Abstract
Description
Technical Field
[0001] The present invention relates to a thermal management system for a vehicle, and more specifically, to a thermal management system for a vehicle configured to perform thermal management of the vehicle’s passenger space, electrical components and high-voltage battery, said vehicle comprising a first body having the passenger space and a second body combined with the first body to define the vehicle as a whole. Background Technology
[0002] In recent years, due to the environmental impact of internal combustion engine vehicles, the trend has been towards the widespread adoption of electric vehicles as an environmentally friendly option. Conventional internal combustion engine vehicles can utilize the waste heat generated by the engine to heat the vehicle's interior, thus eliminating the need for additional energy for heating the cabin. However, electric vehicles, lacking an engine to act as a heat source, must utilize additional energy to heat the interior, increasing energy consumption. This reduces the driving range of electric vehicles, leading to more frequent battery charging, which is problematic.
[0003] With the electrification of vehicles, there is a growing need for thermal management of electrical components such as high-voltage batteries and motors, as well as the vehicle's interior space. Specifically, in electric vehicles, the interior space, batteries, and electrical components have different air conditioning requirements. Therefore, a technology is needed that can independently respond to these different requirements and effectively coordinate them to achieve maximum energy savings. Accordingly, the concept of integrated vehicle thermal management has been proposed, which can improve heating efficiency by performing independent thermal management on individual vehicle components and by performing overall thermal management in an integrated manner.
[0004] Recently, the concept of a vehicle consisting of a first body and a second body has been proposed. The first body can be widely used in various vehicles, and the second body is combined with the first body to form a complete vehicle. Specifically, in order to form a complete vehicle body for an electric vehicle, the first body and the second body are combined with each other. The first body is equipped with electrical components, batteries, etc., which are commonly used in electric vehicles, and the second body defines the passenger space and is combined with the first body to form a complete vehicle.
[0005] To date, proposed vehicle thermal management systems only address vehicles where the interior space, electrical components, and battery are housed within a single vehicle body. Therefore, there is a need to develop a thermal management system applicable to vehicles of this type, which consist of a first body and a second body.

[0044] In the following description, exemplary embodiments of the invention will be illustrated with reference to the accompanying drawings. Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will be further understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having the same meaning as they have in the context of the prior art and the present invention, and should not be interpreted in an idealized or overly formal sense unless explicitly defined herein.
[0045] The specific structural and functional descriptions of the embodiments of the present invention disclosed herein are for illustrative purposes only and are not intended to represent the entire technical spirit of the invention. Rather, the invention is intended to cover not only the exemplary embodiments but also various alternative, modified, equivalent, or other embodiments, which are included within the spirit and scope of the invention as defined by the appended claims.
[0046] In the following text, reference will be made to Figure 1 The overall construction of a vehicle thermal management system according to a first exemplary embodiment of the present invention will be described, and reference will be made to 2 to 3. Figure 12 The operation of the thermal management system of a vehicle according to a first exemplary embodiment of the present invention, as well as the flow of refrigerant and coolant, is described.
[0047] refer to Figure 1 According to a first exemplary embodiment of the present invention, the vehicle thermal management system may include an in-vehicle air conditioner 100 and a component air conditioner 200.
[0048] An in-vehicle air conditioner 100 is installed in a first body 10 having a passenger space. The in-vehicle air conditioner 100 may include a compressor 110, a first condenser 120, an evaporator 130, and a refrigerant line 140 circulating refrigerant. Air from a fan 150 passing through the evaporator 130 can be supplied to the passenger space.
[0049] The in-vehicle air conditioning 100 may further include: a first flow path 160, a second flow path 170, a first valve 180, and an electric heater 190. Air from the fan 150 passing through the evaporator 130 is discharged through the first flow path 160. The second flow path 170 is located below the first flow path 160, and its outlet portion converges with the outlet portion of the first flow path 160. The first valve 180 is arranged between the first condenser 120 and the evaporator 130. The electric heater 190 is used to heat the air supplied to the passenger space.
