In order to meet the thermal management requirements of components such as motors, batteries, and passenger compartments, the thermal management system usually includes a refrigerant flow path and a coolant flow path to ensure high heat exchange efficiency. The refrigerant flow path usually includes many components such as a single-suction single-row compressor, a solenoid valve, an electronic expansion valve, and multiple heat exchangers, resulting in a complex structure of the thermal management system and high cost. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a refrigerant flow path integrated seat, a thermal management system and a vehicle, which can improve the heat exchange efficiency of the thermal management system, simplify the structure of the thermal management system and reduce production costs.

[0005] The refrigerant flow path integrated seat provided in the embodiment of the present application includes a compressor connection part, a solenoid valve connection part, an electronic expansion valve connection part and a plurality of heat exchanger connection parts. The compressor connection part can be connected to the compressor of the refrigerant flow path system. The solenoid valve connection part can be connected to the solenoid valve of the refrigerant flow path. The electronic expansion valve connection part can be connected to the electronic expansion valve of the refrigerant flow path.

[0081] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0082] The thermal management system of new energy vehicles (such as pure electric vehicles) usually includes a coolant flow system and a refrigerant flow system.

[0083] The refrigerant flow system includes a single-suction single-row compressor, a passenger compartment evaporator, a passenger compartment condenser, an expansion valve, an off-board evaporator (chiller), an off-board condenser and other structures. The components are numerous and complicated, resulting in a relatively complex structure of the thermal management system and a high cost.

[0084] The coolant flow path system usually includes a water pump, a kettle, a motor heat exchange flow path, a battery heat exchange flow path, an external radiator, an external evaporator (chiller), etc. It can be seen that the external evaporator is involved in both the flow of refrigerant and the flow of coolant, and both refrigerant and coolant pass through the inside. The heat exchange between the refrigerant and the coolant is realized to realize the heat exchange between the refrigerant flow path and the coolant flow path, so as to utilize the refrigerant flow path to cool the electrical components (such as batteries and motors) outside the passenger compartment, and to realize the waste heat recovery of the electrical components outside the passenger compartment.

[0085] Similar to the cooling and heating air conditioner, the functions of the evaporator and condenser of the air conditioner can be interchanged through the refrigerant reversal. Similarly, the functions of the off-board evaporator and off-board condenser can also be interchanged, that is, the off-board evaporator can also be used as a condenser, and the off-board condenser can be used as an evaporator. When the off-board evaporator is connected in series in the battery thermal management flow path, the off-board evaporator can be used to cool the battery as well as to heat the battery.

[0086] Among them, the outboard condenser can be a liquid cooled condenser (LCC), that is, the refrigerant is condensed by heat exchange with the liquid. Therefore, this form of outboard condenser (liquid cooled condenser) also needs to participate in the coolant flow path like the outboard evaporator (chiller). Since the use of refrigerant to heat the electrical components outside the passenger compartment (such as batteries and motors) also requires the heat exchange between the refrigerant and the coolant in the outboard condenser, and then the coolant flows to the components to be heated, this system can be called a semi-indirect system.

[0087] Alternatively, the offboard condenser can also be an air-cooled condenser (same as the passenger compartment condenser, condensation is achieved through heat exchange between the refrigerant and the surrounding gas). This form of offboard condenser does not need to participate in the coolant flow path like the offboard evaporator (chiller), and can directly blow heat to the components to be heated (such as batteries) to directly heat the components to be heated, so this system can be called a direct system. Compared with the semi-indirect system, the heat pump efficiency of the direct system is high.

[0088] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a refrigerant flow path integrated seat 300 for a thermal management system. The refrigerant flow path integrated seat 300 includes: a compressor connection part, a solenoid valve connection part, an electronic expansion valve connection part and a heat exchanger connection part.

[0089] Among them, the compressor connection part is provided with a first exhaust interface, a second exhaust interface and an air intake interface, and the first exhaust interface, the second exhaust interface and the air intake interface are configured to be connected to the first exhaust port 711, the second exhaust port 712 and the air intake port 713 of the compressor respectively.

[0090] The refrigerant flow path integrated seat 300 provided in the embodiment of the present application includes a compressor connection part, a solenoid valve connection part, an electronic expansion valve connection part and a plurality of heat exchanger connection parts. The compressor connection part can be connected to the compressor of the refrigerant flow path system. The solenoid valve connection part can be connected to the solenoid valve of the refrigerant flow path. The electronic expansion valve connection part can be connected to the electronic expansion valve of the refrigerant flow path. The heat exchanger connection part can be connected to the heat exchanger of the refrigerant flow path.

[0091] Therefore, the refrigerant flow path integrated seat 300 of the present solution can realize the integrated installation of the compressor, solenoid valve, electronic expansion valve and heat exchanger of the thermal management system, which is beneficial to simplify the structure of the thermal management system and reduce production costs.

[0092] Furthermore, since the compressor connection portion is provided with a first exhaust interface, a second exhaust interface and an air intake interface, and the first exhaust interface is used to communicate with the first exhaust port 711 of the compressor, the second exhaust interface is used to communicate with the second exhaust port 712 of the compressor, and the air intake interface is used to communicate with the air intake port 713 of the compressor. Therefore, the refrigerant flow path integrated seat 300 provided in the embodiment of the present application uses a thermal management system that adopts a compressor with one air intake port 713 and two exhaust ports, that is, a single-suction double-row compressor. Compared with a single-suction single-row compressor, a single-suction double-row compressor has a higher heat exchange efficiency, which is beneficial to improving the heat exchange efficiency of the thermal management system.

[0093] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the compressor connection part includes an intake pipe joint 613, a first exhaust pipe joint 611, and a second exhaust pipe joint 612. The intake pipe joint 613 is provided with an intake interface, the first exhaust pipe joint 611 is provided with a first exhaust interface, and the second exhaust pipe joint 612 is provided with a second exhaust interface. The exhaust pressure of the first exhaust port 711 is lower than the exhaust pressure of the second exhaust port 712. The intake pipe joint 613, the first exhaust pipe joint 611, and the second exhaust pipe joint 612 are arranged in sequence in a straight line roughly along the first direction. Figure 1 , the first direction is from the upper left to the lower right.

