[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] One application scenario of the valve device 1 or thermal management device 2 of the present invention is an on-vehicle thermal management system, where the valve component 11 controls fluid movement in the thermal management system;

[0040] First, in vehicle-mounted applications, since increased vehicle weight leads to increased fuel consumption, it is necessary to reduce the mass of the valve device 1 or the thermal management device 2. In the present application, the valve seat 111 in the valve component 11 is formed by stamping, which is beneficial to reducing the mass of the valve seat 111 compared to the valve seat 111 formed by machining. The valve seat 111 is located in the accommodating cavity 120, and the side walls of the accommodating cavity 120 can support the side of the valve seat 111, thereby improving the pressure-bearing capacity of the valve seat 111.

[0041] Second: In the prior art, during the assembly of the valve device 1, the valve component 11 is threadedly connected to the wall forming the accommodating cavity 120 through internal and external threads, and the valve body 12 or the valve component 11 is fastened to the coil assembly 13 by bolts. The assembly process is relatively cumbersome. In the present application, the valve component 11 can be inserted into the accommodating cavity 120 without hindrance, and then the coil assembly 13 and the valve body 12 are fixed or limited to realize the assembly of the valve device 1, which is conducive to simplifying the assembly steps and improving the assembly efficiency of the valve device 1.

[0042] Combine Figures 1 to 9 , Figures 11 to 15A valve device 1 includes a valve component 11, a valve body 12, and a coil assembly 13. The valve body 12 has a receiving cavity 120, and the coil assembly 13 has a sensing cavity 130. Part of the valve component 11 is located in the receiving cavity 120, and part of the valve component 11 is located in the sensing cavity 130. From the inside of the receiving cavity 120 to the direction of the opening of the receiving cavity 120 for the valve component 11 to enter, the inner diameter of the wall forming the receiving cavity 120 increases or remains substantially unchanged, and the valve component 11 is axially pressed against the wall forming the receiving cavity 120. Between the wall and the coil assembly 13, the coil assembly 13 is fixedly connected to the valve body 12, or the coil assembly 13 is axially limitedly connected to the valve body 12, and along the axial direction of the valve component 11, the valve component 11 is axially pressed between the coil assembly 13 and the valve body 12; with this arrangement, the valve component 11 is axially abutted against the valve body 12, and after the coil assembly 13 is axially abutted against the valve component 11, the assembly of the valve device 1 can be completed by fixing or limiting the connection of the coil assembly 13 and the valve body 12, which is beneficial to reducing the assembly steps of the valve device 1.

[0043] Combine Figures 2 to 7 The valve device 1 also includes a first sealing ring 15 and a second sealing ring 16. The first sealing ring 15 is sealingly arranged between the outer wall of the valve component 11 and the wall forming the accommodating chamber 120, and the second sealing ring 16 is sealingly arranged between the outer wall of the valve component 11 and the wall forming the accommodating chamber 120. The valve component 11 has a first port 1111, a second port 1112 and a valve port 1113. The first port 1111 is communicated with the valve chamber 1110, and the valve port 1113 is communicated with the second port 1112. The valve port 1113 can be communicated with the valve chamber 1110. The valve body 12 has a first channel 124 and a second channel 125. The first port 1111 is communicated with the first channel 124, and the second port 1112 is communicated with the second channel 125. Along the axial direction of the valve device 1, the first sealing ring 15 is sealingly arranged between the first port 1111 and the opening of the accommodating chamber 120 for inserting the valve component 11, and the second sealing ring 16 is sealingly arranged between the first port 1111 and the second port 1112.

[0044] Combine Figures 2 to 7 The valve component 11 includes a limit member 112, and the first sealing ring 15 is axially limited between the limit member 112 and the wall forming the accommodating chamber 120; specifically, the accommodating chamber 120 includes a fluid chamber 1201 and a mounting groove 1200, the inner diameter of the wall forming the mounting groove 1200 is larger than the inner diameter of the wall forming the fluid chamber 1201, and at least part of the step wall between the fluid chamber 1201 and the mounting groove 1200 forms a limit wall 122; along the axial direction of the valve component 11, the first sealing ring 15 is axially limited between the limit member 112 and the limit wall 122; with this arrangement, the limit member 112 can limit the first sealing ring 15 from being squeezed out due to excessive pressure of the fluid medium inside the accommodating chamber 120, which helps to reduce the risk of leakage of the valve device 1.

