DETAILED DESCRIPTION

[0026] In view of the safety, comfort and economy requirements of new energy electric vehicles, while fully considering the energy flow of batteries, motors and passenger compartments, it is also necessary to refine the layout of functional requirements, such as heat dissipation, heat storage, and waste heat utilization of motors, heat dissipation, heating, and waste heat utilization of batteries, and decoupling and coupling of passenger compartment cooling, heating, dehumidification, defrosting, and defogging. In this way, the number of components corresponding to the vehicle thermal management system has also increased significantly, and in the existing technology, the integration of the components of the thermal management system is not high, or the highly integrated solutions will have the problem of cross-heating, resulting in a decrease in heat utilization.

[0027] In order to solve the problem that existing thermal management systems are difficult to simultaneously meet the requirements of high integration and low cross-heat, the present application provides a thermal management integrated module and a new energy vehicle.

[0028] See also Figure 1-Figure 7The thermal management integrated module includes a refrigerant side flow channel plate 100, a coolant side flow channel plate 200, a refrigerant side component 300, a coolant side component 400 and a chiller 500 (chiller). The coolant side component 400 is connected to the coolant side flow channel plate 200, and a plurality of first flow channels 210 are provided in the coolant side flow channel plate 200. The refrigerant side component 300 and the chiller 500 are respectively connected to the refrigerant side flow channel plate 100, and a plurality of second flow channels 120 are provided in the refrigerant side flow channel plate 100.

[0029] It should be noted that the refrigerant side assembly 300 includes a plurality of components.

[0030] Specifically, in one embodiment, if Figure 2 and Figure 6 As shown, the refrigerant side component 300 includes but is not limited to a gas-liquid separator 310 , a pressure and temperature sensor 320 , a temperature sensor 360 , an electronic expansion valve 330 , an electromagnetic stop valve 340 and a one-way valve 350 .

[0031] Furthermore, it should be noted that the number of the pressure and temperature sensor 320 , the electronic expansion valve 330 , the electromagnetic stop valve 340 , and the one-way valve 350 may be one or more.

[0032] Likewise, the coolant side assembly 400 also includes multiple components.

[0033] Specifically, in one embodiment, if Figure 3 and Figure 7 As shown, the coolant side assembly 400 includes but is not limited to a motor liquid pump 410, a battery liquid pump 420, a control valve 450, an integrated kettle 430 and a water temperature sensor 440. The motor liquid pump 410 and the battery liquid pump 420 can be connected to the integrated kettle 430 through the control valve 450. The water temperature sensor 440 is disposed on the coolant side flow channel plate 200 to detect the temperature of the medium (coolant) in the coolant side flow channel plate 200.

[0034] It should be pointed out that the integrated kettle 430 integrates the motor kettle and the battery kettle, making the entire structure more compact. While ensuring the reliability of the system, it can reduce the amount of coolant added to the thermal management integrated module, reduce the filling time, and further reduce costs. In addition, the integrated kettle 430 is connected to the coolant side flow channel plate 200 through a pair of interfaces (one inlet and one outlet), and the interface is designed at the inlet of the motor liquid pump 410. While ensuring the water replenishment function of the motor liquid pump 410, the degassing function of the coolant side component 400 and the coolant side flow channel plate 200 is realized through the extreme distribution of the one inlet and one outlet flow channels.

[0035] In one embodiment, if Figure 3 and Figure 7As shown, the motor liquid pump 410 , the battery liquid pump 420 , and the integrated water bottle 430 are distributed around the circumference of the control valve 450 .

[0036] The coolant side component 400 and the cooler 500 can be connected through the corresponding first circulation channel 210 to form multiple groups of coolant side heat exchange circulation open circuits, and the refrigerant side component 300 and the cooler 500 can be connected through the corresponding second circulation channel 120 to form multiple groups of refrigerant side heat exchange circulation open circuits. The refrigerant side heat exchange circulation open circuit and the coolant side heat exchange circulation open circuit can perform heat exchange through the cooler 500.

[0037] It should be noted that the refrigerant-side heat exchange cycle open circuit and the coolant-side heat exchange cycle open circuit can be respectively connected to the corresponding external heat exchange structure to be exchanged, so as to form a corresponding heat exchange cycle loop.

