Description

Technical Field

[0001] This utility model relates to the field of heat exchanger fin technology, specifically an anti-collapse heat exchanger fin structure. Background Technology

[0002] Finned heat exchangers are a widely used type of heat exchange equipment in gas-liquid heat exchangers. They enhance heat transfer by adding fins to heat exchange base tubes such as stainless steel tubes and copper tubes. Currently, most fins lack external protective structures. During installation, if the fins are subjected to improper pressure or collision, they are prone to deformation or collapse. Sometimes, to prevent the fin surface from being corroded by corrosive media, which would lead to corrosion and thinning of the fins and a reduction in pressure resistance, fin oil is usually applied to the fins. However, most fin structures are not designed to facilitate the application of fin oil. Utility Model Content

[0003] The purpose of this invention is to provide an anti-collapse heat exchanger fin structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A collapse-resistant heat exchanger fin structure includes:

[0006] A heat exchange base tube is provided with fixed fins on its outer side and multiple movable fins are slidably connected to the outer side of the heat exchange base tube. Connecting ropes are fixed between two adjacent movable fins and between the fixed fins and the movable fins.

[0007] A protective assembly is arranged on the outside of the heat exchange base tube. The protective assembly includes two rotating rings that are rotatably connected to the heat exchange base tube. Multiple fixing blocks are fixed on the outside of the rotating rings. A protective rod is detachably installed and fixed between two oppositely arranged fixing blocks. The protective rod can limit the position of the movable fins on the heat exchange base tube.

[0008] An oil-immersed assembly is detachably fitted onto the outside of a heat exchange base tube. The oil-immersed assembly includes two adaptable and spliced ​​semi-cylindrical shells, with a connecting pipe fixedly connected to the outside of each semi-cylindrical shell.

[0009] Furthermore, a connecting flange is fixed to one end of the connecting pipe away from the semi-cylindrical shell, and the connecting flange is used to connect the connecting pipe to an external pipeline for conveying finned oil.

[0010] Furthermore, both ends of the heat exchange base tube are provided with rotating grooves, and the rotating ring is rotatably connected to the rotating grooves.

[0011] Furthermore, each of the four corners of the semi-cylindrical shell is fixed with a connecting lug, and a bolt is detachably fixed between two adjacent connecting lugs.

[0012] Furthermore, a sealing gasket is fitted and fixed at the opening of the semi-cylindrical shell.

[0013] Furthermore, both ends of the protective rod are fixed with connecting blocks, and studs are screwed between the connecting blocks and the fixing blocks.

[0014] Furthermore, the outer side of the protective rod is provided with multiple arc-shaped notches at equal intervals, and the arc-shaped notches are used to restrict the position of the movable fins.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Multiple protective rods are arranged in a ring at equal angles around the heat exchange base tube. Each protective rod has an arc-shaped notch on its outer side. The arc-shaped notch can be engaged with the edge of the corresponding fin (including fixed fins and movable fins). This allows multiple protective rods to support and protect the outer side of multiple fins, effectively preventing the fins from deforming and collapsing due to collision or compression. This helps to improve the structural strength and anti-collapse performance of the fins.

[0017] 2. By sliding multiple movable fins towards the fixed fins, the multiple fins are centrally arranged on the outer side of the middle of the heat exchange base tube. Then, two semi-cylindrical shells are sleeved and fixed on the outer side of the multiple fins of the heat exchange base tube. Existing fin oil is injected into the cylindrical body formed by the two semi-cylindrical shells through the connecting pipe, so that the multiple fins can be immersed in fin oil for oiling protection. Afterwards, the oil in the cylindrical body is pumped out through the connecting pipe, and the cylindrical body is removed. This achieves simultaneous oiling of multiple fins to improve their corrosion resistance and effectively prevents the fins from being corroded by corrosive media. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, please refer to Figure 1 - Figure 5 In this embodiment of the present invention, an anti-collapse heat exchanger fin structure includes a heat exchange base tube 100. Fixed fins 110 are fixed to the outer side of the middle portion of the heat exchange base tube 100. Multiple movable fins 120 are slidably connected at equal intervals to the outer sides of both ends of the middle portion of the heat exchange base tube 100. The fixed fins 110 and the movable fins 120 are identical in size and shape. Connecting ropes 121 are fixed between adjacent movable fins 120 and between the fixed fins 110 and the movable fins 120. A protective assembly 200 is installed on the outside of the heat exchange base tube 100 to restrict the position of the movable fin 120 on the heat exchange base tube 100. The protective assembly 200 includes two rotating rings 210 that are rotatably connected to the corresponding ends of the heat exchange base tube 100. Multiple fixing blocks 220 are fixed at equal angles on the outside of the rotating rings 210. A protective rod 230 is detachably fixed between two fixing blocks 220 at opposite positions. The fixed fin 110 and the movable fin 120 are both movably engaged with the protective rod 230.

