[0052] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0053] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0054] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0055] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0056] like Figures 1 to 4 As shown, according to an embodiment of the present invention, an on-board thermal management system 100 for a vehicle is proposed, the on-board thermal management system 100 including a drinking water system 20 and a compressor system 10.

[0057] The compressor system 10 includes a compressor 11 and a refrigerant circulation path. The refrigerant circulation path is filled with refrigerant. The compressor 11 is installed on the refrigerant circulation path. When the compressor 11 is running, the refrigerant can circulate in the refrigerant circulation path under the drive of the compressor 11.

[0058] The drinking water system 20 includes a cold water assembly, a water tank 201, a water supply component 207, and a hot water assembly. The water tank 201 is used to store drinking water. The cold water assembly includes a first heat exchanger 204, and the hot water assembly includes a second heat exchanger 212.

[0059] The first heat exchanger 204 includes two isolated flow channels, namely the first flow channel and the second flow channel, which can conduct heat to each other. The first flow channel is connected to the refrigerant circulation flow path and the connection point is located at the inlet side of the compressor 11. The water tank 201 is connected to the water supply component 207 through the second flow channel. The refrigerant in the refrigerant circulation flow path can flow through the first flow channel, and the drinking water stored in the water tank 201 flows to the water supply component 207 through the second flow channel.

[0060] The second heat exchanger 212 includes two isolated flow channels, namely the third flow channel and the fourth flow channel, which can conduct heat to each other. The third flow channel is connected to the refrigerant circulation flow path and the connection point is located on the outlet side of the compressor 11. The water tank 201 is connected to the water supply component 207 through the fourth flow channel. The refrigerant in the refrigerant circulation flow path can flow through the third flow channel, and the drinking water stored in the water tank 201 flows to the water supply component 207 through the fourth flow channel.

[0061] It's important to understand that the heat conduction arrangement between the first and second flow channels means that when refrigerant flows through the first flow channel and drinking water flows through the second flow channel, the refrigerant in the first flow channel can exchange heat with the drinking water in the second flow channel. Similarly, the heat conduction arrangement between the third and fourth flow channels means that when refrigerant flows through the third flow channel and drinking water flows through the fourth flow channel, the refrigerant in the third flow channel can exchange heat with the drinking water in the fourth flow channel.

[0062] In addition, in the compressor system 10, the compressor 11 provides power for the refrigerant to circulate in the refrigerant circulation path. At the inlet side of the compressor 11, the refrigerant is a low-temperature and low-pressure refrigerant. The drinking water flowing through the second flow channel is cooled by exchanging heat with the refrigerant. At the outlet side of the compressor 11, the refrigerant is a high-temperature and high-pressure refrigerant. The drinking water flowing through the fourth flow channel is heated by exchanging heat with the refrigerant.

[0063] Furthermore, in this application, the drinking water in the water tank 201 can selectively flow to the water supply component 207 through at least one of the second flow channel and the fourth flow channel, which means that the drinking water in the water tank 201 flows to the water supply component 207 only through the second flow channel, or the drinking water in the water tank 201 flows to the water supply component 207 only through the fourth flow channel, or the drinking water in the water tank 201 flows to the water supply component 207 simultaneously through both the second flow channel and the fourth flow channel.

[0064] According to the vehicle thermal management system 100 of the present invention, when the compressor system 10 is running, the first heat exchanger 204 is connected to the inlet side of the compressor 11, and the second heat exchanger 212 is connected to the outlet side of the compressor 11. Low-temperature refrigerant flows into the inlet of the compressor 11, and high-temperature refrigerant flows out from the outlet side of the compressor 11. The low-temperature refrigerant at the inlet side of the compressor 11 is used to cool the drinking water flowing through the second channel, while the high-temperature refrigerant at the outlet side of the compressor 11 is used to heat the drinking water flowing through the fourth channel. According to the needs of the driver and passengers, the cold water in the cold water assembly, the hot water in the hot water assembly, or the warm water formed by mixing the cold water in the cold water assembly and the hot water in the hot water assembly in a certain proportion is selected and output through the water supply component 207 to meet the various drinking water needs of the driver and passengers, thereby improving the user experience.