[0038] Furthermore, it should be noted that the external structure to be heat exchanged includes but is not limited to: a power battery 610 , a motor assembly 620 , a low-temperature radiator 630 , an evaporator 710 , an outdoor heat exchanger 720 , an indoor condenser 730 and a compressor 740 .

[0039] One end of the coolant side flow channel plate 200 away from the coolant side assembly 400 and one end of the refrigerant side flow channel plate 100 away from the refrigerant side assembly 300 are connected to form an integrated plate structure.

[0040] Specifically, in one embodiment, the coolant side flow channel plate 200 and the refrigerant side flow channel plate 100 are detachably connected.

[0041] Such a configuration is helpful to reduce the difficulty of disassembling and assembling the coolant side flow channel plate 200 and the refrigerant side flow channel plate 100 .

[0042] More specifically, the coolant side flow channel plate 200 is fixed to the refrigerant side flow channel plate 100 by bolts or clips, which reduces the assembly and fixing points of the coolant side flow channel plate 200 and the new energy vehicle, while shortening the passage between the coolant side component 400 and the refrigerant side component 300, making the overall structure more compact, extremely reducing costs and making the cabin layout more adaptable.

[0043] In another embodiment, the coolant side flow channel plate 200 and the refrigerant side flow channel plate 100 may also be welded or integrally formed.

[0044] The refrigerant side flow channel plate 100 is provided with a heat insulation groove 110 penetrating along its own thickness direction (along the direction from the refrigerant side flow channel plate 100 to the coolant side flow channel plate 200), and a heat insulation groove 110 is provided between at least some adjacent second circulation channels 120 to isolate the heat transfer between adjacent second circulation channels 120.

[0045] It can be understood that the circulation process of the refrigerant and the circulation process of the coolant are independent of each other. Therefore, by setting the refrigerant side flow channel plate 100 and the coolant side flow channel plate 200, and the coolant side component 400 is set on the side of the coolant side flow channel plate 200 away from the refrigerant side flow channel plate 100, and the refrigerant side component 300 is set on the side of the refrigerant side flow channel plate 100 away from the coolant side flow channel plate 200, it can effectively avoid the coolant side component 400 and the refrigerant side component 300 from interfering with each other during the setting process, thereby making the layout of the thermal management integrated module more reasonable.

[0046] Furthermore, since a plurality of first circulation channels 210 are provided in the coolant side flow channel plate 200, the coolant side assembly 400 and the cooler 500 can be connected through the corresponding first circulation channels 210 to form a plurality of coolant side heat exchange circulation open circuits, and a plurality of second circulation channels 120 are provided in the refrigerant side flow channel plate 100, the refrigerant side assembly 300 and the cooler 500 can be connected through the corresponding second circulation channels 120 to form a plurality of refrigerant side heat exchange circulation open circuits. Therefore, compared with the pipeline connection, such a setting greatly reduces the assembly volume of the entire thermal management integrated module and significantly improves the assembly integration of the thermal management integrated module.

[0047] Furthermore, since an insulation groove 110 is provided between at least some adjacent second circulation channels 120, and the insulation groove 110 passes through the refrigerant side flow channel plate 100, the heat transfer between the corresponding second circulation channels 120 will be greatly reduced, thereby effectively avoiding the heat conduction problem of the thermal management integrated module.

[0048] It should be noted that the temperature difference of the refrigerant under different working conditions on the refrigerant side is large, so heat conduction needs to be prevented, while the coolant temperature on the coolant side does not differ much, so there is no need for anti-heat conduction design.

[0049] In one embodiment, if Figure 7 As shown, the control valve 450 is a multi-way valve, and the multi-way valve is provided with a first connecting port 451, a second connecting port 452, a third connecting port 453, a fourth connecting port 454 and a fifth connecting port 455. The multi-way valve can be connected to the motor liquid pump 410 through the first connecting port 451, the multi-way valve can be connected to the outlet of the motor assembly 620 through the second connecting port 452, the multi-way valve can be connected to the battery liquid pump 420 through the third connecting port 453, the multi-way valve can be connected to the outlet of the power battery 610 through the fourth connecting port 454, and the multi-way valve can be connected to the inlet of the low-temperature radiator 630 through the fifth connecting port 455.

