Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, terms of orientation such as "upper, lower, top, and bottom" are defined with reference to the orientation of the drawing. "inner and outer" refer to the inner and outer of the contour of the associated component. Furthermore, the terms "first," "second," and the like, as used in embodiments of the present disclosure, are used for distinguishing one element from another and not for order or importance.

As mentioned above, in the related art, since the prior art vehicle thermal management system has the drawbacks of complicated piping arrangement and low integration, it is also disadvantageous to meet the increasing demands of the reversing mode of the vehicle thermal management system.

In view of this, the present disclosure provides a thermal management integrated module, a vehicle thermal management system, and a vehicle, as shown in fig. 1 to 13.

The vehicle thermal management system may include, among other things, a thermal management device that may include, but is not limited to, any one or more of an engine 680, a battery pack 640, a battery heat exchanger 670, a radiator 630 (e.g., a low temperature radiator), a motor electronic control unit 620, and the like, and a thermal management integrated module. The thermal management integrated module is provided with corresponding interfaces respectively connected with an engine 680, a battery pack 640, a battery heat exchanger 670, a radiator 630, a motor electronic control unit 620 and the like, so as to be connected with each thermal management device into various flow paths, and realize various preset modes of a vehicle thermal management system.

As shown in fig. 1 to 5, the thermal management integrated module provided by the present disclosure may include a flow channel plate 300, a four-way valve 200 and a five-way valve 100, where a plurality of interfaces are provided on the thermal management integrated module, a plurality of flow channels communicating with corresponding interfaces are provided in the flow channel plate 300, and the four-way valve 200 and the five-way valve 100 are respectively disposed on the flow channel plate 300 and are used for controlling on-off of corresponding flow channels in the flow channel plate 300, where interfaces connected with at least one or more of a cooling liquid flow channel where an engine 680 is located, a cooling liquid flow channel where a battery pack 640 is located, and a cooling liquid flow channel where a motor electronic control unit 620 is located are provided in the plurality of interfaces.

In the thermal management integrated module provided by the present disclosure, the flow channel plate 300 is provided with the flow channel instead of the existing connecting pipeline, which is beneficial to reducing the design of the connecting pipeline in the thermal management system and simplifying the structure of the thermal management system of the vehicle. In addition, the design of the flow channel in the flow channel plate 300 is also beneficial to reducing the weight of the heat management integrated module, thereby being beneficial to the design of light weight of the whole vehicle. Moreover, since the four-way valve 200 and the five-way valve 100 are integrated on the flow channel plate 300, on one hand, the integration degree of the thermal management integrated module can be improved, and on the other hand, the thermal management integrated module can be constructed into a reversing structure, and multiple reversing modes can be realized by controlling the opening and closing of the respective valve ports of the four-way valve 200 and the five-way valve 100, when the thermal management integrated module is applied to a vehicle thermal management system, the requirements of the thermal management system on the multiple reversing modes can be realized, and therefore, the multiple thermal management modes of the vehicle thermal management system can be realized.

In the present disclosure, the thermal management integrated module may be applied to a thermal management cooling circulation system of a vehicle, and may also be applied to other occasions where it is necessary to change the flow direction of a liquid, such as a hydraulic system, a water circulation system, and the like.

In addition, it is understood that the object of the application of the thermal management integrated module provided in the present disclosure may be a vehicle, and may also be applied to other devices that need to change the flow direction of the liquid, which is not limited in this disclosure.

In the present disclosure, it is understood that the positions of the plurality of ports are not limited, and some ports may be located on the flow field plate 300 and some ports may be located on the four-way valve 200 and the five-way valve 100.

The present disclosure is not limited to the number of multiple interfaces and may depend on the number of thermal management devices that need to be connected. Alternatively, as shown in fig. 1 and 2, in one embodiment of the present disclosure, the plurality of ports includes a first port 1, a second port 2, a third port 3, and a fourth port 4, the first port 1 is configured to be connected to a coolant outlet of the radiator 630, the second port 2 is configured to be connected to an inlet end of a first coolant flow path in which the motor electronic control unit 620 and the first pump 610 are connected in series, the third port 3 is configured to be connected to an outlet end of the first coolant flow path, the third port 3 is connected to the fourth port 4, and the fourth port 4 is configured to be connected to a coolant inlet of the radiator 630, wherein the first port 1 may be configured as a first inlet of the five-way valve 100, and the second port 2 is configured as a first outlet of the five-way valve 100.

So designed, the radiator 630 may be used to naturally cool the motor electrically, at which time the first pump 610 may be started and the first inlet and the first outlet of the five-way valve 100 may be connected. Thus, referring to fig. 5, after passing through the second port 2, the cooling liquid flowing from the first port 1 may flow into the first pump 610 and the motor electronic control unit 620, then enter the third port 3, and communicate with the radiator 630 through the fourth port 4, and the cooling liquid flowing through the radiator 630 returns to the first port 1 after cooling, so as to implement circulation, thereby implementing cooling of the motor electronic control unit 620.