[0094] In this solution, the compressor connection part includes an intake pipe joint 613, a first exhaust pipe joint 611, and a second exhaust pipe joint 612. One end of the intake pipe joint 613 is closed, and the other end is open, and the open end of the intake pipe joint 613 forms an intake interface. One end of the first exhaust pipe joint 611 is closed, and the other end is open, and the open end of the first exhaust pipe joint 611 forms a first exhaust interface. One end of the second exhaust pipe joint 612 is closed, and the other end is open, and the open end of the second exhaust pipe joint 612 forms a second exhaust interface.

[0095] Since the exhaust pressure of the first exhaust port 711 is less than the exhaust pressure of the second exhaust port 712, the first exhaust port 711 is the low-pressure exhaust port of the single-suction double-row compressor, and the second exhaust port 712 is the high-pressure exhaust port of the single-suction double-row compressor. The intake pipe joint 613, the first exhaust pipe joint 611 and the second exhaust pipe joint 612 are arranged in a straight line, and the first exhaust pipe joint 611 is located between the intake pipe joint 613 and the second exhaust pipe joint 612, which is consistent with the arrangement order of the intake port 713 and the two exhaust ports of the single-suction double-row compressor, thereby facilitating the docking between the compressor connection part and the single-suction double-row compressor.

[0096] It is understandable that, since pipe joints are generally cylindrical, the arrangement direction of the intake pipe joint 613, the first exhaust pipe joint 611, and the second exhaust pipe joint 612 can be the arrangement direction of the central axes of the three. When the intake pipe joint 613, the first exhaust pipe joint 611, and the second exhaust pipe joint 612 are arranged in sequence in a straight line approximately along the first direction, the central axis of the intake pipe joint 613, the central axis of the first exhaust pipe joint 611, and the central axis of the second exhaust pipe joint 612 are approximately on the same plane.

[0097] The term “arranged in sequence in a straight line substantially along the first direction” means that the arrangement may be a straight line in a strict sense, or may not be a straight line in a strict sense, but may be close to a straight line.

[0098] In an exemplary embodiment, there are multiple heat exchanger connection parts, which are divided into two groups. The first group of heat exchanger connection parts (i.e., the first in-vehicle heat exchanger connection part and the second in-vehicle heat exchanger connection part described below) is configured to connect the in-vehicle heat exchanger, and the second group of heat exchanger connection parts (i.e., the first out-vehicle heat exchanger connection part and the second out-vehicle heat exchanger connection part described below) is configured to connect the out-vehicle heat exchanger.

[0099] The first group of heat exchanger connections is located on one side of the second direction of the compressor connection, and the second group of heat exchanger connections is located on the other side of the second direction of the compressor connection, and the second direction is perpendicular to the first direction. Figure 1 , the second direction is from the lower left to the upper right.

[0100] If the number of heat exchanger connection parts is multiple and divided into two groups, then the number of heat exchangers in the refrigerant flow system is also multiple and divided into two groups. The first group is the in-vehicle heat exchanger, which can also be called the cabin heat exchanger, which mainly exchanges heat with the passenger compartment and is used for cooling and / or heating the passenger compartment. The second group is the out-vehicle heat exchanger, which can also be called the out-cabin heat exchanger, which mainly exchanges heat with components outside the passenger compartment (such as batteries, motors, etc.) and the outside environment.

[0101] The first group of heat exchanger connections and the second group of heat exchanger connections are respectively arranged on both sides of the second direction of the compressor connection, so that the first exhaust pipe joint 611 and the second exhaust pipe joint 612 of the compressor connection can be connected to both the first group of heat exchanger connections and the second group of heat exchanger connections, and the connections between the compressor connection and the heat exchanger connections on both sides do not affect each other, which is conducive to shortening the flow path length between the compressor connection and the first group of heat exchanger connections and the flow path length between the compressor connection and the second group of heat exchanger connections, thereby facilitating the miniaturization of the refrigerant flow path integrated seat 300 and the compactness of the refrigerant flow path system of the thermal management system.

[0102] Moreover, this arrangement allows the refrigerant discharged from the compressor to enter both the heat exchanger inside the vehicle and the heat exchanger outside the vehicle, which is conducive to combining more refrigerant circuits and realizing more thermal management modes.

[0103] In addition, such an arrangement makes the positions of the first group of heat exchanger connection parts relatively concentrated, and the positions of the second group of heat exchanger connection parts relatively concentrated, which is beneficial to simplifying the flow path layout of the refrigerant flow path integrated seat 300.

[0104] In an exemplary embodiment, the number of the solenoid valve connecting parts is multiple, and the multiple solenoid valve connecting parts are divided into two groups.

[0105] Among them, Figure 1 and Figure 2 As shown, the first group of solenoid valve connections are located between the compressor connection and the first group of heat exchanger connections, and are connected to the compressor connection and the first group of heat exchanger connections. The second group of solenoid valve connections are located between the compressor connection and the second group of heat exchanger connections, and are connected to the compressor connection and the second group of heat exchanger connections.

[0106] In this solution, the number of solenoid valve connection parts is multiple and divided into two groups, and the number of solenoid valves in the refrigerant flow system is also multiple and divided into two groups. Among them, the first group of solenoid valve connection parts is located between the compressor connection part and the first group of heat exchanger connection parts, and the first group of solenoid valve connection parts are connected to the compressor connection part and the first group of heat exchanger connection parts. The second group of solenoid valve connection parts is located between the compressor connection part and the second group of heat exchanger connection parts, and the second group of solenoid valve connection parts are connected to the compressor connection part and the second group of heat exchanger connection parts.

[0107] Such a layout is conducive to shortening the flow path length between the first group of solenoid valve connections and the compressor connection, the flow path length between the first group of solenoid valve connections and the first group of heat exchanger connections, the flow path length between the second group of solenoid valve connections and the compressor connection, and the flow path length between the second group of solenoid valve connections and the second group of heat exchanger connections, thereby facilitating the miniaturization of the refrigerant flow path integrated seat 300 and the compactness of the refrigerant flow path system of the thermal management system.

