Description

Technical Field

[0001] The present invention belongs to the technical field of automobile thermal management devices, and in particular relates to a valve island assembly with a distributed structure on the agent side of a stamped flow channel plate and a production process thereof. Background Art

[0002] As new energy vehicles, especially pure electric vehicles, put forward more stringent requirements for the lightweight, low cost and high reliability of the "three-electric system", the manufacturing technology of the refrigerant side thermal management module (referred to as "agent side thermal management module") is becoming the focus of the industry. Among them, the core component that carries the refrigerant circulation and heat exchange functions, the agent side flow plate, its molding method directly determines the quality of the whole machine, production cost and leakage risk.

[0003] The industry currently mainly follows two technical routes: one is the "forging-CNC finishing" model. This model first forges aluminum alloy or stainless steel billets into near-net-shape blanks, and then processes the flow channels and sealing surfaces through multiple CNC cutting processes. Although the forgings have dense structure, the blanks themselves are expensive, the processing time is long, and there are many fixtures, which makes the cost of each piece continue to rise; at the same time, in order to ensure forging filling and structural rigidity, a thicker margin must be retained during design. The final product is generally 25%-40% heavier than similar castings, which is difficult to meet the urgent lightweight needs of pure electric vehicles.

[0004] Another route is "die casting or gravity casting + post-processing". This process uses high-pressure or gravity casting to form the runner plate, and then deburrs, machine and vacuum braze. However, the melt filling and cooling during the casting process are prone to defects such as sand holes, shrinkage and pores, resulting in a pass rate of only about 30%-40% in the vacuum brazing stage, and a large number of scrapped parts have invisibly pushed up material and labor costs. More importantly, even if qualified castings are screened out through testing, their remaining micro-defects may still evolve into leakage channels under the thermal cycles and vibration loads of the vehicle in service, weakening the system reliability and increasing the risk of leakage in the entire vehicle.

[0005] It can be seen that the existing forging and casting manufacturing solutions are difficult to take into account lightweight, low cost, high yield and high reliability at the same time: forging parts are too heavy and expensive, while casting parts are light but have high defect rates; the former has complex processes and poor production line flexibility, while the latter has a high scrap rate and prominent leakage risks. The industry urgently needs a new agent side runner plate manufacturing solution that combines structural innovation and process innovation to break through the current bottleneck and meet the rapidly growing pure electric vehicle market demand. Summary of the invention

[0006] The purpose of the present invention is to solve the deficiencies of the above-mentioned background technology and to provide a valve island assembly with a distributed structure on the agent side of a stamped flow channel plate and a production process thereof.

[0007] The technical solution adopted by the present invention is as follows: A valve island assembly with a distributed structure on the agent side of a stamping type runner plate, comprising a bottom plate assembly, a stamping type runner plate brazed to the bottom plate assembly, various valve mounting seats, and a plurality of modular interface flanges. The stamping type runner plate is relatively fitted with the brazing surface of the bottom plate assembly on the bottom plate assembly through the brazing surface of the stamping type runner plate thereon. The stamping type runner plate is provided with a plurality of runner structures. The various valve mounting seats are fixed on the plurality of runner structures, and the plurality of modular interface flanges are mounted on the side of the stamping type runner plate.

[0008] In the above technical solution, the integrated brazing of the runner plate formed by stamping and the bottom plate assembly reduces the number of components and connection surfaces, and the overall structure is more compact and reliable; the distributed structure design can flexibly arrange the runners and valve parts, facilitating modular combination according to different vehicle models or refrigerant flow path requirements; compared with the traditional forging or casting methods, it is easier to achieve lightweight and high-efficiency mass production, effectively reducing costs and machining allowances.