The positions of the first pump 610 and the motor electronic control unit 620 in the first cooling fluid flow path are not limited, alternatively, referring to fig. 5, the second port 2 may be connected to a fluid inlet of the first pump 610, a fluid outlet of the first pump 610 is connected to a cooling fluid inlet of the motor electronic control unit 620, and a cooling fluid outlet of the motor electronic control unit 620 is connected to the third port 3.

The specific manner in which the third interface 3 and the fourth interface 4 are connected is not limited by the present disclosure. Alternatively, as shown in fig. 2 and 3, in one embodiment of the present disclosure, the plurality of internal flow channels includes a first flow channel 331, and the third port 3 and the fourth port 4 are directly communicated through the first flow channel 331. Thus, the external pipeline and the heat management integrated module are saved, and the weight reduction is facilitated.

It is understood that in other embodiments of the present disclosure, the two may be connected using an external connection.

Referring to fig. 2 to 5, the plurality of ports may further include a fifth port 5, a sixth port 6, a seventh port 7, and an eighth port 8, the fifth port 5 being for connecting an inlet end of a second coolant flow path in which the battery pack 640 and the second pump 650 are connected in series, the sixth port 6 being for connecting an outlet end of the second coolant flow path, the sixth port 6 being for connecting the seventh port 7 through a flow path in which the four-way valve 200 is located, the seventh port 7 being for connecting a coolant inlet of the battery heat exchanger 670, the eighth port 8 being for connecting a coolant outlet of the battery heat exchanger 670, the eighth port 8 being for connecting the fifth port 5, wherein the sixth port 6 is configured as a first inlet of the four-way valve 200, and the seventh port 7 is configured as a first outlet of the four-way valve 200.

So designed, the battery heat exchanger 670 can be used for cooling the battery independently, at this time, the second pump 650 can be started, so that the cooling liquid flowing out of the fifth interface 5 can enter the sixth interface 6 after passing through the second pump 650 and the battery pack 640, and is communicated with the battery heat exchanger 670 through the seventh interface 7, the cooling liquid flowing through the battery heat exchanger 670 flows into the eighth interface 8 after being cooled, and the eighth interface 8 is connected with the fifth interface 5, and then the cooling liquid returns to the fifth interface 5 to realize circulation, so that the battery heat exchanger 670 can be used for realizing independent cooling of the battery. In order to cool the battery, the battery heat exchanger 670 may exchange heat with a cooling medium (e.g., a refrigerant in an air conditioning system) having a relatively low temperature, so as to reduce the temperature in the cooling fluid path where the battery pack 640 is located.

The location of the second pump 650 and the battery pack 640 in the second coolant flow path is not limited, and optionally, referring to fig. 5, the fifth port 5 may be connected to a liquid inlet of the second pump 650, a liquid outlet of the second pump 650 is connected to a coolant inlet of the battery pack 640, and a coolant outlet of the battery pack 640 is connected to the sixth port 6.

The first inlet of the five-way valve 100, the second inlet of the five-way valve 100, the third inlet of the five-way valve 100, the first chamber 141, the second chamber 142, and the third chamber 143 are all disposed in the first portion, and the plurality of ports (e.g., the first port 111, the second port 112, the third port 113, the fourth port 114, the fifth port 115, and the sixth port 116) of the five-way valve 100, the first outlet of the five-way valve 100, the second outlet of the five-way valve 100, the fourth chamber 151, and the fifth chamber 152 are all disposed in the second portion 102. That is, the valve body of the five-way valve 100 is a split structure comprising two halves, i.e., the first portion and the second portion 102, which allows the two portions to be separately machined and then joined together, which facilitates machining the internal structure of the valve body, e.g., the various inlets, outlets, ports, and chambers of the five-way valve 100.

The forming manner of the first accommodating cavity 141, the second accommodating cavity 142 and the third accommodating cavity 143 is not limited in the present disclosure, optionally, as shown in fig. 3, 6 and 7, in one embodiment of the present disclosure, a first chamber 140 and two first partition plates disposed at intervals in the first chamber 140 are disposed in the first portion, a first accommodating cavity 141 is defined between one of the two first partition plates and an inner wall of the first chamber 140, a second accommodating cavity 142 is defined between the two first partition plates, and a third accommodating cavity 143 is defined between the other of the two first partition plates (e.g., the first partition plate located at the left side in the direction of the drawing in fig. 5) and the first chamber 140. A second chamber 150 and a second partition within the second chamber 150 are disposed within the second portion 102, the second partition dividing the second chamber 150 into a fourth volume 151 and a fifth volume 152.

