[0055] The multi-way valve of this embodiment can be applied to scenarios where a flow medium is transported through multiple channels. For example,

[0056] The multi-way valve can be applied to electric vehicles. Specifically, the interior of the electric vehicle may include a variety of management systems, such as a battery management system (BMS), a thermal management system 200 (TMS), etc. Through the cooperation of various management systems, the stable operation of various devices inside the electric vehicle can be achieved. Taking the thermal management system as an example, the thermal management system can reasonably manage the temperature of the drive motor system, the power battery, and the passenger compartment, thereby ensuring the safe operation of the power battery to the greatest extent and improving the utilization efficiency of the power battery. Specifically, the thermal management system can switch the flow medium, such as the delivery channel of the coolant, through a multi-way valve to control the temperature management on different circuits.

[0057] See also Figures 1 to 4, this embodiment provides a multi-way valve, including a valve body 1 and a valve core 9. The valve body 1 includes a side wall and a bottom wall connected to each other, and the inner side wall and the inner bottom wall of the valve body 1 enclose the inner cavity of the valve body 1. The valve core 9 is rotatably arranged in the inner cavity of the valve body 1 along its own axis, the bottom end face of the valve core 9 faces the valve body 1, and the top end face faces away from the valve body 1, and the valve core 9 and the valve body 1 are both cylindrical. A valve core flow channel is arranged on the bottom end face of the valve core 9, and the valve core flow channel includes a first valve core flow channel 91 and a second valve core flow channel 92 with the same structure and circumferentially separated. A third valve core flow channel 93 is also arranged on the bottom end face of the valve core 9, and the first valve core flow channel 91 and the second valve core flow channel 92 are connected through the third valve core flow channel 93, that is, the first valve core flow channel 91, the third valve core flow channel 93 and the second valve core flow channel 92 are connected in sequence. The first valve core flow channel 91 , the third valve core flow channel 93 and the second valve core flow channel 92 are all grooves formed on the bottom end surface of the valve core 9 and do not penetrate the valve core 9 in the axial direction.

[0058] The bottom wall of the valve body 1 is divided into the first area 11a, the second area 11b, the third area 12a, the fourth area 14a, the fifth area 13a and the sixth area 13b in the circumferential direction, each area occupies one sixth of the circumference of the bottom wall of the valve body 1, that is, the angle of each area occupied by the circumference of the bottom wall of the valve body 1 is 60 degrees. Each area is provided with a flow channel opening that passes through the bottom wall axially, and each flow channel opening is located on the same circumference. The flow channel openings of the first area 11a and the second area 11b are connected in the circumferential direction to form a first interface 11, the flow channel opening of the third area 12a forms a second interface 12, the flow channel opening of the fourth area 14a forms a fourth interface 14, and the flow channel openings of the fifth area 13a and the sixth area 13b are connected in the circumferential direction to form a third interface 13. The first interface 11, the second interface 12, the fourth interface 14 and the third interface 13 are arranged in sequence in a counterclockwise or clockwise direction. It can also be understood that there are six flow openings evenly distributed along the circumferential direction on the bottom wall of the valve body 1, two circumferentially adjacent flow openings are connected to form a first interface 11, and another two circumferentially adjacent flow openings are connected to form a third interface 13, and the first interface 11 and the third interface 13 are adjacent in the circumferential direction.

[0059] The first interface 11, the second interface 12, the fourth interface 14 and the third interface 13 are distributed in sequence along the circumference of the bottom wall of the valve body 1 (they can be arranged in sequence clockwise or counterclockwise), and the second interface 12 and the fourth interface 14 have the same size; the first interface 11 and the third interface 13 have the same size.

[0060] In the three adjacent and continuous areas along the circumferential direction of the bottom wall of the valve body 1, namely, the first area, the middle area, and the last area, when the valve core 9 rotates to the point where the first valve core flow channel 91 is directly opposite to the flow channel opening of the first area, the second valve core flow channel 92 is directly opposite to the flow channel opening of the last area, and the third valve core flow channel 93 bypasses the flow channel opening of the middle area, and the valve core flow channel connects the flow channel opening of the first area and the flow channel opening of the last area. It can also be understood that the valve core 9 can rotate at any angle in the inner cavity of the valve body 1. When the valve core 9 rotates to the point where the first valve core flow channel 91 is connected to the flow channel opening of the first area, the second valve core flow channel 92 is connected to the flow channel opening of the last area, and at this time, the third valve core flow channel 93 and the flow channel opening of the middle area have no overlapping parts in the axial projection, that is, the third valve core flow channel 93 is not connected to the flow channel opening of the middle area. The flow channel opening of the first area and the flow channel opening of the last area are connected through the first valve core flow channel 91 and the second valve core flow channel 92. When rotating to other angles, the first valve core flow channel 91 and the second valve core flow channel 92 are connected to other flow channel openings, thereby realizing the switching of different modes of the multi-way valve.

