[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] Reference Figures 1-6 This embodiment provides a split-flow heat exchanger and its internally threaded copper tube assembly, comprising:
[0034] The heat exchanger housing 1 has a heat exchange chamber inside it, an inlet pipe 11 is connected to the top of the heat exchanger housing 1, and an outlet pipe 12 is connected to the bottom of the heat exchanger housing 1.
[0035] The flow divider 13 is fixedly installed on the side of the heat exchanger shell 1, and the flow divider 13 is provided with a number of water passage holes;
[0036] The cover cylinder 14 has a sealing cover mounted on the diversion plate 13. Two medium input pipes 15 are connected to the cover cylinder 14. A drain pipe is provided at the bottom of the cover cylinder 14. An inspection port assembly 2 is mounted on the cover cylinder 14.
[0037] T-shaped baffle 16 is fixedly installed on the diversion plate 13. The T-shaped baffle 16 divides the diversion plate 13 into three areas. The upper two areas are connected to the two cover cylinders 14 respectively, and the lower one area is connected to the drain pipe at the bottom of the cover cylinder 14.
[0038] Two sealing covers 17 are respectively installed on the two upper areas to ensure that the three areas are set independently.
[0039] Multiple medium copper tubes 18 are installed in the water passage holes of the diversion plate 13. The inlet of the medium copper tube 18 is located in two areas above the diversion plate 13, and the outlet of the medium copper tube 18 is located in the area below the diversion plate 13. The main body of the medium copper tube 18 is located inside the heat exchanger shell 1.
[0040] In this embodiment, the same medium enters the two cover cylinders 14 through the two medium inlet pipes 15 on the cover cylinder 14 respectively; since the T-shaped baffle 16 divides the diversion plate 13 into three areas, and the upper two areas are respectively connected to the two cover cylinders 14, after the medium enters the cover cylinder 14, it will further flow into the two independent areas above the diversion plate 13; this partitioned entry method can ensure that the medium can more evenly cover the area above the diversion plate 13, avoiding the situation where some water passage holes cannot enter the medium due to the large area of the diversion plate 13; The inlet of the copper tube 18 is located in two areas above the flow divider 13, and the outlet is located in the lower area. The medium enters the inlet of the copper tube 18 from the area above the flow divider 13 through the water passage and flows inside the copper tube 18. The main body of the copper tube 18 is located inside the heat exchanger shell 1. The medium flowing inside the copper tube 18 exchanges heat with the fluid in the heat exchange chamber through the tube wall. The internal thread structure of the internally threaded copper tube increases the turbulence of the fluid, disrupts the fluid boundary layer, and increases the degree of turbulence. To enhance heat exchange efficiency, the heat-exchanged medium flows out from the outlet of the medium copper tube 18 and enters the area below the distribution plate 13. This area connects to the drain pipe at the bottom of the cover cylinder 14, and the heat-exchanged medium is ultimately discharged through the drain pipe. Simultaneously, an inlet pipe 11 is connected to the top of the heat exchanger shell 1, and an outlet pipe 12 is connected to the bottom. Fluid in the heat exchange chamber enters through the inlet pipe 11, exchanges heat with the medium in the medium copper tube 18, and then exits through the outlet pipe 12. Two medium input pipes 15 are provided to allow the medium to enter the area above the distribution plate 13 in separate zones. The internally threaded copper tubes ensure uniform distribution of the medium within each medium copper tube 18, avoiding the problems of excessive fluid flow and insufficient heat exchange in some areas, as well as insufficient fluid flow and dead zones in some areas, caused by uneven fluid distribution in traditional heat exchangers. This improves the overall heat exchange efficiency and reduces energy consumption. The application of internally threaded copper tubes further enhances the heat exchange effect. The threaded structure on the inner wall increases fluid disturbance, disrupts the fluid boundary layer, and increases the degree of fluid turbulence, allowing heat to be transferred more quickly between the two fluids.