The manner in which one first chamber 140 is divided into three chambers by two first partitions and one second chamber 150 is divided into two chambers by one second partition can make the arrangement between the chambers on the first portion or the second portion 102 relatively compact, and at the same time, facilitate processing.

In the present disclosure, how the first actuating assembly 20 moves the spool assemblies 30 is not limited as long as it can move the spool assemblies 30, and for example, a linear power source, such as a first driving motor 410 (see fig. 1), a hydraulic cylinder, or a pneumatic cylinder, etc., may be provided at each spool assembly 30 to drive each spool assembly 30 to move.

Alternatively, as shown in fig. 4, 9 and 10, in one embodiment of the present disclosure, the first actuating assembly 20 may include a first actuating member 21 and a plurality of first elastic members, each of the valve cartridge assemblies 30 including a valve port valve stem 31 movably disposed in a direction of its own axis, each of the first elastic members being connected between the valve body of the five-way valve 100 and the corresponding valve cartridge stem 31 to provide an elastic force for opening the valve port by the corresponding valve cartridge stem 31, the actuating member acting on the valve stem 31 to enable the valve cartridge stem 31 to overcome the elastic force provided by the corresponding elastic members to block the valve port such that when two of the three inlets are in one-to-one communication with the two outlets, the other of the three inlets is not in communication with both outlets.

Wherein the first elastic member provides an elastic force for opening the valve port and the first actuating member 21 provides a force for overcoming the elastic member to close the valve port.

Taking the direction of the drawing of fig. 1 as an example, and referring to fig. 4, under the action of the first actuating element 21, the first elastic element may be compressed, and a portion (the blocking portion 312) of the valve core rod 31 is located in the valve port of the five-way valve 100, when the valve port needs to be opened, the acting force of the first actuating element 21 on the valve core rod 31 may be relieved or reduced, and under the action of the elastic element, the valve core rod 31 moves upward, and the valve core rod 31 moves out from the valve port, so that the valve port is opened. When it is desired to close the valve port, the force applied to the upper spool bar 31 by the first actuator 21 may be increased so that the spool bar 31 closes the valve port.

In the present disclosure, the elastic member may be a compression spring, or may be a common spring, an elastic rubber member, an elastic silica gel member, a spring sheet, or other elastic mechanism, which is not limited in this disclosure.

As shown in fig. 4 and 11, the valve core rod 31 may include a blocking portion 312 for blocking the valve port, one end of the elastic member is connected to the valve body, the other end of the elastic member abuts against the blocking portion 312, and the first elastic member is used to provide an elastic force for moving the valve core rod 31 upward (i.e., toward the first actuating member 21) to open the valve port.

In the embodiment shown in fig. 1, the first chamber 140 is located below the second chamber 150, so that when the liquid flowing into the valve port from the first inlet, the second inlet or the third inlet of the five-way valve 100 moves upward from below, the pressure of the liquid can be used to provide pressure for the blocking portion 312 to disengage upward from the valve port, thereby assisting the first elastic member to open the blocking portion 312. Therefore, in the same case, the requirement for the elastic force of the elastic member is relatively small. In addition, under the action of the auxiliary force provided by the liquid, when the elastic force of the elastic member is insufficient, the valve port can still be normally opened, and the reliability of the five-way valve 100 can be improved.

In order to improve the tightness of the valve port, optionally, as shown in fig. 4 and 11, in an embodiment of the present disclosure, an annular groove 311 is provided on an outer peripheral surface of the blocking portion 312, each valve element assembly 30 further includes a sealing ring 32, the sealing ring 32 is disposed in the annular groove 311, and an outer periphery of the sealing ring 32 is tightly used for sealing contact with an inner wall of the valve port, so that the tightness of the valve port can be improved, the risk of internal leakage is reduced, and further, the opening degree of the valve port can be accurately controlled.

Referring to fig. 2 and 6, one end of the first elastic member is connected to the flow channel plate 300, and may specifically be connected to the first plate 310, and a plurality of first avoidance passages 1021 are provided on the second portion 102, where the first avoidance passages 1021 are used for the spool rod 31 of the spool assembly 30 of the five-way valve 100 to pass through so as to cooperate with the actuating member.