[0061] In this embodiment, a valve core flow channel is provided on the bottom end surface of the valve core 9, and the valve core flow channel includes a first valve core flow channel 91 and a second valve core flow channel 92 of the same structure and circumferentially spaced, and the first valve core flow channel 91 and the second valve core flow channel 92 are connected through a third valve core flow channel 93 provided on the bottom end surface. The bottom wall of the valve body 1 is divided into a first area 11a, a second area 11b, a third area 12a, a fourth area 14a, a fifth area 13a and a sixth area 13b in the circumferential direction, and each area is provided with a flow channel opening that passes through the bottom wall in the axial direction, and each flow channel opening is located on the same circumference. The flow channel openings of the first area 11a and the second area 11b are connected in the circumferential direction to form a first interface 11, and the flow channel openings of the third area 12a form a second interface 12; the flow channel openings of the fourth area 14a form a fourth interface 14, and the flow channel openings of the fifth area 13a and the sixth area 13b are connected in the circumferential direction to form a third interface 13. In this solution, the valve core 9 is rotated to any angle along its own axis in the inner cavity of the valve body 1. When the valve core 9 is rotated to the point where the first valve core flow channel 91 corresponds to the flow channel opening of the first area, the second valve core flow channel 92 corresponds to the flow channel opening of the last area, and the third valve core flow channel 93 bypasses the flow channel opening of the middle area. The flow channel opening of the first area and the flow channel opening of the last area are connected through the valve core flow channel. When rotating to other angles, the valve core flow channel is connected to other different flow channel openings, so that this embodiment can achieve switching of multiple modes through a simple structure, with better functionality, economy and topology.

[0062] In one embodiment, if Figure 3 and Figure 4As shown, the sizes of the first valve core flow channel 91 and the second valve core flow channel 92 are matched with the second interface 12, that is, the sizes of the first valve core flow channel 91 and the second valve core flow channel 92 are matched with the fourth interface 14, that is, the sizes of the first valve core flow channel 91 and the second valve core flow channel 92 are matched with each flow channel opening. Size matching includes the situations of being exactly the same size, slightly larger size or slightly smaller size, and the above situations are all within the protection scope of this embodiment.

[0063] In one embodiment, if Figure 4 As shown, the shapes and sizes of the flow channel openings are the same and are evenly distributed along the circumference of the bottom wall.

[0064] In one embodiment, if Figure 3 and Figure 4 As shown, the shapes of the first valve core flow channel 91 and the second valve core flow channel 92 match the flow channel openings respectively.

[0065] In one embodiment, if Figure 3 and Figure 4 As shown, the first valve core flow channel 91, the second valve core flow channel 92 and the flow channel opening are all in the shape of a sector.

[0066] In one embodiment, if Figure 4 As shown, there is a first circumferential interval D between the first interface 11 and the second interface 12 in the circumferential direction, and the radial dimensions of the first interface 11, the second interface 12, the third interface 13 and the fourth interface 14 are all the same. The circumferential dimension of the first interface 11 is equal to the sum of the circumferential dimensions of the second interface 12, the first circumferential interval D, and the fourth interface 14; the circumferential dimension of the third interface 13 is also equal to the sum of the circumferential dimensions of the second interface 12, the first circumferential interval D, and the fourth interface 14.

[0067] In one embodiment, if Figure 4 As shown, the first interface 11 and the second interface 12 , the second interface 12 and the fourth interface 14 , the fourth interface 14 and the third interface 13 , and the third interface 13 and the first interface 11 have the same circumferential spacing.

[0068] In one embodiment, a limit bearing is provided in the third valve core flow channel 93 of the valve core 9 .

[0069] In one embodiment, if Figure 3 As shown, the first valve core flow channel 91 and the second valve core flow channel 92 differ by 120° in the circumferential direction. The first interface 11, the second interface 12, the fourth interface 14 and the third interface 13 are also fan-shaped, and the length of the arc near the center of the bottom end surface of the valve core 9 is smaller than the length of the arc away from the center. This makes the shape of the valve core flow channel and the flow channel opening more matched, thereby increasing the liquid flow rate when connected.

[0070] In one embodiment, if Figure 6 As shown, radial spoilers 17 are arranged in the middle of the first interface 11 and the third interface 13 along the circumferential direction, wherein one spoiler 17 divides the top of the first interface 11 into two flow channel areas along the circumferential direction, and the other spoiler 17 divides the top of the third interface 13 into two flow channel areas along the circumferential direction. The spoilers 17 are arranged at the top of the first interface 11 and the third interface 13 along the axial direction, respectively, and the length of the spoiler 17 is less than the length of the first interface 11 and the third interface 13 along the axial direction, so it will not affect the connection between the two flow channel openings in the first interface 11 and the third interface 13. The spoiler 17 plays a role of spoiling the flow and reducing the flow resistance.

