Description

Technical Field

[0001] The present invention relates to a thermal management system for a vehicle, which effectively manages energy required for interior air conditioning, cooling of electric components, or cooling / heating of a battery in the field of thermal management of the vehicle. Background Art

[0002] In recent years, the implementation of environmental protection technology and the solution of problems such as energy depletion are becoming social issues related to electric vehicles. Electric vehicles are driven by a motor that outputs power through a battery. Therefore, electric vehicles have the advantages of not emitting carbon dioxide, generating less noise, and the energy efficiency of the motor is higher than that of the engine, so electric vehicles are attracting attention as environmentally friendly vehicles.

[0003] The core technology for realizing such electric vehicles is the technology related to the battery module, and in recent years, research has been actively conducted on reducing the weight and volume of the battery and shortening the charging time. When the battery module is used in an optimal temperature environment, it can maintain the best performance and a long service life. However, due to the heat generated in operation and the change of the external temperature, it is substantially difficult to use the battery module in the optimal temperature environment.

[0004] In addition, electric vehicles do not have a waste heat source generated by combustion in a specific engine such as an internal combustion engine, so the interior of the electric vehicle is heated by an electric heating device in winter. In addition, in order to improve the charging and discharging performance of the battery in severe cold periods, preheating is required, so a separate heating electric heater is used. That is, the following technology is adopted: the heating / cooling system for controlling the temperature of the battery module is operated separately from the heating / cooling system for the internal air conditioning of the vehicle to maintain the optimal temperature environment of the battery module. In other words, two independent heating / cooling systems are constructed, one for internal heating / cooling and the other for controlling the temperature of the battery module.

[0005] However, the existing operation method cannot effectively manage energy, resulting in a short vehicle driving distance, so long-distance driving cannot be achieved. In addition, the driving distance is reduced by more than 30% when cooling in summer, and by more than 40% when heating in winter, so the problem of winter heating, which does not exist in internal combustion engines, becomes serious. When a large-capacity positive temperature coefficient thermistor (PTC) is installed to solve the problem of winter heating, there are problems such as reduced driving distance and excessive manufacturing cost and weight due to the use of a heat pump.

[0030] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and are described below. Although the present invention will be described in conjunction with exemplary embodiments of the present invention, it should be understood that this specification is not intended to limit the present invention to those exemplary embodiments. On the contrary, the present invention is intended to cover not only exemplary embodiments of the present invention, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0031] Figure 1 is a schematic diagram showing a thermal management system of a vehicle according to an exemplary embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Fig. 9 is a schematic diagram showing the circulation of cooling water and refrigerant in a thermal management system of a vehicle according to an exemplary embodiment of the present invention, Fig.10 and Fig.11 is a schematic diagram illustrating a thermal management system of a vehicle according to various exemplary embodiments of the present invention.

[0032] A controller 150 is provided in an exemplary embodiment of the present invention. The controller 150 according to an exemplary embodiment of the present invention may be implemented by a non-volatile memory and a processor, the non-volatile memory being configured to store an algorithm for controlling the operation of various components of the vehicle or data on software commands for executing the algorithm, and the processor being configured to use the data stored in the memory to perform the operations described below. The memory and the processor may be separate chips. Alternatively, the memory and the processor may be integrated in a single chip. The processor may be implemented as one or more processors.

[0033] The controller 150 controls the operation of the first pump P1, the second pump P2, and the third pump P3, thereby controlling the flow of cooling water in the cooling water pipelines where the pumps are installed respectively. In addition, the controller 150 controls the operation of the compressor 43 in the refrigerant pipeline 40, thereby controlling the flow of the refrigerant in the refrigerant pipeline 40. The first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the fifth valve V5, and the sixth valve V6 are controlled by the controller 150 to selectively connect the cooling water pipelines to which the valves are connected respectively, or to control the flow rate. These valves are multi-way valves. The controller 150 controls whether to introduce air into the internal air conditioning heating core H by controlling the door 200. Therefore, when it is necessary to introduce air into the internal air conditioning heating core H, the controller 150 can open the internal air conditioning heating core by controlling the door 200. Therefore, when it is not necessary to introduce air into the internal air conditioning heating core H, the controller 150 can close the internal air conditioning heating core by controlling the door 200.

