[0053] The dynamic sealing structure of the utility model is a new type of dynamic sealing structure of a thermal management module applied to a thermal management module based on an electronically controlled actuator. Figures 1 to 3 As shown, the utility model provides a dynamic sealing structure of a thermal management module, which includes a housing 1, a dynamic sealing module 2, a metal ring 3, a Y-shaped sealing ring 4, a ball valve sealing ring 5 and a ball valve 6.

The utility model adds a metal ring and a Y-shaped sealing ring structure at the opening of the housing 1, installs the ball valve sealing ring, the metal ring, the Y-shaped sealing ring, the dynamic sealing module, etc. into the housing, and forms a plurality of sealing structures to work together by sealing between the metal ring and the housing, between the Y-shaped sealing ring and the housing, between the dynamic sealing module and the housing, and between the metal ring, the Y-shaped sealing ring, the ball valve sealing ring and the dynamic sealing module, thereby playing a role in strengthening the seal, and overcoming the defects and wear defects of the sediment impurities, aluminum filings, iron filings and other pollutants in the cooling water in the prior art conditions that will enter the dynamic sealing structure, resulting in the dynamic sealing structure being stuck and failing. In addition, the Y-shaped sealing ring and the metal ring are used in combination, and the Y-shaped sealing ring has a radial interference fit with the housing and the ball valve sealing ring at the same time, and the metal ring has a radial interference fit with the housing and the Y-shaped sealing ring at the same time. The interference fit can effectively prevent the sediment impurities and other pollutants in the cooling water from entering the inner wall area of ​​the housing, resulting in the failure of the dynamic sealing structure function.

[0054] See also Figure 3 The channel 10 includes a first channel 11, a second channel 12 and a third channel 13 arranged in sequence, and the third channel 13 is adjacent to the opening 101. In the present invention, the inner diameters of the first channel, the second channel and the third channel increase in sequence. By setting a plurality of stepped channels, each channel can be sealed, thereby improving the sealing effect. Figures 1 to 3 As shown, in a preferred embodiment, the dynamic sealing module 2 is interference-connected to the inner wall of the first channel 11, thereby performing radial limiting and sealing, which can prevent impurities and contaminants in the cooling water from entering the dynamic sealing module. The ball valve sealing ring 5 passes through the second channel 12 and the third channel 13 from the first channel 11 to the opening 101. The Y-type sealing ring 4 is interference-connected to the inner wall of the second channel 12, the Y-type sealing ring 4 extends from the second channel 12 to the third channel 13, and the Y-type sealing ring 4 is interference-connected to the outer ring of the ball valve sealing ring 5. The metal ring 3 is interference-connected to the inner wall of the third channel 13, and the metal ring 3 is interference-sleeved on the outer ring of the Y-type sealing ring 4. The utility model forms an interference fit between the metal ring 3 and the Y-shaped sealing ring 4 and the inner wall of the channel to achieve a sealing effect, forms an interference fit between the Y-shaped sealing ring 4 and the inner wall of the channel and the ball valve sealing ring 5 to achieve a sealing effect, and forms a radial interference fit between the dynamic sealing module 2 and the inner wall of the channel to achieve a sealing effect. The sealing structures at these locations work together to improve the sealing performance of the dynamic sealing structure, and can effectively prevent impurities and contaminants in the cooling water from entering the dynamic sealing module to cause product jamming and wear of parts.

[0055] See also Figure 4 , the dynamic sealing module 2 is a cylindrical structure, and the dynamic sealing module is a module that can still play a sealing role in a dynamic working state. Specifically, the outer ring of the dynamic sealing module 2 has a protruding structure 21, and the protruding structure 21 is interference-connected with the axial inner wall 111 of the first channel to prevent the radial movement of the dynamic sealing module 2 and play a sealing role in the working process of the product. When the dynamic sealing module 2 is squeezed, the protruding structure 21 of the dynamic sealing module 2 squeezes the axial inner wall 111 of the first channel and plays a sealing role with the first axial inner wall 111. At the same time, the dynamic sealing module 2 is compressed in the channel and moves along the axial inner wall 111 of the first channel. At this time, the radial inner wall 112 of the first channel will block the axial movement of the dynamic sealing module 2, thereby also playing a sealing role on the dynamic sealing module 2 and the radial inner wall 112 of the first channel. In another embodiment, the protruding structure 21 has an installation bevel 211, and the installation bevel 211 is to prevent the sealing ring of the dynamic sealing module 2 from flipping during assembly.