[0108] After assembly, the first set of solenoid valves is located on the refrigerant flow path between the in-vehicle heat exchanger and the compressor, and is used to control the on-off between the in-vehicle heat exchanger and the compressor. The second set of solenoid valves is located on the refrigerant flow path between the out-vehicle heat exchanger and the compressor, and is used to control the on-off between the out-vehicle heat exchanger and the compressor. By controlling the on-off of the first set of solenoid valves and the second set of solenoid valves, the reversal of the refrigerant flow path system can be achieved, thereby achieving the switching of different thermal management modes.

[0109] In addition, such an arrangement makes the positions of the first group of solenoid valve connection parts relatively concentrated, and the positions of the second group of solenoid valve connection parts relatively concentrated, which is beneficial to simplifying the flow path layout of the refrigerant flow path integrated seat 300.

[0110] In an exemplary embodiment, the number of the electronic expansion valve connection parts is multiple, and the multiple electronic expansion valve connection parts are divided into two groups.

[0111] Among them, Figure 1 and Figure 2 As shown, the first group of electronic expansion valve connections is located on one side of the second direction of the compressor connection, and is located on the side where the first group of heat exchanger connections are located, and is connected to the first group of heat exchanger connections. The second group of electronic expansion valve connections is located on the other side of the second direction of the compressor connection, and is located on the side where the second group of heat exchanger connections are located, and is connected to the second group of heat exchanger connections.

[0112] In this solution, the number of electronic expansion valve connections is multiple and divided into two groups, and the number of electronic expansion valves in the refrigerant flow system is also multiple and divided into two groups. Among them, the first group of electronic expansion valve connections and the first group of heat exchanger connections are located on the same side of the compressor connection, and the first group of electronic expansion valve connections are connected to the first group of heat exchanger connections. The second group of electronic expansion valve connections and the second group of heat exchanger connections are located on the same side of the compressor connection, and the second group of electronic expansion valve connections are connected to the second group of heat exchanger connections.

[0113] Such a layout is conducive to shortening the flow path length between the first group of electronic expansion valve connections and the first group of heat exchanger connections, and the flow path length between the second group of electronic expansion valves and the second group of heat exchanger connections, thereby facilitating the miniaturization of the refrigerant flow path integrated seat 300, and also facilitating the compactness of the refrigerant flow path system of the thermal management system.

[0114] After assembly, the first set of electronic expansion valves is connected to the in-vehicle heat exchanger, and can throttle the refrigerant flowing into or out of the in-vehicle heat exchanger. The second set of electronic expansion valves is connected to the out-vehicle heat exchanger, and can throttle the refrigerant flowing into or out of the out-vehicle heat exchanger.

[0115] In addition, such an arrangement makes the positions of the first group of electronic expansion valve connection parts relatively concentrated, and the positions of the second group of electronic expansion valve connection parts relatively concentrated, which is beneficial to simplifying the flow path layout of the refrigerant flow path integrated seat 300.

[0117] In this solution, the refrigerant flow path integrated seat 300 further includes a gas-liquid separator connection portion, and the refrigerant flow path system further includes a gas-liquid separator 73. The gas-liquid separator 73 can improve the safety of the compressor and prevent the compressor from liquid hammering.

[0118] The separation inlet 651 is connected to the first set of electromagnetic valve connections, ensuring that the refrigerant flowing out of the in-vehicle heat exchanger can enter the gas-liquid separator 73 and flow back to the compressor after being processed by the gas-liquid separator 73. The separation inlet 651 is connected to the second set of electromagnetic valve connections, ensuring that the refrigerant flowing out of the out-vehicle heat exchanger can enter the gas-liquid separator 73 and flow back to the compressor after being processed by the gas-liquid separator 73.

The first out-vehicle heat exchanger 723 is a liquid-cooled heat exchanger, which can be a plate heat exchanger. During assembly, the two refrigerant ports of each heat exchanger can be connected to the two pipe joints of the corresponding heat exchanger connection part (they can be connected directly or indirectly through connecting pipelines).

[0142] In this way, after the assembly is completed, the first exhaust port 711 of the compressor is connected to the first refrigerant port of the first in-vehicle heat exchanger 721, and a first solenoid valve 741 for controlling the on-off of the flow path is provided on the refrigerant flow path between the two. The second exhaust port 712 of the compressor is connected to the first refrigerant port of the second in-vehicle heat exchanger 722, and a second solenoid valve 742 for controlling the on-off of the flow path is provided on the refrigerant flow path between the two. The first exhaust port 711 of the compressor is connected to the first refrigerant port of the second out-vehicle heat exchanger 724, and a third solenoid valve 743 for controlling the on-off of the flow path is provided on the refrigerant flow path between the two. The second exhaust port 712 of the compressor is connected to the first refrigerant port of the second out-vehicle heat exchanger 724, and a fourth solenoid valve 744 for controlling the on-off of the flow path is provided on the refrigerant flow path between the two. The first refrigerant port of the second out-vehicle heat exchanger 724 is connected to the inlet of the gas-liquid separator 73, and a fifth solenoid valve 745 for controlling the on-off of the flow path is provided on the refrigerant flow path between the two. The first refrigerant port of the first in-vehicle heat exchanger 721 and the first refrigerant port of the first out-vehicle heat exchanger 723 are connected to the inlet of the gas-liquid separator 73, and a sixth solenoid valve 746 for controlling the on-off of the flow path is provided on the refrigerant flow path between the first in-vehicle heat exchanger 721 and the first out-vehicle heat exchanger 723 and the inlet of the gas-liquid separator 73.

The second refrigerant port of the second in-vehicle heat exchanger 722 is connected to the second refrigerant port of the first out-vehicle heat exchanger 723, and a third electronic expansion valve 753 is provided on the flow path between the two.