[0050] Additionally, the vehicle air conditioning 100 may further include: a first damper 193 and a first damper actuator 194, wherein the first damper 193 is configured to selectively close either the first flow path 160 or the second flow path 170, or open both the first flow path 160 and the second flow path 170; and the first damper actuator 194 is used to drive the first damper 193.
[0051] A component air conditioner 200 is disposed at a second body 20, which is combined with a first body 10 to form a vehicle body. Furthermore, the component air conditioner 200 includes: an electrical component line 220 for cooling vehicle components 210; and a first battery line 240 for cooling a high-voltage battery 230. Here, the first battery line 240 includes a cooler 250. Figure 1 As shown, when the first body 10 is coupled to the second body 20, the cooler 250 extends at its end to the first body 10 so as to be located behind the first body. More specifically, the end of the cooler 250 may be located in the second flow path 170. In an exemplary embodiment, the cooler 250 may include an air-cooled cooler.
[0052] As described above, according to an exemplary embodiment of the present invention, since the end of the cooler 250 is arranged behind the evaporator 130, the air passing through the evaporator 130 enters a flow path communicating with the passenger space, thereby allowing the air passing through the evaporator 130 to exchange heat with the end of the cooler 250.
[0053] The component air conditioning 200 may further include: a battery coolant heater 260, a first radiator 275, a second radiator 270, a first pump 280, a second pump 290, and a third pump 420. The battery coolant heater 260 heats the coolant circulating in the first battery line 240; the first radiator 275 cools the coolant circulating in the electrical component line 220; the second radiator 270 cools the coolant circulating in the first battery line 240; the first pump 280 circulates the coolant in the electrical component line 220; the second pump 290 circulates the coolant in the first battery line 240; and the third pump 420 circulates the coolant in the second battery line 410. Here, the first radiator 275 and the second radiator 270 may be located at the lower or front of the vehicle to be cooled by airflow generated during driving.
[0054] Controller 300 can be based on Figure 49 The various control conditions shown effectively perform thermal management of the passenger space, electrical components 210, and high-voltage battery 230 by controlling the operation of the compressor 110, electric heater, and first damper driver 194 of the in-vehicle air conditioning 100, as well as the operation of the first pump 280, second pump 290, and battery cooling water heater 260 of the component air conditioning 200.
[0055] refer to Figures 2 to 12 as well as Figure 49 The operation of the thermal management system under various modes according to a first exemplary embodiment of the present invention, as well as the flow of refrigerant and coolant, will now be described.
[0056] When operating at high temperatures (e.g., in summer, causing the temperature of the passenger compartment and electrical components 210 to be higher than a reference temperature), it is necessary to cool the passenger compartment and electrical components 210, such as... Figure 2 As shown, under the control of the controller 300, the compressor 110 can be started and the first flow path 160 and the second flow path 170 can be opened through the first damper driver 194 to supply cooling air from the fan 150 through the evaporator 130 to cool the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component line 220 and cool the coolant in the electrical component line 220 through the first radiator 275 to cool the electrical component 210.
[0057] Furthermore, when operating at high temperatures (such as in summer, where the temperature of the passenger compartment, electrical components 210, and high-voltage battery 230 exceeds a reference temperature) requiring cooling of the passenger compartment, electrical components 210, and high-voltage battery 230, this can be achieved by starting the compressor and simultaneously opening both the first flow path 160 and the second flow path 170 via the first damper actuator 194, supplying cooling air from the fan 150 through the evaporator 130 to the passenger compartment, thereby cooling the passenger compartment. Alternatively, the first pump 280 can be activated to circulate coolant in the electrical component pipeline 220, cooling the coolant in the electrical component pipeline 220 via the first radiator 275, thereby cooling the electrical components 210. Figure 3 As shown, under the control of the controller 300, the coolant in the first battery line 240 can be further cooled by starting the second pump 290 to circulate the coolant in the first battery line 240, thereby cooling the high-voltage battery 230.