[0034] like Figure 1 As shown, a thermal management system of a vehicle according to an exemplary embodiment of the present invention includes: a battery line 10, an introduction line 20, a discharge line 30, a refrigerant line 40, and a water-cooled condenser 50, wherein the battery line 10 is connected to a high-voltage battery core B and has a first radiator R1, and cooling water flows through the battery line 10 by a first pump P1; the introduction line 20 has one end connected to the upstream side of the first radiator R1 in the battery line 10 and has the other end connected to the interior air-conditioning heating core H, and cooling water flows through the introduction line 20 by a second pump P2; the discharge line 30 has a One end portion on the upstream side of the high-voltage battery core B in the battery pipeline 10 has the other end portion connected to the internal air-conditioning heating core H, and the cooling water introduced through the inlet pipeline 20 flows through the discharge pipeline 30; the refrigerant pipeline 40 has an expansion valve 41, an internal air-conditioning cooling core 42, a compressor 43, a liquid reservoir A and an air-cooled condenser 44, and the refrigerant flows through the refrigerant pipeline 40; the water-cooled condenser 50 connects the refrigerant pipeline 40 and the inlet pipeline 20, and is installed so that the refrigerant on the downstream side of the compressor 43 in the refrigerant pipeline 40 exchanges heat with the cooling water in the inlet pipeline 20.

[0035] In an exemplary embodiment of the present invention, a battery line 10 is provided. The battery line 10 is connected to a high-voltage battery core B. A first radiator R1 is installed in the battery line 10, and cooling water may flow through the battery line 10 through a first pump P1. More specifically, a high-voltage battery core B is installed in the battery line 10 and a first radiator R1 for cooling the high-voltage battery core B using external air is installed. In addition, a first pump P1 controlled by a controller 150 to run and stop and circulate cooling water is installed in the battery line 10. The high-voltage battery core B may be a concept that includes both a heat dissipation unit directly connected to the high-voltage battery or a heat dissipation unit indirectly connected to the high-voltage battery through a separate cooling water line. The cooling water that has undergone heat exchange with the external air through the first radiator R1 is introduced into the high-voltage battery core B, so that the high-voltage battery core B can be cooled.

[0036] In the exemplary embodiment of the present invention, an introduction line 20 and a discharge line 30 are provided. The introduction line 20 has one end connected to the upstream side of the first radiator R1 in the battery line 10 and the other end connected to the interior air conditioning heating core H. A second pump P2 controlled by the controller 150 to operate and stop and circulate cooling water is installed in the introduction line 20. The discharge line 30 has one end connected to the upstream side of the high-voltage battery core B in the battery line 10 and the other end connected to the interior air conditioning heating core H. Therefore, since the discharge line 30 is connected to the interior air conditioning heating core H, the cooling water introduced through the introduction line 20 can be introduced. Therefore, the cooling water introduced from the battery line 10 to the introduction line 20 can be discharged back to the battery line 10 through the discharge line 30. On the other hand, as shown in the figure, a water heater W is provided in the exemplary embodiment of the present invention. Therefore, when the cooling water heated by the water heater W flows through the interior air conditioning heating core H, the temperature of the air flowing through the interior air conditioning heating core H increases, so the air with the increased temperature can be discharged to the interior of the vehicle.

[0037] A refrigerant line 40 is provided in an exemplary embodiment of the present invention. An expansion valve 41, an interior air conditioning cooling core 42, a compressor 43, and an air-cooled condenser 44 are installed in the refrigerant line 40. The air-cooled condenser 44, which removes heat of the refrigerant in the refrigerant line 40 using the outside air outside the vehicle, is installed in the refrigerant line 40. The refrigerant circulates through the compressor 43, which is operated in the refrigerant line 40 of the vehicle by the controller 150. The refrigerant heat-exchanges with the air flowing through the interior air conditioning cooling core 42, thereby cooling the air flowing through the interior air conditioning cooling core 42. Therefore, the cooled air can be discharged to the interior of the vehicle.

