Description

Technical Field

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

[0002] As an important fitting connected to a heat exchanger, the manifold adopts a tubular structure. Some of the existing manifolds adopt a butting structure composed of a slot plate and a cover plate. For example, a manifold disclosed 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" includes a cover and a manifold plate (i.e., a slot plate) welded to each other. In this manifold structure, in order to longitudinally limit the position of the cover, a stepped surface is additionally machined in the manifold plate, which greatly increases the processing cost. In addition, in the existing manifolds, spacers are provided to partition the space inside the manifold. For example, in the manifold structure disclosed in the patent application with the application number CN202021650587.8 and the name "A New Type of Docking Manifold Assembly Structure", the positioning of the spacer is achieved through the cooperation of a partition boss and a groove. However, since the partition boss is provided at the bottom of the spacer, it is difficult to ensure that the spacer is perpendicular to the manifold plate. Therefore, the existing manifold structures need to be further improved. Summary of the Utility Model

[0003] The purpose of the utility model is to make up for the above deficiencies and disclose to the society a manifold structure with simple and reasonable structure, convenient processing and low processing cost.

[0004] The technical solution of the utility model is realized as follows:

[0005] A manifold structure includes a slot plate and a cover plate that are adapted to each other. A spacer is arranged inside the slot plate. A plurality of groups of spacer positioning members protruding inwards are arranged inside the slot plate. Each group of spacer positioning members includes two pairs of limiting bosses arranged on both sides of the slot plate. A slot adapted to the spacer is arranged between each pair of limiting bosses. A limiting surface for limiting the cover plate is arranged at the upper end of the limiting boss.

[0006] The measures to further optimize the technical solution are as follows:

[0007] As an improvement, a positioning groove is arranged on the cover plate, and a convex block adapted to the positioning groove is arranged on the spacer. Arranging the positioning groove on the cover plate can timely detect whether the spacer is missing before brazing, thereby reducing the defective rate of the product.

[0008] As an improvement, the cross-section of the slot plate is in a U-shaped structure with an opening upwards, and the cross-section of the cover plate is in a U-shaped structure with an opening downwards.

[0009] As an improvement, the upper part of the slot plate is bent inwards to form a pressing part. The pressing part can pre-fix the cover plate and the internal spacer, preventing the displacement of the cover plate.

[0010] As an improvement, at least one deformation groove is axially arranged on the pressing part.

[0011] As an improvement, the number of the deformation grooves is 2 - 5.

[0012] The arrangement of the deformation grooves makes the deformation of the pressing part easier, enabling the pressing part to better fit the outer surface of the cover plate.

[0013] As an improvement, solder layers are compounded on both side surfaces of the slot plate, the cover plate and the spacer. This setting can improve the processing efficiency and reduce the defective rate.

[0014] As an improvement, the limiting boss is punched from the outside to the inside on the slot plate.

[0015] As an improvement, flat tube grooves are arranged at intervals on the slot plate.

[0016] The advantages of the present utility model compared with the prior art are as follows:

[0017] The manifold structure of the present utility model is simple and reasonable. By setting a spacer positioning member, the limiting bosses in the spacer positioning member are arranged in pairs, a slot is arranged between each pair of limiting bosses, and a limiting surface is arranged at the upper end of the limiting boss. Here, the limiting boss has two functions. One is to limit and install the spacer by using the slot, and the other is to limit the cover plate by using the limiting surface. This manifold structure realizes the above two functions by using the limiting boss, simplifies the structure, reduces the processing difficulty, and can also reduce the processing cost.

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings:

[0025] 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 other obvious deformations can be thought of by those skilled in the art. The basic principles defined in the following description of the present utility model can be used in other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present utility model.

[0026] Those skilled in the art should understand that in the disclosure of the present utility model, the orientation or position indicated by terms such as "longitudinal", "lateral", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or position relationship shown in the accompanying 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 limiting the present utility model.

[0027] 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, and in other embodiments, the number of this component can be multiple. The term "one" should not be construed as limiting the quantity.