[0058] Furthermore, when cooling of the high-voltage battery 230 and the passenger space is required during charging, cooling air from the fan 150 through the evaporator 130 can be supplied to the passenger space by starting the compressor 110 and simultaneously opening both the first flow path 160 and the second flow path 170 via the first damper driver 194, thereby cooling the passenger space. Additionally, as... Figure 4 As shown, under the control of the controller 300, the high-voltage battery 230 can be cooled by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230). Here, when the high-voltage battery 230 is charging, the controller 300 can perform control to communicate with the control unit (not shown) of the thermal management system provided in the charging station 400, thereby activating the thermal management system and causing the coolant to circulate in the second battery line 410.
[0059] The charging station 400, used to charge the high-voltage battery 230, can be equipped with, for example... Figure 50The thermal management system shown is used in this system. During charging of the vehicle's high-voltage battery 230, the coolant in the second battery line 410 is cooled by the thermal management system provided in the charging station 400, and the coolant circulates through the second battery line 410, thereby cooling the high-voltage battery 230. Here, the thermal management system provided in the charging station 400 can be a heat exchanger known in the art.
[0060] When the high-voltage battery 230 needs to be cooled or heated during charging, such as Figure 5 and Figure 9 As shown, the high-voltage battery 230 can be cooled or heated by circulating coolant in the second battery line 410 (which is located in the charging station 400 for charging the high-voltage battery 230).
[0061] Furthermore, when operating at low temperatures (such as in winter, when the temperature of the passenger compartment is below the reference temperature, while the temperature of the electrical components 210 is above the reference temperature), it is necessary to heat the passenger compartment and cool the electrical components 210. Figure 6 As shown, under the control of the controller 300, heated air from the fan 150 passing through the electric heater 190 can be supplied to the passenger space by starting the electric heater 190 and closing the first flow path 160 with the first damper driver 194 without starting the compressor 110. Furthermore, the coolant in the electrical component pipeline 220 can be circulated in the first pump 280 by starting the first pump 280 and cooled via the first radiator 275.
[0062] Furthermore, when operating at low temperatures (e.g., in winter, when the temperature of the passenger compartment and high-voltage battery 230 is below a reference temperature, while the temperature of the electrical components 210 is above a reference temperature), requiring heating of the passenger compartment, cooling of the electrical components 210, and heating of the high-voltage battery 230, the passenger compartment can be heated by activating the electric heater 190 and then closing the first flow path 160 via the first damper actuator 194, supplying heated air from the fan 150 through the electric heater 190 to the passenger compartment. Alternatively, the electrical components 210 can be cooled by activating the first pump 280 and circulating coolant in the electrical component lines 220 via the first radiator 275. Furthermore, as... Figure 7 As shown, under the control of the controller 300, the coolant can be further circulated in the first battery line 240 by activating the battery cooling water heater 260 and the second pump 290, thereby heating the high-voltage battery 230.
[0063] Furthermore, when heating of the passenger space and the high-voltage battery 230 is required during charging of the high-voltage battery 230, such as Figure 8As shown, under the control of the controller 300, the heated air from the fan 150 passing through the electric heater 190 can be supplied to the passenger space by starting the electric heater 190 and then closing the first flow path 160 through the first damper driver 194, thereby heating the passenger space. Furthermore, the high-voltage battery 230 can be heated by circulating the coolant in the second battery line 410 (which is located in the charging station 400 for charging the high-voltage battery 230).
[0064] In addition, when it is necessary to dehumidify the passenger space and cool the electrical components 210, such as Figure 10 As shown, under the control of the controller 300, the compressor 110 and the electric heater 190 can be started, and then both the first flow path 160 and the second flow path 170 can be opened simultaneously to supply air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, to the passenger space, thereby dehumidifying the passenger space. Furthermore, the first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled via the first radiator 275, thereby cooling the electrical component 210.
[0065] In addition, when it is necessary to heat and dehumidify the passenger space and cool the electrical components 210, such as Figure 11 As shown, under the control of the controller 300, the compressor 110 and the electric heater 190 can be started, and then the first flow path 160 can be closed by the first damper driver 194. The heated air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, can be supplied to the passenger space, thereby heating and dehumidifying the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled by the first radiator 275, thereby cooling the electrical component 210.
