Abstract

[0030] The following is for reference. Figures 1-2 The thermal management system 100 according to an embodiment of the present invention can control the opening and closing of the heat dissipation flow path 1 and the cooling flow path 2 by setting a temperature control valve 3, so as to quickly cool down other components on the vehicle at high temperatures and ensure the reliable operation of other components. At low temperatures, it reduces the possibility of engine self-extinguishing due to condensation generated by the water-cooled intercooler 211 during engine warm-up and can shorten the engine warm-up time. In addition, by setting an expansion tank 4, water can be added to the cooling flow path 2 and venting can be performed to ensure the cooling effect on various components on the vehicle and meet the degassing requirements of the thermal management system 100.
[0031] like Figures 1-2As shown, a thermal management system 100 according to an embodiment of the present invention includes: a heat dissipation flow path 1, a cooling flow path 2, a temperature control valve 3, and an expansion tank 4.
[0032] A radiator 11 is provided in the heat dissipation flow path 1; a cooling module 21 is provided in the cooling flow path 2, and the cooling module 21 includes a water-cooled intercooler 211; a temperature control valve 3 is used to selectively connect the heat dissipation flow path 1 in series with the cooling flow path 2; and an expansion tank 4 is used to replenish water and / or vent air from the cooling flow path 2.
[0033] Specifically, the thermal management system 100 is used to control and regulate the heat generated by the vehicle during operation to ensure that all components can operate stably and efficiently. The thermal management system 100 is provided with a cooling flow path 2 and a heat dissipation flow path 1. Both the cooling flow path 2 and the heat dissipation flow path 1 allow coolant to flow inside them to exchange heat with other components on the vehicle during the flow. A cooling module 21 is provided in the cooling flow path 2. The cooling module 21 is used to allow the coolant to exchange heat with other components on the vehicle at this point to absorb the heat generated by other components during operation and ensure the reliable operation of other components. That is, the coolant can flow along the cooling flow path 2 to the cooling module 21 and absorb heat at the cooling module 21. A radiator 11 is provided in the heat dissipation flow path 1. The radiator 11 is used to allow the coolant to exchange heat with the outside air at this point to release heat. That is, the coolant can flow along the heat dissipation flow path 1 to the radiator 11 and release heat at the radiator 11.
[0034] The coolant can be water or the like, and the cooling module 21 includes a water-cooled intercooler 211. The water-cooled intercooler 211 is used to reduce the intake air temperature of the engine. The water-cooled intercooler 211 is placed in the cooling flow path 2 so that the coolant can flow along the cooling flow path 2 to the water-cooled intercooler 211, where it absorbs heat to reduce the intake air temperature of the engine and improves the reliability of the operation of the water-cooled intercooler 211.
[0035] Furthermore, the thermal management system 100 is also equipped with a temperature control valve 3. The temperature control valve 3 can control the on / off state between the various parts connected to it according to different temperatures. The temperature control valve 3 is used to selectively connect the heat dissipation flow path 1 in series with the cooling flow path 2. That is, both the heat dissipation flow path 1 and the cooling flow path 2 are connected to the temperature control valve 3, so that the temperature control valve 3 can control the on / off state between the heat dissipation flow path 1 and the cooling flow path 2 according to different temperatures. When the heat dissipation flow path 1 and the cooling flow path 2 are connected in series, the coolant in the cooling flow path 2 can enter the heat dissipation flow path 1 to cool down the radiator 11, thereby achieving rapid cooling of other components on the vehicle. When the heat dissipation flow path 1 and the cooling flow path 2 are disconnected, the coolant cannot enter the heat dissipation flow path 1 from the cooling flow path 2. At this time, the heat released by the coolant can be reduced, preventing the water-cooled intercooler 211 from producing condensate during the engine warm-up process, which would cause the engine to self-extinguish. It can also shorten the engine warm-up time and improve user satisfaction.