[0038] In addition, a water-cooled condenser 50 is provided in the exemplary embodiment of the present invention. The water-cooled condenser 50 is installed so that the refrigerant on the downstream side of the compressor 43 in the refrigerant line 40 exchanges heat with the cooling water in the introduction line 20. Therefore, the refrigerant line 40 and the introduction line 20 are thermally connected through the water-cooled condenser 50. That is, the refrigerant whose temperature is increased by the compressor 43 in the refrigerant line 40 and the cooling water in the introduction line 20 can exchange heat through the water-cooled condenser 50. Therefore, the refrigerant in the refrigerant line 40 can increase the temperature of the cooling water in the introduction line 20.

[0039] On the other hand, Figure 1 As shown, in an exemplary embodiment of the present invention, an electrical component pipeline 60 is provided. The electrical component pipeline 60 is connected to the electrical component core M and has a second radiator R2, and cooling water can flow through the electrical component pipeline 60 through a third pump P3. Specifically, the electrical component core M can be a concept that includes both a heat dissipation unit directly connected to the electrical device and a heat dissipation unit indirectly connected to the electrical device through a separate cooling water pipeline. Cooling water can flow through the electrical component pipeline 60 through the third pump P3 controlled to run and stop by the controller 150. The second radiator R2 is installed in the electrical component pipeline 60, and cooling water can flow through the electrical component pipeline 60 through the third pump P3 controlled to run and stop. Since the second radiator R2 is installed in the electrical component pipeline 60, cooling water can exchange heat with the outside air outside the vehicle through the second radiator R2. Therefore, the second radiator R2 is connected to the electrical component core M through the electrical component pipeline 60 for heat exchange.

[0040] like Figure 1 As shown, the thermal management system of the vehicle according to an exemplary embodiment of the present invention may further include: a first cooling water bypass line 70, a second cooling water bypass line 80 and a battery chiller 90, the first cooling water bypass line 70 having one end connected to the upstream side of the electrical component core M in the electrical component line 60 through a first valve V1 and the other end connected to the downstream side of the electrical component core M in the electrical component line 60; the second cooling water bypass line 80 having one end connected to the upstream side of the high-voltage battery core B in the battery line 10 through a second valve V2 and the other end connected to the downstream side of the high-voltage battery core B in the battery line 10; the battery chiller 90 is installed to allow the cooling water in the first cooling water bypass line 70 and the cooling water in the second cooling water bypass line 80 to undergo heat exchange.

[0041] Specifically, the first cooling water bypass line 70 has one end connected to the upstream side of the electric component core M in the electric component line 60 through the first valve V1 and the other end connected to the downstream side of the electric component core M in the electric component line 60. Specifically, the second cooling water bypass line 80 has one end connected to the upstream side of the high-voltage battery core B in the battery line 10 through the second valve V2 and the other end connected to the downstream side of the high-voltage battery core B in the battery line 10. As shown in the figure, the first cooling water bypass line 70 and the second cooling water bypass line 80 are connected through the battery chiller 90, so that the cooling water in the first cooling water bypass line 70 and the cooling water in the second cooling water bypass line 80 are heat exchanged. That is, since the first cooling water bypass line 70 and the second cooling water bypass line 80 are connected through the battery chiller 90, the cooling water flowing through the first cooling water bypass line 70 and the cooling water flowing through the second cooling water bypass line 80 are thermally connected.

[0042] At the same time, if Figure 1 As shown, the thermal management system of the vehicle according to the exemplary embodiment of the present invention further includes a first refrigerant bypass line 100 having one end connected to the upstream side of the expansion valve 41 in the refrigerant line 40 and the other end connected to the downstream side of the internal air conditioning cooling core 42 in the refrigerant line 40. The first refrigerant bypass line 100 is connected to the battery chiller 90 so that the refrigerant in the first refrigerant bypass line 100 can perform heat exchange with the cooling water in the first cooling water bypass line 70 or the cooling water in the second cooling water bypass line 80.

[0043] In an exemplary embodiment of the present invention, an expansion valve 51 is installed between the air-cooled condenser 44 and the water-cooled condenser 50 on the refrigerant line 40 .