[0041] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, an exhaust pipe 1a is connected to the top of the heat exchanger shell 1;
[0042] In this embodiment, during the operation of the split-flow heat exchanger, two fluids exchange heat in the heat exchange chamber inside the heat exchanger shell 1. When the heat exchanger is working, the fluid in the heat exchange chamber generates gas due to temperature changes. This gas accumulates in the heat exchange chamber, and as the gas continues to be generated, the pressure in the heat exchange chamber gradually increases. Since an exhaust pipe 1a is connected to the top of the heat exchanger shell 1, when the pressure in the heat exchange chamber reaches a certain level, the gas will be discharged to the outside of the heat exchanger shell 1 through the exhaust pipe 1a, thereby maintaining the pressure in the heat exchange chamber within a relatively stable range and ensuring that the heat exchanger can operate normally. During the heat exchange process, the generation of gas is unavoidable. Without the exhaust pipe 1a, as the gas continues to accumulate, the pressure in the heat exchange chamber will continue to rise, which will not only damage the structure of the heat exchanger but may also cause a safety accident. The exhaust pipe 1a can discharge the gas in a timely manner, keeping the pressure in the heat exchange chamber within a safe range and ensuring the structural integrity and operational safety of the heat exchanger.
[0043] Specifically, such as Figure 1 As shown, a waste pipe 1b is connected to the bottom of the heat exchanger shell 1;
[0044] In this embodiment, during the operation of the split-flow heat exchanger, two fluids exchange heat in the heat exchange chamber inside the heat exchanger shell 1. As the heat exchange process continues, the fluid in the heat exchange chamber may carry some impurities, which will gradually accumulate in the heat exchange chamber. When the impurities accumulate to a certain extent at the bottom of the heat exchange chamber, the operator can open the waste drain pipe 1b to allow the impurities in the heat exchange chamber, along with some fluid, to be discharged from the outside of the heat exchanger shell 1 through the waste drain pipe 1b, thereby keeping the heat exchange chamber clean, ensuring that the fluid can flow smoothly in the heat exchange chamber, and allowing the fluid to fully contact the medium copper tube 18, improving heat exchange efficiency and reducing energy consumption. The long-term accumulation of impurities in the heat exchange chamber may cause wear and corrosion to the inner wall of the heat exchanger shell 1 and the surface of the medium copper tube 18, shortening the service life of the equipment. Regularly discharging impurities through the waste drain pipe 1b can reduce the damage of impurities to the equipment, extend the service life of the equipment, and reduce the maintenance and replacement costs of the equipment.
[0045] More specifically, such as Figure 1 As shown, two lifting lugs 1c are symmetrically arranged on the top of the heat exchanger shell 1;
[0046] In this embodiment, the symmetrically arranged lifting lugs 1c ensure that the heat exchanger is subjected to uniform force during hoisting and transportation, preventing tilting, shaking, or even falling due to uneven force distribution. This reduces safety risks during installation and transportation, ensuring the personal safety of personnel and the integrity of the equipment. The lifting lugs 1c provide convenient hoisting points for the installation and maintenance of the heat exchanger. Personnel can quickly and accurately connect the hoisting equipment to the lifting lugs 1c, improving work efficiency and reducing the time and labor costs required for installation and maintenance. At the same time, during maintenance, the heat exchanger can be easily hoisted away from its installation position, facilitating a comprehensive inspection and repair of the equipment.
[0047] Furthermore, such as Figure 5 As shown, a guide plate 1d is provided on the inner wall of the flow divider 13. The guide plate 1d is located at the center of the upper and lower regions. Multiple reinforcing plates 1e are arranged at the upper and lower ends of the guide plate 1d. The reinforcing plates 1e are used to fix the medium copper tube 18. The guide plate 1d is used to guide the heat exchange liquid entering the heat exchanger shell 1, so that the heat exchange liquid flows along the tube path of the medium copper tube 18.