[0009] Preferably, the plurality of modular interface flanges include a first Z-direction interface flange, a first Y-direction interface flange, a second Y-direction interface flange, a third Y-direction interface flange, and a fourth Y-direction interface flange. Three positioning plates connected end to end are provided on the back of each of the above interface flanges. The side surfaces of the positioning plates form a flange runner Y-direction positioning surface, a flange and runner Z-direction positioning surface, and a flange and runner X-direction positioning surface. The side surface of the plurality of runner structures at the edge of the stamping type runner plate is a runner and flange side positioning surface. The plurality of modular interface flanges and the stamping type runner plate are positioned in the X, Y, and Z directions through the flange and runner Y-direction positioning surface, the flange and runner Z-direction positioning surface, the flange and runner X-direction positioning surface, and the runner and flange side positioning surface.

[0010] In the above technical solution, different interface flanges can be independently selected and quickly replaced according to the actual flow direction or pipeline layout, greatly improving adaptability; the three-direction positioning surfaces formed by the positioning plates cooperate with the stamping type runner plate to ensure the accurate alignment of the flange and the runner plate in the X, Y, and Z directions, improving the assembly accuracy and airtightness; the modular design facilitates standardized production and later maintenance, reducing the investment in special fixtures or customized parts.

[0011] Preferably, the assembly directions of the first Y-direction interface flange and the fourth Y-direction interface flange in the horizontal direction are opposite to those of the second Y-direction interface flange and the third Y-direction interface flange. The pipe sizes for connection of the first Y-direction interface flange, the second Y-direction interface flange, and the third Y-direction interface flange are all different. The pipe sizes for connection of the first Y-direction interface flange, the third Y-direction interface flange, and the fourth Y-direction interface flange are all different.

[0012] In the above technical solution, through reverse assembly, interference between interface flanges is avoided, which is conducive to compact arrangement and the later pipeline routing; flanges with different diameters can achieve refined management of refrigerant flow / pressure, enabling the system to operate efficiently under various working conditions; after optimized layout, it is convenient to achieve zoning control or branch heat exchange, improving the flexibility of vehicle refrigeration / heating.

[0013] More preferably, the bottom plate assembly includes a bottom plate, and a heat exchanger flange interface and a heat exchanger mounting post fixed to the bottom surface of the bottom plate. The heat exchanger flange interface and the heat exchanger mounting post are arranged on the bottom plate by an integrated molding method.

[0014] More preferably, the multiple valve mounting seats include a solenoid valve mounting seat and an electronic expansion valve mounting seat, which are respectively used for mounting a solenoid valve and an electronic expansion valve.

[0015] More preferably, a first positioning reference hole is provided at the bottom of the solenoid valve mounting seat, a second positioning reference hole is provided at the bottom of the electronic expansion valve mounting seat, a third positioning reference hole and a fourth positioning reference hole are provided at the top of multiple flow channel structures, and the solenoid valve mounting seat, the electronic expansion valve mounting seat and the stamping type flow channel plate are assembled by matching the first positioning reference hole, the second positioning reference hole with the third positioning reference hole and the fourth positioning reference hole.

[0016] In the above technical solution, it ensures that the valve mounting seat and the flow channel structure have a clear mating reference during installation, reducing misalignment or offset; it helps the close contact of the brazing joint surface, improving the brazing quality and sealing performance; it facilitates subsequent automated or semi-automated assembly processes and reduces human operation errors.

[0017] More preferably, the bottom plate assembly is provided with a non-brazing surface of the bottom plate assembly, which is used to arrange the required sensors or fasteners, isolating them from the brazing surface of the bottom plate assembly to avoid interference with the brazing area.

[0018] More preferably, it further includes a brazing fixture, which includes a brazing fixture spring, a spring pressing block and a brazing fixture bottom plate, and compresses and fixes the stamping type flow channel plate, multiple modular interface flanges and the bottom plate assembly during the brazing process.

[0019] In the above technical solution, it ensures the relative position stability of each component during the brazing process, and it is not easy to misalign or warp; it can apply uniform pressing force at multiple points and in multiple directions to achieve full fitting and reliable weld quality; it improves the airtightness and strength performance of the post-weld finished product and enhances the first-pass production qualification rate.

