Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to an intermittent pressurized copper tube heat exchanger. Background Technology

[0002] A copper tube heat exchanger is a device that uses copper tubes as the main heat transfer medium to achieve heat exchange between two fluids. This type of heat exchanger is widely used in various industrial, commercial and residential environments, and has become the first choice in many fields due to its good thermal conductivity, corrosion resistance and mechanical strength.

[0003] Existing heat exchangers are typically pressurized intermittently by connecting a booster pump to the copper tubes of the heat exchanger to improve fluid flow rate. However, after prolonged use, the booster pump needs to be turned on and off periodically, causing the copper tubes to be subjected to frequent pressure changes. This is especially true at segmented diameter reduction sections and threaded structures, which may lead to fatigue damage, resulting in copper tube rupture or leakage, affecting the safety of use. Once a rupture occurs, the entire damaged copper tube often needs to be replaced, resulting in high maintenance costs and inconvenience in use.

[0004] Therefore, it is necessary to design an intermittent pressurized copper tube heat exchanger that can install and disassemble the rubber expansion joint, provide buffering during heat exchange, facilitate the replacement of the rubber expansion joint, reduce maintenance costs, and improve the convenience and safety of use. Utility Model Content

[0005] To overcome the drawbacks of copper tubes repeatedly subjected to frequent pressure changes, especially at segmented diameter changes and threaded structures, which may lead to fatigue damage, resulting in copper tube rupture or leakage, and the need to replace the entire damaged copper tube once a rupture occurs, resulting in high maintenance costs, this utility model provides an intermittent pressurized copper tube heat exchanger that allows for the installation and disassembly of rubber expansion joints and provides buffering during heat exchange, facilitating the replacement of rubber expansion joints, reducing maintenance costs, and improving the convenience and safety of use.

[0006] Technical solution: An intermittent pressurized copper tube heat exchanger includes a mounting bracket, handles, a filter screen, an inlet pipe, a booster pump, valves, connecting pipes, heat exchange components, and reinforcing components. The mounting bracket has slidably detachable filter screens on both the front and rear sides, with handles attached to the upper part of each filter screen. Multiple connecting pipes are connected to the mounting bracket. A fixed pipe is located on the upper right side of the right connecting pipe, and a booster pump is connected to the lower right side of the fixed pipe. An inlet pipe is connected to the front of the booster pump. A valve is rotatably connected to the upper part of the fixed pipe. The connecting pipes are equipped with heat exchange components for installation and heat exchange. The heat exchange components are equipped with reinforcing components for strengthening the components.

[0007] As an improvement to the above solution, all connecting pipes are U-shaped.

[0008] As an improvement to the above solution, the heat exchange assembly includes rubber flexible joints, elbows, bolts, outlet pipes, and pressure sensors. The upper sides of the connecting pipes on the left and right are connected to rubber flexible joints by multiple bolts in a detachable manner. The upper sides of the left and right sides of the connecting pipe in the middle are also connected to rubber flexible joints by multiple bolts in a detachable manner. The two rubber flexible joints on the left and the two rubber flexible joints on the right are connected to elbows by multiple bolts in a detachable manner. The upper left side of the connecting pipe on the left is connected to an integrally formed outlet pipe, and the left side of the outlet pipe is connected to a pressure sensor.

[0009] As an improvement to the above scheme, all bends are curved.

[0010] As an improvement to the above solution, the reinforcement component includes a connecting plate, a screw, and a nut. The left and right sides of the bend are connected to two connecting plates, and the front and rear sides of the connecting pipe are connected to two connecting plates. The two connecting plates at the same longitudinal position are connected to a screw by a thread, and the upper and lower parts of the screw are connected to nuts by a thread. The nuts are in contact with the adjacent connecting plates.

[0011] As an improvement to the above solution, it also includes iron plates, with multiple iron plates connected to the outside of the connecting pipe.

[0012] Beneficial effects: 1. This utility model allows for the installation or removal of rubber expansion joints by rotating nuts, screws and bolts, then installing or removing the bent pipe, and then installing or removing the rubber expansion joint for replacement or cleaning, and then reinstalling and using it. This enables the installation and disassembly of the rubber expansion joint and provides buffering during heat exchange, facilitating the replacement of the rubber expansion joint, reducing maintenance costs, and improving the convenience and safety of use.

[0013] 2. In the heat exchange process, this utility model uses a filter screen to intercept and filter dust or impurities in the heat exchange medium. When the usage time is long, the filter screen can be removed by pulling the handle and then cleaned. This allows for the filtration of dust or impurities during heat exchange, preventing dust and impurities from adhering to the pipes, keeping the pipe surface clean, improving heat exchange efficiency, and facilitating filter screen cleaning.