[0143] In this way, Fig.12 As shown, when the first solenoid valve 741 is opened, the second solenoid valve 742 is opened, the third solenoid valve 743 is closed, the fourth solenoid valve 744 is closed, the fifth solenoid valve 745 is opened, the sixth solenoid valve 746 is closed, and the first electronic expansion valve 751 is closed, the refrigerant discharged from the first exhaust port 711 of the compressor flows back to the compressor through the first in-car heat exchanger 721, the second electronic expansion valve 752, the second out-car heat exchanger 724, and the gas-liquid separator 73; the refrigerant discharged from the second exhaust port 712 of the compressor flows back to the compressor through the second in-car heat exchanger 722, the third electronic expansion valve 753, the second out-car heat exchanger 724, and the gas-liquid separator 73. In this mode, the first in-car heat exchanger 721 and the second in-car heat exchanger 722 are both condensers that heat the passenger compartment; the second out-car heat exchanger 724 is an evaporator that absorbs heat from the external environment.

[0144] like Fig.13As shown, when the first solenoid valve 741 is closed, the second solenoid valve 742 is closed, the third solenoid valve 743 is opened, the fourth solenoid valve 744 is opened, the fifth solenoid valve 745 is closed, and the sixth solenoid valve 746 is opened, the refrigerant discharged from the first exhaust port 711 and the second exhaust port 712 of the compressor enters the second off-vehicle heat exchanger 724, and is divided into two paths after flowing out of the second off-vehicle heat exchanger 724, one path enters the first on-vehicle heat exchanger 721 through the second electronic expansion valve 752, and the other path enters the first off-vehicle heat exchanger 723 through the first electronic expansion valve 751. The refrigerant flowing out of the first on-vehicle heat exchanger 721 and the first off-vehicle heat exchanger 723 enters the gas-liquid separator 73 and finally flows back to the compressor. In this mode, the second off-vehicle heat exchanger 724 is a condenser that releases heat to the external environment; the first on-vehicle heat exchanger 721 is an evaporator that can cool the passenger compartment; the first off-vehicle heat exchanger 723 is also an evaporator that can cool the battery.

[0145] In an exemplary embodiment, Figure 1 As shown, the refrigerant flow path integrated seat 300 is further provided with a first installation space 671 for installing the gas-liquid separator 73, and the gas-liquid separator connection portion is located in the first installation space 671. The refrigerant flow path integrated seat 300 is further provided with a second installation space 672 for installing the first off-vehicle heat exchanger 723, and the first off-vehicle heat exchanger connection portion is located in the second installation space 672.

[0146] The refrigerant flow path integrated seat 300 is divided into a first area, a second area and a third area along a third direction. The third direction is inclined relative to the first direction and is consistent with the width direction of the first external heat exchanger 723 .

[0147] Among them, the first installation space 671 is located in the first area; the compressor connection part, the first group of heat exchanger connection parts, the first group of solenoid valve connection parts, the first group of electronic expansion valve connection parts, the second group of solenoid valve connection parts and the eighth pipe joint 6408 are located in the second area; the first electronic expansion valve connection part 631, the seventh pipe joint 6407 and the second installation space 672 are located in the third area.

[0148] The first installation space 671 is provided so that the gas-liquid separator 73 can be directly installed on the refrigerant flow path integrated seat 300 without being connected through other pipes. In this way, during the assembly process, the gas-liquid separator 73 and the refrigerant flow path integrated seat 300 can be modularly installed to form an integrated module, and then connected with other components.

[0149] The second installation space 672 is provided so that the first off-vehicle heat exchanger 723 can be directly installed on the refrigerant flow path integrated seat 300 without being connected through other pipes. In this way, during the assembly process, the first off-vehicle heat exchanger 723 and the refrigerant integrated seat can also be modularly installed to form an integrated module, and then connected with other components.

[0150] The refrigerant flow path integrated seat 300 includes three areas along the third direction. The first area is mainly used to install the gas-liquid separator 73, so the structure related to the gas-liquid separator 73 (the gas-liquid separator connection part and the first installation space 671) is located in the first area. The third area is mainly used to install the first off-vehicle heat exchanger 723, so the structure related to the first off-vehicle heat exchanger 723 (the first off-vehicle heat exchanger connection part, the second installation space 672) is located in the second area. All the solenoid valve connections, the first group of electronic expansion valve connections, the compressor connection part and the eighth pipe joint 6408 are located in the second area, and the layout is relatively concentrated, which is conducive to the miniaturization and compactness of the refrigerant flow path integrated seat 300. Since the height of the first off-vehicle heat exchanger 723 is generally less than the height of the gas-liquid separator 73, the first electronic expansion valve connection part 631 and the seventh pipe joint 6407 are also arranged in the third area, so that the longitudinal heights of the three areas can be roughly equivalent, so that the layout of the refrigerant flow path system after assembly is relatively balanced and compact.

[0151] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the four-way flow channel 6614 is connected to the branch of the sixth pipe joint 6406, and along the circumference of the refrigerant flow path integrated seat 300, it bypasses the sixth solenoid valve connection part 626, the separation inlet 651, the separation outlet 652, the fifth solenoid valve connection part 625, the eighth pipe joint 6408, and the fourth solenoid valve connection part 624 in sequence, and is connected to the sixth pipe joint 6406.

[0152] Since the sixth pipe joint 6406 is far away from the sixth solenoid valve 746, the branch of the fourth flow channel 6604 connecting the sixth pipe joint 6406 is connected to the sixth pipe joint 6406 in an outer surrounding form, which not only realizes the smooth connection between the four-way flow channel 6614 and the sixth pipe joint 6406, but also prevents the fourth flow channel 6604 from interfering with other flow channels or other structures of the refrigerant flow path integrated seat 300.

[0153] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the first three-way flow channel 6615 is connected to the branch of the seventh pipe joint 6407, bypasses the fifth pipe joint 6405 and the first electronic expansion valve connection part 631 in sequence along the circumference of the refrigerant flow path integrated seat 300, and is connected to the seventh pipe joint 6407.

[0154] Since the second electronic expansion valve 752 and the third electronic expansion valve 753 are far apart from the seventh pipe joint 6407, the branch of the first three-way channel 6615 connecting the seventh pipe joint 6407 is connected to the seventh pipe joint 6407 in an outer surrounding manner, which not only realizes the smooth connection between the first three-way channel 6615 and the seventh pipe joint 6407, but also prevents the first three-way channel 6615 from interfering with other channels or other structures of the refrigerant flow path integrated seat 300.

