[0002] Thermal management systems are used to heat or cool components in vehicles. As vehicle functions increase, the number of thermally managed objects also increases. Consequently, the number of components within the thermal management system also increases.

[0003] In related technologies, the components of a thermal management system are distributed across different locations within the vehicle. However, as the number of objects requiring thermal management increases, so does the number of components in the thermal management system, resulting in a larger space requirement.

The two ends of the first heat exchange pipe are respectively connected to the heater and the inlet of the second water pump, and the two ends of the second heat exchange pipe are respectively connected to the outlet of the cooler and the seventh interface.

[0018] In one possible implementation, the thermal management system has a second heating mode;

[0029] This disclosure provides a vehicle in which a thermal management system integrates a first water pump, a second water pump, a third water pump, a heater, and a cooler. A multi-way valve controls the connection and disconnection between different water channels on a water plate, enabling the first water pump to cool a first thermally managed object. The second water pump and heater heat a second thermally managed object, and the third water pump and cooler cool a third thermally managed object. Integrating the first, second, and third water pumps and the heater onto a single water plate allows for a more compact structure of the thermally managed object, resulting in a smaller thermal management system size, which facilitates its layout.

[0058] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0060] Thermal management systems are used to heat or cool components in vehicles. As vehicle functions increase, the number of thermally managed objects also increases. Consequently, the number of components within the thermal management system also increases.

[0061] In related technologies, the components of a thermal management system are distributed across different locations within the vehicle. However, as the number of objects requiring thermal management increases, so does the number of components in the thermal management system, resulting in a larger space requirement.

[0062] In view of the above-mentioned technical problems, embodiments of this disclosure provide a thermal management system, such as... Figure 1 and Figure 2As shown, the thermal management system includes a water plate 1, a multi-way valve 2, a first water pump 3, a radiator 4, a second water pump 5, a heater 6, a third water pump 7, and a chiller 8. The multi-way valve 2, the first water pump 3, the second water pump 5, the heater 6, and the third water pump 7 are fixed to the water plate 1. The water plate 1 has a first water channel 11, a second water channel 12, a third water channel 13, a fourth water channel 14, a fifth water channel 15, a sixth water channel 16, a seventh water channel 17, an eighth water channel 18, and a ninth water channel 19. The first water pump 3 is connected to the first water channel 11, the second water pump 5 is connected to the sixth water channel 16, the heater 6 is connected to the fifth water channel 15, and the third water pump 7 is connected to the ninth water channel 19. The multi-way valve 2 has a first port 21, a second port 22, a third port 23, a fourth port 24, a fifth port 25, a sixth port 26, a seventh port 27, and an eighth port 28. First interface 21, first water channel 11, first thermal management object 100, second water channel 12, and second interface 22 are connected in sequence. Third interface 23, third water channel 13, radiator 4, fourth water channel 14, and fourth interface 24 are connected in sequence. Fifth interface 25, fifth water channel 15, second thermal management object 200, sixth water channel 16, and sixth interface 26 are connected in sequence. Seventh interface 27, seventh water channel 17, third thermal management object 300, ninth water channel 19, cooler 8, eighth water channel 18, and eighth interface 28 are connected in sequence.

[0063] The water channels of water plate 1 contain coolant.

[0064] Heater 6 can be a high-voltage electric heater.

[0065] Multiple waterways from the first waterway 11 to the ninth waterway 19 have external interfaces 10 (such as...). Figure 2 (As shown in the black circle in the middle), the external interface 10 is connected to various thermal management objects and components outside the water plate 1 through connecting pipes. The specific positions of each external interface 10 on the water plate 1 can be arranged according to the actual positions of the first thermal management object 100, the second thermal management object 200, and the third thermal management object 300 radiator 4 in the vehicle, so as to make the length of the connecting pipes shorter.

[0066] The technical solution provided in this disclosure integrates a first water pump 3, a second water pump 5, a third water pump 7, a heater 6, and a cooler 8 in the thermal management system. A multi-way valve 2 controls the connection and disconnection between different water channels on the water plate 1, enabling the first water pump 3 to cool the first thermally managed object 100. The second water pump 5 and heater 6 heat the second thermally managed object 200, and the third water pump 7 and cooler 8 cool the third thermally managed object 300. Therefore, the thermal management system can manage the heat of multiple thermally managed objects. Furthermore, the integration of the first water pump 3, second water pump 5, third water pump 7, and heater 6 onto the same water plate 1 makes the thermal management system more compact. This results in a smaller size of the thermal management system, which is beneficial for its placement in a vehicle. It also reduces the cost of the thermal management system (by approximately 10%) and its weight (by approximately 15%).