[0045] Furthermore, the outer diameter of the limit member 112 is larger than the outer diameter of the valve seat 111, and the limit member 112 is axially abutted against the support portion 121; with this arrangement, the limit member 112, which has a larger diameter than the valve seat 111, can disperse the pressure between the valve component 11 and the support portion 121, which helps to reduce the risk of damage to the valve seat 111 or the limit member 112 due to excessive bearing pressure.

[0046] Combine Figures 2 to 7 Furthermore, along the axial direction of the valve component 11, the inner diameter of the wall forming the mounting groove 1200 is reduced from the mounting groove 1200 to the direction of the fluid cavity 1201; along the axial direction of the valve component 11, the first sealing ring 15 is axially pressed between the limit member 112 and the side wall forming the mounting groove 1200; in this way, the first sealing ring 15 is axially sealed and arranged between the outer wall of the valve component 11 and the wall forming the accommodating cavity 120. Compared with the technical solution in which the first sealing ring 15 is radially sealed and arranged between the outer wall of the valve component 11 and the wall forming the accommodating cavity 120, this solution can reduce the installation resistance between the valve component 11 and the wall forming the accommodating cavity 120 during the assembly of the valve device 1, and reduce the risk of the first sealing ring 15 twisting during the assembly of the valve device 1 and causing leakage.

[0047] Combine Figure 4 and Figure 6 The valve component 11 includes a valve seat 111, an iron core assembly 113, a sleeve 114 and a valve core assembly 115. At least part of the iron core assembly 113 is located in the sleeve 114, and at least part of the valve seat 111 is located in the accommodating cavity 120. The valve seat 111 and the sleeve 114 are fixed, limitedly connected or are an integral structure. At least part of the limiting member 112 is located radially outside the valve seat 111. Specifically, the iron core assembly 113 includes a static iron core 1131 and a moving iron core 1132. Along the axial direction of the valve component 11, the static iron core 1131 is located on the side away from the valve core assembly 115, and the moving iron core 1132 is located on the side away from the valve core assembly 115. On the side close to the valve core assembly 115, the static iron core 1131 is fixedly connected to the wall forming the sleeve cavity 1140, and part of the moving iron core 1132 can move inside the sleeve cavity 1140. The valve core assembly 115 is located in the valve cavity 1110. Along the axial direction of the valve component 11, the moving iron core 1132 can drive the valve core assembly 115 to move axially in the valve cavity 1110, and the valve core assembly 115 can open and close the valve port 1113; in other embodiments, the moving iron core 1132 can also be located on the side away from the valve core assembly 115, and the static iron core 1131 is located on the side close to the valve core assembly 115.

[0048] Combine Figure 4 、 Figure 6 and Figure 16Furthermore, the valve core assembly 115 is fitted with a clearance between the wall forming the valve cavity 1110, and the outer diameter of the valve core assembly 115 is larger than the inner diameter of the wall forming the sleeve cavity 1140. The step wall between the valve cavity 1110 and the sleeve cavity 1140 limits the valve core assembly 115 from escaping the valve cavity 1110. With this arrangement, the inner diameters of the wall forming the valve cavity 1110 and the wall forming the sleeve cavity 1140 are different, which facilitates the separate processing of the wall forming the sleeve cavity 1140 and the wall forming the valve cavity 1110, and is conducive to reducing the processing error of the wall forming the valve cavity 1110 by stretching, and reducing the risk of the valve core assembly 115 being stuck between the walls forming the valve cavity 1110.

[0049] Combine Figures 4 to 7 as well as Figure 10 The coil assembly 13 has an induction cavity 130, and at least part of the sleeve 114 is located in the induction cavity 130. The coil assembly 13 includes a shell 131 and a winding 133. Specifically, the shell 131 is made of PPS plastic, and the shell 131 is injection molded. The winding 133 is injection molded inside the shell 131. The induction cavity 130 is located radially inside the winding 133. Along the axial direction of the valve component 11, the coil assembly 13 is axially in contact with the valve seat 111. Along the axial direction of the valve component 11, the valve component 11 is axially pressed between the shell 131 and the wall forming the accommodating cavity 120.