[0155] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the flow cross-sectional area of ​​the first three-way flow channel 6615, the flow cross-sectional area of ​​the fifth flow channel 6605, the flow cross-sectional area of ​​the sixth flow channel 6606, the flow cross-sectional area of ​​the seventh flow channel 6607, the flow cross-sectional area of ​​the thirteenth flow channel 6613 and the flow cross-sectional area of ​​the branch of the four-way flow channel 6614 connecting to the sixth solenoid valve connecting part 626 are larger than the flow cross-sectional areas of other flow channels.

[0156] In this way, the flow rates of the branches of the first three-way flow channel 6615, the fifth flow channel 6605, the sixth flow channel 6606, the seventh flow channel 6607, the thirteenth flow channel 6613, and the fourth flow channel 6604 connected to the sixth solenoid valve connecting part 626 are relatively large, which is beneficial to improving the heat exchange efficiency.

[0157] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the interface direction of the solenoid valve connection part, the interface direction of the compressor connection part, the interface direction of the electronic expansion valve connection part and the interface direction of the second group of heat exchanger connections are the same. The interface direction of the first group of heat exchanger connections is opposite to the interface direction of the second group of heat exchanger connections.

[0158] In this way, the solenoid valve, the compressor, the electronic expansion valve, and the second group of heat exchangers are installed on the same side of the refrigerant flow path integrated seat 300, while the first group of heat exchangers are installed on the other side of the refrigerant flow path integrated seat 300. In this way, the layout of the components on both sides of the refrigerant flow path integrated seat 300 can be made more reasonable, avoiding the mutual influence caused by concentrated arrangement on the same side and increasing the difficulty of layout.

[0159] In one example, if Figure 1 and Figure 2 As shown, the interface direction of the gas-liquid separator connection part is also the same as the interface direction of the second group of heat exchanger connection parts.

[0160] In an exemplary embodiment, the refrigerant flow path integrated seat 300 is further provided with reinforcing ribs (not shown in the figure).

[0161] The provision of reinforcing ribs can improve the strength of the refrigerant integration seat and reduce the risk of deformation or even breakage of the refrigerant integration seat.

[0162] Among them, the reinforcing rib is a physical connection structure. The two ends of the reinforcing rib are connected to the corresponding structure, which can strengthen and support the connected structure and ensure the stability of the structure on both sides. The position of the reinforcing rib can be between some flow channels (that is, some flow channels are connected by reinforcing ribs), between some pipe joints (that is, some pipe joints are connected by reinforcing ribs), or between the pipe joint and the flow channel (that is, the pipe joint and the flow channel are connected by reinforcing ribs).

[0163] For example, a reinforcing rib is provided between the sixth flow channel 6606 and the seventh flow channel 6607. A reinforcing rib is provided between the branch of the four-way flow channel 6614 connecting the sixth pipe joint 6406 and the sixth flow channel 6606. A reinforcing rib is provided between the fifth pipe joint 6405 and the sixth pipe joint 6406, a reinforcing rib is provided between the fifth pipe joint 6405 and the branch of the first three-way flow channel 6615 connecting the seventh pipe joint 6407, and a reinforcing rib is provided between the sixth pipe joint 6406 and the fourth solenoid valve connecting portion 624.

[0164] In addition, reinforcing ribs may also be provided between the flow channel / pipe joint and other structures of the first off-vehicle heat exchanger 723. For example, reinforcing ribs are provided between a pipe joint of the first off-vehicle heat exchanger 723 used to connect the coolant flow path and a branch of the first three-way flow channel 6615 connected to the seventh pipe joint 6407. Reinforcements are provided between another pipe joint of the first off-vehicle heat exchanger 723 used to connect the coolant flow path and the third electronic expansion valve connection part 633. Reinforcing ribs may also be provided between the two pipe joints of the first off-vehicle heat exchanger 723 used to connect the coolant flow path.

[0165] like Figures 7 to 11 As shown, the embodiment of the present application further provides a thermal management system, including: a refrigerant flow system. The refrigerant flow system includes: a compressor, a solenoid valve, an electronic expansion valve, a heat exchanger, and a refrigerant flow integrated seat 300 as in any one of the above embodiments, such as Figures 3 to 10 shown.

[0166] Among them, the compressor is provided with a first exhaust port 711, a second exhaust port 712 and an air intake port 713, the compressor is connected to the compressor connection part; the heat exchanger is connected to the heat exchanger connection part; the solenoid valve is connected to the solenoid valve connection part; the electronic expansion valve is connected to the electronic expansion valve connection part.

[0167] The thermal management system provided in the embodiment of the present application includes the refrigerant flow path integrated seat 300 of any one of the above embodiments, and thus has all the beneficial effects of any of the above embodiments, which will not be repeated here.

[0168] In an exemplary embodiment, Fig.11As shown, the thermal management system further includes: a cooling liquid flow path system. The cooling liquid flow path system includes a cooling liquid path integrated seat 200, such as Figure 7 and Fig.10 The cooling liquid channel integrated seat 200 and the refrigerant channel integrated seat 300 are arranged side by side along the thickness direction of the refrigerant channel integrated seat 300 .

[0169] The plurality of heat exchangers include a first in-vehicle heat exchanger 721, a second in-vehicle heat exchanger 722, a first out-vehicle heat exchanger 723, and a second out-vehicle heat exchanger 724. The cooling liquid circuit integrated seat 200 is provided with a ninth pipe joint (i.e., the out-vehicle evaporator inlet pipe joint 4251 described below) and a tenth pipe joint (i.e., the out-vehicle evaporator outlet pipe joint 4252 described below). The interfaces of the ninth pipe joint and the tenth pipe joint face the refrigerant circuit integrated seat 300, and are used to dock with the two cooling liquid ports of the first out-vehicle heat exchanger 723.

