Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and in particular to a novel heat exchanger. Background Technology
[0002] A chemical heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical production, and they are widely used as heaters, coolers, condensers, evaporators, and reboilers.
[0003] For example, Chinese utility model patent (CN221549408U) discloses a heat exchanger for chemical industry, which describes: "Hot water inside the shell exchanges heat with cold water in the outer serpentine heat exchange tube from the outside in, and hot water in the inner serpentine heat exchange tube exchanges heat with cold water in the outer serpentine heat exchange tube from the inside out, thus forming a simultaneous heat exchange effect inside and outside. This allows the cold water in the outer serpentine heat exchange tube to quickly and fully contact the heat in the hot water, which is conducive to achieving a rapid heat exchange effect, thus effectively saving heat exchange time and ensuring heat exchange efficiency." It also describes the technical problem that "during the heat exchange process, the cold water in the center of the serpentine heat exchange tube often has insufficient contact with the heat."
[0004] In summary, the existing technology has the following technical problems: the filtration effect of hot water on impurities and scale in the hot water is not ideal when hot water enters the heat exchanger, which leads to scale clogging of the heat exchanger and makes pipeline replacement inconvenient. Therefore, this application proposes a new type of heat exchanger to solve the above-mentioned technical problems and provide a new technical solution. Utility Model Content

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0033] As in the background art, when hot water enters the heat exchanger, the filtration effect on impurities and scale contained in the hot water is not ideal, which leads to scale clogging the heat exchanger and makes it inconvenient to replace the pipeline.
[0034] To solve this technical problem, this utility model provides a novel heat exchanger that is applied to heat exchangers.
[0035] For details, please refer to Figures 1-8 The new type of heat exchanger specifically includes:
[0036] Heat exchange cylinder 1, with flow dividers 2 fixedly connected to both ends of heat exchange cylinder 1, inspection covers 3 fixedly connected to the ends of the two flow dividers 2 away from heat exchange cylinder 1, heat exchange interfaces 8 fixedly connected to the top of the two flow dividers 2, liquid inlet interface 6 fixedly connected to the upper end of one end of heat exchange cylinder 1, and liquid drain interface 7 fixedly connected to the lower end of the other end of heat exchange cylinder 1.
[0037] The heat exchange tube 10 is installed inside the heat exchange cylinder 1. The heat exchange tube 10 is arranged in a spiral. There are multiple heat exchange tubes 10, which are arranged in a ring array. The two ends of each heat exchange tube 10 are connected to the flow divider 2 at the same end.
[0038] Sealing components 9 are provided at the connection between heat exchanger 1 and flow divider 2, and at the connection between flow divider 2 and inspection cover 3.
[0039] The novel heat exchanger provided by this utility model features a detachable design for the heat exchange cylinder 1, the flow divider 2, and the inspection cover 3. This allows the heat exchange tube 10 inside the heat exchange cylinder 1 to be removed, facilitating the cleaning or replacement of any blocked heat exchange tube 10. Furthermore, the heat exchange tube 10 has a spiral design and a square cross-section, which effectively increases the heat exchange area and length, thereby ensuring efficient heat exchange.
[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0041] Example 1:
[0042] Please refer to Figures 1-8 A novel heat exchanger comprising:
[0043] Heat exchange cylinder 1, with flow dividers 2 fixedly connected to both ends of heat exchange cylinder 1, inspection covers 3 fixedly connected to the ends of the two flow dividers 2 away from heat exchange cylinder 1, heat exchange interfaces 8 fixedly connected to the top of the two flow dividers 2, liquid inlet interface 6 fixedly connected to the upper end of one end of heat exchange cylinder 1, and liquid drain interface 7 fixedly connected to the lower end of the other end of heat exchange cylinder 1.
[0044] Furthermore, the heat exchange tube 10 is provided inside the heat exchange cylinder 1. The heat exchange tube 10 is arranged in a spiral. There are multiple heat exchange tubes 10, which are arranged in a ring array. The two ends of each heat exchange tube 10 are connected to the flow divider 2 at the same end.
[0045] Furthermore, sealing components 9 are provided at the connection between heat exchange cylinder 1 and flow divider 2, and at the connection between flow divider 2 and inspection cover 3.
[0046] It can be seen that by removing the inspection cover 3, the inside of the flow divider 2 can be cleaned, and the slight blockage at the end of the heat exchange tube 10 can be cleared. By removing the flow dividers 2 at both ends of the heat exchange tube 1, one or more heat exchange tubes 10 inside the heat exchange tube 1 can be taken out for cleaning or replacement. During installation, the two ends of the heat exchange tube 10 are respectively inserted into the sealing plates 11 on the two flow dividers 2. After the two ends of the heat exchange tube 10 are respectively inserted into the two flow dividers 2, the two flow dividers 2 are pushed towards the heat exchange tube 1, and the flow dividers 2 are made to fit with the end of the heat exchange tube 1, thereby realizing the installation of the heat exchange tube 10.
[0047] Specifically, the sealing assembly 9 includes an m-shaped sealing ring 14, which is sleeved on the outside of the connection between the heat exchange cylinder 1 and the flow divider 2, and the connection between the flow divider 2 and the inspection cover 3. Annular clamping plates 15 are provided on both sides of the m-shaped sealing ring 14. The m-shaped sealing ring 14 and the annular clamping plates 15 on both sides are fixedly connected by multiple fixing bolts 16. The m-shaped sealing ring 14 has two cavities inside. The ends of the heat exchange cylinder 1 and the flow divider 2 are located inside the two cavities, respectively. The ends of the flow divider 2 and the inspection cover 3 are located inside the two cavities, respectively.
[0048] It can be seen that the heat exchange cylinder 1 and the flow divider 2, the flow divider 2 and the inspection cover 3 are surrounded by the two sides and the middle of the m-shaped sealing ring 14, and the two annular clamps 15 squeeze the two sides of the m-shaped sealing ring 14 to achieve a double sealing effect.
[0049] Furthermore, the bottom of the heat exchange cylinder 1 is supported by the bracket 4, and the upper end of the bracket 4 is connected to the heat exchange cylinder 1 by the fixing bracket 5.
[0050] Example 2:
[0051] The novel heat exchanger provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, the heat exchange tube 10 has a rectangular cross-section.
[0052] Through the above structural design, the square cross-section design of heat exchange tube 10 can effectively increase the heat exchange area.
[0053] Example 3:
[0054] The novel heat exchanger provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown, a sealing plate 11 is fixedly connected to one end of the flow divider 2 near the heat exchanger 1. A connection port 12 is provided on the sealing plate 11. The end of the heat exchanger tube 10 is inserted into the flow divider 2 through the connection port 12. A sealing ring is provided at the connection between the heat exchanger tube 10 and the connection port 12.
[0055] The above structural design effectively ensures the sealing of the connection between the heat exchange tube 10 and the sealing plate 11.
[0056] Example 4:
[0057] The novel heat exchanger provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown, a flow divider 13 is provided inside the flow divider 2. One end of the flow divider 13 is fixedly connected to the sealing plate 11, and the other end of the flow divider 13 is attached to the inner wall of the inspection cover 3.
[0058] Through the above structural design, the flow divider 13 makes the inside of the flow divider cylinder 2 an annular channel, thereby allowing the heat exchange liquid to flow into the multiple heat exchange tubes 10 more quickly.
