DETAILED DESCRIPTION

[0061] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the 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 set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0062] With the continuous development of new energy vehicle technology, the thermal management system of vehicles has become more and more complex. It usually integrates several major parts such as the cabin, battery, motor and electronic control. The heat exchange is achieved through the refrigerant fluid, and finally each functional area is within the target temperature range.

[0063] However, the 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, an embodiment of the present invention is proposed. 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, wherein 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 includes at least fourteen interfaces, and at least fourteen interfaces are mutually separated and arranged on the second valve body 102. 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 an external force, the conversion grooves 1031 are switched to form contact with the interface group 1021 to switch the pipeline connection state corresponding to different interfaces. Therefore, only one fourteen-way valve 1 is needed to be arranged, and each load in the thermal management system is directly connected to the fourteen-way valve 1, so as to meet the pipeline switching requirements, simplify the pipeline design of the system, and greatly reduce the assembly space required for the pipeline.

[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 in 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 an 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 the 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 different interfaces in the second valve body 102 are separated from each other, that is, they are not connected to each other, and each interface of the interface group 1021 is respectively connected to the first valve body 101. 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 force of an external force, the different conversion grooves 1031 on the valve core 103 respectively come into 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, thereby realizing the switching requirements of all pipelines in the thermal management system, simplifying the pipeline design of the thermal management system, and greatly reducing the assembly space required for the pipeline.

[0068] An optional embodiment of the invention, 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 the embodiment of the present invention, the valve core 103 may be a cylindrical structure, so that the rotation of the valve core 103 can be facilitated, and the center of gravity of the valve core 103 can be located on the central axis of the valve core 103, so that the external rotary motion output device can drive the valve core 103 to rotate, and the radial load of the rotary motion output device can be reduced. In some embodiments, the rotary motion output device may include but is not limited to a servo motor, a stepper motor, etc. The clearance fit between the valve core 103 and the first valve body 101 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 will not form a pipeline communication state.

[0070] An optional embodiment of the invention, referring to Figure 4 , Figure 5 as well as Figure 6As shown, 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, and the centers of two adjacent groups of the conversion grooves 1031 form a first angle α with the valve core 103. Each time the valve core 103 rotates by the first angle, one group of the conversion grooves 1031 is switched to form contact with the interface group 1021.

[0071] In the 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 another group of the conversion grooves 1031 to form contact with the interface group 1021, so that the pipeline connection state 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 state between different pipelines can be controlled through the communication between different grooves.

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

[0075] First, a connecting hole is opened between two adjacent grooves to achieve the connection 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 taken as a whole to process a groove, so that the groove covers the two interfaces corresponding to the two grooves at the same time. As a result, the groove designs corresponding to different groups of conversion grooves 1031 are different from each other, so that the switching of different operation modes of the thermal management system is realized through the mutual contact and cooperation between different groups of conversion grooves 1031 and the interface group 1021.

[0077] An optional embodiment of the invention, 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 the 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 at the end of the second valve body 102 away from the first valve body 101 is larger, and a larger assembly space for each interface can be reserved. 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 is 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, thereby being applicable to thermal management systems with more operating mode switching scenarios. On the basis of meeting the pipeline switching scenarios with higher complexity, 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 invention, 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 the embodiment of the present invention, considering the processing convenience of the conversion groove 1031 and the neatness of the arrangement of the pipeline, the cross-sectional shape of the second valve body 102 along the axial direction of the valve core 103 is a rectangle. The interface group 1021 is distributed in an array on the second valve body 102. Among them, the array distribution can be understood as a uniform arrangement of multiple rows and columns. In some embodiments, at least fourteen interfaces on the interface group 1021 can be distributed according to 4 rows and 5 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. Its distribution is Figure 7 As shown, some areas can be set as blind ends (i.e., no interfaces are set). In the case of a blind end, a corresponding area on the valve core 103 should also be provided with a groove, so that the interfaces on the four sides of the blind end can be easily connected. For example, the second row of the second valve body 102 is set as a blind end. The second row on the valve core 103 is also provided with a groove, connecting some interfaces of the first row and the third row. Those skilled in the art can also determine the specific number of interfaces to be opened according to actual pipeline requirements, and no excessive restrictions are made here.

[0081] An optional embodiment of the invention, referring to Figure 1 , Figure 2 as well as Figure 3 As shown, a driving shaft 1032 is disposed 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 the embodiment of the present invention, a driving shaft 1032 is disposed at the center of one end surface of the valve core 103, and the driving shaft 1032 penetrates the first valve body 101 and extends outside the first valve body 101. The driving shaft 1032 is coaxially fixed with an output shaft of an external rotary motion output device, so that when the output shaft of the rotary 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 of the embodiments of the invention, and further 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 liquid inlet and outlet of the evaporator 7 are respectively connected to the interface group 1021, the liquid inlet and outlet of the condenser 2 are respectively connected to the interface group 1021, the liquid inlet and outlet of the first heat exchanger 3, the liquid inlet and outlet of the second heat exchanger 4, and the liquid 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 an 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 the 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.