[0036] Furthermore, the temperature control valve 3 can control the connection and disconnection between the heat dissipation flow path 1 and the cooling flow path 2 according to the different coolant temperatures in the cooling flow path 2. For example, when the coolant temperature in the cooling flow path 2 is higher than 35°C, the temperature control valve 3 can connect the heat dissipation flow path 1 and the cooling flow path 2 to quickly cool down other components on the vehicle and ensure the reliable operation of other components. When the coolant temperature in the cooling flow path 2 is lower than 35°C, the temperature control valve 3 can disconnect the heat dissipation flow path 1 and the cooling flow path 2 to reduce the possibility of the engine self-extinguishing due to condensation generated in the water-cooled intercooler 211 during engine warm-up and to shorten the engine warm-up time.
[0037] Furthermore, the thermal management system 100 is also equipped with an expansion tank 4. The expansion tank 4 has a certain volume and can be used to store coolant. The expansion tank 4 can also play a role in gas-liquid separation to discharge gas in the thermal management system 100, so that the system pressure can be kept stable. Moreover, the expansion tank 4 is used to replenish water and / or vent gas in the cooling flow path 2. The expansion tank 4 can be connected to the cooling flow path 2 so that the coolant in the expansion tank 4 can enter the cooling flow path 2 to replenish water in the cooling flow path 2 when the coolant in the cooling flow path 2 is insufficient. Alternatively, the gas generated in the cooling flow path 2 can enter the expansion tank 4 to vent gas in the cooling flow path 2, so that the system pressure can be kept stable.
[0038] It should be noted that, in this application, the expansion tank 4 can replenish water and vent air from the cooling flow path 2, such as... Figures 1-2 As shown, the temperature control valve 3 is set between the expansion tank 4 and the cooling flow path 2. That is, the temperature control valve 3 can also be used to control the connection between the expansion tank 4 and the cooling flow path 2, so as to add coolant to the cooling flow path 2 when needed and to discharge the gas in the cooling flow path 2.
[0039] According to the thermal management system 100 of this utility model embodiment, the on / off state between the heat dissipation flow path 1 and the cooling flow path 2 can be controlled by setting a temperature control valve 3, so as to quickly cool down other components on the vehicle at high temperatures, ensure the reliable operation of other components, reduce the possibility of engine self-extinguishing due to condensation generated by the water-cooled intercooler 211 during engine warm-up at low temperatures, and shorten the engine warm-up time. In addition, by setting an expansion tank 4, water can be added to the cooling flow path 2 and air can be vented, so as to ensure the cooling effect on various components on the vehicle and meet the degassing requirements of the thermal management system 100.
[0040] In some embodiments, the temperature control valve 3 is provided with a first inlet 31, a second inlet 32, a first outlet 34 and a second outlet 35, a heat dissipation flow path 1 is connected between the first inlet 31 and the first outlet 34, and a cooling flow path 2 is connected between the second inlet 32 and the second outlet 35; wherein, the second inlet 32 is connected to the second outlet 35, or the second inlet 32 is connected to the first outlet 34 and the first inlet 31 is connected to the second outlet 35.
[0041] Specifically, the temperature control valve 3 can be used to control the on / off connection between the heat dissipation flow path 1 and the cooling flow path 2. Connecting the heat dissipation flow path 1 between the first inlet 31 and the first outlet 34 connects both ends of the heat dissipation flow path 1 to the temperature control valve 3, allowing the coolant to flow along the heat dissipation flow path 1 between the radiator 11 and the temperature control valve 3. Connecting the cooling flow path 2 between the second inlet 32 and the second outlet 35 connects both ends of the cooling flow path 2 to the temperature control valve 3, allowing the coolant to flow along the cooling flow path 2 in the water-cooled intercooler 211. The coolant flows between the temperature control valve 3 and the second inlet 32 and the second outlet 35, so that the coolant in the cooling flow path 2 can enter the temperature control valve 3 from the second inlet 32 and then flow to the cooling flow path 2 from the second outlet 35. Through this process, the heat dissipation flow path 1 and the cooling flow path 2 can be disconnected at low temperatures, so that the coolant does not pass through the radiator 11, thereby reducing the heat released by the coolant, preventing the water-cooled intercooler 211 from producing condensate and causing the engine to self-extinguish when the engine is warming up, and shortening the engine warm-up time.
