Technical Field

[0001] This utility model relates to the field of heat exchanger tube assembly technology, specifically a high-efficiency enhanced heat exchanger tube assembly with a guide plate. Background Technology

[0002] The heat exchanger tube assembly is the core component of a heat exchanger, consisting of multiple heat exchange tubes and related components, used to achieve heat exchange between two media.

[0003] For example, the utility model application with application number 202121986848.8 discloses a high-efficiency pressure-resistant and shock-resistant heat exchange tube for a closed cooling tower. The heat exchange tube group similar to the above application still has the following shortcomings: the heat exchange tube group usually adopts a simple hollow pipe structure, which is not convenient to enhance the heat exchange effect by adding guide plates inside and outside, resulting in relatively poor heat exchange efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency enhanced heat exchange tube assembly with a guide plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency enhanced heat exchange tube assembly with a guide plate, comprising a support base, a heat exchange tube body, and a cleaning component. Four support rods are fixed on both sides of the upper part of the support base, and fixing rods are welded at equal intervals on the inner side of the support rods. A support ring is installed at one end of each fixing rod, and the heat exchange tube body is disposed inside the support ring. An outer guide plate is fixed to the outer wall of the heat exchange tube body, and an inner guide plate is fixed to the inner wall of the heat exchange tube body. A cleaning component is installed on the outer side of the heat exchange tube body, and the cleaning component includes a cleaning scraper ring, scraper grooves, and connecting blocks. The cleaning scraper ring has a ring-shaped structure, and eight scraper grooves are evenly distributed on the inner side of the cleaning scraper ring. Connecting blocks are fixed between adjacent cleaning scraper rings.

[0006] Furthermore, the outer guide plates are evenly distributed in an array about the center line of the heat exchange tube body, and the outer edge of the outer guide plates has a wavy structure.

[0007] Furthermore, the inner guide plate on the inner wall of the heat exchange tube body has a spiral structure, and the surface of the inner guide plate is coated with a hydrophobic layer.

[0008] Furthermore, a movable component is installed at the top of the fixed rod, and the movable component includes a side frame and a waterproof motor, with the waterproof motor installed on the outer side of the side frame.

[0009] Furthermore, the movable component also includes a lead screw and a movable sleeve, with the lead screw rotatably mounted inside the side frame and the movable sleeve fitted on the outer side of the lead screw.

[0010] Furthermore, the movable component also includes a connecting rod, the movable sleeve is slidably connected to the inner wall of the side frame, and the outer side of the movable sleeve is connected to the connecting rod, and the connecting rod is fixedly connected to the cleaning scraper ring.

[0011] Furthermore, the cleaning scraper ring is slidably connected to the outer side of the heat exchange tube body, and the scraper groove is located on the outside of the outer guide plate and is slidably connected to the outer guide plate.

[0012] Furthermore, the heat exchange tube bodies are parallel to each other, and the ends of the heat exchange tube bodies are connected to connecting bends, which are U-shaped tubes.

[0013] This utility model provides a high-efficiency enhanced heat exchange tube assembly with a guide plate, which has the following beneficial effects: This utility model is equipped with a heat exchange tube body, and several heat exchange tube bodies constitute a heat exchange tube group inside the heat exchanger. The outer guide plate on the outside of the heat exchange tube body can guide the heat exchange fluid inside the heat exchanger to radially scour along the circumference of the heat exchange tube body, avoiding the fluid flowing around the heat exchange tube body. The outer edge of the outer guide plate has a wavy structure, which causes the flowing fluid to generate multiple secondary eddies, thereby increasing its contact frequency with the outer wall of the heat exchange tube body and improving the heat exchange efficiency. The inner guide plate has a spiral structure, which makes the fluid inside the heat exchange tube body flow in a spiral shape, which facilitates the enhancement of the turbulence of the fluid, destroys the thermal boundary layer, and thus improves the heat transfer efficiency.

[0014] This utility model is equipped with a cleaning component. A waterproof motor facilitates the rotation of the lead screw, which in turn moves the outer movable sleeve of the lead screw. The movable sleeve then moves the connecting rod and the cleaning scraper rings. The cleaning scraper rings are fixedly connected by connecting blocks for synchronous movement. The cleaning scraper rings are slidably connected to the outer surface of the heat exchange tube body, allowing multiple cleaning scraper rings to move and clean the outer surface of multiple heat exchange tube bodies to prevent scale buildup. At the same time, the scraping grooves of the cleaning scraper rings correspond to the outer guide plate, enabling them to clean the sides of the outer guide plate, thereby preventing scale buildup on the surface of the heat exchange tube body and the outer guide plate from affecting heat exchange.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, a high-efficiency enhanced heat exchanger tube assembly with guide plates includes a support base 1, a heat exchanger tube body 5, and a cleaning component 9. Four support rods 2 are fixed on both sides of the upper part of the support base 1, and fixing rods 3 are welded at equal intervals on the inner side of the support rods 2. A support ring 4 is installed at one end of each fixing rod 3, and the heat exchanger tube body 5 is disposed inside the support ring 4. An outer guide plate 6 is fixed to the outer wall of the heat exchanger tube body 5, and an inner guide plate 7 is fixed to the inner wall of the heat exchanger tube body 5. Eight outer guide plates 6 are evenly distributed in an array about the center line of the heat exchanger tube body 5, and the outer edge of the outer guide plate 6 has a wavy structure. The inner guide plate 7 on the inner wall of the heat exchanger tube body 5 has a spiral structure, and the surface of the inner guide plate 7 is coated with a hydrophobic layer. The heat exchanger tube bodies 5 are parallel to each other, and the ends of the heat exchanger tube bodies 5 are connected by connecting bends. The tube 10 is connected to the bend 10 in a "U" shape. The support rings 4 on both sides are used to support the two sides of the heat exchange tube body 5. The heat exchange tube bodies 5 are connected by the bend 10. Several heat exchange tube bodies 5 constitute the heat exchange tube group inside the heat exchanger. The outer guide plate 6 on the outside of the heat exchange tube body 5 can guide the heat exchange fluid inside the heat exchanger to radially scour along the circumference of the heat exchange tube body 5, avoiding the fluid from flowing around the heat exchange tube body 5. The outer edge of the outer guide plate 6 has a wavy structure, which makes the fluid flowing through it generate multiple secondary vortices, thereby increasing its contact frequency with the outer wall of the heat exchange tube body 5 and improving the heat exchange efficiency. The inner guide plate 7 has a spiral structure, which makes the fluid inside the heat exchange tube body 5 flow in a spiral shape, which is conducive to enhancing the turbulence of the fluid, destroying the thermal boundary layer, and thus improving the heat transfer efficiency.

