Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management technology, and in particular to a refrigerant side channel plate and integrated module. Background Technology

[0002] In recent years, automotive thermal management modules have shown a trend towards lightweighting, miniaturization, and high integration. Integrated modules, in particular, require the integration of refrigerant-side components such as expansion valves, shut-off valves, check valves, sensors, plate heat exchangers, and receiver-reservoir tanks. These components are numerous, structurally complex, and have high performance requirements, making their manufacturability design a key focus and challenge in automotive thermal management architecture. The integrated module needs to integrate these numerous refrigerant-side components onto a single flow channel plate. The refrigerant flows through the channels on the flow channel plate through the various components in the circuit to achieve multiple operating modes, including heating and cooling. The refrigerant-side flow channel plate has high requirements for sealing and strength, necessitating metal processing and resulting in a complex design structure.

[0003] Currently, most integrated modules are manufactured using a forging and brazing method. Forging forms the basic module structure with open flow channels. A large metal profile plate is then brazed onto these open flow channels to close them, creating a complete refrigerant loop flow channel plate. This method results in thicker, heavier, and more expensive modules, and it is difficult to manufacture complex structures. Another related technology uses die casting combined with small-area laser welding. This involves die casting to produce the basic structure of the integrated module, and then laser welding a cover plate to the mold opening to seal the flow channels.

[0004] However, as integrated modules become increasingly complex, welding is required in multiple directions on the modules, and the specifications of the welding cover plates vary, necessitating multiple flipping and welding processes during actual production. Existing refrigerant-side flow channel plates cannot meet these requirements; therefore, a new type of refrigerant-side flow channel plate is urgently needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a refrigerant side flow channel plate and an integrated module. The refrigerant side flow channel plate, through the structural arrangement of the flange portion, enables the opening and the cover plate to play a radial fixing role before welding, so as to achieve relative positioning, thereby improving the reliability and yield of welding. At the same time, the pre-positioning effect of this structure can meet the welding requirements of the integrated module.

[0006] This utility model embodiment discloses a refrigerant side flow channel plate, including:

[0007] The flow channel plate body is provided with multiple flow channels, at least a portion of which is a closed section integrally formed by the flow channel plate body, and the flow channel plate body has an opening communicating with the flow channel.

[0008] A cover plate is disposed in the opening of the flow channel plate body. The cover plate has a flange portion that extends outward along the radial direction of the cover plate and is interference-fitted with the side wall of the opening portion, so that the cover plate is radially fixed in the opening portion of the flow channel plate body. The cover plate and the opening portion of the flow channel plate body are welded together to seal the flow channel.

[0009] Furthermore, the outer contour of the cover plate on the welding plane matches the outer contour of the opening on the welding plane.

[0010] Furthermore, the outer contour of the cover plate on the welding plane includes a circular or racetrack shape.

[0011] Furthermore, the cover plate is provided with at least two flange portions, which are evenly arranged along the outer periphery of the cover plate.

[0012] Furthermore, the opening of the flow channel plate body is a stepped hole, the lower end face of the cover plate abuts against the stepped surface of the stepped hole, the upper end face of the cover plate is flush with the upper end face of the stepped hole, and the flange portion is interference-fitted with the inner wall of the stepped hole.

[0013] Furthermore, the upper end face of the stepped hole has a first chamfer at the connection with the inner wall of the stepped hole, and the cover plate has a second chamfer that matches the first chamfer. The cooperation between the first chamfer and the second chamfer can guide the cover plate to be pressed into the stepped hole.

[0014] Furthermore, the flange portion has a rib structure, and the large-diameter end of the flange portion is close to the cover plate, while the small-diameter end of the flange portion is away from the cover plate.

[0015] Furthermore, the outer circumferential surface of the cover plate is fitted with the inner wall of the stepped hole to allow the cover plate to be welded to the opening of the flow channel plate body by laser welding.

[0016] Furthermore, the flow channel plate body is made of aluminum alloy and is formed by semi-solid die casting.

[0017] This utility model embodiment also discloses an integrated module, including the refrigerant-side flow channel plate as described above. The flow channel plate body is provided with a plurality of external interfaces communicating with the flow channel, and the refrigerant-side component is fixedly connected to the flow channel plate body through the external interfaces.

