[0055] Example 1

[0056] In some embodiments of the present invention, reference Figures 1 to 8, a multi-way valve, the multi-way valve has an axial direction X and a circumferential direction Y around the axial direction X, and comprises: a valve body 1, which comprises a bottom wall 1a and an annular wall 1b, the annular wall 1b is connected to the circumferential edge of the bottom wall 1a to enclose a receiving cavity 10, the bottom wall 1a has a first channel 11 and a plurality of second channels 12 arranged along the axial direction X, the plurality of second channels 12 are arranged around the first channel 11 along the circumferential direction Y; a valve core 2 installed in the receiving cavity 10, the valve core 2 has an end face 20 facing the bottom wall 1a, a first groove 201 and a second groove 202 which are not connected to each other are formed on the end face 20, the first groove 201 comprises a central groove 2011 and a circumferential groove 2012, the central groove 2011 and the projection of the first channel 11 along the axial direction X at least partially overlap, the circumferential groove 202 is provided on the end face 20, the first groove 201 comprises a central groove 2011 and a circumferential groove 2012, the central groove 2011 and the projection of the first channel 11 along the axial direction X at least partially overlap, the circumferential groove 202 is provided on the end face 20, 012 along the axial direction X at least partially overlaps with the projection of at least one second channel 12 along the axial direction X, and the projection of the second groove 202 along the axial direction X at least partially overlaps with the projection of at least two second channels 12 along the axial direction X; wherein, the valve body 1 and the valve core 2 are rotatably connected, and the valve core 2 can rotate around the axial direction X relative to the valve body 1; during the rotation process, the circumferential groove 2012 is connected with different second channels 12 in sequence, and at any moment, the circumferential groove 2012 connects at least two second channels 12 adjacent to each other in the circumferential direction Y; during the rotation process, the second groove 202 is connected with different second channels 12 in sequence, and at any moment, the second groove 202 connects at least two second channels 12 adjacent to each other in the circumferential direction Y. Specifically, when the valve core 2 rotates relative to the valve body 1, the circumferential groove 2012 on the valve core 2 will connect at least two second channels 12 adjacent to each other in the circumferential direction Y, and the central groove 2011 of the first groove 201 on the valve core 2 is always connected to the first channel 11 on the valve body 1, thereby realizing the connection of the path of "first channel 11-central groove 2011-circumferential groove 2012-each second channel 12". At this time, the first channel 11 can be connected to different second channels 12 by rotating the valve core 2 to achieve the switching of the flow path; and, when the valve core 2 rotates relative to the valve body 1, the second groove 202 on the valve core 2 can connect at least two second channels 12 adjacent to each other in the circumferential direction Y. When the valve core 2 rotates further, the second groove 202 can connect another two second channels 12 adjacent to each other in the circumferential direction Y to achieve the switching of the flow path.

[0057] In addition to switching various flow passages, the multi-way valve provided by the present invention can also adjust the flow rate of each passage. Specifically, the first groove 201 on the valve core 2 connects the first channel 11 with different second channels 12. When the valve core 2 rotates a certain angle, the area of ​​the overlapping area of ​​the projection of the circumferential groove 2012 in the first groove 201 and the second channel 12 connected thereto along the axial direction X will increase or decrease, indicating that the connecting diameter between the circumferential groove 2012 and the second channel 12 is increased or decreased at this time; it can be understood that on a flow passage, if the diameters at both ends of the passage are fixed and the liquid flow pressure is fixed, then when the diameter of a certain section inside the passage increases or decreases, the flow rate of the passage will increase or decrease accordingly; therefore, the multi-way valve provided by the present invention can adjust the flow rate by rotating the valve core 2.

[0058] It is worth noting that the area of ​​the overlapping region of the projection of the second groove 202 and at least two second channels 12 connected thereto along the circumferential direction Y along the axial direction X will also increase or decrease as the valve core 2 rotates relative to the valve body 1. At this time, the flow rate of the passage "one second channel 12-second groove 202-another second channel 12" will also increase or decrease accordingly.

[0059] The multi-way valve provided by the present invention rotates the valve core 2 so that the first groove 201 and the second groove 202 on the valve core 2 are respectively connected to different second channels 12 on the valve body 1, wherein the first groove 201 can connect the first channel 11 on the valve body 1 with different second channels 12; that is, the multi-way valve provided by the present invention can control the on-off state between each second channel 12, and the on-off state between the first channel 11 and each second channel 12 by rotating the valve core 2 within a certain angle range, thereby achieving accurate and effective control of the flow rate in and out of the multi-way valve, and also achieving accurate and effective switching of each flow path; in summary, the multi-way valve provided by the present invention has the function of switching multiple flow paths and adjusting the flow rate of each flow path, thereby solving the problems of complex and redundant structures and difficulty in regulating path switching and flow control in existing multi-way valve products.