[0065] It should be noted that in this application, the compressor system 10 can be the vehicle's air conditioning compressor system or the vehicle's refrigerator compressor system. The water system is effectively adapted to the compressor system 10, thereby using the compressor system 10 to provide energy for heating and cooling the drinking water in the water system, thereby reducing the energy consumption required by the water system and increasing the vehicle's range.

[0066] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the cold water assembly also includes a first pipe 203 connecting the water tank 201 and the water supply component 207. A first heat exchanger 204 is disposed on the first pipe 203, and the second flow channel of the first heat exchanger 204 is connected to the first pipe 203. When the drinking water in the water tank 201 flows to the water supply component 207 through the first pipe 203, the drinking water in the first pipe 203 flows through the second channel of the first heat exchanger 204.

[0067] In this application, the connection between the first pipe 203 and the water tank 201 is located at the bottom of the water tank 201, so that the drinking water in the water tank 201 can enter the first pipe 203 under its own gravity, thereby improving the convenience of drinking water flowing from the water tank 201 into the first pipe 203.

[0068] The hot water assembly also includes a second pipeline connecting the water tank 201 and the water supply component 207. A second heat exchanger 212 is disposed on the second pipeline, and the fourth flow channel of the second heat exchanger 212 is connected to the second pipeline. When drinking water in the water tank 201 flows to the water supply component 207 through the second pipeline, the drinking water in the second pipeline flows through the fourth channel of the second heat exchanger 212.

[0069] In this application, the connection point between the second pipeline and the water tank 201 is located at the bottom of the water tank 201, so that the drinking water in the water tank 201 can enter the second pipeline under its own gravity, thereby improving the convenience of drinking water flowing from the water tank 201 into the second pipeline.

[0070] The vehicle-mounted drinking water supply system also includes a regulating component, wherein the regulating component is provided on at least one of the first pipe 203 and the second pipe, and the regulating component is used to regulate the flow path of the pipe.

[0071] In this application, by providing an adjustment component on at least one of the first pipeline 203 and the second pipeline, the flow rate of the pipeline is adjusted by the adjustment component. By adjusting the flow rate of the pipeline, the ratio of drinking water mixed in the first pipeline 203 and the second pipeline to the water supply unit 207 is adjusted, thereby achieving the adjustment of the drinking water temperature and effectively meeting the usage needs of drivers and passengers.

[0072] It is important to understand that when passengers need drinking water at a lower temperature, the flow rate of the first pipe 203 is increased using the regulating component; conversely, when passengers need drinking water at a higher temperature, the flow rate of the first pipe 203 is increased using the regulating component.

[0073] The regulating component can be installed only on the first pipe 203, or only on the second pipe, or both the first pipe 203 and the second pipe can be installed.

[0074] The following explanation uses the example of adjusting components being installed on both the first pipe 203 and the second pipe as an example:

[0075] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the regulating assembly includes a first regulating valve 206 and a second regulating valve 208. The first regulating valve 206 is disposed on the first pipeline 203, and the flow rate of the first pipeline 203 is regulated by the first regulating valve 206. The second regulating valve 208 is disposed on the second pipeline, and the flow rate of the second pipeline is regulated by the second regulating valve 208.

[0076] Specifically, a first regulating valve 206 is installed on the first pipeline 203, and a second regulating valve 208 is installed on the second pipeline. The first regulating valve 206 regulates the flow rate of the first pipeline 203, and the second regulating valve 208 regulates the flow rate of the second pipeline. When the required drinking water temperature is less than or equal to the temperature of the drinking water in the first pipeline 203, the second regulating valve 208 is closed and the first regulating valve 206 is opened, allowing cold water to be supplied to the occupants through the water supply component 207. When the required drinking water temperature is greater than or equal to the temperature of the drinking water in the second pipeline, the first regulating valve 206 is closed and the second regulating valve 208 is opened, allowing hot water to be supplied to the occupants through the water supply component 207. When the required drinking water temperature is greater than the temperature of the drinking water in the first pipeline 203 but less than the temperature of the drinking water in the second pipeline, the opening degrees of the first regulating valve 206 and the second regulating valve 208 are adjusted respectively to ensure that the drinking water flowing out of the water supply component 207 meets the drinking needs of the occupants.