[0028] As Figures 1 to 5 shown, a manifold structure includes a slot plate 1 and a cover plate 2 that are adapted to each other. A spacer 3 is arranged in the slot plate 1. A plurality of groups of spacer positioning members protruding inwards are arranged in the slot plate 1. Each group of spacer positioning members includes two pairs of limiting bosses 4 arranged on both sides of the slot plate 1. A slot 4a adapted to the spacer 3 is arranged between each pair of limiting bosses 4. A limiting surface 4b for limiting the cover plate 2 is arranged at the upper end of the limiting boss 4.

[0029] The manifold structure of the present utility model is provided with several groups of spacer positioning members in the slot plate 1. The spacer positioning members adopt paired limiting bosses 4. There is a slot 4a between each pair of limiting bosses 4, and a limiting surface 4b is arranged at the upper end of the limiting boss 4. With such a design, the limiting boss 4 mainly has the following two functions. First, the slot 4a between the limiting bosses 4 can be used to install the spacer 3. Second, the limiting surface 4b can limit the installation of the cover plate 2. That is to say, when installing the cover plate 2, pressing down the cover plate 2 makes the lower end surface of the cover plate 2 abut against the limiting surface 4b, which can improve the assembly efficiency. In the present utility model, the limiting boss 4 integrates two functions, which can simplify the structure, reduce the processing difficulty and the processing cost. In addition, through the cooperation of the paired limiting bosses 4 and the spacer 3, the effective welding area is increased, the welding strength can be improved, and the leakage risk can be reduced.

[0030] A positioning groove 2a is arranged on the cover plate 2, and a convex block 31 adapted to the positioning groove 2a is arranged on the spacer 3. In this way, by arranging the positioning groove 2a on the cover plate 2, when the spacer 3 is installed in the slot 4a between the limiting bosses 4 of the slot plate 1 and the cover plate 2 is covered, the convex block 31 on the spacer 3 will protrude from the positioning groove 2a. Since the cover plate 2 is fed into the brazing furnace during brazing, by observing the convex block 31 protruding from the positioning groove 2a, it can be directly judged whether the spacer 3 is installed, thus avoiding the unqualified products caused by the missing installation of the spacer 3. At the same time, it can also check whether the position of the spacer 3 is installed wrongly.

[0031] At the same time, by using the slot 4a between the limiting bosses 4 and the positioning groove 2a to pre-fix the spacer 3 at the same time, the reliability of the pre-fixation of the spacer 3 can be further ensured.

[0032] The cross-section of the slot plate 1 is in a U-shaped structure with an upward opening, and the cross-section of the cover plate 2 is in a U-shaped structure with a downward opening.

[0033] The upper part of the slot plate 1 is bent inward to form a pressing part 11. After the cover plate 2 is installed, the pressing part 11 is bent inward to pre-fix the cover plate 2 and prevent the cover plate 2 from shifting during brazing.

[0034] In order to make the pressing part 11 deform easily, at least one deformation groove 11a is axially arranged on the pressing part 11.

[0035] In this embodiment, the number of the deformation grooves 11a is 2. In order to make the pressing part 11 deform easily and ensure the strength of the pressing part 11, the number of the deformation grooves 11a is generally set to 2 - 5. The number of the deformation grooves 11a can be determined according to the size of the manifold.

[0036] Both side surfaces of the slot plate 1, the cover plate 2 and the spacer 3 are compounded with solder layers. The slot plate 1 and the cover plate 2 are formed by plate molding, and the spacer 3 is made by plate stamping. Solder layers are compounded on both side surfaces of the plate. In this way, when processing the slot plate 1 and the cover plate 2, there is no need to distinguish between the front and back sides, which can improve the processing efficiency; it also avoids the unqualified current collector products caused by the reverse placement of the front and back sides during molding.

[0037] The described limiting boss 4 is punched from the outside to the inside on the slot plate 1.

[0038] The slot plate 1 is provided with flat tube grooves 1a at intervals, and the flat tube grooves 1a are used for the installation of flat tubes. According to needs, the flat tube grooves 1a can be arranged continuously at intervals or in a segmented manner at intervals. The interval distance is generally uniformly arranged, and of course, non-uniform intervals can also be adopted.

[0039] 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 accordingly. For those skilled in the art, it should be able to realize that the solutions obtained by equivalent substitution and obvious changes made by using the description and illustrated content of the present invention should all be included in the protection scope of the present invention.