[0066] In addition, when it is necessary to heat and dehumidify the passenger space, cool the electrical components 210, and heat the high-voltage battery 230, such as Figure 12 As shown, under the control of the controller 300, the passenger space can be heated and dehumidified by starting the compressor 110 and the electric heater 190, and then closing the first flow path 160 by the first damper driver 194. The heated air supplied from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, can also be supplied to the passenger space. The passenger space can also be heated and dehumidified by starting the first pump 280 to circulate the coolant in the electrical component pipeline 220 and cooling the coolant in the electrical component pipeline 220 via the first radiator 275. Furthermore, the high-voltage battery 230 can be heated by starting the battery cooling water heater 260 and then starting the second pump 290 to circulate the coolant in the first battery pipeline 240.

[0068] Compared to the in-vehicle air conditioner 100 of the vehicle thermal management system according to the first exemplary embodiment, the in-vehicle air conditioner 100 of the vehicle thermal management system according to the second exemplary embodiment of the present invention may further include: a second condenser 191 and a second valve 192, through which refrigerant flowing from the compressor 110 flows into the second condenser 191; the second valve 192 is arranged between the second condenser 191 and the first condenser 120. Since the remaining structure of the in-vehicle air conditioner 100 is substantially the same as that of the in-vehicle air conditioner 100 of the vehicle thermal management system according to the first exemplary embodiment, its specific description is omitted.
[0069] Furthermore, since the structure and features of the air conditioning 200 component of the thermal management system of the vehicle according to the second exemplary embodiment of the present invention are substantially the same as those of the air conditioning 200 component of the thermal management system of the vehicle according to the first exemplary embodiment, a detailed description thereof is omitted.
[0070] refer to Figures 14 to 24 as well as Figure 49 The operation of the thermal management system under various modes according to a second exemplary embodiment of the present invention, as well as the flow of refrigerant and coolant, will now be described.
[0071] When operating at high temperatures (such as in summer) requiring cooling of the passenger compartment and electrical components 210, such as Figure 14 As shown, under the control of the controller 300, the compressor 110 can be started, the second valve 192 can be opened, the refrigerant flowing out of the first condenser 120 can be expanded through the first valve 180, and the second flow path 170 can be closed through the first damper driver 194, so that the cooling air from the fan 150 through the first flow path 160 can be supplied to the passenger space, thereby cooling the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210.
[0072] The reason for closing the second flow path 170 by the first damper actuator 194 is to improve the cooling performance of the passenger space by preventing the heat generated during the cooling of the refrigerant in the second condenser 191 from being supplied to the passenger space through the second flow path 170.
[0073] Furthermore, when cooling of the passenger compartment, electrical components 210, and high-voltage battery 230 is required at high temperatures (such as in summer), such as... Figure 15 As shown, under the control of the controller 300, the compressor 110 can be started to open the second valve 192, allowing the refrigerant flowing from the first condenser 120 to expand through the first valve 180, and the second flow path 170 can be closed through the first damper driver 194, supplying cooling air from the fan 150 through the first flow path 160 to the passenger space, thereby cooling the passenger space. The first pump 280 can also be started to circulate the coolant in the electrical component pipeline 220, cooling the coolant in the electrical component pipeline 220 via the first radiator 275, thereby cooling the electrical component 210. Furthermore, the second pump 290 can be started to circulate the coolant in the first battery pipeline 240, cooling the coolant in the first battery pipeline 240 via the second radiator 270, thereby cooling the high-voltage battery 230.
[0074] Furthermore, when cooling of both the high-voltage battery 230 and the passenger space is required during charging of the high-voltage battery 230, this can be achieved by starting the compressor 110, opening the second valve 192, allowing the refrigerant flowing from the first condenser 120 to expand through the first valve 180, and closing the second flow path 170 through the first damper actuator 194, thereby supplying cooling air from the fan 150 through the first flow path 160 to the passenger space, thus cooling the passenger space. Additionally, as... Figure 16 As shown, under the control of the controller 300, the high-voltage battery 230 can be cooled by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230). Here, when the high-voltage battery 230 is charging, the controller 300 can perform control to communicate with the control unit (not shown) of the thermal management system provided in the charging station 400, thereby activating the thermal management system and causing the coolant to circulate in the second battery line 410.
