Description

Technical Field

[0001] The utility model relates to the technical field of manifold manufacturing, and particularly to a pre-fixing structure for accessories of a manifold. Background Art

[0002] The manifold is one of the important components in an air-conditioning system. The function of the manifold in the air conditioner is as follows: The refrigerant in the air conditioner is compressed by a compressor to generate a high-temperature and high-pressure liquefied gas, which becomes a low-temperature and high-pressure liquid after heat dissipation and condensation through a heat exchanger, and then enters the manifold for collection.

[0003] Some of the existing manifolds adopt a butted structure composed of a slot plate and a cover plate, and are fixed by brazing. By using this brazing step, the accessories on the manifold can also be fixed by brazing, eliminating the trouble of separate welding of the accessories. Before sending the manifold and the accessories into a brazing furnace, the accessories need to be pre-fixed on the manifold.

[0004] In the existing structure, as disclosed in a manifold in the patent application with the application number CN201590001362.0 and the name "Manifold for a Heat Exchanger, Assembly Comprising Such a Manifold and Heat Exchanger", the longitudinal edges of the manifold plate (i.e., the slot plate) are positioned away from the cover in at least one area to allow subsequent crimping of the component by folding a longitudinal adjacent portion adjacent to the edge of the manifold plate over the attached component, so that a part of the component is thereby fixed between the cover and the manifold plate. However, this fixing structure is complex and has high requirements for processing, resulting in high processing costs. Therefore, the pre-fixing structure for accessories of the existing manifold needs to be further improved. Summary of the Utility Model

[0005] The purpose of the utility model is to make up for the above deficiencies and disclose to the society a pre-fixing structure for accessories of a manifold with a simple structure, convenient processing and low processing costs.

[0006] The technical solution of the utility model is realized as follows:

[0007] A pre-fixing structure for accessories of a manifold includes a manifold and accessories. The manifold is composed of a slot plate and a cover plate that are adapted to each other. At least one deformation groove is axially provided on the outer surfaces of the upper sides of both sides of the slot plate. The upper part of the slot plate is bent along the deformation groove to form a pressing part for pressing the cover plate. A hook-shaped part adapted to the deformation groove is provided on the accessory.

[0008] The measures to further optimize the technical solution are as follows:

[0009] As an improvement, 2 - 4 deformation grooves are respectively provided on the upper sides of both sides of the slot plate. By setting it like this, while making the pressing part easy to deform, the strength of the pressing part is ensured.

[0010] As an improvement, the hook-shaped part on the accessory cooperates with the lowermost deformation groove. The distance between the two sides of the lowermost deformation groove is wider, and the deformation of the lowermost deformation groove is relatively small, so that the bonding force with the hook-shaped part is better.

[0011] As an improvement, a concave cavity adapted to the pressing part is arranged on the accessory. The arrangement of the concave cavity makes the contact area between the inner surface of the accessory and the manifold larger, which is beneficial to improving the reliability of fixation during brazing.

[0012] As an improvement, the cross-section of the slot plate is in a U-shaped structure with an upward opening, and the cross-section of the cover plate is in a U-shaped structure with a downward opening.

[0013] As an improvement, an arc surface adapted to the upper surface of the cover plate is arranged on the accessory, and the arc surface is in close fit with the upper surface of the cover plate.

[0014] As an improvement, solder layers are compounded on the inner and outer surfaces of the slot plate and the cover plate. Such a setting can improve the processing efficiency and reduce the defective rate.

[0015] As an improvement, a limiting boss protruding inward is arranged on the slot plate, and the cover plate is in limiting support cooperation with the upper end of the limiting boss.

[0016] As an improvement, the limiting boss is punched from the outside to the inside on the slot plate.

[0017] The advantages of the present utility model compared with the prior art are:

[0018] The pre-fixing structure of the accessory of the manifold of the present utility model has a simple structure. By arranging a hook-shaped part on the accessory and using the deformation groove provided on the slot plate for facilitating the pressing of the cover plate as a hook groove for cooperating with the hook-shaped part, the pre-fixing between the accessory and the manifold is realized. The deformation groove integrates two functions, simplifies the structure, is convenient for processing, and has a low processing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present utility model will be further described in detail below with reference to the drawings:

[0029] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be used in other implementation manners, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present utility model.

[0030] Those skilled in the art should understand that in the disclosure of the present utility model, the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position relationship shown in the drawings. It is only for the convenience of simplifying the description of the present utility model, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0031] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one component can be one, while in other embodiments, the number of the component can be multiple. The term "one" should not be construed as a limitation on the number.