The specific structure of the first actuator 21 is not limited in the present disclosure as long as the first actuator 21 is capable of actuating the valve stem 31 to move, alternatively, as shown in fig. 9 and 10, in one embodiment, the first actuator 21 is rotatably disposed on the valve body of the five-way valve 100 about its own rotation axis, for example, the first actuator 21 is rotatably disposed on the valve body of the five-way valve 100 by the first rotation shaft 215, the first actuator 21 and the valve stem 31 together constitute a cam transmission mechanism, that is, the first actuator 21 may be configured as a cam, and the plurality of valve ports are circumferentially spaced about the rotation axis of the first actuator 21, that is, on a projection plane perpendicular to the axis of the valve ports, on which projection plane the plurality of valve ports are located on the circumference of the same circle. The first actuator 21 is formed with a plurality of abutments having different heights on a face thereof facing the valve body assembly 30, the plurality of abutments being configured to selectively abut against the tips of the plurality of valve stems 31 when the first actuator 21 rotates about its own axis to adjust the positions of the plurality of valve stems 31 within the corresponding valve ports.

It is understood that the abutment portions (e.g., the first abutment portion 211, the second abutment portion 212, and the third abutment portion 213) herein protrude from the reference surface 216 of the actuator, and the "height" refers to the height protruding from the reference surface 216 of the actuator.

In the disclosure, since the plurality of valve ports are circumferentially spaced around the rotation axis of the actuator (i.e., the axis of the first rotary shaft 215), when the first actuator rotates to a different abutment portion, the top end of the valve core rod 31 in the different valve ports can be abutted, so as to realize opening and closing of the corresponding valve ports.

In the present disclosure, the rotation angle of the actuator may be controlled according to the center angle of the interval between two adjacent valve ports among the plurality of valve ports to achieve the preset communication between the inlet and the outlet of the five-way valve 100. The valve core rods 31 of the valve core assemblies 30 can be simultaneously driven to move through the actuating piece, so that the integration level of the five-way valve 100 is improved, the structure of the five-way valve 100 is simplified, and the volume is reduced.

Alternatively, as shown in fig. 10, in one embodiment of the present disclosure, the first port 111, the second port 112, the third port 113, the fourth port 114, the fifth port 115, and the sixth port 116 are uniformly circumferentially distributed about the own rotation axis of the actuator 21, that is, on the valve body of the five-way valve 100, the plurality of ports of the five-way valve may be uniformly distributed about the axis of the first rotation shaft 215, with a circumferential spacing of 60 ° between adjacent two of the first port 111, the second port 112, the third port 113, the fourth port 114, the fifth port 115, and the sixth port 116. The first actuating member is formed with a guide path 214 on a surface facing the valve stem 31, the plurality of abutments include a first abutment 211, two second abutments 212 and a third abutment 213 provided on the guide path 214, the first abutment 211 and the third abutment 213 are configured such that when being in abutment with the top end of the valve stem 31, the valve port is in a closed state, the second abutment 212 is configured such that when being in abutment with the top end of the valve stem 31, the valve port is in a fully open state, on a projection surface perpendicular to a rotation axis of the actuating member, projections of the first abutment 211, the second abutment 212 and the third abutment 213 are located on a circumference of the same circle, and the first abutment 211 and the third abutment 213 are located on opposite sides of a line connecting the two second abutments 212, respectively, and an angle of a cam center angle α between the projections of the two second abutments 212 and the projections of the first abutment 211 is 60 °, wherein when the two second abutments 212 are in abutment with the valve stem 31 in abutment with two of the plurality of valve ports, the first abutment 211 and the valve port is in a six-way when the other valve port is in a state when the two second abutments 211 and the valve port are in a remaining state, the valve port is in a six-port in abutment state when being in abutment with the valve port and the valve port in a remaining valve port.

Based on this, by rotating the first actuator 21 so that the tip end of the spool rod 31 slidably abuts against the guide path 214, the tip end of the spool rod 31 can selectively abut against positions of different heights on the guide path 214, and by changing the positions at which the first abutment 211, the second abutment 212, and the third abutment 213 of the actuator abut against the tip end of the spool rod 31, the position of the spool rod 31 within the valve port of the reversing structure can be changed, whereby opening and closing of the corresponding valve port can be achieved.

By such design, on the one hand, smooth rotation of the first actuating member 21 is facilitated, and on the other hand, the moving distance of the valve core rod 31 of the valve port in the valve port is controlled gradually and excessively, so that the opening degree of the valve port can be controlled, and the flow area of the valve port position can be adjusted, which is beneficial to enabling the five-way valve 100 to have more working modes.

In this disclosure, the first actuating element 21 may include a body 203, a first arc-shaped protrusion 201 and a second arc-shaped protrusion 202 disposed on a reference surface 216 of the body 203, an annular protrusion with a notch is defined between the first arc-shaped protrusion 201 and the second arc-shaped protrusion 202, two ends of the first arc-shaped protrusion 201 and two ends of the second arc-shaped protrusion 202 are spaced apart to define the notch, where the notch is a second abutment 212, the first abutment 211 is a first abutment plane located on a side of the first arc-shaped protrusion 201 away from the reference surface 216, and the third abutment 213 is a second abutment plane located on a side of the second arc-shaped protrusion 202 away from the reference surface 216. Optionally, the first abutting surface and the notch are in transition through a smooth surface, and the second abutting surface and the notch are in gradual transition through a smooth surface.