[0075] Furthermore, when cooling or heating of the high-voltage battery 230 is required during charging, such as... Figure 17 and Figure 21 As shown, under the control of the controller 300, the high-voltage battery 230 can be cooled or heated by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230).
[0076] Furthermore, when operating in low temperatures (such as in winter) requiring heating of the passenger compartment and cooling of electrical components, such as... Figure 18As shown, under the control of the controller 300, the compressor 110 and the electric heater can be started, the first valve 180 can be opened, the refrigerant flowing out of the second condenser 191 can be expanded through the second valve 192, and the first flow path 160 can be closed through the first damper driver 194, so that the heated air from the fan 150 through the second condenser 191 and the electric heater 190 can be supplied to the passenger space, thereby cooling the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210.
[0077] Furthermore, when it is necessary to heat the passenger space, cool the electrical components 210, and heat the high-voltage battery 230 at low temperatures (such as in winter), such as Figure 19 As shown, under the control of the controller 300, the compressor 110 and the electric heater can be started, the first valve 180 can be opened, the refrigerant flowing out of the second condenser 191 can be expanded through the second valve 192, and the first flow path 160 can be closed through the first damper driver 194, so that the heated air from the fan 150 through the second condenser 191 and the electric heater 190 can be supplied to the passenger space, thereby heating the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210. The high-voltage battery 230 can be heated by starting the battery cooling water heater 260 and starting the second pump 290 to circulate the coolant in the first battery pipeline 240.
[0078] Furthermore, when heating of the passenger space and the high-voltage battery 230 is required during charging of the high-voltage battery 230, such as Figure 20 As shown, under the control of the controller 300, the passenger space can be heated by starting the compressor 110 and the electric heater, opening the first valve 180, expanding the coolant flowing out of the second condenser 191 through the second valve 192, and supplying heated air from the fan 150 through the second condenser 191 and the electric heater 190 by closing the first flow path 160 through the first damper driver 194. The high-voltage battery 230 can also be heated by circulating the coolant in the second battery line 410 (which is provided in the charging station 40 for charging the high-voltage battery 230).
[0079] In addition, when it is necessary to dehumidify the passenger space and cool the electrical components 210, such as Figure 22As shown, under the control of the controller 300, the compressor 110 and the electric heater can be started, the first valve 180 can be opened, and the refrigerant flowing out of the second condenser 191 can be expanded through the second valve 192. The first flow path 160 and the second flow path 170 can be opened simultaneously through the first damper driver 194, so that the air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, can be supplied to the passenger space, thereby dehumidifying the passenger space. Furthermore, the first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210.
[0080] In addition, when it is necessary to heat and dehumidify the passenger space and cool the electrical components 210, such as Figure 23 As shown, under the control of the controller 300, the compressor 110 and the electric heater can be started, the first valve 180 can be opened, the refrigerant flowing out of the second condenser 191 can be expanded through the second valve 192, and the first flow path 160 can be closed through the first damper driver 194, so that the heated air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, can be supplied to the passenger space, thereby heating and dehumidifying the passenger space, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210.
[0081] Furthermore, when it is necessary to heat and dehumidify the passenger space, cool the electrical components 210, and heat the high-voltage battery 230, the compressor 110 and electric heater can be started, the first valve 180 opened, the refrigerant flowing from the second condenser 191 expanded through the second valve 192, and the first flow path 160 closed through the first damper actuator 194 to supply heated air from the fan 150, which has decreased in humidity after passing through the evaporator 130 and the electric heater 190, to the passenger space, thereby heating and dehumidifying the passenger space. Additionally, the first pump 280 can be started to circulate coolant in the electrical component pipeline 220, cooling the coolant in the electrical component pipeline 220 via the first radiator 275, thereby cooling the electrical components 210. Figure 24 As shown, under the control of the controller 300, the high-voltage battery 230 can be further heated by activating the battery cooling water heater 260 and by activating the second pump 290 to circulate the coolant in the first battery line 240.
[0082] Figure 25 This is a schematic diagram showing a vehicle thermal management system according to a third exemplary embodiment of the present invention.
