DETAILED DESCRIPTION

[0061] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0062] With the continuous development of new energy vehicle technology, vehicle thermal management systems are becoming increasingly complex. These systems typically integrate several key components, including the cabin, battery, motor, and electronic control. Heat is exchanged through a refrigerant fluid, ultimately maintaining each functional area within the target temperature range.

[0063] However, switching between different pipelines during the operation of the thermal management system often uses valve combinations such as three-way valves or four-way valves, which requires the arrangement of a large number of valves, making the system pipeline design complex and requiring a large assembly space.

[0064] Based on the above technical problems, the present invention proposes an embodiment of the present invention. The embodiment of the present invention may include a first valve body 101, a second valve body 102, and a valve core 103. The second valve body 102 is connected to the first valve body 101. The end of the second valve body 102 away from the first valve body 101 is provided with an interface group 1021. The interface group 1021 includes at least fourteen interfaces, and the at least fourteen interfaces are spaced apart from each other on the second valve body 102. The valve core 103 is rotatably connected to the first valve body 101. The valve core 103 is provided with at least two groups of switching grooves 1031. When the valve core 103 is driven to rotate by an external force, the switching grooves 1031 are switched to contact the interface groups 1021 to switch the pipeline connection state corresponding to different interfaces. As a result, only one fourteen-way valve 1 is required to be arranged, and each load in the thermal management system can be directly connected to the fourteen-way valve 1 to meet the pipeline switching requirements, simplify the system pipeline design, and significantly reduce the required pipeline assembly space.

[0065] Reference Figure 1-7 An embodiment of the present invention provides a fourteen-way valve 1, which may include a first valve body 101, a second valve body 102 and a valve core 103, wherein the second valve body 102 is connected to the first valve body 101, wherein an interface group 1021 is provided at the end of the second valve body 102 away from the first valve body 101, and the interface group 1021 includes at least fourteen interfaces, and at least fourteen of the interfaces are separated from each other on the second valve body 102.

[0066] The valve core 103 is rotatably connected to the first valve body 101, and at least two groups of conversion grooves 1031 are provided on the valve core 103. When the valve core 103 is driven to rotate by external force, the conversion grooves 1031 are switched to form contact with the interface group 1021 to convert the pipeline connection status corresponding to different interfaces.

[0067] In an embodiment of the present invention, the first valve body 101, the second valve body 102 and the valve core 103, wherein the first valve body 101 and the second valve body 102 can be connected. For example, the first valve body 101 and the second valve body 102 can be an integrated structure. The end of the second valve body 102 away from the first valve body 101 is provided with an interface group 1021, and the interface group 1021 can include at least fourteen interfaces. Each interface is used to connect a pipeline, and the different interfaces in the second valve body 102 are separated from each other, that is, not connected to each other. Each interface of the interface group 1021 is connected to the first valve body 101 respectively. The valve core 103 is rotatably connected to the first valve body 101, and at least two groups of conversion grooves 1031 are provided on the valve core 103. When the valve core 103 rotates under the driving action of external force, the different conversion grooves 1031 on the valve core 103 respectively form contact with the interface group 1021, so that the pipeline connection state between different interfaces can be changed by the shape design of different conversion grooves 1031. In this way, the switching requirements of all pipelines in the thermal management system can be realized, the pipeline design of the thermal management system can be simplified, and the assembly space required for the pipeline can be greatly reduced.

[0068] An optional embodiment of the utility model, referring to Figure 2 As shown, the valve core 103 is a cylindrical structure and is clearance-matched with the first valve body 101 .

[0069] In an embodiment of the present invention, the valve core 103 may be a cylindrical structure, which can facilitate the rotation of the valve core 103 and enable the center of gravity of the valve core 103 to be on the central axis of the valve core 103, which can facilitate the external rotary motion output device to drive the valve core 103 to rotate and reduce the radial load of the rotary motion output device. In some embodiments, the rotary motion output device may include but is not limited to a servo motor, a stepper motor, etc. The valve core 103 and the first valve body 101 are clearance-fitted, which can improve the sealing between the valve core 103 and the first valve body 101, so that when the valve core 103 rotates to form contact with one set of conversion grooves 1031, there is no gap between the valve core 103 and the first valve body 101, thereby ensuring that the interface group 1021 and at least one other set of conversion grooves 1031 do not form a pipeline communication state.

