Description

[0001] Cross - reference to related applications

[0002] This application claims priority and the benefit of Korean Patent Application No. 10 - 2024 - 0005949, filed on January 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a heat pump system for a vehicle. More specifically, the present disclosure relates to a heat pump system for a vehicle capable of improving heating performance. Background Art

[0004] Generally, an air - conditioning system for a vehicle includes an air - conditioning unit that circulates a refrigerant to heat or cool the interior of the vehicle.

[0005] The air - conditioning unit, which can maintain the interior of the vehicle at an appropriate temperature regardless of external temperature changes, is configured to heat or cool the interior of the vehicle by performing heat exchange using a condenser and an evaporator as the refrigerant discharged by driving a compressor passes through the condenser, a liquid receiver dryer, an expansion valve, and the evaporator and then returns to the compressor.

[0006] That is, in the cooling mode, the air - conditioning unit condenses the high - temperature and high - pressure gaseous refrigerant compressed by the compressor through the condenser, allows the refrigerant to pass through the liquid receiver dryer and the expansion valve, and then evaporates the refrigerant in the evaporator to lower the temperature and humidity inside the vehicle.

[0007] In recent years, as concerns about energy efficiency and environmental pollution have been increasing, there has been a desire to develop environmentally friendly vehicles that can substantially replace internal combustion engine vehicles. Environmentally friendly vehicles are classified into electric vehicles driven by using a fuel cell or electricity as a power source and hybrid vehicles driven by using an engine and a battery.

[0008] In these environmentally friendly vehicles, unlike the air - conditioning of general vehicles, a separate heater is not used. The air - conditioning used in environmentally friendly vehicles is generally referred to as a heat pump system.

[0009] An electric vehicle driven by a power source of a fuel cell generates a driving force by converting the chemical reaction energy between oxygen and hydrogen into electrical energy. In this process, heat energy is generated through the chemical reaction in the fuel cell. Therefore, it is desired to ensure the performance of the fuel cell by effectively removing the generated heat.

[0010] In addition, a hybrid vehicle generates a driving force by driving an electric motor together with an engine operated by fossil fuel using the power supplied from the above - mentioned fuel cell or battery. Therefore, the heat generated by the fuel cell or battery and the electric motor should be effectively removed to ensure the performance of the electric motor.

[0011] Therefore, in a hybrid vehicle or an electric vehicle according to the prior art, a cooling device, a heat pump system, and a battery cooling system should be respectively configured as separate closed loops to prevent heat generation in an electric motor, electrical components, and a battery including a fuel cell.

[0012] Therefore, the size and weight of a cooling module provided at the front of the vehicle increase. In addition, the layout of connection pipes for supplying refrigerant and coolant from an engine compartment to each of the heat pump system, the cooling device, and the battery cooling system becomes complicated.

[0013] In addition, since a battery cooling system for heating or cooling a battery is separately provided according to the state of the vehicle to obtain the best performance of the battery, a plurality of valves for selectively interconnecting connection pipes are employed, and thus noise and vibration generated due to frequent opening and closing operations of the valves may be transmitted to the interior of the vehicle, thereby reducing riding comfort.

[0014] In addition, since a separate heat exchanger should be employed to recover waste heat from various heat sources in a heating mode of the vehicle, there is also a disadvantage of increasing manufacturing costs.

[0015] The above information disclosed in this background art section is only for enhancing the understanding of the background of the present disclosure, and thus it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0016] The present disclosure provides a heat pump system for a vehicle, which is configured to selectively exchange heat between thermal energy generated by a coolant and a refrigerant when the refrigerant condenses and evaporates. The heat pump system can use the heat-exchanged high-temperature coolant to heat the interior of the vehicle.

[0017] The present disclosure provides a heat pump system for a vehicle, which is configured to improve the heating efficiency of the vehicle by selectively using ambient air heat, waste heat of electrical components, and waste heat of a battery module when heating the interior of the vehicle, such that the heat pump system increases the overall driving distance of the vehicle by effectively regulating the temperature of the battery module to achieve the best performance of the battery module.

[0018] In one embodiment of the present disclosure, a heat pump system for a vehicle may include a valve module including a plurality of ports through which coolant may be introduced or discharged; a first pipeline having a first end and a second end connected to the valve module to allow the coolant to flow. The first pipeline further includes a radiator and electrical components. The heat pump system further includes a second pipeline having a first end and a second end connected to the valve module to allow the coolant to flow. The second pipeline further includes a battery module and a cooler. The heat pump system further includes a third pipeline having a first end and a second end connected to the valve module to allow the coolant to flow. The third pipeline further includes a condenser and a heating core. In particular, the valve module is configured to selectively connect at least two of the first pipeline, the second pipeline, and the third pipeline based on at least one mode of regulating the temperature inside the vehicle and the temperature of the battery module. The valve module is configured to control the flow of the coolant.

[0019] The at least one mode may include: a first mode in which the coolant cooled by the radiator is used to cool the electrical components and the battery module; and a second mode in which the coolant cooled by the radiator is used to cool the interior of the vehicle, the electrical components, and the battery module. The at least one mode may further include: a third mode in which the coolant cooled by the radiator is used to cool the interior of the vehicle and the electrical components, and the coolant cooled by the cooler is used to cool the battery module; and a fourth mode for heating the interior of the vehicle and the battery module while recovering the heat of the ambient air and the waste heat of the electrical components. The at least one mode may further include a fifth mode in which the interior of the vehicle is heated by recovering the heat of the ambient air, the waste heat of the electrical components, and the waste heat of the battery module. The at least one mode may further include a sixth mode in which the interior of the vehicle is heated by an electric heater and the waste heat of the coolant is recovered while heating the battery module.

