Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a corrosion-resistant U-shaped tube dry evaporator. Background Technology

[0002] U-tube dry evaporators are key heat exchange equipment in refrigeration systems. The refrigerant evaporates and absorbs heat inside the U-tube, which cools the refrigerant outside the tube. They are commonly used in air conditioning, cold storage, and other applications. The U-tube structure allows them to adapt to temperature changes and prevents the refrigerant from entering the compressor before it is fully evaporated, thus ensuring stable system operation.

[0003] In existing U-tube dry evaporators, the interior of the U-tubes is prone to corrosion during actual operation. This is because the refrigerant flowing inside the tubes during evaporation may contain impurities such as moisture and acidic substances. These impurities circulate with the refrigerant, constantly eroding the inner wall of the U-tube and causing chemical corrosion of the metal tube. Furthermore, the constant temperature and pressure changes inside the tubes during refrigerant evaporation and heat absorption accelerate the corrosion reaction. Over time, the inner wall of the U-tube gradually thins, leading to pitting and other corrosion problems. In severe cases, this can even cause refrigerant leakage, affecting the normal operation and service life of the evaporator. Therefore, we propose a corrosion-resistant U-tube dry evaporator. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the inside of the U-shaped tube is prone to corrosion.

[0005] To solve the above technical problems, this application provides a corrosion-resistant U-tube dry evaporator, including a main pipe, with multiple baffles sleeved on the outer side of each of the multiple main pipes, a connecting plate slidably engaged inside each of the multiple baffles, and a fixing plate fixedly connected to the top and bottom of each of the multiple baffles.

[0006] In some embodiments, each of the plurality of main pipes is provided with a mounting component, the mounting component including a mounting ring fixedly connected to the outer end of the main pipe, a sealing sleeve fixedly connected to each of the plurality of mounting rings, a fastening ring sleeved on each of the plurality of sealing sleeves, and a screw threaded into each of the plurality of fastening rings.

[0007] The main tube is externally connected to a connecting tube, an input tube, and an output tube.

[0008] A processing unit is disposed within the main pipe, and the processing unit includes a drive component, the drive component of which is provided with a fan blade.

[0009] In some embodiments, the drive component includes a ring body disposed within the main tube, and a plurality of rubber blocks are fixedly connected to the outside of the ring body, wherein the ring body and the rubber blocks are configured in three groups.

[0010] In some embodiments, the drive unit further includes a rotating shaft rotatably connected between the three ring bodies, and a plurality of fan blades are fixedly connected to the outside of the rotating shaft.

[0011] The processing unit also includes a cleaning component, which is equipped with a scraper for removing corrosive substances from the inner wall of the main pipe.

[0012] In some embodiments, the cleaning component includes a plurality of external rods fixedly connected to the outside of the rotating shaft. The plurality of external rods are configured in two groups, which are arranged opposite to each other, and a plurality of scrapers are fixedly connected between the two groups of external rods.

[0013] In some embodiments, each of the two fixing plates has a slot, and multiple fixing rods are inserted between the two fixing plates through the slot.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a processing unit, the entire processing unit is placed inside the main pipe. The rubber block set on the outside of the ring body tightly abuts against the inner wall of the main pipe to fix it. Then, when there is refrigerant flowing inside the main pipe, it will drive multiple fan blades to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives two sets of external rods to rotate, which in turn drives multiple scrapers to rotate, which can scrape off and clean the corrosive substances on the inner wall of the main pipe. In this way, the corrosion resistance of the U-shaped pipe can be improved.

[0016] The connecting plate can be removed, allowing the main pipe to be detached from the multiple spoilers, facilitating the replacement of the cleaning and treatment unit and further improving corrosion resistance. Attached Figure Description

[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. Example 1

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A corrosion-resistant U-tube dry evaporator includes a main pipe 1, multiple baffles 2 are sleeved on the outside of multiple main pipes 1, a connecting plate 7 is slidably engaged in the multiple baffles 2, and a fixing plate 8 is fixedly connected to the top and bottom of multiple baffles 2.