[0170] In this way, the refrigerant flow path integrated seat 300 and the cooling liquid flow path integrated seat 200 form a double-layer structure, which can be used for modular installation of the refrigerant flow path system and modular installation of the cooling liquid flow path system respectively, thereby realizing modular installation of the thermal management system, which is conducive to the miniaturization and compactness of the thermal management system.

[0171] The first off-vehicle heat exchanger 723 is a liquid-cooled heat exchanger, including two refrigerant ports and two coolant ports. The ninth pipe joint and the tenth pipe joint of the coolant integrated seat face the coolant flow path integrated seat 300, which is convenient for docking with the first off-vehicle heat exchanger 723 installed on the coolant flow path integrated seat 300, thereby achieving relative fixation between the coolant flow path integrated seat 300 and the coolant path integrated seat 200.

[0172] Among them, Fig.11 As shown, the first in-car heat exchanger 721 is an in-cabin evaporator, the second in-car heat exchanger 722 is an in-cabin condenser, the first out-car heat exchanger 723 is an out-cabin evaporator (chiller), and the second out-car heat exchanger 724 is an out-cabin condenser. The first in-car heat exchanger 721, the second in-car heat exchanger 722, and the second out-car heat exchanger 724 are all finned heat exchangers, which only participate in the refrigerant flow system. The first out-car heat exchanger 723 is a plate heat exchanger, which participates in both the refrigerant flow system and the coolant flow system.

[0173] In an exemplary embodiment, the cooling liquid circuit integrated seat 200 is provided with an avoidance gap 2002, such as Figure 8 The pipe joints of the first group of heat exchanger connection parts of the refrigerant flow path integrated seat 300 (ie, the first pipe joint 6401 , the second pipe joint 6402 , the third pipe joint 6403 and the fourth pipe joint 6404 ) are inserted into the avoidance gap 2002 .

[0174] In this way, the space on the side of the cooling liquid circuit integrated seat 200 away from the refrigerant flow circuit integrated seat 300 can be reasonably utilized to arrange the first in-vehicle heat exchanger 721 and the second in-vehicle heat exchanger 722, making the layout of the thermal management system more reasonable and compact.

[0175] In an exemplary embodiment, the cooling liquid circuit integrated seat 200 includes: a five-way valve connection part 44 , a motor thermal management flow path connection part 41 , a battery thermal management flow path connection part 42 and a radiator connection part 43 .

[0176] like Fig.44 and Fig.45 As shown, the five-way valve connection part 44 is provided with five transition grooves separated from each other, and the five transition grooves are arranged to be connected to the five channels of the five-way valve 100 in a one-to-one correspondence. The five-way valve 100 is a three-position five-way valve with three working modes. The motor thermal management flow path connection part 41 is provided with a first inlet 411 and a first outlet 412. The battery thermal management flow path connection part 42 is provided with a second inlet 421 and a second outlet 422. The radiator connection part 43 is provided with a third inlet 431 and a third outlet 432.

[0177] The first inlet 411 , the first outlet 412 , the second inlet 421 , the second outlet 422 , and the third outlet 432 are connected to the five transition grooves in a one-to-one correspondence, respectively, and the third inlet 431 is connected to the first outlet 412 .

[0178] The cooling liquid circuit integrated seat 200 provided in the embodiment of the present application includes a five-way valve connection part 44, a motor thermal management flow path connection part 41, a battery thermal management flow path connection part 42 and a radiator connection part 43. The five-way valve connection part 44 can be connected to a three-position five-way valve with three working modes. The motor thermal management flow path connection part 41 can be connected to the components of the motor thermal management flow path, the battery thermal management flow path connection part 42 can be connected to the components of the battery thermal management flow path, and the radiator connection part 43 can be connected to the radiator 57.

[0179] Since the five transition grooves of the five-way valve connecting part 44 can be connected one-to-one with the five channels of the five-way valve 100, the first inlet 411 and the first outlet 412 can be connected with two transition grooves respectively, the second inlet 421 and the second outlet 422 can be connected with the other two transition grooves respectively, the third outlet 432 can be connected with the remaining transition groove respectively, and the third inlet 431 can be connected with the first outlet 412.

[0180] Therefore, the coolant circuit integrated seat 200 of the present solution can realize the integrated installation of the five-way valve 100, the motor thermal management circuit, the battery thermal management circuit and the radiator 57, which is beneficial to simplify the structure of the thermal management system and reduce production costs.

[0181] Compared with installing multiple control valves to switch the working mode of the coolant flow path of the thermal management system, this solution can switch the coolant flow path of the thermal management system between three working modes by installing a five-way valve 100, which is helpful to simplify the structure and electrical control method of the thermal management system, thereby reducing production costs.

[0182] Moreover, compared with an integrated control valve, such as an eight-way valve, the five-way valve 100 has a simpler structure. With a roughly equivalent volume, the flow channel cross-sectional area of ​​the five-way valve 100 can be made larger, thereby reducing the running flow resistance. Moreover, the five-way valve 100 of this solution has three valve positions corresponding to three working modes, and there is no problem of shifting.

[0183] In addition, the eight-way valve is not suitable for the direct system, while the five-way valve 100 and the coolant circuit integrated seat 200 of the present application can be applied to the direct system, which is beneficial to reduce the number of control valves of the direct system and further simplify the structure of the thermal management system.

[0184] In one example, when the five-way valve 100 is in the first working mode, the first inlet 411 is connected to the second outlet 422 through the five-way valve 100, and the third outlet 432 is connected to the second inlet 421 through the five-way valve 100. Since the first outlet 412 is connected to the third inlet 431, the motor thermal management flow path, the radiator 57, and the battery thermal management flow path are connected end to end to form a closed loop, such as Fig.38 As shown, in this mode, the radiator 57 can be used to dissipate heat for both the battery and the motor.

[0185] When the five-way valve 100 is in the second working mode, the first outlet 412 is connected to the second inlet 421 through the five-way valve 100, and the second outlet 422 is connected to the first inlet 411 through the five-way valve 100, and the motor thermal management flow path and the battery thermal management flow path are connected end to end to form a closed loop. Fig.40 As shown, in this mode, the waste heat from the motor can be used to heat the battery.