[0048] In this embodiment, the heat exchange fluid enters the heat exchange chamber from the inlet pipe 11 at the top of the heat exchanger shell 1. At this time, the guide plate 1d located at the center of the inner wall of the flow divider 13 begins to function. Due to the arrangement of the guide plate 1d, it guides the heat exchange fluid entering the heat exchange chamber, allowing the heat exchange fluid to be distributed more evenly and flow towards the direction of the medium copper tube 18, avoiding disorderly diffusion of the heat exchange fluid in the heat exchange chamber. Under the guidance of the guide plate 1d, the heat exchange fluid flows along the tube path of the medium copper tube 18. The heat exchange fluid can fully contact the tube wall of the medium copper tube 18 and the medium copper tube 18. Another medium flows inside the tube 18 for heat exchange; the guide plate 1d ensures that the heat exchange fluid can flow along a predetermined path, increasing the contact area and contact time between the heat exchange fluid and the medium copper tube 18; the multiple reinforcing plates 1e arranged at the upper and lower ends of the guide plate 1d play a role in fixing the medium copper tube 18 during the flow of the heat exchange fluid; when the heat exchange fluid flows, it will generate a certain impact force on the medium copper tube 18, and the reinforcing plates 1e can prevent the medium copper tube 18 from shaking or displacing due to the impact force, ensuring the stability of the medium copper tube 18 in the heat exchange cavity, thereby ensuring the smooth progress of the heat exchange process.
[0049] Furthermore, such as Figure 5 As shown, multiple reinforcing crossbars 1f are inserted between each reinforcing plate 1e on the same side;
[0050] In this embodiment, the reinforcing crossbar 1f and the reinforcing plate 1e work together to greatly enhance the stability of the medium copper tube 18. During the flow of the heat exchange fluid, the shaking and vibration of the medium copper tube 18 can be effectively reduced, avoiding fatigue damage, deformation or even rupture of the medium copper tube 18 due to long-term shaking, thus ensuring the normal operation of the heat exchanger.
[0051] Furthermore, such as Figure 6 As shown, the access panel assembly 2 includes:
[0052] The cover plate 21 of the cover cylinder is a sealing cover installed on the cover cylinder 14, and the cover plate 21 of the cover cylinder is provided with an inspection port;
[0053] The bracket 22 is fixedly installed on the cover plate 21 of the cover cylinder;
[0054] A pull rod 23 is inserted into a bracket 22. A lifting block 24 is threaded onto the top of the pull rod 23. The lifting block 24 is used to fix the pull rod 23.
[0055] The hinge seat 25 is oscillatingly positioned at the bottom end of the pull rod 23;
[0056] The inspection cover 26 is fixedly connected to the hinge seat 25, and the inspection cover 26 is sealed on the inspection port of the cover plate 21 of the cover cylinder;
[0057] In this embodiment, when the heat exchanger needs maintenance, the operator simply moves the bottom of the maintenance cover 26 to open it by swinging it open with the hinge seat 25. After the maintenance cover 26 is opened, the operator can inspect, repair, or replace parts inside the cover cylinder 14 through the maintenance port. When the maintenance cover 26 is damaged or needs to be replaced, the lifting block 24 is turned to disengage it from the pull rod 23, and then the maintenance cover 26 is opened and pulled down to remove it. The design of the maintenance port assembly 2 allows the operator to easily open and close the maintenance port for inspection and maintenance of the heat exchanger. Compared with traditional heat exchangers, maintenance can be performed without disassembling a large number of parts, which greatly improves maintenance efficiency, reduces equipment downtime, and lowers maintenance costs.
[0058] Furthermore, such as Figure 6 As shown, a pull ring 27 is provided at the top of the lifting block 24;
[0059] In this embodiment, the pull ring 27 makes it easier for the operator to operate the lifting block 24 when opening and closing the inspection port; the pull ring 27 provides a convenient point of force, and the operator can easily apply rotational force through the pull ring 27 to quickly tighten or loosen the lifting block 24, which greatly improves the convenience of operation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