[0077] It should be understood that the first regulating valve 206 is used to regulate the flow rate of the first pipeline 203. The regulation range of the first regulating valve 206 is between 0 and the maximum opening. When the opening of the first regulating valve 206 is 0, the first pipeline 203 is in a cut-off state, and the drinking water in the water tank 201 cannot flow to the water supply component 207 through the first pipeline 203. When the opening of the first regulating valve 206 reaches the maximum, the first regulating valve 206 is in a fully open state, and the first pipeline 203 reaches the maximum flow rate.

[0078] Similarly, the second regulating valve 208 is used to regulate the flow rate of the second pipeline. The regulation range of the second regulating valve 208 is between 0 and the maximum opening. When the opening of the second regulating valve 208 is 0, the second pipeline is in a cut-off state, and the drinking water in the water tank 201 cannot flow to the water supply component 207 through the second pipeline. When the opening of the second regulating valve 208 reaches the maximum, the second regulating valve 208 is in a fully open state, and the second pipeline reaches the maximum flow rate.

[0079] It should be noted that the first regulating valve 206 can be a manual regulating structure or an electronically controlled regulating structure. Similarly, the second regulating valve 208 can be a manual regulating structure or an electronically controlled regulating structure.

[0080] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the regulating component also includes a first temperature sensor 205 and a second temperature sensor 209. The first temperature sensor 205 is disposed on the first pipe 203 and detects the water temperature in the first pipe 203. The second temperature sensor 209 is disposed on the second pipe and detects the water temperature in the second pipe.

[0081] Specifically, by setting a first temperature detection element 205, the temperature of drinking water in the first pipeline 203 can be obtained in real time. By setting a second temperature detection element 209, the temperature of drinking water in the second pipeline can be obtained in real time. By detecting the temperature of drinking water in the first pipeline 203 and the second pipeline, the opening degree of the first regulating valve 206 and the second regulating valve 208 can be controlled according to the temperature, so that the drinking water output through the water supply element 207 meets the usage needs of drivers and passengers.

[0082] It should be noted that in this application, the first temperature detection element 205 can be a temperature sensor or thermometer, and similarly, the second temperature detection element 209 can also be a temperature sensor or thermometer.

[0083] Furthermore, in this application, both the first regulating valve 206 and the second regulating valve 208 are positioned close to the water supply component 207. The first temperature sensor 205 is positioned between the first regulating valve 206 and the first heat exchange component 204, and is positioned close to the first regulating valve 206. The second temperature sensor 209 is positioned between the second regulating valve 208 and the second heat exchange component 212, and is positioned close to the second regulating valve 208. By configuring the first regulating valve 206, the second regulating valve 208, the first temperature sensor 205, and the second temperature sensor 209, the temperatures detected by the first temperature sensor 205 and the second temperature sensor 209 are positioned closer to the water supply component 207, thereby reducing heat loss of drinking water during its flow along the pipeline and improving the accuracy of temperature control.

[0084] In some embodiments of the present invention, the vehicle thermal management system 100 further includes a control device, which is electrically connected to the water supply component 207, the compressor 11 and the regulating component.

[0085] Specifically, a control device is installed to control the vehicle control system, thereby enabling automatic control and improving the convenience of use.

[0086] It should be noted that in this application, the vehicle thermal management system 100 also includes a human-machine interface device (a combination of a button panel and a display screen, or a touch screen, etc.). The human-machine interface device is electrically connected to the control device. The driver and passengers input the desired drinking water temperature in the human-machine interface device, and the human-machine interface device feeds back the desired drinking water temperature to the control device. Based on the desired drinking water temperature, the drinking water temperature in the first pipeline 203 detected by the first temperature detector 205, and the drinking water temperature in the second pipeline detected by the second temperature detector 209, the control device controls the first regulating valve 206 and the second regulating valve 208, so that the temperature of the drinking water output through the water supply device 207 meets the drinking needs of the driver and passengers.