[0014] 3. This utility model uses a screw to contact the upper connecting plate, then rotates the screw to move and contact the lower connecting plate, and continues to rotate the screw to move it to a suitable position. Then, the nut contacts the screw, and then the nut is rotated to move and contact the connecting plate for reinforcement. This can strengthen the rubber flexible joint, prevent it from loosening during use, and improve its stability. Attached Figure Description

[0021] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0022] An intermittent pressurized copper tube heat exchanger, such as Figures 1-5As shown, the system includes a mounting bracket 1, a handle 2, a filter screen 3, an inlet pipe 4, a booster pump 5, a valve 6, a connecting pipe 7, a rubber expansion joint 8, a bend 9, an iron sheet 10, bolts 11, a connecting plate 12, a screw 13, a nut 14, an outlet pipe 15, and a pressure sensor 16. The filter screen 3 is slidably and detachably connected to both the front and rear parts of the mounting bracket 1. The handle 2 is connected to the upper side of each filter screen 3. Three connecting pipes 7 are connected to the mounting bracket 1. All connecting pipes 7 are U-shaped. The upper right part of the right connecting pipe 7 has a fixed pipe, and the lower right part of the fixed pipe is connected to the booster pump 5. The inlet pipe 4 is connected to the front of the booster pump 5. The valve 6 is rotatably connected to the upper part of the fixed pipe. The upper sides of the left and right connecting pipes 7 are detachably connected to the rubber expansion joint 8 by six bolts 11. The upper sides of the left and right connecting pipes 7 are also connected by six bolts 11. The connecting pipe 7 is detachably connected to the rubber flexible joint 8. The two rubber flexible joints 8 on the left and the two rubber flexible joints 8 on the right are detachably connected to the bend pipe 9 by six bolts 11. The bend pipe 9 is arc-shaped. Thirty-four iron plates 10 are connected to the outside of the connecting pipe 7 to increase the contact area and accelerate heat exchange. The left and right sides of the bend pipe 9 are connected to the front and rear connecting plates 12. The front and rear sides of the connecting pipe 7 are connected to the left and right connecting plates 12. The two connecting plates 12 at the same longitudinal position are connected to the screw 13 by threads. The upper and lower parts of the screw 13 are connected to the nut 14 by threads. The nut 14 contacts the adjacent connecting plate 12. The upper left part of the connecting pipe 7 on the left is connected to the integrally formed water outlet pipe 15. The left side of the water outlet pipe 15 is connected to the pressure sensor 16.

[0023] When pressurization is required for copper tube heat exchange, this device can be used. The mounting bracket 1 is installed in a designated area, and then the rubber flexible joints 8 are respectively connected to the connecting pipes 7, all of which are U-shaped. The rubber flexible joints 8 are then fixed in place using bolts 11. Next, the bent pipes 9 are connected to the rubber flexible joints 8, and all of which are arc-shaped. The bent pipes 9 are then fixed in place using bolts 11. Subsequently, the screw 13 is brought into contact with the upper connecting plate 12. The screw 13 is then rotated to move it into contact with the lower connecting plate 12. The screw 13 is then rotated further until it reaches a suitable position. The nut 14 contacts the screw 13, and then the nut 14 is rotated to move and contact the connecting plate 12 for reinforcement, thereby reinforcing the rubber flexible joint 8, preventing loosening during use, and improving stability. Then, an external water source is connected through the inlet pipe 4, and the valve 6 is opened, and the booster pump 5 is started for intermittent pressurization, allowing water to enter the inlet pipe 4, then flow into the fixed pipe, and then into the connecting pipe 7. It flows through the rubber flexible joint 8 and the bend 9 for heat exchange. The iron plate 10 increases the contact area and accelerates heat exchange. Finally, the water is discharged from the outlet pipe 15, thus achieving cold water heat exchange. During the heat exchange process... The rubber flexible joint 8 provides cushioning, the pressure sensor 16 monitors the pressure inside the pipeline, and the filter screen 3 intercepts and filters dust or impurities in the heat exchange medium. When used for an extended period, the filter screen 3 can be removed by pulling the handle 2, then cleaned, and finally placed in contact with the mounting bracket 1. This allows for the filtration of dust or impurities during heat exchange, preventing dust and impurities from adhering to the pipeline surface, maintaining pipeline cleanliness, improving heat exchange efficiency, and facilitating the cleaning of the filter screen 3. When the device has been used for a long time and the rubber flexible joint 8 is worn... If a fault occurs, the valve 6 can be turned in reverse to close it, then the nut 14 can be turned in reverse to move and remove it, then the screw 13 can be turned to remove it, then the bolt 11 can be turned to remove it, then the bend 9 can be removed, and then the rubber expansion joint 8 can be removed for replacement or cleaning. Then the above operations can be repeated to install and reinforce the rubber expansion joint 8 and the bend 9, so that the rubber expansion joint 8 can be installed and disassembled and buffered during heat exchange, which facilitates the replacement of the rubber expansion joint 8, reduces maintenance costs, and improves the convenience and safety of use. After replacement, the valve 6 can be turned to open it to continue heat exchange. After use, the booster pump 5 can be turned off.
