11. The electronic water valve of claim 10, wherein a central angle of the first port is greater than a central angle of the first open slot, the first port being provided with a stiffening rib.

12. The electronic water valve of claim 11, wherein the second open slot is disposed above and in communication with the first open slot such that the first inlet port can communicate with either the fourth outlet port or the second outlet port, the first open slot projecting beyond the second open slot projecting ends;

the second port is arranged above the first port, and a space is reserved between the second port and the fourth port and between the second port and the second open groove respectively, so that the second inlet port can be communicated with the second outlet port;

the fourth port is arranged above the first port and is adjacent to the second open groove, so that the second inlet port can be communicated with the fourth outlet port; the central angle of the fourth port is the same as the central angle of the second port.

13. The electronic water valve of claim 12, wherein the third open slot is disposed below the first open slot and communicates with the first open slot such that the first inlet port can communicate with the first outlet port, a projected end of the third open slot falling within the first open slot projection and the other end being outside of the first open slot projection;

The third port is arranged below the first port, is adjacent to the third open groove and is spaced from the fifth port, so that the second inlet port can be communicated with the first outlet port, and the projection two ends of the first port are beyond the projection two ends of the third port;

the fifth port is arranged below the first port and is communicated with the first port, so that the second inlet port can be communicated with the third outlet port, and the projection two ends of the first port are beyond the projection two ends of the fifth port; and the central angle of the fifth port is larger than that of the third port.

14. The electronic water valve of claim 13, wherein the first and second turntables are each provided with a bead.

15. The electronic water valve of claim 14, further comprising a sealing gasket mounted between the valve housing and the valve core, the sealing gasket being provided with through holes in one-to-one correspondence with the first inlet port, the second inlet port, the first outlet port, the second outlet port, the third outlet port, and the fourth outlet port, and sealing ribs being provided around the through holes.

16. The electronic water valve of claim 15, wherein the sealing bead is serrated.

17. The electronic water valve of claim 16, wherein the gasket comprises an elastically deformable layer and a low friction layer, the elastically deformable layer conforming to the periphery of the low friction layer.

18. The electronic water valve of claim 17, further comprising a valve cover and a drive device, the valve cover being mounted above the valve housing, the valve cover being provided with a mounting hole for connecting the drive device.

19. A thermal management system comprising the electronic water valve of claims 1-18.

20. A vehicle comprising the thermal management system of claim 19.