[0087] In addition, the water supply component 207 is also controlled by a control device, which controls the opening or closing of the water supply component 207. In this application, the water supply component 207 is a component such as a solenoid valve.

[0088] In addition, the control device can be an independent control device for the vehicle thermal management system 100, or it can be a general control device for the vehicle.

[0089] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the cold water assembly also includes a first water pump 202, which is installed on the first pipeline 203, and the control device is electrically connected to the first water pump 202.

[0090] A first water pump 202 is installed to provide power for drinking water to flow from the water tank 201 along the first pipeline 203 to the water outlet, thereby increasing the flow rate of drinking water, improving the efficiency of external water supply, reducing the waiting time for drivers and passengers, and thus improving the user experience of drivers and passengers.

[0091] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the hot water assembly also includes a second water pump 211, which is installed on the second pipeline, and the control device is electrically connected to the first water pump 202.

[0092] A second water pump 211 is installed to provide power for drinking water to flow from the water tank 201 along the second pipeline to the water outlet, thereby increasing the flow rate of drinking water, improving the efficiency of external water supply, reducing the waiting time for drivers and passengers, and thus improving the user experience of drivers and passengers.

[0093] In some embodiments of the present invention, the hot water assembly further includes a heating element 210, which is disposed on the second pipeline and is electrically connected to a control device for heating the passing drinking water.

[0094] Specifically, the heating element 210 is installed on the second pipeline. The heat generated by the heating element 210 during operation can be transferred to the interior of the second pipeline. When drinking water passes through the location of the heating element 210, the heating element 210 can heat the drinking water to raise its temperature. By installing the heating element 210 and using its operation to further heat the drinking water in the second pipeline, the temperature of the drinking water can be further increased, thus further meeting the usage needs of drivers and passengers.

[0095] It is important to understand that when the drinking water in the water tank 201 flows through the fourth channel of the second heat exchanger 212, the refrigerant from the compressor system 10 heats the drinking water through the heat conduction arrangement of the third and fourth channels of the second heat exchanger 212. When the heated temperature is lower than the drinking water temperature required by the occupants, the control device controls the heating element 210 to operate, using the heating element 210 to further heat the drinking water to meet the drinking needs of the occupants.

[0096] In addition, the heating element 210 can heat drinking water to boiling, thereby meeting the user's need for boiled water.

[0097] It should be noted that, in this application, the heating element 210 includes, but is not limited to, components such as heating wires or heating rods.

[0098] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the compressor system 10 also includes an evaporator 13 and a condenser 16, wherein the evaporator 13 and the condenser 16 are connected in series in the refrigerant circulation path.

[0099] The first heat exchanger 204 has two installation methods. One method is that the first heat exchanger 204 is connected in series between the inlet side of the evaporator 13 and the compressor 11. The other method is that the evaporator 13 and the first heat exchanger 204 are connected in parallel.

[0100] The second heat exchanger 212 also has two installation methods. One installation method is that the second heat exchanger 212 is connected in series between the outlet side of the condenser 16 and the compressor 11. The other method is that the condenser and the second heat exchanger 212 are connected in parallel.

[0101] Specifically, such as Figure 1 and Figure 2As shown, when the first heat exchanger 204 is connected in series with the evaporator 13, the outlet end of the evaporator 13 is connected to the first heat exchanger 204, and the evaporator 13 is connected to the first flow channel of the first heat exchanger 204. The inlet side of the compressor 11 is connected to the first heat exchanger 204, and the inlet side of the compressor 11 is connected to the first flow channel. Connecting the first heat exchanger 204 in series in the refrigerant circulation path improves the convenience of the assembly process.

[0102] like Figure 1 and Figure 2 As shown, when the second heat exchanger 212 is connected in series with the condenser 16, the inlet end of the condenser 16 is connected to the second heat exchanger 212, and the condenser 16 is connected to the third flow channel of the second heat exchanger 212. The outlet side of the compressor 11 is connected to the second heat exchanger 212, and the outlet side of the compressor 11 is connected to the third flow channel. Connecting the second heat exchanger 212 in series in the refrigerant circulation path improves the convenience of the assembly process.

[0103] like Figure 3 As shown, when the first heat exchanger 204 is connected in parallel with the evaporator 13, one end of the first heat exchanger 204 is connected in parallel with the inlet end of the evaporator 13, and the other end of the first heat exchanger 204 is connected in parallel with the outlet end of the evaporator 13. Connecting the first heat exchanger 204 in series in the refrigerant circulation path improves the compactness of the structure.

[0104] like Figure 3 As shown, when the second heat exchanger 212 is connected in parallel with the condenser 16, one end of the second heat exchanger 212 is connected in parallel with the inlet end of the condenser 16, and the other end of the second heat exchanger 212 is connected in parallel with the outlet end of the condenser 16. Connecting the second heat exchanger 212 in series in the refrigerant circulation path improves the compactness of the structure.

[0105] It should be noted that, in this application, if Figures 1 to 3 As shown, the compressor system 10 also includes a gas-liquid separator 12, a first fan 14, a second fan 17, and a throttling element 15. The gas-liquid separator 12 and the throttling element 15 (e.g., an electronic expansion valve) are connected in series in the refrigerant circulation path. The gas-liquid separator 12 is disposed between the first heat exchanger 204 and the compressor 11, and the throttling element 15 is disposed between the condenser 16 and the evaporator 13.

[0106] The first fan 14 is arranged adjacent to the first heat exchanger 204. The first fan 14 drives the airflow to exchange heat with the first heat exchanger 204 so that the first heat exchanger 204 can cool the airflow and use the cooled airflow to cool the vehicle's passenger space or the vehicle refrigerator.

[0107] The second fan 17 is arranged adjacent to the second heat exchanger 212. The second fan 17 drives the airflow to exchange heat with the second heat exchanger 212, so as to cool down the second heat exchanger 212.

[0108] In some embodiments of the present invention, such as Figure 1 or Figure 3 As shown, the first heat exchanger 204 includes a first heat exchange body, and a first flow channel and a second flow channel are respectively formed on the first heat exchange body.

[0109] Specifically, in this application, the first heat exchanger 204 is an integral structure, and the first flow channel and the second flow channel are respectively formed on the first heat exchanger 204. The first flow channel and the second flow channel are heat-conductingly arranged. By making the first heat exchanger 204 an integral structure, the thermal resistance between the first flow channel and the second flow channel is reduced, and the heat exchange efficiency between the first flow channel and the second flow channel is improved. In addition, making the first heat exchanger 204 an integral structure reduces the assembly process and can effectively improve the assembly efficiency.

[0110] In some embodiments of the present invention, such as Figure 1 or Figure 3 As shown, the second heat exchanger 212 includes a second heat exchange body, and a third flow channel and a fourth flow channel are respectively formed on the second heat exchange body.

[0111] Specifically, in this application, the second heat exchanger 212 is an integral structure, and the third and fourth flow channels are respectively formed on the second heat exchanger 212. The third and fourth flow channels are heat-conductingly arranged. By making the second heat exchanger 212 an integral structure, the thermal resistance between the third and fourth flow channels is reduced, and the heat exchange efficiency between the third and fourth flow channels is improved. In addition, making the second heat exchanger 212 an integral structure reduces the assembly process and can effectively improve the assembly efficiency.

[0112] In some embodiments of the present invention, such as Figure 2 As shown, the first heat exchanger 204 includes a first part and a second part, the first part and the second part are thermally connected, a first flow channel is formed on the first part, and a second flow channel is formed on the second part.

[0113] Specifically, in this application, the first heat exchanger 204 is a split structure, with the first flow channel and the second flow channel respectively opened on the first part and the second part. By setting the first heat exchanger 204 as a split structure, the processing difficulty of the first heat exchanger 204 is reduced.

