Description

Technical Field

[0001] This application relates to the field of thermal management technology, specifically to a one-way valve assembly and an integrated assembly. Background Technology

[0002] In the integrated components of related technologies, a one-way valve is installed in the fluid channel to realize the one-way flow of fluid. Among them, the duckbill one-way valve is usually made of elastic material. Its duckbill part has a flat structure and a slit-type valve port at the front end of the duckbill part. When the valve port is opened into a nearly circular channel, a larger flow rate is achieved. When the valve port is pressed and closed, the flow of medium is blocked.

[0003] However, when a duckbill-type check valve is subjected to radial impact force, its duckbill part will become skewed. Prolonged skewness may cause irreversible deformation of the duckbill part, leading to the failure of the check valve. Utility Model Content

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solution of this application, the embodiments of this application will be further described below with reference to the accompanying drawings:

[0036] The integrated components of the technical solution of this application can be implemented in various ways. At least one of these implementations can be applied to a vehicle thermal management system, and at least one of these implementations can be applied to other thermal management systems such as a home thermal management system or a commercial thermal management system. The fluid in the fluid management device can be coolant, oil, or other media. The following description uses a fluid management device applied to a vehicle thermal management system as an example, in conjunction with the accompanying drawings.

[0037] Please refer to Figures 1-9 , Figure 1 This is a three-dimensional structural diagram of a specific embodiment of the one-way valve assembly provided in this application; Figure 2 for Figure 1 A schematic diagram of a one-way valve assembly viewed from one direction. Figure 3 for Figure 2 A cross-sectional view of the one-way valve assembly along the AA direction; Figure 4 for Figure 1 Exploded view of the structure in a one-way valve assembly; Figure 5 for Figure 4 A schematic diagram of the one-way valve body in one direction of a one-way valve assembly; Figure 6 for Figure 4 A schematic diagram of the protective cover in a one-way valve assembly; Figure 7 for Figure 5 A schematic diagram of the one-way valve body from another direction; Figure 8 for Figure 5 A schematic diagram of the third angle of the one-way valve body; Figure 9 for Figure 6 A schematic diagram of the protective shield from another direction.

[0038] This embodiment provides a one-way valve assembly 01, including:

[0039] One-way valve body 1, the one-way valve body 1 includes a duckbill part 11, one end of the duckbill part 11 has a slit-type valve port 111;

[0040] The protective cover 2 covers at least the outer periphery of the duckbill portion 11. The end of the protective cover 2 has a grid portion 21 with a grid hole 21a. The valve port 111 communicates with the grid hole 21a.

[0041] In this embodiment, a protective cover 2 is added to the one-way valve assembly 01. The protective cover 2 covers at least the outer periphery of the duckbill portion 11. In this way, the radial impact force generated by the fluid acts directly on the protective cover 2, that is, the protective cover 2 bears the radial impact force generated by the fluid, protecting the duckbill portion 11 from the radial impact force and minimizing the possibility of the duckbill portion 11 becoming misaligned. At the same time, the end of the protective cover 2 has a grid portion 21, which can filter out the scouring effect of the fluid medium, reduce the impact of vortices and other impacts formed inside the one-way valve assembly 01, and minimize the possibility of irreversible deformation of the valve port 111 due to the long-term misalignment of the duckbill portion 11, thus solving the potential failure problem of the one-way valve assembly 01.

[0042] It should be noted that the axial direction of the check valve assembly 01 is the flow direction of the working medium passing through the check valve assembly 01, and the radial direction of the check valve assembly 01 is perpendicular to the axial direction of the check valve assembly 01. It can be understood that the axial direction of the check valve assembly 01 is also the direction in which the axis of the check valve assembly 01 extends.