[0070] An optional embodiment of the utility model, referring to Figure 4 、 Figure 5 as well as Figure 6As shown, at least two groups of conversion grooves 1031 are arranged on the side of the valve core 103 at equal angles around the center of the valve core 103, and the centers of two adjacent groups of conversion grooves 1031 form a first angle α with the valve core 103. Each time the valve core 103 rotates by the first angle, a group of conversion grooves 1031 switches to contact the interface group 1021.

[0071] In an embodiment of the present invention, when the valve core 103 is a cylinder, at least two groups of the conversion grooves 1031 are distributed at equal angles on the side of the valve core 103 around the center of the valve core 103. The number of groups of the conversion grooves is proportional to the number of operating modes of the thermal management system. For example, the more operating modes are set, the more pipelines need to be converted, and correspondingly, the more groups of conversion grooves 1031 are set. The first angle is associated with the number of groups of the conversion grooves 1031. For example, when the conversion grooves 1031 are set in two groups, the first angle can be 180°; for another example, when the conversion grooves 1031 are set in three groups, the first angle can be 120°; for another example, when the conversion grooves 1031 are set in four groups, the first angle can be 45°; for another example, when the conversion grooves 1031 are set in six groups, the first angle can be 60°, etc.

[0072] Therefore, each time the valve core 103 rotates the first angle, it can switch to another set of the conversion grooves 1031 to form contact with the interface group 1021, so that the pipeline connection status between the pipelines connected to different interfaces on the interface group 1021 can be adjusted through different designs on the conversion grooves 1031.

[0073] In some embodiments, each group of conversion grooves 1031 may include at least fourteen grooves, each of which corresponds to each interface, so that the communication status between different pipelines can be controlled through the communication between different grooves.

[0074] There are at least two ways to achieve communication between different grooves:

[0075] First, a connecting hole is opened between two adjacent grooves to achieve communication between the two grooves;

[0076] Second, the two adjacent grooves are made into an integrated structure. That is, when processing the valve core 103, the two grooves are processed as a whole, and a single groove is machined so that the groove covers the two interfaces corresponding to the two grooves. As a result, the groove designs corresponding to different groups of conversion grooves 1031 are different, and the mutual contact and cooperation between different groups of conversion grooves 1031 and the interface group 1021 can realize the switching of different operating modes of the thermal management system.

[0077] An optional embodiment of the utility model, referring to Figure 1 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, along the radial direction of the valve core 103 , the width of the second valve body 102 gradually increases from the end close to the first valve body 101 to the end far away from the first valve body 101 .

[0078] In an embodiment of the present invention, along the radial direction of the valve core 103, the width W1 of the second valve body 102 gradually increases from the end close to the first valve body 101 to the end away from the first valve body 101. As a result, the opening space of the interface group 1021 located on the end of the second valve body 102 away from the first valve body 101 is larger, and a larger assembly space can be reserved for each interface. On the one hand, it can facilitate the connection between the pipeline and the interface and increase the flow rate entering the interface. On the other hand, the width of the second valve body 102 becomes smaller as it is closer to the end of the first valve body 101, so that it is convenient to set a smaller first angle. Therefore, it can be applied to thermal management systems with more operating mode switching scenarios. On the basis of meeting the more complex pipeline switching scenarios, it can also simplify the pipeline design of the system and greatly reduce the assembly space required for the pipeline.

[0079] An optional embodiment of the utility model, referring to Figure 1 and Figure 7 As shown, the cross-sectional shape of the second valve body 102 along the axial direction of the valve core 103 is rectangular, and the interface groups 1021 are distributed in an array on the second valve body 102 .

[0080] In this embodiment of the utility model, considering the ease of machining the conversion groove 1031 and the neatness of the pipeline arrangement, the cross-section of the second valve body 102 along the axial direction of the valve core 103 is rectangular. The interface groups 1021 are arranged in an array on the second valve body 102. The term "array" can be understood as being evenly arranged in multiple rows and columns. In some embodiments, the at least fourteen interfaces on the interface group 1021 can be arranged in four rows and five columns. For example, the interface group 1021 includes at least a first interface 102101, a second interface 102102, a third interface 102103, a fourth interface 102104, a fifth interface 102105, a sixth interface 102106, a seventh interface 102107, an eighth interface 102108, a ninth interface 102109, a tenth interface 102110, an eleventh interface 102111, a twelfth interface 102112, a thirteenth interface 102113, and a fourteenth interface 102114. The distribution is as follows Figure 7 As shown, some areas can be set as blind ends (i.e., no interfaces are provided). In the case of a blind end, a corresponding area on the valve core 103 should also be provided with a groove, so as to facilitate the connection of the interfaces located on the four sides of the blind end. For example, the second row of the second valve body 102 is set as a blind end. The second row of the valve core 103 is also provided with a groove, connecting some interfaces of the first and third rows. Those skilled in the art can also determine the specific number of interfaces to be provided based on actual pipeline requirements, and no excessive restrictions are imposed here.