[0050] Combine Figures 4 to 7 Furthermore, in the present embodiment, the valve body 12 includes a support portion 121, and the inner diameter of at least part of the wall forming the accommodating cavity 120 is smaller than the outer diameter of the support portion 121. Specifically, along the axial direction of the valve component 11, the support portion 121 is located between the wall forming the mounting groove 1200 and the coil assembly 13, and the wall forming the accommodating cavity 120 includes the support portion 121, and the support portion 121 is an annular step wall. Along the axial direction of the valve component 11, the limiter 112 is axially pressed between the shell 131 and the support portion 121, and the opposite two ends of the limiter 112 are axially abutted against the support portion 121 and the end wall of the coil assembly 13 close to the valve body 12; in other embodiments, the support portion 121 can also be an irregular shape, and the support portion 121 can be formed from the wall of the accommodating cavity 120 It protrudes radially inward; the inner diameter of the wall of the accommodating cavity 120 is increased or remains roughly unchanged since the support portion 121 points to the direction of the coil assembly 13, and the valve component 11 is axially pressed between the support portion 121 and the shell 131. In this way, the valve component 11 is axially abutted against the support portion 121. After the shell 131 and the valve component 11 are axially abutted, the coil assembly 13 and the valve body 12 are fixed or limitedly connected to complete the assembly of the valve device 1, which is conducive to reducing the assembly steps of the valve device 1. At the same time, the shape of the abutting portion of the shell 131 and the valve component 11 is adapted to the shape of the valve component 11 during the injection molding process, thereby increasing the area of ​​the abutting portion of the shell 131 and the valve component 11, thereby reducing the pressure borne by the shell 131, and further reducing the risk of damage to the shell 131 due to excessive pressure.

[0051] Combine Figures 4 to 7 , a first embodiment of the valve device 1, regarding the connection structure of the coil assembly 13 and the valve body 12; in this embodiment, the coil assembly 13 and the valve body 12 are fastened by a bolt 14A, and the valve device 1 also includes a bolt 14A, the coil assembly 13 has a through hole 134, and the valve body 12 has a threaded hole 123, the threaded hole 123 and the through hole 134 are arranged correspondingly, the bolt 14A is threadedly connected to the wall forming the threaded hole 123, and along the axial direction of the valve component 11, the peripheral portion of the through hole 134 is axially pressed between the nut of the bolt 14A and the peripheral portion of the threaded hole 123; with this arrangement, the bolt 14A can provide greater pressure on the coil assembly 13, which helps to reduce the risk of the valve component 11 forcing the coil assembly 13 to separate from the valve body due to the pressure of the fluid medium inside the accommodating chamber 120.

[0052] Combine Figure 3 and Figure 4 Furthermore, a plurality of through holes 134 are provided around the circumference of the valve component 11, and the circumferential intervals between adjacent through holes 134 are roughly equal; such a setting can balance the pressure between the coil assembly 13 and the valve body 12, which is beneficial to improving the connection stability between the coil assembly 13 and the valve body 12.

[0053] Combine Figure 4 、 Figure 5 In the first embodiment of the valve device 1, the first embodiment of the coil assembly 13, the coil assembly 13 includes a pressure sleeve 135, the pressure sleeve 135 is made of a material with a hardness greater than that of the housing 131. In this embodiment, the pressure sleeve 135 is made of metal or alloy material, the pressure sleeve 135 is cylindrical, the pressure sleeve 135 is embedded in the housing 131, and the housing 131 is injection molded. The bolt 14A is located radially inside the pressure sleeve 135, and the pressure sleeve 135 is axially pressed against the nut of the bolt 14A to form a thread. Between the peripheral parts of the hole 123, one axial end of the pressure-bearing sleeve 135 axially abuts against the nut of the bolt 14A, and the other axial end of the pressure-bearing sleeve 135 abuts against the peripheral part forming the threaded hole 123; this arrangement helps to reduce the risk of the nut of the bolt 14A exerting excessive pressure on the coil assembly 13 and causing damage to the coil assembly 13. The pressure-bearing sleeve 135 is injection-molded in the shell 131, and the connection surface between the pressure-bearing sleeve 135 and the shell 131 is large, which helps to improve the connection strength between the pressure-bearing sleeve 135 and the shell 131.