In the present disclosure, in order to precisely control the rotation angle of the first actuator 21, as shown in fig. 6 and 9, the five-way valve 100 is provided with a first stop structure 40, and the first stop structure 40 is used to define the rotation angle of the first actuator 21, so that the first actuator 21 rotates between an initial angle position to a preset maximum rotation angle position, so as to reset the first actuator 21 to the initial angle position.

The first blocking structure 40 is used as a reset stop structure, and in the embodiment of driving the first actuating member 21 by adopting the motor, by setting the first blocking structure 40, the occurrence of the risk of mode confusion in long-term use caused by the fact that the rotation angle of the actuating member cannot be accurately calibrated can be avoided, so that the reliability of reversing the reversing structure can be improved, and unnecessary system faults can be avoided. When the first actuator 21 is switched from the above first commutation mode to the sixth commutation mode, the first actuator 21 may be reset to the initial position first, and the first actuator 21 may be rotated to a predetermined position, for example, to a 60 ° angular position, a 120 ° angular position, a 180 ° angular position, a 240 ° angular position, and a 300 ° angular position.

The specific structure of the first stop structure 40 is not limited in the present disclosure, as long as the limit requirement on the first actuator 21 can be met. Alternatively, as shown in fig. 6 and 9, in one embodiment of the present disclosure, the first stopper structure 40 includes a first boss 41 provided on a side of the first actuator 21 facing the valve stem 31 and a first stopper 42 provided on the valve body, the first stopper 42 having a first stopper surface 421 and a second stopper surface 422 connected at opposite sides, and in an initial angular position (e.g., 0 ° angular position), one side of the first boss 41 abuts the first stopper surface 421, at which time the first actuator 21 is restricted from rotating. In the maximum rotation angle position (for example, 300 ° angle position), the other side of the first projection 41 abuts against the second stop surface 422, and the first actuator 21 is restricted from rotating.

The specific structure of the four-way valve 200 is not limited in this disclosure, alternatively, as shown in fig. 1 to 5 and 8, in one embodiment of the disclosure, the four-way valve 200 includes a second actuating assembly 240 and a plurality of second valve core assemblies 30, the plurality of interfaces includes interfaces configured as an inlet and an outlet of the four-way valve 200, an internal channel is formed between the inlet and the outlet of the four-way valve 200, a plurality of valve ports are formed on the internal channel, each valve core assembly 30 is movably disposed at a corresponding valve port, and the second actuating assembly 240 is used to move the valve core assemblies 30 in the valve ports to open or close the valve ports, thereby realizing the on-off of the corresponding internal channel.

Based on this, the following various reversing modes of the four-way valve 200 can be realized by controlling the positions of the valve core rods 31 of the plurality of valve core assemblies 30 on the respective corresponding valve ports by the actuating assemblies, which is beneficial to meeting the increasing reversing demands of the vehicle heat pipe system. For example, a reversing mode is implemented in which the first inlet communicates with the first outlet, the second inlet communicates with the first outlet, and the second inlet communicates with the second outlet. Therefore, the function of switching the liquid flow direction is realized, and various reversing modes can be realized.

It is to be understood that the number of ports of the four-way valve 200 is not limited in this disclosure, and may be any suitable number, depending on the number of internal flow channels.

As shown in fig. 2 and 3, in one embodiment of the present disclosure, four-way valve 200 may include seventh valve port 2110, eighth valve port 2120, ninth valve port 2130, and tenth valve port 2140, with the interior of the valve body having sixth chamber 221 and seventh chamber 222 disposed independently, the first inlet communicating with sixth chamber 221, the second inlet communicating with seventh chamber 222, and sixth chamber 221 and seventh chamber 222 communicating with the first outlet and the second outlet of four-way valve 200, respectively, through corresponding valve ports.

By providing separate sixth and seventh plenums 221 and 222, it is possible to avoid interaction between the liquids entering the valve body from the first inlet (sixth port 6) of the four-way valve 200 and the second inlet (eleventh port 11) of the four-way valve 200.

Optionally, as shown in fig. 8, the valve body further has an eighth containing cavity 231 and a ninth containing cavity 232 that are independently arranged, the first outlet (seventh interface 7) of the four-way valve 200 is communicated with the eighth containing cavity 231, the second outlet (fourth interface 4) of the four-way valve 200 is communicated with the ninth containing cavity 232, the sixth containing cavity 221 is communicated with the eighth containing cavity 231 through an eighth valve port 2120, the sixth containing cavity 221 is communicated with the ninth containing cavity 232 through a ninth valve port 2130, the seventh containing cavity 222 is communicated with the eighth containing cavity 231 through a seventh valve port 2110, and the seventh containing cavity 222 is communicated with the ninth containing cavity 232 through a tenth valve port 2140.