[0081] An optional embodiment of the utility model, referring to Figure 1 、 Figure 2 as well as Figure 3 As shown, a driving shaft 1032 is provided at the center of one end surface of the valve core 103 . The driving shaft 1032 passes through the first valve body 101 and extends to the outside of the first valve body 101 .

[0082] In this embodiment of the present invention, a drive shaft 1032 is provided at the center of one end surface of the valve core 103. The drive shaft 1032 passes through the first valve body 101 and extends outside the first valve body 101. The drive shaft 1032 is coaxially fixed to the output shaft of an external rotational motion output device, so that when the output shaft of the rotational motion output device rotates, the valve core 103 is driven to rotate synchronously.

[0083] The valve core 103 is rotatably connected to the first valve body 101 and may be a bearing or other device, which is not limited here.

[0084] Reference Figure 8-20As shown, an embodiment of the present invention further provides a heat pump air conditioner, which may include the fourteen-way valve 1 as described in any one embodiment of the utility model, and the heat pump air conditioner also includes an evaporator 7, a condenser 2, a first heat exchanger 3, a second heat exchanger 4, a third heat exchanger 8, an electrically controlled heat exchange device 6 and a battery heat exchange device 5, the inlet and outlet of the evaporator 7 are respectively connected to the interface group 1021, the inlet and outlet of the condenser 2 are respectively connected to the interface group 1021, the inlet and outlet of the first heat exchanger 3, the inlet and outlet of the second heat exchanger 4, and the inlet and outlet of the third heat exchanger 8 are respectively connected to the interface group 1021, wherein the first heat exchanger 3 and the second heat exchanger 4 are located inside the vehicle, and the third heat exchanger 8 is located outside the vehicle. The liquid inlet and outlet of the electrically controlled heat exchange device 6 are respectively connected to the interface group 1021, and the liquid inlet and outlet of the battery heat exchange device 5 are respectively connected to the interface group 1021. When the valve core 103 is driven to rotate by external force, the conversion groove 1031 is switched to form contact with the interface group 1021 to convert the operating mode of the heat pump air conditioner.

[0085] In an embodiment of the present invention, all loads in the thermal management system can be directly connected to the interface group 1021 of the fourteen-way valve 1 without adding other valves in the middle, thereby reducing the number of valves in the heat pump air conditioner and the complexity of the pipeline. On the basis of reducing the assembly space, it can also greatly reduce the difficulty of maintenance.

[0087] In an embodiment of the present invention, the heat pump air conditioner may further include components such as a throttle valve 10 and a compressor 9. When the air conditioner is operating, the compressor 9 compresses the low-temperature, low-pressure refrigerant gas generated by the evaporator 7 and discharges the high-pressure refrigerant gas into the condenser 2. The condenser 2 uses water to perform heat exchange (heat release process) with the high-pressure refrigerant gas to form a liquid refrigerant, which is then sent to the throttle valve 10 for cooling and pressure reduction before being sent to the evaporator 7. It absorbs heat in the evaporator 7 and vaporizes. As a result, the water flowing out of the evaporator 7 is low-temperature cooling water, and the water flowing out of the condenser 2 is high-temperature cooling water.

[0088] The battery heat exchanger 5 is used to exchange heat with the vehicle's batteries. It can be a cooling plate or cooling tube with cooling channels, and it contacts the batteries to achieve heat exchange. The electronically controlled heat exchanger 6 is used to exchange heat with components such as the vehicle's control panel and motor. Similar to the battery heat exchanger 5, it can be a cooling plate or cooling tube with cooling channels, and it can be a cooling plate or cooling tube with cooling channels.

[0089] The first heat exchanger 3, the second heat exchanger 4, and the third heat exchanger 8 are respectively related devices for heat exchange between air and cooling water, so that the temperature inside the vehicle can be regulated by heat exchange between the air inside the vehicle and the first heat exchanger 3 or the second heat exchanger 4.