[0026] Specifically, multiple protective rods 230 are evenly arranged on the outside of multiple fins (including fixed fins 110 and movable fins 120) on the conventional heat exchange base tube 100. The two ends of the protective rods 230 are installed and fixed to the ends of the heat exchange base tube 100. The arc-shaped notch 231 on the outside of the protective rods 230 is engaged with the edge of the fin to protect the outside of the fin. At the same time, the multiple protective rods 230 can improve the structural strength of the multiple fins installed on the heat exchange base tube 100, thereby effectively preventing the fins from collapsing due to accidental squeezing and collision, and improving the fins' ability to resist collapse to a certain extent.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, both ends of the heat exchange base tube 100 are provided with rotating grooves 130, and the rotating ring 210 is rotatably connected to the rotating grooves 130, so that the protective rods 230 and studs 240 at different positions can be rotated to different positions outside the heat exchange base tube 100. At this time, the edge of the fins slides at the arc-shaped notch 231 of the protective rod 230, which makes it convenient for the user to use existing power tools to rotate the studs 240 at different positions in one position, thereby facilitating the installation and removal of the protective rods 230.

[0028] like Figure 1 As shown, in this embodiment, the fixed fin 110 is fixed in the middle of the heat exchange base tube 100, and multiple movable fins 120 are arranged at equal intervals on both sides of the fixed fin 110. Connecting ropes 121 are fixed between adjacent movable fins 120 and between the fixed fin 110 and the movable fins 120. When installing multiple fins, the movable fins 120 are pulled away from the fixed fin 110 to make the connecting ropes 121 taut, so that multiple fins can be arranged at equal intervals on the outside of the heat exchange base tube 100 for heat dissipation.

[0029] In this embodiment, both the fixed fin 110 and the movable fin 120 are designed to gradually thin from the center to the edge, thereby providing a larger contact area between the fins and the heat exchange base tube 100, which is beneficial to improving the structural strength of the fins connected to the heat exchange base tube 100.

[0030] like Figure 4 As shown, in this embodiment, both ends of the protective rod 230 are fixed with connecting blocks 232, and the connecting blocks 232 and the fixing blocks 220 are screwed together with studs 240. The studs 240 can screw the connecting blocks 232 and the fixing blocks 220 together, so as to install and fix the protective rod 230 on the fixing blocks 220.

[0031] like Figure 2 As shown, in this embodiment, the outer side of the protective rod 230 is provided with multiple arc-shaped notches 231 at equal intervals. The arc-shaped notches 231 are used to restrict the position of the movable fins 120. When the protective rod 230 is installed, the edge of the fins is engaged in the arc-shaped notches 231, so that the movable fins 120 cannot slide freely along the heat exchange base tube 100.

[0032] Example 2: Based on Example 1, in order to impregnate multiple fins with fin oil to prevent the fin surface from being corroded by corrosive media and further improve the structural strength of the fins.

[0033] like Figure 4 and Figure 5As shown, in this embodiment, an oil-immersing assembly 300 is detachably sleeved on the outside of the heat exchange base tube 100. The oil-immersing assembly 300 includes two adaptable and spliced ​​semi-cylindrical shells 310. The two semi-cylindrical shells 310 can be combined to form a cylindrical body. A connecting pipe 320 is fixedly connected to the outside of the semi-cylindrical shells 310. The connecting pipe 320 is used to deliver finned oil to the cylindrical body.

[0034] Specifically, by moving multiple movable fins 120 closer together in the center, and then fixing two semi-cylindrical shells 310 around the multiple fins, fin oil is injected into the semi-cylindrical shells 310 through the connecting pipe 320, so that the multiple fins can be soaked in oil, improving the corrosion resistance of the fins and preventing the fins from affecting their structural strength due to corrosion.

[0035] like Figure 4 As shown, in this embodiment, a connecting flange is fixed to one end of the connecting pipe 320 away from the semi-cylindrical housing 310. The connecting flange is used to connect the connecting pipe 320 to the external pipeline for conveying fin oil. One of the two connecting pipes 320 is connected and fixed to the external pipeline for conveying fin oil, and the other connecting pipe 320 is connected and fixed to the external pipeline for extracting fin oil, thereby realizing the conveying or extraction of fin oil into the space between the two semi-cylindrical housings 310.

[0036] In this embodiment, connecting lugs 330 are fixed at the four corners of the semi-cylindrical shell 310, and bolts are detachably fixed between two adjacent connecting lugs 330, so that the two semi-cylindrical shells 310 can be installed and fixed together to form a cylindrical body.

[0037] like Figure 5 As shown, in this embodiment, a sealing gasket 340 is fitted and fixed at the opening of the semi-cylindrical housing 310, which helps to improve the sealing of the connection position of the two semi-cylindrical housings 310 and effectively prevents fin oil leakage.

[0038] In this embodiment, after the multiple movable fins 120 have moved centrally, the connecting rope 121 is in a slack state.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