[0043] Further, please refer to Figure 5 and Figure 6 In this embodiment, the valve port 111 extends radially along the one-way valve body 1, and the grille hole 21a extends radially along the protective cover 2. The direction in which the valve port 111 extends is defined as the first direction 101, and the direction in which the grille hole 21a extends is defined as the second direction 102. The first direction 101 and the second direction 102 are parallel. With this arrangement, the impact of vortices and other impacts formed inside the one-way valve assembly 01 can be further reduced, the impact force generated by the fluid perpendicular to the duckbill portion 11 can be further reduced, the impact of the impact force perpendicular to the first direction 101 on the duckbill portion 11 can be further reduced, and the possibility of the duckbill portion 11 becoming misaligned can be further reduced.

[0044] Furthermore, such as Figure 3 As shown, the one-way valve body 1 has an extension hole 1a, which communicates with the valve port 111. The protective cover 2 has a mating hole 2a. The one-way valve body 1 is at least partially located in the mating hole 2a. The one-way valve body 1 and the protective cover 2 are fixedly connected. The fixed connection method includes, but is not limited to, bonding, interference fit, welding, secondary plastic coating, threaded connection or snap-fit.

[0045] When the check valve body 1 and the protective cover 2 are connected by bonding, welding, or secondary plastic coating, it is beneficial to improve the connection reliability of the check valve body 1 and the protective cover 2. When the check valve body 1 and the protective cover 2 are connected by interference fit, threaded connection, or snap-fit, that is, the check valve body 1 and the protective cover 2 adopt a detachable connection method, it is convenient to maintain or replace the check valve body 1 or the protective cover 2. If one of the check valve body 1 and the protective cover 2 fails, it is not necessary to scrap the other, thus saving materials and reducing costs.

[0046] like Figure 6 As shown, the grille holes 21 extend along the second direction 102 to the wall corresponding to the mating hole 2a. This maximizes the flow cross-sectional area of ​​the one-way valve assembly 1. The number of grille holes 21 is multiple, which effectively transforms the large vortex entering the mating hole 2a into a small vortex, thereby reducing the impact force on the duckbill portion 11.

[0047] While ensuring the cross-sectional area of ​​the flow passage of the one-way valve assembly 01, the vortex entering the mating hole 2a is further reduced. As one way to achieve this, the ratio of the width of the grille hole 21a in the radial direction of the protective cover 2 and perpendicular to the second direction 102 to the depth of the grille hole 21a in the axial direction of the protective cover 2 and perpendicular to the second direction 102 is 1:3. In this way, the size of the vortex entering the mating hole 2a can be reduced as much as possible, which is beneficial to reducing the fluid impact on the duckbill part 11.

[0048] like Figure 3 As shown, along the axial direction of the protective cover 2, there is a predetermined distance between the end of the duckbill portion 11 and the inner wall of the grid portion 21; in this way, the pressure of the duckbill portion 11 on the protective cover 2 due to temperature can be effectively reduced, which is beneficial to reducing the deformation of the duckbill portion 11.

[0049] Furthermore, in this embodiment, the one-way valve body 1 also includes a cylindrical portion 12, which is connected to the duckbill portion 1111; at least a portion of the extension hole 1a is formed in the cylindrical portion 12. Specifically, the duckbill portion 11 has a flat structure, and the ratio of the thickness of the duckbill portion 11 in the direction perpendicular to the first direction 101 to the length of the duckbill portion 11 in the direction parallel to the first direction 101 does not exceed 1:2. In this way, when the one-way valve assembly 01 is circulated with the working medium, it is beneficial to ensure that the cross-sectional area of ​​the duckbill portion 11 is approximately the same as the cross-sectional area of ​​the extension hole 1a. At the same time, it effectively ensures the structural strength of the duckbill portion 11 and helps to reduce the impact of eddy current impact force on the duckbill portion 11.