[0018] The refrigerant side flow channel plate and integrated module provided by this utility model have the following beneficial effects, including but not limited to:

[0019] 1) The refrigerant side flow channel plate can achieve radial fixation of the opening and the cover plate before welding through the structure of the flange, so as to achieve relative positioning, thereby improving the reliability and yield of welding. At the same time, the pre-positioning effect of this structure can meet the welding requirements of integrated modules.

[0020] 2) The refrigerant side flow channel plate, through the clearance fit between the cover plate and the opening and the interference fit between the flange and the opening, can facilitate the control and relaxation of dimensional tolerances, thereby reducing welding costs; at the same time, the interference design of the opening and the local flange of the cover plate results in a small pressing force, which can reduce the risk of pressing damage, reduce the performance requirements of the press, reduce investment, and improve the yield rate.

[0021] 3) The refrigerant side flow channel plate uses laser welding of cover plates to seal the openings. Compared with sealing with threaded plugs and sealing rings, this saves space and machining costs, and avoids problems such as aging of sealing rings and poor performance under high and low temperature conditions, resulting in high reliability.

[0022] 4) This integrated module, by adopting the refrigerant side flow channel plate, can be applied to complex products that require welding on multiple sides, preventing the welding plate from falling off during the flipping process, facilitating automated production. In addition, unified pressing and then unified welding can improve the production cycle and reduce costs. Attached Figure Description

[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] Please refer to Figures 1-6 , Figure 1 A schematic diagram of the structure when the cover plate and the opening are fitted together according to an embodiment of this utility model; Figure 2 This is a schematic diagram of the structure of the opening 3 provided in an embodiment of the present utility model; Figure 3 A cross-sectional view of the opening 3 provided in an embodiment of this utility model; Figure 4 This is a schematic diagram of the structure of the cover plate 4 provided in an embodiment of the present utility model; Figure 5 A top view of the cover plate 4 provided in an embodiment of this utility model; Figure 6This is a cross-sectional view of the cover plate and opening provided in an embodiment of the present invention. The present invention provides a refrigerant-side flow channel plate, including a flow channel plate body 1 and a cover plate 4. The flow channel plate body has multiple flow channels, at least a portion of which is a closed section integrally formed by the flow channel plate body. The flow channel plate body has an opening 3 communicating with the flow channels. The cover plate 4 is disposed in the opening of the flow channel plate body. The cover plate 4 has a flange 43, which extends outward along the radial direction of the cover plate 4 and is interference-fitted with the sidewall of the opening 3, so that the cover plate 4 is radially fixed in the opening 3 of the flow channel plate body. The cover plate 4 and the opening 3 of the flow channel plate body are welded together to seal the flow channels.

[0035] It is worth noting that the refrigerant side flow channel plate can achieve radial fixation of the opening 3 and the cover plate 4 before welding through the structural arrangement of the flange portion 43, thereby achieving relative positioning and improving the reliability and yield of welding. At the same time, the pre-positioning effect of this structure can meet the welding requirements of integrated modules.

[0036] It is also worth noting that the refrigerant side flow channel plate, through the clearance fit between the cover plate 4 and the opening and the interference fit between the flange 43 and the opening, can facilitate the control and relaxation of dimensional tolerances, thereby reducing welding costs. At the same time, the interference design of the opening 3 and the partial flange 43 of the cover plate 4 results in a small pressing force, which can reduce the risk of pressing damage and reduce the performance requirements of the press, thus reducing investment and improving the yield rate.

[0037] Please refer to this again. Figure 2 and Figure 4 The outer contour of the cover plate 4 on the welding plane matches the outer contour of the opening on the welding plane.

[0038] It should be understood that in this embodiment, matching the outer contours means that the cross-section of the cover plate 4 is the same as or similar to the cross-section of the opening. This structural design ensures precise positioning of the cover plate 4 and the opening during welding, avoiding misalignment or uneven gaps. Furthermore, since the outer contours of the cover plate 4 and the opening are identical, no additional complex adjustments are required during manufacturing and assembly, reducing the impact of processing errors. The geometry of the opening can be directly matched with the cover plate 4, thereby simplifying the processing and assembly steps of the parts and saving production time and costs.

