia heat exchanger 10 absorbs high-quality waste heat from the coolant circulation loop as an internal heat source to supply heat to the first multimedia heat exchanger 10 that needs to switch to the desorption state. The low-temperature refrigerant in the heat pump circulation loop serves as an internal cooling source to provide cooling to the first multimedia heat exchanger 10 that needs to be in the adsorption state. These two modes achieve efficient desorption and adsorption, effectively recovering and utilizing waste heat from the motor-electronic control system 221 and increasing the pressure on the low-pressure side of the heat pump system. The heat pump circulation loop absorbs high-quality condensation heat from the high-temperature, high-humidity air in the first multimedia heat exchanger 10, which, combined with the waste heat generated by the motor-electronic control system 221, increases the heat quality before supplying heat to the passenger compartment.

[0103] Reference Figure 6 and Figure 7 When the thermal management system 100 is in the third mode, at this time, one of the two first multimedia heat exchangers 10 is in a desorption state, and the other first multimedia heat exchanger 10 is in an adsorption state.

[0104] Reference Figure 6The low-temperature refrigerant at the outlet of the evaporator 241 passes through the seventh multi-way valve 1018 and one of the two sixth multi-way valves 23 into the first refrigerant flow channel 12 of the first multi-media heat exchanger 10 in the adsorption state, and exchanges heat with the first multi-media heat exchanger 10 in the adsorption state. As the internal cold source of the first multi-media heat exchanger 10 in the adsorption state, it takes away the adsorption heat generated by the adsorption process. At the same time, the air flows to the first multi-media heat exchanger 10 in the adsorption state under the drive of the driving fan 60. The moisture in the air is absorbed by the first multi-media heat exchanger 10 in the adsorption state, and the refrigerant leaves the first multi-media heat exchanger 10 after absorbing heat and heating up. The first multi-media heat exchanger 10 in the adsorption state flows into the compressor 242 through the other of the two sixth multi-way valves 23 and the gas-liquid separator 243. After being compressed by the compressor 242, the high-temperature and high-pressure refrigerant enters the third refrigerant flow channel 2232 of the third multi-media heat exchanger 223, and exchanges heat with the coolant in the third coolant flow channel 2231 of the third multi-media heat exchanger 223. After the cooling and pressure reduction, the refrigerant is throttled and reduced in pressure by the second expansion valve 1012, and then enters the evaporator 241 through the second valve body 1014, exchanges heat with the air flowing through the evaporator 241, and evaporates and absorbs the condensation heat generated by water production. After the coolant in the third coolant channel 2231 of the third multi-media heat exchanger 223 absorbs heat and heats up with the refrigerant in the third refrigerant channel 2232 of the third multi-media heat exchanger 223, driven by the second water pump 92, enters the first coolant channel 11 of the first multi-media heat exchanger 10 through the fifth multi-way valve 227 and the other of the two first multi-way valves 21, and serves as an internal heat source to provide the heat required for desorption of the first multi-media heat exchanger 10 switched to the desorption state. Then, the coolant flows back to the third medium heat exchanger through one of the two first multi-way valves 21 to continue the cycle. At the same time, the dry air at the outlet of the first multi-media heat exchanger 10 in the adsorption state flows to the first multi-media heat exchanger 10 in the desorption state, takes away the moisture released by the first multi-media heat exchanger 10 in the desorption state, and then turns into high-temperature and high-humidity air and flows into the evaporation duct of the evaporator 241, exchanges heat with the evaporator 241, so that the high-temperature and high-humidity air is cooled to below the dew point temperature, and liquid water is condensed at the same time to meet the water production demand.

[0105] When the first multi-media heat exchanger 10 in the adsorption state is saturated with adsorption or the first multi-media heat exchanger 10 in the desorption state has completed desorption and water production, the two first multi-way valves 21 and the two sixth multi-way valves 23 are adjusted to allow the coolant to flow through the first multi-media heat exchanger 10 that is saturated with adsorption, so that the first multi-media heat exchanger 10 that is saturated with adsorption can be switched to the desorption state. The refrigerant can flow through the first multi-media heat exchanger 10 that has completed desorption, so that the first multi-media heat exchanger 10 that has completed desorption can be switched to the adsorption state and re-adsorb water vapor (such as Figure 7 The principle is the same as above and will not be described here in detail, so continuous water production is achieved.

[0106] like Figure 6 and Figure 7 It is suitable for when passengers have a need for water production, the humidity of the air outside the equipment or the return air is low, and the equipment is in idle state, there is no coolant waste heat to be recycled, and the heat pump cycle is used to provide high-temperature coolant and low-temperature internal cooling source, while recovering the condensation heat of the first multi-media heat exchanger 10 in the adsorption state to drive the first multi-media heat exchanger 10 to switch to the desorption state.

[0107] like Figure 8 Figure 2 shows a schematic diagram of the single water production mode under high-humidity operating conditions. In this mode, the refrigerant, throttled and cooled by the second expansion valve 1012, enters the evaporator 241 through the second valve body 1014, acting as an internal cooling source to remove the condensation heat from the first multi-media heat exchanger 10 in the adsorption state. Simultaneously, driven by the blower 40, air enters the evaporation channel of the evaporator 241, where it is cooled to below the dew point and produces condensed water, meeting the water production demand. The cooled and dehumidified air leaves the evaporator 241 and enters the third medium heat exchanger. The refrigerant absorbs heat and evaporates, leaving the evaporator 241. It then flows through the seventh multi-way valve 1018 and gas-liquid separator 243 and returns to the compressor 242. After compression by the compressor 242, the high-temperature, high-pressure refrigerant enters the third refrigerant flow channel 2232 of the third multi-media heat exchanger 223, exchanges heat with the cold air at the third medium heat exchanger, and after cooling, flows back into the second expansion valve 1012 to continue the cycle.

[0108] This mode is suitable for fresh air / return air with high humidity. The evaporator 241 is opened, and the third medium heat exchanger is used for heat exchange between the refrigerant and the air. The heat is not dissipated through the second multi-medium heat exchanger 222 outside the equipment. The greater the temperature difference between the low-temperature cold air and the high-temperature refrigerant at the outlet of the evaporator 241, the higher the efficiency is compared with heat exchange with the ambient high-temperature air through the second multi-medium heat exchanger 222 of the equipment.

[0109] Reference Figure 9 and Figure 10 When the thermal management system 100 is in the fourth mode, at this time, one of the two first multimedia heat exchangers 10 is in a desorption state, and the other first multimedia heat exchanger 10 is in an adsorption state.

[0110] Reference Figure 9Driven by the first water pump 91, the high-temperature coolant at the outlet of the motor electronic control system 221 passes through the second multi-way valve 224 and the other of the two first multi-way valves 21 into the first coolant flow channel 11 of the first multi-media heat exchanger 10 in the desorption state, serving as an internal heat source for the first multi-media heat exchanger 10 in the desorption state, providing the heat required for desorption. The low-temperature coolant then flows back to the motor electronic control system 221 through one of the two first multi-way valves 21 and the fourth multi-way valve 226, meeting the cooling needs of the motor electronic control. Simultaneously, in the first air duct 50, driven by the drive fan 60, air flows toward the first multi-media heat exchanger 10 in the desorption state, removes the moisture desorbed by the first multi-media heat exchanger 10 in the desorption state, and is then discharged outside the equipment. Driven by the blower 40, another stream of air flows to the first multimedia heat exchanger 10 in the adsorption state, and its moisture is absorbed by the adsorption part of the first multimedia heat exchanger 10 in the adsorption state to achieve dehumidification of the air. The dehumidified dry air is sent into the cabin to meet the dehumidification requirements.

[0111] When the first multi-media heat exchanger 10 in the adsorption state is saturated with adsorption or the first multi-media heat exchanger 10 in the desorption state has completed desorption and water production, the connection state of the two first multi-way valves 21 and the two sixth multi-way valves 23 is adjusted, and the states of other components remain unchanged, so that the coolant can flow through the first multi-media heat exchanger 10 that is saturated with adsorption, so that the first multi-media heat exchanger 10 that is saturated with adsorption can be switched to the desorption state. The refrigerant can flow through the first multi-media heat exchanger 10 that has completed desorption, so that the first multi-media heat exchanger 10 that has completed desorption can be switched to the adsorption state and re-adsorb water vapor (such as Figure 10 The principle is the same as above and will not be described here again, achieving continuous dehumidification.

[0112] The above mode is applicable to the situation where passengers only have dehumidification needs but no cooling / heating / water production needs, and the coolant temperature at the motor electronic control outlet can enable the first multi-media heat exchanger 10 to switch to the desorption state, and the coolant temperature output by the fourth multi-way valve 226 meets the motor electronic control cooling needs. When the coolant temperature output by the fourth multi-way valve 226 is too high to meet the motor electronic control cooling needs, switch the fourth multi-way valve 226 and the third multi-way valve 225 so that the first multi-media heat exchanger 10 in the desorption state can flow through the second multi-media heat exchanger 222. Turn on the cooling fan 30, and the coolant at the outlet of one of the two first multi-way valves 21 enters the second coolant flow channel 2221 of the second multi-media heat exchanger 222 through the third multi-way valve 225. After heat exchange with the air outside the equipment, the temperature is reduced and flows into the motor electronic control system 221 to cool the motor electronic control (such as Figure 11 shown).

[0113] Reference Figure 12When the thermal management system 100 is in the fifth mode, at this time, one of the two first multimedia heat exchangers 10 is in a desorption state, and the other first multimedia heat exchanger 10 is in an adsorption state.

[0114] like Figure 12 As shown, in this mode, the high-temperature coolant at the outlet of the motor electronic control thermal system passes through the second multi-way valve 224 and the fifth multi-way valve 227 into the third coolant flow channel 2231 of the third multi-media heat exchanger 223, preheating the air flowing through the third multi-media heat exchanger 223. After cooling, the coolant passes through one of the two first multi-way valves 21 and enters the first coolant flow channel 11 of the first multi-media heat exchanger 10 in the desorption state, acting as an internal heat source to provide the heat required for desorption in the first multi-media heat exchanger 10 in the desorption state. This process achieves cascade utilization of coolant waste heat resources. The coolant then passes through the other of the two first multi-way valves 21, the second multi-way valve 224, and the third multi-way valve 225 into the second coolant flow channel 2221 of the second multi-media heat exchanger 222, exchanging heat with the air outside the equipment to cool the coolant. The cooled low-temperature coolant then flows back to the motor electronic control system 221 through the fourth multi-way valve 226, cooling the motor electronic control.

[0115] The high-temperature, high-pressure refrigerant at the outlet of compressor 242 passes through the first solenoid valve and enters the third refrigerant flow channel 2232 of the third multimedia heat exchanger 223, where it exchanges heat with the air. After cooling, the refrigerant is throttled and cooled by the second expansion valve 1012, then passes through the first valve body 1013 and enters the second refrigerant flow channel 2222 of the second multimedia heat exchanger 222. After absorbing heat from the air and coolant outside the equipment, it flows back to compressor 242 through the seventh multi-way valve 1018 and the gas-liquid separator 243. The air in the first air duct 50 flows toward the first multimedia heat exchanger 10, which is in the adsorption state. The air absorbs moisture into the adsorption portion of the first multimedia heat exchanger 10, which is also in the adsorption state, thereby dehumidifying the air. After removing the heat of adsorption and rising in temperature, the dehumidified air enters the second heat exchange duct of the third multimedia heat exchanger 223. Preheated by the high-temperature coolant, it is then heated by the high-temperature refrigerant in the third multimedia heat exchanger 223, transforming into dry, hot air and then being delivered into the cabin, meeting the passenger compartment's heating and dehumidification requirements. Simultaneously, driven by the drive fan 60, the air flows toward the first multimedia heat exchanger 10, which is in a desorption state, removing the moisture desorbed by the first multimedia heat exchanger 10. The air then becomes humid air and is discharged from the equipment.

[0116] When the first multi-media heat exchanger 10 in the adsorption state is saturated with adsorption or the first multi-media heat exchanger 10 in the desorption state has completed desorption and water production, the connectivity of the two first multi-way valves 21 and the two sixth multi-way valves 23 is adjusted, while the states of other components remain unchanged, so that the coolant can flow through the first multi-media heat exchanger 10 that is saturated with adsorption, so that the first multi-media heat exchanger 10 that is saturated with adsorption can be switched to the desorption state. The refrigerant can flow through the first multi-media heat exchanger 10 that has completed desorption, so that the first multi-media heat exchanger 10 that has completed desorption can be switched to the adsorption state and re-adsorb water vapor. The principle is the same as above and will not be repeated here, achieving continuous heating and dehumidification.

[0117] In addition, in the present application, a combination of an evaporator 241, a second multi-media heat exchanger 222, and a third multi-media heat exchanger 223 is used. The evaporator 241 cools the air during water production and cooling, and can recover condensation heat during heating, thereby increasing the pressure on the low-pressure side and reducing the pressure ratio, thereby improving the heating performance of the heat pump system. Under water production conditions, the third multi-media heat exchanger 223 can provide high-temperature coolant as an internal heat source for the first multi-media heat exchanger 10, and the evaporator 241 provides low-temperature refrigerant as an internal cold source, thereby meeting the required heat and cold required for water production without increasing the heating / cooling load of the heat pump system. Under heating conditions, the third multi-media heat exchanger 223 acts as a condenser and a regenerator (recovering waste heat from the coolant), that is, using high-temperature coolant and high-temperature refrigerant to achieve two-stage heating, which can not only meet the low-temperature heating needs, but also fully realize the efficient use of waste heat. The second multi-media heat exchanger 222 allows heat exchange among the coolant, the refrigerant and the air outside the vehicle, thereby achieving the cooling of the coolant and the heat dissipation and heat absorption requirements of the refrigerant.

[0118] Through damper control, the second air duct 70 is connected to the first air duct 50. In certain modes, the low-humidity heated air discharged from the first multi-media heat exchanger 10 during adsorption has an appropriate temperature and humidity, meeting the dehumidification, heating, and ventilation requirements of the passenger compartment. In these modes, the heat pump system is not required; only the fan 60 is required to circulate the airflow, significantly reducing the energy consumption of the thermal management system. This thermal management system 100 can maintain an appropriate temperature for the passenger compartment and power system, and can also regulate the humidity in the passenger compartment for greater comfort.

[0119] The present application adopts a first multi-media heat exchanger 10 which releases adsorption heat while adsorbing moisture in the air, greatly increasing the air temperature and realizing primary heating of the air. The primary heated air is sent to a third multi-media heat exchanger, where it exchanges heat with the coolant and the high-temperature refrigerant in sequence, realizing three-stage heating of the air. The heating demand of the passenger compartment is met through multi-heat source coupling and cascade utilization of energy by recovering waste heat and condensation heat.

[0120] The first multi-media heat exchanger 10 serves as the core dehumidification component. In this thermal management system, both the recycled return air and the newly introduced air first pass through this first multi-media heat exchanger 10. The first multi-media heat exchanger 10 can effectively absorb moisture in the air and release the heat generated during the adsorption process, thereby achieving the dual effects of dehumidification and heating of the air. The air that has been dehumidified and preheated can be directly sent into the vehicle to heat the passenger compartment, or further heated up again through the third multi-media heat exchanger 223 as needed to meet the dehumidification, defogging and heating requirements under different conditions. It is worth noting that the thermal management system of the present application significantly optimizes the energy utilization process, does not need to rely on the intervention of the external circulation, and omits the steps of cooling, dehumidifying and then heating in the traditional method, thereby significantly improving the heating speed and effectively reducing the overall energy consumption of the heat pump system, providing new possibilities for the comfort of the vehicle interior environment and the efficiency of energy utilization in winter.

[0121] It should be noted that condensing air-to-water is based on the dew point principle. When water vapor in the air encounters the condenser surface, which is below its dew point temperature, the water vapor condenses into liquid water while releasing latent heat. Taking the automotive heat pump system as an example, the low-temperature refrigerant in the evaporator in the car evaporates and absorbs heat, and the air flowing through the evaporator is cooled to below the dew point to obtain condensed water. This is called condensing / compressed air-to-water. This technology is more suitable for high-humidity environments, where the air dew point is high and condensation is easy. Otherwise, an extremely low condensing temperature (in the heat pump system, it refers to the evaporation temperature) is required, which consumes a lot of energy, and the evaporator is prone to frost, causing system instability.

[0122] Adsorption-based air-to-water (AWW) technology is based on the adsorption-desorption principle of adsorbent materials. It captures moisture from the air through the adsorbent material, releases it through desorption, and then cools the humid air below its dew point, condensing it to produce liquid water. Compared to condensing-based AWW, this technology significantly raises the air's dew point by enriching water vapor. This eliminates the need for very low evaporation temperatures to produce liquid water, and can meet water production needs at any time under all operating conditions, particularly in arid desert regions and low-temperature, low-humidity environments where condensing-based AWW cannot effectively operate.