[0044] In an exemplary embodiment of the present invention, the expansion valve 61 is installed between the air-cooled condenser 44 and the battery chiller 90 on the first refrigerant bypass line 100 .

[0045] Reference Figure 1 , the first refrigerant bypass line 100 has one end connected to the upstream side of the expansion valve 41 in the refrigerant line 40 and the other end connected to the downstream side of the internal air conditioning cooling core 42 in the refrigerant line 40. Since the first refrigerant bypass line 100 is connected to the battery chiller 90, the refrigerant in the first refrigerant bypass line 100 can perform heat exchange with the cooling water in the first cooling water bypass line 70 or the cooling water in the second cooling water bypass line 80. Therefore, the first refrigerant bypass line 100, the first cooling water bypass line 70, and the second cooling water bypass line 80 are thermally connected.

[0046] According to the thermal management system of the vehicle of the present invention, in a first mode, external air outside the vehicle is used to cool the high-voltage battery core B and the cooled air is discharged into the interior of the vehicle, and the controller 150 controls the compressor 43, the second valve V2, the first pump P1 and the second pump P2, so that the refrigerant can circulate through the refrigerant line 40 and the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the first radiator R1.

[0047] The controller 150 controls the compressor 43, the second valve V2, the first pump P1, and the second pump P2. Figure 2 , the controller 150 controls the compressor 43 so that the refrigerant circulates through the refrigerant line 40. In addition, the controller 150 controls the second valve V2, the first pump P1, and the second pump P2 so that the cooling water circulates through the battery line 10, the introduction line 20, and the discharge line 30. Therefore, the cooling water that has passed through the high-voltage battery core B is led back to the high-voltage battery core B after passing through the first radiator R1. Therefore, the air passing through the interior air conditioning cooling core 42 is cooled by heat exchange with the refrigerant in the refrigerant line 40, and then discharged to the interior of the vehicle. In addition, the cooling water that has been cooled by heat exchange with the outside air outside the vehicle through the first radiator R1 is introduced into the high-voltage battery core B, thereby cooling the high-voltage battery core B.

[0048] According to the thermal management system of the vehicle of the present invention, in the second mode, external air outside the vehicle is used to cool the high-voltage battery core B and the electrical component core M and the cooled air is discharged to the interior of the vehicle, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant can circulate through the refrigerant pipeline 40, the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the first radiator R1, and the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the second radiator R2.

[0049] The controller 150 controls the compressor 43, the first valve V1, the second valve V2, the first pump P1, the second pump P2, and the third pump P3. Figure 2, the controller 150 controls the compressor 43 so that the refrigerant circulates through the refrigerant line 40. In addition, the controller 150 controls the second valve V2, the first pump P1, and the second pump P2 so that the cooling water circulates through the battery line 10, the introduction line 20, and the discharge line 30. Therefore, the cooling water that has passed through the high-voltage battery core B is led back to the high-voltage battery core B after passing through the first radiator R1. Therefore, the air passing through the interior air conditioning cooling core 42 is cooled by heat exchange with the refrigerant in the refrigerant line 40, and then discharged to the interior of the vehicle. In addition, the cooling water that has been cooled by heat exchange with the outside air outside the vehicle through the first radiator R1 is introduced into the high-voltage battery core B, thereby cooling the high-voltage battery core B.

[0050] Furthermore, the controller 150 controls the third pump P3 to circulate cooling water through the electric component line 60. Therefore, the cooling water having been cooled by heat exchange with the outside air outside the vehicle via the second radiator R2 is introduced into the electric component core M, thereby cooling the electric component core M.

[0051] At the same time, if Figure 1 As shown, the thermal management system of the vehicle according to an exemplary embodiment of the present invention may further include a third cooling water bypass line 110 having one end connected to the downstream side of the high-voltage battery core B in the battery line 10 through a third valve V3 and the other end connected to the exhaust line 30.

[0052] The third cooling water bypass line 110 has one end connected to the downstream side of the high-voltage battery core B in the battery line 10 through the third valve V3 and the other end connected to the exhaust line 30. Therefore, the controller 150 controls the second valve V2 and the third valve V3 so that the cooling water in the exhaust line can be introduced into the high-voltage battery core B or can pass through the third cooling water bypass line 110 without being introduced into the high-voltage battery core B.