[0186] When the five-way valve 100 is in the third working mode, the first inlet 411 is connected to the third outlet 432 through the five-way valve 100, and the second inlet 421 is connected to the second outlet 422 through the five-way valve 100. Since the first outlet 412 is connected to the third inlet 431, the motor thermal management flow path and the radiator 57 are connected in series to form a closed loop, and the battery thermal management flow path forms a closed loop alone. Fig.42 In this mode, the radiator 57 can be used to cool the motor, and the off-board evaporator 54 (chiller) can be used to cool the battery, that is, the motor and the battery are cooled separately.

The U-shaped opening of the U-shaped rib 4137 is connected to the first notch 4134. The thickness of the U-shaped rib 4137 is less than the side wall height of the circular base 4133.

[0203] In an exemplary embodiment, Fig.48 and Fig.52 As shown, the thermal management system also includes a kettle 58 (such as Fig.53 As shown) and a coolant heater 53. The kettle 58 is connected in series with the first water pump 51, and the coolant heater 53 is connected in series with the second water pump.

[0205] The top of the kettle 58 is provided with an exhaust port 581, and the kettle 58 is provided with a guide plate 582 for increasing the flow path between the kettle inlet 4151 and the exhaust port 581. Fig.55 shown.

[0206] In one example, a water level sensor 583 is also provided on the top of the kettle 58. Fig.52 As shown, it is used to detect the water level in the kettle 58.

[0207] In an exemplary embodiment, at least a portion of the guide plate 582 is configured as a porous plate, such as Fig.50 shown.

[0208] At least a portion of the guide plate 582 is set as a porous plate, so that the gas in the coolant can be discharged upward through the porous plate, which is also beneficial to improving the exhaust effect.

[0209] In one example, if Fig.50 , Fig.54 and Fig.55 As shown, the guide plate 582 includes a first sub-plate 5821, a second sub-plate 5822 and a third sub-plate 5823. One end of the first sub-plate 5821 is located in the inlet of the kettle 58, and the kettle pipe joint is separated into an inlet and an outlet. One end of the second sub-plate 5822 is connected to the other end of the first sub-plate 5821, and a first flow passage is formed between the other end of the second sub-plate 5822 and the first side wall 5841 of the kettle 58. The third sub-plate 5823 is located on the upper side of the second sub-plate 5822, and one end of the third sub-plate 5823 is connected to the first side wall 5841 of the kettle 58, and a second flow passage is formed between the other end of the third sub-plate 5823 and the second side wall 5842 of the kettle 58.

The third sub-plate 5823 is set as a porous plate. Of course, the second sub-plate 5822 can also be set as a porous plate.

[0210] In an exemplary embodiment, Fig.14 , Fig.15 , Fig.16 and Fig.35 As shown, the five-way valve 100 includes: a housing 1 and a valve core 2.

[0211] Among them, Fig.17As shown, the housing 1 is provided with a valve cavity 1111 and five channels communicating with the valve cavity 1111. The valve core 2 (as shown Fig.19 and Fig. 20 1) is at least partially disposed in the valve chamber 1111 and is arranged to be in a first position (as shown) relative to the housing 1. Fig.37 As shown), the second position (as Fig.39 As shown), the third position (as Figures 25 to 34 as well as Fig.41 The five-way valve 100 is used to rotate between the first working mode, the second working mode and the third working mode to control the communication relationship between the five channels.

[0212] The five-way valve 100 provided in the embodiment of the present application includes a housing 1 and a valve core 2. A valve cavity 1111 is provided in the housing 1 to provide space for the assembly and movement of the valve core 2. The housing 1 is also provided with five channels connected to the valve cavity 1111 for connection with relevant components of the thermal management system to switch the flow direction of the coolant flow path in the thermal management system. The valve core 2 is installed in the valve cavity 1111 and has three working positions, namely a first position, a second position and a third position. When the valve core 2 rotates to different working positions, the connection relationship between the five channels will change, thereby switching the working mode of the five-way valve 100, and then switching the working mode of the thermal management system.

[0213] In other words, the five-way valve 100 provided in the embodiment of the present application has three valve positions, and correspondingly has three working modes. When the valve core 2 is in the first position, the five-way valve 100 is in the first valve position, such as Fig.37 When the valve core 2 is in the second position, the five-way valve 100 is in the second valve position, as shown in FIG. Fig.39 When the valve core 2 is in the third position, the five-way valve 100 is in the third valve position, as shown in FIG. Fig.41 As shown, it works in the third working mode.

[0214] Compared with setting up multiple control valves to switch the working mode of the coolant flow path of the thermal management system, this solution can switch the coolant flow path of the thermal management system between three working modes by controlling a five-way valve 100, which is helpful to simplify the structure and electrical control method of the thermal management system, thereby reducing production costs.

[0215] Moreover, compared with an integrated control valve, such as an eight-way valve, the five-way valve 100 has a simpler structure. With a roughly equivalent volume, the flow channel cross-sectional area of ​​the five-way valve 100 can be made larger, thereby reducing the running flow resistance. Moreover, the five-way valve 100 of this solution has three valve positions corresponding to three working modes, and there is no problem of shifting.

[0216] In addition, the eight-way valve is not suitable for the direct system, while the five-way valve 100 of the present application can be applied to the direct system, which is beneficial to reduce the number of control valves of the direct system and further simplify the structure of the thermal management system.

[0217] The valve core 2 may be partially located in the valve cavity 1111, and the other part may protrude from the valve cavity 1111 to connect with the drive device. The valve core 2 may also be completely located in the valve cavity 1111, and a part of the drive device may be inserted into the valve cavity 1111 to drive the valve core 2 to rotate.