[0039] Optionally, the outer contour of the cover plate 4 on the welding plane may be circular or racetrack-shaped.

[0040] Specifically, such as Figure 4 , Figure 5 and Figure 7As shown, in this embodiment, the outer contour of the cover plate 4 can be circular. For example, the outer contours of the first cover plate 21, the second cover plate 22, the fourth cover plate 24, and the fifth cover plate 25 are all circular. It is understood that a circular outer contour has the advantage of ease of manufacturing. During assembly, the circular cover plate 4 is also easy to fit with the opening, eliminating the need for additional adjustment of the rotation direction of the cover plate 4, thus reducing alignment errors caused by its complex shape. Furthermore, the circular cover plate 4 has high resistance to deformation under multi-directional loads, which can extend the service life of the refrigerant-side flow channel plate. And as... Figure 7 As shown, in this embodiment, the outer contour of the cover plate can also be racetrack-shaped. For example, the outer contours of the third cover plate 23 and the sixth cover plate 26 are both racetrack-shaped. It is understood that in the integrated module, for flow channels with high flow resistance requirements, a rounded corner structure can be designed to reduce flow resistance. The long straight side of the racetrack shape can provide a larger welding area compared to a circle, thereby further enhancing the strength and stability of the structure. Depending on the specific implementation environment, cover plates with other outer contour shapes can also be used to adapt to the assembly requirements of the flow channel and the airtightness requirements of the component installation, such as fan-shaped cover plates, square cover plates, etc.

[0041] Please refer to this again. Figure 4 and Figure 5 The cover plate 4 is provided with at least two flange portions 43, which are evenly arranged along the outer periphery of the cover plate 4.

[0042] It is worth noting that using at least two flanges 43 facing opposite directions with an interference fit to the opening can further provide radial fixation. This prevents the cover plate 4 from being pulled to the side that solidifies first during welding, which could cause defects such as dents, porosity, and weld misalignment when the laser beam 5 reaches the other side due to excessive gap. Furthermore, the partial interference fit of the two flanges 43 results in lower pressing force compared to a full circumferential interference fit. This avoids product damage during the pressing process, facilitates the selection of the press and the relaxation of part tolerances, and significantly reduces costs. It also prevents the extrusion of large aluminum wires, thus maintaining product cleanliness. Moreover, for complex parts, such as… Figure 7 The integrated module shown often requires welding on multiple sides. On the production line, all welding cover plates 4 need to be press-fitted on a press first, and then the parts are sent to a laser welding equipment for laser welding. Interference fit can prevent the parts from falling off during the pressing, welding and flipping process, which facilitates automated production.

[0043] In an optional embodiment, the flange portion 43 is a rib structure, and the large-diameter end of the flange portion 43 is close to the cover plate 4, while the small-diameter end of the flange portion 43 is away from the cover plate 4.

[0044] It is worth noting that the large-diameter end of the flange 43 is close to the cover plate, which provides a larger contact area, facilitating a stable interference fit during assembly and welding, and improving sealing performance and welding quality. Conversely, the small-diameter end of the flange 43 is away from the cover plate, which helps guide the structure into the opening during assembly, resulting in a smoother assembly process and reducing the risk of errors or jamming. Depending on the specific implementation environment, a conical flange, a spherical crown flange, a stepped flange, or a convex bulge structure can also be used to achieve a localized interference fit between the opening 3 and the cover plate 4.

[0045] Please refer to this again. Figure 3 and Figure 6 The opening is a stepped hole. The lower end face of the cover plate 4 (i.e., the second lower end face 46 in the figure) abuts against the stepped surface of the stepped hole (i.e., the first lower end face 34 in the figure). The upper end face of the cover plate (i.e., the second upper end face 45 in the figure) is flush with the upper end face of the stepped hole (i.e., the first upper end face 31 in the figure). The flange 43 is interference-fitted with the inner wall of the stepped hole (i.e., the first side wall surface 33 in the figure), which is the interference area 6 of the flange in the figure.