[0090] For another example, the temperature of the cooling water is adjusted by heat exchange between the outside air and the third heat exchanger 8. In some embodiments, a water tank 11 may be provided between the liquid outlet of the third heat exchanger 8 and the interface group 1021 for storing the cooling water after heat exchange.

[0091] In the embodiment of the present invention, in order to provide the flow power of the cooling water, a device such as a water pump 12 may be added to the corresponding pipeline. For example, a water pump 12 may be installed between the liquid outlet of the evaporator 7 and the interface group 1021, and / or a water pump 12 may be installed between the liquid inlet of the condenser 2 and the interface group 1021. Here, there are no restrictions on the installation position of the water pump 12.

[0092] In an optional embodiment of the utility model, referring to Figure 9 and Figure 10 As shown, when one group of the conversion grooves 1031 is in contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the second heat exchanger 4, the liquid outlet of the second heat exchanger 4 is connected to the liquid inlet of the battery heat exchange device 5, and the liquid outlet of the battery heat exchange device 5 is connected to the liquid inlet of the condenser 2.

[0093] The liquid outlet of the evaporator 7 is connected to the liquid inlet of the third heat exchanger 8, the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the electrically controlled heat exchange device 6, and the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the evaporator 7.

[0094] In the embodiment of the present invention, the above-mentioned operating mode can be regarded as the first operating mode of the heat pump air conditioner. The valve core 103 blocks the interface fluid path of the interface group 1021, and the different grooves conduct the interface, thereby achieving fluid communication between different interfaces. The high-temperature cooling water flows out of the condenser 2 and flows into the second heat exchanger 4. Then, it flows into the battery heat exchange device 5 through the second heat exchanger 4, and finally flows into the condenser 2 for circulation. It is used to provide heat to the second heat exchanger 4 and the battery heat exchange device 5, so that it can be suitable for preheating the battery when the external environment is at a low temperature, or for heating the battery and the vehicle cabin during the vehicle startup phase.

[0095] The low-temperature cooling water flows out of the evaporator 7 and into the third heat exchanger 8 located outside the vehicle. From the third heat exchanger 8, it flows to the electrically controlled heat exchange device 6, and finally from the electrically controlled heat exchange device 6 to the evaporator 7, where it circulates. The low-temperature cooling water generated by the evaporator 7 is further cooled by the third heat exchanger 8 located in the low-temperature environment outside the vehicle, thereby providing sufficient cooling capacity for the electrically controlled heat exchange device 6 to dissipate heat, thereby improving liquid cooling efficiency.

[0096] In some embodiments, when cabin heating is not required, the second heat exchanger 4 only passes high-temperature cooling water. When the blower is not turned on, the heat exchange effect between the second heat exchanger 4 and the air in the cabin can be ignored, so the cabin does not need to be heated.

[0097] In an optional embodiment of the utility model, referring to Figure 11 and Figure 12 As shown, when one group of the conversion grooves 1031 is in contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the second heat exchanger 4, and the liquid outlet of the second heat exchanger 4 is connected to the liquid inlet of the condenser 2.

[0098] The liquid outlet of the evaporator 7 is connected to the liquid inlet of the third heat exchanger 8, the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the electrically controlled heat exchange device 6, and the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the evaporator 7.

[0099] In the embodiment of the present invention, the above-described operating mode can be considered the second operating mode of the heat pump air conditioner. High-temperature cooling water flows from the condenser 2 to the second heat exchanger 4, then flows through the second heat exchanger 4 and circulates in the condenser 2. Thus, the condenser 2 provides heat to the second heat exchanger 4 located inside the vehicle. For example, this second operating mode is used when the vehicle cabin needs to be heated during winter parking.

[0100] Low-temperature cooling water flows from the evaporator 7 to the third heat exchanger 8 located outside the vehicle, then flows through the third heat exchanger 8 to the electrically controlled heat exchange device 6, and finally from the electrically controlled heat exchange device 6 to the evaporator 7, where it circulates. This allows the electrically controlled waste heat to be recovered and sent to the evaporator 7. When the vehicle's air intake grille is closed, the third heat exchanger 8 does not undergo forced convection heat exchange with the outside environment, allowing the vehicle cabin to be heated simultaneously by the third heat exchanger 8 and the second heat exchanger 4.