[0050] Such an arrangement can improve the thermal management efficiency of the power battery 610 and the motor assembly 620 .

[0051] Specifically, the various communication modes of the coolant side component 400 are as follows:

[0052] In mode one, the power battery 610 , the fourth connecting port 454 , the first connecting port 451 , the integrated kettle 430 , the motor liquid pump 410 , the motor assembly 620 , the second connecting port 452 , the third connecting port 453 , the battery liquid pump 420 , the cooler 500 and the power battery 610 can be connected in sequence.

[0053] At this time, the residual heat of the motor assembly 620 can be used to heat the power battery 610 .

[0054] Among them, a small part of the coolant enters the motor liquid pump 410 from the first connecting port 451 through the integrated kettle 430 to play a role in gas-liquid separation, and most of the coolant directly enters the motor liquid pump 410 from the first connecting port 451.

[0055] In mode two, the power battery 610, the fourth connecting port 454, the fifth connecting port 455, the low-temperature radiator 630, the integrated kettle 430, the motor liquid pump 410, the motor assembly 620, the second connecting port 452, the third connecting port 453, the battery liquid pump 420, the cooler 500 and the power battery 610 can be connected in sequence.

[0056] At this time, the low-temperature radiator 630 can be used to enable the power battery 610 to start a passive cooling mode.

[0057] Among them, a small part of the coolant enters the motor liquid pump 410 from the low-temperature radiator 630 through the integrated kettle 430 to play a role in gas-liquid separation, and most of the coolant directly enters the motor liquid pump 410 from the low-temperature radiator 630.

[0058] Mode three, the motor assembly 620, the second connecting port 452, the first connecting port 451, the integrated kettle 430, the motor liquid pump 410 and the motor assembly 620 are connected in sequence, and the power battery 610, the fourth connecting port 454, the third connecting port 453, the battery liquid pump 420, the cooler 500 and the power battery 610 are connected in sequence.

[0059] With this configuration, the motor assembly 620 enters a heat storage mode.

[0060] Among them, a small part of the coolant enters the motor liquid pump 410 from the first connecting port 451 through the integrated kettle 430 to play a role in gas-liquid separation, and most of the coolant directly enters the motor liquid pump 410 from the first connecting port 451.

[0061] In mode 4, the motor assembly 620, the second communication port 452, the fifth communication port 455, the low-temperature radiator 630, the integrated kettle 430, the motor fluid pump 410 and the motor assembly 620 can be connected in sequence to dissipate heat from the motor assembly 620 using the heat of the low-temperature radiator 630. In addition, the power battery 610, the fourth communication port 454, the third communication port 453, the battery fluid pump 420, the cooler 500 and the power battery 610 are connected in sequence.

[0062] With this configuration, the motor assembly 620 and the power battery 610 enter an independent heat dissipation mode.

[0063] Among them, a small part of the coolant enters the motor liquid pump 410 from the low-temperature radiator 630 through the integrated kettle 430 to play a role in gas-liquid separation, and most of the coolant directly enters the motor liquid pump 410 from the low-temperature radiator 630.

[0064] From the above, it can be seen that the matching design of the four-mode five-way water valve and the dual liquid pumps (motor liquid pump 410 and battery liquid pump 420), through the ultimate flow channel design inside the coolant side flow channel plate 200, makes the coolant circuit between the various parts as compact as possible, reduces the circulation distance of the coolant, reduces the flow resistance, and reduces the cost.

[0065] In one embodiment, if Figure 6 As shown, the pressure-temperature sensor 320 includes a first pressure-temperature sensor 321 and a second pressure-temperature sensor 322, the electronic expansion valve 330 includes a first expansion valve 331, a second expansion valve 332, a third expansion valve 333 and a fourth expansion valve 334, the electromagnetic stop valve 340 includes a first stop valve 341, a second stop valve 342 and a third stop valve 343, and the one-way valve 350 includes a first single valve 351, a second single valve 352 and a third single valve 353.

