In order to improve the driving range, new energy vehicles have increasingly more requirements for vehicle thermal management design. From the perspectives of cost saving, weight reduction, and space utilization, it is more important to integrate multiple on / off valves into a smaller number of multi-functional water valves.

[0004] In view of this, it is necessary to improve the existing multi-mode four-way valve to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figures 1 to 3 As shown, the thermal management module of this utility model includes at least one multi-mode four-way valve 100.

[0032] The multi-mode four-way valve 100 includes a valve body 1, a valve core 2 disposed within the valve body 1, a valve cover 3 disposed on one side of the valve body 1 to cover the valve core 2, an actuator 4 connected to the valve core 2, and a top cover 5 disposed between the actuator 4 and the valve core 2.

[0033] The valve body 1 includes a side wall 11, which surrounds the valve core 2. The valve cover 3 is disposed at one end of the side wall 11. In this embodiment, the valve cover 3 is integrally formed with the side wall 11.

[0034] The actuator 4 is used to drive the valve core 2 to rotate relative to the valve cover 3. The valve core 2 is disposed inside the valve body 1 and located between the valve cover 3 and the top cover 5. Preferably, a wear-resistant plate 6 is provided between the top cover 5 and the valve core 2. In this embodiment, the top cover 5 and the side wall 11 are fixedly connected by screws, but it is not limited to this. In other embodiments, they can also be connected by bolts, welding, etc.

[0035] The valve core 2 has a first flow channel 21 and a second flow channel 22 with openings facing the valve cover 3, a baffle 23 separating the first flow channel 21 and the second flow channel 22, a baffle 24 separating the first flow channel 21 and the second flow channel 22, and a support plate 25 protruding towards the valve cover 3.

[0036] The baffle 24 is disposed on the side away from the block 23. The block 23 is located between the first flow channel 21 and the second flow channel 22, and the baffle 24 is located between the first flow channel 21 and the second flow channel 22.

[0037] The abutment plate 25 is arranged in a circle and coaxially with the valve core 2. The baffle 24 and the stop block 23 are both connected to the abutment plate 25, and the baffle 24 and the stop block 23 are respectively arranged on opposite sides of the abutment plate 25. Furthermore, in this embodiment, one side of the baffle 24 and the stop block 23 are directly opposite each other.

[0038] In this embodiment, the first flow channel 21 and the second flow channel 22 are both formed by the baffle 24, the stop block 23, the abutment plate 25 and the side wall 11 of the valve core 2.

[0039] A rotating shaft 26 is provided in the middle of the valve core 2. One end of the rotating shaft 26 is connected to the actuator 4 to drive the valve core 2 to rotate. The valve cover 3 has a limiting part 35 facing the valve core 2, and the other end of the rotating shaft 26 is inserted into the limiting part 35. The rotating shaft 26 passes through the top cover 5, and a sealing ring is provided between the rotating shaft 26 and the top cover 5.

[0040] The length of the first flow channel 21 is longer than the length of the second flow channel 22. The length is defined as the length extending circumferentially along the inner wall of the valve core; that is, the circumferential length of the inner wall of the valve core forming the sidewall of the first flow channel 21 is greater than the circumferential length of the inner wall of the valve core forming the sidewall of the second flow channel 22. When the stop block 23 blocks the flow channel opening 31, the first flow channel 21 connects to both flow channel openings 31. When the stop block 23 does not block the flow channel opening 31, the first flow channel 21 and the second flow channel 22 respectively connect to the two flow channel openings 31.

[0041] Both the first flow channel 21 and the second flow channel 22 are fan-shaped, with the first flow channel 21 having an angle of 180 degrees and the second flow channel 22 having an angle of 135 degrees. The baffle 23 is also fan-shaped with an angle of 45 degrees. It should be noted that due to the presence of the baffle 24 and the existence of process errors, the above-mentioned angular deviation of a few degrees can achieve the same effect without affecting the use.

[0042] The valve cover 3 is provided with a plurality of flow ports 31 for communicating with the first flow channel 21 and the second flow channel 22. In this embodiment, the number of flow ports 31 is four. The valve core 2 is rotatably disposed relative to the valve cover 3. The stop block 23 can block one flow port 31. The first flow channel 21 and the second flow channel 22 can both communicate with two flow ports 31.

[0043] The flow channels 31 are arranged in a circumferential array. In this embodiment, the valve cover 3 is further provided with a blocking portion 32 located between two adjacent flow channels 31, and the number of blocking portions 32 is four. In this embodiment, each flow channel 31 and each blocking portion 32 is fan-shaped and equal in size. The angle between the flow channel 31 and the blocking portion 32 is approximately 45 degrees.

[0044] The valve cover 3 is provided with an inner sealing gasket 33 on the side facing the valve core 2, and an outer sealing gasket 34 on the side facing away from the valve core 2. Both the inner sealing gasket 33 and the outer sealing gasket 34 are arranged around the shielding part 32 and the flow channel 31.

[0045] The number of flow ports 31 is four, namely flow port 311, flow port 312, flow port 313, and flow port 314. The multi-mode four-way valve 100 has eight operating modes:

[0046] First working mode: The block 23 blocks the third flow channel opening 313, and the first flow channel opening 311 and the second flow channel opening 312 are connected through the first flow channel 21;

[0047] Second working mode: The second flow channel 312 and the third flow channel 313 are connected through the first flow channel 21, and the first flow channel 311 and the fourth flow channel 314 are connected through the second flow channel 22;

[0048] Third working mode: The block 23 blocks the fourth flow channel opening 314, and the second flow channel opening 312 and the third flow channel opening 313 are connected through the first flow channel 21;

[0049] Fourth working mode: The third flow channel port 313 and the fourth flow channel port 314 are connected through the first flow channel 21, and the first flow channel port 311 and the second flow channel port 312 are connected through the second flow channel 22;

[0050] Fifth working mode: The block 23 blocks the first flow channel opening 311, and the third flow channel opening 313 and the fourth flow channel opening 314 are connected through the first flow channel 21;

[0051] Sixth working mode: The first flow channel 311 and the fourth flow channel 314 are connected through the first flow channel 21, and the second flow channel 312 and the third flow channel 313 are connected through the second flow channel 22;

[0052] Seventh working mode: The block 23 blocks the second flow channel opening 312, and the first flow channel opening 311 and the fourth flow channel opening 314 are connected through the first flow channel 21;

[0053] Eighth working mode: The first flow channel 311 and the second flow channel 312 are connected through the first flow channel 21, and the third flow channel 313 and the fourth flow channel 314 are connected through the second flow channel 22.

[0054] The multi-mode four-way valve 100 and thermal management module of this utility model can achieve multi-mode flow by setting a baffle 23 to block or retain a flow port 31. It occupies a small volume, has high space utilization, and can realize more working modes of thermal management system.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