[0101] In an optional embodiment of the utility model, referring to Figure 13 and Figure 14As shown, when one group of the conversion grooves 1031 is in contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the electrically controlled heat exchange device 6, the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the third heat exchanger 8, and the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the condenser 2.

[0102] The liquid outlet of the evaporator 7 is connected to the liquid inlet of the first heat exchanger 3 , the liquid outlet of the first heat exchanger 3 is connected to the liquid inlet of the battery heat exchange device 5 , and the liquid outlet of the battery heat exchange device 5 is connected to the liquid inlet of the evaporator 7 .

[0103] In the embodiment of the present invention, the above-described operating mode can be considered the third operating mode of the heat pump air conditioner, wherein the high-temperature cooling water flows out of the condenser 2 and flows into the electrically controlled heat exchange device 6, then flows from the electrically controlled heat exchange device 6 to the third heat exchanger 8, and finally flows from the third heat exchanger 8 to the condenser 2 for circulation. In scenarios where the cabin, battery, electronic control, etc. need to be cooled during high temperatures in the summer or when the vehicle is traveling for long periods of time, the high-temperature cooling water can be used to cool components such as the motor and electronic control.

[0104] The low-temperature cooling water flows out of the evaporator 7 and into the first heat exchanger 3. From the first heat exchanger 3, it flows into the battery heat exchange device 5. Finally, from the battery heat exchange device 5, it flows back into the evaporator 7 for circulation. In this way, the low-temperature cooling water in the evaporator 7 can be used to cool the vehicle cabin and batteries.

[0105] In this operating mode, the evaporator 7 cools the vehicle cabin and the battery, and the third heat exchanger 8 cools the electronically controlled heat exchange device 6 .

[0106] In an optional embodiment of the utility model, referring to Figure 15 and Figure 16 As shown, when one group of the conversion grooves 1031 is in contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the second heat exchanger 4, and the liquid outlet of the second heat exchanger 4 is connected to the liquid inlet of the condenser 2.

[0107] The liquid outlet of the evaporator 7 is connected to the liquid inlet of the third heat exchanger 8, the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the electrically controlled heat exchange device 6, the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the battery heat exchange device 5, and the liquid outlet of the battery heat exchange device 5 is connected to the liquid inlet of the evaporator 7.

[0108] In the embodiment of the present invention, the above-mentioned operating mode can be regarded as the fourth operating mode of the heat pump air conditioner. Among them, high-temperature cooling water flows out of the condenser 2 and flows into the second heat exchanger 4, and then flows from the second heat exchanger 4 to the condenser 2 for circulation. Low-temperature cooling water flows out of the evaporator 7 and flows into the electric-controlled heat exchange device 6, and then flows from the electric-controlled heat exchange device 6 to the battery heat exchange device 5, and finally flows to the evaporator 7 for circulation. For example, when the vehicle is parked for a rest in a low-temperature outdoor environment (such as an outdoor temperature below 15°C), the excess heat from the battery and / or electronic control can be recovered to heat the cabin. Therefore, the low-temperature cooling water can be heated by the battery heat exchange device 5 and the electric-controlled heat exchange device 6. Increasing the temperature of the low-temperature cooling water can improve the heat exchange efficiency of the evaporator 7. This can improve the operating efficiency of the system and achieve the purpose of heat recovery.

[0109] Alternatively, in this operating mode, while the vehicle is driving or the battery is charging, ambient temperature is used to dissipate heat. The air conditioning system is not operating, and the electronic control and battery can be cooled by ambient temperature without the air conditioning system being turned on. The high-temperature cooling water can be stopped from circulating, while the low-temperature cooling water continues to circulate via the water pump 12, and the evaporator 7 is not operating. This allows heat to be dissipated by utilizing the temperature difference between the ambient temperature and the cooling water in the battery and electronic control.

[0110] In an optional embodiment of the utility model, referring to Figure 17 and Figure 18 As shown, when one group of the conversion grooves 1031 is in contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the electrically controlled heat exchange device 6, the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the third heat exchanger 8, and the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the condenser 2.

[0111] The liquid outlet of the evaporator 7 is communicated with the liquid inlet of the first heat exchanger 3 , and the liquid outlet of the first heat exchanger 3 is communicated with the liquid inlet of the evaporator 7 .