[0066] The various communication modes of the refrigerant side component 300 are as follows:

[0067] In mode one, the compressor 740, the third stop valve 343, the outdoor heat exchanger 720, the second single valve 352, the first pressure and temperature sensor 321, the second expansion valve 332, the cooler 500, the gas-liquid separator 310, the second pressure and temperature sensor 322 and the compressor 740 are connected in sequence.

[0068] It should be noted that, under the working condition of mode 1, the third stop valve 343 is in a normally open mode.

[0069] At this time, the refrigerant temperature can be lowered by dissipating heat to the refrigerant through the outdoor heat exchanger 720 and the throttling and pressure reduction effect of the second expansion valve 332, so that the refrigerant can dissipate heat to the power battery 610 through the cooler 500.

[0070] In mode two, the compressor 740, the third stop valve 343, the outdoor heat exchanger 720, the second single valve 352, the first pressure-temperature sensor 321, the third expansion valve 333, the evaporator 710, the temperature sensor 360, the first single valve 351, the gas-liquid separator 310, the second pressure-temperature sensor 322 and the inlet of the compressor 740 are connected in sequence.

[0071] It should be noted that, under the working condition of mode 2, the third stop valve 343 is in a normally open mode.

[0072] At this time, the temperature of the refrigerant can be reduced by dissipating heat from the refrigerant through the outdoor heat exchanger 720 and the throttling and pressure reduction effect of the third expansion valve 333, so that the refrigerant can cool the passenger compartment through the evaporator 710.

[0073] Mode three is a combination of mode one and mode two, that is, the refrigerant is divided into two paths through the outdoor heat exchanger 720 and enters the gas-liquid separator 310 respectively. At this time, the thermal management integrated module is in dual cooling mode.

[0074] Mode 4: The first path is the compressor 740, the outdoor heat exchanger 720, the third expansion valve 333, the evaporator 710, the gas-liquid separator 310 and the compressor 740 connected in sequence; the second path is the compressor 740, the indoor condenser 730, the third expansion valve 333, the evaporator 710, the gas-liquid separator 310 and the compressor 740 connected in sequence; the flow ratio of the first path and the second path is 1.5 / 1. At this time, the ambient temperature is 18°C ​​to 25°C, which is a cooling and dehumidification mode.

[0075] Mode 5: The first route is the compressor 740, the indoor condenser 730, the second expansion valve 332, the cooler 500, the gas-liquid separator 310 and the compressor 740 connected in sequence; the second route is the compressor 740, the indoor condenser 730, the third expansion valve 333, the evaporator 710, the gas-liquid separator 310 and the compressor 740 connected in sequence; the flow ratio of the first route and the second route is 1.2 / 1. At this time, the ambient temperature is 13°C to 20°C, which is the heating and dehumidification mode.

[0076] Mode six: the compressor 740, the indoor condenser 730, the third expansion valve 333, the evaporator 710, the gas-liquid separator 310 and the compressor 740 are connected in sequence; at this time, the ambient temperature is 7°C to 15°C, which is the heat pump heating and dehumidification mode.

[0077] Mode seven, the compressor 740, the second stop valve 342, the indoor condenser 730, the third single valve 353, the first pressure and temperature sensor 321, the first expansion valve 331, the outdoor heat exchanger 720, the first stop valve 341, the first single valve 351, the gas-liquid separator 310, the second pressure and temperature sensor 322 and the compressor 740 are connected in sequence.

[0078] It should be noted that under the operating condition of mode seven, the third stop valve 343 is a normally open valve, which is in the closed mode in this mode, the second stop valve 342 is a normally closed valve, which is in the open mode in this mode; the first stop valve 341 is a normally closed valve, which is in the open mode in this mode.

[0079] At this time, the high-temperature refrigerant releases a large amount of heat directly through the indoor condenser 730 to heat the passenger compartment.

[0080] Mode eight, the compressor 740, the fourth expansion valve 334, the gas-liquid separator 310, the second pressure-temperature sensor 322 and the inlet of the compressor 740 are connected in sequence, and the compressor 740, the second stop valve 342, the indoor condenser 730, the third single valve 353, the first pressure-temperature sensor 321, the second expansion valve 332, the gas-liquid separator 310, the second pressure-temperature sensor 322 and the compressor 740 are connected in sequence.

[0081] At this time, it is mainly used for heating in extremely low temperature environments. Specifically, when the ambient temperature is very low (less than -10°C), due to the physical properties of the refrigerant (mainly R134a), the outdoor heat exchanger 720 cannot obtain heat from the air or obtains less heat, and cannot meet the heating demand of the passenger compartment. At this time, the principle of hot gas bypass (that is, a loop in which the outlet of the compressor 740, the fourth expansion valve 334, the gas-liquid separator 310, the second pressure-temperature sensor 322 and the inlet of the compressor 740 are connected in sequence) can be used to provide an additional load, thereby increasing the flow rate of the compressor 740, and then increasing the electric power of the compressor 740, thereby meeting the corresponding heating demand.

[0082] In one embodiment, the inlet of the cooler 500 is sealed and connected to the end surface of the coolant-side flow channel plate 200 , and the outlet of the cooler 500 is designed on the cooler 500 .

[0083] Such an arrangement can reduce the end face sealing structure between the cooler 500 and the coolant side flow channel plate 200, and can also reduce an external interface of the coolant side flow channel plate 200, thereby saving layout space and achieving the ultimate optimization of space and cost.

[0084] In one embodiment, the coolant side flow channel plate 200 is injection molded and heated plate welded, or the coolant side flow channel plate 200 is injection molded and laser welded, and the refrigerant side flow channel plate 100 is forged and brazed, or the refrigerant side flow channel plate 100 is cast and laser welded.

[0085] Such a configuration is beneficial to improving the processing accuracy of the coolant side flow channel plate 200 and the refrigerant side flow channel plate 100, and reducing the processing difficulty of both.

[0086] In one embodiment, the refrigerant side component 300 and the cooler 500 are respectively detachably connected to the refrigerant side flow channel plate 100 , and the cooling liquid side component 400 is detachably connected to the cooling liquid side flow channel plate 200 .

[0087] Such an arrangement greatly facilitates the disassembly and assembly of the refrigerant side component 300, the coolant side component 400 and the cooler 500, and effectively improves the disassembly and assembly efficiency of the thermal management integrated module.

[0088] Specifically, in one embodiment, the integrated water bottle 430 and the coolant side flow channel plate 200 are connected by five-point bolts, and the connection between the integrated water bottle 430 and the coolant side flow channel plate 200 is radially sealed by an O-ring.

[0089] It should be noted that radial sealing means that the O-ring is clamped between the outer wall of the connecting protrusion of the integrated water bottle 430 and the inner wall of the connecting hole of the coolant side flow channel plate 200, and the inner ring of the O-ring seals the outer wall of the connecting protrusion of the integrated water bottle 430 along the radial direction of the connecting hole of the coolant side flow channel plate 200, and the outer ring of the O-ring seals the inner wall of the connecting hole of the coolant side flow channel plate 200 along the radial direction of the connecting hole of the coolant side flow channel plate 200.

[0090] And / or, the control valve 450 and the coolant side flow channel plate 200 are connected by four-point bolts, and the connection between the control valve 450 and the coolant side flow channel plate 200 is end-face sealed by an X-ring.

[0091] It should be noted that the end face sealing means that the end faces on both sides of the X-shaped ring squeeze and seal the control valve 450 and the coolant side flow channel plate 200 respectively.

[0092] And / or, the battery liquid pump 420 and the coolant side flow channel plate 200 are connected by four-point bolts, and the connection between the battery liquid pump 420 and the coolant side flow channel plate 200 is radially sealed by an O-ring.

[0093] And / or, the motor liquid pump 410 and the coolant side flow channel plate 200 are connected by four-point bolts, and the connection between the motor liquid pump 410 and the coolant side flow channel plate 200 is radially sealed by an O-ring.

[0094] And / or, the water temperature sensor 440 and the coolant side flow channel plate 200 are snap-connected, and the water temperature sensor 440 and the coolant side flow channel plate 200 are radially sealed by an O-ring.

[0095] It can be seen from the above that the coolant side flow channel plate 200 can not only realize the mutual connection of the coolant side components 400, but also can serve as a carrier of the coolant side components 400 to play a supporting role.

[0096] It should be noted that the above bolt connection can also be replaced by a clamping connection.

[0097] In one embodiment, the gas-liquid separator 310 and the refrigerant side flow channel plate 100 are connected by three-point bolts, and two interfaces of the gas-liquid separator 310 and the refrigerant side flow channel plate 100 are radially sealed by O-rings respectively.

[0098] And / or, the gas-liquid separator 310 and the second pressure-temperature sensor 322 are threadedly connected, and the gas-liquid separator 310 and the second pressure-temperature sensor 322 are radially sealed by an O-ring.

[0099] And / or, the cooler 500 and the refrigerant side flow channel plate 100 are connected by four-point bolts, and the two interfaces of the cooler 500 and the refrigerant side flow channel plate 100 are radially sealed by O-rings respectively.

[0100] And / or, the temperature sensor 360 and the refrigerant side flow channel plate 100 are threadedly connected, and the temperature sensor 360 and the refrigerant side flow channel plate 100 are radially sealed by an O-ring.

[0101] And / or, the first pressure-temperature sensor 321 and the refrigerant side flow channel plate 100 are threadedly connected, and the first pressure-temperature sensor 321 and the refrigerant side flow channel plate 100 are radially sealed by an O-ring.

[0102] And / or, the electromagnetic stop valve 340 and the refrigerant side flow channel plate 100 are threadedly connected, and two interfaces of the electromagnetic stop valve 340 and the refrigerant side flow channel plate 100 are radially sealed by O-rings respectively.

[0103] And / or, the one-way valve 350 and the refrigerant side flow channel plate 100 are threadedly connected, and two interfaces of the one-way valve 350 and the refrigerant side flow channel plate 100 are radially sealed by O-rings respectively.

[0104] And / or, the valve core part of the electronic expansion valve 330 is threadedly connected to the refrigerant side flow plate 100, and the valve core part of the electronic expansion valve 330 and the refrigerant side flow plate 100 are radially sealed by an O-ring; the coil part of the electronic expansion valve 330 and the refrigerant side flow plate 100 are bolted, and the coil part and the valve core part of the electronic expansion valve 330 are radially sealed by an X-ring.

[0105] It should be noted that the above bolt connection can also be replaced by a clamping connection.

[0106] However, it is not limited thereto. In other embodiments, the refrigerant side component 300 and the cooler 500 may also be welded to the refrigerant side flow channel plate 100 respectively, and the coolant side component 400 may be welded to the coolant side flow channel plate 200 .

[0107] In summary, the thermal management integrated module provided in the present application highly integrates the coolant side component 400 and the refrigerant side component 300, and reduces 1-2 sheet metal brackets per component on average for the coolant side component 400 fixed on the coolant side flow channel plate 200 and the refrigerant side component 300 fixed on the refrigerant side flow channel plate 100.

[0108] Each first flow channel 210 on the coolant side flow channel plate 200 and each second flow channel 120 on the refrigerant side flow channel plate 100 are equivalent to a pipeline in the traditional design. After the integrated arrangement, more than 10 brackets and more than 20 pipelines can be saved as a whole, which simplifies the cabin layout and greatly reduces the volume, weight and cost of the thermal management integrated module.

[0109] Furthermore, since the coolant side flow channel plate 200 and the refrigerant side flow channel plate 100 are equivalent to integrating more than 20 pipelines in the traditional design, the overall flow resistance of the coolant and the refrigerant can be reduced. Moreover, the circulation distance of the coolant and the refrigerant is greatly reduced, the heat loss in the flow is reduced, and the energy utilization efficiency is improved.

[0110] Moreover, after high integration, the production rhythm of the vehicle production line can be improved, the vehicle production efficiency can be improved, and the labor intensity of the employees in the vehicle assembly line can be reduced. The vehicle assembly plant only needs to manage one part number, which reduces management costs.