[0027] The main pipe 1 is externally connected to a connecting pipe 3, an input pipe 4, and an output pipe 5. The diameters of the input pipe 4, the output pipe 5, and the connecting pipe 3 are the same.

[0028] Furthermore, by setting up connecting pipe 3, multiple main pipes 1 can be connected for circulation, and input pipe 4 and output pipe 5 are used for refrigerant input and output;

[0029] Processing unit 6 is located inside main pipe 1. Processing unit 6 includes drive unit 61, and fan blade 614 is installed inside drive unit 61.

[0030] like Figure 2 and Figure 3 As shown, the drive unit 61 includes a ring 611 disposed inside the main tube 1, and a plurality of rubber blocks 612 are fixedly connected to the outside of the ring 611. The ring 611 and the rubber blocks 612 are configured in three groups.

[0031] Furthermore, by setting the rubber block 612, since the rubber block 612 is compressible, the ring body 611 can be tightly fitted inside the main tube 1;

[0032] The drive unit 61 also includes a rotating shaft 613 rotatably connected between the three rings 611, and a plurality of fan blades 614 are fixedly connected to the outside of the rotating shaft 613;

[0033] Furthermore, by setting the fan blade 614, the fan blade 614 can drive the rotating shaft 613 to rotate;

[0034] The processing unit 6 also includes a cleaning component 62, which has a scraper 622 for removing corrosive substances from the inner wall of the main pipe 1, wherein:

[0035] like Figure 2 and Figure 3 As shown, the cleaning component 62 includes multiple external rods 621 fixedly connected to the outside of the rotating shaft 613. The multiple external rods 621 are configured in two groups, which are arranged opposite to each other. Multiple scrapers 622 are fixedly connected between the two groups of external rods 621.

[0036] Furthermore, by setting scraper 622, since the material of scraper 622 is flexible, corrosive substances on the inner wall of the main pipe 1 can be removed without damaging the inner wall of the main pipe 1.

[0037] When in use, when there is refrigerant flowing in the main pipe 1, it will drive multiple fan blades 614 to rotate, which in turn drives the rotating shaft 613 to rotate. The rotating shaft 613 then drives two sets of external rods 621 to rotate, which in turn drives multiple scrapers 622 to rotate. Example 2

[0038] Please see Figures 1-6 This utility model provides a technical solution:

[0039] Unlike Embodiment 1, each of the multiple spoilers 2 has a connecting plate 7 slidably engaged inside it, and each of the multiple spoilers 2 has a fixing plate 8 fixedly connected to its top and bottom.

[0040] Furthermore, the connecting plate 7 can be removed, at which point the main pipe 1 can be detached from the multiple spoilers 2, making it convenient to replace the cleaning and treatment unit 6;

[0041] Both fixing plates 8 have slots 9, and multiple fixing rods 10 are inserted between the two fixing plates 8 through the slots 9.

[0042] Furthermore, by setting the slot 9 and the fixing rod 10, the fixing rod 10 can be inserted between the two fixing plates 8, thus fixing the connecting plate 7, and vice versa;

[0043] Multiple main pipes 1 are provided with mounting parts 11. The mounting parts 11 include mounting rings 111 fixedly connected to the outer end of the main pipes 1. Multiple mounting rings 111 are fixedly connected to sealing sleeves 112. Multiple sealing sleeves 112 are fitted with fastening rings 113. Multiple fastening rings 113 are threaded with screws 114.

[0044] Furthermore, rotating the screw 114 can tighten the retaining ring 113 and the sealing sleeve 112, thereby strengthening the connection between the connecting pipe 3, the input pipe 4, and the output pipe 5 and the main pipe 1.

[0045] The working principle is as follows: the entire processing unit 6 is placed inside the main pipe 1. The rubber block 612 on the outside of the ring body 611 is tightly pressed against the inner wall of the main pipe 1 to fix it. Then, when there is refrigerant flowing in the main pipe 1, it will drive multiple fan blades 614 to rotate, which in turn drives the rotating shaft 613 to rotate. The rotating shaft 613 drives two sets of external rods 621 to rotate, which in turn drives multiple scrapers 622 to rotate, which can scrape and clean the corrosive substances on the inner wall of the main pipe 1.
