Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat exchangers, in particular to a brazed plate heat exchanger stacking device. Background Technique
[0002] The brazed plate heat exchanger is a heat exchange device widely used in various industrial and civil fields. Its core consists of a series of corrugated metal sheets, which are connected together through a precise brazing process to form a series of thin rectangular channels. The design of these channels aims to maximize the heat exchange efficiency while minimizing the pressure drop of the fluid during the heat exchange process. Compared with the traditional shell-and-tube heat exchanger, due to its structural compactness, the brazed plate heat exchanger can provide a larger heat exchange area within the same volume, thus achieving a higher heat exchange efficiency. Therefore, during the manufacturing process of the brazed plate heat exchanger, it is necessary to closely stack the heat exchange fins and the brazing material, and place the assembled heat exchanger into a furnace for heating. During the heating process, the brazing material melts and penetrates into the gaps between the plates. However, the traditional stacking method of using a fixture to fasten after the heat exchange fins are stacked is difficult to ensure the tightness of the stacking, and there is also a risk of the stacked heat exchange fins spreading during the handling process. Content of the Utility Model
[0003] In order to overcome the deficiencies of the above-mentioned existing problems, the utility model provides a brazed plate heat exchanger stacking device, which can conveniently stack the heat exchange fins and fix them.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a brazed plate heat exchanger stacking device, including a bottom plate, vertical frames are arranged on both sides of the bottom plate, a top plate is arranged above the bottom plate through the vertical frames, a pressing plate is also arranged between the bottom plate and the top plate, the pressing plate is connected to the top plate through a telescopic cylinder, the telescopic cylinder is arranged on the top plate, and the movable end of the telescopic cylinder is connected to the pressing plate; symmetrically arranged grooves are arranged on both the bottom plate and the pressing plate, fixing plates are arranged on the bottom plate and the pressing plate through the grooves, through holes are arranged at both ends of the fixing plate, fixing rods are arranged in the through holes, and nut sleeves are arranged at both ends of the fixing rods.
[0005] Preferably, guide grooves are arranged on the vertical frames, and guide blocks matched with the guide grooves are arranged on the pressing plate.
[0006] Preferably, a vertically arranged limiting plate is also arranged on the bottom plate.
[0007] The beneficial effects of the utility model are that the pressing plate controlled by the telescopic cylinder can evenly apply pressure to ensure the tight stacking between the heat exchange fins; the limiting plate can quickly align the heat exchange fins during stacking, greatly improving the stacking efficiency; the application of the fixing plate can prevent the stacked heat exchange fins from spreading.

Detailed Description of the Embodiments
[0012] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.
[0013] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.
[0014] According to Figure 1 and Figure 2 As shown, a brazed plate heat exchanger lamination device includes a bottom plate 1. Vertical frames 2 are arranged on both sides of the bottom plate 1. A top plate 3 is arranged above the bottom plate 1 through the vertical frames 2. A pressing plate 4 for pressing heat exchange fins and brazing filler metal is further arranged between the bottom plate 1 and the top plate 3. The pressing plate 4 is connected to the top plate 3 through a telescopic cylinder 5. The telescopic cylinder 5 is arranged on the top plate 3, and the movable end of the telescopic cylinder 5 is connected to the pressing plate 4 to control the movement of the pressing plate 4 to achieve pressing and loosening operations. Symmetrically arranged grooves are provided on both the bottom plate 1 and the pressing plate 4. Fixing plates 6 are arranged on the bottom plate 1 and the pressing plate 4 through the grooves. The fixing plates 6 are arranged in the grooves to ensure that the pressing plate 4 can apply pressure evenly. Through holes 61 are provided at both ends of the fixing plate 6. Fixing rods 7 are arranged in the through holes 61. Nut sleeves 71 are arranged at both ends of the fixing rods 7. The fixing plate 6 and the fixing rod 7 cooperate with each other to fix the heat exchange fins after pressing.
[0015] Guide grooves 21 are arranged on the vertical frames 2. Guide blocks 41 cooperating with the guide grooves 21 are arranged on the pressing plate 4. The combined use of the guide grooves 21 and the guide blocks 41 ensures the linear trajectory of the pressing plate 4 during up and down movement, preventing the pressing plate from shifting or shaking during the pressing process.
[0016] A vertically arranged limiting plate 8 is further provided on the bottom plate 1 to ensure the precise alignment of the heat exchange fins during the lamination process, thereby improving the lamination accuracy of the heat exchange fins and the solder.
[0017] During practical use, the heat exchange fins and the solder are sequentially placed on the bottom plate 1 from the side far away from the limiting plate 8. The heat exchange fins are aligned when placed through the limiting plate 8. After placement, the pressing plate 4 descends with the telescopic cylinder 5 to press the heat exchange fins to ensure the stability of the heat exchange fins during subsequent operations. Then, the fixing plate 6 is inserted from the groove position, the fixing rod 7 is arranged in the through hole 61, and the heat exchange fins are fixed by the nut sleeve 71. The pressing plate 4 descends step by step, and the heat exchange fins are gradually fixed through the fixing plate 6 until sufficient tightness is achieved. After the pressing plate 4 rises, the stacked heat exchange fins are taken out, and the stacked heat exchange fins can then be subjected to subsequent calcination processes.
[0018] This design is ingenious. The pressing plate 4 controlled by the telescopic cylinder 5 can apply pressure evenly to ensure the tight stacking of the heat exchange fins and the quality of the heat exchanger after forming; the limiting plate 8 can quickly align the heat exchange fins during lamination, greatly improving the lamination efficiency; the application of the fixing plate 6 can prevent the stacked heat exchange fins from spreading, ensuring the stability of the heat exchange fins during the lamination process and facilitating subsequent handling.
[0019] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