[0054] Furthermore, the outer side wall where the pressure sleeve 135 is connected to the shell 131 is rough or has a concave-convex structure. This arrangement helps to improve the connection strength between the pressure sleeve 135 and the shell 131, and helps to reduce the risk of separation of the pressure sleeve 135 and the shell 131.

[0055] Furthermore, a washer can be provided between one axial end of the pressure sleeve 135 and the nut of the bolt 14A. Along the axial direction of the bolt 14A, one axial end of the washer is axially abutted against the pressure sleeve 135, and the other axial end of the washer is axially abutted against the nut of the bolt 14A. This arrangement helps to further reduce the risk of the shell 131 being broken and damaged due to excessive pressure from the nut of the bolt 14A on the coil assembly 13.

[0056] Combine Figure 6 、 Figure 7 as well as Figure 10 In the first embodiment of the valve device 1, the second embodiment of the coil assembly 13, compared with the first embodiment of the coil assembly 13, the coil assembly 13 further includes a magnetic conductive plate 132, the magnetic conductive plate 132 is located on the axial side of the winding 133, the magnetic conductive plate 132 can reduce the magnetic resistance, the winding 133 and the magnetic conductive plate 132 are both embedded in the shell 131, the pressure sleeve 135 and the magnetic conductive plate 132 are fixed, limitedly connected or integrated. Specifically, the magnetic conductive plate 132 and the pressure sleeve 135 are an integrated structure, and along the axial direction of the through hole 134, the pressure sleeve 135 is automatically The magnetic conductive plate 132 is stretched toward the side close to the valve body 12, and the bolt 14A is located radially inside the pressure sleeve 135. The pressure sleeve 135 is axially pressed between the nut of the bolt 14A and the peripheral portion forming the threaded hole 123. One axial end of the pressure sleeve 135 is axially abutted against the nut of the bolt 14A, and the other axial end of the pressure sleeve 135 is abutted against the peripheral portion forming the threaded hole 123. With this arrangement, on the one hand, the magnetic conductive plate 132 and the pressure sleeve 135 that are integrally structured or welded and fixed can enhance the connection strength between the pressure sleeve 135 and the shell 131.

[0057] Furthermore, the magnetic plate 132 is substantially perpendicular to the axial direction of the winding 133. In this way, the magnetic plate 132 is substantially perpendicular to the axial direction of the winding 133. The magnetic plate 132 can disperse the preload force, which can further enhance the connection strength between the pressure sleeve 135 and the housing 131.

[0058] Furthermore, the magnetic conductive plate 132 has a sensing hole 1320 that passes through the magnetic conductive plate 132, and the wall forming the sensing cavity 130 includes the wall forming the sensing hole 1320, and the inner diameter of the wall forming the sensing hole 1320 is smaller than the maximum outer diameter of the valve component 11; with this arrangement, after the valve device 1 is assembled, the magnetic conductive plate 132 provides the main pre-tightening force along the axial direction of the valve component 11, which can further disperse the pressure between the shell 131 and the magnetic conductive plate 132, reduce the pressure between the contact surface of the shell 131 and the magnetic conductive plate 132, and reduce the risk of damage to the shell 131.

[0059] Combine Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9as well as Figure 12 Furthermore, the outer diameter of the valve seat 111 is larger than the outer diameter of the sleeve 114, and at least part of the step wall between the valve seat 111 and the sleeve 114 forms an abutment wall 116. Along the axial direction of the valve component 11, the coil assembly 13 axially abuts the abutment wall 116. Specifically, at least part of the lower end wall of the shell 131 axially abuts the abutment wall 116. With this arrangement, the abutment wall 116 can increase the contact area between the coil assembly 13 and the valve component 11, disperse the pressure between the coil assembly 13 and the valve component 11, reduce the pressure on the abutment surface of the coil assembly 13 and the valve component 11, and effectively reduce the risk of damage to the abutment surface of the coil assembly 13 and the valve component 11 due to excessive pressure.