[0071] In one embodiment, the spoiler 17 has an inner end facing the inner cavity of the valve body 1 and a corresponding outer end, the end of the spoiler 17 facing the inner cavity of the valve body 1 is the inner end, and the end away from the valve body 1 is the outer end. The two sides of the spoiler 17 along the circumferential direction are inclined surfaces whose height gradually increases from the outer end to the inner end, that is, the two sides of the spoiler 17 along the circumferential direction are inclined surfaces, and the height of the inclined surfaces gradually decreases in the direction away from the valve core 9, that is, the outer end of the spoiler 17 is wedge-shaped. The inner end surface of the spoiler 17 is a smooth cambered surface. Further, it plays a role in disturbing flow and reducing flow resistance. When the fluid enters from the top of the first interface 11 and the third interface 13, it plays a role in disturbing flow and reducing flow resistance through the effect of the inclined surface of the spoiler 17.

[0072] In one embodiment, if Figure 3 As shown, the third valve core flow channel 93 passes through the center of the bottom end surface of the valve core 9, so that the distance between the first valve core flow channel 91 and the second valve core flow channel 92 is the shortest, thereby shortening the time required for the fluid to pass through the valve core channel and improving the flow efficiency of the fluid in the multi-way valve.

[0073] In one embodiment, if Figure 3 As shown, a blocking area is formed between the first valve core flow channel 91 and the second valve core flow channel 92 along the circumferential direction. When the flow channel opening of the first area and the flow channel opening of the last area in the three continuous areas on the bottom wall of the valve body 1 are connected through the valve core flow channel, the blocking area covers the flow channel opening in the middle area, that is, the blocking area can block the flow channel opening in the middle area, thereby preventing the flow channel opening in the middle area from being connected to the valve core channel and causing multiple mode failures of the multi-way valve.

[0074] In one embodiment, if Figure 1As shown, a first sealing member 16 is provided between the bottom wall of the valve body 1 and the valve core 9, and a second sealing member 15 is provided on the outer bottom of the valve body 1. Both the first sealing member 16 and the second sealing member 15 include but are not limited to sealing rings. Both the first sealing member 16 and the second sealing member 15 are provided with sealing through holes matching the respective flow passage openings. The first sealing member 16 is used to seal between the bottom wall of the valve body 1 and the bottom end surface of the valve core 9, and the second sealing member 15 is used to seal between the bottom wall of the valve body 1 and an external device.

[0075] In one embodiment, a first sealing groove is provided on the bottom wall of the valve body 1, and a first sealing member 16 is provided in the first sealing groove. A second sealing groove is provided on the outer bottom of the valve body 1, and a second sealing member 15 is provided in the second sealing groove. The provision of the first sealing groove and the second sealing groove can prevent the first sealing member 16 and the second sealing member 15 from collapsing in the radial direction of the valve body 1.

[0076] In one embodiment, if Figure 1 As shown, the multi-way valve further includes a valve cover 3 and an actuator 8. The valve cover 3 is arranged on the inner cavity opening of the valve body 1 and can close the inner cavity of the valve body 1. The actuator 8 is arranged on the top of the valve cover 3. The output end of the actuator 8 is transmission-connected with the valve core 9. The actuator 8 is used to drive the valve core 9 to rotate along its own axis. The actuator 8 can be electrically connected to the thermal management system to perform different actions.

[0077] Specifically, the actuator 8 may include a motor and a transmission assembly. The motor may be a stepping motor, and the transmission assembly may be a gear set. The output end of the motor may be connected to an input gear in the gear set, and the output gear in the gear set may be transmission-connected to the valve core 9.

[0078] In one embodiment, if Figure 1 As shown, the multi-way valve further includes an adapter block 6 and a friction reduction ring 5. The adapter block 6 is located between the valve cover 3 and the valve core 9, and the friction reduction ring 5 is located between the valve cover 3 and the adapter block 6. The valve cover 3 can drive the valve core 9 to rotate through the adapter block 6, so that the valve core 9 can be rotatably arranged in the inner cavity of the valve body 1. The friction reduction ring 5 can be installed in the inner groove opened on the top surface of the adapter block 6, and the shape of the friction reduction ring 5 can be adapted to the shape of the inner groove. The friction reduction ring 5 can be used to prevent the adapter block 6 from directly contacting and rubbing with the valve cover 3, so as to protect the structure of the adapter block 6.

[0079] In one embodiment, if Figure 1 and Figure 5As shown, an elastic member 7 is provided between the valve core 9 and the adapter block 6, and the adapter block 6 presses the elastic member 7 against the valve core 9. The elastic member 7 includes a spring, preferably a wave spring.