[0020] More preferably, the brazing fixture cooperates with the spring pressing block through the brazing fixture spring to achieve multi-directionally adjustable pressing of the stamping type flow channel plate and multiple modular interface flanges before and during brazing, preventing misalignment or deformation of the flow channel plate and the flange; the brazing fixture bottom plate is arranged below the bottom plate assembly and aligned with the third positioning reference hole and the fourth positioning reference hole, so as to form a consistent brazing reference plane during overall assembly.

[0021] In the above technical solution, the adjustable spring pressing method can finely adjust the clamping force according to the deformation of the parts, reducing stress concentration and deformation of the flow channel plate or flange in a high-temperature environment; through the cooperation of the fixture bottom plate and the positioning reference hole, the consistency of the assembly and brazing reference surfaces is ensured, improving the overall assembly accuracy; avoiding soldering defects, slag inclusion or welding deformation caused by uneven local stress, and further ensuring the product quality and stability.

[0022] A production process of a fluid side distributed structure valve island assembly for a stamping type flow channel plate includes the following steps:

[0023] Step 1, stamping of the bottom plate assembly: Select a brazable aluminum alloy or stainless steel plate, stamp or press the bottom plate into shape, and integrally form a heat exchanger flange interface and a heat exchanger mounting post at the same time;

[0024] Step 2, stamping of the stamping type flow channel plate: Select a flat blank of the corresponding material, and obtain a stamping type flow channel plate provided with a plurality of flow channel structures through a stamping process, and form a flow channel, a flange side positioning surface and related positioning reference holes at the edge of the flow channel plate;

[0025] Step 3, arrange the first Z-direction interface flange, the first Y-direction interface flange, the second Y-direction interface flange, the third Y-direction interface flange, the fourth Y-direction interface flange and various valve mounting seats around and on the top of the stamping type flow channel plate in a preset direction; utilize the cooperation between the flange and the flow channel Y-direction positioning surface, the flange and the flow channel Z-direction positioning surface, the flange and the flow channel X-direction positioning surface and the flow channel and flange side positioning surface, as well as the first positioning reference hole, the second positioning reference hole, the third positioning reference hole and the fourth positioning reference hole, to accurately align each flange and various valve mounting seats with the stamping type flow channel plate;

[0026] Step 4, align and fit the stamping type flow channel plate with the bottom plate assembly so that the brazing surfaces of the stamping type flow channel plate and the bottom plate assembly are relatively fitted; through the brazing fixture spring, spring pressing block and brazing fixture bottom plate of the brazing fixture, integrally press and fix the stamping type flow channel plate, multiple modular interface flanges and the bottom plate assembly; place the tightly assembled component into a vacuum brazing furnace or other brazing equipment, and perform vacuum brazing according to a predetermined temperature curve;

[0027] Step 5: After brazing is completed, cool down and remove the brazing fixture, and perform leak detection tests or sealing tests on the brazing connection quality; if sensors or fasteners need to be installed, arrange the relevant components on the non-brazed surface of the bottom plate assembly, and finally obtain an integrated agent-side distributed structure valve island assembly of the stamping flow channel plate.

[0028] In the above technical solution, by sequentially performing the stamping of the bottom plate assembly, the forming of the stamping flow channel plate, the precise arrangement and positioning of various valve mounting seats and modular interface flanges, vacuum brazing assembly, and subsequent leak detection and sensor (or fastener) installation, the present invention has achieved significant improvements in terms of lightweight, manufacturing efficiency, assembly accuracy, and sealing reliability: reducing material redundancy and increasing structural strength through stamping, and making each connection surface closely fit through vacuum brazing combined with multi-directionally adjustable pressing, significantly reducing the risks of leakage and scrapping; at the same time, the modular interface flanges and distributed valve island layout facilitate quick adaptation to different bore diameters and flow path requirements, and there is space on the non-brazed surface of the bottom plate assembly to install sensors or fasteners after the high-temperature process is completed, further improving the maintainability and applicability of the system, thus providing an efficient, reliable, and scalable solution for the refrigerant-side thermal management of new energy vehicles.