[0114] It should be noted that the first part and the second part are connected to each other, and the connection method includes, but is not limited to, bonding, welding or connection via connectors.

[0115] In some embodiments of the present invention, such as Figure 2 As shown, the second heat exchanger 212 includes a third part and a fourth part, the third part and the fourth part are thermally connected, the third flow channel is opened on the third part, and the fourth flow channel is opened on the fourth part.

[0116] Specifically, in this application, the second heat exchanger 212 is a split structure, with the third flow channel and the fourth flow channel respectively opened on the third and fourth parts. By setting the second heat exchanger 212 as a split structure, the processing difficulty of the second heat exchanger 212 is reduced.

[0117] It should be noted that the third and fourth parts are connected to each other, and the connection methods include, but are not limited to, bonding, welding or connection via connectors.

[0118] like Figures 1 to 3 As shown, the second aspect of this application proposes a control method for an on-board thermal management system 100. The control method for the on-board thermal management system 100 is implemented based on the above-described on-board thermal management system 100 and includes:

[0119] S10: Controls the operation of compressor system 10.

[0120] Specifically, in this application, when the water supply system supplies water to the outside, the compressor system 10 needs to be in operation, and the compressor system 10 is used to heat and cool the drinking water respectively, so as to meet the needs of drivers and passengers through the heated and cooled drinking water.

[0121] The compressor system 10 can be a compressor system for a vehicle refrigerator or a compressor system for a vehicle air conditioner. As a preferred embodiment, in this application, the compressor system 10 is a compressor system for a vehicle refrigerator. Since the vehicle compressor system 10 is usually on, the frequency of starting and stopping the compressor system 10 can be reduced, thereby reducing the failure rate of the compressor system 10. At the same time, the compressor system 10 of the vehicle refrigerator has low energy consumption, which can reduce energy waste and effectively reduce the operating costs of the vehicle.

[0122] S20: Obtain the target temperature of drinking water, the first temperature on the output side of the first heat exchanger 204, and the second temperature on the output side of the second heat exchanger 212.

[0123] Specifically, when passengers need drinking water, they input the target temperature of the drinking water to the control device through the human-machine interface. The control device receives the target temperature of the drinking water and simultaneously receives the first temperature of the drinking water in the first pipeline 203 detected by the first temperature detector 205 (i.e., the first temperature on the output side of the first heat exchanger 204). The control device also simultaneously receives the second temperature of the drinking water in the second pipeline detected by the second temperature detector 209 (i.e., the second temperature on the output side of the second heat exchanger 212). The control device controls the regulating component according to the target temperature, the first temperature, and the second temperature so that the temperature of the drinking water output through the water supply component 207 meets the drinking needs of the passengers.

[0124] It should be noted that in this application, a third temperature detection element is provided inside the water tank 201. The third temperature detection element is electrically connected to the control device and is used to detect the temperature of the drinking water inside the water tank 201. The drinking water supplied by the water supply element 207 at one time is a fixed quantity. The target temperature and the water supply volume are related.

[0125] S30: Based on the target temperature being greater than the first temperature and less than the second temperature, control the opening of the first regulating valve 206 of the cold water component and the second regulating valve 208 of the hot water component so that the drinking water output by the water supply component 207 reaches the target temperature.

[0126] Specifically, the control device compares the target temperature with the first temperature and the second temperature respectively. When the target temperature is greater than the first temperature and less than the second temperature, the control device controls the first regulating valve 206 and the second regulating valve 208 to open respectively. There is a temperature difference between the target temperature and the current temperature of the drinking water (cold water supplied by the cold water component and hot water supplied by the hot water component). The flow rate is inversely proportional to the temperature difference, that is, the opening of the regulating valve is large when the temperature difference is small, and the opening of the regulating valve is small when the temperature difference is large. By effectively controlling the opening of the first regulating valve 206 and the second regulating valve 208, the drinking water output through the water supply component 207 reaches the target temperature, thereby meeting the drinking needs of the drivers and passengers.

[0127] S40: Based on the target temperature being equal to the first temperature, control the second regulating valve 208 to close.