[0218] In an exemplary embodiment, Fig.15 , Fig.16 and Fig.29 As shown, the five channels are distributed in two rows along the axial direction of the valve core 2 and in three columns along the circumferential direction of the valve core 2. The valve core 2 is provided with two axial connecting grooves (i.e., the first connecting groove 281 and the second connecting groove 282 described below, as shown in FIG. Fig.30 and Fig.33 ) and two circumferential connecting grooves (i.e., the third connecting groove 283 and the fourth connecting groove 284 described below, as shown Fig. 20 and Fig. 27 As shown in FIG. 1 , the axial connecting groove is arranged along the axial direction of the valve core 2, and is used to conduct two channels in the same column. The circumferential connecting groove is arranged along the circumference of the valve core 2, and is used to conduct two adjacent channels in the same row.

[0219] In an exemplary embodiment, Fig.15 and Fig.16 As shown, the three columns of channels are respectively a first column of channels, a second column of channels and a third column of channels which are adjacently arranged along the circumference of the valve core 2 , and the first column of channels includes one channel.

[0220] Two circumferential communication grooves are adjacently arranged along the axial direction of the valve core 2 to form a first row of communication grooves, and two axial communication grooves are adjacently arranged along the circumference of the valve core 2 to form a second row of communication grooves and a third row of communication grooves.

[0221] The first row of connecting grooves and the second row of connecting grooves are adjacently arranged along the circumference of the valve core 2, and the arrangement direction of the first row of connecting grooves, the second row of connecting grooves and the third row of connecting grooves is the same as the arrangement direction of the first row of channels, the second row of channels and the third row of channels.

[0222] In an exemplary embodiment, Fig.15 and Fig.16As shown, the five channels are respectively recorded as the first channel 1121, the second channel 1122, the third channel 1123, the fourth channel 1124 and the fifth channel 1125. The first channel 1121, the second channel 1122 and the third channel 1123 are arranged side by side in sequence along the circumference of the valve core 2. The fourth channel 1124 and the fifth channel 1125 are arranged side by side along the circumference of the valve core 2, and the fourth channel 1124 and the second channel 1122 are arranged side by side along the axial direction of the valve core 2, and the fifth channel 1125 and the third channel 1123 are arranged side by side along the axial direction of the valve core 2. The two axial connecting grooves are respectively recorded as the first connecting groove 281 and the second connecting groove 282, and the two circumferential connecting grooves are respectively recorded as the third connecting groove 283 and the fourth connecting groove 284.

[0223] like Fig.37 As shown, when the valve core 2 is in the first position, the first communication groove 281 is connected with the second channel 1122 and the fourth channel 1124, the second communication groove 282 is connected with the third channel 1123 and the fifth channel 1125, and the third communication groove 283 is connected with the first channel 1121. Since the third communication groove 283 is only connected with the first channel 1121, it is equivalent to closing the first channel 1121; the fourth communication groove 284 is not connected with any of the five channels. This mode is the first working mode of the five-way valve 100.

[0224] like Fig.39 As shown, when the valve core 2 is in the second position, the third communication groove 283 is connected to the first channel 1121 and the second channel 1122, and the first communication groove 281 is connected to the third channel 1123 and the fifth channel 1125. The second communication groove 282 is not connected to any of the five channels; the fourth communication groove 284 is only connected to the fourth channel 1124, which is equivalent to closing the fourth channel 1124. This mode is the second working mode of the five-way valve 100.

[0225] like Fig.40 As shown, when the valve core 2 is in the third position, the third communication groove 283 is connected to the second channel 1122 and the third channel 1123, and the fourth communication groove 284 is connected to the fourth channel 1124 and the fifth channel 1125. The first communication groove 281 is not connected to any of the five channels, and the second communication groove 282 is not connected to any of the five channels. This mode is the third working mode of the five-way valve 100.

[0226] In this way, the five-way valve 100 has three different working modes. Each time the valve core 2 rotates one gear, one working mode is switched. The coolant flow path of the thermal management system can also have three different working modes, and the flow direction of the liquid in the three working modes can be switched by controlling the five-way valve 100.

[0227] In an exemplary embodiment, Fig.19 , Fig. 20 , Fig.31 and Fig.34 As shown, the valve core 2 includes: a transverse partition 25, a first vertical partition 21, a first vertical partition 22, a third vertical partition 23 and a third vertical partition 24.

[0228] The transverse partition 25 is arranged along the circumferential direction of the valve core 2. The first vertical partition 21, the first vertical partition 22, the third vertical partition 23 and the third vertical partition 24 are all arranged along the axial direction of the valve core 2, and the first vertical partition 21, the first vertical partition 22, the third vertical partition 23 and the third vertical partition 24 are arranged in sequence along the circumferential direction of the valve core 2.

[0229] An axial communication groove is formed between the first vertical partition 22 and the first vertical partition 21. Another axial communication groove is formed between the third vertical partition 23 and the first vertical partition 22. The transverse partition 25 is located between the first vertical partition 21 and the third vertical partition 23, and is vertically connected to the first vertical partition 21, the first vertical partition 22, the third vertical partition 23 and the third vertical partition 24. In addition, the transverse partition 25 divides the space between the first vertical partition 21 and the third vertical partition 24 into two circumferential communication grooves.

[0230] In an exemplary embodiment, Fig.19 and Fig. 20 As shown, the valve core 2 further includes a first end plate 26 and a second end plate 27. The first end plate 26 and the second end plate 27 are both arranged opposite to the transverse partition 25 and are located on both sides of the transverse partition 25. In addition, the first end plate 26 and the second end plate 27 are both fixedly connected to the end of the first vertical partition 21, the end of the first vertical partition 22, the end of the third vertical partition 23, and the end of the third vertical partition 24.

Five channels are provided in the protruding portion 112, and the side wall of the cylindrical portion 111 is provided with openings connected to the five channels one by one.

[0239] In an exemplary embodiment, Fig.36As shown, the channels connecting the outlet end (i.e., the first outlet 412) and the inlet end (i.e., the first inlet 411) of the motor thermal management flow path are respectively recorded as the first channel 1121 and the fifth channel 1125, the channels connecting the inlet end (i.e., the second inlet 421) and the outlet end (i.e., the second outlet 422) of the battery thermal management flow path are respectively recorded as the second channel 1122 and the third channel 1123, and the channel connecting the outlet end (i.e., the third outlet 432) of the radiator 57 is recorded as the fourth channel 1124.