[0020] In the first mode, the first pipeline may be connected to the second pipeline through the operation of the valve module so that the coolant cooled by the radiator can be introduced into the electrical components and the battery module, the third pipeline may be closed through the operation of the valve module, and the coolant cooled by the radiator can pass through the battery module and then be introduced into the electrical components.

[0021] In the second mode, the first pipeline, the second pipeline, and the third pipeline may be interconnected through the operation of the valve module so that the coolant cooled by the radiator is introduced into the electrical components, the battery module, and the condenser. In particular, the coolant cooled by the radiator may first pass through the battery module, then through the condenser, and finally be introduced into the electrical components.

[0022] In the third mode, the first pipeline can be connected to the third pipeline through the operation of the valve module, so that the coolant cooled by the radiator can be introduced into the electrical components and the condenser. The second pipeline can form an independent closed loop through which the coolant circulates through the operation of the valve module, so that the coolant cooled by the cooler can be supplied to the battery module, and the coolant cooled by the radiator can pass through the condenser and then be introduced into the electrical components.

[0023] In the fourth mode, the first pipeline can be connected to the third pipeline through the operation of the valve module, so that the coolant that has passed through the radiator and the electrical components can be introduced into the condenser. The third pipeline can be connected to the second pipeline through the operation of the valve module, so that the coolant that has passed through the condenser can be introduced into the battery module and the cooler. The coolant whose temperature has risen when passing through the condenser can be introduced into the heating core along the third pipeline, and the coolant that has passed through the heating core can be introduced into the battery module.

[0024] In the fifth mode, the first pipeline can be connected to the second pipeline through the operation of the valve module, so that the coolant that has passed through the radiator, the electrical components and the battery module can be introduced into the cooler. The third pipeline can form an independent closed loop through the operation of the valve module, so that the coolant can sequentially pass through the condenser and the heating core along the third pipeline. The coolant whose temperature has risen when passing through the condenser can be introduced into the heating core along the third pipeline, and the cooler can be configured to exchange heat between the coolant that has passed through the radiator, the electrical components, the battery module and the refrigerant, while recovering the heat of the ambient air, the waste heat of the electrical components and the waste heat of the battery module.

[0025] In the sixth mode, the first pipeline can be closed through the operation of the valve module. The third pipeline can be connected to the second pipeline through the operation of the valve module, so that the coolant that has passed through the condenser and the electric heater can sequentially pass through the battery module and the cooler. The electric heater can operate, and the coolant whose temperature has risen by the electric heater can be introduced into the heating core along the third pipeline. The battery module can use the coolant whose temperature has risen when passing through the electric heater to raise its temperature, and the cooler recovers the remaining waste heat in the coolant that has passed through the battery module.

[0026] The valve module can include a first port connecting the first end of the first pipeline, a second port connecting the second end of the first pipeline, a third port connecting the first end of the second pipeline, a fourth port connecting the second end of the second pipeline, a fifth port connecting the first end of the third pipeline, and a sixth port connecting the second end of the third pipeline.

[0027] The heat pump system can further include a first water pump disposed in the second pipeline and a second water pump disposed in the third pipeline.

[0028] The electric heater can be further arranged in the third pipeline so that the coolant can pass through the condenser and the electric heater in sequence.

[0029] The electric heater can be arranged separately from the condenser in the third pipeline or can be integrally formed with the condenser.

[0030] The autonomous driving controller can be arranged in the second pipeline.

[0031] As described above, for the heat pump system for a vehicle according to the embodiment, by selectively exchanging heat between the coolant and the thermal energy generated from the refrigerant during refrigerant condensation and evaporation, and by using the high-temperature coolant after heat exchange to heat the vehicle interior, the entire system can be simplified, and the layout of the connecting pipes through which the refrigerant circulates can be simplified.

[0032] In addition, according to the present disclosure, by selectively using the ambient air heat, the waste heat of the electrical components, and the waste heat of the battery module, the heating efficiency can be improved when heating the vehicle interior, and the overall driving distance of the vehicle can be increased by effectively regulating the temperature of the battery module to achieve the optimal performance of the battery module.

[0033] In addition, according to the present disclosure, the temperature of the electrical components and the battery module can be effectively regulated through valve control, so the overall market competitiveness of the vehicle can be improved.

[0034] In addition, according to the present disclosure, due to the simplification of the entire system, the overall manufacturing cost and weight can be reduced, and the space utilization rate can be improved by minimizing the number of components. Description of the Drawings

[0049] Figure 1 It is a block diagram of a heat pump system for a vehicle according to an embodiment.

[0050] A heat pump system for a vehicle according to an embodiment can selectively exchange heat between a coolant and the thermal energy generated from a refrigerant during refrigerant condensation and evaporation, and can perform heating inside the vehicle by using a high-temperature coolant.

[0051] In addition, the heat pump system can heat the interior of the vehicle by selectively using ambient air heat, waste heat of the electrical component 13, and waste heat of the battery module 22, thereby improving the heating efficiency of the vehicle. The heat pump system can effectively regulate the temperature of the battery module 22 so that the battery module 22 has optimal performance, thereby increasing the overall driving distance of the vehicle.

[0052] This heat pump system can be applied to hybrid vehicles or electric vehicles.

[0053] Referring Figure 1 , the heat pump system may include a valve module 2, a first pipeline 11, a second pipeline 21, and a third pipeline 31.

[0054] In one embodiment, the valve module 2 may include a plurality of ports through which coolant is introduced or discharged, and the flow movement of the introduced coolant can be controlled.