[0112] In the embodiment of the present invention, the above-mentioned operating mode can be regarded as the fifth operating mode of the heat pump air conditioner. High-temperature cooling water flows out of the condenser 2 and flows to the electrically controlled heat exchange device 6, then flows from the electrically controlled heat exchange device 6 to the third heat exchanger 8, and finally flows from the third heat exchanger 8 to the condenser 2 for circulation. Low-temperature cooling water flows out of the evaporator 7 and flows to the first heat exchanger 3, then flows from the first heat exchanger 3 to the evaporator 7 for circulation.

[0113] This operating mode can be activated when the vehicle cabin and electronic control need to be cooled while the vehicle is driving or when parked for a rest. The high-temperature cooling water from the condenser 2 flows through the electronic control heat exchange device 6 to cool the electronic control, and then cools the vehicle cabin through the combination of the third heat exchanger 8 and the first heat exchanger 3.

[0114] In an optional embodiment of the utility model, referring to Figure 19 and Figure 20 As shown, when one group of the conversion grooves 1031 forms contact with the interface group 1021, the liquid outlet of the condenser 2 is connected to the liquid inlet of the second heat exchanger 4, the liquid outlet of the second heat exchanger 4 is connected to the liquid inlet of the electrically controlled heat exchange device 6, the liquid outlet of the electrically controlled heat exchange device 6 is connected to the liquid inlet of the third heat exchanger 8, and the liquid outlet of the third heat exchanger 8 is connected to the liquid inlet of the condenser 2.

[0115] The liquid outlet of the evaporator 7 is connected to the liquid inlet of the first heat exchanger 3 , the liquid outlet of the first heat exchanger 3 is connected to the liquid inlet of the battery heat exchange device 5 , and the liquid outlet of the battery heat exchange device 5 is connected to the liquid inlet of the evaporator 7 .

[0116] In this embodiment of the present invention, the above-described operating mode can be considered the sixth operating mode of the heat pump air conditioner. High-temperature cooling water flows from the condenser 2 to the second heat exchanger 4. It then flows from the second heat exchanger 4 to the electrically controlled heat exchange device 6, and finally from the electrically controlled heat exchange device 6 to the third heat exchanger 8, where it circulates through the condenser 2. Low-temperature cooling water flows from the evaporator 7 to the first heat exchanger 3, then from the first heat exchanger 3 to the battery heat exchange device 5, and finally to the evaporator 7, where it circulates. This operating mode is suitable for scenarios where high ambient humidity requires cabin dehumidification. The second heat exchanger 4 cools the electrically controlled heat exchange device 6. The third heat exchanger 8 lowers the temperature of the high-temperature cooling water, recovers battery waste heat through the battery heat exchange device 5, and raises the temperature of the low-temperature cooling water. This improves the evaporation efficiency of the evaporator 7 and the condensation efficiency of the condenser 2, thereby comprehensively enhancing the dehumidification efficiency of the air conditioner.

[0117] For example, in one embodiment, the heat pump air conditioner can switch between the six operating modes described above. In this case, the first angle is set to 60°. Thus, the valve core 103 can be controlled to rotate N*60° each time. For example, N is an integer greater than or equal to 1 and less than 6.

[0118] The present invention also discloses a vehicle, which may include the heat pump air conditioner described in any one of the above-mentioned embodiments of the present invention. The first heat exchanger 3, the second heat exchanger 4, and the third heat exchanger 8 may all be installed in the vehicle cabin, wherein the third heat exchanger 8 may be connected to the external environment via a grille.

[0119] In summary, the present invention discloses a fourteen-way valve 1, a heat pump air conditioner, and a vehicle. The present invention may include a first valve body 101, a second valve body 102, and a valve core 103. The second valve body 102 is connected to the first valve body 101. The end of the second valve body 102, away from the first valve body 101, is provided with a port group 1021. The port group 1021 includes at least fourteen ports, which are spaced apart from each other on the second valve body 102. The valve core 103 is rotatably connected to the first valve body 101. Furthermore, the valve core 103 is provided with at least two groups of switching grooves 1031. When the valve core 103 is driven to rotate by an external force, the switching grooves 1031 are switched to contact the port groups 1021 to switch the pipeline connection state corresponding to the different ports. Thus, only one fourteen-way valve 1 is required to connect each load in the thermal management system directly to the fourteen-way valve 1, thereby meeting pipeline switching requirements, simplifying the system's pipeline design, and significantly reducing the required assembly space for the pipelines.