[0053] According to the thermal management system of the vehicle of the present invention, in the third mode, the battery chiller 90 is used to cool the high-voltage battery core B, the external air outside the vehicle is used to cool the electrical component core M and the cooled air is discharged to the interior of the vehicle, the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant can circulate through the refrigerant line 40 and the first refrigerant bypass line 100, the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80, the cooling water that has passed through the first radiator R1 can be introduced into the first radiator R1 after passing through the introduction line 20, the discharge line 30 and the third cooling water bypass line 110, and the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the second radiator R2.

[0054] Reference Figure 3 , the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the first pump P1, the second pump P2, and the third pump P3. The controller 150 controls the compressor 43 so that the refrigerant circulates through the refrigerant line 40 and the first refrigerant bypass line 100. In addition, the controller 150 controls the second valve V2 and the first pump P1 so that the cooling water that has passed through the high-voltage battery core B is introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80. Therefore, the cooling water in the second cooling water bypass line 80 is thermally connected to the first refrigerant bypass line 100 through the battery chiller 90. Therefore, the cooling water in the second cooling water bypass line 80 is cooled by the refrigerant in the first refrigerant bypass line 100. Therefore, as the cooling water in the second cooling water bypass line 80 is cooled, the high-voltage battery core B is cooled. In addition, the controller 150 controls the third valve V3 and the second pump P2 so that the cooling water that has passed through the first radiator R1 is introduced into the first radiator R1 after passing through the introduction line 20, the discharge line 30, and the third cooling water bypass line 110. Therefore, the cooling water in the introduction line 20 is thermally connected with the refrigerant in the refrigerant line 40 through the water-cooled condenser 50. Therefore, the cooling water in the introduction line 20 increases in temperature by heat exchange with the refrigerant in the refrigerant line 40, circulates, and then cools again through the first radiator R1. That is, the heat generated by the high-voltage battery core B is transferred to the first refrigerant bypass line 100 through the battery chiller 90. The heat transferred from the high-voltage battery core B is transferred to the first radiator R1 through the water-cooled condenser 50, and then dissipated through the first radiator R1. In addition, the controller 150 controls the first valve V1 and the third pump P3 so that the cooling water circulates through the electrical component line 60. Therefore, waste heat of the electric component core M is dissipated through the second radiator R2.

[0055] According to the thermal management system of the vehicle of the present invention, in the fourth mode, external air outside the vehicle is used to cool the electrical component core M and the cooled air is discharged to the interior of the vehicle, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the second pump P2 and the third pump P3, so that the refrigerant can circulate through the refrigerant pipeline 40, and the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the second radiator R2, and the cooling water that has passed through the first radiator R1 can be introduced into the first radiator R1 after passing through the introduction pipeline 20, the discharge pipeline 30 and the third cooling water bypass pipeline 110.

[0056] Reference Figure 4 , the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the second pump P2, and the third pump P3. The controller 150 controls the compressor 43 so that the refrigerant circulates through the refrigerant pipeline 40. In addition, the controller 150 controls the first valve V1 and the third pump P3 so that the cooling water circulates through the electrical component pipeline 60. Therefore, the waste heat of the electrical component core M is dissipated through the second radiator R2. In addition, the controller 150 controls the second valve V2, the third valve V3, and the second pump P2 so that the cooling water that has passed through the first radiator R1 can be introduced into the first radiator R1 after passing through the introduction pipeline 20, the discharge pipeline 30, and the third cooling water bypass pipeline 110. Therefore, the cooling water introduced into the pipeline 20 is increased in temperature by heat exchange with the refrigerant in the refrigerant pipeline 40 via the water-cooled condenser 50, and then dissipated through the first radiator R1. Furthermore, the refrigerant in the refrigerant line 40 cools the air flowing through the interior air-conditioning cooling core 42 while circulating, so that the cooled air can be discharged to the interior of the vehicle.

