Abstract
Description
Technical Field
[0001] This utility model relates to the field of baffle plate technology, and in particular to a baffle plate for protecting finned heat exchange tubes. Background Technology
[0002] Finned tube heat exchangers are high-efficiency, compact heat exchange devices. Their working principle primarily utilizes fins to increase the contact area and turbulence between fluids, thereby enhancing heat transfer. However, finned tubes are easily damaged when inserted into baffles. Conventional baffle structures are prone to fin collisions, damaging the heat exchange tubes and reducing the heat exchange capacity at the damaged fins, failing to achieve the designed heat exchange effect. For a long time, baffle structures have been avoided in the design and selection of finned tube heat exchangers, or protective structures have been added to the baffles, which has limited the application range of finned tube heat exchangers and increased manufacturing difficulty and cost. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a baffle plate to protect finned heat exchange tubes. In view of the problem that it is difficult to insert the baffle plate into the finned tube heat exchanger, the baffle plate is installed in the finned tube instead of the finned tube being inserted into the baffle plate. This provides a reliable installation method for the manufacture of finned tube heat exchangers, and is especially suitable for finned tube heat exchangers with large size and heavy weight.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a baffle plate for protecting finned heat exchange tubes, wherein a plurality of tube holes of the same size as the finned heat exchange tubes are provided on the baffle plate, characterized in that the baffle plate is composed of a plurality of parallel strip support plates, the tube holes are segmented structures, and a single tube hole is composed of rings arranged on adjacent strip support plates.
[0005] Furthermore, the finned heat exchange tube is embedded in the tube hole, and the finned heat exchange tube and the strip support plate are stacked together, with adjacent strip support plates welded and fixed.
[0006] Furthermore, a gap is provided between adjacent strip support plates, the gap being located at the horizontal center line of the tube hole.
[0007] Furthermore, the gap width is 0.4-0.8 mm.
[0008] Furthermore, welding notches are provided at the ends of the adjacent strip support plates. The welding notches are segmented structures distributed on the adjacent strip support plates, and the angle of the welding notches is 60°.
[0009] Compared with the prior art, the beneficial effects of this utility model include: by adjusting the baffle plate to be composed of multiple parallel strip support plates and setting tube holes between adjacent strip support plates, the installation process of inserting finned tubes into the baffle plate is improved. The baffle plate is installed into the finned tubes, and the strip support plates are formed by dividing the baffle plate. The finned tubes can be inserted into the tube bundle without obstruction. After each layer of finned tubes is in place, the strip support plate is pressed on. The next strip support plate is welded firmly to the previous strip support plate, and the support plates are welded into one piece. This ensures the disturbance effect of the baffle plate, improves the heat exchange performance of the heat exchanger, and the installation process is simple and efficient. It can protect the heat exchanger and reduce costs. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0016] A baffle plate for protecting finned heat exchange tubes, such as Figure 1As shown, several tube holes 2 of the same size as the finned heat exchange tubes are provided on the baffle plate to facilitate the installation and fixation of the finned heat exchange tubes. The aforementioned baffle plate is composed of several parallel strip support plates 1. The tube holes 2 have a segmented structure. Each tube hole 2 is composed of rings arranged on adjacent adjustment support plates. That is, the tube holes 2 are fixedly opened on adjacent strip support plates 1. For example, the upper strip support plate 1 has a partial ring that forms the tube hole 2, and the lower strip support plate 1 has the remaining partial ring that can form the aforementioned tube hole 2. When the two are combined, they form a complete tube hole 2.
[0017] like Figure 2 As shown, a gap 3 is provided between adjacent strip support plates 1. In some embodiments, the aforementioned gap 3 is located at the horizontal center line of the pipe hole 2. That is, a semi-circular ring forming the pipe hole 2 is provided on the upper strip support plate 1, and another semi-circular ring forming the aforementioned pipe hole 2 is provided on the lower strip support plate 1. It is worth noting that the width of the aforementioned gap 3 is 0.4-0.8 mm.
[0018] In practical use, the finned heat exchange tubes are inserted into the tube bundle layer by layer from bottom to top. Each layer of finned tubes has a strip support plate 1 pressed onto it, and each strip support plate 1 is welded securely after installation, thus forming a complete baffle. For example... Figure 3 As shown, in order to facilitate the welding process, welding notches 4 are provided at the ends of adjacent strip support plates 1. The aforementioned welding notches 4 are segmented structures distributed on adjacent strip support plates 1, and the angle of the welding notches 4 is 60°.
[0019] By adjusting the baffle to be composed of multiple parallel strip support plates 1, and setting tube holes 2 between adjacent strip support plates 1, the installation process of inserting finned tubes into the baffle is improved. The baffle is installed into the finned tubes, and the strip support plates 1 are formed by dividing the baffle. The finned tubes can be inserted into the tube bundle without obstruction. After each layer of finned tubes is in place, the strip support plate 1 is pressed on. The next strip support plate 1 is welded firmly to the previous strip support plate 1, and the support plates are welded into one piece. This ensures the disturbance effect of the baffle, improves the heat exchanger's heat exchange performance, and the installation process is simple and efficient. It can protect the heat exchanger and reduce costs.
[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