[0083] refer to Figure 25According to a third exemplary embodiment of the present invention, the vehicle thermal management system may include an in-vehicle air conditioner 100 and a component air conditioner 200.
[0084] Unlike the in-vehicle air conditioning unit 100 of the vehicle thermal management system according to the first exemplary embodiment, the in-vehicle air conditioning unit 100 of the vehicle thermal management system according to the third exemplary embodiment of the present invention may further include: a third flow path 195, a second damper 196, and a second damper actuator 197. The third flow path 195 branches off from the second flow path 170 so as to be located below the second flow path 170, and the outlet portion of the third flow path 195 converges with the outlet portions of the first flow path 160 and the second flow path 170; the second damper 196 is configured to connect the second flow path 170 to the third flow path 195 or to separate the second flow path 170 from the third flow path 195; the second damper actuator 197 is configured to drive the second damper 196. In the vehicle thermal management system according to the third exemplary embodiment of the present invention, the end of the cooler 250 may be located in the third flow path 195, such as... Figure 25 As shown.
[0085] As described above, since the first body 10 and the second body 20 are combined and the second flow path 170 and the third flow path 195 are connected or separated from each other via the second damper actuator 197, the in-vehicle air conditioning 100 of the vehicle thermal management system according to the third exemplary embodiment of the present invention is configured such that the end of the cooler 250 is located in the third flow path 195, thereby selectively performing heat exchange between the air from the fan 150 through the evaporator 130 and the end of the cooler 250 according to the driving conditions, thereby enabling more efficient vehicle thermal management.
[0086] Since the remaining construction and features of the in-vehicle air conditioner 100 are substantially the same as those of the in-vehicle air conditioner 100 of the thermal management system of the vehicle according to the first exemplary embodiment described above, their specific description is omitted.
[0087] Furthermore, since the structure and features of the air conditioning 200 component of the vehicle thermal management system according to the third exemplary embodiment of the present invention are substantially the same as those of the air conditioning 200 component of the vehicle thermal management system according to the first embodiment of the present invention, its specific description is omitted.
[0088] refer to Figures 26 to 36 as well as Figure 49 The operation of the thermal management system of a vehicle according to a third exemplary embodiment of the present invention, as well as the flow of refrigerant and coolant, will now be described.
[0089] When driving at high temperatures (e.g., in summer) and requiring cooling of both the passenger compartment and electrical components, such as Figure 26 As shown, under the control of the controller 300, the compressor 110 can be started, and both the first flow path 160 and the second flow path 170 can be opened simultaneously by the first damper driver 194. The second flow path 170 and the third flow path 195 can be separated by the second damper driver 197. Cooling air from the fan 150 through the evaporator 130 can be supplied to the passenger space to cool the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220 and cool the coolant in the electrical component pipeline 220 through the first radiator 275 to cool the electrical component 210.
[0090] Furthermore, when operating at high temperatures (such as in summer) requiring cooling of the passenger compartment, electrical components 210, and high-voltage battery 230, such as... Figure 27 As shown, under the control of the controller 300, the compressor 110 can be started to close the second flow path 170 via the first damper driver 194, and the second flow path 170 can be connected to the third flow path 195 via the second damper driver 197, so as to supply cooling air from the fan 150 through the evaporator 130 to the passenger space, thereby cooling the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled via the first radiator 275, thereby cooling the electrical component 210. Furthermore, the second pump 290 can be started to circulate the coolant in the first battery pipeline 240, and the coolant in the first battery pipeline 240 can be cooled via the second radiator 270, thereby cooling the high-voltage battery 230.
[0091] Furthermore, when cooling of both the high-voltage battery 230 and the passenger space is required during charging of the high-voltage battery 230, this can be achieved by activating the compressor 110, closing the second flow path 170 via the first damper actuator 194, and separating the second flow path 170 from the third flow path 195 via the second damper actuator 197, thereby supplying cooling air from the fan 150 through the evaporator 130 to the passenger space, thus cooling the passenger space. Figure 28 As shown, under the control of the controller 300, the high-voltage battery 230 can also be cooled by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230). Here, when the high-voltage battery 230 is charging, the controller 300 can perform control to communicate with the control unit (not shown) of the thermal management system provided in the charging station 400, thereby activating the thermal management system and causing the coolant to circulate in the second battery line 410.