[0128] Specifically, when the target temperature of the drinking water required by the driver and passengers is equal to the first temperature, the cold water output by the cold water component can meet the needs of the driver and passengers. Therefore, the control device controls the second regulating valve 208 to close and controls the first regulating valve 206 to open, so that the drinking water in the hot water component can be supplied to the driver and passengers through the water supply component 207, thereby meeting the drinking needs of the driver and passengers.

[0129] S50: Based on the target temperature being equal to the second temperature, control the first regulating valve 206 to close.

[0130] Specifically, when the target temperature of the drinking water required by the driver and passengers is equal to the second temperature, the hot water output by the hot water unit can meet the needs of the driver and passengers. Therefore, the control device controls the first regulating valve 206 to close and the second regulating valve 208 to open, so that the drinking water in the hot water unit can be supplied to the driver and passengers through the water supply component 207, thereby meeting the drinking needs of the driver and passengers.

[0131] S60: Based on the target temperature being greater than the second temperature, control the first regulating valve 206 to close and control the heating element 210 of the hot water assembly to operate.

[0132] Specifically, when the target temperature of the drinking water required by the driver and passengers is greater than the second temperature, the hot water output by the hot water unit cannot meet the needs of the driver and passengers. Therefore, the control device controls the first regulating valve 206 to close and the second regulating valve 208 to open, and controls the heating element 210 to operate, so that the drinking water in the hot water unit is supplied to the driver and passengers through the water supply element 207, thereby meeting the drinking needs of the driver and passengers.

[0133] It should be noted that when the target temperature is greater than the second temperature, the heat required for the hot water supplied by the hot water unit to reach the target temperature is provided by the heating element 210. According to the heat formula Q=cρvΔt, where Q is the heat, c is the specific heat capacity of water, ρ is the density of water, v is the volume of water (the volume of drinking water required), and Δt is the temperature difference between the second temperature and the target temperature, the heating power of the heating element 210 is controlled to make the drinking water reach the target temperature.

[0134] According to the control method of the vehicle thermal management system 100 of the present invention, when the compressor system 10 is running, the first heat exchanger 204 is connected to the inlet side of the compressor 11, and the second heat exchanger 212 is connected to the outlet side of the compressor 11. Low-temperature refrigerant flows into the inlet of the compressor 11, and high-temperature refrigerant flows out from the outlet side of the compressor 11. The low-temperature refrigerant at the inlet side of the compressor 11 is used to cool the drinking water flowing through the second channel, while the high-temperature refrigerant at the outlet side of the compressor 11 is used to heat the drinking water flowing through the fourth channel. According to the needs of the driver and passengers, the cold water in the cold water assembly, the hot water in the hot water assembly, or the warm water formed by mixing the cold water in the cold water assembly and the hot water in the hot water assembly in proportion is selected and output through the water supply component 207 to meet the various drinking water needs of the driver and passengers, thereby improving the user experience.

[0135] A third aspect of the present invention provides a vehicle comprising the on-board thermal management system 100 as described above.

[0136] According to the vehicle of the present invention, when the compressor system 10 is running, the first heat exchanger 204 is connected to the inlet side of the compressor 11, and the second heat exchanger 212 is connected to the outlet side of the compressor 11. Low-temperature refrigerant flows into the inlet of the compressor 11, and high-temperature refrigerant flows out from the outlet side of the compressor 11. The low-temperature refrigerant at the inlet side of the compressor 11 is used to cool the drinking water flowing through the second channel, while the high-temperature refrigerant at the outlet side of the compressor 11 is used to heat the drinking water flowing through the fourth channel. According to the needs of the driver and passengers, the cold water in the cold water assembly, the hot water in the hot water assembly, or the warm water formed by the proportional mixing of the cold water in the cold water assembly and the hot water in the hot water assembly can be selected and output through the water supply component 207 to meet the various drinking water needs of the driver and passengers, thereby improving the user experience.

[0137] In this invention, the structure of other parts of the vehicle described above is described in reference to the prior art, and will not be repeated here.

[0138] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