[0019] like Figures 1-3As shown, a movable component 8 is installed at the top of the fixed rod 3. The movable component 8 includes a side frame 801 and a waterproof motor 802. The waterproof motor 802 is installed on the outer side of the side frame 801. The movable component 8 also includes a lead screw 803 and a movable sleeve 804. The lead screw 803 is rotatably installed inside the side frame 801, and the movable sleeve 804 is sleeved on the outer side of the lead screw 803. The movable component 8 also includes a connecting rod 805. The movable sleeve 804 is slidably connected to the inner wall of the side frame 801, and the connecting rod 805 is connected to the outer side of the movable sleeve 804. The connecting rod 805 is fixedly connected to the cleaning scraper ring 901. A cleaning component 9 is installed on the outer side of the heat exchange tube body 5. The cleaning component 9 includes a cleaning scraper ring 901, scraper grooves 902, and connecting block 903. The cleaning scraper ring 901 has a ring-shaped structure, and eight scraper grooves 902 are evenly opened on the inner side of the cleaning scraper ring 901. Adjacent cleaning scraper rings 901... A connecting block 903 is fixed between 01. The cleaning scraper ring 901 is slidably connected to the outer side of the heat exchange tube body 5. At the same time, the scraper groove 902 is located on the outer side of the outer guide plate 6 and is slidably connected to the outer guide plate 6. The waterproof motor 802 facilitates the rotation of the lead screw 803, thereby driving the movement of the outer moving sleeve 804 of the lead screw 803. The moving sleeve 804 drives the connecting rod 805 and the cleaning scraper ring 901 to move. The cleaning scraper rings 901 are fixedly connected by the connecting block 903 to facilitate synchronous movement. The slidable connection between the cleaning scraper ring 901 and the outer side of the heat exchange tube body 5 allows multiple cleaning scraper rings 901 to move and clean the outer surface of multiple heat exchange tube bodies 5 to prevent scale buildup. At the same time, the scraper groove 902 of the cleaning scraper ring 901 corresponds to the outer guide plate 6 so that it can clean the side of the outer guide plate 6, thereby preventing scale from adhering to the surface of the heat exchange tube body 5 and the outer guide plate 6 and affecting heat exchange.

[0020] In summary, as Figures 1-4 As shown, in use, the high-efficiency enhanced heat exchanger tube assembly with guide plates can first install the corresponding heat exchanger shell on the outside of the support base 1, and then set up the heat exchanger tube body 5 and the connecting bend 10, so that the support rings 4 on both sides support the two sides of the heat exchanger tube body 5. During the process, the outer guide plate 6 on the outside of the heat exchanger tube body 5 can guide the heat exchange fluid inside the heat exchanger to radially flush along the circumference of the heat exchanger tube body 5, avoiding the fluid from flowing around the heat exchanger tube body 5. The outer edge of the outer guide plate 6 has a wavy structure, which makes the flowing fluid generate multiple secondary vortices, thereby increasing its contact frequency with the outer wall of the heat exchanger tube body 5 and improving the heat exchange efficiency. The inner guide plate 7 has a spiral structure, which makes the fluid inside the heat exchanger tube body 5 flow in a spiral shape, which is conducive to enhancing the turbulence of the enhanced fluid, destroying the thermal boundary layer, and thus improving the heat transfer efficiency. In use, the waterproof motor 802 can drive the lead screw 803 to rotate, thereby driving the outer moving sleeve 804 of the lead screw 803 to move. The moving sleeve 804 then drives the connecting rod 805 and the cleaning scraper ring 901 to move. The cleaning scraper rings 901 are fixedly connected by the connecting block 903 and can move synchronously. The cleaning scraper ring 901 is slidably connected to the outer side of the heat exchange tube body 5, allowing multiple cleaning scraper rings 901 to move and clean the outer surface of multiple heat exchange tube bodies 5 to prevent scale buildup. At the same time, the scraping groove 902 of the cleaning scraper ring 901 corresponds to the outer guide plate 6, enabling it to clean the side of the outer guide plate 6, thereby preventing scale from adhering to the surface of the heat exchange tube body 5 and the outer guide plate 6 and affecting heat exchange. This completes the use process of the high-efficiency enhanced heat exchange tube group with guide plate.