[0032] Embodiment 1, as shown in Figures 1 to 4As shown in the figure, an attachment pre-fixing structure of a manifold includes a manifold 1 and an attachment 2. The manifold 1 is composed of a slot plate 11 and a cover plate 12 that are adapted to each other. On the outer surfaces of the upper sides of the slot plate 11, deformation grooves 11a are axially provided respectively. The upper part of the slot plate 11 is bent along the deformation grooves 11a to form a pressing part 11b for pressing the cover plate 12. A hook-shaped part 2a adapted to the deformation groove 11a is provided on the attachment 2.

[0033] In order to make the pressing part 11b deform easily and ensure the strength of the pressing part 11b, 2 - 4 deformation grooves 11a are provided on the upper sides of the slot plate 11 respectively. In this embodiment, the number of deformation grooves 11a on both sides is 2 respectively, and the hook-shaped part 2a of the attachment 2 cooperates with the first deformation groove 11a from top to bottom to form a fixation.

[0034] In the attachment pre-fixing structure of the present utility model, by providing a hook-shaped part 2a on the attachment 2 and using the deformation groove 11a provided on the slot plate 11 for facilitating the pressing of the cover plate 12, the deformation groove 11a is used as a hook groove that cooperates with the hook-shaped part, realizing the pre-fixation between the attachment 2 and the manifold 1. The deformation groove 11a integrates two functions into one, simplifies the structure, is convenient for processing, and has a low processing cost.

[0035] The cross-section of the slot plate 11 is in a U-shaped structure with an upward opening, and the cross-section of the cover plate 12 is in a U-shaped structure with a downward opening.

[0036] An arc surface 2c adapted to the upper surface of the cover plate 12 is provided on the attachment 2, and the arc surface 2c is in close contact with the upper surface of the cover plate 12. The arc surface 2c is in close contact with the upper surface of the U-shaped cover plate 12, increasing the contact surface between the attachment 2 and the manifold 1, and improving the reliability of brazing.

[0037] Solder layers are compounded on the inner and outer surfaces of the slot plate 11 and the cover plate 12. The slot plate 11 and the cover plate 12 are formed by pressing a plate. Solder layers are compounded on the upper and lower surfaces of the plate. In this way, when processing the slot plate 11 and the cover plate 12, there is no need to distinguish between the front and back sides, which can improve the processing efficiency; and it also avoids the unqualified manifold products caused by the wrong placement of the front and back sides during pressing.

[0038] A limiting boss 11c protruding inwards is provided on the slot plate 11, and the cover plate 12 is in limiting support cooperation with the upper end of the limiting boss 11c.

[0039] The limiting boss 11c is punched from the outside to the inside on the slot plate 11.

[0040] When the cover plate 12 is installed, the cover plate 12 is limited and supported by the limiting boss 11c, which can improve the assembly efficiency; after the cover plate 12 is installed, the upper part of the slot plate 11 is bent along the deformation groove 11a to form a pressing part 11b, and the cover plate 12 is fixed to prevent it from shifting during brazing.

[0041] Embodiment 2, as Figures 5 to 8 shown, the accessory pre-fixing structure in this embodiment is similar to the structure in Embodiment 1. In this embodiment, the number of deformation grooves 11a on both sides is 3 respectively. The cross-section of the slot plate 11 is a U-shaped structure with an upward opening, and is symmetrically arranged on both sides. When bending the pressing part 11b, the deformation of the upper deformation groove 11a is larger, while the deformation of the lower deformation groove 11a is relatively smaller; in addition, the distance between the two lower deformation grooves 11a is wider than that of the upper deformation groove 11a.

[0042] In this embodiment, the hook-shaped part 2a on the accessory 2 cooperates with the lowermost deformation groove 11a. Since the deformation of the lower deformation groove 11a is relatively small and its groove depth is deeper, the bonding force between the hook-shaped part 2a and the deformation groove 11a is better, and the reliability of pre-fixing is better.

[0043] A cavity 2b adapted to the pressing part 11b is provided on the accessory 2. When the accessory 2 is pre-fixed to the manifold 1 by the cooperation of the hook-shaped part 2a and the deformation groove 11a, the pressing part 11b is located in the corresponding cavity 2b, and the outer surface of the pressing part 11b is in contact with the inner surface of the cavity 2b, thereby increasing the contact area between the manifold 1 and the accessory 2, further improving the reliability of brazing, reducing the leakage risk, and increasing the strength.

[0044] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