The sixth containing cavity 221, the seventh containing cavity 222, the eighth containing cavity 231 and the ninth containing cavity 232 all belong to the internal flow channels of the first valve body, and the sixth containing cavity 221 and the seventh containing cavity 222 respectively share the flow channels of the eighth containing cavity 231 and the ninth containing cavity 232 communicated with the two outlets, so that the structure of the four-way valve 200 is simplified, and the processing difficulty of the internal flow channels is reduced.

As shown in fig. 1 and 2, the first valve body may include a third portion and a fourth portion 202 that are mutually opposite, where the third portion is a part of the flow channel plate 300, the first inlet of the four-way valve 200 and the second inlet, the sixth cavity 221 and the seventh cavity 222 of the four-way valve 200 are all disposed in the third portion, and the first outlet of the four-way valve 200 and the second outlet, the eighth cavity 231 and the ninth cavity 232 of the four-way valve 200 are all disposed in the fourth portion 202. That is, the first valve body is a split structure including two halves, i.e., the third portion and the fourth portion 202, which allows the two portions to be separately processed and then joined, and the processing manner facilitates processing the internal structure of the first valve body, for example, processing each inlet, outlet, valve port and each cavity of the four-way valve 200.

The forming manner of the sixth chamber 221, the seventh chamber 222, the eighth chamber 231 and the ninth chamber 232 is not limited in the present disclosure, and optionally, as shown in fig. 3, in one embodiment of the present disclosure, a third chamber 220 and a third partition plate located in the third chamber 220 are disposed in the third portion, and the third chamber 222 is partitioned into the sixth chamber 221 and the seventh chamber 222 by the third partition plate. A fourth chamber 230 and a fourth partition within the fourth chamber 230 are disposed within the fourth portion 202, the fourth partition dividing the fourth chamber 230 into an eighth pocket 231 and a ninth pocket 232. By such a design, the arrangement between the plurality of pockets on the third or fourth portion 202 may be made relatively compact, while also facilitating ease of manufacture.

There is no limitation in the present disclosure as to how the second actuating assembly 240 moves the spool assemblies 30, as long as it can move the spool assemblies 30, for example, a linear power source such as a motor, a hydraulic cylinder, or a pneumatic cylinder may be provided at each spool assembly 30 to drive each spool assembly 30 to move.

Alternatively, the valve core assembly 30 of the four-way valve 200 may be the same as the valve core assembly 30 of the five-way valve, each valve core assembly 30 includes a valve core rod 31 movably penetrating the valve body along its axis direction, the actuating assembly includes a second actuating member 241 and a plurality of second elastic members, each second elastic member is connected between the valve body of the four-way valve 200 and the corresponding valve core rod 31 to provide an elastic force for opening the valve port, and the second actuating member 241 acts on the valve core rod 31 to enable the valve core rod 31 to overcome the elastic force provided by the corresponding second elastic member to block the valve port.

In this embodiment, the second elastic member provides an elastic force for opening the valve port, and the second actuating member 241 provides a force for overcoming the second elastic member to close the valve port.

Taking the direction of the drawing of fig. 1 as an example, the second elastic member can be compressed under the action of the second actuating member 241, a part (the blocking portion 312) of the valve core rod 31 is located in the valve port, when the valve port needs to be opened, the acting force of the second actuating member 241 on the valve core rod 31 can be relieved or reduced, and under the action of the second elastic member, the valve core rod 31 moves upwards, and the valve core rod 31 moves out of the valve port, so that the valve port is opened. When it is desired to close the valve port, the force applied to the upper spool bar 31 by the second actuator 241 may be increased so that the spool bar 31 closes the valve port.

In the present disclosure, the second elastic member may be a compression spring, or may be a common spring, an elastic rubber member, an elastic silica gel member, a spring plate, or other elastic mechanism, which is not limited in this disclosure.

The valve core rod 31 may include a blocking portion 312 for blocking the valve port, one end of a second elastic member is connected to the first valve body, and the other end of the second elastic member abuts against the blocking portion 312, and the second elastic member is used for providing an elastic force for moving the valve core rod 31 upward (i.e., toward the second actuating member 241) to open the valve port.