[0042] Alternatively, the second inlet 32 can be connected to the first outlet 34, and the first inlet 31 can be connected to the second outlet 35. This allows the coolant in cooling flow path 2 to enter the temperature control valve 3 from the second inlet 32, then flow from the temperature control valve 3 through the first outlet 34 into the heat dissipation flow path 1, then from the heat dissipation flow path 1 through the first outlet 34 back into the temperature control valve 3, and finally from the temperature control valve 3 through the second outlet 35 back to cooling flow path 2. Through this process, at high temperatures, the heat dissipation flow path 1 and cooling flow path 2 can be connected, allowing the coolant to release heat at the radiator 11 to quickly cool other components on the vehicle, ensuring their reliable operation.
[0043] In some embodiments, the cooling flow path 2 includes a first branch 22 and a second branch 23. The inlet end 221 of the first branch and the inlet end 231 of the second branch are both connected to the second outlet 35. One of the first branch 22 and the second branch 23 is provided with a water-cooled intercooler 211. There are two second inlets 32. The outlet end 222 of the first branch and the outlet end 232 of the second branch are respectively connected to the two second inlets 32.
[0044] Specifically, the cooling flow path 2 allows coolant to flow within it for heat exchange with other components. The cooling flow path 2 includes a first branch 22 and a second branch 23, meaning that both the first branch 22 and the second branch 23 allow coolant to flow within them. The inlet end 221 of the first branch and the inlet end 231 of the second branch are both connected to the second outlet 35, so that the coolant entering the cooling flow path 2 from the second outlet 35 can simultaneously flow to the first branch 22 and the second branch 23 to exchange heat with different components in the first branch 22 and the second branch 23 respectively. Furthermore, one of the first branch 22 and the second branch 23 is equipped with a water-cooled intercooler 211, which can be placed in either the first branch 22 or the second branch 23. This allows the coolant to absorb heat at the water-cooled intercooler 211 when flowing to the first branch 22 and the second branch 23, thereby reducing the intake air temperature of the engine and improving the reliability of the water-cooled intercooler 211.
[0045] Furthermore, there are two second inlets 32. The outlet end 222 of the first branch and the outlet end 232 of the second branch are respectively connected to the two second inlets 32. That is, the first branch 22 and the second branch 23 can be connected to the temperature control valve 3 through one second inlet 32, so that the coolant in the first branch 22 and the second branch 23 can enter the temperature control valve 3, and then mix in the temperature control valve 3 before entering the heat dissipation flow path 1 to release heat at the radiator 11. This can reduce the number of radiators 11 and help reduce the installation cost.
[0046] In some embodiments, the cooling module 21 includes a first power control module 212, an oil cooler 213 and / or a water-cooled intercooler 211 disposed in the first branch 22; and / or, the cooling module 21 includes a driving information and entertainment host 214, a high and low voltage charging system assembly 215 and / or a second power control module 216 disposed in the second branch 23.
[0047] Specifically, the cooling module 21 is used to allow the coolant to absorb heat at this location. The cooling module 21 includes a first power control module 212, an oil cooler 213, and / or a water-cooled intercooler 211, all located in the first branch 22. That is, as the coolant flows along the first branch 22, it can absorb heat at the first power control module 212, the oil cooler 213, and / or the water-cooled intercooler 211, respectively, to ensure the reliable operation of the first power control module 212, the oil cooler 213, and / or the water-cooled intercooler 211. The coolant module 21 also includes a driver information and entertainment host 214, a high and low voltage charging system assembly 215 and / or a second power control module 216 located in the second branch 23. That is, as the coolant flows along the second branch 23, it can absorb heat at the driver information and entertainment host 214, the high and low voltage charging system assembly 215 and / or the second power control module 216 respectively, so as to ensure the reliability of the operation of the driver information and entertainment host 214, the high and low voltage charging system assembly 215 and / or the second power control module 216.