[0057] According to the thermal management system of the vehicle of the present invention, in the fifth mode, the battery chiller 90 is used to cool the high-voltage battery core B and the external air outside the vehicle is used to cool the electrical component core M, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant can circulate through a portion of the refrigerant pipeline 40 and the first refrigerant bypass line 100, the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80, and the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the second radiator R2.

[0058] Reference Figure 5, the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the first pump P1, the second pump P2, and the third pump P3. The controller 150 controls the compressor 43 so that the refrigerant circulates through a portion of the refrigerant line 40 and the first refrigerant bypass line 100. Therefore, the refrigerant that has passed through the compressor 43, the water-cooled condenser 50, and the air-cooled condenser 44 in the refrigerant line 40 passes through the battery chiller 90 via the first refrigerant bypass line 100 and is then introduced back to the compressor 43. In addition, the controller 150 controls the second valve V2 and the first pump P1 so that the cooling water that has passed through the high-voltage battery core B is introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80. Therefore, the cooling water in the second cooling water bypass line 80 is thermally connected to the refrigerant in the first refrigerant bypass line 100, and the refrigerant in the first refrigerant bypass line 100 cools the cooling water in the second cooling water bypass line 80. Therefore, the battery chiller 90 can be used to cool the high-voltage battery core B. In addition, the controller 150 controls the first valve V1 and the third pump P3 so that the cooling water that has passed through the electrical component core M is introduced into the electrical component core M after passing through the second radiator R2. Therefore, the waste heat of the electrical component pipeline 60 is dissipated through the second radiator R2. In addition, the controller 150 controls the third valve V3 and the second pump P2 so that the cooling water that has passed through the first radiator R1 is introduced into the first radiator R1 after passing through the introduction line 20, the discharge line 30, and the third cooling water bypass line 110. Therefore, the cooling water in the introduction line 20 and the refrigerant in the refrigerant line 40 are heat exchanged through the water-cooled condenser 50, so that the temperature of the cooling water in the introduction line 20 is increased and the refrigerant in the refrigerant line 40 is further cooled.

[0059] At the same time, if Figure 1 As shown, the thermal management system of the vehicle according to the exemplary embodiment of the present invention may further include a fourth cooling water bypass line 120, which has one end connected to the upstream side of the first radiator R1 in the battery line 10 through a fourth valve V4 and the other end connected to the downstream side of the radiator R1 in the battery line 10.

[0060] The fourth cooling water bypass line 120 has one end connected to the upstream side of the first radiator R1 in the battery line 10 through the fourth valve V4 and the other end connected to the downstream side of the first radiator R1 in the battery line 10. Therefore, when the fourth valve V4 is controlled by the controller 150, the cooling water in the battery line 10 flows through the fourth cooling water bypass line 120, so the cooling water can be prevented from flowing to the first radiator R1. In addition, the cooling water can be made to flow to the first radiator R1 instead of the fourth cooling water bypass line 120.

[0061] According to the thermal management system of the vehicle of the present invention, in the sixth mode, the battery chiller 90 is used to cool the electrical component core M and the high-voltage battery core B and discharge the air with the increased temperature to the interior of the vehicle, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant can circulate through a portion of the refrigerant pipeline 40 and the first refrigerant bypass line 100, the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the first cooling water bypass line 70, the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80, and the cooling water can circulate through the inlet pipeline 20, the discharge pipeline 30, the third cooling water bypass line 110 and the fourth cooling water bypass line 120.