In the embodiment shown in fig. 1, the third chamber 220 is located below the fourth chamber 230, so that when the liquid flowing into the valve port from the first inlet of the four-way valve 200 and the second inlet of the four-way valve 200 moves upward from below, the pressure of the liquid can provide a pressure at which the blocking portion 312 is disengaged upward from the valve port, thereby assisting the elastic member to open the blocking portion 312. Therefore, in the same case, the requirement for the elastic force of the elastic member is relatively small. Moreover, under the action of the auxiliary force provided by the liquid, when the elastic force of the elastic piece is insufficient, the valve port can still be normally opened, and the working reliability of the four-way valve 200 is improved.

In order to improve the tightness of the valve port, optionally, as shown in fig. 11, in an embodiment of the disclosure, an annular groove 311 is provided on the outer peripheral surface of the plugging portion 312, each valve core assembly 30 further includes a sealing ring 32, the sealing ring 32 is disposed in the annular groove 311, and the outer periphery of the sealing ring 32 is tightly used for sealing contact with the inner wall of the valve port, so that the tightness of the valve port can be improved, the risk of internal leakage is reduced, and the opening degree of the valve port can be precisely controlled.

One end of the second elastic member may be connected to the third portion, specifically may be connected to the first plate 310, and the fourth portion 202 is provided with a plurality of second avoidance channels 2021, where the second avoidance channels 2021 are used for passing through the spool rod 31 of the spool assembly 30 to cooperate with the second actuating member 241.

In the present disclosure, the specific structure of the second actuating element 241 is not limited, as long as the second actuating element 241 can actuate the movement of the valve stem 31, optionally, as shown in fig. 12, in an embodiment, the second actuating element 241 is rotatably disposed on the valve body of the four-way valve 200 around its own rotation axis (i.e., the axis of the second rotary shaft 244), the second actuating element 241 and the valve stem 31 together form a cam transmission mechanism, the multiple valve ports are circumferentially spaced around the rotation axis, the seventh valve port 2110, the eighth valve port 2120, the ninth valve port 2130 and the tenth valve port 2140 are located on the same circumference on a projection plane perpendicular to the axial direction of the valve ports and spaced 60 ° between adjacent two, that is, the seventh valve port 2110, the eighth valve port 2120, the ninth valve port 2130 and the ninth valve port 2130 are distributed in a semicircle, the face of the second actuating element 241 facing the first valve 31 is formed with a fourth abutment 242 and a fifth abutment 243, the valve ports are in a closed state when the top ends of the fourth abutment 242 are in abutment matched with the valve stem 31, the fifth abutment 243 are disposed on the face of the valve stem 31, the valve ports are located on the same circumference of the projection plane perpendicular to the valve stem 31, the multiple valve ports are located in the projection plane perpendicular to the fourth abutment axis, and the valve port 2130 is located on the same circumference of the valve port 31, and the fifth abutment axis is located on the fifth abutment axis, and the valve port is located on the fifth abutment axis.

In the disclosure, since the plurality of valve ports are circumferentially spaced around the rotation axis of the second actuating member 241, when the second actuating member 241 rotates to different abutment portions, the tip of the spool rod 31 in the different valve ports may abut, the opening and closing of the corresponding valve ports are realized.

So configured, by rotating the angle of second actuating member 241 to change the position of spool bar 31 in seventh port 2110, eighth port 2120, ninth port 2130 and tenth port 2140, four-way valve 200 may have the following four modes of operation:

referring to fig. 2 and 12, in the first mode of operation, second actuating member 241 is in the initial position, i.e., second actuating member 241 is in the 0 angular position, at which fifth abutment 243 engages the top end of the valve stem in seventh valve port 2110, fourth abutment 242 engages the top end of the valve stem in the remaining valve ports of four-way valve 200, i.e., seventh valve port 2110 is open, and the other valve ports are closed. In this mode, the liquid flowing into four-way valve 200 from the second inlet (eleventh port 11) of four-way valve 200 passes through seventh chamber 222, seventh valve port 2110 and eighth chamber 231 in this order, and can flow out from the first outlet (seventh port 7) of four-way valve 200.

In the second mode of operation, in which the position of the second actuator 241 is rotated counter-clockwise by 60 ° compared to the first mode, i.e., the second actuator 241 is in the 60 ° angular position, the fifth abutment 243 engages the top end of the valve stem in the eighth port 2120, the fourth abutment 242 engages the top end of the valve stem in the remaining ports of the four-way valve 200, i.e., the eighth port 2120 is open and the other ports are closed. In this mode, the liquid flowing into the four-way valve 200 from the first inlet (sixth port 6) of the four-way valve 200 passes through the sixth chamber 221, the eighth port 2120, and the eighth chamber 231 in this order, and can flow out from the first outlet (seventh port 7) of the four-way valve 200.