[0056] Please continue reading Figure 7, the ball valve seal ring 5 has a ball valve seal ring outer ring 51 and a ball valve seal ring inner ring. The ball valve seal ring outer ring 51 is a plane structure. The ball valve seal ring inner ring has an inner ring upper plane 53, an inner ring lower plane 54 and an inclined surface 52. The inclined surface 52 is located at the opening 101. The ball valve 6 is sealed against the inclined surface 52, and the inclined surface 52 is in contact with the ball valve structure 61. The ball valve plays a sealing role during the rotation process, and the liquid does not leak at this seal. In the utility model, a part of the ball valve seal ring outer ring 51 moves axially along the axial inner wall 111 of the first channel, so that the length of the axial matching straight line section between the housing 1 and the ball valve seal ring 5 is shortened, which can reduce the accumulation of impurities in the cooling water between the housing and the ball valve seal ring 5, resulting in jamming and wear. At the same time, the ball valve seal ring 5 and the Y-type seal ring 4 are interference-fitted to prevent impurities and pollutants in the cooling water from entering the dynamic sealing structure.

[0057] The dynamic sealing module 2 further includes a cylindrical sealing ring 20 and a reinforced sealing ring 22, wherein the reinforced sealing ring 22 is arranged on the outer ring of the cylindrical sealing ring 20. The reinforced sealing ring 22 is close to the center of the outer ring of the cylindrical sealing ring 20, and the protruding structure 21 is arranged on the reinforced sealing ring 22. Along the axial direction of the channel, the upper plane 53 of the inner ring of the ball valve sealing ring 5 is sealed against the outer ring of the cylindrical sealing ring 20, and the inner ring of the cylindrical sealing ring 20 is flush with the lower plane 54 of the inner ring of the ball valve sealing ring 5, thereby improving the sealing performance.

[0058] Please continue reading Figures 1 to 6The Y-shaped sealing ring 4 has an outer surface 41, an upper surface 42 and an inner bevel 44. The outer surface 41 is in interference connection with the axial inner wall 121 of the second channel. The outer surface 41 is formed with a slot 43. The slot 43 has an axial slot surface 431 and a radial slot surface 432. The metal ring 3 is in interference contact with the slot 43. The upper surface 42 is in interference connection with the radial inner wall 122 of the second channel. Along the axial direction of the channel, from the inside of the channel to the opening direction, the inner bevel 44 extends obliquely toward the channel axis. The inner bevel 44 is partially in interference connection with the outer ring 51 of the ball valve sealing ring. The utility model can not only realize the sealing effect of the inner ring of the ball valve seal ring 5 and the inner ring of the Y-type seal ring by setting the inner ring of the Y-type seal ring 4 as an inclined surface, but also form a containing space between the inner inclined surface 44 of the inner ring of the Y-type seal ring that is not in contact with the ball valve seal ring and the ball valve seal ring when the ball valve seal ring 5 and the Y-type seal ring are squeezed, so as to accommodate the ball valve seal ring 5 and the Y-type seal ring 4 that are deformed due to squeezing, thereby extending the service life of the ball valve seal ring and the Y-type seal ring. In another embodiment, the Y-type seal ring also has an outer inclined surface 45, which extends obliquely in the direction of the channel axis from the inside of the channel 10 to the opening 101. By increasing the outer inclined surface 45, the thickness between the inner inclined surface 44 and the outer inclined surface 45 is reduced. When the inner inclined surface 44 of the Y-type seal ring 4 is deformed by force, the inner inclined surface 44 and the outer inclined surface 45 are more likely to deform to release the squeezing force on the inner inclined surface, which can extend the service life of the Y-type seal ring. The outer slope 45 faces the opening 101 for easy observation and replacement.