[0048] In such Figures 1-2 In the illustrated embodiment, the first branch 22 is sequentially provided with a first power control module 212, an oil cooler 213, and a water-cooled intercooler 211, meaning that the coolant can absorb heat sequentially at the first power control module 212, the oil cooler 213, and the water-cooled intercooler 211. The second branch 23 is sequentially provided with a driving information and entertainment host 214, a high and low voltage charging system assembly 215, and a second power control module 216, meaning that the coolant can absorb heat sequentially at the driving information and entertainment host 214, the high and low voltage charging system assembly 215, and the second power control module 216, so as to cool down multiple components simultaneously and improve the utilization efficiency of the coolant.
[0049] It should be noted that in actual design, the number of branches in cooling flow path 2 can be increased according to actual needs, and multiple components that need heat dissipation can be set in different branches to cool multiple different components at the same time, which can effectively improve the utilization efficiency of coolant.
[0050] In some embodiments, the cooling flow path 2 further includes a three-way valve 24, which has a first valve port 241, a second valve port 242 and a third valve port 243. The first valve port 241 is connected to the second outlet 35, the second valve port 242 is connected to the inlet end 221 of the first branch, and the third valve port 243 is connected to the inlet end 231 of the second branch.
[0051] Specifically, the three-way valve 24, as a connecting component, serves a connecting function. The three-way valve 24 has a first valve port 241, a second valve port 242, and a third valve port 243, all of which are interconnected. Connecting the first valve port 241 to the second outlet 35 connects the three-way valve 24 to the temperature control valve 3. Connecting the second valve port 242 to the inlet end 221 of the first branch connects the three-way valve 24 to the first branch 22. Thus, the temperature control valve 3 can be connected to the first branch 22 via the three-way valve 24. The connection allows coolant to enter the first branch 22 from the temperature control valve 3 through the three-way valve 24, where it absorbs heat to ensure the reliable operation of all components in the first branch 22. At the same time, connecting the third valve port 243 to the inlet end 231 of the second branch connects the three-way valve 24 to the second branch 23, which in turn connects the temperature control valve 3 to the second branch 23, allowing coolant to enter the second branch 23 from the temperature control valve 3 through the three-way valve 24, where it absorbs heat to ensure the reliable operation of all components in the second branch 23.
[0052] In some embodiments, the thermal management system 100 further includes a water supply branch 5, and the temperature control valve 3 is also provided with a third inlet 33. The expansion tank 4 is connected to the third inlet 33 through the water supply branch 5.
[0053] Specifically, the expansion tank 4 can be used to replenish water and vent air from the cooling flow path 2. The expansion tank 4 is connected to the third inlet 33 through the water replenishment branch 5, so that the coolant in the expansion tank 4 can enter the temperature control valve 3 along the water replenishment branch 5, and then enter the cooling flow path 2 to replenish water to the cooling flow path 2, ensuring the reliability of cooling other components. When the expansion tank 4 is connected to the temperature control valve 3, the gas in the cooling flow path 2 can also enter the temperature control valve 3, and from the temperature control valve 3, enter the expansion tank 4 along the water replenishment branch 5 to vent air from the cooling flow path 2, meeting the degassing requirements of the thermal management system 100.
[0054] In some embodiments, the temperature control valve 3 has two opposite sides, with the third inlet 33, the first inlet 31 and the first outlet 34 all located on one side, and the second inlet 32 and the second outlet 35 all located on the other side.
[0055] Specifically, the two sides of the temperature control valve 3 are set to be opposite to each other, so that different components can be connected to the temperature control valve 3 at the two sides. The third inlet 33, the first inlet 31 and the first outlet 34 are located on one side of the temperature control valve 3, and the second inlet 32 and the second outlet 35 are located on the other side. The heat dissipation flow path 1 is connected between the first inlet 31 and the first outlet 34, and the cooling flow path 2 is connected between the second inlet 32 and the second outlet 35. The heat dissipation flow path 1 and the cooling flow path 2 can be connected to the opposite sides of the temperature control valve 3 respectively, so as to control the opening and closing between the heat dissipation flow path 1 and the cooling flow path 2, ensure the accuracy of the coolant flow direction, and facilitate the coolant to flow in and out from the same side of the temperature control valve 3 at low temperatures.
