The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 6, the thermal management module of the present invention includes one or more electronic valves 100, where the number of the electronic valves 100 is one or more.

The electronic valve 100 comprises a valve body 1, a valve core 2 rotatably arranged in the valve body 1, a sealing gasket 3, a valve cover 4 arranged at one end of the valve core 2, a transmission shaft 5 connected with the valve core 2 and used for driving the valve core 2 to rotate, and a sealing element 6 arranged between the valve core 2 and the valve body 1.

The valve core 2 is provided with a partition plate 21 for separating at least two flow passages 22, the partition plate 21 is used for separating at least two flow passages 22, and the middle part of the valve core 2 is provided with a positioning shaft 23 which is coaxial with the axis of the valve core 2. The openings of at least two of the flow passages 22 are disposed toward the valve cover 4.

The valve cover 4 is used for limiting the position of the valve core 2 along the axial direction. The valve cover 4 is provided with at least two flow passage ports 41 for communicating with the flow passage 22, a connecting portion 42 for separating the at least two flow passage ports 41, a surrounding portion 43 surrounding the connecting portion 42, and a positioning hole 44.

The positioning hole 44 is disposed in the middle of the valve cap 4 and cooperates with the positioning shaft 23 to define the position of the valve cap 4 relative to the valve core 2.

One end of the valve cover 4 facing the valve core 2 is recessed inwards to form a containing part 45, and the sealing gasket 3 is arranged in the containing part 45. Further, the receiving portion 45 includes a first receiving portion 451 positioned in the surrounding portion 43 and a second receiving portion 452 positioned in the connecting portion 42.

The seal 6 is arranged around the drive shaft 5. Specifically, one end of the valve element 2, which is far away from the valve cover 4, protrudes outwards to form a transmission part 24 to be connected with the transmission shaft 5 through a pin key, one end of the valve body 1, which is far away from the valve cover 4, protrudes towards the valve cover 4 to form a limiting part 11, the limiting part 11 surrounds the transmission part 24, and the valve element 2 is arranged between the limiting part 11 and the transmission part 24.

The transmission shaft 5 is provided with a first limiting block 51 at one end protruding out of the valve body 1, a second limiting block 12 is arranged at one end, far away from the valve cover 4, of the valve body 1, and the second limiting block 12 is used for abutting against the first limiting block 51 and limiting the rotation angle of the transmission shaft 5.

As shown in fig. 2 and 6, the gasket 3 includes a first sealing portion 31 formed in an annular shape, and a second sealing portion 32 disposed inside the first sealing portion 31 and connected to the first sealing portion 31, and the first sealing portion 31 and the second sealing portion 32 are recessed inward in a radial direction to form a C-shaped surface 33. The C-shaped surface 33 makes the gasket 3 more easily deformed, and when the internal pressure of the valve element 2 rises, the fluid presses the C-shaped surface 33 of the gasket 3 to increase the pressure between the gasket 3 and the valve body 1 and between the gasket 3 and the valve element 2, thereby increasing the sealing effect.

The partition 21 abuts against the first sealing portion 31, thereby separating at least two flow passages 22.

The C-shaped surface 33 in this embodiment is not required to be completely symmetrical up and down, as long as the central portion is recessed inward to a depth greater than up and down.

The number of the second sealing portions 32 is two, and the two second sealing portions 32 are cross-shaped and pass through the axis of the first sealing portion 31.

The number of the connecting parts 42 is more than or equal to that of the partition boards 21, and the connecting parts 42 and the partition boards 21 are arranged in a rotational symmetry manner. This allows the first seal 6 in the connecting portion 42 to be held against each rotation of the valve element 2 through a certain angle.

In this embodiment, the number of the partition plates 21 is one, the number of the flow passages 22 is two, one partition plate 21 extends in the radial direction through the axis of the valve element 2, the number of the connection portions 42 is two, the number of the flow passage openings 41 is four, and the two connection portions 42 are arranged in a cross shape and pass through the axis of the valve element 2.

The first seal portion 31 is provided in the first receiving portion 451, and the second seal portion 32 is provided in the second receiving portion 452.

A plurality of mounting protrusions 34 protruding outwards in the radial direction are arranged in the C-shaped surface 33, and the mounting protrusions 34 are in interference fit with the valve cover 4 to fix the sealing gasket 3 better.

After the valve core 2 is installed in the valve body 1, the axial end face of the valve core 2 does not exceed the end face of the valve body 1.

In addition, because the sealing gasket 3 and the valve body 1 are static sealing, and the sealing gasket 3 and the valve core 2 are dynamic sealing, after the whole electronic valve 100 is installed, the height of the side wall of the valve body 1 is higher than that of the valve core 2, so that the pressure between the valve body 1 and the sealing gasket 3 is higher than that between the valve core 2 and the sealing gasket 3, and the torque of the valve core 2 is reduced while the sealing performance of the whole valve is ensured.

The utility model discloses a heat treatment module, electronic valve 100 and sealed 3 of filling up establishes to inside sunken C profile 33 through the radial surface that will seal up 3 for the pressure between sealed 3 and the case 2 of filling up reduces, and little with case 2 area of contact, thereby the moment of torsion of case 2 has been reduced, when case 2 internal pressure risees, the fluid can extrude the C profile 33 of sealed 3 of filling up, with the pressure of increasing sealed 3 and valve body 1 and sealed 3 and the case 2 of filling up, thereby increase sealed effect.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