[0046] It is worth noting that this structural design ensures the welding stability between the cover plate 4 and the opening 3, resulting in a smooth weld seam on the laser welding surface. Specifically, when the cover plate 4 is fully pressed into the opening 3, the lower end face of the cover plate 4 and the lower end face of the opening 3 come into contact and fit together, with the lower end face of the opening 3 providing support for the cover plate 4. At this point, the pressure increases while the stroke of the pressure rod remains unchanged, and an inflection point appears on the pressure-displacement curve, indicating that the press-fit has reached the appropriate position. Furthermore, the depth of the stepped hole in the opening 3 is the same as the thickness of the cover plate 4, allowing the upper end face of the cover plate 4 and the upper end face of the stepped hole to be on the same plane. This facilitates the setting of parameters such as the laser welding defocusing amount and results in a good welding effect and a smooth weld seam. After pressing, the side wall of the stepped hole and the flange 43 fit together tightly. The laser beam 5 acts on the opening 3 and the cover plate 4 along the fitting surface, causing them to melt and form a molten pool. The side wall of the stepped hole fits together with the side wall of the cover plate 4 (i.e., the second side wall 42 in the figure). After the cover plate 4 and the opening 3 solidify, they form an integral welded structure at the refrigerant side flow channel plate.

[0047] In this embodiment, the connection between the upper end face of the stepped hole and the inner wall of the stepped hole has a first chamfer 32, and the cover plate 4 has a second chamfer 41 that is adapted to the first chamfer 32. The cooperation between the first chamfer 32 and the second chamfer 41 can guide the cover plate 4 to be pressed into the stepped hole.

[0048] It should be understood that before laser welding, the cover plate 4 is first pressed onto the opening 3. The first chamfer 32 of the stepped hole and the second chamfer 41 on the cover plate 4 can facilitate the pressing and positioning, and have a guiding function to prevent the cover plate 4 from being pressed skewed or tilted, thus facilitating the realization of automated pressing.

[0049] In this embodiment, the outer peripheral surface of the cover plate 4 is fitted with the inner wall of the stepped hole with a clearance so that the cover plate 4 can be welded to the opening 3 of the flow channel plate body by laser welding.

[0050] It is worth noting that the use of butt welding and laser welding processes is simple and reliable, requires no solder or flux, and is energy-saving and emission-reducing, which is conducive to industrial promotion.

[0051] In this embodiment, the flow channel plate body is made of aluminum alloy and is formed by semi-solid die casting.

[0052] like Figure 7 As shown, this embodiment also provides an integrated module, including the refrigerant side flow channel plate as described above; wherein, the number of openings 3 is multiple, and the multiple openings 3 are all arranged on the refrigerant side flow channel plate 1.

[0053] In this embodiment, multiple openings 3 are arranged in slightly different directions on the refrigerant-side flow channel plate 1. It can be understood that the multiple openings 3 are arranged in slightly different directions on the refrigerant-side flow channel plate 1; that is, as shown in the figure, some openings 3 are oriented towards a vertical plane, while others are oriented towards a horizontal plane or other planes. This structural design is suitable for complex products requiring welding on multiple surfaces, preventing welding plates from falling off during the flipping process and facilitating automated production. Unified pressing followed by unified welding increases production cycle time and reduces costs.

[0054] Furthermore, the refrigerant side flow channel plate 1 in this embodiment is designed and manufactured using die casting. The basic structure of the integrated module is produced through die casting. Part of the refrigerant flow channel is formed by die casting core pulling and machining, and then the cover plate 4 is welded to the core pulling and machining holes using laser welding to seal this flow channel. For other flow channels with high flow resistance requirements, and flow channels that cannot be formed by core pulling due to interference, a rounded corner structure is designed to reduce flow resistance. This can be directly produced by die casting demolding, and then the racetrack-shaped cover plate 4 is welded to the demolding opening using laser welding to seal the flow channel. Specifically, using the laser welding method of the cover plate 4 to seal the flow channel saves space and machining costs compared to using threaded plugs with sealing rings. It also avoids problems such as aging of the sealing ring and poor performance under high and low temperature conditions, resulting in high reliability.

[0055] The integrated module provided in this embodiment also includes a refrigerant-side component. The flow channel plate body is provided with multiple external interfaces that communicate with the flow channel. The refrigerant-side component is fixedly connected to the flow channel plate body through the external interfaces.