[0055] The first pipeline 11 may have a first end and a second end connected to the valve module 2, and coolant may flow through the first pipeline 11. A radiator 12 and electrical components 13 may be provided in the first pipeline 11.

[0056] The radiator 12 may be provided at the front of the vehicle, and a cooling fan may be provided on the downstream side of the radiator 12. Therefore, the radiator 12 can cool the coolant through the operation of the cooling fan and heat exchange with ambient air.

[0057] Therefore, the coolant cooled by the radiator 12 can circulate along the first pipeline 11 to flow to the valve module 2.

[0058] In one embodiment, the electrical components 13 may include a power control unit (EPCU) having at least one motor, an on-vehicle charger (OBC), etc.

[0059] When the vehicle is running, the power control device can generate heat, and the charger can generate heat when charging the battery module 22.

[0060] That is, when heating the vehicle interior, when the waste heat of the electrical components 13 is to be recovered, the heat generated from the power control device can be recovered, and the heat generated from the charger can be recovered when charging the battery module 22.

[0061] In one embodiment, the second pipeline 21 may have a first end and a second end connected to the valve module 2, and coolant may flow through the second pipeline 21. A battery module 22 and a cooler 106 may be provided in the second pipeline 21. In addition, an autonomous driving controller 23 and a first water pump 24 may be further provided in the second pipeline 21.

[0062] Here, the autonomous driving controller 23 may be provided in the second pipeline 21 between the battery module 22 and the cooler 106. In addition, the first water pump 24 may be an electric water pump.

[0063] The selectively expanded refrigerant can be introduced into the cooler 106. To cool the battery module 22 and the autonomous driving controller 23, or to heat the vehicle interior, the cooler 106 can operate to recover heat from the coolant, the temperature of which is increased by at least one of ambient air heat, waste heat of the electrical component 13, and waste heat of the battery module 22.

[0064] In addition, the third pipeline 31 can have a first end and a second end connected to the valve module 2, and the coolant can flow through the third pipeline 31. The second water pump 34, the condenser 102, and the heating core 40 can be disposed in the third pipeline 31.

[0065] Here, the second water pump 34 can be an electric water pump.

[0066] In one embodiment, the condenser 102 can be connected to a compressor (not shown) through a refrigerant pipeline. The condenser 102 can condense the refrigerant through heat exchange between the refrigerant and the coolant circulating in the third pipeline 31.

[0067] That is, the condenser 102 can condense the introduced refrigerant by exchanging heat with the coolant, and can increase the temperature of the coolant by supplying the thermal energy generated when condensing the refrigerant to the coolant.

[0068] The condenser 102 can be a water-cooled heat exchanger into which the coolant is introduced.

[0069] Here, the electric heater 103 can be further disposed in the third pipeline 31. The electric heater 103 can be disposed in the third pipeline 31 separately from the condenser 102, or can be integrally formed with the condenser 102.

[0070] The electric heater 103 can selectively heat the coolant introduced through the third pipeline 31, thereby increasing the temperature of the coolant.

[0071] Therefore, the third pipeline 31 can be connected to the condenser 102 and the electric heater 103 such that the coolant can pass through the condenser 102 and the electric heater 103 in sequence.

[0072] Although not shown in the drawings, for cooling the vehicle interior, the heat pump system can further include an evaporator for cooling the ambient air. The expanded refrigerant can be selectively supplied to the evaporator.

[0073] That is, when it is necessary to cool the vehicle interior, or when it is necessary to dehumidify while heating the vehicle interior, the expanded refrigerant can be introduced into the evaporator.

[0074] In addition, as described above, the refrigerant can be selectively introduced into the condenser 102, the evaporator, and the cooler 106.

[0075] Therefore, the condenser 102 and the cooler 106 can selectively exchange heat between the thermal energy generated by the condensation and evaporation of the refrigerant and the coolant flowing through the third pipe 31 and the second pipe 21.

[0076] More specifically, according to the selected vehicle mode, by operating the valve module 2 and the second water pump 34, the high-temperature coolant that has undergone heat exchange in the condenser 102 can be introduced into the heating core 40 provided in the third pipe 31.

[0077] In one embodiment, the heating core 40 and the evaporator can be provided in a heating, ventilation, and air conditioning (HVAC) module (not shown).

[0078] That is, by operating a blower-fan (not shown), the ambient air introduced into the vehicle interior can be converted to a high-temperature state or a low-temperature state while exchanging heat with the high-temperature coolant introduced into the heating core 40 or the refrigerant introduced into the evaporator.

[0079] The high-temperature or low-temperature ambient air can be introduced into the vehicle interior to cool or heat the vehicle interior.

[0080] In one embodiment, the valve module 2 can be a six-way valve having six ports through which the coolant is introduced or discharged. The valve module 2 will be described in more detail below.

[0081] The valve module 2 can include a first port 2a, a second port 2b, a third port 2c, a fourth port 2d, a fifth port 2e, and a sixth port 2f.

[0082] In one embodiment, the first end of the first pipe 11 can be connected to the first port 2a of the valve module 2. The second end of the first pipe 11 can be connected to the second port 2b of the valve module 2.

[0083] In another embodiment, the first end of the second pipe 21 can be connected to the third port 2c of the valve module 2. The second end of the second pipe 21 can be connected to the fourth port 2d of the valve module 2.

[0084] In addition, the first end of the third pipe 31 can be connected to the fifth port 2e of the valve module 2. The second end of the third pipe 31 can be connected to the sixth port 2f of the valve module 2.

[0085] Although the valve module 2 is a six-way valve forming six ports through which the coolant is introduced or discharged, the present disclosure is not limited thereto. For example, the valve module 2 can include more ports such that separate components for circulating the coolant can be connected.

[0086] The valve module 2 can operate according to at least one mode of adjusting at least one of the temperature inside the vehicle and the temperature of the battery module 22 to selectively interconnect the first pipeline, the second pipeline, and the third pipeline (11, 21, and 31). The valve module 2 controls the flow of the coolant. That is, the valve module 2 can selectively interconnect at least two of the first pipeline, the second pipeline, and the third pipeline (11, 21, and 31) to control the flow of the coolant based on at least one mode.

[0087] The at least one mode may include a first mode to a sixth mode.

[0088] In the first mode, the electrical components 13 and the battery module 22 can be cooled by using the coolant cooled at the radiator 12.

[0089] In the second mode, the interior of the vehicle can be cooled, and the electrical components 13 and the battery module 22 can be cooled by using the coolant cooled at the radiator 12.

[0090] In the third mode, the interior of the vehicle can be cooled, the electrical components 13 can be cooled by using the coolant cooled at the radiator 12, and the battery module 22 can be cooled by using the coolant cooled at the cooler 106.

[0091] In the fourth mode, the interior of the vehicle can be heated, and the battery module 22 can be heated while recovering the heat of the ambient air and the waste heat of the electrical components 13.

[0092] In the fifth mode, the interior of the vehicle can be heated, and the heat of the ambient air, the waste heat of the electrical components 13, and the waste heat of the battery module 22 can be recovered.

[0093] In addition, in the sixth mode, the interior of the vehicle can be heated by using the electric heater 103, and the waste heat of the coolant can be recovered while heating the battery module 22.

[0094] Hereinafter, with reference to Figures 2 - 7 The operation and actions of each mode of the heat pump system for a vehicle according to the embodiment configured as described above will be described in detail.

[0095] In a heat pump system for a vehicle according to an embodiment, with reference to Figure 2 The operation according to the first mode will be described, which is for cooling the electrical components 13 and the battery module 22 by using the coolant cooled at the radiator 12.

[0096] Figure 2 It is an operation diagram according to the first mode in a heat pump system for a vehicle according to an embodiment.

[0097] With reference to Figure 2, the refrigerant may not be supplied to the condenser 102, the evaporator, and the cooler 106.

[0098] In addition, the first pipe 11 can be connected to the second pipe 21 by the operation of the valve module 2, so that the coolant cooled at the radiator 12 can be introduced into the electrical component 13 and the battery module 22.

[0099] Meanwhile, the third pipe 31 can be closed by the operation of the valve module 2.

[0100] Therefore, by the operation of the first water pump 24, the coolant cooled at the radiator 12 can be introduced into the first port 2a of the valve module 2 along the first pipe 11.

[0101] By the operation of the valve module 2, the coolant introduced into the first port 2a of the valve module 2 can be discharged to the second pipe 21 connected to the fourth port 2d of the valve module 2.

[0102] The coolant discharged to the second pipe 21 can sequentially pass through the battery module 22, the autonomous driving controller 23, and the cooler 106. Thereafter, the coolant can be introduced into the third port 2c of the valve module 2.

[0103] The coolant introduced into the third port 2c of the valve module 2 can be discharged to the first pipe 11 connected to the second port 2b of the valve module 2 by the operation of the valve module 2.

[0104] The coolant discharged to the first pipe 11 can pass through the electrical component 13 along the first pipe 11 and then can be introduced into the radiator 12.

[0105] That is, in the first mode, the first pipe 11 and the second pipe 21 can form a closed loop through which the coolant circulates by the operation of the valve module 2.

[0106] In this state, the coolant can circulate along the interconnected first pipe 11 and second pipe 21 by the operation of the first water pump 24.

[0107] The coolant cooled by the radiator 12 can circulate along the first pipe 11 and the second pipe 21 while repeatedly performing the above operations.

[0108] More specifically, the coolant cooled at the radiator 12 can first pass through the battery module 22 along the second pipe 21, and then can pass through the autonomous driving controller 23. Thereafter, the coolant can be led from the second pipe 21 to the electrical component 13 along the first pipe 11 connected by the valve module 2.

[0109] Therefore, the electrical component 13, the battery module 22, and the autonomous driving controller 23 can be effectively cooled by the coolant cooled by the radiator 12.

[0110] In a heat pump system for a vehicle according to an embodiment, refer to Figure 3 Describe the operation according to the second mode, which is used to cool the vehicle interior and cool the electrical component 13 and the battery module 22 by using the coolant cooled by the radiator 12.

[0111] Figure 3 It is an operation diagram according to the second mode in a heat pump system for a vehicle according to an embodiment.

[0112] Refer to Figure 3 , the refrigerant can circulate through the condenser 102 and the evaporator. At this time, the refrigerant may not be supplied to the cooler 106, and the expanded refrigerant may be supplied to the evaporator.

[0113] In addition, the first pipeline 11, the second pipeline 21, and the third pipeline 31 can be interconnected through the operation of the valve module 2, so that the coolant cooled by the radiator 12 can be introduced into the electrical component 13, the battery module 22, and the condenser 102.

[0114] Therefore, through the operation of the first water pump 24, the coolant cooled by the radiator 12 can be introduced into the first port 2a of the valve module 2 along the first pipeline 11.

[0115] Through the operation of the valve module 2, the coolant introduced into the first port 2a of the valve module 2 can be discharged to the second pipeline 21 connected to the fourth port 2d of the valve module 2.

[0116] The coolant discharged to the second pipeline 21 can sequentially pass through the battery module 22, the autonomous driving controller 23, and the cooler 106. Thereafter, the coolant can be introduced into the third port 2c of the valve module 2.

[0117] Through the operation of the valve module 2 and the second water pump 34, the coolant introduced into the third port 2c of the valve module 2 can be discharged to the third pipeline 31 connected to the sixth port 2f of the valve module 2.

[0118] The coolant discharged to the third pipeline 31 can sequentially pass through the condenser 102, the electric heater 103, and the heating core 40 along the third pipeline 31. Here, the electric heater 103 may not work.

[0119] The coolant flowing through the third pipeline 31 can be introduced into the fifth port 2e of the valve module 2.

[0120] The coolant introduced into the fifth port 2e of the valve module 2 can be discharged to the second port 2b of the valve module 2 through the operation of the valve module 2 and supplied to the electrical component 13 along the first pipeline 11.

[0121] In the second mode, the first pipeline 11, the second pipeline 21, and the third pipeline 31 can form a closed loop through which the coolant circulates by the operation of the valve module 2.

[0122] In this state, the coolant can circulate along the interconnected first pipeline 11, second pipeline 21, and third pipeline 31 by the operation of the first water pump 24 and the second water pump 34.

[0123] That is, the coolant cooled at the radiator 12 can circulate along the first pipeline 11, second pipeline 21, and third pipeline 31 while repeatedly performing the above operations.

[0124] Therefore, the electrical component 13, the battery module 22, and the autonomous driving controller 23 can be effectively cooled by the coolant cooled at the radiator 12.

[0125] In a heat pump system for a vehicle according to an embodiment, refer to Figure 4 Describe the operation according to the third mode. In the third mode, the interior of the vehicle and the electrical component 13 are cooled using the coolant cooled at the radiator 12, and the battery module 22 is cooled using the coolant cooled at the cooler 106.

[0126] Figure 4 It is an operation diagram according to the third mode in a heat pump system for a vehicle according to an embodiment.

[0127] Refer to Figure 4 , the refrigerant can circulate through the condenser 102, the evaporator, and the cooler 106. At this time, the expanded refrigerant can be supplied to the evaporator and the cooler 106 respectively.

[0128] In addition, the first pipeline 11 can be connected to the third pipeline 31 by the operation of the valve module 2, so that the coolant cooled at the radiator 12 can be introduced into the electrical component 13 and the condenser 102.

[0129] Therefore, by the operation of the second water pump 34, the coolant cooled at the radiator 12 can be introduced into the first port 2a of the valve module 2 along the first pipeline 11.

[0130] By the operation of the valve module 2, the coolant introduced into the first port 2a of the valve module 2 can be discharged to the third pipeline 31 connected to the sixth port 2f of the valve module 2.

[0131] The coolant discharged to the third pipeline 31 can sequentially pass through the condenser 102 and the electric heater 103, and then through the heating core 40. Here, the condenser 102 can condense the refrigerant by using the coolant flowing along the third pipeline 31. At this time, the electric heater 103 does not operate.

[0132] Then, the coolant that has passed through the heating core 40 can be introduced along the third pipeline 31 into the fifth port 2e of the valve module 2.

[0133] The coolant introduced into the fifth port 2e of the valve module 2 can be discharged to the second port 2b of the valve module 2 and supplied along the first pipeline 11 to the electrical component 13.

[0134] Therefore, the electrical component 13 can be effectively cooled by the coolant cooled at the radiator 12.

[0135] That is, in the third mode, the first pipeline 11 and the third pipeline 31 can form a closed loop through which the coolant circulates by the operation of the valve module 2.

[0136] In this state, the coolant can circulate along the interconnected first pipeline 11 and third pipeline 31 by the operation of the second water pump 34.

[0137] In addition, the second pipeline 21 can form an independent closed loop through which the coolant circulates by the operation of the valve module 2, so that the coolant cooled by heat exchange with the refrigerant when passing through the cooler 106 can be supplied to the battery module 22 and the autonomous driving controller 23.

[0138] That is, by the operation of the valve module 2, the coolant introduced into the third port 2c of the valve module 2 from the cooler 106 along the second pipeline 21 can be discharged to the second pipeline 21 connected to the fourth port 2d of the valve module 2.

[0139] The coolant discharged to the second pipeline 21 can pass through the battery module 22 and the autonomous driving controller 23, and then can be introduced back to the cooler 106. The coolant that has passed through the cooler 106 can be introduced into the third port 2c of the valve module 2 along the second pipeline 21.

[0140] Then, the coolant introduced into the third port 2c of the valve module 2 can be discharged to the second pipeline 21 connected to the fourth port 2d of the valve module 2 by the operation of the valve module 2.

[0141] That is, in the third mode, the second pipeline 21 can form another closed loop through which the coolant circulates by the operation of the valve module 2.

[0142] In this state, the coolant can circulate along the second pipeline 21 by the operation of the first water pump 24.

[0143] At this time, the cooler 106 can cool the coolant by exchanging heat between the coolant introduced via the second pipeline 21 and the refrigerant.

[0144] Therefore, the coolant cooled at the cooler 106 can effectively cool the battery module 22 and the autonomous driving controller 23 while circulating along the second pipeline 21.

[0145] In addition, the evaporator can cool the ambient air by exchanging heat with the supplied refrigerant and can evaporate the refrigerant.

[0146] In one embodiment, an open / close door (not shown) can be provided between the evaporator and the heating core 40. The open / close door can close the side facing the heating core 40 so that the ambient air cooled when passing through the evaporator can be directly introduced into the vehicle.

[0147] In this state, through the operation of a blower-fan (not shown), the ambient air introduced into the vehicle interior can be cooled while exchanging heat with the low-temperature refrigerant supplied to the evaporator. Thereafter, the cooled ambient air can be directly introduced into the vehicle interior, thereby effectively cooling the vehicle interior.

[0148] In addition, when dehumidification is required while cooling the vehicle interior, the open / close door (not shown) can open the part passing through the heating core 40 so that the ambient air cooled when passing through the evaporator can pass through the heating core 40.

[0149] Therefore, through the operation of a blower-fan (not shown), the ambient air introduced into the vehicle interior can be cooled while exchanging heat with the low-temperature refrigerant supplied to the evaporator. Thereafter, the cooled ambient air can be dehumidified while passing through the heating core 40 and introduced into the vehicle interior, thereby smoothly cooling and dehumidifying the vehicle interior.

[0150] In a heat pump system for a vehicle according to an embodiment, refer to Figure 5 Describe the operation according to the fourth mode, which is used to heat the vehicle interior and the battery module 22 while recovering the heat of the ambient air and the waste heat of the electrical component 13.

[0151] Figure 5 is an operation diagram according to the fourth mode in a heat pump system for a vehicle according to an embodiment.

[0152] Refer to Figure 5 , the refrigerant can circulate through the condenser 102 and the cooler 106. At this time, the expanded refrigerant can be supplied to the cooler 106.

[0153] In addition, through the operation of the valve module 2, the first pipeline 11 can be connected to the third pipeline 31 so that the coolant that has passed through the radiator 12 and the electrical component 13 can be introduced into the condenser 102.

[0154] Meanwhile, the third pipeline 31 can be connected to the second pipeline 21 through the operation of the valve module 2, so that the coolant whose temperature has risen when passing through the condenser 102 can be introduced into the battery module 22 and the cooler 106.

[0155] Therefore, the coolant can recover the ambient air heat through heat exchange with the ambient air when passing through the radiator 12, and can absorb the waste heat from the electrical component 13 to increase its temperature.

[0156] The coolant whose temperature has risen can be introduced into the second port 2b of the valve module 2 along the first pipeline 11 through the operation of the second water pump 34.

[0157] Through the operation of the valve module 2, the coolant introduced into the second port 2b of the valve module 2 can be discharged to the third pipeline 31 connected to the sixth port 2f of the valve module 2.

[0158] The coolant discharged to the third pipeline 31 can sequentially pass through the condenser 102 and the electric heater 103. Here, the condenser 102 can condense the refrigerant by using the coolant flowing along the third pipeline 31.

[0159] At this time, while condensing the refrigerant at the condenser 102, the temperature of the coolant can rise. The coolant whose temperature has risen when passing through the condenser 102 can be introduced into the heating core 40 along the third pipeline 31.

[0160] In this state, through the operation of a blower-fan (not shown), the ambient air introduced into the vehicle interior can be converted to a high-temperature state while exchanging heat with the high-temperature coolant supplied to the heating core 40. Thereafter, the ambient air in the high-temperature state can be introduced into the vehicle interior, thereby heating the vehicle interior.

[0161] In addition, the coolant that has passed through the heating core 40 can be introduced into the fifth port 2e of the valve module 2 along the third pipeline 31.

[0162] Through the operation of the valve module 2 and the first water pump 24, the coolant introduced into the fifth port 2e of the valve module 2 can be discharged to the second pipeline 21 connected to the fourth port 2d of the valve module 2.

[0163] The coolant discharged to the second pipeline 21 can increase the temperature of the battery module 22 when passing through the battery module 22. Through this operation, when supplying the coolant with an increased temperature, the battery module 22 can effectively increase its temperature.

[0164] The coolant that has passed through the battery module 22 and the autonomous driving controller 23 through the operation of the first water pump 24 can be introduced into the cooler 106 along the second pipeline 21.

[0165] The coolant that has increased in temperature by recovering the heat of ambient air in the radiator 12 and absorbing the waste heat from the electrical component 13 can raise the temperature of the refrigerant supplied to the cooler 106.

[0166] That is, the cooler 106 can be used to recover the heat of ambient air and the waste heat of the electrical component 13 by exchanging heat between the coolant and the refrigerant, thereby raising the temperature of the refrigerant.

[0167] Then, the coolant that has passed through the cooler 106 can be introduced into the third port 2c of the valve module 2 along the second pipeline 21.

[0168] The coolant introduced into the third port 2c of the valve module 2 can be discharged to the first pipeline 11 connected to the first port 2a of the valve module 2 through the operation of the valve module 2.

[0169] The coolant discharged to the first pipeline 11 can pass through the radiator 12 and the electrical component 13 in sequence, and then flow back to the valve module 2, thereby repeatedly performing the above process.

[0170] In the fourth mode, the first pipeline 11, the second pipeline 21, and the third pipeline 31 can form a closed loop through which the coolant circulates through the operation of the valve module 2.

[0171] In this state, the coolant can circulate along the interconnected first pipeline 11, third pipeline 31, and second pipeline 21 through the operation of the first water pump 24 and the second water pump 34.

[0172] That is, in the heat pump system according to the present embodiment, the cooler 106 absorbs the heat of ambient air and the waste heat of the electrical component 13 and uses it to raise the temperature of the refrigerant, thereby heating the interior of the vehicle, enabling the power consumption of the compressor to be reduced and the heating efficiency to be improved.

[0173] In addition, when it is necessary to heat the battery module 22, the heat pump system can supply the coolant whose temperature has increased when passing through the condenser 102 to the battery module 22, thereby effectively raising the temperature of the battery module 22.

[0174] When dehumidification is required while heating the interior of the vehicle, the expanded refrigerant can be supplied to the evaporator.

[0175] At the same time, an open / close door (not shown) can open a part passing through the heating core 40, so that the ambient air cooled when passing through the evaporator can pass through the heating core 40.

[0176] Accordingly, the ambient air introduced into the vehicle interior can be dehumidified while exchanging heat with the low-temperature refrigerant supplied to the evaporator through the operation of a blower-fan (not shown). Thereafter, the dehumidified ambient air can be converted to a high-temperature state when passing through the heating core 40 and then introduced into the vehicle interior, thereby smoothly heating and dehumidifying the vehicle interior.

[0177] In a heat pump system for a vehicle according to an embodiment, refer to Figure 6 Describe the operation according to the fifth mode, which is for heating the vehicle interior and recovering the waste heat of the ambient air, the waste heat of the electrical component 13, and the waste heat of the battery module 22.

[0178] Figure 6 is an operation diagram according to the fifth mode in a heat pump system for a vehicle according to an embodiment.

[0179] Refer to Figure 6 , the refrigerant can circulate through the condenser 102 and the cooler 106. At this time, the expanded refrigerant can be supplied to the cooler 106.

[0180] In addition, the first pipeline 11 can be connected to the second pipeline 21 through the operation of the valve module 2, so that the coolant that has passed through the radiator 12, the electrical component 13, and the battery module 22 can be introduced into the cooler 106.

[0181] Accordingly, the coolant can recover the ambient air heat through heat exchange with the ambient air when passing through the radiator 12, and can absorb the waste heat from the electrical component 13 to increase its temperature.

[0182] The coolant with an increased temperature can be introduced into the second port 2b of the valve module 2 along the first pipeline 11 through the operation of the first water pump 24.

[0183] Through the operation of the valve module 2, the coolant introduced into the second port 2b of the valve module 2 can be discharged to the second pipeline 21 connected to the fourth port 2d of the valve module 2.

[0184] The coolant discharged to the second pipeline 21 can pass through the battery module 22 and the autonomous driving controller 23. Here, the coolant can absorb the waste heat from the battery module 22 when passing through the battery module 22, thereby further increasing its temperature.

[0185] In this state, the coolant can be supplied to the cooler 106 along the second pipeline 21. Accordingly, the ambient air heat recovered at the radiator 12, the waste heat generated at the electrical component 13, and the waste heat generated at the battery module 22 can increase the temperature of the refrigerant supplied to the cooler 106.

[0186] That is, the cooler 106 can be used to recover the ambient air heat, the waste heat of the electrical component 13, and the waste heat of the battery module 22 by exchanging heat between the coolant and the refrigerant, thereby increasing the temperature of the refrigerant.

[0187] Then, the coolant that has passed through the cooler 106 can be introduced into the third port 2c of the valve module 2 along the second pipeline 21.

[0188] Then, the coolant introduced into the third port 2c of the valve module 2 can be discharged to the first pipeline 11 connected to the first port 2a of the valve module 2 through the operation of the valve module 2.

[0189] The coolant discharged to the first pipeline 11 can sequentially pass through the radiator 12 and the electrical component 13, and then flow back to the valve module 2, thereby repeatedly performing the above process.

[0190] That is, in the fifth mode, the first pipeline 11 and the second pipeline 21 can form a closed loop through which the coolant circulates through the operation of the valve module 2.

[0191] In this state, the coolant can circulate along the interconnected first pipeline 11 and second pipeline 21 through the operation of the first water pump 24.

[0192] In addition, the third pipeline 31 can form an independent closed loop through the operation of the valve module 2, so that the coolant can sequentially pass through the condenser 102 and the heating core 40 along the third pipeline 31.

[0193] The coolant introduced into the fifth port 2e of the valve module 2 through the third pipeline 31 can be discharged to the sixth port 2f of the valve module 2 through the operation of the second water pump 34 and the valve module 2.

[0194] Then, the coolant circulating along the third pipeline 31 can sequentially pass through the condenser 102 and the electric heater 103. Here, the condenser 102 can condense the refrigerant by using the coolant flowing along the third pipeline 31.

[0195] At this time, while condensing the refrigerant at the condenser 102, the temperature of the coolant can increase. The coolant whose temperature has increased when passing through the condenser 102 can be introduced into the heating core 40 along the third pipeline 31.

[0196] In this state, through the operation of a blower - fan (not shown), the ambient air introduced into the vehicle interior can be converted to a high - temperature state while exchanging heat with the high - temperature coolant supplied to the heating core 40.

[0197] Then, the ambient air in the high - temperature state can be introduced into the vehicle interior, thereby achieving heating of the vehicle interior.

[0198] In the heat pump system according to this embodiment, the interior of the vehicle is heated by the heat of the ambient air and the waste heat of the electrical component 13, and the waste heat of the battery module 22 is absorbed by the cooler 106 and used to increase the temperature of the refrigerant, so that the power consumption of the compressor can be reduced and the heating efficiency can be improved.

[0199] In addition, the coolant that has passed through the heating core 40 can flow along the third pipeline 31 and then flow into the fifth port 2e of the valve module 2, thereby repeatedly performing the above process.

[0200] When dehumidification is required while heating the interior of the vehicle, the expanded refrigerant can be supplied to the evaporator.

[0201] Meanwhile, an open / close door (not shown) can open a part passing through the heating core 40, so that the ambient air cooled when passing through the evaporator can pass through the heating core 40.

[0202] Therefore, the ambient air introduced into the interior of the vehicle can be dehumidified while exchanging heat with the low-temperature refrigerant supplied to the evaporator through the operation of a blower-fan (not shown).

[0203] Then, the dehumidified ambient air can be converted to a high-temperature state when passing through the heating core 40 and then introduced into the interior of the vehicle, thereby smoothly heating and dehumidifying the interior of the vehicle.

[0204] In addition, in the heat pump system for a vehicle according to an embodiment, refer to Figure 7 Describe the operation according to the sixth mode, which heats the interior of the vehicle by using the electric heater 103 and recovers the waste heat of the coolant while heating the battery module 22.

[0205] Figure 7 is the operation diagram according to the sixth mode in the heat pump system for a vehicle according to an embodiment.

[0206] Refer to Figure 7 , the refrigerant can circulate through the condenser 102 and the cooler 106. At this time, the refrigerant may not be supplied to the evaporator, and the expanded refrigerant can be supplied to the cooler 106.

[0207] Here, the first pipeline 11 can be closed by the operation of the valve module 2.

[0208] In this state, the third pipeline 31 can be connected to the second pipeline 21 by the operation of the valve module 2, so that the coolant that has passed through the condenser 102 and the electric heater 103 can sequentially pass through the battery module 22 and the cooler 106.

[0209] Here, the first water pump 24, the second water pump 34, and the electric heater 103 can operate.

[0210] Therefore, the coolant whose temperature has risen when passing through the electric heater 103 can pass through the heating core 40 along the third pipeline 31, and then can be introduced into the fifth port 2e of the valve module 2.

[0211] Through the operation of the valve module 2, the coolant introduced into the fifth port 2e of the valve module 2 can be discharged into the second pipeline 21 connected to the fourth port 2d of the valve module 2.

[0212] The coolant discharged into the second pipeline 21 can raise the temperature of the battery module 22 when passing through the battery module 22.

[0213] Then, the coolant that has passed through the battery module 22 and the autonomous driving controller 23 can be supplied to the cooler 106 along the second pipeline 21. At this time, the cooler 106 can increase the temperature of the refrigerant by using the remaining waste heat in the coolant that has passed through the battery module 22.

[0214] That is, the cooler 106 can be used to recover the waste heat of the coolant by exchanging heat between the coolant and the refrigerant, thereby increasing the temperature of the refrigerant.

[0215] The refrigerant evaporated at the cooler 106 can be introduced into the compressor, and the refrigerant compressed at the compressor can be supplied to the condenser 102. Therefore, the refrigerant supplied to the condenser 102 can increase the temperature of the coolant while exchanging heat with the coolant introduced through the third pipeline 31.

[0216] In addition, the coolant that has passed through the cooler 106 can be introduced into the third port 2c of the valve module 2 along the second pipeline 21.

[0217] Through the operation of the valve module 2, the coolant introduced into the third port 2c of the valve module 2 can be discharged into the third pipeline 31 connected to the sixth port 2f of the valve module 2.

[0218] The coolant discharged into the third pipeline 31 can pass through the condenser 102 and the electric heater 103, and then can be introduced into the heating core 40 along the third pipeline 31.

[0219] In addition, the coolant that has passed through the heating core 40 can flow back to the valve module 2 along the third pipeline 31, thereby repeatedly performing the above process.

[0220] That is, in the sixth mode, the second pipeline 21 and the third pipeline 31 can form a closed loop through which the coolant circulates through the operation of the valve module 2.

[0221] In this state, the coolant can circulate along the interconnected second pipeline 21 and third pipeline 31 through the operation of the first and second water pumps 24 and 34.

[0222] Here, the electric heater 103 can heat the introduced coolant. At the same time, the condenser 102 can heat the introduced coolant together with the electric heater 103.

[0223] That is, in order to increase the temperature of the coolant, the electric heater 103 can play a main role, and the condenser 102 can play an auxiliary role. Through this operation, the temperature of the coolant can be increased.

[0224] The coolant with an increased temperature can be introduced into the heating core 40 along the third pipeline 31.

[0225] In this state, through the operation of a blower - fan (not shown), the ambient air introduced into the vehicle interior can be converted to a high - temperature state while exchanging heat with the high - temperature coolant supplied to the heating core 40. Thereafter, the ambient air in the high - temperature state can be introduced into the vehicle interior, thereby achieving heating of the vehicle interior.

[0226] In addition, the heat pump system can supply the coolant whose temperature has increased when passing through the electric heater 103 to the battery module 22 to heat the battery module 22, thereby effectively increasing the temperature of the battery module 22.

[0227] In addition, the heat pump system can recover the waste heat of the coolant that heats the battery module 22 by the cooler 106, and can minimize the use of the electric heater 103 by using the condenser 102 as an auxiliary device for heating the coolant.

[0228] As described above, when applying the heat pump system for a vehicle according to an embodiment, by selectively exchanging heat between the thermal energy generated from the refrigerant during condensation and evaporation and the coolant, and by using the high - temperature coolant after heat exchange to heat the vehicle interior, the entire system can be simplified, and the layout of the connecting pipes through which the refrigerant circulates can be simplified.

[0229] In addition, according to the present disclosure, in order to heat the vehicle interior, the heating efficiency of the vehicle can be improved by selectively using the ambient air heat, the waste heat of the electrical component 13, and the waste heat of the battery module 22, and the battery module 22 can exhibit optimal performance through effective temperature regulation of the battery module 22, thereby increasing the overall driving distance of the vehicle.

[0230] In addition, according to the present disclosure, through the control valve module 2, the temperatures of the electrical component 13 and the battery module 22 can be effectively regulated, thereby improving the overall market competitiveness of the vehicle.

[0231] In addition, according to the present disclosure, due to the simplification of the entire system, the overall manufacturing cost and weight can be reduced, and the space utilization rate can be improved by minimizing the number of components.