In the third mode of operation, in which the position of the second actuator 241 is rotated counter-clockwise 120 ° compared to the first mode, i.e., the second actuator 241 is in the 120 ° angular position, the fifth abutment 243 engages the top end of the valve stem in the ninth valve port 2130, the fourth abutment 242 engages the top end of the valve stem in the remaining ports of the four-way valve 200, i.e., the ninth valve port 2130 is open and the other ports are closed. In this mode, the liquid flowing into the four-way valve 200 from the first inlet (sixth port 6) of the four-way valve 200 passes through the sixth chamber 221, the ninth valve port 2130 and the ninth chamber 232 in this order, and can flow out from the second outlet (fourth port 4) of the four-way valve 200.

In the fourth mode of operation, in which the position of the second actuator 241 is rotated counter-clockwise 180 ° compared to the first mode, i.e., the second actuator 241 is in the 180 ° angular position, the fifth abutment 243 engages the top end of the valve stem in the tenth port 2140, the fourth abutment 242 engages the top end of the valve stem in the remaining ports of the four-way valve 200, i.e., the tenth port 2140 is open and the other ports are closed. In this mode, fluid flowing into four-way valve 200 from the second inlet of the phoenix valve (eleventh port 11) passes through seventh chamber 222, tenth port 2140, and ninth chamber 232 in that order, and may flow out of the second outlet of four-way valve 200 (fourth port 4).

In the present disclosure, in order to facilitate precise control of the angle of rotation of the second actuating member 241, a second stopper structure 250 is provided on the thermal management integrated module, and the second stopper structure 250 is used to define the angle of rotation of the second actuating member 241, so that the second actuating member 241 rotates between an initial angular position to a preset maximum angular position, so as to facilitate resetting of the second actuating member 241 to the initial angular position.

The second stop structure 250 is used as a reset stop structure, and in the embodiment of driving the second actuating member 241 by using a motor, by setting the second stop structure 250, it is possible to avoid the risk of mode confusion during long-term use caused by the fact that the rotation angle of the second actuating member 241 cannot be accurately calibrated, and therefore, the reversing reliability of the four-way valve 200 can be improved, and unnecessary system faults can be avoided. When the second actuating member 241 is switched from the above first commutation mode to the fourth commutation mode, the second actuating member 241 may be reset to the initial position first, and the second actuating member 241 may be rotated from the 0 ° angular position to the preset position, for example, to the 60 ° angular position, the 120 ° angular position, the 180 ° angular position.

The specific structure of the second stop structure 250 is not limited in the present disclosure, as long as the limit requirement on the second actuating member 241 can be met. Alternatively, as shown in fig. 2 and 12, in one embodiment of the present disclosure, the second stop structure 250 includes a second bump 251 disposed on a side of the second actuator 241 facing the stem 31 and a second stop 252 disposed on the valve body, the second stop 252 having a third stop surface 2521 and a fourth stop surface 2522, one side of the second bump abutting the third stop surface 2521 in an initial angular position (e.g., 0 ° angular position) and the other side of the second bump abutting the fourth stop surface 2522 in a maximum rotational angular position (e.g., 180 ° angular position).

In the present disclosure, as shown in fig. 1 to 3, the flow channel plate 300 includes a first plate body 310 and a second plate body 320 that are mutually opposite, and a plurality of cavities or grooves are disposed on a first surface of the first plate body 310 facing the second plate body 320 and/or a second surface of the second plate body 320 facing the first plate body 310, so that the flow channel cavity can be formed between the first surface and the second surface.

As can be seen from the rotatable angles of the five-way valve 100 and the four-way valve 200, there are 24 combinations of the thermal management integrated modules for the whole five-way valve 100+four-way valve 200+plate heat exchange, namely 6 reversing modes of the five-way valve 100 (the first actuating members 21 are respectively positioned at 0 °, 60 °, 120 °, 180 °, 240 °, 300 °) multiplied by 4 modes of the four-way valve 200 (the second actuating members are respectively positioned at 0 °, 60 °, 120 °, 180 °).

The specific structure of the flow paths of the engine 680, the motor electronic control unit 620 and the battery heat exchanger 670 is not limited in this disclosure, and referring to fig. 13, the engine 680 exchanges heat by the warm air core 690 and the flow path water heat exchanger of the PCT heater.

The flow path of the engine 680 can be connected with the flow paths of the warm air core 690 and the PTC700 heater through a four-way valve, so as to exchange heat with the water-water heat exchanger 500. The motor electronic control unit 620 may have any suitable structure, and may include a generator, an electronic control unit, etc., which is not limited in this disclosure.

The operation of several exemplary modes of operation of the vehicle thermal management system according to one embodiment of the present disclosure will now be described in detail with reference to fig. 1-5, 9-11, and 13.

For cooling the battery, referring to fig. 13, the battery heat exchanger 670 is further located in the air conditioning system, so that the cooling of the air conditioning system can be achieved by using the refrigerant heat exchange in the air conditioning system.