[0059] Please continue reading Figure 5 The metal ring 3 has an outer ring 31, an inner ring 33, an upper ring 32 and a lower ring 34. The outer ring 31 is in interference connection with the axial inner wall 131 of the third channel, and is radially limited to prevent the metal ring 3 from moving. The inner ring 33 of the metal ring 3 is in interference connection with the axial surface 431 of the card slot of the Y-shaped sealing ring 4, and part of the upper ring 32 of the metal ring is in interference connection with the radial surface 432 of the card slot, and the metal ring is axially and radially interference connected in the card slot 43. The metal ring is axially and radially limited by the card slot, which further plays a sealing role, and can prevent impurities and contaminants in the cooling water from entering the dynamic sealing structure to cause jamming and wear; at the same time, another part of the upper ring 32 is in interference connection with the radial inner wall 132 of the third channel, so as to axially limit the metal ring, and the lower ring 34 faces the outside of the opening, which is convenient for replacement.

[0060] See also Figure 8 The ball valve 6 is a plastic ball valve having a spherical surface structure 61, and the spherical surface structure 61 is in sealing contact with the inclined surface 52. The ball valve 6 is a double ball valve or a single ball valve. During the rotation of the ball valve, the spherical surface structure of the ball valve cooperates with the inclined surface of the ball valve sealing ring to seal, and the liquid does not leak at this sealing point.

[0061] like Figure 1 As shown, when the ball valve 6 rotates to the flow port (not shown) on the ball valve and connects with the channel 10 of the housing 1, the dynamic sealing structure is in an open state. At this time, the ball valve 6 pushes the ball valve sealing ring 5 into the channel 10 of the housing 1. The ball valve sealing ring 5 and the dynamic sealing module 2 are deformed due to force compression. A part of the outer ring 51 of the ball valve sealing ring is tightly attached to the axial inner wall 111 of the first channel and moves upward. The dynamic sealing module 2 is also squeezed and then sealed with the axial inner wall 111 of the first channel and the radial inner wall 112 of the first channel. In this way, the gap between the dynamic sealing module 2 and the inner wall of the channel, the gap between the ball valve sealing ring 5 and the inner wall of the channel are closed. The gap between them is reduced or disappears, thereby preventing impurities in the fluid in the channel from accumulating between the dynamic sealing module and the housing and between the ball valve sealing ring and the housing. At the same time, the ball valve sealing ring 5 and the dynamic sealing module 2, the Y-shaped sealing ring 4 and the inner wall of the channel, the Y-shaped sealing ring 4 and the ball valve sealing ring 5, the metal ring 3 and the inner wall of the channel, and the metal ring 3 and the Y-shaped sealing ring 4 are all in a sealed state, thereby effectively preventing pollutants such as mud, aluminum filings, and iron filings in the cooling water flowing through the channel from entering the dynamic sealing result, thereby causing defects such as the dynamic sealing structure being stuck and failing, and impurities entering the dynamic sealing structure causing parts wear.

[0062] like Figure 2 As shown, when the ball valve 6 rotates to close the channel 10 of the shell 1, the dynamic sealing structure is in a closed state, and the elastic force of the dynamic sealing module 2 and the ball valve sealing ring 5 is restored. Because the dynamic sealing module 2 is interfered with the inner wall 111 of the first axial channel, the Y-shaped sealing ring is interfered with the inner wall of the channel, the Y-shaped sealing ring is interfered with the ball valve sealing ring, the metal ring is interfered with the inner wall of the channel, and the metal ring is interfered with the Y-shaped sealing ring. The contaminants such as mud, aluminum filings, and iron filings in the cooling water in the channel can still be effectively prevented from entering the dynamic sealing structure.

[0063] The utility model also provides a thermal management module, and the thermal management module comprises the above-mentioned dynamic sealing structure.

[0064] The dynamic sealing structure of the thermal management module of the utility model retains the original dynamic sealing structure that can have a good sealing effect under high and low pressures, and adds a metal ring and a Y-shaped sealing ring. Through the joint sealing effect of the metal ring and the housing, the metal ring and the Y-shaped sealing ring, the Y-shaped sealing ring and the housing, and the Y-shaped sealing ring and the ball valve sealing ring, the sealing effect is further improved, and it can effectively prevent the sediment impurities, aluminum filings, iron filings and other pollutants in the cooling water from entering the dynamic sealing module, the dynamic sealing module from getting stuck and failing, and impurities from entering the dynamic sealing structure to cause parts wear and other defects. The dynamic sealing structure of the thermal management module of the utility model, its housing, dynamic sealing module, ball valve sealing ring, metal ring, Y-shaped sealing ring, ball valve, can be connected together through interference fit, the overall structure is simple, production is convenient, the output is high, and the cost is low.