[0062] Reference Figure 6, the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2, and the third pump P3. The controller 150 controls the compressor 43 so that the refrigerant circulates through a portion of the refrigerant line 40 and the first refrigerant bypass line 100. In addition, the controller 150 controls the first valve V1 and the third pump P3 so that the cooling water that has passed through the electric component core M is introduced into the electric component core M after passing through the first cooling water bypass line 70, thereby recovering the waste heat of the electric component core M. In addition, the controller 150 controls the second valve V2, the third valve V3, and the first pump P1 so that the cooling water that has passed through the high-voltage battery core B is introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80, thereby recovering the waste heat of the high-voltage battery core B. In addition, the refrigerant in the first refrigerant bypass line 100 cools the cooling water in the first cooling water bypass line 70 and the cooling water in the second cooling water bypass line 80 through the battery chiller 90. In addition, the controller 150 controls the third valve V3, the fourth valve V4, and the second pump P2 so that the cooling water can circulate through the introduction line 20, the discharge line 30, the third cooling water bypass line 110, and the fourth cooling water bypass line 120. Therefore, the cooling water in the introduction line 20 is increased in temperature by heat exchange with the refrigerant in the refrigerant line 40 via the water-cooled condenser 50. The cooling water with increased temperature is introduced into the interior air conditioning heating core H through the introduction line 20 and increases the temperature of the air flowing through the interior air conditioning heating core H. Therefore, the air with increased temperature can be discharged to the interior of the vehicle. In addition, the cooling water that has passed through the interior air conditioning heating core H circulates through the discharge line 30, the third cooling water bypass line 110, a portion of the battery line 10, and the fourth cooling water bypass line 120. In this case, when the water heater W installed in the introduction line 20 is used, the cooling water whose temperature is further increased may be introduced into the interior air-conditioning heating core H from the introduction line 20 .

[0063] According to the thermal management system of the vehicle of the present invention, in the seventh mode, a water-cooled condenser 50 is used to increase the temperature of the high-voltage battery core B and discharge the air with the increased temperature to the interior of the vehicle, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant can circulate through a portion of the refrigerant pipeline 40 and the first refrigerant bypass line 100, and the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the fourth cooling water bypass line 120, the inlet line 20 and the outlet line 30, and the cooling water that has passed through the electrical component core M can be introduced into the electrical component core M after passing through the first cooling water bypass line 70.

[0064] Reference Fig. 9 , the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2, and the third pump P3. The controller 150 controls the compressor 43 so that the refrigerant circulates through a portion of the refrigerant line 40 and the first refrigerant bypass line 100. In addition, the controller 150 controls the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, and the second pump P2 so that the cooling water that has passed through the high-voltage battery core B can be introduced into the high-voltage battery core B after passing through the fourth cooling water bypass line 120, the introduction line 20, and the discharge line 30. Therefore, the cooling water in the introduction line 20 is increased in temperature by heat exchange with the refrigerant in the refrigerant line 40 via the water-cooled condenser 50, and then flows through the interior air conditioning heating core H. Therefore, the temperature of the air flowing through the interior air conditioning heating core H is increased, and thus the air with increased temperature is discharged to the interior of the vehicle. In addition, the controller 150 controls the first valve V1 and the third pump P3 so that the cooling water having passed through the electric component core M is introduced into the electric component core M after passing through the first cooling water bypass line 70. Therefore, the temperature of the cooling water having passed through the electric component core M is increased, and then heat-exchanged with the refrigerant in the first refrigerant bypass line 100 through the battery chiller 90. Therefore, there is an advantage of utilizing the waste heat of the electric component core M. In addition, when the water heater W is used, the cooling water whose temperature is further increased can be introduced into the interior air-conditioning heating core H.

[0065] like Fig.10 As shown, the thermal management system of the vehicle according to various exemplary embodiments of the present invention may further include a fifth cooling water bypass line 130 having one end connected to the upstream side of the water-cooled condenser 50 in the battery line 10 through a fifth valve V5 and the other end connected to the downstream side of the water-cooled condenser 50. In this case, the controller 150 may control the fifth valve V5 so that the cooling water flows to the fifth cooling water bypass line 130, or so that the cooling water flows to the water-cooled condenser 50 without flowing to the fifth cooling water bypass line 130. When the cooling water flows to the fifth cooling water bypass line 130, the cooling water does not flow through the water-cooled condenser 50, and thus the cooling water may be prevented from being raised in temperature by the refrigerant in the refrigerant line 40.

[0066] like Fig.11 As shown, the thermal management system of the vehicle according to various exemplary embodiments of the present invention may further include a second refrigerant bypass line 140 having one end connected to the upstream side of the water-cooled condenser 50 in the refrigerant line 40 and the other end connected to the downstream side of the water-cooled condenser 50 through a sixth valve V6.