The liquid inlet of the third heat exchanger 8 can be communicated with the thirteenth interface 102113 of the interface group 1021, and the liquid outlet of the third heat exchanger 8 can be communicated with the fourteenth interface 102114 of the interface group 1021.

[0087] In the 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 working, the compressor 9 compresses the low-temperature and 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 and then sent to the evaporator 7, where it absorbs heat 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 exchange device 5 is a device for heat exchange with the battery in the vehicle, which can be a cooling plate with a cooling channel, a cooling pipe or other structure, and is in contact with the battery to achieve heat exchange. The electric control heat exchange device 6 is a device for heat exchange with the control board, motor and other devices in the vehicle. Like the battery heat exchange device 5, it can be a cooling plate with a cooling channel, a cooling pipe or other structure.

[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 to store the cooling water after heat exchange.

[0091] In the embodiment of the present invention, in order to provide the flow power of 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 arranged between the liquid outlet of the evaporator 7 and the interface group 1021, and / or a water pump 12 may be arranged between the liquid inlet of the condenser 2 and the interface group 1021. Here, there is no excessive limitation on the installation position of the water pump 12.

[0092] In an optional embodiment of the invention, referring to Fig. 9 and Fig.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 communicated with the liquid inlet of the third heat exchanger 8 , the liquid outlet of the third heat exchanger 8 is communicated with the liquid inlet of the electrically controlled heat exchange device 6 , and the liquid outlet of the electrically controlled heat exchange device 6 is communicated with the liquid inlet of the evaporator 7 .

[0094] In the embodiment of the present invention, the above-mentioned operation mode can be regarded as the first operation mode of the heat pump air conditioner, and the fluid path connection between different interfaces is realized by the blocking effect of the valve core 103 on the interface fluid path of the interface group 1021 and the conduction effect of different grooves on the interface. Among them, the high-temperature cooling water flows out of the condenser 2 and flows into the second heat exchanger 4, then flows into the battery heat exchange device 5 through the second heat exchanger 4, and finally flows into the condenser 2 for circulation, which 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 outside is at a low temperature, or heating the battery and the cabin during the vehicle startup phase.

[0095] The low-temperature cooling water flows out of the evaporator 7 and flows to the third heat exchanger 8 located outside the vehicle, then flows from the third heat exchanger 8 to the electric-controlled heat exchange device 6, and finally flows from the electric-controlled heat exchange device 6 to the evaporator 7 for circulation. The low-temperature cooling water obtained by the operation of the evaporator 7 is used to further cool down through the third heat exchanger 8 located in the low-temperature environment outside the vehicle, so that sufficient cooling capacity can be provided for the electric-controlled heat exchange device 6 to dissipate heat and improve the 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 that the cabin does not need to be heated.

[0097] In an optional embodiment of the invention, referring to Fig.11 and Fig.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 communicated with the liquid inlet of the third heat exchanger 8 , the liquid outlet of the third heat exchanger 8 is communicated with the liquid inlet of the electrically controlled heat exchange device 6 , and the liquid outlet of the electrically controlled heat exchange device 6 is communicated with the liquid inlet of the evaporator 7 .

[0099] In the embodiment of the present invention, the above operation mode can be regarded as the second operation mode of the heat pump air conditioner, and the high-temperature cooling water flows out of the condenser 2 and flows to the second heat exchanger 4, and then flows into the condenser 2 for circulation after passing through the second heat exchanger 4. Thus, the condenser 2 provides heat for the second heat exchanger 4 located in the vehicle. For example, when the vehicle cabin needs to be heated when the vehicle is parked for rest in winter, the second operation mode is enabled.

[0100] The low-temperature cooling water flows out of the evaporator 7 and flows to the third heat exchanger 8 located outside the vehicle, then flows to the electric-controlled heat exchange device 6 through the third heat exchanger 8, and finally flows from the electric-controlled heat exchange device 6 to the evaporator 7 for circulation. Thus, the electric-controlled waste heat can be recovered and flowed to the evaporator 7, and when the vehicle's air intake grille is closed, the third heat exchanger 8 does not perform forced convection heat exchange with the external environment, so that the vehicle cabin can be heated simultaneously by the third heat exchanger 8 and the second heat exchanger 4.

[0101] In an optional embodiment of the invention, referring to Fig.13 and Fig.14As 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 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 communicated with the liquid inlet of the first heat exchanger 3 , the liquid outlet of the first heat exchanger 3 is communicated with the liquid inlet of the battery heat exchange device 5 , and the liquid outlet of the battery heat exchange device 5 is communicated with the liquid inlet of the evaporator 7 .