[0060] Obviously, the multi-way valve provided by the present invention changes the size of the connecting aperture between the first groove 201 on the valve core 2 and the first channel 11 on the valve body 1 by rotating the valve core 2, and also changes the connecting aperture between the second groove 202 on the valve core 2 and the second channel 12 on the valve body 1, and can also change the second groove 202 from being connected to an original second channel 12 to being connected to another second channel 12, or connect the above-mentioned two second channels 12; obviously, the multi-way valve provided by the present invention has the advantages of easy regulation, high efficiency and reliability.

[0061] In summary, the multi-way valve provided by the present invention has the function of switching multiple flow paths and adjusting the flow size of each flow path, which solves the problems of complex and redundant structure and difficulty in regulating path switching and flow control in existing multi-way valve products.

[0062] It is worth noting that the multi-way valve provided by the present invention can be used in the thermal management system of a vehicle, the above-mentioned liquid supply mechanism can be a mechanism for providing coolant in the thermal management system, and the above-mentioned liquid using mechanism can be a vehicle battery that needs to be cooled or kept warm; the multi-way valve provided by the present invention is applied to the thermal management system of a vehicle to effectively improve the vehicle's control over battery thermal management, and to achieve the connectivity, switching, reversing and regulation of the coolant in each pipeline in the thermal management system in a more efficient manner, so as to solve the problems of large size, redundant structure, complex pipelines and excessively high cost in existing vehicle thermal management systems.

[0063] It can be understood that the specific shapes, sizes, etc. of the first channel 11, the second channel 12, the first groove 201, and the second groove 202 can be selected and adjusted according to the actual application scenario.

[0064] In some embodiments of the present invention, the first channel 11 is used to communicate with a liquid supply mechanism located outside the multi-way valve, and the second channel 12 is used to communicate with a liquid using mechanism located outside the multi-way valve. Alternatively, in other embodiments of the present invention, the first channel 11 is used to communicate with the liquid using mechanism, and the second channel 12 is used to communicate with the liquid supply mechanism. Alternatively, in other embodiments of the present invention, at least one of the second channels 12 is used to communicate with the liquid supply mechanism, and at least another of the second channels 12 is used to communicate with the liquid using mechanism. It is understandable that the multi-way valve provided by the present invention can be connected with a liquid supply mechanism and a liquid using mechanism and used in combination to form a system for driving liquid flow; wherein the liquid supply mechanism transports liquid to the interior of the multi-way valve, and then the liquid that has passed through the diversion and / or flow limiting effect of the multi-way valve flows into the liquid using mechanism again.

[0065] In some embodiments of the present invention, reference Figure 8 For the convenience of description, in the specification of the present invention, each second channel 12 is defined as a first second channel 12a, a second second channel 12b, a third second channel 12c and a fourth second channel 12d.

[0066] In some embodiments of the present invention, reference Figure 8, the first channel 11 on the valve body 1 is connected with the liquid supply mechanism, and the No. 1 second channel 12a is connected with the liquid using mechanism. The liquid in the liquid supply mechanism enters the multi-way valve via the first channel 11, and then leaves the multi-way valve from the No. 1 second channel 12a through the first groove 201 in sequence and flows to the liquid using mechanism; in some other embodiments of the present invention, the first channel 11 on the valve body 1 is connected with the liquid using mechanism, and the No. 1 second channel 12a is connected with the liquid supply mechanism. The liquid in the liquid supply mechanism enters the multi-way valve via the No. 1 second channel 12a, and then leaves the multi-way valve from the first channel 11 through the first groove 201 in sequence and flows to the liquid using mechanism. It is worth noting that, in some embodiments of the present invention, the flow rate of this part can be regulated by rotating the valve core 2, while in other embodiments, the flow rate change of this part can be ignored, which depends on the specific shape and size parameters of the first channel 11 and the first second channel 12a, and also depends on the specific rotation angle range of the valve core 2; that is, the rotation angle range of the valve core 2 can be set according to demand to control the size of the connecting aperture between the first channel 11 and the first second channel 12a, so as to control the flow rate of this passage between the first channel 11 and the first second channel 12a.