[0092] Furthermore, when cooling or heating of the high-voltage battery 230 is required during charging, such as... Figure 29 and Figure 33 As shown, under the control of the controller 300, the high-voltage battery 230 can be cooled or heated by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230).
[0093] Furthermore, when operating in low temperatures (such as in winter) requiring heating of the passenger compartment and cooling of electrical components, such as... Figure 30 As shown, under the control of the controller 300, the first flow path 160 can be closed by starting the electric heater, and the second flow path 170 can be separated from the third flow path 195 by the second damper driver 197, so that heated air from the fan 150 and the electric heater 190 can be supplied to the passenger space, thereby heating the passenger space. The coolant in the electrical component pipeline 220 can be circulated by starting the first pump 280, and the coolant in the electrical component pipeline 220 can be cooled by the first radiator 275, thereby cooling the electrical component 210.
[0094] Furthermore, when operating at low temperatures (such as in winter) requiring heating of the passenger compartment, cooling of electrical components 210, and heating of the high-voltage battery 230, the passenger compartment can be heated by activating the electric heater, closing the first flow path 160 via the first damper actuator 194, and separating the second flow path 170 from the third flow path 195 via the second actuator, supplying heated air from the fan 150 through the electric heater 190 to the passenger compartment. The passenger compartment can also be heated by circulating coolant in the electrical component lines 220 via the first pump 280, cooling the coolant in the electrical component lines 220 via the first radiator 275. Additionally, as... Figure 31 As shown, under the control of the controller 300, the high-voltage battery 230 can be heated by starting the battery cooling water heater 260 and by starting the second pump 290 to circulate the coolant in the first battery line 240.
[0095] Furthermore, when both the passenger space and the high-voltage battery 230 need to be heated during charging of the high-voltage battery 230, such as Figure 32As shown, under the control of the controller 300, the passenger space can be heated by activating the electric heater, closing the first flow path 160 via the first damper driver 194, and separating the second flow path 170 from the third flow path 195 via the second damper driver 197, supplying heated air from the fan 150 through the electric heater 190, and the high-voltage battery 230 can also be heated by circulating coolant in the second battery line 410 (which is provided in the charging station 400 for charging the high-voltage battery 230).
[0096] In addition, when it is necessary to dehumidify the passenger space and cool the electrical components 210, such as Figure 34 As shown, under the control of the controller 300, by starting the compressor 110 and the electric heater, both the first flow path 160 and the second flow path 170 can be opened simultaneously by the first damper driver 194, and the second flow path 170 can be separated from the third flow path 195 by the second damper driver 197, so that the air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, can be supplied to the passenger space, thereby dehumidifying the passenger space. In addition, by starting the first pump 280, the coolant can be circulated in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled by the first radiator, thereby cooling the electrical component 210.
[0097] In addition, when it is necessary to heat and dehumidify the passenger space and cool the electrical components 210, such as Figure 35 As shown, under the control of the controller 300, the first flow path 160 can be closed by starting the compressor 110 and the electric heater, and the second flow path 170 can be separated from the third flow path 195 by the second damper driver 197.

In addition, the first pump 280 can be started to circulate the coolant in the electrical component pipeline 220 and cool the coolant in the electrical component pipeline 220 via the first radiator 275, thereby cooling the electrical component 210.
[0098] In addition, when it is necessary to heat and dehumidify the passenger space, cool the electrical components 210, and heat the high-voltage battery 230, such as Figure 36As shown, under the control of the controller 300, the first flow path 160 can be closed by starting the compressor 110 and the electric heater, and the second flow path 170 can be separated from the third flow path 195 by the second damper driver 197, thereby supplying heated air from the fan 150, which has been dehumidified by passing through the evaporator 130 and the electric heater 190, to the passenger space, thereby heating and dehumidifying the passenger space.

Furthermore, the second pump 290 can be started to circulate the coolant in the first battery pipeline 240 to heat the high-voltage battery 230.