[0050] It should be noted that: the normal flow direction of the working medium in the duckbill section 11 is from the extension hole 1a to the valve port 111; the flow direction from the valve port 111 to the extension hole 1a is the abnormal flow direction of the working medium. The valve port 111 of the duckbill section 11 can shut off the abnormal flow of the working medium. The length of the duckbill section 11 along the axial direction of the one-way valve body 1 is approximately the same as the length of the cylindrical section 12 along the axial direction of the one-way valve body 1. This length setting ensures that the valve port of the duckbill section 11 can open normally when the working medium is flowing normally. The length of the duckbill section extending along the first direction 101 does not exceed the outer wall of the cylindrical section 12.

[0051] The material of the duckbill 11 can be a material with a certain elastic deformation; the material of the protective cover 2 can be polypropylene (PP). In this way, the duckbill 11 can be effectively protected and the impact of the eddy current generated by the working medium on the duckbill 11 can be reduced.

[0052] Please continue to refer to this. Figure 3 and Figure 4 In this embodiment, the one-way valve assembly 01 further includes a support frame 3, which is at least partially installed inside the cylindrical portion 12. The outer peripheral wall of the support frame 3 is at least partially fitted with the inner peripheral wall of the cylindrical portion 12. The support frame 3 has a flow hole 3a, which communicates with the valve port 111. This prevents the support frame 3 from interfering with the flow of fluid, ensuring smooth fluid flow and thus ensuring that the one-way valve assembly 01 can properly control the unidirectional flow of fluid. As described above, the support frame 3 is located inside the cylindrical portion 12, providing support to the cylindrical portion 12 from the inside out, minimizing the possibility of deformation of the cylindrical portion 12 due to fluid impact, and minimizing the possibility of failure of the one-way valve body 1. Polypropylene (PP) can be selected as the material for the support frame 3; this can effectively support the extension hole 1a of the duckbill portion 11, reducing the deformation of the one-way valve body 1.

[0053] The connection method between the support frame 3 and the check valve body 1 is not limited. For example, the support frame 3 and the check valve body 1 can be connected by bonding, interference fit, welding, secondary plastic coating, threaded connection, or snap-fit. When the support frame 3 and the check valve body 1 are connected by bonding, welding, or secondary plastic coating, it improves the connection reliability. When the support frame 3 and the check valve body 1 are connected by interference fit, threaded connection, or snap-fit, i.e., the support frame 3 and the check valve body 1 adopt a detachable connection method, it facilitates the maintenance or replacement of either the check valve body 1 or the support frame 3. If one of the check valve body 1 or the support frame 3 fails, the other does not need to be scrapped, saving materials and reducing costs.

[0054] like Figures 3-5 As shown, in this embodiment, the outer periphery of the one-way valve body 1 has a stepped surface 13 facing the duckbill portion 11, and the end wall of the protective cover 2 facing away from the grille portion 21 abuts against the stepped surface 13.

[0055] As set above, the stepped surface 13 can limit the position of the protective cover 2. During the assembly of the protective cover 2, when the end wall of the protective cover 2 facing away from the grid part 21 abuts against the stepped surface 13, it indicates that the protective cover 2 is in the preset installation position, and the protective cover 2 and the one-way valve body 1 can be connected, thereby improving the assembly efficiency of the protective cover 2 and improving the positional accuracy of the protective cover 2.

[0056] This embodiment provides an integrated component having a fluid channel. The integrated component includes the aforementioned one-way valve component, and the one-way valve component 01 is installed inside the fluid channel.

[0057] The integrated component in this embodiment includes the aforementioned one-way valve component 01, and therefore has the same technical effects as the aforementioned one-way valve component 01, which will not be repeated here.

[0058] Please refer to Figures 10-11 , Figure 10 This is a schematic diagram of the structure of a specific embodiment of the integrated component provided in this application; Figure 11 for Figure 10 A cross-sectional view of the integrated component along the BB direction.

[0059] In this embodiment, the integrated component includes a kettle 02 and a flow channel plate 03 that are interconnected, and a one-way valve assembly 01 is located at the connection between the kettle 02 and the flow channel plate 03.