[0067] In some embodiments of the present invention, reference Figure 8, the second channel 12b, the third second channel 12c and the fourth second channel 12d on the valve body 1 are arranged adjacent to each other in sequence along the circumferential direction Y, and the second groove 202 on the valve core 2 can be simultaneously connected with the second channel 12b, the third second channel 12c and the fourth second channel 12d, and the third second channel 12c is completely connected with the second groove 202 (at this time, the projection of the third second channel 12c along the axial direction X completely falls on the projection of the second groove 202 along the axial direction X). The second channel 12b and the fourth channel 12d are at least partially connected to the second groove 202 (at this time, the projection of the second channel 12b along the axial direction X only partially overlaps with the projection of the second groove 202 along the axial direction X, and the projection of the fourth channel 12d along the axial direction X only partially overlaps with the projection of the second groove 202 along the axial direction X), and the third second channel 12c is connected to the liquid supply mechanism, and the second channel 12b and the fourth second channel 12d are respectively connected to the first liquid supply mechanism. The liquid supply mechanism is connected with the second liquid-using mechanism; the liquid from the liquid supply mechanism enters the multi-way valve through the No. 3 second channel 12c, and then leaves the multi-way valve through the No. 2 second channel 12b and the No. 4 second channel 12d respectively under the distribution and guidance of the second groove 202 of the valve core 2, and flows to the first liquid-using mechanism and the second liquid-using mechanism respectively, thereby realizing the distribution and regulation of the liquid flow; it is worth noting that when the valve core 2 rotates, the connecting caliber size of the second groove 202 and the No. 2 second channel 12b and the No. 4 second channel 12d will change (that is, the size of the overlapping area of ​​the projection of the second groove 202 and the No. 2 second channel 12b along the axial direction X changes, and the size of the overlapping area of ​​the projection of the second groove 202 and the No. 4 second channel 12d along the axial direction X also changes), so that the flow entering the first liquid-using mechanism through the No. 2 second channel 12b and the flow entering the second liquid-using mechanism through the No. 4 second channel 12d can be adjusted, so that the multi-way valve realizes the regulation and distribution of the inlet and outlet liquid flows.

[0068] It is worth mentioning that the reference Figure 8In some embodiments of the present invention, a blocking member 6 is provided between the second channel No. 2 12b and the second channel No. 3 12c, and a blocking member 6 is also provided between the second channel No. 3 12c and the second channel No. 4 12d; observing the multi-way valve along the axial direction X, when the valve core 2 rotates within a certain angle, the area of ​​the overlapping area of ​​the second groove 202 and the projection of the second channel No. 2 12b along the axial direction X will change, and the area of ​​the overlapping area of ​​the second groove 202 and the projection of the second channel No. 4 12d along the axial direction X will also change, thereby achieving the effect of "adjusting the flow rate flowing through the second channel No. 2 12b and the second channel No. 4 12d by rotating the valve core 2". In some other embodiments of the present invention, the second channel No. 2 12b is connected to the first liquid supply mechanism, the second channel No. 4 12d is connected to the second liquid supply mechanism, and the second channel No. 3 12c is connected to the liquid using mechanism. The principles of path switching and flow control in these embodiments are basically the same as those described above and will not be repeated here. It can be understood that different numbers of liquid supply mechanisms and liquid using mechanisms can be connected to the first channel 11 and each second channel 12 on the multi-way valve, respectively, and then the liquid path can be switched and the liquid flow can be regulated under the dredging and regulating action of the first groove 201 and the second groove 202 of the valve core 2 to meet different application requirements.

[0069] In some embodiments of the present invention, reference Figure 8 , the central groove 2011 and the first channel 11 are arranged concentrically in the axial direction X; the valve core 2 can rotate relative to the valve body 1, so that the circumferential groove 2012 is connected with each of the second channels 12 in sequence along the circumferential direction Y. Specifically, when the valve core 2 rotates relative to the valve body 1, the circumferential groove 2012 on the first groove 201 rotates with the central axis of the first channel 11 (along the axial direction X) as the rotation axis, and the second groove 202 rotates around the central groove 2011 along the circumferential direction Y, so that the first groove 201 is connected with different second channels 12 respectively through the circumferential groove 2012, and the communication caliber between the first groove 201 and each second channel 12 will also increase or decrease (that is, the area of ​​the overlapping area of ​​the projection of the circumferential groove 2012 and each second channel 12 along the axial direction X increases or decreases), thereby realizing the switching of the flow passage and / or the adjustment of the flow size.