[0056] In some embodiments, the thermal management system 100 further includes an exhaust branch 6, through which the expansion tank 4 is connected to the water-cooled intercooler 211.
[0057] Specifically, the exhaust branch 6 is used to discharge the gas in the thermal management system 100. The expansion tank 4 is connected to the water-cooled intercooler 211 through the exhaust branch 6, so that the gas in the water-cooled intercooler 211 can enter the expansion tank 4 along the exhaust branch 6. In turn, the gas in the thermal management system 100 can flow from the water-cooled intercooler 211 to the expansion tank 4 along the exhaust branch 6 to discharge the gas in the thermal management system 100 and improve the reliability of the thermal management system 100.
[0058] Therefore, the gas in the thermal management system 100 can enter the expansion tank 4 from the exhaust branch 6 or the water supply branch 5, which improves the reliability of gas entering the expansion tank 4 and the reliability of exhaust of the thermal management system 100, thus meeting the exhaust requirements of the thermal management system 100.
[0059] In some embodiments, the thermal management system 100 further includes a control module, and the cooling flow path 2 is also provided with a water pump 25 and a temperature sensor 26. The control module is electrically connected to the water pump 25, the temperature sensor 26 and the temperature control valve 3 respectively. The control module is used to control the operation of the water pump 25 and the temperature control valve 3 according to the temperature of the temperature sensor 26.
[0060] Specifically, a water pump 25 and a temperature sensor 26 are installed in the cooling flow path 2. The water pump 25 can be used to provide power to the coolant to accelerate its flow, and the temperature sensor 26 can be used to detect the temperature of the coolant. The control module is electrically connected to the water pump 25, the temperature sensor 26 and the temperature control valve 3 respectively, so that the detection result of the temperature sensor 26 can be sent to the control module. In turn, the control module can control the operation of the water pump 25 and the temperature control valve 3 according to the detection result of the temperature sensor 26, so as to change the flow rate of the water pump 25, or make the temperature control valve 3 selectively connect or disconnect the heat dissipation flow path 1 and the cooling flow path 2 to adapt to different temperature requirements.
[0061] And such as Figures 1-2 As shown, a fan 12 is also provided at the radiator 11. The fan 12 is used to accelerate the heat exchange between the coolant and the air. The fan 12 can also be electrically connected to the control module, so that the control module can control the operation of the fan 12 according to the detection result of the temperature sensor 26.
[0062] Furthermore, such as Figure 1 As shown, when the temperature sensor 26 detects that the coolant temperature is higher than 35°C, the control module can control the temperature control valve 3 to connect the heat dissipation flow path 1 and the cooling flow path 2, and can increase the flow rate of the water pump 25 and the speed of the fan 12 to quickly cool down other components on the vehicle and ensure the reliable operation of other components, such as... Figure 2 As shown, when the temperature sensor 26 detects that the coolant temperature is below 35°C, the control module can control the temperature control valve 3 to disconnect the heat dissipation flow path 1 and the cooling flow path 2, and can reduce the flow rate of the water pump 25 and the speed of the fan 12, or stop the fan 12 from rotating, so as to reduce the cooling effect on each component. This can reduce the possibility that the engine will self-extinguish due to the condensation generated by the water-cooled intercooler 211 during the engine warm-up process, and can shorten the engine warm-up time, which is conducive to improving user satisfaction.
[0063] This utility model also proposes a vehicle.
[0064] According to the vehicle of the present utility model embodiment, a thermal management system 100 of any of the above embodiments is provided. By setting a temperature control valve 3, the on / off of the heat dissipation flow path 1 and the cooling flow path 2 can be controlled to quickly cool down other components on the vehicle at high temperatures, ensuring the reliable operation of other components. At low temperatures, the possibility of the engine self-extinguishing due to condensation generated by the water-cooled intercooler 211 during engine warm-up can be reduced, and the engine warm-up time can be shortened. Furthermore, by setting an expansion tank 4, water can be added to the cooling flow path 2 and air can be vented to ensure the cooling effect on various components on the vehicle and to meet the degassing requirements of the thermal management system 100.