[0103] In the embodiment of the present invention, the above operation mode can be regarded as the third operation mode of the heat pump air conditioner, wherein the high-temperature cooling water flows out of the condenser 2 and flows into the electric-controlled heat exchange device 6, then flows from the electric-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 the summer when the temperature is high or when the vehicle is driving for a long time and the cabin, battery, electric control, etc. need to be cooled, the high-temperature cooling water can be used to cool the motor and electric control and other devices.

[0104] The low-temperature cooling water flows out of the evaporator 7 and flows into the first heat exchanger 3, then flows from the first heat exchanger 3 to the battery heat exchange device 5, and finally flows from the battery heat exchange device 5 to the evaporator 7 for circulation. Thus, the low-temperature cooling water in the evaporator 7 can be used to cool the vehicle cabin and the battery.

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

[0106] In an optional embodiment of the invention, referring to Fig.15 and Fig.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 operation mode can be regarded as the fourth operation 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 battery and / or electronic control have waste heat that can be recovered to the cabin for heating. 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. Then the operating efficiency of the system is improved to achieve the purpose of heat recovery.

[0109] Alternatively, in this operating mode, the ambient temperature is used to dissipate heat during vehicle driving or battery charging, the air conditioning system is not running, the electronic control and the battery can be cooled by the ambient temperature, and the air conditioning system is not turned on. Among them, the high-temperature cooling water can stop circulating, and the low-temperature cooling water continues to circulate through the setting of the water pump 12, and the evaporator 7 does not work. Therefore, the temperature difference between the ambient temperature and the cooling water in the battery and the electronic control can be used for heat dissipation.

[0110] In an optional embodiment of the invention, referring to Fig.17 and Fig.18 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 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 operation mode can be regarded as the fifth operation mode of the heat pump air conditioner, and the high-temperature cooling water flows out of the condenser 2 and flows to the electric-controlled heat exchange device 6, and then flows from the electric-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. The low-temperature cooling water flows out of the evaporator 7 and flows to the first heat exchanger 3, and then flows from the first heat exchanger 3 to the evaporator 7 for circulation.

[0113] When the vehicle is in motion or parked for a rest, if the cabin and the electric control need to be cooled, this operation mode can be activated. The high-temperature cooling water from the condenser 2 flows through the electric control heat exchange device 6 to cool the electric control, and the cabin is cooled by the combination of the third heat exchanger 8 and the first heat exchanger 3.

[0114] In an optional embodiment of the invention, referring to Fig.19 and Fig. 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 communicated with the liquid inlet of the first heat exchanger 3 , the liquid outlet of the first heat exchanger 3 is communicated with the liquid inlet of the battery heat exchange device 5 , and the liquid outlet of the battery heat exchange device 5 is communicated with the liquid inlet of the evaporator 7 .

[0116] In the embodiment of the present invention, the above operation mode can be regarded as the sixth operation 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. Then it flows from the second heat exchanger 4 to the electric-controlled heat exchange device 6, and finally flows from the electric-controlled heat exchange device 6 to the third heat exchanger 8, and flows to the condenser 2 for circulation. Low-temperature cooling water flows out of the evaporator 7 and flows into the first heat exchanger 3, and then flows from the first heat exchanger 3 to the battery heat exchange device 5, and finally flows to the evaporator 7 for circulation. This operation mode is suitable for scenes where the external environment humidity is high and the cabin needs to be dehumidified. Among them, the second heat exchanger 4 cools down the electric-controlled heat exchange device 6. The third heat exchanger 8 reduces the temperature of the high-temperature cooling water, recovers the battery waste heat through the battery heat exchange device 5, and increases the temperature of the low-temperature cooling water. Thereby, the evaporation efficiency of the evaporator 7 and the condensation efficiency of the condenser 2 can be improved, and the dehumidification efficiency of the air conditioner can be comprehensively improved.

[0117] For example, in one embodiment, the heat pump air conditioner can be switched among the above six operating modes, and 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 embodiment of the present invention further discloses a vehicle, which may include the heat pump air conditioner described in any one of the above invention embodiments. 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 by opening a grille.

[0119] In summary, the embodiment of the present invention discloses a fourteen-way valve 1, a heat pump air conditioner and a vehicle. The embodiment of the present invention 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 the end of the second valve body 102 away from the first valve body 101 is provided with an interface group 1021, wherein the interface group 1021 includes at least fourteen interfaces, and at least fourteen interfaces are mutually separated and arranged on the second valve body 102. 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 an external force, the conversion grooves 1031 are switched to form contact with the interface group 1021 to switch the pipeline connection state corresponding to different interfaces. Therefore, only one fourteen-way valve 1 is needed to be arranged, and each load in the thermal management system is directly connected to the fourteen-way valve 1, so as to meet the pipeline switching requirements, simplify the pipeline design of the system, and greatly reduce the assembly space required for the pipeline.