[0067] In this case, the controller 150 may control the sixth valve V6 so that the refrigerant flows to the second refrigerant bypass line 140, or so that the refrigerant flows to the water-cooled condenser 50 instead of the second refrigerant bypass line 140. When the refrigerant flows to the second refrigerant bypass line 140, the refrigerant does not flow through the water-cooled condenser 50, and thus the refrigerant may be prevented from being condensed by the cooling water introduced into the line 20.

[0068] like Figure 4 As shown, according to an exemplary embodiment of the present invention, according to the thermal management system of the vehicle, in the eighth mode, the cooled air is discharged to the interior of the vehicle, the controller 150 controls the compressor 43, the second valve V2, the third valve V3, the fourth valve V4 and the second pump P2, so that the refrigerant in the refrigerant line 40 circulates, and the cooling water circulates through a portion of the battery line 10, the introduction line 20, the discharge line 30 and the third cooling water bypass line 110. In this case, the refrigerant in the refrigerant line 40 exchanges heat with the air flowing through the interior air conditioning cooling core 42, so that the cooled air is discharged to the interior of the vehicle. In addition, the cooling water that has been cooled by the first radiator R1 exchanges heat with the refrigerant in the refrigerant line 40 through the water-cooled condenser 50, so that the refrigerant in the refrigerant line 40 flowing through the water-cooled condenser 50 can be cooled.

In this case, the refrigerant in the refrigerant line 40 exchanges heat with the cooling water in the introduction line 20 through the water-cooled condenser 50, so that the cooling water with a raised temperature is introduced into the interior air conditioning heating core H. Therefore, the temperature of the air passing through the interior air conditioning heating core H is raised, and thus the air with a raised temperature is discharged to the interior of the vehicle. In this case, as shown in the figure, the cooling water in the first cooling water bypass line 70 and the second cooling water bypass line 80 exchanges heat with the refrigerant in the refrigerant bypass line through the battery chiller 90, thereby having the advantage of also being able to cool the high-voltage battery core B and the electric component core M.

[0070] like Figure 7 As shown, according to an exemplary embodiment of the present invention, according to the thermal management system of the vehicle, in the tenth mode, the dehumidified air is discharged to the interior of the vehicle, and the controller 150 controls the compressor 43, the first valve V1, the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2 and the third pump P3, so that the refrigerant circulates through the refrigerant line 40 and the refrigerant bypass line, and the cooling water that has passed through the third cooling water bypass line 110 is introduced into the interior air-conditioning heating core H after passing through the introduction line 20, the cooling water that has passed through the interior air-conditioning heating core H passes through the fourth cooling water bypass line 120, the cooling water that has passed through the high-voltage battery core B is introduced into the high-voltage battery core B after passing through the second cooling water bypass line 80, and the cooling water that has passed through the electrical component core M is introduced into the electrical component core M after passing through the first cooling water bypass line 70.

[0071] The air flowing through the interior air conditioning cooling core 42 is dehumidified and cooled by heat exchange, and the refrigerant in the refrigerant line 40 exchanges heat with the cooling water in the introduction line 20 through the water-cooled condenser 50, so that the cooling water with increased temperature is introduced into the interior air conditioning heating core H and the temperature of the air flowing through the interior air conditioning heating core H increases, so that the dehumidified air is discharged to the interior of the vehicle. In this case, as shown in the figure, the cooling water in the first cooling water bypass line 70 and the second cooling water bypass line 80 exchanges heat with the refrigerant in the refrigerant bypass line through the battery chiller 90, thereby having the advantage of also being able to cool the high-voltage battery core B and the electric component core M.

[0072] like Figure 8 As shown, according to an exemplary embodiment of the present invention, according to the thermal management system of the vehicle, in the eleventh mode, the temperature of the high-voltage battery core B is increased using the water heater W, and the controller 150 controls the second valve V2, the third valve V3, the fourth valve V4, the first pump P1, the second pump P2, and the water heater W, so that the cooling water that has passed through the high-voltage battery core B circulates to be introduced back to the high-voltage battery core B after passing through the fourth cooling water bypass line 120. In this case, the cooling water whose temperature is increased by the water heater W is introduced into the high-voltage battery core B, and the temperature of the high-voltage battery core B can be increased.