[0099] Figure 37 This is a schematic diagram illustrating a vehicle thermal management system according to a fourth exemplary embodiment of the present invention. (Reference) Figure 37 According to the fourth embodiment of the present invention, the vehicle thermal management system may include an in-vehicle air conditioner 100 and a component air conditioner 200.
[0100] Unlike the in-vehicle air conditioning 100 of the vehicle thermal management system according to the third exemplary embodiment, the vehicle thermal management system according to the fourth exemplary embodiment of the present invention may further include: a second condenser 191 and a second valve 192, wherein refrigerant flowing from the compressor 110 flows into the second condenser 191; the second valve 192 is arranged between the second condenser 191 and the first condenser 120.
[0101] Since the remaining construction and features of the in-vehicle air conditioner 100 are substantially the same as those of the in-vehicle air conditioner 100 of the thermal management system of the vehicle according to the third exemplary embodiment described above, their specific description is omitted.
[0102] Furthermore, since the structure and features of the air conditioning 200 component of the vehicle thermal management system according to the fourth exemplary embodiment of the present invention are substantially the same as those of the air conditioning 200 component of the vehicle thermal management system according to the first exemplary embodiment of the present invention, its specific description is omitted.
[0103] refer to Figures 38 to 48 as well as Figure 49 The operation of the thermal management system of a vehicle according to a fourth exemplary embodiment of the present invention, as well as the flow of refrigerant and coolant, will now be described.
[0104] When driving at high temperatures (such as in summer) and requiring cooling of both the passenger compartment and electrical components 210, such as Figure 38As shown, under the control of the controller 300, the compressor 110 can be started, the second valve 192 can be opened, the refrigerant flowing from the first condenser 120 can be expanded through the first valve 180, the second flow path 170 can be closed through the first damper actuator 194, and the second flow path 170 can be separated from the third flow path 195 through the second damper actuator 197. Cooling air from the fan 150 through the first flow path 160 is supplied to the passenger space, thereby cooling the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210.
[0105] Here, the reason for closing the second flow path 170 by the first damper actuator 194 and separating the second flow path 170 from the third flow path 195 by the second damper actuator 197 is to prevent the heat generated during the cooling of the refrigerant in the condenser from being supplied to the passenger space through the second flow path 170, and to prevent the cooling air from the fan 150 from being discharged through the third flow path 195, thereby improving the cooling performance of the passenger space.
[0106] Furthermore, when operating at high temperatures (such as in summer) requiring cooling of the passenger compartment, electrical components 210, and high-voltage battery 230, such as... Figure 39 As shown, under the control of the controller 300, the compressor 110 can be started, the second valve 192 can be opened, the refrigerant flowing from the first condenser 120 can be expanded through the first valve 180, the second flow path 170 can be closed through the first damper actuator 194, and the second flow path 170 can be connected to the third flow path 195 through the second damper actuator 197, thereby supplying cooling air from the fan 150 through the first flow path 160 to the passenger space, thereby cooling the passenger space. The first pump 280 can be started to circulate the coolant in the electrical component pipeline 220, and the coolant in the electrical component pipeline 220 can be cooled through the first radiator 275, thereby cooling the electrical component 210. Furthermore, the second pump 290 can be started to circulate the coolant in the first battery pipeline 240, and the coolant in the first battery pipeline 240 can be cooled through the second radiator 270, thereby cooling the high-voltage battery 230.
[0107] The ability of the second radiator 270 to cool the coolant in the first battery line 240 at high temperatures (such as in summer) may be limited. To address this problem, the present invention enables the cooling of the coolant in the first battery line 240 by connecting the second flow path 170 to the third flow path 195 via the second damper actuator 197, so that cooling air from the fan 150 can exchange heat with the cooler 250 located in the third flow path 195.
[0108] Furthermore, when it is necessary to cool the high-voltage battery 230 and the passenger space during charging, such as... Figure 40 As shown, under the control of the controller 300, the compressor 110 can be started, the second valve 192 opened, the refrigerant flowing from the first condenser 120 expanded through the first valve 180, the second flow path 170 closed through the first damper actuator 194, and the second flow path 170 separated from the third flow path 195 through the second damper actuator 197.