[0067] In some examples, the thermal management system has a first cooling mode, a first heating mode, and a second cooling mode.

[0068] In the first cooling mode, such as Figure 3 As shown, the first water pump 3 operates, causing coolant to flow through the first thermally managed object 100. This coolant carries away heat from the object, causing its temperature to rise. The second interface 22 and the third interface 23 are connected, allowing the hotter coolant to flow to the radiator 4, where its temperature decreases. The fourth interface 24 is connected to the first interface 21, allowing the cooled coolant to flow back to the first water pump 3 and then through the first thermally managed object 100 again, thus forming a cooling cycle for the object.

[0069] In the first heating mode, such as Figure 4 As shown, the second water pump 5 operates, and the fifth port 25 and the sixth port 26 are connected. This allows the coolant to flow through the multi-way valve 2 to the heater 6, which raises the temperature of the coolant. The heated coolant then flows to the second thermally managed object 200, thereby heating the second thermally managed object 200. After heat exchange with the second thermally managed object 200, the coolant's temperature decreases, and it then flows back through the heater 6. After its temperature rises, it flows back to the second thermally managed object 200, thus forming a heating cycle for the second thermally managed object 200.

[0070] In the second cooling mode, such as Figure 5As shown, the third water pump 7 is operating, and the seventh port 27 and the eighth port 28 are connected. The coolant flows through the refrigerator 8, its temperature decreases, and then flows through the seventh port 27 and the eighth port 28 to the third thermal management object 300, thereby cooling the third thermal management object 300. After heat exchange between the coolant and the third thermal management object 300, the coolant's temperature increases, and it flows through the refrigerator 8 again. After its temperature decreases, it flows through the third thermal management object 300 again, thus forming a cooling cycle for the third thermal management object 300.

[0071] In some examples, the thermal management system also includes a heat exchanger 9. For example... Figure 6 As shown, the heat exchanger 9 includes a first heat exchange pipe 91 and a second heat exchange pipe 92. The two ends of the first heat exchange pipe 91 are connected to the inlets of the heater 6 and the second water pump 5, respectively. One end of the second heat exchange pipe 92 is connected to the outlet of the cooler 8 via the eighth water channel 18, and the other end is connected to the seventh interface 27 via the seventh water channel 17. When the coolant flowing from the heater 6 flows to the first heat exchange pipe 91, and the coolant in the cooler 8 flows to the second heat exchange pipe 92, heat exchange can occur between the first heat exchange pipe 91 and the second heat exchange pipe 92.

[0072] In some examples, the thermal management system has a second heating mode. In the second heating mode, the second water pump 5, the heater 6, and the third water pump 7 operate, and the fifth interface 25 and the sixth interface 26 are connected. Figure 6 As shown, the coolant flowing from the second water pump 5 increases in temperature after passing through the multi-way valve 2 and the heater 6, and then enters the first heat exchange pipe 91 (e.g., Figure 6 (As shown by the dashed arrow). The coolant flowing from the third water pump 7 flows sequentially through the ninth water channel 19 and the eighth water channel 18, and then enters the second heat exchange pipe 92 (as shown by the dashed arrow). Figure 6 (As shown by the solid arrow). After heat exchange between the first heat exchange pipe 91 and the second heat exchange pipe 92, the temperature of the coolant in the second heat exchange pipe 92 rises, and then the coolant flows through the seventh water channel 17 to the third heat management object 300 (e.g., Figure 6 (As shown by the solid arrow in the middle), thereby heating the third heat management object 300.

[0073] Understandably, since the third heat management object is being heated at this time, the cooler 8 is not working, and the seventh port 27 and the eighth port 28 are closed to prevent the cooling water in the eighth water channel 18 from flowing directly to the third heat management object 300 through the seventh water channel 17. This allows more coolant to be heated in the second heat exchange pipe 92, thereby improving the heating effect on the third heat management object 300.

[0074] In some examples, such as Figure 7 and Figure 8As shown, the first water pump 3, the second water pump 5, and the heater 6 are located on the same side of the water plate 1, while the multi-way valve 2, the heat exchanger 9, and the third water pump 7 are located on the other side of the water plate 1. This arrangement allows the components of the thermal management system to be evenly distributed on both sides of the water plate 1, facilitating the layout of various devices and preventing excessive concentration of multiple components.

[0075] In some examples, such as Figure 7 As shown, heater 6 is located between the first water pump 3 and the second water pump 5.

[0076] In some examples, such as Figure 8 As shown, heat exchanger 9 is located between multi-way valve 2 and third water pump 7.