[0029] Through the comprehensive technical means of "stamping flow channel plate + distributed valve island structure + vacuum brazing integrated connection", the present invention has effectively improved the high cost, high scrap rate, and large weight of the existing forged or cast flow channel plates, and can stably obtain a valve island assembly with both lightweight, high strength, and high airtightness in mass production, significantly enhancing the comprehensive performance and market competitiveness of the thermal management module of new energy vehicles.

[0030] After the stamping flow channel plate, various valve mounting seats, multiple modular interface flanges and the bottom plate assembly are brazed into a valve island assembly, they are assembled with the required valves to form a thermal management integration module for the refrigerant side. The agent-side distributed structure valve island assembly of the stamping flow channel plate can make the agent-side thermal management module lightweight, reduce the overall weight of the agent-side thermal management module, significantly reduce the part cost, and increase the revenue.

[0040] As Figures 1 to 3As shown in the figure, multiple modular interface flanges include a first Z-direction interface flange 5, a first Y-direction interface flange 6, a second Y-direction interface flange 7, a third Y-direction interface flange 8, and a fourth Y-direction interface flange 9. Three positioning plates connected end to end are provided on the back of each of the above interface flanges. The side surfaces of the positioning plates form a Y-direction positioning surface A of the flange flow channel, a Z-direction positioning surface B between the flange and the flow channel, and an X-direction positioning surface C between the flange and the flow channel. The side surfaces of the edges of the stamping flow channel plate 4 where multiple flow channel structures are located are the side positioning surface F between the flow channel and the flange. The multiple modular interface flanges and the stamping flow channel plate 4 are positioned in the X, Y, and Z directions through the Y-direction positioning surface A between the flange and the flow channel, the Z-direction positioning surface B between the flange and the flow channel, and the X-direction positioning surface C between the flange and the flow channel and the side positioning surface F between the flow channel and the flange.

[0041] The assembly directions of the first Y-direction interface flange 6 and the fourth Y-direction interface flange 9 in the horizontal direction are opposite to those of the second Y-direction interface flange 7 and the third Y-direction interface flange 8. The pipe sizes for connection of the first Y-direction interface flange 6, the second Y-direction interface flange 7, and the third Y-direction interface flange 8 are all different. The pipe sizes for connection of the first Y-direction interface flange 6, the third Y-direction interface flange 8, and the fourth Y-direction interface flange 9 are all different.

[0042] As Figure 4 shown in the figure, the bottom plate assembly 3 includes a bottom plate 310, and a heat exchanger flange interface 311 and a heat exchanger mounting post 312 fixed to the bottom surface of the bottom plate 310. The heat exchanger flange interface 311 and the heat exchanger mounting post 312 are provided on the bottom plate 310 by an integrated molding method.

[0043] Multiple valve mounting seats include a solenoid valve mounting seat 1 and an electronic expansion valve mounting seat 2, which are respectively used for mounting a solenoid valve and an electronic expansion valve.

[0048] The stamping flow channel plate 4 uses a double-sided clad material of 6063 aluminum alloy material, which is convenient for direct welding with valve mounting seats and multiple modular interface flanges, reducing the number of solder sheet parts. The bottom plate 310 uses a 3003mod 3mm 5% single-sided composite material instead of double-sided cladding, reducing the waste of clad material. The stamping flow channel plate 4 designs corresponding battery cooling and heating channels according to the system principle requirements, and realizes part processing through stamping technology and stamping dies, reducing the overall weight of the valve island welding assembly, achieving lightweight.

[0055] Step 5, after brazing is completed, cool and remove the brazing fixture 10, and perform a leak test or a sealing test on the brazing connection quality; if sensors or fasteners need to be installed, arrange the relevant components on the non-brazing surface K of the base plate assembly, and finally obtain an integrated stamped flow channel plate with a distributed structure valve island assembly on the agent side.

[0056] During the brazing process, the spring clamping force is used to clamp the parts to ensure that the gap between the parts is ≤0.1mm, which makes it easy to braze all the components into one and realize a lightweight valve island welding assembly.

The weight can be reduced by about 0.8kg compared with the current mass production forging solution, and the cost can be reduced by nearly 90 yuan per piece. See the table below for details:
