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 opening groove, so that the second inlet port can be communicated with the second outlet port;

the fourth port is disposed above the first port, and the fourth port is adjacent to the second open groove, so that the second inlet port can communicate 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 in communication with the first open slot such that the first inlet port may be in communication with the first outlet port, a projection of the third open slot having one end falling within a projection of the first open slot and another end outside the projection of the first open slot;

14. The electronic water valve of claim 13, wherein the first and second disks are each provided with ribs.

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 having through holes corresponding to 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 one-to-one, and sealing ribs disposed around the through holes.

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

17. The electronic water valve of claim 16, wherein the sealing gasket includes an elastically deformable layer and a low friction layer, the elastically deformable layer being attached to a periphery of the low friction layer.

18. The e-water valve of claim 17, further comprising a valve cover mounted over the valve housing, the valve cover having a mounting aperture for connection to the drive mechanism, and a drive mechanism.

19. A thermal management system comprising an electronic water valve as claimed in any of claims 1 to 18.

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