[0077] In some examples, such as Figure 8 and Figure 9 As shown, the thermal management system also includes an expansion tank 400. The multi-way valve 2 also includes a ninth port 29, which is connected to the outlet of the expansion tank 400. The expansion tank 400 can replenish coolant to the multi-way valve 2 through the ninth port 29. It is understood that any two ports in the multi-way valve 2 can be connected; therefore, when any device or water channel needs to be replenished with coolant, simply connect the corresponding port on the multi-way valve 2 to the ninth port 29.

[0078] When the thermal management system is in the first cooling mode, the ninth interface 29 can be connected to the first interface 21, thereby increasing the amount of coolant flowing through the first water pump 3.

[0079] When the thermal management system is in the first heating mode, the ninth interface 29 can be connected to the fifth interface 25, thereby increasing the amount of coolant flowing through the heater 6 and the second thermally managed object 200.

[0080] When the thermal management system is in the second cooling mode, the ninth interface 29 can be connected to the seventh interface 27, thereby increasing the amount of coolant flowing through the third thermal management object 300. Understandably, when there is sufficient coolant in the water plate 1, the ninth interface 29 will close.

[0081] When the thermal management system is in the second heating mode, the ninth interface 29 can be connected to the fifth interface 25, thereby increasing the amount of coolant flowing through the heater 6 and the third thermal management object 300.

[0082] The fifth port 25 of the multi-way valve 2 is connected to the air inlet of the expansion tank 400. It is understood that any two ports in the multi-way valve 2 can be connected; therefore, when any water channel needs to release gas, simply connect the corresponding port on the multi-way valve 2 to the fifth port 25.

[0083] When the thermal management system is in the first cooling mode, the fourth interface 24 and the fifth interface 25 can be connected, allowing the gas in the fourth water channel 14 to enter the expansion tank 400.

[0084] When the thermal management system is in the second cooling mode, the fifth interface 25 can be connected to the seventh interface 27, allowing the gas in the seventh water channel 17 and the eighth water channel 18 to enter the expansion tank 400.

[0085] This reduces the amount of gas in the water plate 1, preventing the gas from affecting the flow of liquid in each water channel, which helps improve the thermal management effect of the thermal management system on each thermally managed object.

[0086] For example, the expansion tank 400 is located at the top of the water plate 1. On the one hand, this facilitates the replenishment of water to the water channels of the water plate 1 by the expansion tank 400. On the other hand, it prevents coolant in the water plate 1 from entering the expansion tank through the air inlet of the expansion tank 400.

[0087] In some examples, such as Figure 10 As shown, the thermal management system also includes two water temperature sensors 500, and the water temperature sensors 500 are fixed to the water plate 1.

[0088] One of the water temperature sensors 500 is located in the seventh water channel 17, and is used to detect the water temperature in the seventh water channel 17. In the second heating mode, if the water temperature sensor 500 detects a high water temperature in the seventh water channel 17, to prevent damage to the third heat management object 300 due to excessively high water temperature, the heater 6 can be turned off, or the speed of the third water pump 7 can be increased. This prevents the water temperature in the second heat exchange pipe 92 from becoming too high, and consequently prevents the water temperature in the seventh water channel 17 from becoming too high.

[0089] Another water temperature sensor 500 is located in the first water channel 11 and is used to detect the water temperature in the first water channel 11. When the water temperature in the first water channel 11 is detected to be low, it indicates that the temperature of the first thermal management object 100 is low and there is no need to cool down the first thermal management object 100. At this time, the first water pump 3 can be turned off.

[0090] This disclosure also provides a vehicle that includes the above-described thermal management system.

[0091] This disclosure does not specifically limit the type of vehicle, such as cars, buses, trucks, sport utility vehicles (SUVs), etc.

[0092] like Figure 10As shown, the first thermal management object 100 in the thermal management system may include an integrated unit of CDU (Conversion & Distribution Unit, DC-DC (Direct Current to Direct Current) converter, OBC (On Board Charger), and high voltage junction box) 1001, F.Motor (Front motor) 1002, and R.Motor (Rear motor) 1003.

[0093] The second thermal management object 200 can be an indoor heater. When the second thermal management object 200 is heated, it can provide heating to the interior of the carriage.

[0094] The third thermal management object 300 may include a Batt (Battery). The thermal management system can heat or cool the third thermal management object 300 so that it can supply power to the vehicle normally.

[0095] The technical solution provided in this disclosure allows for a smaller thermal management system in a vehicle, thus occupying less space and facilitating the arrangement of other components. Furthermore, the fewer components in the thermal management system reduce overall vehicle assembly time (by approximately 60 seconds). Additionally, the lower cost of the thermal management system contributes to a reduction in the overall cost of the vehicle.

[0096] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