[0060] As configured above, depending on the installation direction of the one-way valve assembly 01, one-way flow of fluid can be achieved from the kettle 02 to the flow channel plate 03, or one-way flow of fluid can be achieved from the flow channel plate 03 to the kettle 02. In one specific implementation, the valve port 111 of the one-way valve body 1 is closer to the flow channel plate 03 than the kettle 02. Thus, in certain operating modes of the integrated assembly, it helps to reduce the flow of working medium from the flow channel plate 03 into the kettle 02.

[0061] In some embodiments of this application, the one-way valve assembly 01 includes a one-way valve body 1, a protective cover 2, and a support frame 3. The support frame 3 is fixedly connected to the one-way valve body 1, and the protective cover is fixedly connected to the one-way valve body 1. Either the protective cover 2 or the support frame 3 is integrally formed with either the kettle 02 or the flow channel plate 03.

[0062] As set up above, firstly, it can improve the connection reliability between the one-way valve assembly 01 and the kettle 02, or between the one-way valve assembly 01 and the flow channel plate 03, ensure the stable installation of the one-way valve assembly 01, improve the durability of the integrated assembly in this embodiment, and reduce the need for maintenance and repair; secondly, it can eliminate subsequent assembly processes and improve the production efficiency of the integrated assembly; thirdly, it can reduce the number of parts and avoid connection points in traditional structures, achieve optimized use of materials, and thus reduce the overall weight.

[0063] Furthermore, in this embodiment, at least one of the protective cover 2 and the support frame 3, which is integrally formed with the flow channel plate 03, is made of the same material as the flow channel plate 03, or at least one of the components integrally formed with the kettle 02 is made of the same material as the kettle 02.

[0064] As set above, the one-piece molded structure is made of a single material, which can improve the bonding strength between the protective cover 2 and the support frame 3 that is integrally molded with the flow channel plate 03 and the flow channel plate 03, or improve the bonding strength between the protective cover 2 and the support frame 3 that is integrally molded with the kettle 02 and the kettle 02, thereby improving the structural strength of the one-piece molded structure and further improving the installation stability of the one-way valve assembly 01.

[0065] In some other embodiments of this application, the one-way valve assembly 01 can also be manufactured as a separate product. The one-way valve assembly 01 includes a one-way valve body 1, a protective cover 2 and a support frame 3. The support frame 3 is fixedly connected to the one-way valve body 1, the protective cover is fixedly connected to the one-way valve body 1, and either the kettle 02 or the flow channel plate 03 is fixedly connected to the one-way valve assembly 01.

[0066] As set up above, the one-way valve assembly 01 is manufactured as a separate product. The one-way valve assembly 01 can be connected to any position in the fluid channel according to installation requirements, so as to achieve the purpose of controlling the direction of fluid flow at the required position.

[0067] Specifically, either the protective cover 2 or the support frame 3 is connected to either the kettle 02 or the flow channel plate 03 by means of bonding, welding, secondary plastic coating, threaded connection or snap-fit.

[0068] Among these methods, welding can improve the installation stability of the one-way valve assembly 01; the secondary plastic coating method refers to first processing either the protective cover 2 or the support frame 3 into shape, and then placing either the protective cover 2 or the support frame 3 into the processing mold of the kettle 02 or the flow channel plate 03. After processing the kettle 02 or the flow channel plate 03, either the protective cover 2 or the support frame 3 is naturally connected to the kettle 02 or the flow channel plate 03. This secondary plastic coating method is beneficial to improving the installation stability of the one-way valve assembly 01, as well as improving the product quality and performance; while the threaded connection or snap-fit ​​method can realize the detachable connection of the one-way valve assembly 01, which is convenient for replacing or repairing the one-way valve assembly 01 separately, avoiding the scrapping of other structures when the one-way valve assembly 01 fails, and saving costs.

[0069] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
